Artificial stone has a non-toxic, non-radioactive, fire-retardant, non-stick oil, sewage infiltration, Antisepsis, abrasion resistance, impact resistance, easy maintenance, splicing of the advantages of a seamless, any shape, but the prolonged use ofmake the artificial stone wear. Wear artificial stone repair care, mainly to improve the hardness and luster of artificial stone surface. Artificial stone in order to improve the hardness and luster of artificial stone surface, we must first understand the structure of the artificial stone.
Artificial stone is a methyl methacrylate (MMA, the common name acrylic), unsaturated polyester resins (UPR) and other organic polymer material as the substrate, a natural mineral powder, particles as fillers, pigments and other auxiliary agent, after vacuum casting or molding forming polymer composites. Artificial stone basic components are: unsaturated polyester resins, fillers, pigments, accelerators and curing agents. The resin matrix material is the most important man-made stone, in general, the performance of the resin determines the final properties of the artificial stone.
To make artificial stone products have perfect appearance after curing is very important. The so-called post-curing treatment is artificial stone products at a certain temperature, heat a few hours. In general, the strength of the polyester resin curing after ejection is only about 50% of the maximum intensity, need a few weeks or even months to fully cured, and ultimately curing the strength and water resistance of the artificial stone can make a substantial increase. Adopted after the curing process can overcome the shortcomings of the deformation, cracking and improve the surface water resistance, thermal shock resistance, increasing the strength of the matrix resin, will help improve the hardness and luster of the products, and extend the service life. The shortcomings of post-curing cycle is too long, it is recommended to use the most advanced artificial stone surface UV coating process, and instantly you can dry curing.
