    Core tips: 1 Alkali resistant opaque primer Formula: raw material formula /kg dispersant 2 wetting agent 1.5 propylene glycol 10 preservative 1.5 defoaming agent 3 titanium white 48 heavy calcium carbonate 47 talcum powder 20 anti alkali emulsion 550 alcohol ester twelve 25 thickening agent viscosity thickening agent ammonia water right amount to water anti alkali sealing opaque primer, the product has super penetrability and sealing, good adhesion to wall, anti penetration, and has a certain hiding power, can be reduced Use less topcoat 2 Production process: ① Powder beating: A ready 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 Coatings home news: 1, alkali resistant opaque primer formulation: raw material formulation /kg dispersant 2 wetting agent 1.5 propylene glycol 10 antiseptic 1.5 defoaming agent 3 titanium white 48 48 heavy calcium carbonate 47 talcum powder 20 alkali resistant emulsion 550 alcohol ester twelve twelve thickening agent viscosity thickening agent ammonia water amount to water Anti alkali sealing opaque primer, the product has super permeability, sealing; good adhesion to the wall, anti permeability; with a certain covering power, can reduce the use of the top coat 2 Production process: ① beating the powder: A prepare the mixing and dispersing machine, start the mixer (adjust the rotating speed to about 200R / min), add the dispersant, wetting agent, propylene glycol, preservative, defoamer and 210kg water in a clean cylinder in turn, after adding, speed up the mixer to 400-500r / min, keep it for about 20min, until the dispersant is evenly distributed b Slowly add titanium dioxide powder, heavy calcium carbonate and talcum powder in turn After adding, speed up the mixer to 1000-1200 R / min, and continue to mix and disperse for 30min c Take samples and check the fineness If it is qualified, the grouting process is basically completed Otherwise, high-speed dispersing and stirring, or discharging to the grinder, grinding until the fineness is qualified ② Paint mixing: A dilute the thickener evenly with 15kg water, and reserve b Use 40kg water to dissolve the thickener evenly (it can be dissolved 1-2 days in advance) for standby c Start the mixing and dispersing machine for paint mixing (the rotating speed is adjusted to about 200R / min), and add the powder slurry with qualified fineness into the clean cylinder Then alkali resistant emulsion, film builder and residual defoamer were added After mixing, the blender was increased to 300r/min for a long time d Adjust the pH value to 9.0 with ammonia water, and then add the water solution of viscosity thickener E washed the empty bottles of the used emulsion with the remaining water, and washed the water back to the cylinder, then added the thickener diluent slowly, adjusting the viscosity of the system to 95 to 102KU f For discharging, bag filter is selected to filter, weigh and barrel the finished product 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,
