Problems solved by technology

The thickness of wood chips is required to be between 0.50 mm and 0.80 mm, and waste veneers larger than 1.00 mm are not used. At the same time, due to the overlapping and staggering of wood chips during the paving process, the size of the shavings is different, and the level and uniformity cannot be achieved, resulting in an increase in the internal void ratio of the board. A certain density gradient is formed, and the thickness stability of the produced OSB is poor

Embodiment Construction

[0011] The method for producing oriented strand board by utilizing eucalyptus wood waste veneer of the present invention will be further described in conjunction with the examples below.

[0012] The present embodiment provides a kind of oriented strand board production method, as figure 1 The following steps are shown:

[0013] Length slicing: the eucalyptus waste veneer strips with a thickness of 1.50-2.80 mm are transported to a veneer longitudinal shear for length slicing, and the broken veneer strips are longitudinally cut into slats with a length of 50.00-200.00 mm;

[0014] Width slicing: The veneer strips after length slicing are transported to the veneer transverse shearing machine for width slicing, and the veneer strips are cut transversely into shavings with a width of 10.00-80.00 mm;

[0015] Drying: transport the shavings in the wet silo to the dryer for drying, so that the moisture content of the shavings is 3.00%-8.00%;

[0016] Screening: The dried shavings ...

Abstract

The invention relates to a method for producing an oriented strand board by using a eucalyptus waste single board. The method comprises the following steps: cutting, humidifying and drying the eucalyptus waste single board serving as a wooden sheet of a basic material, putting the eucalyptus waste single board to be in contact with an MDI formaldehyde-free and insoluble hot-setting adhesive, and performing such processes as oriented spreading and continuous hot press molding. According to the method, the oriented strand board processed by the eucalyptus waste single board with the thickness of 1.50-2.80 mm and the MDI formaldehyde-free and insoluble hot-setting adhesive which serve as raw materials is firm, durable and free of formaldehyde, and is lighter in weight and higher in flatness than furniture made of a moderate-density fiber board.

Description

technical field [0001] The present invention relates to a new method for producing oriented strand board (OSB, oriented strand board). Background technique [0002] OSB is mainly used for structural panels and stressed components, and is a good material for building structures, interior decoration and furniture manufacturing. [0003] In the existing OSB production process, the main equipment is imported, the capital investment is huge, and the technical difficulty is high. mm-0.60mm) after drying, sizing, directional paving and thermoforming. The thickness of wood chips is required to be between 0.50 mm and 0.80 mm, and waste veneers larger than 1.00 mm are not used. At the same time, due to the overlapping and staggering of wood chips during the paving process, the size of the shavings is different, and the level and uniformity cannot be achieved, resulting in an increase in the internal void ratio of the board. A certain density gradient is formed, and the thickness sta...
