单板漂白技术探讨

Discussion on Veneer Bleaching Technology

本文通过三个单板漂白实例分析 ,论述了漂白配方、漂白工艺对单板的漂白效果及漂白加工成本的影响。试验结果表明 :当漂白液配比为双氧水 35～ 4 0 g/ L(浓度 10～ 15 % ) ,硅酸钠 5～ 6 g/ L,SETI- 0 1为 3.5～ 4 .0 g/ L,漂白液 p H9.5～ 11;漂白条件为浴比 1∶ 7,浸渍温度 85～ 90℃ ,浸渍时间 6 0～ 80

In this article, the influences of bleaching solution formula and technology on bleaching effect and processing cost were analysed. Results showed that satisfied bleaching result could be acquired when bleaching solution made up by hydrogen peroxide solution (H 2O 2) 35～40 g/L, sodium silicate (Na 2SiO 3) 5～6 g/L, SETI 01 3.5～4.0 g/L, pH value 9.5～11, under bleaching processing condition with bath ratio of 1∶7, soaking temperature of 85～90 ℃ and soaking time for 60～80 min.
