Problems solved by technology

[0002] An all-bamboo craft fan and the bleaching treatment process adopted in the preparation process is a conventional method, the patent publication number is CN 1124123A, and its processing object is bamboo, but for the bleaching and conditioning of the wood fan blank with grouper The color treatment technology has not been discovered so far. For example, the traditional bleaching technology cannot meet the bleaching requirements of the wood fan blank with grouper wood as raw material.
As we all know, grouper wood (commonly referred to as the product name of Photinia and Rhaphiolepis in Rosaceae Photinia and Rhaphiolepis wood) products are not high in quality and grade due to color difference and other reasons. Can not meet the quality requirements of the product
