Description: 

1. The fine particles of micronized barium sulfate completely remain the original crystalline structure of BaSO4when the average particle size (D50) is only 1.5um. The specific curface area, surface atomic number and surface atomicity are enormous, thus the hiding capability, the attraction, the dispersibility,the fluidity and optical prosperities have great changes, which absolutely exceed the original fine properties of barium sulfate, and it becomes an outstanding pigment extender.
The fine particles of “Liangjiang brand”micronized barium sulfate have a good scattering and hiding capability, and as a carrier of pigment, it can make the pigment highly decentralized and provide an even color; high whiteness can make the coating clearer and purer; special crystal structure and high refractive index can make the color rich and full.
“Liangjiang brand”micronized barium sulfate has a good chemical inertness, which renders it a better compatibility and makes it easy to organic composite with other materials and enhance the bonding; the suspension system is very stable and never produce flocculation or precipitation.
The surface of “Liangjiang brand”micronized barium sulfate can make the coating film bond with the substrate more strongly; uniform submicron fine particles can make the coating film flatter and smoother and then more robust and durable.
The good chemical inertness, acid resistance, hightemperature resistance and other special properties of “Liangjiang brand”micronized barium sulfate greatly improves the weather ability of coating.
Low oil absorption of “Liangjiang brand”micronized barium sulfate can increase the critical volume concentration of coating and save more resin base materials, so using “Liangjiang brand”.

2. Liangjiang brand Micronized barium sulfate production process:
 

 
 
 1. paint, paint production of barium sulfate characteristics requirements.
 

 
Barium sulfate as an extender pigment is widely used in paint, plays a very important role to improve the coating's thickness, abrasion resistance, water resistance, heat resistance, surface hardness, resistance to impact etc.. In addition, barium sulfate in the wavelength range of 300~400Lm have very high reflective, can protect the film from photoaging, is an effective and inexpensive inorganic white light stabilizer.
Using special technology is made of super fine barium sulfate has many other similar products do not have the characteristics. The acicular crystal structure make it become good flatting agent, and can enhance the coating leveling. It can be used for self clean coatings were used as reinforcing agent; due to the low amount of the oil suction, high filler content, so can decrease the cost of coating can be used for water paint, primer, intermediate coat, oil paint. Use it to replace the water paint in 10% ~ 25% of titanium dioxide. The results improve the whiteness, hiding power did not decline.

2. Liangjiang Brand ultrafine barium sulfate in other areas of application:

  Adhesive: good rheological property, high filling and chemical resistance, make barium sulfate is suitable for adhesive, unsaturated polyester and polyurethane system, etc.

  Printing ink: low wear resistance, high gloss and color stability, low coherence, and combined with its easy liquidity makes barite powder is suitable for the high quality of printing inks, barium sulfate recommended for people with high optical activity of ink.Wood and paint: ultrafine barium sulfate with low coherence, optical characteristics of low dispersion and fine particles, especially suitable for paint paint, varnish, paint, etc. According to the barium sulfate has the chemical resistance and weatherability.

  High fill paint and thick slurry coating: coating series can be applied to all, for example, primer, high build coating all types, such as its low specific surface area and particle size of division and easy mobility, make ultra-fine barium sulfate in the machining process has low wear resistance, ultra-fine barium sulfate recommended for primer surface automatically, even when the high fill also keep a good uniformity and smoothness.

  Paint: ultrafine barium sulfate is better than that of most other filling agent, especially in chemical resistance coating. Its inertia, insoluble in water, acid, alkali and organic agents. Excellent gloss and granular precision makes the paint in long-term exposure can be protected. Ultrafine barium sulfate recommended for paint, it can increase the surface hardness, color stability.

  Road construction: rubber and asphalt mixture containing about 10% ultrafine barium sulfate has been successfully used in the parking lot, is a kind of durable paving material.At present, the heavy road construction equipment tires have been partially filled with ultra-fine barium sulfate, to increase the weight, to consolidate fill region.Prevent ray: cement, mortar and concrete with X-ray absorption performance, made with ultrafine barium sulfate barium cement, mortar and concrete, to replace the metal lead plate shielding nuclear reactors and prevent X ray to build the scientific research, hospital buildings.

  Glass: deoxidation agent, clarifying agent, flux, increase the stability of optical glass, gloss, and strength.

 
Because professional, so we do better!
 
 we aspires to be the world's leading chemical raw materials supply service, the value of that made in China should have!
