Package & Storage of Calcium Carbonate:
25KG bag , Light: 18 MT/20'FCL, Dense:20 MT/20'FCL
also be packed according to customer's needs.
Store closed containers in a cool, dry, well-ventilated area. Avoid exposure to direct sunlight.
Applications of Calcium Carbonate:
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 etc.
