    Core tip: basic formula: See the following table for the basic formula of paste phase change thermal insulation putty Raw material mass fraction /% elastic acrylic emulsion 25-35 VAE7078-15 six sodium hypophosphite 0.2-0.5 defoamer 0.3-0.5 mould inhibitor 0.2-0.3 ethylene glycol 1.0-1.5 wood fiber 2.0-3.0 hydroxypropyl methyl cellulose 0.1-0.2 sepiolite stabilized phase change material 15-25 heavy calcium powder (400-600 mesh) 5-10 talcum powder (400-600 mesh) 5-10 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: basic formula: the basic formula of paste phase change energy storage insulation putty is shown in the table below Raw material mass fraction /% elastic acrylic emulsion 25-35 VAE707 8-15 sodium six phosphate sodium defoamer 0.3-0.5 fungicide 0.2-0.3 ethylene glycol 1.0-1.5 wood fiber 2.0-3.0 hydroxypropyl methyl cellulose 0.1-0.2 sepiolite stabilized phase change material 15-25 heavy calcium powder (400-600 mesh) 5-10 talcum powder (400-600 mesh) 5-10 ceramic hollow beads (500 mesh) 10-20 water allowance, 0.3-0.5 Preparation process: ① for the preparation of sepiolite shaped phase change material, add an appropriate amount of 10% NaOH solution into the reactor, add an appropriate amount of stearic acid under agitation, heat until stearic acid melts, add 20% water, heat to boiling, add paraffin to complete dissolution, add residual boiling water, and stir evenly Slowly add the dried sepiolite powder, heat preservation and stirring at 80 ℃ for 1 h, and wait for use after cooling Secondly, the emulsion, dispersant, defoamer, mould inhibitor, glycol and hydroxypropyl methyl cellulose aqueous solution and wood fiber were evenly dispersed, then sepiolite stabilized phase change material, heavy calcium, talcum powder and ceramic hollow microspheres were added to form a uniform paste 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,
