Problems solved by technology

Strong board (CN1261717) first mix magnesium oxide, magnesium chloride and magnesium silicate for 10-40 minutes, weave bamboo, reed stalks, palm leaves and other plant stems into a mesh, use glass fiber cloth as the middle layer skeleton, and flatten it Natural molding, its products are naturally cured molding, the strength is limited, the product uses a lot of glass fiber, there are also some problems in environmental protection

Embodiment 1

[0016] Firstly, the raw materials should be dehydrated (natural drying and artificial drying) to make the water content <5%, and then the tobacco stalks should be removed and cut into various lengths of 400mm-1500mm. The stalk sections are rolled into sheets with a width of 35mm-65mm, and then the outer skin and pith are removed on special equipment, and then the glue is applied on the gluing machine. 8%-11% of the net weight, the surface layer material is made of 120 grams of corrugated paper or 0.3mm thick wood veneer as the board veneer, first cut the fabric into 2500mm×1300 length×width, then brush glue or spray glue or roll glue, and then Lay the glued fabric on the template, then lay the formwork, and then lay the glued stalks on the surface layer in the same direction and parallel arrangement end to end longitudinally, and then still in the same direction and parallel arrangement end to end in the horizontal direction Lay the second layer of glue-coated stalks in a cris...

Embodiment 2

[0018] The raw materials are dried or air-dried, and the moisture content is less than 5%, so as to ensure that the board does not foam. First, the tobacco stalks are slightly removed, cut into various lengths of 400mm-1500mm, and then processed into 5mm-15mm on special equipment. A variety of stalks of different widths are removed from the outer skin and pith. The stalks processed by this method do not need to be rolled by a pair of rollers, but are directly glued on a roller rubber machine, or sprayed with a glue sprayer. Then 120 grams of corrugated paper or 0.3mm thick wood veneer is cut and glued and laid on the template, then the mold frame is laid, and then the billet is laid in the mold frame. The first layer is arranged end to end in parallel in the longitudinal direction. The glued stalks with different lengths and widths of 5mm-15mm are laid in the mold frame, and the second layer is laid horizontally, which is also arranged end to end in parallel in the same directi...

Embodiment 3

[0020] The surface veneer is 0.2mm thick wood veneer, and the back layer veneer is 90 grams of gypsum board paper to make two layers of veneer on the surface and back of the board. First, lay the cut and glued 0.2mm thick wood veneer on the template, and then lay the mold frame , and then cut into 400mm-1500mm stalk sections, rolled into 35mm-65mm stalk pieces, and then arranged in parallel in the same direction after being glued, connected end to end, criss-cross, and laid repeatedly Lay 7 layers in the form of blank assembly, and then spread 90 grams of gypsum board paper coated with glue on it, then take out the mold frame and lay the template, transfer it to the press, press 7 sheets each time, and use urea-formaldehyde resin glue as the glue. The press is an ordinary wood-based panel press. The pressure is 900 tons, the temperature is 180 degrees, and the pressing time is 12 minutes. Other process conditions are the same as in Example 1, and a qualified plate of 2440mm×12...

Abstract

The invention relates to a filmmaking and assembly method and a pressing process of a tobacco stalk laminated plate, which belong to the production industry of non-wood plant stalk plates, in particular to a filmmaking and assembly method and a pressing process of the tobacco stalk laminated plate, which are used for producing a man-made plate by using tobacco stalks as raw materials to replace wood. Aiming at various defects existing in the production process and the technical formulation of the non-wood plant stalk man-made plates, the invention designs a tobacco stalk filmmaking method and an assembly paving method as well as a pressing process. The invention can effectively improve the plate strength, simplifies the production procedure, and lowers the manufacture cost; and the specific procedure can be detailed in the description.

Description

Technical field: [0001] The method and pressing process of the present invention relate to the manufacturing industry of non-timber plant straw boards, that is, a method of making billets and a pressing process for producing artificial boards by using tobacco stalks instead of wood. Background technique: [0002] With the decreasing forest resources, the industrial utilization of non-timber plant straw resources has been paid more and more attention, and the technology of using crop straws to make boards has been introduced continuously. But all there are many defectives as if, straw composite plate and manufacture method thereof (CN1294094) it is wherein a kind of main material such as rice straw, rice husk, stalk, with light burnt powder, improver, through stirring injection molding, add glass fiber, Drying and demoulding to produce boards. Although the boards produced by this process can replace wood boards, due to the use of a large amount of chemical raw materials and g...
