Description

A kind of human spine-shaped thin strip bamboo board and its manufacturing method

technical field

The invention belongs to the technical field of furniture and interior decoration art materials, and in particular relates to a human spine-shaped thin bamboo strip plate and a manufacturing method thereof.

Background technique

The prior art generally uses wood as the furniture base material. Because the raw material used is wood, and wood resources are very scarce in my country, it greatly affects the development of my country's furniture industry. However, my country is rich in bamboo resources, and the growth cycle of bamboo is short. It takes only 5-8 years for afforestation to succeed once and the time to become a timber is short. The development of new human body spine-shaped thin strips of bamboo can solve the crisis of raw materials for furniture and indoor art, and realize "replacing wood with bamboo", which is not only conducive to the further development of my country's furniture industry, but also improves the utilization value of bamboo and promotes the economic development of remote mountainous areas ; At the same time, it can protect forests and ecological environment, and has good economic, social and ecological benefits.
