Nanoscale ultrafine barium sulfate

详情

Nanoscale ultrafine barium sulfate has the strong chemical inertness, good stability, acid and alkali resistance, moderate hardness, high whiteness, high gloss, can absorb harmful x and gamma rays, is a kind of environmentally functional materials.Nu-lax group after several scientific research institutions to research and development of new achievements, with high and new science and technology, nanotechnology research and development and production of modified precipitated barium sulfate.


Ultra small particle size
With a narrow particle size distribution, particle size controllable. Particle size is in commonly 0.3 0.5 UM. So low oil absorption, good gloss, can effectively reduce the VOC content, at the same time can be prepared into thin coating products, processing and good stability, etc.With lower cost and protect the environment.To adopt new technology, the product small particle size, narrow distribution range, good chemical stability, high purity, good weather resistance, high degree of activation, good dispersibility, high whiteness characteristics.
Super whiteness
Nanoscale ultrafine barium sulfate has the ultra high whiteness, barium content is higher than that of more than *9.5, so has high purity, good weather resistance, acid and alkali resistance, good water resistance, etc.Maintain neutral color, color difference will not affect the downstream products, ensure the stability of the color. 
  
Super good dispersibility
 
Nanoscale ultrafine barium sulfate with special surface treatment, has the very good dispersibility, scraper fineness can reach 5 microns below, so using modified coating, high gloss and thixotropy, dispersing pigments can help at the same time, reduce the dosage of pigment, shorten the grinding time and cost savings.
Six major characteristics
First: the activation degree is high, good dispersibility, and resin has the good affinity, increase the rate of on powder, can be used exclusively for thin coating.
The second: low oil absorption, reduce the dosage of matrix resin, has the very good flow property.
Third: high purity, good acid and alkali resistance, weather resistance, high temperature resistant and do not break light, reduce color degeneration.
Fourth: good dispersion, with spatial isolation effect, can reduce the dosage of pigment such as titanium dioxide.
Fifth: particle size is small, can improve the adhesion, keep the products in all kinds of mechanical properties.
Sixth: less impurities, no harmful substances, can guarantee the safety of products and the surface clean
Scope of application: widely used in all kinds of paint (water-based, oily and powder coating. Automotive paint, wood paint, exterior wall paint, anti-corrosion paint, specular paint, electronic ink, printing ink, etc.). The modified plastics (PA, PBT, PET, PC, POM, PMMA, PP, ABS, PE, PS, plastic, household appliances shell, film, building materials, plastic, etc.), rubber, elastomers, papermaking, cosmetics packing.
Use: can significantly improve product surface gloss, acid and alkali, flowing property, hardness, impact resistance, adhesion and reduce the cost.
Packaging and storage methods: general is *5 kg/bag.Should be stored in a cool, dry, dark place, avoid by all means be affected with damp be affected with damp.
