Description

Manufacturing method of redwood furniture
Technical Field
The invention relates to the technical field of furniture manufacturing, in particular to a manufacturing method of redwood furniture.
Background
Rosewood is a general name of wood for high-end and rare furniture, and generally refers to red hardwood. Rosewood grows slowly, generally in the growth period of more than one hundred years, and is precious. With the increase of the demand of the mahogany furniture, the mahogany originally produced in China can not meet the supply demand, and most of the current domestic mahogany wood is imported from southeast Asia and other places.
The rosewood has long growth period, hard material, beautiful patterns, and obvious distinction between the core and the border material, and the border material is grey white, the core material is yellowish red or red, and can turn into mauve after being exposed in air for a long time. In the traditional processing of the redwood, most of the redwood is only selected to manufacture furniture, and the sapwood is discarded, which causes the shortage phenomenon of the redwood to a certain extent. Therefore, how to improve the material selection range during the processing of the padauk by optimizing the processing technology has very important significance.
The general process of manufacturing the redwood furniture comprises the following steps: selecting materials, cutting materials, drying, tenoning, carving, assembling, scraping and painting. Because the rosewood border material has lower hardness and is easy to deform and moth-eaten, the rosewood border material is generally excluded during material selection, and only a core material with hard texture is selected, particularly when a plurality of components need to be carved during the carving process, the rosewood core material with hard texture is required to be selected.
The Chinese patent with application publication number CN107553678A discloses a processing technology of redwood furniture, which comprises the steps of selecting materials, removing oil, tenoning, carving, cleaning, drying, assembling, scraping, grinding, painting and the like, wherein during oil removal, a sodium carbonate solution is adopted for soaking, then a mixed solution of acetone and sodium carbonate is adopted for soaking, the oil is removed fully, and the wear resistance of the furniture is improved by repeating painting for many times, so that the service life is prolonged. However, the painting times of the redwood furniture are too many, so that the overall processing period of the furniture is longer, and the processing efficiency is lower.
