Coating general knowledge: nano photocatalytic exterior wall coating (emulsion paint) (6)

Core tip: preparation of nano photocatalytic solution (1) In the preparation process of active zinc oxide, 0.25% lanthanum nitrate, 6.25% platinum chloride, 1.25% cerium chloride and 2.25% silver nitrate were added into the complex solution to prepare nano photocatalytic materials with a particle size of 1-100nm Nano photocatalytic materials, sodium wanylbenzenesulfonate dispersing agent and deionized water were dispersed, mixed at 9:4:87, and dispersed by high shear dispersing machine 1 The fineness of slurry scraper was less than 10 μ M (2) nanometer 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: preparation of nano photocatalytic solution (1) during the preparation of active zinc oxide, 0.25% lanthanum nitrate, 6.25% platinum chloride, 1.25% cerium chloride, 2.25% silver nitrate (calculated according to the total amount of nano photocatalytic materials) are added to prepare the complex solution to make nano photocatalytic materials with a particle size of 1-100nm Nano photocatalytic materials, sodium wanylbenzenesulfonate dispersing agent and deionized water were dispersed, mixed at 9:4:87, and dispersed by high shear dispersing machine 1 The fineness of slurry scraper was less than 10 μ M (2) nano photocatalytic emulsion slurry preparation, nano photocatalytic slurry, pure acrylic modified emulsion, deionized water mixed with 40: 59: 1, dispersed by vacuum disperser, vacuum degree 0.09MPa, time 1H, temperature 20 - 28 C, nano photocatalytic emulsion slurry was prepared (3) Preparation of nano photocatalytic pigment and filler slurry Nanometer calcium carbonate, sericite (1250 mesh), talcum powder, iron dioxide, kaolin (800 mesh), nanometer photocatalytic liquid slurry, polyphosphate dispersant, white oil defoamer, glycol, dodecanol vinegar, hydroxyethyl cellulose, sn-632 thickener and deionized water are mixed according to 10:5:5:25:6:30:2.8:2.2:2:2:2:4, dispersed for 1H by high shear disperser, sanded for 1.5h, and the slurry scraper is fine When the degree is less than 30 μ m, nano photocatalytic pigment and filler slurry are prepared (4) coating preparation of nano photocatalytic emulsion slurry, nano photocatalyst, filling slurry, deionized water, mixed by 80:19:1, vacuum homogenizer dispersed 2h, filtration, packaging The product has good antibacterial 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,
