    Core tip: there are three misunderstandings in the purchase of paint: paint can also be drunk? From 0voc to the current low-carbon environmental protection, from scrub resistance to covering cracks, the publicity about high environmental protection and high performance of paint is endless Some experts say that consumers are more or less affected by these propaganda when purchasing, and even enter the misunderstanding of "the more environmental protection is, the better" and "the more functions are, the better" Here are three misunderstandings Let's take a look at them together One is that zero VOC is the best building material commodity, and the environmental protection of coatings has become the business and consumer Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: Three Misunderstandings in the purchase of paint: paint can also be drunk? From 0voc to the current low-carbon environmental protection, from scrub resistance to covering cracks, there are endless publicity about high environmental protection and high performance of paint Some experts say that consumers are more or less affected by these propaganda when purchasing, and even enter the misunderstanding of "the more environmental protection is, the better" and "the more functions are, the better" Here are three misunderstandings Let's take a look at them together One is that zero VOC is the best building material product, and the environmental protection of coatings has become the focus of businesses and consumers VOC of coating refers to the total amount of organic compounds contained in the coating, which are the main components of the main film-forming substances of the coating The main function of the film-forming material is to enhance the viscosity of the coating, that is to say, it plays the role of wall hanging If the VOC content is reduced, it is likely to lead to a corresponding decrease in the viscosity of the coating, resulting in paint powder, blistering, cracking, low scrub resistance If the quality of the coating is not considered, it is simple to reduce the VOC content For example, adding more water to the coating can reduce the VOC content Therefore, some small coating manufacturers can make VOC very low, but the quality can not be guaranteed As a product directly entering the family, coating has a compulsory national standard, and the qualified products sold on the market have reached this standard, which are environmentally friendly and harmless to human body Therefore, consumers do not need to focus on the "environmental protection" and VOC content when purchasing coatings, as long as they are qualified products in line with national standards, they can be assured of purchasing Error 2: the pursuit of self-cleaning function and the number of scrubbing resistance At present, many coating companies take the self-cleaning function of products and the number of thousands of scrubbing resistance as the propaganda point Self cleaning is applied to the exterior wall coating, which refers to the stain resistance of the coating, that is, the dirt resistance as the saying goes Specifically speaking, the coating is not easy to touch the lime soil after treatment, and the lime soil on the surface can be washed off by the washing of rainwater, so as to achieve the cleaning effect Although some businesses inject self-cleaning function into the interior wall coating, in fact, most of the interior wall cleaning is still done by manual scrubbing According to the national standard, the number of scrubbing resistance of qualified coatings shall not be less than 300, while the number of scrubbing resistance publicized by some coatings has reached tens of thousands, which is a good thing, indicating that the scrubbing resistance of these coatings is good, but the cost shall be increased accordingly As a consumer, I wipe the wall once a day, only 3560 times in ten years Therefore, consumers should not excessively pursue self-cleaning function and scrub resistant times when purchasing interior wall coating Myth 3: can cover cracks is anti crack coating many consumers think can cover cracks is anti crack coating In fact, the function of crack prevention and coating covering micro cracks is different It's not that the wall cracks, and the coating won't crack There are indeed elastic coatings with thick film on the market, but this kind of coating is mostly used for external walls, which are basically difficult to use in indoor walls, and the cost is very high There is no specific requirement for the elasticity of coating in the national standard In some coastal areas, because the foundation sinks every year, the wall surface is easy to crack, so this kind of elastic coating is widely used However, as an ordinary consumer, it is not necessary to use high-cost elastic coating in home decoration Experts suggest that when consumers purchase coatings, they may as well look at the coating test report and make a comprehensive analysis of other aspects of the coating For example, alkali resistance of paint: the alkali resistance of paint If the alkali resistance of paint is not strong, it is easy to turn yellow after a period of time After making a comprehensive analysis, choose the products you really need 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,
