2.2 Utilization stone stone resources in
order to reduce waste in the process of the loss , in addition to the
introduction of new equipment to improve the level of processing technology ,
the most important thing is to research and development of waste utilization
technology of stone , the stone waste into resources, high value . Currently the
comprehensive utilization of waste stone main ways : the use of scrap
production of stone mosaic stone , the use of waste rock , waste powder and
artificial production of artificial synthetic stone shaped stone . In
recent years, Nanjing University and the Guangdong Yunfu City, the relevant enterprises
to develop a close research cooperation, locally produced annually for
approximately 400,000 t of waste powder, conducted a series of comprehensive
utilization of waste rock R & D work . The use
of waste material such as an inorganic filler , an unsaturated polyester resin
as a binder , adding an appropriate amount of paint , curing initiator, and
other auxiliary agents , the cured molding of polyester artificial marble . The
implementation of this technology can consume large amounts of waste material ,
not only for scrap stone stone enterprises to solve the problem provides a
better way , but also to achieve efficient use of stone resources . Zhou
Zhonghua and other waste material published on the use of cement-based
artificial stone production processes, using waste rock alternative
cement-based paint manufacturing artificial stone , both to solve the original
problem of uneven color , but also to make waste material has been effectively
utilized.
CHINA
STONE VENEER residue , waste powder, etc. can also be
used to produce foundry sand , chemical products fillers, paint coatings and
waterproof construction materials. As has
been described in Yuyao and other waste powder as the main raw material,
bonding agents and additives developed into a stone- coating, the production
process is simple, small investment in equipment , stone waste utilization. In
addition, powder, add the appropriate cement carbide , pressure embryo by
mixing the curing agent , can be made of new materials , the use of waste
material as described above , waste powder preparation unburned stone composite
board substrates.
In
addition, waste rock , waste coal powder used for living , not only can reduce
the amount of coal , combustion and desulfurization can also play a role in
reducing the amount of SO2 escape of harmful gases , improve indoor air quality
; in the welding electrode manufacturing adding an appropriate
amount of powder, slag can play a role in preventing air from entering into the
weld puddle and arc . Stone processing
waste rock produced pulp , after solid-liquid separation and drying can be used
as cement raw materials , can be used as the production of coatings , plastics,
rubber, filling material .
2.3
stone dust, waste water pollution control in the stone processing is often accompanied
by a lot of dust , waste generation , with the development of society, the
stone processing industry calls for continuous improvement of environmental
protection and improve the stone factory environment , reduce dust and water
pollution stone processing enterprises
more and more attention. Measures
in the prevention of dust pollution , some enterprises in the use of advanced
stone processing equipment, dust-proof , equipped with the appropriate cleaning
device , but also organizational and technical personnel research to improve
production technology, innovative processing technology, radically reduce
pollutant emissions. If
the artificial stone granular materials during transport , open transport
environment is likely to cause a lot of dust . Yunfu
breton new building materials Co., through technical innovation , the use of
stone aggregates can guarantee delivery in the closed state , the gas delivery
technology is relatively mature technology and equipment to transport stone
aggregates, technical personnel in several key technologies on the gas
delivery system was innovative transformation, a final settlement of the stone
aggregates transportation methods exist problems of environmental pollution and
waste of resources , while reducing energy consumption , improve production
efficiency.
Most
CHINA STONE VENEER processing
enterprises are using cutting machining stone plate , in the process of water
cooling tools ( abrasive ) , excluding debris and clean the surface , resulting
in a large number of industrial wastewater . As
the stone processing wastewater main pollutants suspended solids in wastewater
treatment processing technology , to take flocculation, sedimentation and other
treatment processes can be realized stone processing plant wastewater discharge
standards and reuse . Such
as Zhang Yunfeng et al reported using flocculation and filtration processes on
stone processing wastewater . Shanghai
Fei BM universe Italian company to introduce technology to build a stone
processing plant centralized sewage treatment system , used in domestic stone
processing enterprises , reducing the dust pollution , while improving
processing wastewater recycling.
