very large damage. Third, the environmental performance of Daxin Ban Daxinban production process, the general use of formaldehyde-based adhesives, so the finished product will release more or less free formaldehyde, when the free formaldehyde content exceeds certain limits, will affect human health. Detecting the release of formaldehyde from the core board is a complicated process. The formaldehyde emission from the core board can be simply and initially determined by the following method. First, the unused Daoxin plate stacked in a small house, close the doors and windows, to be stored for some time after the observation room. If there is no pungent smell of nodules that the large amount of formaldehyde release board, the use will not affect human health; if the smell of a larger or tearing, the release of formaldehyde content of the core board may be higher. In response to the problem of formaldehyde in Da Xinban, the pore diameter of the internal pores of human blue is in the range of 0.27 to 0.98 nanometers and is arranged in a crystal. At the same time with weak electricity, formaldehyde, ammonia, benzene, toluene, xylene molecular diameter between 0.4 to 0.62 nm, and are polar molecules, with
