Problems solved by technology

[0002] With the reduction of wood resources, it is imperative to use crop straw husks to produce man-made panels, but how to develop panels with low cost and high strength is very important; Split the sunflower stalk, then remove the pulp and skin, and add some filling materials to the sunflower stalk before molding, such as bamboo skin, steel mesh, etc. Although the board can replace the wooden board, the process is cumbersome and the production cost is high. Too high; a method of making boards with straws (CN1383966A) All straws used must be crushed to remove the pith core, braided into sheets with wire ropes, and then three to nine sheets are stacked together, and the direction of the adjacent sheets is Cross laying, then send into hot press, this method process is complicated and complicated, is unfavorable for large-scale industrial production; Reed fiber composite board production method, (CN96112163) is cement and gypsum with cement and gypsum, and the product itself is too heavy and has limited uses

Embodiment 1

[0017] First, crush the peanut shells into a flat sheet, break the sunflower stalks from the middle, remove the skin core, then dry or air-dry to make the water content <6%, and then enter the sizing process; the peanut shells Pour it into the glue mixing machine for sizing, spray the sunflower stalks with a glue gun, and spray the wood skin with a glue gun or brush it by hand. The glue is made of urea-formaldehyde resin glue with a solid content of 60%. The amount of sizing is 10% of the weight ratio of raw materials, and then it enters the paving process; firstly, the wooden skin after sizing is laid on the aluminum formwork, and then the peanut shells are laid, each layer is 20mm thick, and then the sunflower stalks are pressed on the same Lay the peanut shells vertically in parallel, then lay the second layer of peanut shells, the layer thickness is also 20mm, then lay the second layer of sunflower stalks horizontally in the same direction, and then lay the third layer of p...

Embodiment 2

[0019] Peanut shells are rolled, sunflower stalks are dried or air-dried after removing the skin core, and the moisture content is less than 6%. After the peanut shells and sunflower stalk wood skins are glued, they enter the paving process; first, the wood skins are laid on the aluminum formwork Then put the peanut shells on the wooden surface with a layer thickness of 15mm, then lay the sunflower stalks in the same direction, parallel and vertically lay them on the peanut shells, and then lay the second layer of peanut shells, the layer thickness is also 15mm, Then lay the sunflower stalks on the peanut shells in parallel and horizontally in the same direction, that is, one layer of peanut shells and one layer of sunflower stalks to form a criss-cross multi-layer structure. Repeated laying of 6 layers can press out 2440mm×1220mm×10mm Length×width×thick board, other process conditions are the same as embodiment 1, can produce qualified man-made board likewise.

Abstract

A technical method for manufacturing artificial boards with peanut shells and sunflower stalks by pressing belongs to the non-timber artificial board manufacturing industry, and is a technical method for manufacturing artificial boards with agricultural waste such as stalks and shells serving as raw materials by pressing. All indexes of the artificial boards manufactured by the method reach the national standards of flakeboards and shaving boards, so that the artificial boards can be widely applied to packaging and home decoration industries, and are lower in manufacturing cost, free of environmental pollution and suitable for large-scale industrial production.

Description

Technical field: [0001] The invention discloses a technical method for pressing wood-based panels with peanut shells and sunflower stalks, which belongs to the non-wood wood-based panel production industry, and is a technical method for pressing wood-based panels with crop straw shells. Background technique: [0002] With the reduction of wood resources, it is imperative to use crop straw husks to produce man-made panels, but how to develop panels with low cost and high strength is very important; Split the sunflower stalk, then remove the pulp and skin, and add some filling materials to the sunflower stalk before molding, such as bamboo skin, steel mesh, etc. Although the board can replace the wooden board, the process is cumbersome and the production cost is high. Too high; a method of making boards with straws (CN1383966A) All straws used must be crushed to remove the pith core, braided into sheets with wire ropes, and then three to nine sheets are stacked together, and t...
