Abstract

The invention discloses a production method of ultra-low water absorption bamboo wood fiber decorative plate. (1) fermentation broth is prepared, specifically, a bacillus subtilis strain xp is suspended in an LB liquid medium, and an inoculating loop is used for picking up a bacterial solution and culturing on a slant at 20-40 DEG C for 2-14 h; bacterium obtained are aseptically picked up a singlecolony by the inoculation loop and the single colony is inoculated into an LB liquid medium containing 0.1 g / L malic acid and cultured in a shaking table at 30-38 DEG C until an OD600 value is 2.0, and the fermentation broth is obtained; (2) raw materials prepared, specifically, the raw materials are all dried to a moisture content of 8% and comprise, by weight, 50-55 parts of bamboo fibers and 5-8 parts of pine wood shavings, and the raw materials are uniformly mixed; evenly mixed raw material plant fibers are uniformly sprayed with the fermentation broth and turned, and the mixture is fermented at 32-38 DEG C for 8-10h; the amount of spray is that the fermentation broth is 0.001 time the weight of the plant fibers; after fermentation, drying is carried out at the temperature of 60 DEG Cto a moisture content of 8%, and the raw material plant fibers are pulverized into powder for use; (3) molding is performed.

Description

technical field [0001] The invention relates to an ultra-low water absorption bamboo fiber decorative board, which belongs to the field of decorative boards. Background technique [0002] Natural Vegetable Fibers (NVF) are the most abundant natural polymer materials in nature, such as wood, bamboo, straw, wheat orange, rice bran, peanut shell, bagasse, coconut shell, flax, ramie, etc. The total amount of growing cellulose (existing in the form of natural plant fibers) is as many as 100 billion tons, which far exceeds the total existing oil reserves on the earth. In addition, there are a large number of natural fiber resources such as agricultural processing waste, especially in some tropical regions. The research on renewable resources has been listed as one of the 24 frontier fields in the world, and countries have invested a lot of money in research and development. According to the U.S. Department of Energy (DOE) "Plant and Food-Based Renewable Resources Technology Roadm...
