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.
