How to make activated calcium carbonate What can calcium carbonate do

Calcium carbonate is an important inorganic mineral. From a geological point of view, calcium carbonate is the natural mineral of the Earth's crust. There are 3 types of calcium carbonate deposits.

The production of paints is another important use of calcium carbonate. Calcium carbonate is an important filler in paint production, and the fineness and particle distribution determine the transparency of the paint.

The main uses of calcium carbonate products.

Rubber industry: Calcium carbonate is one of the most used fillers in the rubber industry. Calcium carbonate is heavily filled in rubber, which can increase the volume of its products and save expensive natural rubber, thereby significantly reducing costs.

Calcium carbonate is added to rubber to obtain higher tensile strength, tear strength and abrasion resistance than pure rubber vulcanos.

Plastic industry: calcium carbonate can play a skeleton role in plastic products, which has a great effect on the dimensional stability of plastic products, and can also improve the hardness of products, and improve the surface gloss and surface flatness of products. Since calcium carbonate white is more than 90%, it also replaces expensive white pigments.

Paint industry: The amount of calcium carbonate in the paint industry is also large, such as more than 30% in thick paint.

Water-based coating industry: calcium carbonate is more widely used in the water-based coating industry, which can make the coating non-sedimentation, easy to disperse, good gloss and other characteristics, and the dosage in water-based paint is 20-60%.

In addition, calcium carbonate plays an important role in the paper industry, which can ensure the strength of the paper and the cost is low. In the cable industry products, it can play a certain insulating role.

Do you know what calcium carbonate is used for?

It should be white lime! Construction, pesticides.

Calcium carbonate is a carbonate compound of carbon, an inorganic compound, and one of many calcium supplements. However, many people think that calcium carbonate is the first generation of calcium supplementation products, and thus belittle its production, which is actually not scientific. Experts from the China Health Care Association said that calcium carbonate is the main ingredient in the calcium supplements eaten by astronauts, and calcium carbonate now occupies a large share in the market.

Calcium deficiency in children will cause anorexia, hyperhidrosis, night terrors, occipital baldness and other symptoms, and severe can lead to chicken breasts, migraines, X-shaped legs, growing pains, and O-shaped legs.

If adolescents are deficient in calcium, they are prone to inattention, irritability, hyperactivity, severe deficiency, heel and calf soreness, developmental delay, short stature, excessive sweating, late tooth change, tooth pain, insufficient milk secretion due to calcium deficiency in pregnant women, cramps, numbness of hands and feet, weakness of limbs, inability to bear weight, and gestational hypertension when severe calcium deficiency occurs. It can be seen that calcium is very important for our human health.

Calcium carbonate is CaCO3, which is a pure trace element with no main components. Moderate consumption is not harmful to the human body. Biological calcium carbonate is a high-quality calcium source refined and extracted from biological raw materials such as oyster shells, with high calcium content, of which the calcium content is 3 times that of calcium lactate and 4 times that of calcium gluconate; It is very easy to be absorbed by the human body, has no peculiar smell, has high biological potency, and is small.

It can be widely used in medicine, food, health products, industry and other industries. In addition to being used as a nutritional fortifier, it can also be used as an alkaline agent, dough regulator or anti-caking agent.

As an important inorganic powder product, calcium carbonate is widely used as a filler in the following industries due to its wide range of raw materials, low processing cost, non-toxicity and high whiteness

1. Rubber: A large amount of calcium carbonate filled in rubber products can increase the volume of the product, thereby saving expensive natural rubber or synthetic rubber and achieving the purpose of reducing costs; Improved processability without affecting the vulcanization system of the rubber due to changes in the addition ratio; Improve the performance of vulcanized rubber, play a reinforcing or semi-reinforcing role; The hardness can be adjusted by varying the amount of calcium carbonate filling; Adjust the viscosity in the latex glue and the glue of the rubber, etc.

2. Plastics: adding calcium carbonate to plastics can play a skeleton role and improve the dimensional stability of plastic products; Improve the hardness and rigidity of plastic products; The addition of calcium carbonate can change the rheological properties of plastics; Improve the surface gloss and surface flatness of products; Reduce the shrinkage, linear expansion coefficient and creep performance of plastic products, which is helpful for the processing and forming of plastics; Improve the heat resistance of plastic products and improve the astigmatism of plastics; Reduce the cost of plastic products.

3. Papermaking: adding a large amount of calcium carbonate to the paper can ensure the strength and whiteness of the paper, and at the same time reduce the cost. Calcium carbonate is used as a white pigment for coatings in coated paper, which has the advantages of high whiteness, can adjust the absorption of ink, and has good hiding power and optical properties.

4. Coating: Calcium carbonate is a filler used in a large number of coatings, which plays a skeleton role. Filling the oil-based paint with calcium carbonate can thicken and thicken the paint, and play a role in filling and leveling.

Calcium carbonate is an ideal matting filler in topcoats; In water-based coatings, calcium carbonate is white, hydrophilic, and cheap, so it has been widely used.

Calcium carbonate also has a large number of applications in medicine, food, feed, ink, toothpaste, cosmetics and other fields. Moreover, with the progress and development of science and technology and the influence of relevant national policies, the use of calcium carbonate will become more and more extensive, and the demand will be more and more.

According to the different fineness of the crushing bai, the industrial DU is divided into four different specifications: single fly, double DAO fly, three fly, and four fly, which are used respectively.

The various ministries of industry are subordinate to the door. Single flying powder: used in the production of anhydrous calcium chloride (CaCl), is an auxiliary raw material for the production of sodium dichromate.

The main raw material for the production of glass and cement. In addition, it is also used in building materials and poultry feed, etc. Double Fly Powder:

It is a raw material for the production of anhydrous calcium chloride and glass, a white filler for rubber and paint, and a building material. Sanfei powder: used as a filler for plastics, paint putty, coatings, plywood and paints.

Four flying powder: used as filler for wire insulation, rubber molded products and filler for asphalt linoleum.
