Description
Technical field
To the utility model relates to flaking (Strand) as primary raw material, produce facing composite container baseboard, belong to the wood-based plate manufacturing technology field in timber industry.
Background technology
Container manufacture requires that base plate has very high mechanical property, presentation quality, impact resistance and ageing-resistant performance.Because its strength character requires higher, the high-quality hardwood such as clone and A Bidong in the original tropical rain forest in the ground such as Indonesia, Malaysia is normally adopted to be peeled into veneer to produce container bottom board, taboo along with original tropical rain forest is cut down and is increased fast with domestic labor wage, finds the expectation that the container bottom board can carrying out the high non-glued board class of automated production efficiency is whole industry.
The production of current container bottom board is normally main raw material(s) with veneer, and automaticity is low, and required artificial many, efficiency is not high.Comparatively speaking, the automaticity of the production of oriented wood chipboard (OSB) is very high, the annual production of the OSB factory that Canada is newly-built is recently not less than 60 ten thousand steres, equipment is advanced, and the automaticity of production line is high, produce 65 ten thousand stere OSB factories per year, class Three produces only needs 120 employees, wherein plant maintenance personnel are more, and all the other monitor the whether normal employee of production line before mostly being screen.Therefore to develop with flaking (external professional term is for Strand) be main raw material(s), and container bottom board is development trend.Flaking in this patent is flat long narrow wood shavings (also known as oriented shaving, long narrow wood shavings), after juggle peels off bark, flat long narrow patch unit (Strand) is processed in the equipment such as ring flaker, its thickness is even, during processing, length is identical, and width differs, different with the adjustment of planing tool in chipper, not etc., its width is not more than 30mm to the width formed usually.The performance of the oriented wood chipboard be made with flaking can design, and the shear behavior in intermediate layer also can design as required.This just provides good basis for making high performance oriented wood chipboard.Also possibility is provided for making high performance composite container baseboard.
Because the intensity of container bottom board and elastic modelling quantity require higher, therefore main is that raw material still have very high challenge difficulty to manufacture experimently container bottom board with flaking.The utility model adopts different structural designs and heat pressing process, one-shot forming can obtain qualified production board, in addition can also by utilizing existing oriented shaving board assembly line, the mode of secondary veneer is adopted to obtain required facing composite container baseboard, its surface quality attractive in appearance, and the unapproachable intensity of conventional container base plate.And have that production automation degree is high, efficiency is high, less energy consumption, the feature such as wear-resisting, and sustainable fast growing wood and bamboo wood that china natural resources is abundant can be utilized to produce container bottom board, widen the source of base plate material, there is far-reaching realistic meaning.
Summary of the invention
The purpose of this utility model is to provide the facing composite container baseboard that one is primary raw material with flaking (Strand).Its objective is anti-shearing, the high elastic modulus oriented shaving layer that utilize sandwich layer, because the high shear of overall sandwich layer, high elastic modulus and intensity are high, thus make the elastic modelling quantity of base plate and strength ratio higher, and top layer finish coat has the advantages that expansion rate of water absorption is low, hardness is high and wearability is good, sandwich layer is have the oriented shaving compared with high shear performance, finish coat is the material such as resin impregnated material and veneer, bamboo curtain splint and bamboo bundle curtain, can be used alone or compound use.This resin impregnated material can phenolic aldehyde or melamine impregnated paper, or phenolic impregnated glass fabric or non-woven fabrics.Bamboo bundle curtain is after thick bamboo tube cuts open into two panels, by the multiple flat blade on nip roll, tabasheer, surf green are punctured, to shoot off after flattening surf green, and with chopper, tabasheer part compartition is gone, or by fixed thick planing, obtain uniform thickness bamboo bundle, it woven with line or is knitted into required width, namely obtaining the bamboo bundle curtain of uniform thickness.
Technical solution of the present utility model: facing composite container baseboard, its structure comprises with flaking (Strand) 3 ~ 5 layers of directed flaking layer that are raw material for sandwich layer, and upper following table backing layer is finishing material; The finishing material of described upper layer is one deck resin impregnated material, inwardly to the uniform thickness bamboo bundle curtain being called one deck cross grain Wooden veneer and two-layer longitudinal texture; Or the finishing material of upper layer is one deck resin impregnated material, inwardly there is one deck cross grain bamboo curtain splint to being called in the middle of two layers of longitudinal texture bamboo curtain splint; The flaking of the directed flaking layer of described sandwich layer 3 ~ 5 layers adopts the mass ratio of bamboo flaking and wooden plane sheet to be (0 ~ 100): (100 ~ 0), the thickness of flaking is 0.5 ~ 1.0mm, and length range is 40 ~ 180mm.
Advantage of the present utility model: the artificial forest wood resource of China's fast-growing and continuable bamboo timber resource can be effectively utilized.Use after these Material claddings, through design and the reasonably combination of science, both can solve the difficulty that in world wide, hardwood is in short supply, the technical barrier producing to meet the Novel bottom plate that trans-container industrial technology requires in enormous quantities can be solved again.With high shearing resistance and the high flaking of elastic modelling quantity for main raw material(s), directly and finishing material mat formation assembly good after once hot-forming; Or first make oriented wood chipboard, then secondary facing processing.Finish coat is the material such as impregnated material and veneer, bamboo curtain splint and bamboo bundle curtain, can be used alone or compound use.This facing composite container baseboard has the features such as production automation degree is high, efficiency is high, less energy consumption, intensity are high, wear-resisting and attractive in appearance, meets the technical requirement of trans-container industry.
