What is artificial stone? What are the types of
Artificial stone is unsaturated polyester resin as binder, with natural marble or calcite, dolomite, silica sand, glass powder and other inorganic powder, as well as the amount of flame retardants, color, etc., by mixing ingredients, porcelain casting, Vibration compression, extrusion and other methods made of curing.
Polyester-type artificial stone Polyester-type artificial stone is unsaturated polyester as binder, and natural marble, granite, quartz sand, calcite powder and admixture mixing, at room temperature consolidation molding, and then stripping And polished after making an artificial stone. Polyester artificial stone is imitated marble, granite surface texture processing, with a similar marble, granite mechanism characteristics, uniform color, compact structure, this ground wear, water, cold, heat. The physical and mechanical properties of high-quality polyester-type artificial stone are equal to or better than natural marble, but the natural and natural color of natural stone is soft and soft, and the physical and mechanical properties of polyester-type artificial marble are as follows: Performance Item Index Relative density (Kg / m3) 2100 Compressive strength (Mpa)> 100 Flexural strength (Mpa)> 30 Impact strength (j / cn2)> 20 Surface hardness (HS)> 35 Surface gloss (degree)> 80 to 100 Water absorption (%) <0.1 Linear expansion coefficient (X100-6) 2 ~ 3
Among the four methods of making artificial marble, the most commonly used polyester artificial marble has the best physical and chemical properties, the pattern is easy to design, reproducible, suitable for a variety of uses, but the price is absolutely high; cement Type of artificial marble the lowest price, but poor corrosion resistance, easy to show micro-cracks, suitable for the plate and not suitable for sanitary ware; compound type is the combination of the strengths of the former two, both good physical and chemical properties, capital But also low; sintered artificial marble, although only clay as adhesive, but subject to high temperature roasting, so energy consumption, high cost, and high product breakage rate.
Artificial marble is divided into: cement-type artificial marble, resin-type artificial marble, composite artificial marble, sintered artificial marble.
