At present, in the market, there is a proportion of local artificial slate containing excessive amounts of harmful substances such as benzene, formaldehyde, lead, organic acids, etc. A common characteristic of such plates is the pungent chemical odor (especially during processing) The color is an unnatural chemical color. This inferior artificial stone plate containing formaldehyde and benzene will give off a pungent odor when it is cut.
After the plate is processed and processed, the excess formaldehyde and benzene will remain. Benzene will be volatilized continuously for 3-5 years. The volatilization of benzene and formaldehyde and exposure to heavy metals will directly contaminate imported foods. This harmful substance not only passes through the human respiratory system but also directly enters the digestive system. And the speed is more significant.
Therefore, it is especially important to choose artificial stone with excellent quality. In the winter, especially in the north, the air is not fluent at home, and the indoor temperature is higher, which will accelerate the volatilization of such "toxic board" benzene and formaldehyde, and damage the human body. More serious!
