Coating knowledge: how to choose wall paint

Core tip: with the development of modern home furnishing market, consumers' pursuit in decoration is not only at the level of appearance, but also environmental protection is included in one of the most important considerations of home furnishings On this basis, the purchase requirements of decoration materials are increasingly strict, and the advantages and disadvantages of various environmental protection products on the market are mixed When the businessmen pull out the environmental protection brand, consumers How should we take action? Let's take a look at the wall paint Let's choose the material Three steps to understand VOC When buying wall paint, VOC is a topic that can never be separated from the promotion of the business, as if VOC is one of the wall paint Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of paint news: with the development of modern home market, consumers' pursuit in decoration is not only at the level of appearance, but also environmental protection is included in one of the most important considerations of home decoration On this basis, the decoration materials The purchase requirements are also increasingly strict, and the advantages and disadvantages of various environmental protection products are mixed in the market When the businessmen pull out the environmental protection brand, how should the consumers take the call? Let's take a look at the selection of wall paint Three steps to understand VOC when purchasing wall paint, VOC is a topic that can never be separated from business promotion, as if VOC is the absolute representative of harmful substances in wall paint, and also the health enemy of consumers, but what is VOC? What is the relationship between VOC and wall decoration? What is VOC? VOC full name is volatile organic Compounds is the general term of volatile organic compounds in the wall In building materials, they mainly include formaldehyde, ammonia, glycol, esters and other substances These substances are easy to volatilize due to their low boiling point In a short period of time, a large number of human contact will cause headaches, nausea, vomiting, fatigue and other phenomena Long term inhalation will damage the liver and kidney and nervous system, and even cause cancer risk Wall coating is one of the main sources of indoor VOC The content of VOC in the national standard shall not be higher than 200g per liter There are more strict restrictions on the content of VOC in different areas As one of the main indoor pollution components, VOC has become the first step for businesses to make articles on environmental protection products Is the lower the VOC content, the better? Consumers are afraid of the harm of VOC, so the merchants have played the banner of "zero VOC" on the products Think about it carefully If VOC is really useless in the coating, why has the VOC material kept in the coating production for a long time in the past? In fact, film-forming additives and antifreeze additives are the main sources of VOC in coatings Only by reducing the amount of these materials can the VOC be reduced, and the corresponding physical properties of coatings will be reduced Zero VOC is only a concept propaganda to a large extent There are few coating products that can reach the zero VOC standard on the market, but it is also the development of the whole industry Trend and direction of the exhibition How to avoid VOC injury? The most important thing to disperse VOC injury in home decoration is ventilation Do not rush to move in after decoration For qualified coating products within the scope of national standard, generally, VOC injury can be minimized through good ventilation and proper adsorption of activated carbon, etc., and proper selection of high-grade low VOC coating products can further help reduce VOC hidden danger There is a gap between the domestic and foreign definitions of clean taste technology in the purchase of modern home decoration building materials Sometimes there is a phenomenon of "talking about taste and color change" The special smell belonging to organic compounds seems to be a natural enemy in home decoration The emergence of clean taste technology also brings a brand-new indoor taste experience to consumers What is pure taste technology? In general, the traditional wall paint is to cover up the taste of the chemical substances in the building materials by adding spices in the later stage Although the content of some impurities is very low, the smell it emits will make the residents feel uncomfortable The clean smell technology is the goal of the coating product to reduce the smell in the coating tank and the smell after construction, while ensuring the original performance and environmental protection requirements of the product To minimize the content and odor of impurities Why is the price of pure flavor paint higher? On the one hand, the odor purification technology can require a lower VOC content, on the other hand, it can achieve the odor purification effect for the product There are two ways to achieve the effect: addition and subtraction Subtraction means to directly reduce the VOC and other impurities in the product, so that the taste will naturally reduce after it reaches a certain standard Addition means to add appropriate chemicals into the coating product, so as to mix with harmful ingredients Good neutralization can achieve the goal of purifying taste, but higher technical conditions are needed to realize this process, which also brings about the increase of cost Clean taste technology is equal to environmental protection paint? Clean taste technology originated in Japan, which originally refers to functional paint that can purify the odor and toxicity in the air, while in the domestic market, it mostly refers to wall paint with relatively small smell Although the pure flavor technology can reduce the impurity odor in the coating to the minimum, but the pure flavor technology is not equal to the coating product with zero VOC, and the general VOC content of the pure flavor coating itself is low, but there is no clear performance index for the pure flavor paint in the national standard, more is a product requirement and sales strategy of the brand itself, so when purchasing the pure flavor paint, choose Big brands are just as important Anti formaldehyde coating with different brand differences and effects is a new type of interior decoration material developed and promoted in recent years In addition to further reducing VOC content, the product itself can also play the role of decomposition and absorption of indoor formaldehyde, so as to achieve the effect of indoor purification What is anti formaldehyde technology? Anti formaldehyde technology mainly uses nano photocatalysis to degrade formaldehyde, and "microporous purification technology" of paint can absorb free formaldehyde molecules in the air With specific activity and nano photocatalyst, the paint coating will generate oxidation-reduction reaction under light, and release negative oxygen ions to degrade harmful substances, so as to achieve the effect of anti formaldehyde What is the anti formaldehyde effect of coating? In terms of function, the anti formaldehyde coating can play a good role in inhibiting the indoor formaldehyde content, but its effect is also questionable in detail Although the anti formaldehyde factor is added to the coating, its content is directly related to the anti formaldehyde ability In addition, the anti formaldehyde ability of the coating also has a certain buffer period, and the quality of various anti formaldehyde products on the market is not good or bad Qi, big brand products are often more trustworthy Formaldehyde resistance in the home starts from the product itself With formaldehyde resistant coating products, some consumers may have a certain degree of relaxation in the selection of materials In fact, the pollution in home decoration mainly comes from the purchase of building materials, while the products that rely too much on formaldehyde resistant technology can not bring too much guarantee for the health of interior decoration The health of home decoration still needs to start from the product itself to ensure that the pollution power of the product itself is minimized Bamboo charcoal paint with limited purification and adsorption capacity is becoming more and more common in the current decoration Just like activated carbon can absorb indoor harmful substances to purify the air, although bamboo charcoal exists in the paint, it can basically play the same role, mainly to achieve indoor harmful substances adsorption What is bamboo charcoal technology? Bamboo charcoal mainly refers to the air purification products made by carbonizing natural bamboo charcoal at a high temperature of more than 1000 degrees under anaerobic conditions Bamboo charcoal products have a lot of voids and large surface area, which can play an adsorption role on macromolecular substances in the air Is bamboo charcoal adsorption effective for a long time? Although bamboo charcoal adsorption factor is added to bamboo charcoal paint, the adsorption capacity of the paint depends on the number of bamboo charcoal factors on the one hand, and on the other hand, it also depends on its own adsorption capacity The adsorption capacity of bamboo charcoal materials has a certain upper limit, rather than long-term effectiveness On the contrary, when there are a large number of harmful substances in the room leading to wall adsorption saturation, it may be there After that, there was a problem of secondary pollution caused by slow release When businesses play environmental protection cards one after another, how should consumers take the call? The green technology of wall paint is constantly evolving, but no matter how the additional effect of the paint changes, the quality of its own products or the most important basis for consideration when purchasing, it is the greatest guarantee for health to see the product indicators clearly and choose products with low VOC when purchasing 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,
