Sanding method of fast-growing wood

Abstract

The invention discloses a sanding method of fast-growing wood. The sanding method comprises the steps: (1) removing stains from the surface of the fast-growing wood, and then applying sanding auxiliaries to the surface of the fast-growing wood; (2) performing sanding treatment to the fast-growing wood with a disc sander, and the model of sanding materials is any one of 100#, 120# and 150#, wherein the substrate of the sanding materials is a fabric abrasive belt; abrasive materials comprise, by weight, 29-36 parts of brown corundum abrasives, 1-3 parts of magnesium borate, 4-7 parts of docosanamide and 1-2 parts of iodooctadecane; the abrasive materials are bonded with the substrate through adhesive. The sanding method of the fast-growing wood, provided by the invention, has the advantages of easy operation, low cost, and safety and environmental protection in the operation process, and the surface of the fast-growing wood sanded is free of burrs, and smooth and flat, so that convenience is provided for subsequent coating operation; and in the sanding process, the fast-growing wood is not broken, and the rate of finished products is high.

Description

technical field [0001] The invention belongs to the technical field of fast-growing wood processing, and in particular relates to a sanding method for fast-growing wood. Background technique [0002] Fast-growing wood species refer to tree species that grow fast, mature early, and have a short rotation period. The common ones in my country include Hongsen locust tree, poplar, eucalyptus, willow, etc. The wood made from these fast-growing tree species is called fast-growing wood. Soft, generally used as raw materials for papermaking, construction, board core materials, etc., and some are used to make furniture, but some treatments must be done to the wood, among which sanding treatment is an important treatment method in the field of fast-growing wood processing. Sanding of fast-growing wood refers to the use of specific sanding tools and materials to carry out necessary grinding and sanding on the unevenness of the product surface, fiber conduit uplift or abnormal conditions,...

AI Technical Summary

Problems solved by technology

[0003] However, during the actual sanding operation of the fast-growing wood, due to the soft texture of the fast-growing wood, the sanding effect is not significant, and there are still many burrs on the wood surface after sanding, and the fast-growing wood is in the process of sanding. Cracks are prone to occur, resulting in a high scrap rate. It can be seen that the existing sanding process is not effective in sanding fast-growing materials.
