The use of 400 mesh heavy calcium carbonate in Yuanlei small classroom is worth collecting.

 

According to different regions and production costs, material costs, as well as the whiteness of heavy calcium carbonate powder, 400 mesh heavy calcium carbonate powder prices also vary greatly. Heavy calcium carbonate powder 400 mesh is usually used as a filler, but also widely used in artificial floor tiles, rubber, plastic, paper, paint, ink, cable, construction supplies, food, medicine, textile, feed, toothpaste and other daily chemical industry, as a filler to increase the volume of products, reduce production costs. Used in rubber, it can increase the volume of rubber, improve the processability of rubber, play a semi-reinforcing or reinforcing role, and adjust the hardness of rubber.

 

Heavy calcium carbonate powder 400 mesh application function in various industries:

 

1. Use in coal-fired power plant industry
Limestone flue gas desulfurization is to synthesize calcium sulfite from calcium carbonate and sulfur dioxide produced in the process of coal combustion, and then contact with air to oxidize into gypsum (calcium sulfate), which can effectively reduce the emission of sulfur dioxide from coal-fired power plants by 90%. And the production of desulfurization gypsum products can be sold directly to the cement plant or gypsum board factory. The amount of calcium carbonate desulfurization powder is related to sulfur in coal, usually 40000 tons/year of desulfurization powder for 300000 kilowatts of coal-fired power plants.

 

2. Use in putty coatings

 

Heavy calcium powder used in putty coating is mainly to reduce costs, improve hardness, used as the main filler, the general requirements of heavy calcium powder 400 to 325 mesh, whiteness of not less than 80%.

 

3. Use in the feed industry
The heavy calcium powder used in the feed industry requires that the fineness of the heavy calcium powder is 325 mesh, the whiteness requirement is 95%, the calcium carbonate content is 99%, and it is pure and free of impurities. Calcium carbonate can increase the calcium content in the feed and improve the feed quality.

 

4. Use in floor tile industry
Heavy calcium carbonate (heavy calcium powder) for floor tiles: 400 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5, (pure without impurities) calcium carbonate can be used in floor tile industry to increase whiteness and tensile force of products, improve toughness of products and reduce production costs.

 

5. Use in the paper industry
Heavy calcium carbonate (heavy calcium powder) for papermaking requires that the fineness of heavy calcium powder is not less than 325 mesh, whiteness requirement is 95%, and calcium carbonate content is 98%. Calcium carbonate plays an important role in papermaking industry. It can ensure the strength and whiteness of the paper, and the cost is low.

 

6. Use of filler in papermaking
Modified calcium carbonate coated with starch is used as filler for papermaking. Whiteness requirement: 95%. Calcium carbonate content: 98%. Calcium carbonate plays an important role in the paper industry, which can ensure the strength and whiteness of paper, and the cost is low.

 

7. Use in the rubber industry
Heavy calcium carbonate powder for rubber: 400 mesh, whiteness: 93%, calcium carbonate: 96%, calcium carbonate is one of the most widely used fillers in rubber industry. A large amount of calcium carbonate is filled in rubber, which can increase the volume of its products and save expensive natural rubber, thereby greatly reducing costs. Calcium carbonate is filled into rubber, which can obtain higher tensile strength, tear strength and abrasion resistance than pure rubber sulfide.

 

8. Use in the artificial marble industry

Heavy calcium carbonate (heavy calcium powder) for artificial marble: heavy calcium powder is required to have a fine bottom of 325 mesh to 400 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5, (pure without impurities) calcium carbonate has been widely used in artificial marble production.