The founding of China's stone industry
started reform and opening up of China's CHINA MANUFACTURED
STONE VENEER industry has been developing rapidly, to
the 1990s, China's stone exports , production and consumption has been achieved
in the world. In
recent years, driven by the rapid development of the national economy , the
stone industry efforts to overcome the international financial crisis, the
import and export volume continued to grow, in 2010 the national stone import
and export volume , a larger number than the 2009 increase , respectively,
6.395 billion U.S. $
33.86 million t, compared with 2009 increased by 26.26% and 15.41% . In 2011,
Chinese stone import and export total 3720 million t, an increase of 9.5% ;
export volume accumulated $ 7.6 billion , an increase of 18.0% . Stone import
and export volumes continue to grow , indicating that the country has a huge
consumer market and a strong stone stone processing capacity, China has become
the true sense of the world stone big country .
However,
with the rapid development of stone industry , stone processing some of the
issues have been revealed, in the stone processing ore serious waste of
resources , stone uncontrolled discharge of waste causing environmental
pollution and ecological damage seriously restricting the stone industry sustainable development.
A stone processing problems
China
has abundant stone resources, but the resources in the stone mining and
processing is still widely used in traditional production methods , processing
technology, equipment behind , not only affects the production efficiency of
stone , causing stone blocks finished product rate , product quality varies not
Qi , but
also in the sawing and grinding process produces a large scrap, sawdust and
other waste debris , a direct result of the stone serious waste of resources .
In
addition, many stone processing companies do not take full advantage of the
processing of waste generated , causing serious waste of resources , stone
processing wastewater discharge to the surrounding water bodies caused serious
pollution, the production process dust uncontrolled discharge of staff , the
surrounding masses of the body generated a great
deal of harm.
Overall , China's
stone industry, control of resources is not strong enough , stone processing
production on the protection of the environment is poor. Take a resource-saving and
environment-friendly , sustainable development is the inevitable development of
stone industry , but also the era 's most basic requirements. Efficient use
of stone resources , enhance innovation stone processing , stone processing to
reduce pollution on a resource-saving and environment- friendly society is of
great significance.
2 CHINA STONE VENEER efficient use of resources and energy saving measures
2.1 improve
stone processing technique to reduce the level of stone in the process steps is
to reduce the consumption of resources of stone waste generation . Most waste from stone
cutting and stone polishing process to remove the human factor , but mainly by
the processing equipment and technology decisions . Improved
cutting methods and uses narrow kerf sawing tools , machining high precision
polishing equipment are blocks of stone enterprises to effectively reduce the
attrition rate , improve productivity and increase economic way . As new technologies emerge , stone
processing equipment has been continuously improved , processing technology has
also been improved. Saws , saw, saw
the emergence of a more combinations to make sheet metal processing technology
took a big step forward , significantly improve production efficiency , waste
of resources has also been effectively controlled. In recent
years, ultra efficient portfolio as the successful development of circular saw
blades , automatic continuous polishing mill applications , have made production
efficiency has increased substantially, the waste generated during processing
is also significantly reduced.
Another major stone consumption
reduction measures that the economical use of stone materials . With
the increased level of processing technology , more and more stone products to
the development of thin , compared to the traditional decorative stone panels ,
thin , ultra-thin stone stone resources conservation , energy conservation and
environmental protection, in practical applications can greatly reduce the body
load, reducing project cost. With
the ultra-thin thickness of the profile and fixed technologies , the board
automatic polishing and grinding , and other key technology matures , the
current marble thinnest up 2 mm, maximum size can be achieved 1 200 mm × 2 400
mm, granite slabs thinnest
of up to 3 mm, size can be as large as 1 200 mm × 1 200 mm. Substrate by a thin stone and stone
composite made of a new type of decorative material --- thin stone composite
panels . After
several years of rapid development, processing technology ladder, and gradually
showing a light weight , high strength, utilizing waste environmental
protection, conservation of mineral resources and other non- composite natural
stone products are difficult to match a significant advantage . Such
as Nanjing University and the Guangdong Yunfu City Jinrui Stone Co., Ltd.
jointly conduct research and development , the use of waste as raw material
stone developed a stone composite panels can be used as a low-cost substrate unburned
board for the production of stone composite panels provide a kind of low-cost, better performance of the substrate . While
taking advantage of new and improved production equipment , new bonding
technology for ultra-thin stone broke , and thickness and composite technology
for the research and development , and ultimately develop a resource-saving
ultra-thin stone composite panels , the finished stone panel thickness of only 2 ~ 3 mm.
