Abstract
The production method of the radial thin bamboo strip curtain composite plate includes the following steps: radial cutting bamboo material to make thin bamboo strips; making the thin bamboo strips into single bamboo strip curtain or bundle bamboo strip curtain by rolling and weaving, kiln drying by binding method, gumming, drying and combining it with wood single plate, bamboo mat and impregnating paper to form several kinds of composite structure plate blanks, then adopting once thermal plasticization-thermal gluing process or veneering hot-pressing or coating hot-pressing modes to obtain the products with different purposes. Said invented product possesses excellent property, can be extensively used in the fieds of concrete form and platform floor, etc.
Description
The invention belongs to the bamboo matter composite plate in wood-based plate field
At present, the manufacture method of bamboo matter composite plate generally adopts the tangential plate that composes of bamboo wood both at home and abroad.Owing to exist tabasheer, the bamboo strip that is difficult to glue together respectively at the tangential surfaces externally and internally of bamboo wood, in order to guarantee good gummed, surf green, yellow bamboo face must be rejected, this has not only increased manufacturing procedure, more greatly reduces utilization rate of bamboo.
The objective of the invention is for society provides a kind of utilization rate of bamboo height the bamboo matter composite plate that cost is low.This bamboo matter composite plate is mainly as concrete form, platform floor and container bottom board.
The present invention radially cuts open the thin bamboo strip with bamboo wood, and radial thin bamboo strip rolls and is made into single bamboo strip curtain or bundle bamboo strip curtain, the constraint method kiln drying of thin bamboo strips used for weaving curtain and adopts radially gummed, heat---and hot gluing technology and aftertreatment technology thereof are the bamboo matter composite board manufacture method of its feature.The manufacture method of radial bamboo splint composte board comprises the steps and process successively.
1, the manufacturing of radial thin bamboo strip curtain
The transversal one-tenth certain-length of A bamboo wood is rejected the acromere and the internal segment of bamboo wood respectively on knot borer.
B is to the bamboo wood of diameter less than 6cm, in rejecting behind the acromere, on the blue or green machine surf green brushed going.
C cuts open bamboo wood by break bar and to be whittled into the radial thin bamboo strip that both sides have surf green, tabasheer respectively on special Machine for radially slicing thin bamboo strips.The thickness of radial thin bamboo strip is 2.0～5.0mm.
D is for the radial thin bamboo strip of width greater than 7mm, rolls to be made into single flat thin bamboo strips used for weaving curtain that crouch, that thin bamboo strips used for weaving is parallel to each other and to be referred to as single bamboo strip curtain on special stitching machine.Less than 7mm and brush the radial thin bamboo strip of surf green, is a thin bamboo strip bundle with several thin bamboo strips used for weavings for width then, manually with radial line each thin bamboo strip bundle is woven into the thin bamboo strips used for weaving curtain that is parallel to each other then, is referred to as bundle bamboo strip curtain.
The drying of E single bamboo strip curtain and bundle bamboo strip curtain all adopts constraint kiln drying method.It is to be central shaft with holes and steel pipe rib, single bamboo strip curtain, bundle bamboo strip curtain is crimped onto on the steel pipe respectively, and it is fettered into the bamboo curtain splint volume.Bamboo curtain splint twists in pile in the dry kiln, carries out drying under certain temperature, damp condition, and making its moisture content is 8～16%.
The dried bamboo curtain splint of F rolls in the impregnation pond, and dipping concentration is 18～25% water-soluble phenolic resin adhesive, makes the outer surface of radial thin bamboo strip curtain evenly flood glue.
Bamboo curtain splint behind G impregnation volume once more in dry kiln the pile drying to make its moisture content be 8～18%.
2, the preparation of other materials
The preparation of A bamboo mat: the braiding of bamboo mat, drying, applying glue and predry technology thereof are identical with the processing technology of the used bamboo mat of existing compound plastic bamboo plywood.
The preparation of B impregnated paper: basic identical with the impregnated paper technology of existing compound plastic bamboo plywood, spread is 70～120%.
The preparation of C veneer: veneer is the common veneer of plywood factory, and thickness is that 1.5～3.0mm, length are 1000～1320mm, and veneer answers splicing to become whole.
3, assembly
According to the slab structure artificial several formation unit combination are become slab.When assembly, must make the radial thin bamboo strip of single bamboo strip curtain in slab, be in the flat state that crouches, surf green, the yellow bamboo face that makes its width both sides be difficult to glue together is in the non-gummed position of sheet material, and making cemented surface all is the radial longitudinal section of bamboo wood.The slab structure of radial bamboo splint composte board is different and different with processing technology according to product purpose, sheet metal thickness.
4, heat---hot gluing technology and aftertreatment technology
Because the product purpose difference, plate construction and difference in thickness are very big, so that its hot-pressing gluing technology and aftertreatment technology differ is also very big.Heat---hot gluing technology is that hot pressing temperature remains under 130 ℃～150 ℃ conditions, the composite plate blanks hot press of packing into is carried out segmentation pressurization, after the process certain hour composes plate, the gluing technique of release ejecting plate under the situation of not lowering the temperature, it is mainly determined by three parameters such as temperature, unit pressure and times.The aftertreatment technology of composite plate is the technology that the sheet material after the hot pressing is handled again.It comprises following three kinds of processing modes: first kind is to once moulding the post processing of sheet material again, and it is at ambient temperature, the sheet material after the hot pressing is carried out immediately the pressurized treatments of certain hour; Second kind is the post processing to the impregnated paper veneer base material, and it is with after the base material sanding, respectively disposes an impregnated paper on its two sides, carries out the veneer of hot pressing again and handles; The third is the post processing to the compartment board base material of filming, and it is with after the base material sanding, at its two sides brushing phenolic resin glue, after ageing or predry, carries out hot-pressing processing again to filming.
5, cutting edge and edge sealing
A cutting edge: on edging and trimming saw, carry out the vertical and horizontal cutting edge, make the plate face size of sheet material reach the requirement of regulation.
B edge sealing:, manually brush or spraying polyurethane varnish or other coating in four sides of sheet material.
The manufacture method of radial bamboo splint composte board is compared with the manufacture method of the compound plastic bamboo plywood of the tangential gummed that generally adopts at present, the advantage that have that utilization rate of bamboo height, adhesive consumption are few, pressing cycle short, output adds kind, energy consumption reduces can reduce product cost significantly.The product physical and mechanical property is good, can be used for fields such as concrete blinding, platform floor.
