Coating process: production process of emulsion paint

Core tip: latex paint is a kind of commonly used architectural coating product, which is made up of emulsion, pigment, filler, additives and water Emulsion is the most important raw material for the performance of latex paint, usually synthetic resin emulsion Compared with other coatings, the production process of latex paint is relatively complicated 1 Discharge water; 2 Put in microbicide; 3 Put in film-forming assistant; 4 Adding thickener; 5 Put pigment dispersant; 6 Launch cancellation 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 Coatings home: latex paint is a kind of commonly used architectural coating product, which is made up of emulsion, pigment, filler, additives and water Emulsion is the most important raw material for the performance of latex paints, usually is synthetic resin emulsion; compared with other coatings, the production process of latex paint is relatively complex, latex paint production process mainly has the following major steps: 1, throwing water; 2, put in killing microbiological agent; 3, put film forming AIDS; 4, put thickeners; 5, put pigment dispersant; 6, put in defoamer and wetting agent; 7, release pigments and fillers; 8, put in lotion; 9, pH adjuster; 10, put in other auxiliaries; 11, put water and / or thickener solution Operation procedures for latex paint production process: put water into high-speed mixer first, and then add microbicide, film-forming agent, thickener, pigment dispersant, defoamer and wetting agent at low speed After the mixture is even, the pigment and filler are slowly screened into the vortex stirred by the impeller Soon after adding pigments and fillers, the abrasives become thicker At this time, the distance between the impeller and the bottom of the mixing barrel shall be adjusted to make the vortex into a shallow basin After adding the finishing filler, the impeller speed shall be increased (the linear speed along the wheel is about 1640m / min) In order to prevent excessive temperature rise, it is necessary to stop for cooling, and scrape off the color and filler adhering to the barrel edge when stopping Measure the fineness of the blade at any time When the fineness is qualified, the dispersion is completed After dispersing, slowly add emulsion and pH adjustment agent at low speed, then add other auxiliaries, then adjust the viscosity with water and / or thickener solution, screen out the material 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,
