Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a bamboo piece, and in particular, a joined body covered with a hydraulic plywood machine is formed into a required size in a process of vertically combining and adhering bamboo pieces, and further, It relates to a method in which details are corrected to be flat, polished, and further subjected to mildewproofing and varnish coating to obtain required hardness. Bamboo products produced by the method of the present invention can withstand relatively large loads and can replace traditional wood products,
The combination of chemicals and bamboo fiber enhances the reinforcement of the bamboo pieces themselves, using relatively few materials, and the multiple processing to control their dimensions to reduce the thickness and hence the operation when made into a product. It is easy to use, has a long service life, and is highly effective.

2. Description of the Related Art Conventional wooden blinds have been the main product for furniture-type blinds in the past because they are easy to obtain and cost low. However, recently, due to the excessive deforestation of the forest, the total forest area of the earth is decreasing, the environment is being destroyed, and it takes time to grow trees (more than 10 years are required for lumber). Is no longer easy to obtain. Moreover, the lack of pressure resistance of the wood fiber structure makes it impossible to reduce the thickness of the blade of the blind in order to withstand its gravity in use, which makes the blind operation unsuccessful, which is It directly affected the lifespan. In addition, the blinds using PVC or aluminum blades are light and convenient to manufacture, but the pollution caused by their manufacturing and disposal is unmatched by products using natural resources, and meets the requirements of environmental protection. There wasn't.

On the other hand, a bamboo blind is difficult to control because its manufacturing process is complicated, but since the texture of the bamboo itself is fine and the pressure resistance is high, the blade thickness can be reduced, and therefore the product is lightly operated. It is easy to grow, the bamboo grows fast (it grows into wood in two years), it has relatively little impact on the environment, it is economical and practical, and it has a good appearance. Most suitable to replace wooden blinds.
