Description
Technical Field
The utility model relates to a house technical field especially relates to an ecological bamboo core of high strength based on bamboo wood is compound.
Background
With the economic development and the population growth, the demand of human beings on wood and wood products is continuously increased, but the contradiction between supply and demand of wood is increasingly highlighted due to the reduction of forest resources and the implementation of forest protection policies. Bamboo is the preferred raw material for supplementing wood due to its short growth cycle and good wood properties. China has abundant bamboo resources, and the bamboo resources are vigorously developed and utilized, so that the method is one of effective ways for relieving the supply-demand contradiction of wood. The bamboo wood has high strength, high toughness and good wear resistance, and has wide application prospect in the field of household plates. However, the bamboo products have complicated production process and low automation level, so the processing cost is high and the wide popularization is difficult. The bamboo and wood composite technology can keep respective characteristics of bamboo and wood, not only reduces production cost, but also can ensure dual benefits of product internal and appearance quality, and is one of important technologies for future development of household boards.
The traditional household board generally takes a plurality of layers of solid wood boards, solid wood particle boards and density fiber boards as main materials. The multilayer solid wood board is made by using multilayer plywood arranged in a criss-cross mode as a base material and using solid wood veneers as a decorative surface through the working procedures of cold pressing, hot pressing, sanding and the like. The multilayer solid wood board has the characteristics of high strength, small deformation and good nail-holding power, but the utilization rate of raw materials is low. The solid wood particle board is made by using small diameter wood and branch wood as raw materials and wood chips thereof through high-pressure gluing. Because the wooden particles in the board are larger and distributed in a crossed and staggered manner, the solid wood particle board has better deformation resistance and better nail-holding power. The density fiberboard is prepared by taking wood or other plant fibers as raw materials, preparing the fibers, adding synthetic resin, and pressing under the conditions of high temperature and high pressure. The density fiberboard has small internal units and high density, is easy to be cut into arcs, has the surface capable of being baked with paint, is suitable for being made into European and rural cabinet doors, but has poor nail holding power and is easy to expand when being damped. Compared with a multilayer solid wood board, the solid wood particle board and the density fiberboard have high utilization rate of raw materials, but have weaker physical and mechanical properties. The plates have various characteristics, but the properties of the household products made of the plates are limited due to the characteristics of the raw materials.
With the development of social economy, the demand of household plates is getting bigger and bigger, and how to produce the household plates with high strength, high density, good bending resistance, high utilization rate of raw materials and low cost is a problem to be solved urgently in this neighborhood.
