Among the following four kinds of artificial marble decorative boards, the polyester type is the most commonly used, with the best physical and chemical properties, easy to design patterns, reproducible, suitable for many 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 boards. The other two production processes are complex and rarely used.

cement type

This kind of artificial marble uses various cements as binders, sand as fine aggregates, crushed marble, granite, industrial waste, etc. as coarse aggregates. Polished and made, commonly known as terrazzo, also known as epoxy floor.

Polyester type

This kind of artificial marble is made of unsaturated polyester as binder, mixed with quartz sand, marble, calcite powder, etc., cast into shape, solidified under the action of curing agent, and processed by demolding, drying, polishing and other processes. production. Our country mostly uses this method to produce artificial marble.

Compound

This artificial marble is composed of inorganic materials and organic polymer materials. After the filler is bonded and formed with inorganic materials, the green body is impregnated in organic monomers to polymerize 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.

Sintered type

This kind of artificial marble is made by mixing feldspar, quartz, pyroxene, calcite powder, hematite powder and a small amount of kaolin, etc., using the mud method to prepare the billet, forming it by semi-dry pressing, and using a high temperature of about 1000 ° C in the kiln. Sintered.
