Processing technology of large fan blade sandwich balsa wood material

Abstract

The invention discloses a processing technology of a large fan blade sandwich balsa wood material. The processing technology of the large fan blade sandwich balsa wood material comprises the following steps of preparation before processing, polishing of square timber, dust removal of the square timber, drying after coating conducted on the surface of the square timber, shallow groove forming of the square timber, punching of the square timber, cloth pasting of the square timber, film covering treatment of the surface of the timber and post-treatment processing of the square timber. The invention relates to the field of processing of sandwich balsa wood materials, in particular to the processing technology of the large fan blade sandwich balsa wood material, which has the beneficial effects that the water content is controlled to be below 20 percent before processing, so that cracking and deformation of wood products processed in the later period can be avoided, the density of the wood can be controlled through square cut, and relevant requirements are met; and the surface of the square timber is coated and then dried, so that the coated preservative and the treatment liquid can better permeate into the square timber at the drying temperature, and a better effect is achieved.

Description

technical field [0001] The invention relates to the processing field of a sandwich balsa wood material, in particular to a processing technology of a large fan blade sandwich balsa wood material. Background technique [0002] Wood has the advantages of light weight, high strength-to-weight ratio, good elasticity, impact resistance, rich and beautiful texture and color, and easy processing. It has been listed as an important raw material since ancient times. Wood processing has low energy consumption, less pollution, and renewable resources. , also occupies an important position in the national economy. Now the products are used in wood products such as building components, furniture, vehicles, ships, stationery, packaging containers, etc., as well as wood-based products such as various wood-based panels, glued wood, etc., so that the wood industry has formed an independent industrial system. Sand wood is one of the fastest growing trees and the lightest wood in the world. Al...

Problems solved by technology

However, there are certain disadvantages in the existing balsa wood processing. First, the preparation before processing is relatively simple. If the water content is not well controlled, it will affect the processing quality in the later stage. The coating and drying treatment is relatively simple, and the coating is not easy. embalming and drying
