Artificial stone production process
Analysis of the production and development prospects of artificial stone solid surface materials
The artificial stone is made of resin as binder, combined with natural marble or inorganic mineral powder such as calcite, dolomite, silica sand, glass powder, etc., and appropriate amount of flame retardant, stabilizer, pigment, etc., mixed by ingredients, cast, vacuum An artificial stone made by molding, polishing and polishing.
The solid surface artificial stone has a smooth surface, beautiful color and certain transparency; it has sufficient strength, rigidity, hardness, impact resistance and scratch resistance; weathering resistance, deformation resistance and rapid cooling and quenching; Solid from the bottom to the surface, no pores, no dirt, easy to clean, long-lasting; seamlessly stitched, smooth and smooth surface; heat-resistant, cold-resistant, corrosion-resistant; can be cut and heated to bend, shape different shape. The artificial stone retains the noble and elegant temperament of natural stone, overcomes the defects of capillary pores, cracks, chromatic aberration and radioactivity which are common in natural stone, and quickly becomes an internationally popular high-grade environmental protection decorative material. Solid surface materials can be divided into two categories: acrylic (pmma) and unsaturated polyester (upr) according to the matrix material. The domestic enterprises generally produce upr. The upr solid surface material is made of unsaturated polyester resin and aluminum hydroxide or calcium carbonate powder. The production process is flat casting. Its production process control points:
1 resin and filler mix and mixing effect;
2 gel time control;
3 vacuum bubble effect;
4 curing temperature and time control;
5 post-processing technology. Production and development prospects of artificial stone solid surface materials In the molding process of stone, the most important and basic molding process is the curing of resin, the process of resin changing from liquid to solid, this process can be completed without pressure and normal temperature. From the chemical point of view, it is the process of transforming from a linear structure to a bulk structure. After the curing reaction of the resin, the liquid resin becomes a solid body structure, insoluble and infusible crosslinked copolymer, and has a certain strength, hardness and toughness.
