In the production process of Lu Liwood ,non-formaldehyde adhesive (MDI adhesive)is used to replace the urea-formaldehyde resin adhesive produced by mixing formaldehyde with urea in a certain molar radio .Because formaldehyde is not added ,free formaldehyde VOC and other toxic and harmful gases would not be generated during the use of plates .

ormaldehyde is a kind of colourless and soluble irritant gas which is harmful to human body .Wood products made with formaldehyde adhesive are used indoors and the formaldehyde release period can be up to 8-15 years .

The technology of zero aldehyde addition has been used in the production of wood-based panel and furniture building materials .At present ,the main adhesives for zero-formaldehyde are formaldehyde free MDI glue and soy protein glue ,which are used in the production of environmentally friendly furniture boards .
