High-end life is already the driving force for people to travel to various cities. The ultimate goal is to have a foothold in this city. If you have a home, you must decorate it. With the development of modern construction, the decoration materials have been lightened. The requirements of quality, high strength, beauty, and variety of artificial marble materials have emerged in this situation.
It is light weight, high strength, corrosion resistance, pollution resistance, convenient construction, and the patterns can be controlled manually. It is an ideal decoration material for modern buildings. Artificial marble is made of natural marble or granite crushed stone as filler, cement, gypsum and unsaturated polyester resin as adhesive, and it is made after stirring, forming, grinding and polishing. Therefore, artificial marble has many characteristics of natural marble. For example, because artificial marble can be adjusted manually, it has a variety of colors, good flexibility, unobvious connection treatment, very strong overall feeling, and colorful, with ceramic gloss, high surface hardness, not easy to damage, corrosion resistance, and high temperature resistance. And it is very easy to clean. But there is also a big shortcoming, which can cause significant damage to the human body.
Artificial marble classification
At present, there are generally four kinds of artificial marbles commonly used in the market: cement artificial marble, polyester artificial marble, composite artificial marble, and sintered artificial marble.
Among them, the polyester type is the most commonly used, with the best physical and chemical properties, easy to design patterns, reproducible, suitable for multiple purposes, but the price is relatively high. The cement type is the cheapest, but it has poor corrosion resistance and is prone to micro-cracks, so it is only suitable for board. The other two production processes are complex and have few applications.
This kind of artificial marble uses various cements as binders, sand as fine aggregates, and crushed marble, granite, industrial waste residues, etc. as coarse aggregates. After batching, mixing, molding, pressure steam curing, polishing, It is made by polishing, commonly known as terrazzo or epoxy floor.
This kind of artificial marble uses unsaturated polyester as the binder, stirs and mixes with quartz sand, marble, calcite powder, etc., and is cast into a shape. It is cured under the action of a curing agent, and is processed by demoulding, drying, and polishing. production. my country uses this method to produce artificial marble.
This artificial marble is composed of inorganic materials and organic polymer materials. After the filler is bonded and molded with inorganic materials, the green body is then immersed in organic monomer to polymerize it under certain conditions. For the board, the bottom layer is made of cheap and stable inorganic materials, and the surface layer is made of polyester and marble powder.
This kind of artificial marble is mixed with feldspar, quartz, pyroxene, calcite powder and hematite powder and a small amount of kaolin. The billet is prepared by the slurry method, and it is formed by the semi-dry pressing method. The high temperature of about 1000℃ is used in the kiln. Sintered.
