Problems solved by technology

However, bamboo usually has high density, high strength, and strong elasticity. If all bamboo is used to make oriented strand board, the quality of the product will be too large, the internal bonding strength will be low, and the dimensional stability of the product may be affected. Therefore, this project Mainly discuss the production method of oriented strand board made of bamboo and wood respectively, so as to meet the material standard requirements of container floor

Embodiment 1

[0016] Embodiment 1: Take bamboo and timber as raw material, press thick 15mm, density 0.72g / cm 3 bamboo oriented strand board. Firstly, bamboo shavings are produced from bamboo and wood by chipping machine. The width of bamboo shavings: distributed in the range of 12.5-25mm; the thickness of bamboo shavings: in the range of 1.0-1.2mm; the length of bamboo shavings: in the range of 120-150mm. The width of wood shavings is in the range of 12.5-25mm; the thickness of wood shavings: in the range of 0.4-0.8mm; the length of wood shavings: in the range of 120-150mm. Bamboo shavings and wood shavings are dried (moisture content: 5.2%) and glued (MDI glue: 3.0%); then paved on a three-layer directional paving machine, and the bamboo shavings on the upper and lower surfaces are shaped parallel to the pavement in the length direction The line direction is arranged horizontally, the pavement thickness accounts for 20% of the board thickness respectively, and the wood shavings of the ce...

Embodiment 2

[0017] Embodiment 2: Take bamboo and timber as raw materials, press thick 18mm, density 0.71g / cm 3 bamboo oriented strand board. Firstly, bamboo shavings are produced from bamboo and wood by slicing machine. The width of bamboo shavings: distributed in the range of 12.5-20mm; the thickness of bamboo shavings: in the range of 1.0-1.2mm; the length of bamboo shavings: in the range of 90-120mm. The width of wood shavings is in the range of 12.5-20mm; the thickness of wood shavings: in the range of 0.6-1.0mm; the length of wood shavings: in the range of 90-120mm. Bamboo shavings and wood shavings are dried and sized (moisture content 4.2%) and glued (pF glue 7.2%); then paved on a three-layer directional paving machine, and the bamboo shavings on the upper and lower surfaces are formed parallel to the pavement in the length direction The line direction is arranged horizontally, the pavement thickness accounts for 25% of the board thickness respectively, and the wood shavings of t...

Embodiment 3

[0018] Embodiment 3: Take bamboo and wood as raw materials, press thick 28mm, density 0.70g / cm 3 bamboo oriented strand board. Firstly, bamboo shavings are produced from bamboo and wood by slicing machine. The width of bamboo shavings: distributed in the range of 12.5-20mm; the thickness of bamboo shavings: in the range of 1.0-1.2mm; the length of bamboo shavings: in the range of 90-120mm. The width of wood shavings is in the range of 12.5-20mm; the thickness of wood shavings: in the range of 0.6-1.0mm; the length of wood shavings: in the range of 90-120mm. Bamboo shavings and wood shavings are dried (moisture content: 5.6%) and glued (MDI glue: 3.8%); then paved on a three-layer directional paving machine, and the bamboo shavings on the upper and lower surfaces are formed parallel to the pavement in the length direction The line direction is arranged horizontally, and the pavement thickness accounts for 30% of the board thickness respectively, while the wood shavings of the ...

Abstract

The invention provides a manufacturing method for a bamboo and wood oriented strand board for bottom plates of containers. The method includes the following steps that firstly, bamboo and wood serve as raw materials; secondly, the bamboo and the wood are used for manufacturing bamboo shavings through a chipping machine; thirdly, the bamboo shavings and wood shavings are dried; fourthly, 6-10% of pF glue is applied, and 2-7% of MDI glue is applied; fifthly, oriented laying is performed on a three-layer oriented laying machine; sixthly, the slab of a three-layer oriented structure is manufactured through laying; and seventhly, a rough board which is hot-pressed is cooled in a plate turning cooling device. The method has the beneficial effects that the bamboo and the wood are laid in a layered and oriented manner to manufacture the bamboo and wood oriented strand board which is a good structural material and an outdoor material, and the bamboo and wood oriented strand board is high in strength, good in size stability, high in waterproof performance, environment-friendly and good in machining performance. By using the manufacturing method, the technology is stable in the production process, and the manufactured board meets the requirement of the standard (GB/T19536-2004) of plywood for the bottom plates of the containers in China.

Description

technical field [0001] The present invention relates to taking bamboo and wood as raw materials, and mechanically chipping the bamboo and wood respectively to produce large pieces of flat, narrow and long shavings, bamboo shavings and wood shavings, which are then dried, applied with adhesive, and layered and oriented paving of slabs It is a kind of structural board manufactured by processing processes such as hot pressing and hot pressing, and is used as a bamboo-wood oriented strand board method for container bottom boards. It belongs to the technical field of wood-based panel manufacturing. Background technique [0002] Container refers to a large-scale loading container with certain strength, rigidity and specifications specially used for turnover. At present, my country is the largest manufacturer of containers in the world, and has created three world firsts in this production field. As the global economy and trade continue to recover, the demand in the container tra...
