Net weight: 25 kg/bag
?
Heavy calcium carbonate coarse whiting, which is made of natural calcium carbonate minerals such as calcite, marble grinding. Non-toxic, non-irritating, tasteless, good colour and lustre, high whiteness, small disturbance to the other color, easy coloring, hardness is low, the processing equipment damage light, chemical stability, inert filler, thermal decomposition temperature is above 800 o C, easy drying, moisture is easy to remove, no water of crystallization, and the price is low.
?
4, usage:
?
And heavy calcium carbonate can be divided into ordinary calcium carbonate superfine heavy calcium carbonate, etc. Usually used as a filler, heavy calcium carbonate is widely used in artificial floor tile, rubber, plastic, papermaking, coating, paint, printing ink, cable, construction supplies, food, medicine, daily chemical industry such as textile, feed, toothpaste, as a filling agent rise to increase the volume of products, reduce production costs.
?
1) application in rubber
?
Used in rubber, can increase the volume of the rubber, to improve the rubber processability, half reinforcing or reinforcing effect, and can adjust the hardness of rubber.
?
(2) application in plastic
?
Plastic industry is one of the largest consumption of heavy calcium carbonate, refining the coarse whiting powder, can obviously increase the plastic composites strong strength and mechanical properties of the interface. Plastic is used in fine coarse whiting powder, can reduce the manufacturing cost, but also improve and change its properties.
?
(3) application in papermaking
?
Papermaking industry with heavy calcium carbonate is mainly used for two purposes, one is for packing, 2 it is the coating. At present, our country papermaking process in most paper mills are using the acid method, using packing mainly kaolin and talcum powder, coarse whiting will replace acid type sizing, coarse whiting powder as the filler will replace the talcum powder in large range or high ?soil.
?
(4) application in paint and coatings
?
Paint and coatings is also one of the main consumption of coarse whiting, is commonly used as a filler and physical pigments, mainly the type of application is architectural coatings. Industrial developed countries such as Europe and the United States abroad, adhesive is also one of the main consumption of coarse whiting, but rubber powder of coarse whiting the demand is higher, general requirements fineness of > 1250 mesh. In addition, fine granularity, high purity and good whiteness of heavy calcium carbonate was also used in ink, pharmaceutical, cosmetics and other fields.
?
Main item number: 1250 mesh, 1500 mesh, 2000 mesh, 2500 mesh, 3000 mesh, 4000 mesh, 5000 mesh, 6000 mesh, 7000 mesh, 8000 mesh, 11000 mesh, etc. Porcelain, rubber products, etc. The chemical industry.
