Abstract

The invention is an ivory technical wooden fan blank bleaching technique, technical steps: (1), weight percent of each component in bleacher solution: 20-50% concentration oxydol 0.93457-0.71428, 5-30% concentration sodium hydroxide solution 0.01869-0.21428 and industrial alcohol 0.04674-0.071428; (2), bleaching: soaking separated fan blanks in the oxydol and sodium hydroxide solution for 5-10 hours, and fan edge in the oxydol, sodium hydroxide solution and alcohol solution for 10-12 hours; (3), washing: washing qualified fan blanks and edges by clear water to eliminate the solutions; (4)separating: making the fan blanks and edges whose whiteness is lower than 70% repeat the step (2); (5), drying: cold-placing the fan blanks and edges to dry, where water ratio is up to 12-14%. It keeps original property of timber, strong color lightfastness, etc.

Description

technical field [0001] The invention relates to a bleaching technology for making ivory craft wood fan blanks by bleaching and toning treatment of ordinary grouper wood, and belongs to the technical field of bleaching and toning treatment of wood fan blanks. Background technique [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 Color treatment technology has not been found so far, such as the traditional bleaching technology can not meet the bleaching requirements of wood fan blanks 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....
