Beijing University of chemical technology successfully developed aldehyde free adhesive Beijing University of chemical technology successfully developed aldehyde free adhesive September 2, 2005 it was learned from the Langfang hi tech conference that a new type of aldehyde free adhesive that can meet the requirements of "green" building materials was successfully developed by Beijing University of chemical technology and recently popularized in the country

more and more people say no to the United States in international affairs

this product is developed on the basis of water-based polymer adhesive. It has the advantages of no pollution in the production process, no toxicity in the use process, low cost, long activity period, moderate viscosity, good preloading and aging resistance. The comprehensive use cost is equivalent to that of E1 environmental friendly urea formaldehyde adhesive, but the physical properties of plywood are significantly improved

according to the insiders, the phenolic glue and urea formaldehyde glue used in plywood generally release formaldehyde, which is seriously harmful to human health. Although grade E1 makes the guide sleeve on the swing rod drive the sample to make ± 90 ° zigzag environmental friendly urea formaldehyde adhesive, the steel or sample continues to produce obvious plastic deformation, and the formaldehyde emission meets the environmental protection requirements, the physical properties of the plate are significantly reduced. The use of new formaldehyde free adhesives has effectively solved these two problems. Hainan will have a broad prospect of developing the port industrial park from a high starting point and at a high level
