Coating general knowledge: nano photocatalytic exterior wall coating (emulsion paint) (5)

The main results are as follows: (1) preparation of nano photocatalytic slurry In the preparation process of active zinc oxide, 1.25% palladium chloride, 1.25% platinum oxide, 1.25% ruthenium chloride, 1.25% silver nitrate (calculated according to the total amount of nano photocatalytic materials) were added to prepare the complex solution, and nano photocatalytic materials with a particle size of 200-500nm were prepared The nano photocatalytic material / polyacetate dispersant and deionized water were mixed at the ratio of 40:5:55 and dispersed by high shear disperser for 1h, so that the fineness of scraper slurry was less than 10 μ M (2) preparation of nano photocatalytic emulsion slurry Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Home of coatings: (1) in the preparation of active zinc oxide from nano photocatalytic slurry, 1.25% palladium chloride, 1.25% platinum oxide, 1.25% ruthenium chloride, 1.25% silver nitrate (based on the total amount of nano photocatalytic materials) are added to prepare the complex solution, and the particle size is 200-500nm Nano photocatalytic materials / polyacid salt dispersant and deionized water were mixed by 40:5:55, and 1H was dispersed by high shear dispersing machine The fineness of scraper slurry was less than 10 m (2) Nano photocatalytic emulsion slurry was prepared by mixing rice photocatalytic slurry, fluorocarbon emulsion and deionized water according to 10: 10: 80 mixing, dispersing by vacuum dispersing machine, vacuum degree 0.05MPa, time 2h, temperature 45-55 C, preparation of nano photocatalytic emulsion slurry (3) Preparation of nano photocatalytic pigment and filler slurry Weigh and mix heavy calcium (1250 mesh), aluminum silicate (1250 mesh), talcum powder, iron dioxide, kaolin (800 mesh), poly acid salt dispersant, modified silicone oil defoamer, glycol, glycol butyl ether, carboxymethylcellulose, deionized water according to 15:15:10:5:5:2:1:2.5:2.5:2:30, disperse for 2h with high shear disperser, sand grind for 1H, make the fineness of slurry scraper less than 30 μ m, and prepare Forming nano photocatalysis pigment and filler slurry (4) coating preparation of nano photocatalytic emulsion slurry, nano photocatalyst, filling slurry, deionized water, according to 10:80:10 weighing mixing Use vacuum homogenizer to disperse for 2h, filter and pack The product has good antibacterial property and photocatalytic degradation Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
