Calcium Carbonate
Calcium Carbonate Description
Activity and Heavy Quality Calcium Carbonate was made use of the best calcite and through process and complex deal with. The surface is 20 times bigger than the common heavy quality calcium. The solubility is about 30 times higher than the common heavy quality. It is white powder and can not dissolve in water, but it easily dissolve in colophony and high polymer. It can dissolve in colophony. The refractive index is the same with the plastic. It is easy to add color. It can improve the flexibility, the intension, the stability of the plastic product. It can improve the process capability, fluid capability, physics machine capability and enhance the mechanics intension. It can reduce the damage of the tools if increase the product.
The chemical index of the product: CaCO3:＞98%,MgO: ≥0.2%,iron:＜0.001%. The capability of abstract oil: (ML／100g）13.4％, PH（100／suspend liquid）：9.0.Hydrochloric acid<0.13%. the degree of white is above 96%. The specific gravity:2.72 Surface: （cm2／g）10000. The quantity of bake<45%
The granularity is equality. The specification is between 400mesh to 5000mesh.
The activity and heavy quality calcium carbonate powder can use as padding. It can increase the flow speed. In addition, it can reduce the cost of the product and enhance the characteristic of the material because it can dissolve organic material. This product is the best choice for plastic field. The activity and thin and heavy quality calcium carbonate in the PVC can replace the active and light calcium, and then enhance the quality of the product and reduce the cost.
The activity and heavy quality calcium carbonate is used in different fields, such as dope, rubber, paper making, plastic and so on.
