Description
Technical field
type of the present invention relates to a kind of high strength anti-deformation wood composite gate production technology, particularly relates to preparation method and the structure of Environment-friendlyhigh-strength high-strength anti-deformation wood composite gate.
Background technology
because the former forest reserves of China are faced with the predicament reduced year by year, Caiyu is lacked of proper care, and causes wood supply amount very in short supply.Therefore national correlation department pays much attention to the problem of saving timber resources, although country is in enforcement wildwood protected project, has progressively accomplished that forest cut reduces year by year; but the timber felled; but do not accomplish effectively to make full use of, timber resources has occurred that demand is large, the problem that cost is high.
but by the rapid-result woods of artificial growth as: the Chinese parasol tree tree of limit, road willow and every place of the village, paulownia now become a useful person, but people often use it for rudimentary purposes, not as fuel combustion, be made into glued board, use it for the single use such as external packing, building template exactly, utilization rate is extremely low, wastes the resource of timber greatly.
current plywood factory, veneer factory, multi-layer sheet factory are in process, part veneer secondary veneer, three grades of veneers or veneer, because became uneven, color exception, the factor purposes such as too much that scabs are little, a part is used for low level plywood single use, a part is as waste deposit corner, often finally to worry because can not find customer resources, of long duration can moldy metamorphism, can only burn as burning material, not only pollute environment, also waste timber resources greatly, improve raw-material cost.
Summary of the invention
the present invention is directed to the problem that rapid-result woods utilization rate is extremely low, secondary veneer, three grades of veneers or veneer, because of became uneven, color exception, the problem that the factor purposes such as too much that scabs is little, provide a kind of preparation method of Environment-friendlyhigh-strength high-strength anti-deformation wood composite gate, can solve the problem preferably, fabrication techniques process and unique structure of employing science take the lead in having broken through above-mentioned technical barrier. thus not only make use of waste wood, make it turn waste into wealth, also greatly reduce cost, expand the competitiveness in market, a large amount of timber forest reserves are saved, protect ecological environment.
a preparation method for Environment-friendlyhigh-strength high-strength anti-deformation wood composite gate, comprises the following steps:
first log is carried out sofening treatment by the first step, then carries out microminiaturization process and makes veneer;

the invention has the beneficial effects as follows: instant invention overcomes traditional natural drying means and make veneer moisture content high, poor flatness; Drum-type drying method makes veneer warpage modification serious cracking, is difficult to the problem of ensuring the quality of products, and adopts the flatness of heat pressing type seasoning veneer to be better than the quality of additive method oven dry.
the heat pressing type seasoning that the present invention adopts ensures veneer flatness at present, eliminate internal stress, the way of dry mass the best, the flatness of veneer and dry mass are one of key factors of multi-layer sheet quality, and it not only serves effect that is dry and pressing veneer and the more important thing is the effect serving preliminary setting; This method is far superior to conventional drying process.Heat pressing type seasoning.
because the hot strength of rift grain stretching resistance=40 times band, so the balanced pulling force plate that the present invention adopts (splicing of the horizontal veneer of grain direction and setting) prevents multi-layer sheet to expand or shrinks; Prevent multi-layer sheet lateral bending deformation; Multi-layer sheet is prevented to ftracture.
water resistance of the present invention is very good, and the multi-layer sheet after synthesis does not come unglued through boiling water boiling for 32 hours, the bubble that oozes through cold water does not ftracture for 168 hours.
pressure in HTHP heat treatment of the present invention, temperature, the time further enhancing the stability of timber, improves the density of timber, makes multi-layer sheet more solid.
the present invention is made up of the solid wood veneer plate of 100%, sound insulation, heat insulation, every cool Be very effective, it compensate for the deficiency of solid wood board, finger-jointed plate, density board, particieboard, core-board, solve furniture, decoration ornament materials and timber core material not environmentally, non-watertight, non-moistureproof, sleeping nail property is poor, it also solves the problem that some solid wood boards in core material and timber exist flexible type cracking simultaneously, has filled up China's technological gap.The plate using the present invention to make and door are relative to composite and doors such as existing gluing solid wood board, wood-based plates, the at least 5-10 effect doubly that increases the service life can be reached, the present invention will become best anti-deformation multi-layer sheet and door, quality is extremely stable, cheap, of many uses, be more conducive to applying of existing market.
