Abstract
The invention discloses a production method of bamboo plywood, comprising the following steps of: (1) preparing dry bamboo curtain splints; (2) soaking bamboo curtain splints in glue, wherein the glue is phenolic resin glue; (3) dehumidifying the glue-soaked bamboo curtain splints; (4) assembling the dehumidified bamboo curtain splints; and (5) curing in a hot-press way. The production method has the advantages that (1) compared with the conventional heat drying means, the dehumidifying means is used for drying the glue-soaked bamboo curtain splints, so that the possibility that the thermosetting type glue is cured when the heat drying process is carried out can be eliminated due to the fact that the dehumidification is carried out under 38 DEG C, so that the bonding performance of the bamboo plywood is ensured; (2) compared with the drying technology, the dehumidifying drying technology eliminates the influence of the drying technology to the product quality caused by uncertain factors, i.e. the air relative moisture content, the raw material dryness and the like, so that the dryness of the bamboo plywood glue-soaking material can be effectively controlled, and therefore, the aim of guaranteeing the product quality can be achieved; and (3) the labor intensity of workers can be reduced, and the productivity can be improved.
Description
Technical field
The present invention relates to a kind of production method of bamboo plywood, specifically a kind of glue that can retain completely is active and improve the production method of bamboo slab rubber glue performance.
Background technology
Bamboo slab rubber decides with mao bamboon material to want framework and packing material, is pressed into the sheet material of base hot setting through height.Bamboo slab rubber has hardness high, anti-folding, compressive resistance is strong, anti-wear performance is good, the features such as expansion rate of water absorption is low, main application has: building template, concrete segment (brick) are produced to be needed to use sheet material with bamboo glue supporting plate, truck body box plate and box plate, railroad car boxboard and base plate, container plate, the freezing deck of boat, decoration bamboo flooring and other various being correlated with.Again because bamboo wood is easy to cultivate, within 4 years more than, just can cut down, become a useful person fast, therefore, wood substituted by bamboo is national policy support and the guiding greatly developed of requirement, and the manufacture of bamboo slab rubber to apply be the most concentrated expression of wood substituted by bamboo bamboo;
Mao bamboon is normally first processed into bamboo mat or bamboo curtain splint by prior art, bamboo mat or bamboo curtain warp element oven dry-impregnation-dry again-assembly-hot-press solidifying becomes plate, because the phenolic resin glue adopted is heat curing-type glue, after impregnation bamboo curtain splint again oven dry glue can be made to cause glue survival rate to reduce because of heat cure; Cause the glue performance of produced bamboo slab rubber poor.Therefore, present part producer replaces drying with drying, but dries very slow, and the humidity of drying rear impregnation bamboo curtain splint can not accurately control.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention discloses a kind of production method of bamboo plywood, the activity of dehydration can be retained completely, thus the glue performance of bamboo slab rubber can be significantly improved.
Present invention employs following technical scheme:
A kind of production method of bamboo plywood, is characterized in that, comprise the following steps:
(1) bamboo curtain splint that preparation is dry;
(2) by bamboo curtain splint impregnation, glue used is phenolic resin glue;
(3) to the bamboo curtain splint dehumidifying of impregnation;
(4) by the bamboo curtain splint assembly after dehumidifying;
(5) hot-press solidifying.
As preferably, in step (1), the moisture content controlling bamboo curtain splint, lower than 10%, guarantees that bamboo curtain splint has evenly enough suction glue amounts.
As preferably, in step (2), the solid content of described phenolic resin glue is 20% ~ 40%; The rational glue consumption of effective control.
As preferably, in step (3), temperature controls below 38 degree, to retain the activity of glue completely; Also be the temperature requirement that dehumidifier normal safe uses simultaneously.
As preferably, in step (3), by bamboo curtain splint dehumidifying to moisture content less than 15%.
As preferably, in step (3), dehumidify in the following way: the bamboo curtain splint rolled closely is stood up, dry air from upper from lower, pass from bamboo curtain splint and bamboo curtain splint, small spaces between bamboo chip and bamboo chip, fully contacts with every sheet bamboo chip, take away the moisture content in bamboo chip, reach the object of desiccant dehumidification.
As preferably, step (3) adopts dehumidifying room to dehumidify, and is provided with dehumidifier, airduct and material table in the dehumidifying room closed;
Dehumidifier is located at dehumidifying one end, room; Material table and dehumidifier keep setpoint distance, and the both sides of material table are near dehumidifying both sides, room inwall;
Keep setpoint distance and be densely covered with passage bottom material table and dehumidifying room; Material table is provided with abat-vent near one end of dehumidifier, is provided with opening at the other end;
One end of airduct is located at dehumidifier air outlet place, and the other end connects with opening, is provided with driving blower fan in airduct.
Further, described dehumidifier air outlet place is also provided with radiator, and dehumidifier for a long time running can make the temperature in dehumidifying room raise, and can affect the activity of glue in bamboo curtain splint on the one hand, also can affect the service life of dehumidifier on the other hand, the effect of radiator is exactly reduce temperature.
The operation principle in this dehumidifying room is as follows: by rolled-up impregnation bamboo curtain splint, closely stand up on material table; Dry air in dehumidifier enters airduct, under the effect driving blower fan, flows into below material table via opening; Owing to being subject to the stop of deep bead, dry air is upwards flowed by the passage of material table, and upwards flows along bamboo curtain splint and bamboo curtain splint, fine and closely woven space between bamboo chip and bamboo chip, takes away the moisture content in bamboo curtain splint simultaneously; The dehumidified machine of humid air sucks, and again becomes dry air; Circulation like this, reaches the object of dehumidifying.Air humidity in dehumidifying room, i.e. the moisture content of bamboo curtain splint, when being reduced to setting level, dehumidifier enters battery saving mode.
The invention has the advantages that:
(1) adopt dehumidifying means to the bamboo curtain splint after impregnation carry out dry to dry with traditional heat compared with, because dehumidifying is carried out below 38 degree, eliminate the possibility of heat curing-type glue glue curing in hot drying course, thus the glue performance of bamboo slab rubber is guaranteed;
(2) removal moisture drying with dry compared with technique, eliminate and dry technique because the uncertain factors such as air relative moisture content and raw material drying degree are on the impact of product quality, effectively can control the aridity of bamboo slab rubber impregnation material, thus reach the object ensureing product quality;
(3) reduce the labour intensity of workman, improve productivity ratio.
