Paint knowledge | latex paint knowledge

Core tip: it is understood that whether it is paint, primer, colorant or sealer, there are usually four components, namely binder, liquid, pigment and additive Recently, the consumer guidance committee of China Consumer Association and Rohm Haas latex paint quality Institute jointly launched the consumer guidance series manual of China Consumer Association - what is in a barrel of paint? 》As a knowledge popularization manual to help consumers understand latex paint, it will gradually be distributed to consumers free of charge in large paint markets in Beijing, Shanghai, Guangzhou, Chengdu and other cities The contents of the manual will also be published on the website of China Consumer Association for consumers to consult Several ways of roller coating Recommended introduction: roller coating includes rubber roller coating, insert plate roller coating and ceramic rubber roller coating The following is a detailed introduction of these three ways of coating The function of roller rubber coating is to increase the friction derivative between the conveyor belt and the cylinder surface during transmission, so as to reduce the friction coefficient of the conveyor belt on the cylinder surface, reduce the mutual wear of the sliding machine of the conveyor belt on the cylinder surface, improve the traction force during operation, and extend the service life of the conveyor belt and the electric roller One, three, six, 8385-7180 (V) rubber rollers are covered with diamond rollers and flat rollers, generally pure rubber plates The rubber coating of the inserted plate roller is divided into tile shell type roller and Paint Home News: it is understood that whether it is paint, primer, colorant or sealer, there are usually four components, namely binder, liquid, pigment and additive Recently, the consumer guidance committee of China Consumer Association and Rohm Haas latex paint quality Institute jointly launched the consumer guidance series manual of China Consumer Association - what is in a barrel of paint? 》As a knowledge popularization manual to help consumers understand latex paint, it will gradually be distributed to consumers free of charge in large paint markets in Beijing, Shanghai, Guangzhou, Chengdu and other cities The contents of the manual will also be published on the website of China Consumer Association for consumers to consult The two agencies will also continue to launch guidance manuals to guide consumers in the correct selection and use of latex paint, which will also be provided to consumer associations across the country for consumption and consumer demand "61% of consumers buy latex paint to decorate their new houses, 32% of them paint their old and aged walls; only 5% of consumers want to change the color of their rooms." This is the result of a special survey of latex paint consumption by Rohm Haas latex paint quality Institute (China), a non-profit organization, recently released by China Consumer Association, among more than 1000 consumers aged 25-50 in four major cities of Beijing, Guangzhou, Shanghai and Chengdu These consumers have painted their homes in the past year, or within the next six months It is reported that most consumers do not know the basic ingredients of latex paint, and can not actively judge the quality of a barrel of latex paint and whether it is suitable for the painted wall Although consumers pay most attention to "raw material quality", "latex paint quality" and "brand awareness" when purchasing latex paint, most consumers believe that the quality difference between famous brands is not big, and 63% of consumers are willing to buy latex paint with poor quality in order to save costs According to the survey, consumers have not paid attention to several important professional indicators that affect the construction quality and application effect of latex paint, such as leveling, not easy to splash and anti adhesion, etc., and they have little knowledge of latex paint, and they do not pay attention to the construction quality of latex paint In general, the house is repainted every 5-7 years Experts predict that with the development of Chinese market, especially in Shanghai and other big cities, the proportion of old houses to be repainted will gradually expand In addition, the continuous improvement of the economic level will also change the current phenomenon that most people only use latex paint as a decoration material In Europe and America, latex paint has become a fashion element and an important form of color expression, second only to clothing Key words about coatings ■ glossiness in the market, consumers can mainly see flat (matte), satin (mercerize) and high gloss types In fact, the glossiness of the coating is formed by the pigments and binders contained in the coating Generally speaking, the more binder content, the better glossiness of coating Therefore, compared with matte coating, the cost of high gloss coating will also be increased, and the price will be correspondingly more expensive And the film formed by high gloss coating is very smooth and dense Therefore, it is not easy to accumulate dust and stains, and moisture is not easy to penetrate Therefore, it is not easy to stain, clean and mould So high gloss paint is more suitable for kitchens and bathrooms ■ do not over dilute the coating when painting In addition to special circumstances such as spraying, the operation shall be carried out according to the manufacturer's instructions Over dilution will reduce the solid content per unit volume of the paint and make the paint film too thin, thus weakening the anti cracking, covering power, fluidity and leveling, gloss consistency and other properties of the paint In addition, dilution will cause the coating to hang on the vertical surface, and the film formed after drying at the place of hanging is very thin, which is the performance of the coating is damaged In a way, it also increases the cost of repair ■ although the development of low-end latex paint industry is very fast, there are still many problems According to the survey of relevant departments, China currently has more than 8000 construction coating manufacturers, but most of them are small and medium-sized enterprises These enterprises mainly sell low-end products in the market, and the performance of low-end products in the market has caused the prejudice that most of the consumers think that the quality of construction coating is poor ■ the quality of the paint is not correctly used by the decoration workers or there is a wrong judgment on the environment and temperature during the construction process, resulting in poor quality of the wall painting, which may make consumers think that the quality of the paint itself has problems ■ whether the safety index latex paint will cause harm to the body, i.e whether the health index, environmental protection and safety of the product are the most concerned indexes for Chinese consumers at present 99% of Beijing consumers think that the health, environmental protection and safety of the product are the most important indexes, which indicates that the consumers in Chinese cities have generally been aware of environmental protection Several other indicators that consumers are most concerned about include whether the product is resistant to cleaning, scrubbing, contamination, cracking, peeling and discoloration ■ at present, consumers have not paid attention to several important professional indicators that affect the construction quality and painting effect of latex paint, such as leveling, splash resistance and adhesion resistance, which shows that consumers have not much knowledge of latex paint and do not know how to pay attention to the construction quality of latex paint Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating,
