With the development of modern architecture, decorative materials made of lightweight, high strength, beauty and variety of requirements. Artificial decorative stone is in this situation to arise. It is light weight, high strength, corrosion resistance, pollution, construction convenient, patterns can be artificially controlled, is an ideal modern building decoration materials. Artificial Marble raw materials used by manufacturing and production process, and can be divided into four categories:
(1) cement the artificial marble, artificial marble is a variety of cement as a binder and sand as fine aggregate, crushed marble, granite, industrial waste and other coarse aggregate, the ingredients, mixing, forming, add pressure steam curing, grinding, polishing and made, commonly known as terrazzo.
(2) Polyester artificial marble artificial marble which is unsaturated polyester as binder, and quartz sand, marble, calcite powder mixing, casting molding, under the action of the curing agent curing effect, by stripping , drying, polishing and other processes and made. More this method of production of artificial marble. Unsaturated polyester, good gloss, light color, adjustable into different distinct colors, this low viscosity resin, easy to shape, fast curing, curing at room temperature.
(3) compound Marble Slab artificial marble is that inorganic materials and organic polymer composite composition. Bonding with inorganic materials after forming the filling, then green body immersed in the organic monomer, polymerization under certain conditions it. On the plate, the bottom with a low and stable inorganic material, the surface layer made of polyester and marble powder.
(4) sintering the artificial marble, artificial marble is feldspar, quartz, pyroxene ", calcite powder and red iron ore and a small amount of kaolin mixed with slurry prepared stock, with semi-pressure molding, in the kiln furnace using high temperature of about 1000 C sintering.
The four Artificial marble decorative plates, the most commonly used polyester, its physical and chemical properties of the best, easy to design patterns, a reproducible, suitable for many uses, but the price is relatively high; cement least expensive, but corrosion resistance is poor, prone to cracks, only suitable for the plate. Two other complex production process, apply very little.
Polyester artificial Marble Tile (often referred to as artificial marble) is imitation marble surface texture processed, have similar characteristics of the mechanism of marble, and designer of self-control patterns can be determined with good reproducibility; and Artificial marble and light weight (25% lighter than the natural marble or so), high strength, thin, good corrosion resistance, anti-pollution and better machinability, can be made curved, surfaces and other shapes to facilitate construction. High-quality physical and mechanical properties of artificial marble can be equal to or better than natural marble. However, less than the natural color and texture of natural marble, beautiful and soft.
The impact of raw materials for artificial marble, and many outdoor works for artificial marble is not ideal. Mainly is aging fast, color changes, brightness changes, use the period of time, decorative panels to serious distortion to the upturned corners, and some projects had to use expansion bolts to secure it. Therefore, the artificial marble should not be a large area for outdoor cylinder can be used for outdoor, facade decoration, but when the application height of more than 1.2m pieces of steel wire or stainless steel fastened.
Artificial marble floors and walls can be used for indoor decoration, but also the production of sanitary engineering students, such as wash basin, bath, toilet and so on. In addition, the artificial marble can also be used to make crafts, such as imitation stone carving, jade carving products, etc., for indoor decoration.
