without formaldehyde timber flooring

Formaldehyde is a chemical gas, the air content of a certain concentration, it will harm the human body. Long-term living in the formaldehyde concentration exceeding the environment, the human eye, nose, respiratory system may suffer significant injury, or suffering from skin diseases. Animal experiments showed that excessive formaldehyde emission can also lead to nasal cancer and respiratory system cancer. Formaldehyde in laminate flooring is mainly produced in the manufacturing process from the role of formaldehyde resin adhesive. This resin adhesive strong, strengthen the hardness of the plate, pest control, anti-corrosion function and cheap, is currently the preferred man-made sheet of glued materials. As the formaldehyde contained in the floor will not evaporate immediately, but because of different temperature and humidity conditions, volatile slowly, volatile time for more than a decade. therefore, countries on the formaldehyde emission of plywood products have developed strict standards , Such as Japan, the European Union are required per 100 grams of plywood formaldehyde emission must be less than or equal to 10 mg, or not allowed to market; China's formaldehyde emission limit (GB18580-2001) provides: laminate flooring formaldehyde emission must be less than Or equal to 1.5 mg / l, can be directly used indoors."
