    Core tip: water based coating is a kind of coating with water as solvent As a substitute of solvent based coating system, it has been gradually recognized by people In recent years, because the ideal water-based coating has no pollution to the human ecological environment and has certain advantages in transportation and use performance, its products are quickly accepted by the market, and called high-tech replacement products Here is the introduction The production process of waterborne coatings is described as follows: (1) basic production process of Waterborne Coatings The production process of water-based paint is the process of putting raw materials of various components into a certain order and dispersing evenly The production process of general latex paint includes Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Home of coatings: Water based coating is a kind of coating with water as solvent As a substitute of solvent based coating system, it has been gradually recognized by people In recent years, because the ideal water-based coating has no pollution to the human ecological environment and has certain advantages in transportation and use performance, its products are quickly accepted by the market, and called as high-tech replacement products Next, we will talk about water-based coating system Production process of water-based paint: (1) the basic production process of water-based paint the production process of water-based paint is the process of putting raw materials of various components into a certain order and dispersing evenly The production process of general latex paint includes three parts: ① Preparation of slurry: firstly, put liquid materials such as water, dispersant, defoamer and preservative into the dispersion tank, mix them evenly, put coloring pigments and physical pigments in turn under the stirring state, and accelerate the dispersion for 20-40 minutes; ② Preparation of waterborne coatings: put the emulsion into the paint tank, add thickening agent, pH regulator, antifreeze agent, film builder, defoamer and other auxiliaries, stirring for about 15 minutes, until completely uniform, then detect the material ③ Coating filtration and product packaging: in the production process of latex paint, because a small part of pigment (filler) has not been dispersed, or because of breaking emulsification into particles, or there are impurities in the coating, the coating at this time needs to be filtered to remove the coarse particles and impurities in order to obtain a good quality product According to the different requirements of the product, different specifications of screen and different containers can be selected for packaging, And do well in measurement, so as to get the final product (2) Key points in the preparation of waterborne coatings: ① pigments and ultra-fine fillers with good dispersibility shall be selected as far as possible, so as to cancel grinding operation, simplify production process and improve production efficiency on the premise of stable improvement of product quality; ② In the early stage of dispersion, a proper amount of HEC can be put in advance, which is not only helpful for dispersion, but also can prevent or reduce the phenomenon of slurry sticking to the wall and improve the dispersion effect; ③ Before adding liquid thickeners, it is necessary to use 3~5 times water to dilute, then add slowly when fully stirred, and prevent the local thickeners from being too high The thickener can be placed in the slurry after mixing the slurry into the slurry to avoid the above problems Half of the defoamer is added to the slurry, and the other half is added to the paint preparation process, so that the defoaming effect is better; in the paint mixing process, the mixing speed should be controlled at 200 ~ 400R / min to prevent the introduction of a large number of bubbles in the production process, which will affect the quality of the paint 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,
