Coating process: production process of interior wall emulsion paint (taking 1t as an example)

Core tips: 1 Add 200kg water into the dispersion tank, rotate at low speed, and the rotating speed is 100-200r / min; 2 Add 15 kg of glycol, 2 kg of wetting agent, 15 kg of dispersant, 1 kg of bactericide, 1.5 kg of defoamer and 1 kg of leveling agent in turn, and disperse at high speed (900-1200r / min) for 5 minutes after adding; 3 In the medium speed state, the rotating speed is 500-600r / min, and then add 100 kg of lithopone, 50kg of anatase titanium dioxide, 200kg of light calcium, 100kg of heavy calcium, 100kg of talc, and 100kg of hydroxyethyl 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 Paint Home News: 1 Add 200kg of water into the dispersion tank, rotate at a low speed, with a rotating speed of 100-200r / min; 2 Successively add 15kg of glycol, 2kg of wetting agent, 15kg of dispersant, 1kg of bactericide, 1kg of defoamer, 1kg of leveling agent, and disperse for 5 minutes at a high speed (900-1200r / min); 3 In the medium speed state, the rotating speed is 500-600r / min, then add 100kg lithopone, 50kg anatase titanium dioxide, 200kg light calcium, 100kg heavy calcium, 100kg talcum powder and 2kg hydroxyethyl cellulose in turn, and disperse at high speed for 30 minutes; 4 After the dispersion is uniform, conduct 1-2 times of sanding to make the fineness reach 40-50 μ m (detected by scraper fineness meter); The above steps are dispersing teeth The following steps are to stir the teeth 5, and after the fineness meets the requirements, in the low speed stirring state, a film forming agent 8kg is added successively, stirring for a few minutes, then adding styrene acrylic emulsion 150, defoamer 1.5kg, and multi-functional auxiliaries about 1.2kg, so that the pH value reaches 9-10 (detected by pH test paper); 6, Dilute the alkali swelling thickener with 3 times of water, i.e add about 6 kg of thickener into 18 kg of water, stir evenly, and then slowly add it into the slurry In the same way, dilute about 3 kg of associated thickener with 9 kg of water, stir evenly, and then slowly add it into the slurry, so that the viscosity of the slurry can reach 100-110k μ (measured by stomer); 7 Test the pH value of the slurry again to make it reach 8-9; 8 Filter the slurry that meets the requirements with 120 mesh gauze; 9 Can, measure and store 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,
