Description:

 

1. Liangjiang brand- Modified superfine barium sulfate precipitated, using in coatings:

 

The main purpose of Modified superfine barium sulfate precipitated is used in paints and coatings, the domestic paint industry has gained rapid development, the global paint coating increased by 3.9% in 2014, sales reached 43.38 million tons, the sales of architectural coatings is 21.69 million tons, 50% of the total industry sales, industrial paint sales of 12.5802 million tons, 29% of the total industry sales, Barium sulfate is one of the essential raw materials in coatings, used as filling material which can reduce the cost of coating production, and filled with precipitated barium sulfate, production performance is stable, can increase the hardness, wear resistance, sunlight resistance, can replace some parts of titanium dioxide.

 

2. Liangjiang brand-Modified superfine barium sulfate precipitated used in art paint areas

 

Barium sulfate precipitated as the white filler used in great quantities for art paints, addition amount of 30% in the total solids, in yellow, white, dosage of 80% ~ 90%, water 15%, require barium sulfate whiteness stability, pH value is less than 8, no mechanical impurities, no sense of particles. As a filling material, also cover and lighten the effect, can significantly reduce the production cost of art paint.

 

3. Liangjiang brand- Modified superfine barium sulfate precipitated used in rubbers, plastics industry:

Rubber and plastic industry has been developing rapidly in recent years.Rubber domestic and abroad, in short supply, the plastic in the field of chemical building materials (such as alien, plastic window, pipes, etc.) have broad market prospects.Density of barium sulfate precipitated, can increase the products weight, reduce production costs, increase sales revenue.More suitable as the filler for production of rubber sheet packing.It is easy to be mixed in the production processing and molding.

In hard plastic products, barium sulfate precipitated as a filler, the amount of using is bigger, barium sulfate precipitated is added into PVC hard products which can reduce the cost of plastic products, replace titanium dioxide or other pigments in common plastic, can reduce the amount of the added pigments.And the lubrication can increase the stability of the products.

 Barium sulfate precipitated was applied into PP, to make the PP surface like ABS, and shall not affect the PP, with special features, the high glossiness and high surface hardness.

Adopting Modified superfine barium sulfate precipitated of high filling ratio into the production of plastic products, used in the drains, the speakers, the sounds can effectively isolate noise, noise;Used in the curtains, which can increase weight;Used in home appliances shell, which can obtain high glossiness, good color, scratch resistance, good size stability, etc.

Used in the production of the transparent PE film, under the condition of high fill ratio,it will not affect the transmission of light.

 

Masterbatch: Contributes to improve the dispersion of pigment, the phenomenon of lower condensation or flocculation, high filling will not affect the color of pigments.

 

Engineering/modified plastics, it can improve the rigidity of plastic products, hardness and wear resistance, aging resistance,it can help to shorten the cycle of plastic injection molding, also can increase the crystallinity of thermoplastic polymer.

 

General plastic: excellent hiding power, and can get the bright colors with pigments, and make the perfect color and high glossiness for product surface, and has good mechanical properties and wear resistance.

 

Elastomer: High chemical purity, not contain harmful substances, not affects the storage stability and aging resistance.Rubber: can enhance product ageing resistance and weatherability, It is not easy for the products to become fragile as aging, and can significantly improve the surface roughness and hardness of the products.

 

4. Liangjiang brand- Modified superfine barium sulfate precipitated used in papers makings:

Barium sulfate precipated is mainly used in the surface of productions as coating agents, as the only essential raw materials, plus the amount of 5% ~ 15%.The advantages :high whiteness, strong hiding power, much better than that of activated clay and calcium sulfate.

China is the first production of barium sulfate precipitated powers, with rich resources and mature production technology, we can provide different customers with different requirements of products, to meet customer’s demands.
