Example Embodiment
[0051] Example one
[0052] a. Substrate sanding: Use a three-sand frame sander to sand the surface of 18mm ordinary poplar plywood, and the third sanding belt is 180 mesh. Measure the thickness error, the maximum error is 0.11mm. Observe the surface finish, the surface is smooth and clean, without wavy lines;
[0053] b. Formaldehyde decomposition glue preparation: fully mix and stir the effective components of formaldehyde decomposition and amino resin to obtain formaldehyde decomposition glue; the mass ratio of the effective components of formaldehyde decomposition in the formaldehyde decomposition glue is 5%, and the stirring time is 5 minutes; formaldehyde decomposition is effective Ingredients include chitin, nano silicon wafers and tourmaline powder; tourmaline powder accounts for 1wt% of the mass of the effective ingredients for formaldehyde decomposition;
[0054] c. Decorative adhesive film paper manufacturing: the decorative paper is passed through amino resin glue and f...
Example Embodiment
[0060] Example two
[0061] a. Sanding the base material or applying veneer: Use a three-sand frame sander to sand the 16.5mm blockboard core, and the third sanding belt is 200 mesh. The thickness error is measured, and the maximum error is 0.22mm. Observe the surface finish and roughness. A layer of poplar veneer with a thickness of 0.5mm is covered on the surface, and the moisture content of the veneer is 10%. And sanding to a smooth surface;
[0062] b. Formaldehyde decomposition glue preparation: fully mix the effective components of formaldehyde decomposition and amino resin and stir uniformly to obtain formaldehyde decomposition glue; the mass ratio of the effective components of formaldehyde decomposition to formaldehyde decomposition glue is 10%, and the stirring time is 10 minutes; formaldehyde decomposition is effective Ingredients include chitin, nano silicon wafers and tourmaline powder; tourmaline powder accounts for 3wt% of the mass of the effective ingredients in ...
Example Embodiment
[0069] Example three
[0070] a. Sanding of the substrate: the substrate is a blockboard core or plywood; if the surface finish of the blockboard core or ordinary plywood substrate is poor or the thickness error exceeds 0.15mm, the surface needs to be covered with another layer of thickness 0.7mm, containing water Whole veneer with a rate of ≤5%, the veneer is usually poplar veneer or reorganized decorative veneer;
[0071] b. Formaldehyde decomposition glue preparation: fully mix and stir the effective components of formaldehyde decomposition and amino resin to obtain formaldehyde decomposition glue; the mass ratio of the effective components of formaldehyde decomposition in the formaldehyde decomposition glue is 6%, and the stirring time is 8 minutes; formaldehyde decomposition is effective Ingredients include chitin, nano-silicon flakes and tourmaline powder; tourmaline powder accounts for 5wt% of the mass of effective components in formaldehyde decomposition; the mass ratio of ...
