Filler masterbatch calcium carbonate
Features:
High whiteness ,fine grain size,low impurity, adopting dry surface treatment tech
?
Precipitated?Calcium Carbonate?selects high?purity limestone as rawmaterial, is made through process of calcining.
?
chemical reaction, reselection. dehydration, drying?and depolymerization. It is adopted the technics of particular multi-
?
selection and secondary depolymerization.
?
CaCo3?is widely used int rubber, plastic, paper making, painting ink and so on. To reduce?the cost of products,?to
?
make products have good formed?effect. To enhance hardness, rigidity, size stablity, and glossiness of products.
?
Mainly Applications:
?
1.??In rubber manufacture:?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 also enhance the?tensile strength, abrasion and tearing strength.
?
2.??Plastic manufacture: As the framwork in plastic products, keeping stablity of the products,??strengthen the
?
products, keeing surface smoothly, Since the calcium carbonate is hight white, it?can place the expensive the white
?
ployethylene, for whitening the plastic products.
?
3.? Paper making: Whitening the paper, and as the fller, can reducing the pulp, for saving the cost.:
?
Feathures : Hight whiteness ,fine grain size, low impurity, adopting dry surface treatment technique, with high
?
activation rate.
