Duplication of artificial culture stone ,sometimes the users maybe encountered a warping and cracking, this mainly is the artificial stone resin and filler, pigment, uneven mixing proportion and promoting agent, curing agent and resin is wrong.
In the artificial stone matrix, the resin should be kept in a uniform suspension until the resin is used in the mixture of resins, fillers, pigments, etc. If the packing is suspended in the artificial stone matrix, the bottom of the casting body will result in the difference in the distribution of the filler. Because of the high resin, the solidification shrinkage is more heat and shrinkage; The lower layer resin is less, the curing time will be less hot and less, and the result will be the warp or cracking of the products.
From this, we can get the factors that affect the deformation and cracking of artificial stone:
1. Excessive resin content.
2. Curing is not complete.
3. Or calcium powder board.
4, or use a place with high temperature.
