Anti-static floor veneer cracking causes
Analytical anti-static floor cracking There are many reasons, such as: the use of adhesives in the production process of the floor substrate, and formaldehyde is one of the main components of the adhesive, so the floor often contains formaldehyde, formaldehyde is called "invisible killer." According to the national standards, the amount of formaldehyde released from the substrate must meet the E1 standard, that is, the formaldehyde emission should be less than 9mg/100g. Substrates lower than this standard are harmless to the human body. When buying a wood floor, if you smell a pungent odor, don't buy it. A good floor should be damp-proof. The moisture-proof performance is reflected by the index of water-absorption thickness expansion. The higher the index value, the worse the moisture-proof performance. On the other hand, floors with poor moisture resistance are likely to have problems such as expansion and deformation in the wet conditions of the spring rainy season. If the environmental humidity of the anti-static floor is not up to the national standard, any equipment in the equipment room will have serious consequences if it does not reach the level of anti-static electricity. The main reason is that there is no humidity and no static electricity can be conducted. Static electricity can not release static electricity, causing static electricity everywhere in the equipment room, resulting in equipment failure or even paralysis. The temperature and humidity of the equipment room in the northern regions are generally unable to meet the national standards, especially in winter when the heating environment is turned on. Such an ambient temperature and moderate temperature can easily cause accelerated shrinkage of melamine veneers, resulting in veneer shelling and cracking.
