TH8856A - Method for bonding lignocellulosic materials with a gas ester - Google Patents

Abstract

Has disclosed about a method for securing cellular materials under heat. And the pressure combined with water vapor And gas ester, according to the method, have compacted the cellulose material sheet with Alkali solution In the curing water as a feed binder Non-Formaldehyde Resol Between the first pair of hot presses, the density and thickness between the And inject steam at Condensation enters the sheet through the opening in the bending platform, then compresses the sheet again to its density. And the final thickness And inject a gas ester into the plate to harden Part of the binder After the gas ester is injected, another high-pressure steam may be injected into the plate. To induce further hardening or to get rid of non-hardened formaldehyde, a vacuum or gas may be released from the plate through the opening of the press to Get rid of excess steam and other fumes and turn on the compressor to remove The planks are made of sheets from the press.

: Revealed about a method for securing cellular materials under heat. And the pressure combined with water vapor And gas ester, according to the method, have compacted the cellulose material sheet with Alkali solution In the curing water as a feed binder Non-Formaldehyde Resol Between the first pair of hot presses, the density and thickness between the And inject steam at Condensation enters the sheet through the opening in the bending platform, then compresses the sheet again to its density. And the final thickness And inject a gas ester into the plate to harden Part of the binder After the gas ester is injected, another high-pressure steam may be injected into the plate. To induce further hardening or to get rid of non-hardened formaldehyde, a vacuum or gas may be released from the plate through the opening of the press to Get rid of excess steam and other fumes and turn on the compressor to remove Plank made of sheets from the press release machine (item one), which will appear on the noticeboard: method for preparing planks from sheets of lignocellulosic materials and alkaline binders. Phenolic Resol It consists of: 1. (a) Placing the sheets between the presses of the press Where at least one of the presses has holes in the surface. The face of it that is opposite the other platform For a channel And (b) the compression of the plates between the presses and the injection of an ester that is A gas with a boiling point of approximately 85 or less is added to the plate. From the opening in the platform To harden the binder 2. Method of claim 1 where the podium is tagged:
