Coating classification: film forming mechanism of coating

It is suggested that the film formation of the coating should go through two processes: 1 after construction, the moisture of the wet film gradually evaporated, and the dispersed particles gradually approached When approaching to a certain degree, the neighboring particles were tightly squeezed together, losing the freedom of movement and becoming gelatinous, and at this stage, the water could still be dispersed again 2 under the action of capillary force, the particles are in contact with each other, attract, flow and coalesce into the whole paint film, but at the glass transition temperature of the emulsion, though they are in contact with each other, they can not flow and coalesce together (so the construction temperature can not be too low) At high 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 Coatings home news: the film formation of coatings should undergo two processes: 1. After construction, the moisture of the coating wet gradually evaporated, and the dispersed particles gradually approached When approaching to a certain degree, the neighboring particles were tightly squeezed together, losing the freedom of movement and becoming gelatinous, and at this stage, the water could still be dispersed again 2 under the action of capillary force, the particles are in contact with each other, attract, flow and coalesce into the whole paint film, but at the glass transition temperature of the emulsion, though they are in contact with each other, they can not flow and coalesce together (so the construction temperature can not be too low) In the high temperature and dry weather or on the surface of the substrate with strong absorption, the water will volatilize faster or be absorbed by the substrate too quickly In these two cases, the wet film of the coating will not have enough film forming time and affect the film quality 3 as time goes on, the properties of the paint film change gradually, which is the result of the continuous coalescence and the interpenetration of polymer molecular segments after coalescence, which is why it takes days or more for the latex paint to dry 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,
