Bamboo board makes life better
As the reducing of global timber resources, bamboo has the characteristics of simple reproduction, fast growth, early maturity, and high output value. It also has a successful afforestation and can be selectively cut year after year and used continuously without destroying the ecological environment. Bamboo board has straight texture, elegant color and tough raw material. It has many benefits compared with hardwood. It is an aspirational material for the production of furniture, floors and various components. Pure bamboo furniture is not only a practical commodity, but also has an appropriate ornamental value, which makes people have the comfort of returning to nature, and can also feel the smell of Chinese traditional culture. Nowadays, some manufacturers combine the characteristics of our country's culture to announce the new style of bamboo furniture, which has opened up a new world to the international market.
Quality is the core of the product. Due to the different production methods and technological standards of various enterprises, some problems have been exposed in the production of bamboo panel furniture. What is outstanding is that bamboo panel furniture is prone to insects, frogs, mildew, water absorption, dry cracks, and degumming deformation. How to deal with these problems is the concern of enterprises. Based on years of research and production practice, here are some quality issues in the production of bamboo furniture.
1. Characteristics of bamboo board (bamboo laminated timber)
1.1 Characteristics of bamboo board
Bamboo board has a small diameter, a hollow wall and a large sharpness, and its structural composition is very different from that of wood. The strength and density of bamboo are higher than that of ordinary wood, and the strength of bamboo board products is greater than that of ordinary wood products. When used as structural materials, bamboo products are smaller than wood products. The bamboo board has straight texture, smooth texture, simple color, easy to bleach, dye and carbonize, and can be comparable to some broad-leaved wood. Bamboo panels and bamboo floors can replace precious broad-shaped leaves, and have a broad application prospects in furniture, ornaments and interior decoration.
1.2 Excellent mechanics and physical and chemical functions
As a new type of furniture material, bamboo board adheres to the characteristics of good physical and mechanical functions of bamboo material and low shortening rate. It has the original characteristics of large format, small deformation, stable standard, high strength, good rigidity, and abrasion resistance. It can be processed by sawing, planing, cutting, drilling, sanding, assembly and surface decoration. Because the bamboo laminated timber undergoes certain hydrothermal treatment when it is produced, the product has good sealing properties and can effectively avoid insects, frogs and mildew. The modified UF resin glue is selected for the laminated bamboo, which is lower than the free nail of the artificial board and is environmentally friendly.
The slicing of bamboo veneer is similar to veneer slicing. It is a bamboo veneer that is sliced from the bamboo glulam using a slicer, and the thickness is generally 0.6mm. After hot pressing, sticking the bamboo skin to the wood-based panel can be used as a new-textured furniture wood-based panel. Generally, it can be used as laminates and panels for furniture.
The surface of bamboo laminated lumber has natural fine and straight textures, and the bamboo joints are scattered. The edge of the board has the natural texture of bamboo board. In addition, its structure is different, and the decorative effect is also different. This aspect is compared with the wood-based panel used in furniture. The big difference is that the wood-based panels used in furniture not only require finishing, but also require edging decoration, while the edges of the bamboo-glulam panels can only be milled. Compared with general solid wood, the mechanical strength of laminated bamboo is higher, and the shrinkage coefficient is smaller.
1.1 Characteristics of laminated bamboo furniture
1.1.1 Simple, light and beautiful shape
Compared with wooden furniture, because bamboo has stronger physical and mechanical functions, under equal load-bearing mechanical strength, new-style bamboo laminated furniture components can meet the strength requirements with a smaller standard. The overall shape of the furniture is lighter, and it can better reflect the rigidity and strength of bamboo. New-style bamboo laminated timber furniture is exquisite and concise in shape and straightforward and smooth in lines; it can complete the modular combination and extension of furniture; the overall planning advocates the natural, simple and environmentally friendly characteristics of furniture; seeks the diversification of furniture functions to the greatest limit Satisfy people's comfort needs; through the use of various materials and rich color changes, it has a variety of styles to meet the needs of customers at different levels; the new-style bamboo laminated furniture planning can be integrated with architectural planning and interior planning And it has the function of carrying space integration.
1.1.2 The process is simple, easy to complete the industrialization of
new-style bamboo laminated furniture, break the traditional technology, and complete the industrial production. Because the raw materials of laminated bamboo are relatively uniform and easy to process, when using electric tools like saws, the saws can move smoothly and have less wear on the tools. For this reason, the use of bamboo laminated timber to develop removable furniture not only has many benefits from the production of modern large-scale industries in terms of planning, production, storage, transportation, and sales of equipment, but also from the perspective of ecological planning, it also contributes to environmental protection. It has an important meaning and has the benefits that traditional frame furniture is difficult to compare.
1.1.3 The material is environmentally friendly and has the characteristics of "green products".
The production of bamboo board laminated lumber mainly selects UF resin glue with low free formaldehyde content or non-toxic special glue; compared with the glue used for traditional wood-based panels, bamboo board laminated lumber is produced Pay more attention to environmental protection when using glue. Improve the health and environmental protection of bamboo products: The free formaldehyde of synthetic resin used in the production of bamboo products is required to meet the requirements of international standards. The amount of formaldehyde released from laminated bamboo panels.
Comparison of free formaldehyde emission between bamboo laminated lumber and wood-based man-made panels
Material free formaldehyde emission (mg/L)
Bamboo laminated lumber (1) 0.8 reached E1 standard
Bamboo laminated lumber (2) 0.7 reached E1 standard
Blockboard 3.2 reached E2 standard
Plywood 3.6 reaches E2 standard
1), clear and beautiful bamboo knots The surface of bamboo laminated lumber has natural fine and straight textures, and the bamboo knots are scattered and very beautiful.

2), good physical function
Bamboo board as a new type of furniture base material adheres to the characteristics of bamboo material physical, mechanical function, and low shortening rate. As the bamboo laminated lumber passes through a certain water and heat area when it is produced, the product has good sealing properties, which can effectively avoid insects and mildew.
Compared with ordinary solid wood, the mechanical strength of bamboo board is larger, and the shrinkage coefficient is smaller.
