Description
Technical Field
The invention belongs to the technical field of clothes hanger processing, and particularly relates to a manufacturing method of a eucalyptus clothes hanger.
Background
The eucalyptus grows rapidly, and the rotation cutting period is short, so that the eucalyptus is an important artificial forest species in China. Because eucalyptus has the defects of easy deformation and cracking, poor dimensional stability and the like, the application range of eucalyptus is limited, most of eucalyptus artificial forest woods are mainly used for the production of paper making industry at present, and the utilization of eucalyptus in the wood processing industry is always in the lagging level. Particularly, in the processing and manufacturing industry of the eucalyptus clothes hangers, because the eucalyptus material is not tough, the eucalyptus clothes hangers are easy to break during processing and use, and the service life is not long, the market share of the eucalyptus clothes hangers is very small for a long time, and particularly, the eucalyptus clothes hangers with high quality do not exist in the eucalyptus clothes hangers. The existing manufacturing method of the eucalyptus clothes hanger is that log is sawn into blank plates, the blank plates are directly dried, then the blank plates are shaped and processed, and then finished products are obtained after painting and drying. The eucalyptus clothes hanger manufactured by the technical scheme has high rejection rate, and the finished product is easy to warp and deform, has cracks and mildew, and can be corroded by moths such as termites. The log is easy to crack and deform in sawing and drying, the outturn rate is low, and the product has poor dimensional stability, thereby influencing the processing and the use of the eucalyptus clothes rack.
