Specifications
Heavy (Ground) Calcium Carbonate is widely used as filler and improver.
Purity: 98%min.
Appearance: white powder.
Heavy calcium carbonate, also called ground calcium carbonate, is produced by natural superior calcite, which has high purity and whiteness. The size ranges from under 400 mesh which is called primary products, to 2000 mesh or above, depending on your requirement.
Heavy (Ground) Calcium Carbonate is widely used as filler and improver in plastic, paint, paper-making, rubber, feed, daily chemical, ceramics, adhesives and ink industry.
Function of calcium carbonat
Low heavy metal content, using high-quality natural calcite production, lead and arsenic content can be lower than 0.3, and has no sulfide; Manganese, aluminum, magnesium content is very low, processing for customers.
Certificate
Our factories have achieved ISO Certificate, 23 technologies have obtained national patents.
Application
1. As preservative of wheat, apples, cabbage, dessert and others and food additive.
2. Be used in the production of dyes and dyeing industry: ultrafine active heavy calcium carbonate.
3. As adhesives and sealants: ultrafine active heavy calcium carbonate.
4. Be used in aper industry: superfine heavy calcium carbonate rubber industry.

Light calcium carbonate, another name is precipitated calcium carbonate or precipitated chalkchemical formula is CaCO3. It is made by chemical processing, its volume bysedimentation(2.4-28mL/g)is larger than heavy calcium carbonate(1.1-1.9 ml /g) do, which is produced by mechanical method. At room temperature(25℃) concentration to water shall be 8.7/1029 and the solubility is 0.0014 the pH value shall be 9.5-10.2. Light calcium carbonate is nontoxic odorless, and usually white, with a relative density of 2.7-2.9. it do bag range of application in civil construction and rubber industry and many other business.

Calcium carbonate can be divided into heavy calcium carbonate, light calcium carbonate.
Heavy calcium carbonate is widely used in plastics, rubber, papermaking, coatings, feed, medicine, daily chemicals, glass, ceramics and other fields.
Light calcium carbonate is mainly used as a filler in rubber, plastics, papermaking, coatings, inks and other industries, and can be used in daily chemical products such as tooth powder, toothpaste, cosmetics, etc., and can also be used in organic synthesis, metallurgy, glass and asbestos in production.

The difference between heavy and light calcium
Both calcium carbonate light and calcium carbonate heavy are commonly used as fillers in the coating and plastics industry. The content of the first grade is 99.1% and that of the second grade is 97.9%. The difference between heavy and light calcium carbonate is as follows:
1. The main difference is that light calcium is used for fillers, welding electrodes, organic synthesis, etc. Heavy calcium is used for the production of anhydrous calcium chloride, cement, etc.
2. Ground calcium carbonate or heavy calcium carbonate is calcium carbonate, which is cheap because it is prepared by compressing calcite, and tends to settle when used in emulsioni paint compared with light calcium carbonate.Lightweight calcium carbonate, also known as precipitated calcium carbonate, was found to be progressively smaller in size, larger in oil absorption and higher in price.They are commonly used in latex paint fillers, with the use.
3. Heavy calcium is made by crushing ore, while light calcium is made by artificial synthesis. There is a large amount of coating.
4. Heavy calcium is stable, but relatively light calcium sinks easily.
Light calcium is better in the settlement, but the oil absorption is greater than heavy calcium, the price is generally more expensive than heavy calcium, although the stability is not as good as heavy calcium, but still have stability, even if the external wall paint, its dosage is also very large!
