    Key tips: acrylic latex paint formula: Ingredients: /kg pure acrylic emulsion 273 hydroxyethyl cellulose 3.4 propylene glycol 6.7 ethylene glycol 1510% sodium tripolyphosphate water 10.4 10.4 sodium hypophosphite 1.3 emulsifying wetting agent 0.4 defoamer 1.6DH-LEX disinfectant 0.4 titanium white rutile 127 calcium carbonate (400 mesh) talcum powder (400 mesh) Zinc Oxide (dipper) water added to Production process: (1) weigh the pure acrylic emulsion according to the formula (2) Hydroxyethyl fiber Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: acrylic latex paint formula: ingredients /kg pure acrylic emulsion 273 hydroxyethyl cellulose 3.4 propylene glycol 6.7 ethylene glycol 1510% sodium tripolyphosphate solution 10.4 six sodium hypophosphite 1.3 emulsifying wetting agent 0.4 defoamer 1.6 DH-LEX bactericide 0.4 titanium white powder (Jin Hongshi type) 127 calcium carbonate (127 mesh) talcum powder (Zinc Oxide) Add water to 1000 production process: (1) weigh the pure acrylic emulsion according to the formula (2) 3.4 kg of hydroxyethyl cellulose, 132.6 kg of water were added and dissolved to 136kg of aqueous solution (concentration 2.5%) (3) Take 48.5kg of water and add it to the mixing bucket, add 80kg of hydroxyethyl cellulose aqueous solution, start the mixer (speed 300r / min), add glycol, titanium dioxide, calcium carbonate, zinc oxide and talcum powder, and then mix for 20min at high speed (speed 1000r / min) to make it a soft thick slurry If it is too thick to be stirred and dispersed, the aqueous solution of cellulose can be added as appropriate, as long as it can be stirred and dispersed after dilution (4) reduce the speed of the mixer to 300r/min, so that the emulsion can be added (5) pretreatment of acrylic emulsion: add the emulsion in the formula to the barrel, add propylene glycol, stir evenly, add emulsifying wetting agent, and stir well (6) add the processed emulsion to the stirring step (4), stir for several minutes, add the remaining cellulose solution and add the remaining 20min after slowly adding the remaining dilute The finished product is obtained by using 160 mesh fine mesh screen, holding large brush manually and forced filtration It is packed in plastic barrels with the lid tightly closed 1000 kg latex coating is obtained Note: (1) this product is white emulsion paint for flat wall (2) If you want to make a colored paint, you can add the color of the paint you want If the color material of iron oxide system is used, the color paste which has been emulsified and ground to less than 20 μ M can be used in advance If the color is required to be deep, the amount of heavy calcium, namely talcum powder, should be reduced appropriately to ensure that the solid content of the coating is kept at about 42%, otherwise the coating is too thick to affect the leveling (3) The system degree of coating is high, leveling, easy to apply, covering power is good, and the time of no powder removal is long (4) The pH value of this product is about 9.5, otherwise the dosage of sodium triphosphate should be adjusted 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,
