Features:
Calcium carbonate can be used in plastic,rubber,paper and paint industries,It has the characters of low price, high purity,difficult to have chemical reaction,good heat resistance,low oil absorption and nontoxic.
( can be using in Detergent industry,Soap industry, Foam Industry,etc , as a filler and save the cost );
Calcium carbonate is widely applied in plastics industry, PVC pipe and cable writing, papermaking and coating and paint and ink, adhesive, toothpaste, high-grade ceramic tile, artifical marble, leather, food, medicine and comestics industries
Application:
1: In rubber industry: calcium carbonate was the earliest filler used in the rubber industry,it can enlarge the capacity in the rubber products,for saving the cost,It aslo enhances the tensile strength,abrasion and tearing strength.
2:In plastic industry: as the framework in plastic products(pvc pipes,fittings,panels,color master batch),keeping stability of the products,strengthen the products,keeping surface smoothly,since the calcium carbonate is high white,it can place the expensive the white polyethylene,for whitening the plastic products.
3:In coating industry: calcium carbonate can be used as white pigment,up a frame function,calcium carbonate in the coating industry can be used as inert pigment,Due to the calcium carbonate color is white,in coating relative latex,solvent prices are cheap,and fine grain,can in coating evenly dispersed,so is a lot of use of inert pigment,Calcium carbonate filling can enhance primer to basic level surface sedimentary and permeability.
4:In paper making: whitening the paper,and as the filler, can reducing the pulp,for saving the cost.
