Description

With thick bamboo matter unit combination layer be top layer composite container baseboard and manufacture method
Technical field
The present invention relates to a kind of with thick bamboo matter unit combination layer be top layer composite container baseboard and manufacture method, belong to the wood-based plate manufacturing technology field in timber industry.
Background technology
Container manufacture requires mechanical property, presentation quality, impact resistance and the antiseptic property that base plate is higher.Owing to its mechanical property requirements is higher, the high-quality hardwood such as clone and A Bidong in the original Tropical rain forest in the ground such as Indonesia, Burma is generally adopted to be peeled into veneer to produce container bottom board, enhancing along with whole world environmental consciousness, a lot of countries implement the taboo of original Tropical rain forest and cut down, meanwhile the quick-growing plantation resource of China quickly increases, such as Eucalyptus, willow, Pinus massoniana Lamb and bamboo grove etc., the container bottom board finding non-torrid zone hardwood plywood class is the expectation of whole industry.
The production of current composite container baseboard is usually with bamboo curtain splint, bamboo mat for main raw material(s), and automaticity is low, required artificial many, inefficient.Comparatively speaking, owing to bamboo mat and bamboo curtain splint mostly are the manual processing of family workshop type, formation efficiency is low, product became uneven, width differ, and the processing and fabricating of bamboo wood is loaded down with trivial details, and raw-material buying is subject to seasonal restrictions.When purchasing in a large number, raw material supply is not gone up, and which limits manufacture high-performance composite container baseboard.
Now by a kind of processing mode, circle bamboo is rolled after leveling through room temperature, brush away or plane or split the yellow and wide processing of outer of bamboo that impact is glued, the bamboo chip thickness so obtained is thicker, wider width, and one layer of bamboo of its horizontally-spliced one-tenth is spelled material plate, mechanical property plus such bamboo kind is higher, applies it to top layer, it is possible to play its advantage mechanical property of entire plate being substantially improved at sheet material table backing layer.Also have glue consumption when manufacturing few, it is simple to the cost control of container bottom board.The sustainable domestic bamboo timber that such available resources enriches produces container bottom board, has widened the source of base plate material, has had far-reaching realistic meaning.
Summary of the invention
What the present invention proposed is a kind of with thick bamboo matter unit combination layer be top layer composite container baseboard and manufacture method, day by day rare for the high-quality hardwood resource in existing container bottom board technology, and bamboo mat and bamboo curtain splint mostly are the manual processing of family workshop type, production efficiency is low, the quality of product is low, and the processing and fabricating of these two kinds of bamboo materials is loaded down with trivial details, buying is subject to seasonal restrictions, and have the shortcomings such as bamboo green grass or young crops and Concretio silicea Bambusae seu schizostachyi, there is provided the large format of a kind of splicing without the blue or green bamboo jigsaw rolling leveling without yellow room temperature, it is used as the table back of the body combination layer material of composite container baseboard, the material such as artificial forest wood and bamboo wood of compound fast-growing makes composite container baseboard again.
The technical solution of the present invention: a kind of be top layer with thick bamboo matter unit combination layer composite container baseboard, its structure is that base arrangement includes upper epidermis, layer and the sandwich layer being located between upper epidermis and layer, wherein upper epidermis and layer are the combination layers with bamboo jigsaw and veneer, and sandwich layer is longitudinal veined wood veneer and cross grain veneer, longitudinal texture bamboo jigsaw, longitudinal texture improve one or more overlappings rolled in thin bamboo strips used for weaving curtain, structure flakeboard.
Its manufacture method, comprises the technical steps that:
A, bamboo jigsaw, veneer, improvement roll thin bamboo strips used for weaving curtain and the sorting of structure flakeboard and arrange, and bamboo jigsaw and improvement roll thin bamboo strips used for weaving curtain and is dried to moisture content less than 10%, improve and roll after thin bamboo strips used for weaving curtain is through impregnation with phenol glue, and cold drying is to moisture content 12～18%；Veneer drying is to moisture content≤10%, double spread phenol glue；Structure flakeboard sanding is to 22mm, double spread phenol glue, and glue-spread is 180g/m2(two-sided), adds the insecticide of 2.4 grams by 1 kilogram of glue (solid content 45%) in glue；
B, assembly and hot pressing, using bamboo jigsaw combination layer as table backing layer, sandwich layer is veneer, bamboo jigsaw, improves and roll thin bamboo strips used for weaving curtain and structure flakeboard assembly；Then it is 135～145 DEG C in temperature, when maximum pressure is 1.8～3.0MPa, carries out hot pressing, keep 15～35 minutes, then steam discharge, blood pressure lowering and release.
Advantages of the present invention: with bamboo jigsaw combination layer for table backing layer, raw material production efficiency is high, quality is good, supply is stable, adds that the mechanical property of such bamboo sheet is higher, applies it to top layer, and the mechanical property of overall sheet material is substantially improved.Adopting adjacent layer veneer gluing, eliminate the loaded down with trivial details technique that bamboo wood elder generation impregnation is dried again, heat pressing process adopts heat to enter the high efficiency production mode that heat goes out, and has the advantage that production cost is low.Resourceful sustainable domestic bamboo timber so can be utilized to produce container bottom board, widened the source of base plate material, there is far-reaching realistic meaning.
