Problems solved by technology

The traditional processing method of bamboo boards is: take moso bamboo and break it into bamboo silk or bamboo slices, after drying, dip into the mold, and then press high pressure to solidify the molding materials. Although the existing production technology is relatively mature, the product quality is relatively high. Ideal, but due to the large changes in the process parameters in the production process and the specific methods of pressing and forming are not completely the same, the quality indicators of the bamboo boards cannot meet the best requirements, especially the density uniformity of the boards and the direction of width and thickness The anti-deformation performance needs to be further improved. Some export products are often returned because they cannot meet international standards, and cannot occupy the international market to the maximum extent.
In addition, for the boards used in some special industries, such as: outdoor decorative materials, indoor geothermal flooring, indoor swimming pool floors, etc., the existing bamboo boards cannot fully meet their use requirements

Abstract

It relates to bamboo plate production method. 1) it processes bamboo fiber to thread bamboo sheet, 2) bleach, carbonize and dry after modifying property, 3) soaking the said bamboo sheet in glue agent, dry to the water content 10-12%, taking the bamboo plate of the corresponding weight based on 1.1-1.3g / cm3 intensity to fill into the mold, 5) sending the bamboo sheet to heat compressor with compression force 6-10 MPa for 30-60 minutes, setting the compression temperature 100+-5DEG C for melamine resin adhesive, or 135+-5DEG C for phenol aldehyde resin adhesive, and 6)process the compressed plate. The made bamboo plate is even in intensity, high in static curve strength and hardness, anti wearing and good in stability.

Description

technical field [0001] The invention belongs to the technical field of bamboo board production. Background technique [0002] Bamboo is used as raw material to process and make boards. Because the raw materials are cheap, easy to obtain, low cost, beautiful in appearance, high in strength and good in performance, they are widely used in flooring, furniture and other decorative boards or other industries. In particular, moso bamboo grows fast and is rich in resources. It can be a good substitute for wooden boards, saves wood resources, and is conducive to the protection of the ecological environment. Therefore, it has been paid more and more attention by the country and the industry. The traditional processing method of bamboo boards is: take moso bamboo and break it into bamboo silk or bamboo slices, after drying, dip into the mold, and then press high pressure to solidify the molding materials. Although the existing production technology is relat...