Doors standardization in the industry has
been very high voice . The
upcoming December 1 this year, the full implementation of the Chinese wood
windows and doors industry 's first national standards - "wood doors
" GB/T29498-2013, wood industry will undoubtedly further promote the
standardization process .
However,
some industry insiders told reporters , as China's housing industry promotion
and doors industry technology continues to progress , standardized production
of wooden doors is increasingly becoming a trend , but mainly in the custom
door market environment, from the full implementation of policies to , may also need a long transition period .
stone coated metal roofing tile Customized dominant
Although
the industry has always been the voice on the doors of standardization
constantly, but it is undeniable that our industry is still in custom wooden
stage , wooden 70% to 80 % are factory customization.
It
is understood that the basic process is the custom doors : Customers first
select the door style, texture, color , and then talk about the price and
businessmen , on a good price point of sale by the door staff to the site field
measurements , the amount will be finished dimensions doors styles, sizes reported to door
manufacturing plant , began to enter the doors of the production chain .
"It
is because of the doors of businesses to accept orders for custom multi-
business -based, so the scale of production is often limited to a certain area
, it is difficult to form large -scale wooden doors ." One door in this
industry observer told reporters .
According to the
Chinese door industry research report shows that as of the end of 2011 ,
Chinese door industry production companies have more than 11,000 . Among them, mostly small
businesses , often cottage , poorly equipped, poorly managed , and the lack of
independent innovation and intellectual property.
In
view of this , there are also views that the domestic wood industry is still
not copy the experience of Europe and the doors of businesses , because
large-scale production caused by pressure on the stock , will increase SME
funding chain risk.
stone coated metal roofing tile Standardization is the trend
However, the customized
production obviously can not meet the further development of wood industry .
"Custom
doors like a tailored , long period, production of small, a serious impediment
to industrial upgrading and wooden product standardization within the industry
is already a serious problem ." China Forest Products Industry
Association, the relevant responsible person said .
Customized
to specific production line , according to industry calculations, if I can not
standardized doors , an annual production capacity of 10,000 sets of doors
production line, can only produce about 4,000 sets of doors .
With
the housing industry progresses, wooden products, consumer technology, quality
standards and other requirements continue to increase , coupled with the
domestic wood production enterprises expanding degree of the scale ,
standardization doors have become the trend of production and consumption . China
Real Estate Research Association vice president Tongyue Zhong said that the
Chinese market is custom doors by the standard model , capacity and other
aspects of limitations, have not been able to achieve industrialization ,
large-scale , in order to adapt to market development , China wooden door
industry urgent need to achieve standardization, scale
.
And the "
wood windows and doors " introduction of national standards , will
undoubtedly further promote the wood industry towards a more standardized
production of road . It
is understood that the promulgation of the " wooden doors and windows
," the national standard, mainly for the industrial production. "From the
content point of view , this new GB mainly for the doors of businesses ,
large-scale , standardized production will be the future direction of the wood
industry ." Industry analysts pointed out .
Upstream of the construction industry with the
need to
Doors introduction of national
standards , undoubtedly laid the wood industry bigger and stronger foundation .
"
Doors manufacturers are from tailored ' tailor ' transformed into large-scale
production of the modern enterprise ." China Timber Circulation Association
Professional Committee Chairman Zhang Guolin doors also pointed out that if the
size is not uniform architectural openings bottlenecks have been broken , then
the wood industry will actually achieve rapid
development.
China
Forestry Industry Association Working Committee Wu Shengfu doors also said that
as part of a trade before the doors of a cottage , there is no standard
problem, but now industrial production doors , began to highlight this issue ,
" building standards and doors openings standard double doors exacerbated by lack of
industrialization of the difficulty . "
"Full
implementation of standardized production of wooden doors is not currently
practical , because each customer's door opening is not based on a unified
standard design , unless the housing industry really widely practiced ."
An engaged doors sales industry for many years , said the new national standard
doors smoothly performed
mainly lies in the construction industry and the impact on the real
implementation of standards downstream convenience.
