Bamboo filament fibre board and bamboo filament, method for making bamboo filament fibre board

Abstract

The invention relates to a bamboo fiber plate, which is made from bamboo fiber at 0.1-0.3mm wide while the length / diameter ratio is 200:1-500:1, to be alternated. Wherein, the bamboo fiber is adhered by melamine- formaldehyde-aquacare resin; it uses explosion method to product bamboo fiber, that cutting bamboo into sheets wide 2-3cm and long 5-7cm; emerging it in 0.5-1% sodium sulfite solution for 10-15h, adding water at 5-10% of total amount, increasing pressure to 101-8kg / cm<2 in 10-15mins, increasing temperature to 106-120Deg. C, keeping said temperature for 18-25min, discharging pressure and exploding into bamboo wires. And the method for producing bamboo fiber plate comprises that mixing the melamine- formaldehyde-aquacare resin with solidifier amchlor at 100:0.5-100:1.0, to be sprayed on bamboo wires; pressurizing it at 4.5-5.5 kg / cm<2, then keeping pressure 3.9N / mm<2 at 160-165Deg. C for 5-10min; and keeping pressure at 1.6N / mm< for 25-30mins, cooling. The invention has low energy consumption and wide application.

Description

[0001] Technical field: The present invention relates to a kind of bamboo artificial board and its manufacturing method, especially the manufacturing method of bamboo silk fiberboard and bamboo silk, bamboo silk fiberboard. Background technique: [0002] China is the central production area of ​​bamboo distribution in the world. The bamboo forest area accounts for more than 1 / 5 of the world's total bamboo forest area, with an annual output of more than 5 million tons of bamboo. At the same time, my country is a country with relatively poor forest resources. No matter from the current situation or in the medium and long term, the contradiction between supply and demand of timber is a relatively prominent problem. As a raw material resource, timber has always been regarded as a short-term substance. With the implementation of the strategy of "replacing wood with bamboo" and the continuous injection of scientific and technological vitality, bamboo forests can be applied in a wider...
