Abstract

A plyboard is made up of multiple wood plys and multiple bamboo plys through alternative laminating and hot pressing.

Description

technical field [0001] The invention relates to a plywood, in particular to a bamboo-wood plywood. Background technique [0002] The bamboo and wood industry started in China in the 1990s. Substituting bamboo for wood and continuously expanding the application field of bamboo is an effective technical measure to alleviate the poverty of forest resources and improve the ecological environment. my country's bamboo forests are rich and fast-growing for four years. It is an effective green resource to replace rainforest wood. [0003] Thus, there have been a lot of technologies and corresponding patent applications related to bamboo flooring. For example, the utility model patent CN2661631Y filed by the applicant of the present invention on July 30, 2003 discloses a container bamboo-wood plywood comprising at least two layers of wood boards and at least one layer of bamboo boards. Set in the inner layer, the bamboo single layer is glued directly to the bamboo single layer, and ...