However, the market has a
standardized production of new doors . In
the South Third Ring Road in Beijing , a store specializing in wooden doors ,
wooden doors for many years engaged in the sales boss told reporters ,
construction has gradually become standardized interior doors , and generally
have a fixed size , sold his shop is 90 cm wide doors standard doors .
According to statistics , China's annual
completion of Fenestration area are more than 15 million square meters stone
coated steel roofing tile, commodity standard , the variety is also
increasing , and continuously improve quality , skill levels gradually
strengthened , we should say to the construction industry Fenestration industry
has brought a new meteorological .
Recalling
the conduct of aluminum curtain walls and windows , difficult to find, first of
all, aluminum curtain wall aluminum and aluminum kneading is actually an
extension of commodity products , present the majority of the aluminum plant
directly into the sphere of production of aluminum curtain walls and windows , after the phasing out of the mall , part
of the company to become the main production of aluminum curtain walls and
windows .
Second,
with the depth of the construction division of labor to carry out decoration ,
from the construction industry, metal processing industry, specializing in
parting out the production of aluminum curtain walls and windows of the
professional company , to become the main force in industry . These companies
cover aluminum curtain walls skills development , design , manufacture and
installation of the entire process , from the largely extends directly to the
construction of the construction field .
Third , part of the
glass production , processing companies have also entered the aluminum curtain
walls and windows of the industry. While a considerable number of "
storefront factory" active in the aluminum curtain walls and windows of
the mall. Because
such small-scale processing plants , processing skills , of varying quality ,
construction and installation of the level is not high, the whole industry has
brought a certain impact. However,
because of its operating flexibility, able to turn into shopping malls
supplement exist.
stone
coated steel roofing tile Experts pointed out that , since the entire mall aluminum curtain wall
industry supply and demand , the quality is good or bad , skill levels, so
depending on price fluctuations before the three types of companies , and thus
, from a macro perspective, the current domestic primary aluminum curtain wall
industry has the following characteristics .
( A ) occupational sophisticated and
ever- intensifying competition . Compared
to other industrial kneading profile products concerned, because the standard
aluminum curtain walls and windows more fixed , but the accuracy and strength
requirements are not particularly high, aluminum processing plant profiles
kneading skills already quite sophisticated, commodity differences gradually
reduced, resulting competition abnormal intense. From the past two years, aluminum
plant capacity to see the device's overall vacancy rates are in the 40% to 50%.
(
Two ) because aluminum curtain walls bulky commodities , commodity
characteristics of the process of forming long , plus transportation costs, the
impact of tariffs , aluminum curtain wall malls simply a case of regional
shopping malls, the company's business and domestic goods is more than 90% the domestic -oriented shopping malls ,
shopping centers will become in the future to carry out international space .
(
Three ) the specific circumstances from an industrial chain can be seen on the
aluminum curtain walls and windows in the downstream industry association is
more pure , completely dependent on the rise and fall of industrial
construction industry, the shopping malls operated essentially concentrated in
specific risk downstream industries. Thus, the domestic manufacturers in the
construction industry to establish an extensive mall marketing channel is most
important. In addition,
the aluminum industry ( aluminum , aluminum ) , glass industry will be carried
out directly restricts production costs . Thus
the entire production run considerable risk concentration .
( Four ) goods carried relatively few
restrictions . From
metal products industries, the aluminum curtain walls are the ultimate consumer
, unlike commodity parts or accessories, standards set by the customer ;
aluminum curtain wall company only needs to know the quality of life of
consumers' potential needs , we can for aluminum doors and windows curtain
walls structures ,
accessories or making the research and development , which can create many new
improved form or aluminum curtain wall windows . Thus commodities and innovation
skills areas in aluminum curtain wall a lot of space , but also the focus of
competition .
( Five ) foreign aluminum curtain
wall manufacturers have long joined the race. Because
aluminum kneading industrial mall very early joined the international
competition , while standardized curtain wall is introduced from abroad in
recent years, the construction industry in our country flourished, many foreign
trade are strong competitors have entered the Chinese market, so that the
domestic mall more
sophisticated , to the entire industry has brought new skills and management
model , which further improve the mall is very useful .
