Calcium carbonate powder milled by the micronizer mill is widely used in the new chemical building materials industry.
With the development of the plastics industry, in recent years, a new type of composite material, calcium-plastic material, has been used as a building material for a large amount of calcium-containing inorganic fillers with a small amount of polyolefin resin and other additives.
This material combines many excellent properties of wood, plastic and paper. It has the characteristics of heat resistance, chemical corrosion resistance, cold resistance, sound insulation, shock resistance and easy processing. It can replace paper and wood in packaging, building materials and pipe fittings. Chemical building materials are light in weight, cheap and easy to process, so they are ideal for doors, windows, ceilings, wall panels, water pipes, stair railings, floors, and electric wires.
Chemical building materials are developing very fast. Some countries in the world have used plastics for building materials to account for 20% to 30% of plastics. Because it can replace steel and wood widely, in today's world, chemical building materials are juxtaposed with steel, wood and cement. "Four big materials."
The chemical building materials are mainly composed of inorganic fillers, and the dosage is extremely large (up to 95%). The general dosage is 30% to 90%. If the polyethylene is crosslinked, the amount of calcium carbonate is 50% to 60%. Polyester resin products such as glass, corrugated board, down pipe, day drain, and calcium carbonate are added to reduce cost, adjust viscosity, and improve processability.
