Problems solved by technology

[0003] With the reduction of wood resources, it is imperative to use crop straw instead of wood to produce wood-based panels, but how to develop a technical method that is high in strength and low in cost and suitable for large-scale industrial production is very important. The straw is pulverized, mixed with glue, and hot-pressed to form it. The plate strength produced by this process method is relatively low. The core technology disclosed in the method for making laminated materials from sunflower stalks (CN1067400A) is to split the sunflower stalks, and then peel and peel them. Add some additional materials, such as bamboo skin, steel mesh, etc., to the sunflower stalks before loading the mold. Although the boards made can replace wooden boards, the process is cumbersome and the cost of the boards is too high; a method of using straw to make boards ( CN1383966A) all the stalks used must be cracked, the skin and core removed, braided into sheets with wire ropes, and then three to nine sheets are stacked together, and the directions of adjacent sheets are laid crosswise. The process is too complicated and is not conducive to large-scale industrial production

Embodiment 1

[0017] First, one of sunflower stalks, flue-cured tobacco stalks, corn stalks, sorghum stalks, and rapeseed stalks is sent into the wood beam processing machine, and 20-30 pieces are sent each time, and the wood beam processing machine completes flattening, cutting, Cutting into sections, winnowing and dedusting, and finally get 5mm wide and 70mm long wood bundle strips without skin, pith and impurities, and then send the wood bundle strips into the all-in-one machine, which will be dried by the all-in-one machine to make the water content ≤ 6% , and then enter the glue mixing section. The glue can be urea-formaldehyde glue. The strands are laid flat according to the thickness requirements, and then three sets of flattening rollers corresponding to each of the three layers of vibrating screens are used for initial pressing, and then the three layers of initially pressed slabs are pressed together in the slab combining section composed of 6 sets of rollers. Together, a complete...

Embodiment 2

[0019] One of the five kinds of straw is processed into 5mm wide and 70mm long wooden beam strips, which are dried, glue mixed, paved and billeted by the integrated machine, and then sent to the hot press machine. The glue material can be phenolic glue. The amount of glue is 8% of the net weight of the wood beam strips, and the wood beam strips can be selected from any of the five kinds of straws. The other process conditions are the same as in Example 1, and qualified wood beam boards can also be produced.

Embodiment 3

[0021] After the whole straw is processed into wooden beams, it is sent to the all-in-one machine, which completes drying, glue mixing, and paving. After forming the billet, it is sent to the hot press machine. It is 5% of the net weight of wood beam strips, and other process conditions are the same as embodiment 1, and qualified wood beam boards can be produced equally.

Abstract

The invention discloses a technique for producing a wood bundle board by using straws, and belongs to the field of artificial board production. The wood bundle board is an artificial board formed by processing the straws into elongated small straw sections with width of 5 millimeters and length of 70 millimeters, then applying resin adhesive and thermally pressing the elongated small straw sections. Because the small straw sections with width of 5 millimeters and length of 70 millimeters are convenient for applying the adhesive, pavement and assembly are convenient, and large-scale production is favorable; meanwhile, the elongated straw sections with width of 5 millimeters and length of 70 millimeters can enhance the internal bonding force of a board blank, so that the structure in the board is more scientific and reasonable; the board produced by using the method has high strength and low cost; and the board can be widely applied in the fields of building decoration, furniture manufacture, package, transportation and the like.

Description

Technical field: [0001] The invention discloses a technical method for producing wood-bundle boards by using straws, belonging to the field of wood-based panel production, that is, using crop straws as raw materials instead of wood to produce wood-based panels. [0002] The wood beam board: it is a man-made board made by processing the whole straw into a wood beam strip with a width of 5 mm and a length of 70 mm, which is then dried, glued, paved, formed into blanks, and hot-pressed. Background technique: [0003] With the reduction of wood resources, it is imperative to use crop straw instead of wood to produce wood-based panels, but how to develop a technical method that is high in strength and low in cost and suitable for large-scale industrial production is very important. The straw is pulverized, mixed with glue, and hot-pressed to form it. The plate strength produced by this process method is relatively low. The core technology disclosed in the method for making lamina...
