Non-environmental blockboard directly causes pollution in the living room. Even if the environmentally friendly product is used too much, it is easy to cause cumulative pollution. The "10 mandatory national standards for hazardous materials for interior decoration materials" stipulates that the release of formaldehyde from large core boards and related sheet products must be less than or equal to 1.5mg/L. The large core board conforming to this standard is called E1 grade.
In the newly introduced national recommended standards, the formaldehyde emission of blockboard has increased the new E0 standard - formaldehyde emission is less than or equal to 0.5mg / L, can control the formaldehyde emission of wooden products, to reduce the room Pollution, protect consumers' health.
At present, there are many brands of blockboards in the market, most of which are E1 grade products. At present, only mainstream brands such as Tengfei, Penghong and Jinqiu have E0-class blockboards, and the unit price is only 20-30 yuan higher than the E1 products. Among them, the price of soaring is 138 yuan / Zhang, the price of Penghong is 148 yuan / Zhang, Jinqiu sellers said that there are E0 grade products but not available.
According to a brand technician, the price difference in the general blockboard market is a normal phenomenon, which is mainly determined by the cost of the board. The cost is high and the natural market price is high. The cost of the E1 grade first-class blockboard is about 60 yuan, the cost of the middle plate and the panel is about 30 yuan, and the labor cost is about 100 yuan, so the large core board consumption of more than 100 yuan in the market Purchase is more assured. The cost of the E0 grade blockboard will increase by about 30%, so when consumers buy E0 class blockboard, the price is more than 130 yuan.
At present, some environmentally friendly blockboards emit only 0.1mg/L of formaldehyde; the moisture content after drying is only 6%-8%; the precision of the core board can reach 0.1mm or less, and the panel is smoother and smoother.
