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

Core tips: 1 Add 150 kg water into the dispersion tank, rotate at a low speed and rotate at a speed of 100-200r / min; 2 Add 15 kg of glycol, 1 kg of wetting agent, 10 kg of dispersant, 1.5 kg of defoamer, 1 kg of bactericide and 1 kg of leveling agent in turn After adding, disperse at high speed (900-1200r / min) for 5 minutes; 3 In the medium speed state, the rotating speed is 500-600r / min, 150 kg of rutile titanium dioxide, 50 kg of calcined kaolin, 100 kg of wollastonite, 100 kg of heavy calcium are added in turn, sliding Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: 1 Add 150 kg of water into the dispersion tank, rotate at a low speed, with a rotating speed of 100-200r / min; 2 Successively add 15 kg of glycol, 1 kg of wetting agent, 10 kg of dispersant, 1.5 kg of defoamer, 1 kg of bactericide and 1 kg of leveling agent; after adding, disperse at a high speed (900-1200r / min) for 5 minutes; 3 In the medium speed state, the rotating speed is 500-600r / min, 150 kg of rutile titanium dioxide, 50 kg of calcined kaolin, 100 kg of wollastonite, 100 kg of heavy calcium, 50 kg of talcum powder and 2 kg of hydroxyethyl cellulose are added in turn, and then dispersed at high speed for 30 minutes; 4 After the dispersion is uniform, conduct 1-2 times of sanding to make the fineness reach 50-60 μ m (detected by scraper fineness meter); 5 When the fineness meets the requirements, the film forming AIDS 12kg, styrene acrylic emulsion 300kg, defoamer 1.5kg, and multi-functional auxiliaries about 1.2kg at low speed stirring state are added, so that the pH value of the slurry is 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 4 kg of associated thickener with 12 kg of water, stir evenly, and then slowly add it into the slurry, so that the viscosity of the slurry can reach 90-100k μ (measured by stomer); 7 Check the pH value of the slurry again to make it reach 8-9; 8 Filter the slurry meeting the requirements with 120 mesh emery cloth; 9 Can, measure and store it in the warehouse 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,
