Common knowledge of coating: the way to realize low VOC polyurethane coating and its application

Core tip: VOC (volatile organic compounds) refers to the volatile solvent in solvent based coatings which can cause diseases after contact with human body or inhalation VOC is often contained in polyurethane coating VOC is harmful to human health It not only erodes the skin, but also stimulates and destroys the central nervous system, hematopoietic organs and respiratory system It can cause headache, nausea, chest distress, fatigue, vomiting and other symptoms In serious cases, it can convulse, coma or even die Every year around the world due to the use of toxic chemical solvent based coatings 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 Coating House News: VOC (volatile organic compounds) refers to the volatile solvent in solvent based coatings that can cause disease after contact with human body or inhalation VOC is often contained in polyurethane coating VOC is harmful to human health It not only erodes the skin, but also stimulates and destroys the central nervous system, hematopoietic organs and respiratory system It can cause headache, nausea, chest distress, fatigue, vomiting and other symptoms In serious cases, it can convulse, coma or even die The global economic loss caused by environmental damage and human injury caused by the use of toxic chemical solvent based coatings is up to tens of billions of dollars every year Therefore, the world's major coating manufacturers have introduced regulations to limit VOC emissions For example, in the international community, according to the European Community Ecological standard products - the VOC limit, the most commonly used class of coatings for home decoration is 30 g / L the national compulsory standard of coatings in China, the limit of harmful substances in interior wall coatings for interior decoration materials, stipulates that VOC shall not exceed 200 g / L Therefore, the development of low VOC polyurethane coating is the development direction of polyurethane coating 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,
