Problems solved by technology

The above scheme uses wood to make fan blades, but there are still some problems in the fan blades. For example, the fan blades made of logs are easy to deform and crack after a long time of use, and the use of fiberboard or composite board will cause stiffness due to rigidity. Insufficient deflection and deformation may even occur, and the interlayer may fall off

Abstract

The invention relates to eucalyptus vane plywood and a manufacturing method thereof. The eucalyptus vane plywood comprises a core plate and panels adhering to the two surfaces of the core plate. The core plate is composed of three veneers, and core plate adhesives are smeared between every two adjacent veneers. The veneers are eucalyptus veneers formed by rotationally cutting eucalyptus logs. The core plate adhesives are composed of E0 urea formaldehyde resin adhesives, flour, ammonium chloride and ferrous powder in the ratio of 1:0.4:0.006:0.001. The panels are bintangor panels formed by rotationally cutting bintangor logs. Panel adhesives are smeared between the core plate and the panels and are composed of E0 urea formaldehyde resin adhesives and flour in the ratio of 1:0.5. The eucalyptus vane plywood is simple in structure, good in rigidity, free of deformation and cracking, easy to manufacture and capable of effectively reducing the production cost, improving the quality of vanes and prolonging the service life of the vanes.

Description

technical field [0001] The invention belongs to the application field of wood-based panels, and in particular relates to a eucalyptus plywood fan blade board and a manufacturing method thereof. Background technique [0002] The electric fan commonly used in people's daily life is usually made of metal or plastic. However, experience tells us that although metal fan blades have high strength and good rigidity, they are expensive and costly to manufacture. Moreover, metal fan blades are heavy in weight, high in power consumption, easy to peel off paint and rust after a long time of use, and difficult to maintain. Although plastic fan blades are cheap and light in weight, they are prone to fracture and damage due to low strength and poor rigidity due to aging. People hope that a fan blade material with high strength, good rigidity, light weight, aging resistance, beautiful and practical, and cheap price will come out. Wood, a pure natural renewable material, has the character...
