Abstract

The invention discloses a composite fibreboard of psammophyte bush. A manual fast-growing forest timber is mixed in the psammophyte bush to prepare mixed fibre by a mixed jordaning method; and the mixed fibre reduces the bark content of the psammophyte bush and improves the fibre quality of the psammophyte bush, thereby improving the quality of the fibreboard. The invention also provides a method for manufacturing the composite fibreboard of the psammophyte bush; the method comprises the main steps: (1) material preparation; (2) hot grinding; (3) adhesive application and drying; (4) pavement; (5) hot pressing; (6) edge trimming, and other working procedures; in the material preparation section, wooden chips of the psammophyte bush with length of more than 10 cm are controlled within 5 percent; or the psammophyte bush is cut into small sections of crabsticks with the length of between 1.5 and 5.0 cm; and the wood chips or the crabsticks and the wood chips of the fast-growing forest timber are mixed to solve the problems that uncut strips of the psammophyte bush wind a cutter wheel of a drum-type chipper and block a tub wheel and a screen, and the like.

Description

technical field [0001] The present invention relates to a sand shrub composite fiber board made of artificial fast-growing wood and sand shrubs as main raw materials, especially a sand shrub composite fiber board prepared from three mixed fibers of salix salix, amorpha amorpha and poplar; the present invention also A method for manufacturing the fiberboard is provided. Background technique [0002] Psammoshrub is a perennial shrub plant widely grown in arid and semi-arid regions in my country. It has the characteristics of cold resistance, drought resistance, high temperature resistance, sand burial resistance, strong adaptability, and fast growth. The main tree species are salix, caragana, red willow, black willow, poplar, flower stick, wolfberry, amorpha and so on. According to the biological characteristics of these sand shrubs, it is necessary to rejuvenate once every 3 to 5 years, so that they can grow normally, otherwise, they may stop growing or even die. At present...
