Method for manufacturing high-density, middle-density and low-density boards by bamboo

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 [0001] The invention relates to a manufacturing method of a fiberboard, in particular to a method for making high-density, medium-density and low-density boards from bamboo. Background technique [0002] Existing bamboo fiber board manufacture method, all have record at home and abroad, as Chinese patent " manufacture method of bamboo fiber product " (patent No.: 95112830) and " a kind of production method of bamboo fiber board " (Zhi Li No.: CN98112681) just provide Known to use bamboo as the manufacture method of the fibreboard of raw material, but the method labor intensity of making bamboo fiber in the 95112830 invention is bigger, and also needs operations such as loading mold, and operation is more complicated. In the 98112681 invention, the cooking process and the drug soaking process were adopted. The drug soaking process added pesticide ingredients. In fact, in the manufacturing process, after the bamboo and wood were cooked and dried, the possibilit...

Problems solved by technology

[0002] Existing bamboo fiber board manufacturing methods are all on the record both at home and abroad, such as Chinese patent "Manufacturing method of bamboo fiber products" (patent No.: 95112830) and "a kind of "Production method of bamboo fiberboard" (Zhili No.: CN98112681) provides a method for manufacturing fiberboard using bamboo as raw material, but the method for making bamboo fiber in the 95112830 invention is labor-intensive, and also requires steps such as molding, and the operation is relatively complex

In the 98112681 invention, the cooking process and the drug soaking process were adopted. The drug soaking process added pesticide ingredients. In fact, in the manufacturing process, after the bamboo and wood were cooked and dried, the possibility of growing insects had been greatly reduced. After adding the adhesive , it is not easy to grow insects, the invention uses pesticides to add to the fiberboard, which will cause environmental pollution, and at the same time, if it is used for furniture, floors, decoration materials or office supplies, it will even endanger human health
