Common sense of coating: misunderstanding of coating toxicity

Core tip: when people decorate houses, they have misunderstandings about the toxicity of building materials, especially the toxicity of coatings, which are mainly manifested in: First, it is unscientific to think that the toxicity of paint will evaporate in a short period of time, as long as there is no harm in a few weeks Under normal temperature, the volatilization and dissipation of these toxic substances is a long process, and long-term low-dose exposure to toxic substances will produce serious non acute (because it is not acute, it is often not detected) harm, which has been confirmed by a large number of toxicology research results Second, it is considered that the amount of VOCs in coatings can represent the toxicity 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 Paint Home News: when people decorate houses, they have misunderstandings about the toxicity of building materials, especially the toxicity of paint The main manifestations are as follows: first, it is unscientific to think that the toxicity of paint volatilizes in a short period of time, as long as there is no harm in a few weeks Under normal temperature, the volatilization and dissipation of these toxic substances is a long process, and long-term low-dose exposure to toxic substances will produce serious non acute (because it is not acute, it is often not detected) harm, which has been confirmed by a large number of toxicology research results Second, it is unscientific to think that the amount of VOCs in coatings can represent the toxicity VOCs are only a source of toxicity of coatings, and not all VOCs have high toxicity Some VOCs are not very toxic, which is the basis of developing new generation of low toxicity products As a kind of chemical index, VOC is not equal to toxicity Third, the toxicity of coatings can only be expressed by biological detection, and physical and chemical tests can not express the toxicity completely Fourth, the toxicity control of coatings refers to the process of dynamic development with technological progress in terms of comparison among similar products Therefore, it can not be compared with the non-toxic distilled water A good coating product should be scientifically expressed as low toxic, not non-toxic 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,