( Six ) with the Occupational
contest seriously , Loaning amazing , receivables big hurt to carry out . Although
the construction sector Qiandingwanzhu , Loaning allowed , not allowed to
default , but because of commercial competition stringent financing system is
not perfect , the company's strength is relatively small , only " aware of
the tiger , migraine on a difficult path ," the company carried out by compromised. Successful
financing, improve the company's shopping centers can be relatively contest
force . In addition , the
mall disorderly competition is quite fierce , so that the whole industrial
management level is not improved .
Experts
pointed out that , according to the countries planning , the construction
industry has become quite a long period of hot consumer and economic growth
point for China's aluminum curtain walls occupation carried out to provide a
broad mall.
If you look closely , you will find more
and more doors industry brand began to try in different modes gallop stone
coated metal roofing tile market ; rather have a temporary situation
on the market distribution model , and gradually showing its weaknesses .
Traditional distribution
links and more costly wood industry currently uses almost all dealers mode. Generally
followed the same pattern , the local business agent or distributor of a brand
, stationed in a store , distributor or dealer outlets to the store to pay rent
and other fees.
Insiders
said that dealers mode in addition to the production companies expand sales
channels , but also timely feedback of market related information, more
efficient, have some time to promote the rapid development of industry . But with today's industry
profits fell , dealers or agents bear the cost of increasing the old pattern
gradually reflect more disadvantage.
It is understood that 90% of the
wood industry manufacturers are taking dealer mode. However, there are many dealers feel
that the brand is not your own , is "to others her son ." Prior industry is profiteering
era, driven by the interests , there are still a lot of people are willing to
" wedding dress for others ." As the industry into the era of small profits ,
some dealers also heart intended to retire .
Under the weight of the
high-cost , domestic enterprises have to integrate resources , "
self-built channels ." In this regard
, the Nobel tile most right to speak . Nobel
tiles take years to set up branches in major cities a combination of direct and
distribution , according to industry analysts , Direct mode after all channels
of a high-cost era of enterprise development. "Factory to
shop channel , local enterprises are mainly doing maintenance and service , and
perhaps this is a healthier way ." Operated for many years in the
industry, said Mr. Shen . "Factory set up branch offices
, pricing power in the hands of manufacturers to grasp , just close to the
current mode of operation of the appliance .
Today, the doors of businesses have
" shock ." According
to incomplete statistics , Hei Bao dream , TATA doors , Dekor other famous
brands have begun to test the water commerce .
In
TATA doors , for example, the enterprise of a product "to move " up
sales online shopping mall , at the same time more than 800 stores nationwide
network area also opened , allowing the owners to enjoy from the reservation ,
payment to a real one-stop service services.
Two
years ago, local pine furniture leader " hi dream treasure" long
"sea ", the Xiamen area manager , said online sales more than 30%
annual growth rate .
With the
rapid development of Internet , consumer attitudes and the way is undergoing a
huge transformation , stone coated steel
roofing tile online shopping become
their shopping in another way . To
some extent , the doors of industry wading commerce " is Me ."
It is reported that the State announced that 10 million units of affordable housing and shantytowns market.
Countries to develop affordable housing, affordable housing will account for the expected future market share of 50%.
For the protection of housing
construction, stone enterprise initiative
may not be very high, which is currently under the constraints of
the situation of consumption levels
because economic laws determine the profitability of the enterprise. Currently CHINA
MANUFACTURED STONE VENEER
industry is mainly focused on high-end real
estate projects, affordable
housing market is not too much
input, partly because of the particularity
of the stone industry, stone house
building is reflected in the
grade, on the other hand, economic
laws restricted the enterprise
the affordable housing market expansion, if in order to reduce the cost of affordable housing projects in the use of
low-grade stone products, might
as well not.
But as people's living standards and
incomes rise, luxury becomes necessity, the affordable housing
market, the consumption power of the CHINA MANUFACTURED
STONE VENEER was unstoppable in the first quarter
market data also proved
this point to protect the housing
market has the potential spending
power of the stone .
According to official statistics,
the stone used in the main market is the
use of the building, and with the process of urbanization in China will continue to increase. As people's income and consumption levels
increase, the stone will become luxury goods from
the necessities of life, the
pursuit of consumption upgrade
is a trend. Affordable housing market spending power of
the stone is irresistible, in the
first quarter market data also
proved this point to protect the housing market has the potential spending power of the stone.
