Description
Technical Field
The invention relates to a production device and a production method of building materials, in particular to a production device and a production method of bamboo building materials, and especially relates to a gluing method, a gluing device and application of arc original state recombined bamboo plates and bamboo chips.
Background
The forest resources of China are lack, the forest coverage rate and the average forest possession are low, and the large-diameter useful log is very lack. The annual consumption of wood in China is increased from 1.8 hundred million cubic meters to 6.1 hundred million cubic meters in 2016, and besides the domestic autogenous part of wood, the dependence on imported wood is over 50% at present, and the annual growth rate is 10%. With the enhancement of environmental protection awareness of various countries, many countries have begun to limit log export, and the wood types of the export are limited to 240 more, so that in order to ensure the rigidity requirement of the market on the wood, construction of a wood strategic reserve base should be enhanced, wood substitution materials should be searched, and the wood utilization rate should be improved. The bamboo rattan resources in China are rich, more than 30 kinds of bamboos belong to 530 kinds of bamboos, and according to the eighth forest resource investigation result in China, the existing bamboo forest area is 601 ten thousand hectares, wherein the areas of natural bamboo forests in Fujian, jiangxi, zhejiang, hunan and other provinces in China are about 75%, and the areas of bamboo forests in Zhejiang, guangdong, sichuan, guangxi, fujian, anhui and other provinces in China are 77%. Bamboo plants have unique biological, mechanical and ecological characteristics, and simultaneously have good economic, ecological and social benefits, and are considered as the plants which have the highest hope and potential to replace wood resources in the future. The bamboo industry is a great sun-facing industry, and practice proves that the bamboo is used for replacing wood and the bamboo is used for winning wood effectively. In recent years, the bamboo industry has achieved significant achievements in promoting green growth and building modern forestry. The application space of bamboo products in China is continuously developed and expanded, and the expansion of the fields of modern bamboo building materials, bamboo fibers, composite materials, energy and the like is accelerated on the basis of traditional bamboo tools, bamboo gardens and bamboo products. The bamboo industry relates to more than 10 fields of building materials, decoration, building, home furnishings and the like, bamboo products form more than 100 series of thousands of varieties, and the importance of bamboo is increasingly prominent.
However, these bamboo products have low bamboo utilization or high glue content due to impregnation, increase cost of the products and reduce environmental protection performance, and are not high in economical and environmental protection performance, and the application range thereof is limited. Along with the increasing popularization of ecological civilization concepts and the development of green environment-friendly materials, high utilization rate, low glue content and original ecological bamboo products are gradually agreed and promoted, how to develop the original bamboo materials, how to break through and innovate processing technology, equipment, evaluation methods and the like become the problems to be solved urgently in the development of innovative bamboo industry.
The original bamboo board is made up by cutting bamboo tube into several equal width bamboo slices along radial direction, removing bamboo joints and sections, planing off green bamboo yellow, making into equal width equal thickness bamboo slices, mechanically coating glue and heating (cooling) to obtain the invented board. The wider the bamboo tube is cut, the larger the cutting amount is, the lower the bamboo utilization rate is, so the widest the bamboo tube is generally 24 mm, and the bamboo utilization rate is only 15% -35%.
The bamboo arc original state recombination technology is a new material researched by Beijing forestry machinery research institute of Hunan forestry department and national forestry institute, wood industry research institute of China forestry department, which is to divide whole bamboo into arc bamboo strips with specification, to remove knots, to remove green and yellow, to process into arc bamboo strips with the same outer arc radius and inner arc radius as arc bamboo units, to discharge the arc bamboo units with certain roughness in parallel with the same arc direction, to process into boards through lateral and up-down compression molding, to process the surfaces of several boards into flat, assemble, glue and compression molding to form recombined materials with different thicknesses according to the requirement. Also called arc original state recombined bamboo boards.
The arc-shaped raw bamboo chip recombined plate is manufactured by raw arc milling, namely milling to remove a thin layer of surficial bamboo green (the surface protruding bamboo joints and the bamboo wax parts are removed) and a thin layer of surficial bamboo yellow (the inner siliceous bamboo yellow parts are removed), so that the surficial bamboo green bamboo yellow parts which do not affect the bonding quality are reserved, the utilization rate of the bamboo is high and reaches 60% -80%, the maximum chord height of the bamboo chip can reach 60 mm, the chord height of the bamboo chip is generally processed for 40 mm, the thickness of the processed bamboo plate is large, the utilization rate of the bamboo is high, most of the surficial bamboo green is reserved, the density of the surficial bamboo green is high, the toughness is good, the tensile strength is strong, and the mechanical strength of the manufactured plate is larger, and the recombined plate is suitable for furniture, structural materials and other materials.
One important process in the manufacture of arc original state recombined bamboo board is bamboo chip gluing. The method adopted is dip coating and spray coating. The dip-coating is to put the bamboo chips into glue solution, take out after the whole bamboo chip is dipped, and then make up the blank to make the board, the method glue the bamboo chip in all directions (the two side surfaces can not be glued), the glue dipping amount is large, the glue solution waste is large, the cost is high, and the formaldehyde content in the corresponding board is also high; the glue is wasted greatly, the glue is not likely to be sprayed on the bamboo chips when the glue is sprayed, and the glue is sprayed on the peripheral positions of the corresponding bamboo chips, so the glue is wasted greatly, and the working environment is poor, if the glue contains toxic and harmful substances, the glue is very unfavorable for the health of production workers; the existing gluing machine is not suitable for gluing arc-shaped bamboo chips. After the bamboo chips are made, the two methods are to glue the bamboo chips, and the bamboo chips are processed into the plate through three-dimensional hot (cold) pressing.
