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.
Security pigment based on core-shell particles, and production method
The invention relates to a security pigment of core-shell particles, comprising a core based on a thermoplastic material, a shell based on a condensation polymer, and an organic or metalorganic feature substance present in dissolved or finely distributed form in the core, wherein the mass fraction of the shell amounts to more than 25%, preferably 50%, particularly more than 100%, in relation to the mass of the core. The invention further relates to a method for producing the core-shell particles and to value documents having the core-shell particles.

Viscosity modified formaldehyde-free binder compositions
Viscosity-modified carbohydrate binder compositions are described. The binder compositions may include a carbohydrate, a nitrogen-containing compound, and a thickening agent. The binder compositions may have a Brookfield viscosity of 7 to 50 centipoise at 20 C. The thickening agents may include modified celluloses such as hydroxyethyl cellulose (HEC) and carboxymethyl cellulose (CMC), and polysaccharides such as xanthan gum, guar gum, and starches.

CELLULOSIC ARTICLES MADE FROM CELLULOSIC MATERIALS AND METHODS THEREFOR
The invention relates to systems and techniques for manufacturing articles containing cellulosic material, a coupling agent, and a binder resin, and related processes of making and using the cellulosic articles. In particularly exemplary embodiments, the manufactured articles are door skins, sometimes known as door facings, and doors made from the door skins. The article contains a lipophilic cellulosic material, a coupling agent, and a binder. The coupling agent is believed to increase the hydrophilicity (wetability) of the lipophilic cellulosic material.
