The artificial marble is made of natural marble or granite gravel, which is made of cement, gypsum and unsaturated polyester resin as a binder, and is formed by stirring, grinding and polishing.
Cement type artificial marble
The artificial marble is made of various cements as binders, sand is fine aggregate, crushed marble, granite, industrial waste residue, etc. are coarse aggregates, which are compounded, stirred, formed, pressurized and steamed, polished, Made by polishing, commonly known as terrazzo.
Polyester artificial marble
The artificial marble is made of unsaturated polyester as a binder, stirred and mixed with quartz sand, marble, calcite powder, etc., cast and formed, and solidified under the action of a curing agent, and is subjected to processes such as demolding, drying and polishing. production. China uses this method to produce artificial marble.
(often referred to as artificial marble) is made by mimicking the surface texture of marble. It has the characteristics of marble-like mechanism, and the pattern can be controlled by the designer and has good reproducibility. Moreover, the artificial marble is light in weight, high in strength and thin in thickness. It has good corrosion resistance, anti-pollution, and good processability. It can be made into curved shape, curved surface and other shapes, and it is convenient to construct.
Composite artificial marble
The artificial marble is composed of an inorganic material and an organic polymer material. After the filler is bonded and formed by an inorganic material, the green body is immersed in an organic monomer to be polymerized under certain conditions. For the board, the bottom layer is made of an inexpensive and stable inorganic material, and the top layer is made of polyester and marble powder.
Sintered artificial marble
The artificial marble is a mixture of feldspar, quartz, pyroxene, calcite powder and hematite powder and a small amount of kaolin. The billet is prepared by a mud method and formed by a semi-dry pressing method, and a high temperature of about 1000 ° C is used in the kiln. Sintered.
Among the above four artificial marble decorative panels, the most commonly used polyester type, the physical and chemical properties are the best, the pattern is easy to design, reproducible, suitable for a variety of purposes, but the price is relatively high; cement type is the cheapest, but Corrosion resistance is poor, microcracks are prone to occur, and it is only suitable for sheet metal. The other two production processes are complex and have few applications.
