Transportation and Storage Safety:
This product, non-toxic harmless, white powder, prevent moisture in the process of transportation, storage should be placed in a cool, ventilated, dry place. Avoid breathing dust when processing, if contamination, can be cleaned with soap and water , concrete technology may refer to the corresponding material safety data.
Powder coatings , difference forms with general coatings, as the micron powders existence. Because not use solvent, to be called powder coatings. The main features: Harmless, high efficiency, saving resources and environmental protection characteristics
Two categories: Thermoplastic Powder Coatings and thermosetting powder coatings.
Thermoplastic powder coatings is made up of thermoplastic resin, pigments, fillers, plasticizer and stabilizer and so on.
Thermoplastic powder coatings: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose, polyester.
Thermosetting powder coating is made of thermosetting resin, curing agent, pigments, fillers and additives, etc.Thermosetting powder coatings: epoxy, polyester, acrylic resin.
Shanghai liang jiang titanium white products co., LTD. , precipitated barium sulfate (special for powder coatings) as a new filler product,The particle size and size distribution is better than conventional precipitated barium and ultrafine barium."Liangjiang" brand - precipitated barium sulfate (special for powder coatings) ,the special surface modification treatment, significantly lower oil absorption, and obviously improve the compatibility of resin, The test for the Coating of boiled and solvent resistance shows that the "liangjiang" brand - precipitated barium sulfate (special for powder coatings ) has the chemical adsorption between polyester resin and epoxy resin, to make the coupling reagent effects, the lower extrusion of the melt temperature, "liangjiang" brand - precipitated barium sulfate (special for powder coatings) significantly improve the processing fluidity, improve productivity and not adhesion between the grains, no reunion phenomenon.
"liangjiang" brand - precipitated barium sulfate (special for powder coatings ) narrow particle size distribution, precision control for the coarse particles (large particles), low oil absorption, surface modification makes some organic, better using in thin coating powders, so that makes a better flow leveling and plumpness.
1.Liangjiang brand- Barium sulfate precipated, using in coatings:
high solid coatings
|Excellent size distribution (0.7μm), can improve the gloss and reduce VOC and the cost of production.|
The crystal structure makes it a good smoothing agent, and can enhance the flat in the coating.With a small oil absorption, high gloss, good covering power, good weather resistance, and low particle size, etc.
|water based coatings||
Due to the chemical inertness and solubility, it also use in water-based coating, especially in the electrophoresis paint.
Special inorganic processes, and other useful properties remain the same, and through the inorganic semiconductor, given the conductive properties via the coating.
|automobile coatings||Barium sulfate can make the pigment steady, prevent flocculation, wear, and has excellent weather resistance and transparency. Used to increase the solids metallic paint, and won't cause color changes;Can also influence or control the flow leveling of sheet metal.|
The main purpose of 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.
5. Liangjiang brand-barium sulfate precipated 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.
6. Liangjiang brand-precipitated production process
There are two types of barium sulfate, precipitation and washing.The natural output is barite, The final products are barite powders crushed by barite and barite sulfate precipitated made by the raw materials of barite through chemical reaction.
Liangjiang brand - barium sulfate precipitated take BaCo3 as raw material, The process is different with the production of precipitated barium sulfate at current market, better whiteness, higher content, more strong dispersibility, we can produce according to customer’s requirements, deeply trust by domestic and foreign enterprises.
we aspires to be the supplier of the world's leading chemical raw materials, show our value of the products made in China!
