Abstract

The invention discloses a gum leakage process technology of bamboo-wood rods with high water content. The method comprises the following steps: 1) taking the bamboo-wood rods with high water content for carbonizing, bleaching and the like, putting the bamboo-wood rods into a pressure vessel, and separating bamboo-wood bundles with partition bars to assure a certain space, thus guaranteeing gum solution flowing; 2) carrying out vacuum bulking treatment at a vacuum pressure of 0.070-0.09MPa, wherein, a preferred pressure is 0.078MPa and system vacuum time is 20-60min, and determining specific vacuum time combined with thickness of the bamboo-wood rods; 3) carrying out gum leakage by diffusion; 4) carrying out vacuum drainage treatment; and 5) taking out the bamboo rods after gum leakage. Theprocess in the invention helps avoid the procedure for drying the bamboo-wood rods before gumming, and only the drying process after gumming is required, thus simplifying the process, solving the problem of conventional dry bamboo-wood rods such as uneven gumming, realizing stable and even product performance, and saving production cost of the drying procedure before gumming including labor wage,electric energy and dried water evaporation heat energy unit about **/m<3>.

Description

technical field [0001] The invention relates to the field of bamboo wood processing, in particular to a glue seeping technology widely applicable to the processing of bamboo wood recombined wood and laminated wood using water-soluble glue as an adhesive. Background technique [0002] At present, the impregnation process for the production of recombined bamboo wood and glulam generally adopts bamboo strips to be dried and then put into the impregnation pool for soaking and impregnation. This method generally needs to dry the high moisture content bamboo strips with a moisture content of 50-60% after carbonization, bleaching, etc. to a moisture content of less than 12%, and then dip them in glue under normal pressure conditions. Bamboo and wood strips are dipped in glue by the adsorption of dried bamboo and wood strips to glue, and the amount of glue dipping is controlled by controlling the concentration of glue and soaking time. After dipping in this way, the bamboo strips a...
