calcium carbonate Characteristics
White powder, non-toXiHu (West Lake) Dis.c, odorless, non-irritating, non-flamable, non-explosive, minimal refractive index, easy to shade, insoluble in h2o, stable in air.
calcium carbonate Application:
Rubber market
Calcium carbonate is one of the earliest and greatest bulk fillers employed in the rubber market. Calcium carbonate is filled in rubber in huge quantities, which can increase the quantity of the product, therefore conserving high-priced organic rubber and minimizing fees. Calcium carbonate can be acquired by filling rubber. It has larger tensile strength, tear strength, and stronger reinforcing influence in natural rubber and synthetic rubber than pure rubber sulfide, and can alter the regularity.
Plastic industry
Calcium carbonate can engage in a skeEPTn role in plastic items, has a wonderful result on the dimensional stability of plastic merchandise, can increase the hardness of the items, and can also enhance the surface gloss and area flatness of the goods. The addition of calcium carbonate to EPT plastic products can enhance the heat resistance. Considering that the whiteness of calcium carbonate is previously mentioned 90%, it can also substitute the expensive white pigment to achieve a particular whitening effect.
Paint business
Calcium carbonate is a huge amount in the paint business, and it is an indispensable skeEPTn. The volume of the calcium carbonate is far more than thirty% in the thick paint, and the phenolic enamel paint is a lot more than 39% of the phenolic wonderful sample wrinkle paint.
Waterborne coating sector
In the waterborne coating sector, the software is a lot more broadly used, and the coating can be manufactured without sedimentation, effortless to disperse, and has good gloss. The sum of the waterborne coating is 20-sixty%.

Weighty (Floor) Calcium Carbonate is broadly employed as filler and improver.
Purity: ninety eight%min.
Look: white powder.
Heavy calcium carbonate, also referred to as floor calcium carbonate, is created by normal outstanding calcite, which has large purity and whiteness. The size ranges from unEPT400 mesh which is named primary products, to 2000 mesh or over, based on your requirement.
Hefty (Floor) Calcium Carbonate is extensively used as filler and improver in plastic, paint, paper-creating, rubber, pharmacy, feed, every day chemical, ceramics, adhesives and ink industry.

Calcium carbonate Application:
one)Rubber:
it can reduce the amount of costly normal rubber,boost its volume ,minimize charges, Right after adding calcium carbonate then can be get larger power tensile ,tear strength and abrasion resistance than the pure Rubber vulcanizate
two)Chemical production supplies
it is heat-proof, chemical corrosion-proof,cold-evidence, anti-sounds, shockproof and easy to method. Therefore it can be used to make doors, dry motar ,ceilings, wallboard,waterpipe,handrail of stairs,ground board and electric wire,and so forth.
3)Portray amp coating:
it is as the filling and as the framework, LaEPT paint more than thirty% volume are used in thick paint ,26%-sixty% sum are utilised in h2o-based soreness
four)Plastic:
it can boost the volume of plastics, minimize the charges, boost the dimension, security, hardness and tenacity of plastic products.
five)Paperpulp materials:
it can completely make use of its high whiteness, affinity to drinking water and shock intensity, minimal expense widely employing .
six) Coal-fired EPT and EPTed sulfurization
7)Feed,pharmaceutical industry
generating calcium additives, substitute the first shell powEPTto lessen costs.
