Stone does not exist in a vacuum things, in the handling, processing and use of the process will inevitably damage phenomenon cracking. Once the stone is worn it will seriously affect the appearance of its decorative effect. Since this wear is unavoidable, so how should we repair it? This article will briefly explain the method of repair worn stone.
Penetration
Penetration is on the sheet is not ruptured in a separate infusion cracks penetrate rubber, cured after a certain time, to the adhesive, the intensity increased solid sheet of a process.
(Gel permeation recipe: 307 unsaturated resin 100%; styrene 60-100%; cyclohexanone peroxide 4-5%; naphthoic acid 3-4% cobalt.)
Production methods:
(1) unsaturated resin 307 and the styrene ratio by the above uniform harmonic;
(2) then pour peroxide, cyclohexanone and mix well.
(3) and then stir into the cobalt naphthenate. The best penetration of glue is poured glue penetration of glue can penetrate into a linear flow, then the viscosity of the best, the best penetration.
Infiltration process:
(1) Liangshai dry wool board, conditional on strong wind gap can be air-dried, to ensure that no moisture.
(2) with a teaspoon to penetrate along fractures plastic casting, the casting process is best for wool board manufacturing tiny vibrations.
(3) Liangshai sticky glue to penetrate when that is good.
Note:
Unsaturated resin 307 can not directly cyclohexanone peroxide and cobalt naphthenate reconcile, not to cyclohexanone peroxide and cobalt naphthenate separate mixed directly. And should be equipped with a number on how many, or side by side with.
Stone bonding
Adhesive glue preparation: 307 100% unsaturated fat tree; cyclohexanone peroxide slurry 4-5%; naphthoic acid 3-4% cobalt solution. Prepared when the first 307 resin and cyclohexanone peroxide mixture before adding cobalt mixed naphthalene. And in accordance with the number on the need to use much, and the use of time should not exceed 10 minutes.
Bonding operations:
(1) clear ho adhesive surface, so that water, dust-free.
(2) evenly coated with adhesive glue adhesive surface, be careful not too thick.
(3) good adhesive coated immediately after docking, squeezing tightly, so that bonding adhesive slight overflow. And according to the material to choose flat stick or vertical stick. In addition to a small area of ​​the rupture can vigorously for 502 instant glue or adhesive bonding.

Here refers to the finished patch on sand holes, pits, or damage to the corners, and finished with the preparation of a good approximation of the adhesive color to fill an economic process.
stone coated steel roofing tile Repair glue preparation: Epoxy fat 100% (601 or 634); ethylenediamine 8% -10%; and the amount of toner, together with the amount of lithopone, talc filler blended.
Repair operations:
(1) clear ho mend, so mend clean, dry and dry.
(2) with repair glue infill and evenness, and repair glue flow to prevent collapse.
(3) and then curing, curing time is generally 2-4 hours (winter low temperatures may be due 8-10 hours) after bulldozing that is good. Another fact can also be used as a bonding adhesive plus repair glue used toner.
