Abstract
The invention discloses a method for manufacturing high-density, middle-density and low-density boards by bamboo. Manufacturing raw materials include bamboo or bamboo and wood mixture. Manufacturing processes include cutting, digesting, hot grinding, binder applying, drying, forming, prepressing and hot pressing. The method has the advantages that the problem of raw material shortage caused by the fact that existing fiber boards (including middle-density fiber boards, high-density fiber boards and low-density fiber boards) are all made of three-waste wood materials is solved, and vast forest farms and bamboo resources in rural areas can be utilized fully. The method is simple and easy to operate; the boards manufactured by the method are safe and environment friendly, and are applicable to manufacturing of furniture, office appliances, decorations, ships, teaching equipment, floor boards, door skins, skirting lines or packaging and the like.
Description
Technical field
The present invention relates to a kind of manufacture method of fiberboard, particularly a kind of bamboo wood is made the method for high density, middle density, low-density plank.
Background technology
Existing bamboo fiber board fabrication method, all on the books both at home and abroad, 95112830) and " a kind of production method of bamboo fibreboard " (sharp number of will: CN98112681) just provide and use bamboo wood to be the manufacture method of the fiberboard of raw material such as Chinese patent " manufacture method of the bamboo fibre products " (patent No.:, but the method labour intensity of making bamboo fibre in 95112830 inventions is larger, but also the operations such as needs dress mould, the operation more complicated.Cooking process and drug immersion operation have been adopted in 98112681 inventions, the drug immersion operation adds farm chemical ingredients, and in fact in manufacture process, bamboo and wood is behind boiling, drying and processing, the possibility of its snake reduces greatly, behind the adding adhesive, more is difficult for snake, this invention uses agricultural chemicals to add in the fiberboard, can cause environmental pollution, as being used for worker's furniture, floor, decorating and renovating material or office appliance etc., more can be detrimental to health simultaneously.
Summary of the invention
Purpose of the present invention namely is to overcome the prior art shortcoming, provide a kind of manufacturing process rationally, the bamboo wood of safety, environmental protection make high density, middle density, low-density plank method with, it is cheap for manufacturing cost, raw material is easy to get.
The object of the invention is achieved through the following technical solutions: bamboo wood is made the method for high density, middle density, low-density plank, and manufacturing process is:
(1) boiling: fritter greenwood or fritter bamboo wood and timber mixture are put into the boiling cylinder with 120 ℃ of-180 ℃ of thermophilic digestions, make bamboo wood softening, be easy to defibrator process;
(2) defibrator process: will soften bamboo wood or bamboo wood mixture and put into defibrator and be milled into very thin fiber, being about 8 millimeters, diameter is the about 0.5 millimeter silk of human hair thickness;
(3) applying glue: to fiber coating glue;
(4) drying: will be coated with the fiber oven dry of glue, heat baking temperature is 120-160 ℃;
(5) moulding: the fiber lay down that is coated with glue that will dry with extravagant machine installs, and again through mitre saw, is sawn into slab;
(6) hot pressing: with hot press slab is pressed into long 2.6 meters, wide 1.35 meters, the semi-finished product of thick 2-3.2 millimeter, hot pressing temperature is 130-160 ℃;
(7) deposit 72 hours;
(8) finally by sanding, sawing grow up 2.44 meters, wide 1.22 meters, thick 2.28 millimeters production board.
Used fritter bamboo wood is bamboo cutting for sheet or collects the bamboo slag or the Erhuang thin bamboo strip is cut.
Spraying glue is phenolic resins, Lauxite or melamine resin.
According to hot pressing pressure from big to small scale go out high density, middle density, low density fiberboard.
Can find out by top narration, the present invention has the following advantages: solved that present fiberboard is done raw material with timber three wastes village merely and the problem that causes that there is lack of raw materials, can take full advantage of vast forest farm, the abundant bamboo resource in rural area, preparation method of the present invention is simple, manufacture craft easy operating, safety, environmental protection, no matter all very suitable as Furniture manufacture, office appliance, decorations, boats and ships, teaching equipment, floor, door skin, skirting or packing etc.The bamboo color is good, and is indeformable, and density is moderate, and the modes such as machining property is good, can saw, follow closely, fluting, mortise are processed arbitrarily.
