Method for quick hot-press forming of laminated wood
The present invention discloses a method for quick hot-press forming of laminated wood. The method includes: drying a machined small wood material to a moisture content of 5-8 wt %; gluing the dried small wood material, and assembling and laying the dried small wood material to be a square material or a sheet material, where an adhesive for the gluing is a water-soluble adhesive having a solid content of 45-60 wt %; clamping the square material or the sheet material through a three-dimensional metal clamp; sending the clamped square material or sheet material together with the clamp into a microwave heating machine for microwave heating to obtain a formed laminated wood, where the time from the gluing to the entry into the microwave heating machine is controlled to not exceed 15 min. According to the present invention, a glued part that needs to be heated can be heated quickly, precisely and effectively, the gluing strength and production efficiency of the laminated wood can be significantly improved, and the cost of production energy consumption is reduced.

UREA-GLYOXAL CROSSLINKING COMPOUNDS FOR PHENOLIC BINDER COMPOSITIONS
Binder compositions are described that include a phenol, a urea compound, formaldehyde, and at least one cyclic urea-dialdehyde compound. The cyclic urea-dialdehyde compound forms crosslinking bonds between polymers of phenol-urea-formaldehyde when the binder composition is cured. Also described are methods of making fiberglass insulation products using the above-described binder compositions. The methods may include contacting the binder composition with glass fibers and forming an amalgam of the binder composition and the glass fibers. The amalgam may be heated to form mats of the glass fibers and binder. The mats may be processed into the fiberglass insulation products.
