Paint technology: how to configure special color paint

Core tip: first of all, the director and engineer of the paint factory (including the painter) think that it is difficult to preserve the color of dark latex paint When the consumer requests to process a lighter latex paint, the quality does not change when the finished paint is adjusted to light color, but when the customer purchases dark color (when the amount of color paste is more than 2%), they still take the original shift of the finished paint or white latex paint formula To produce without moving is to add color paste continuously, and to finish when the phase color meets the customer's requirements The latex paint produced in this way will fade in a few months if it is sunny three days before and after construction Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of paint news: first of all, the director and Engineer (including painters) of the paint factory think that dark latex paint It's difficult to maintain color When consumers require to process a lighter color latex paint, the quality will not change from the finished paint to the light color, but when customers buy a dark color (when the amount of color paste is more than 2%), they still take the formula of the finished paint or white latex paint to produce in the original shift, that is, they constantly add color paste, and think that the phase color will be finished after meeting the customer's requirements Work The latex paint produced in this way will fade within a few months if it is sunny before and after construction If it rains within two days after construction, it will fade immediately Reason 1: the color paste is the pigment The more the color paste is added, the pigment of this emulsion paint is obviously increasing, that is, the color base ratio is not the ratio of white paint Reason 2: the darker the color, the lower the viscosity of the emulsion paint That is to say, the viscosity of the emulsion paint is also significantly reduced while the color paste is constantly added It can be seen by the naked eye that this emulsion paint is not a reasonable formula for white paint In order to achieve certain quality, emulsion, film builder and thickener must be added So that its quality can meet the requirements of customers and ensure the adhesion and water resistance of latex paint unchanged Secondly, most of the titanium dioxide used in the production of emulsion paint is mainly produced by sulfuric acid method Due to the technological relationship, the color phase is inconsistent When receiving the joint pass project, Party A requires that the color of the whole community should be the same When the first batch of coating is produced, after color correction, a little black paste should be added to make it a little darker than the original sample, so as to prevent the titanium dioxide and filler purchased in the future from being yellow or gray, so as to leave room for rotation for the factory 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,
