Coating process: production process of exterior wall coating

Core tips: 1 Add water into the mixer, add glass beads, ultra-fine calcium bicarbonate, barium sulfate, calcined kaolin and talcum powder, mix evenly, pump people to disperse the grinding tank, disperse the grinding, and clean the mixing tank with residual water The dispersing grinding time is 2 hours 2 Water soluble acrylic resin (PA) and diacetone acrylamide were mixed and stirred, copolymerized and grafted, and then copolymerized and crosslinked at room temperature for 1 hour Water soluble polyurethane resin (PU), adipic acid two hydrazide and ammonia water were mixed well, and the emulsion was microscopical and alkaline At acid room temperature, Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: 1 Add water into the mixer, add glass beads, ultra-fine calcium bicarbonate, barium sulfate, calcined kaolin and talcum powder, mix evenly, pump people to disperse the grinding tank, disperse the grinding, and clean the mixing tank with residual water The dispersing grinding time is 2 hours 2 Water soluble acrylic resin (PA) and diacetone acrylamide were mixed and stirred, copolymerized and grafted, and then copolymerized and crosslinked at room temperature for 1 hour Water soluble polyurethane resin (PU), adipic acid two hydrazide and ammonia water were mixed well, and the emulsion was microscopical and alkaline At acidic ambient temperature, ketone carbonyl and hydrazine groups will dehydrate to form hydrazone compounds, thus achieving room temperature crosslinking of the emulsion The reaction mode of ketone carbonyl group and hydrazine group is =C=O+HN2NH2 =C=N-NH- ten H2O, which improves the stability of the 2 resin blend, and the self crosslinking is formed when drying Then nano silica colloidal solution is added to make the resin riveted on the surface of silica, and the lipophilic group is outward, so as to improve the water resistance of the coating 3 Pump the milled material into the crosslinked and riveted resin nano emulsion, mix it, add styrene acrylic emulsion, defoamer, smoother, and mix it fully OK paint home is focused on the news and coating of coating, diatom mud, paint coating, coating process, fire-resistant coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fire-resistant coating,
