General knowledge of coatings: VOCs determination method of architectural coatings and adhesives at home and abroad

Core tip: the definition of VOCs is closely related to the test methods used, and different test conditions may lead to different results The most common consensus is that VOCs refer to organic compounds whose boiling point is equal to or lower than 250 ℃ Those substances with boiling points higher than 250 ℃ are not classified as VOCs and are often called plasticizers Relevant standards have been issued in China, such as GB18582-2008 limit of harmful substances in interior wall coatings for interior decoration materials, gb24408-2009 limit of harmful substances in exterior wall coatings for building and hj2 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 home news: the definition of VOCs is closely related to the test methods used Different test conditions may lead to different results The most common consensus is that VOCs refer to organic compounds whose boiling point is equal to or lower than 250 ℃ Those substances with boiling points higher than 250 ℃ are not classified as VOCs and are often called plasticizers This definition has been adopted in relevant standards issued in China, such as GB18582-2008 limit of harmful substances in interior wall coatings for interior decoration materials, gb24408-2009 limit of harmful substances in exterior wall coatings for building and hj2537-2014 technical requirements for environmental sign products water-based coatings The definitions of VOCs in different standards are shown in the table 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,
