Problems solved by technology

At present, the shortcomings of bamboo plywood are becoming more and more obvious. For example, the overall density of the current bamboo plywood is small (only 0.7-0.9g / cm 2 ), the texture is loose, very easy to deform and crack, so the scope of use is narrow
Moreover, because the moisture content of the raw materials before and after the glue is relatively high, the pressed bamboo plywood is very easy to foam and delaminate.

Embodiment Construction

[0023] Specific production examples:

[0024] 1. The moso bamboo slices bought in the market are first selected for carbonization.

[0025] 2. The selected moso bamboo sheets are rolled into flake-like strips (about 2×20×1950mm in size) that are broken in the fiber direction.

[0026] 3. Put the bamboo slices into the carbonization furnace for surface treatment such as carbonization.

[0027] 4. Put the bamboo slices into the drying room to dry to make the moisture content below 13%.

[0028] 5. Put the bamboo slices in the phenolic resin adhesive for dipping. After dipping for 6-10 minutes, take out the bamboo slices, drain them, and then put them in a chain drying room at 50-70°C to dry to make the moisture content Reach 10-12%.

[0029] 6. The density of the finished bamboo board is 1.1-1.3g / cm 3 , the thickness is 80mm to calculate, weigh a proper amount of moso bamboo flake strips, arrange the flake strips vertically and orderly and put them into the multi-layer hot p...

Abstract

The invention discloses a high-density phyllostachys pubessens fiberboard. The phyllostachys pubessens fiberboard is a bamboo plywood produced by using the concept of arranging phyllostachys pubessens fiber vertically and laterally for recombination. Phyllostachys pubessens fiber belongs to coarse fiber and has better tensile strength, and the high-density phyllostachys pubessens fiberboard produced by using the recombination of the phyllostachys pubessens has the following main characteristics: 1, the bamboo plywood is the recombination of phyllostachys pubessens fiber instead of the simple recombination of bamboo chips; and 2, the phyllostachys pubessens fiber material is formed by heavy lateral and vertical pressure simultaneously, and the density and the texture are both more uniform, thereby greatly prolonging the service life of the bamboo plywood.

Description

technical field [0001] The invention belongs to the technical field of production of bamboo plywood. Background technique [0002] With the influx of bamboo plywood into the market, it is favored by more and more users. At present, the shortcomings of bamboo plywood are becoming more and more obvious. For example, the overall density of the current bamboo plywood is small (only 0.7-0.9g / cm 2 ), the texture is loose, and it is very easy to deform and crack, so the scope of use is narrow. And because the moisture content of the raw materials before and after the glue is relatively high, the pressed bamboo plywood is very easy to foam and delaminate. Contents of the invention [0003] The present invention is a bamboo plywood produced by utilizing the concept of closely arranging up, down, left, and right sides of moso bamboo fibers and recombining them. Moso bamboo fiber is a thick fiber with good tensile strength. The main characteristics of the high-density moso bamboo ...
