Common knowledge of coating: why do indoor air quality standards and specifications require volatile organic compounds, free formaldehyde and heavy metal content?

It is suggested that a certain amount of organic compounds, mainly including aromatic hydrocarbon, straight chain hydrocarbon, aldehyde, alcohol, ester and so on, will be emitted during the construction of architectural coatings Even after the coating surface is dry, a small amount of residues will be released slowly, but the concentration is much lower than the former These organic compounds are one of the main sources of indoor VOC, which are harmful to human health The toxicity of different organic substances is different, which will damage the nervous system, blood system, kidney and liver of human body 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 coatings news: in the construction process, building coatings will emit a certain amount of organic compounds, mainly including aromatic hydrocarbons, straight chain hydrocarbons, aldehydes, alcohols, esters, etc., even after the coating surface is dry, there are still a small amount of residual slow release, but the concentration is much lower than the former These organic compounds are one of the main sources of indoor VOC, which are harmful to human health The toxicity of different organics is different, which will damage the nervous system, blood system, kidney and liver of human body; some benzene series are carcinogens, so the impact on indoor air and harm to human body should be minimized Free formaldehyde is very irritating to eyes, respiratory tract and skin, which can cause allergic reaction in some people The international cancer center lists it as a suspected carcinogen in humans In solvent based coatings and various latex coatings, the raw materials do not contain formaldehyde, but some additives used, such as formaldehyde releasing bactericide, will contain a very small amount of formaldehyde Due to the formaldehyde contained in the raw materials, if the reaction is not complete, the coating will inevitably contain free formaldehyde, which will cause harm to human body Therefore, the impact on indoor air and the harm to human body should be minimized 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,
