Calcium carbonate Application:
one)Rubber:
it can lessen the quantity of pricey natural rubber,boost its volume ,reduce fees, Right after including calcium carbonate then can be obtain larger toughness tensile ,tear toughness and abrasion resistance than the pure Rubber vulcanizate
two)Chemical producing components
it is heat-proof, chemical corrosion-proof,cold-proof, anti-noise, shockproof and effortless to procedure. As a result it can be utilised to make doorways, dry motar ,ceilings, wallboard,waterpipe,handrail of stairs,flooring board and electric powered wire,and many others.
3)Painting amp coating:
it is as the filling and as the framework, LaEPT paint far more than 30% quantity are used in thick paint ,26%-60% sum are utilized in water-dependent ache
4)Plastic:
it can boost the quantity of plastics, lessen the fees, enhance the size, security, hardness and tenacity of plastic products.
5)Paperpulp materials:
it can completely make use of its higher whiteness, affinity to h2o and shock intensity, minimal value widely making use of .
six) Coal-fired EPT and EPTed sulfurization
seven)Feed,pharmaceutical industry
making calcium additives, replace the unique shell powEPTto lessen fees.
