Coating process: production process of nano ecological exterior wall coating

Core tips: 1 Nano ecological exterior wall coating formulation: ingredient dosage / mass fraction content / mass fraction modified polyvinyl alcohol 35 whitening agent 0.02 nanometer Zinc Oxide 1.8 nanometer titanium dioxide 0.18 three oxidation two aluminum, 0.42 nickel oxide 0.15 talc powder 6 6, 0.03 heavy calcium carbonate 20 sodium bentonite 20 light calcium carbonate 8OK powder aluminum sulfate potassium alum silicon acrylate emulsion 2、 Process flow: 3、 Production process steps: ● mix the modified polyvinyl alcohol in the base material with an appropriate amount of 65-70 ℃ 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 Formula of nano ecological exterior wall coating: content / quality / quality modified polyvinyl alcohol 35 whitening agent 0.02 nano zinc oxide 1.8 nano titanium dioxide 0.18 aluminum oxide 0.42 nickel oxide 0.15 talcum powder 6 polyacrylamide 0.03 heavy calcium carbonate 20 sodium base bentonite 5.8 light calcium carbonate 8 OK powder 11 aluminum sulfate 0.03 Potassium alum 1.8 silicone acrylic emulsion 0.5 two, process flow: three, production process steps: - the modified polyvinyl alcohol in the base and the appropriate 65~70 degrees of water in the stirred tank to fully dissolve; then, nano Zinc Oxide, three oxidation two aluminum separately added, stirring evenly made of base material; ● add the prepared base material into the mixing tank at room temperature, add aluminum sulfate into 4 times of water for dissolution, then add the base material, then add nano titanium dioxide and nickel oxide for stirring, then add the thickener into 20 times of water, after dissolution, add the base material for full stirring; ● add the curing agent for full stirring, and finally add the heavy calcium carbonate, talcum powder and light calcium carbonate for stirring; ● grinding and dispersing in the grinder until the fineness is qualified is the finished product Nano zinc oxide and titanium dioxide need to be well dispersed and compatible before they are added into the formula 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,
