摘　　要：利用纳米TiO2、叶绿素添加剂、分散剂等有效成分对蔺草固色所用日本染土进行改性处理,在不影响原有固色工艺及固色效果前提下,可使改性后染土的实际用量在目前蔺草固色工艺的基础上降低70%左右,从而降低了固色成本。同时,通过控制染土的实际用量,使作业环境中粉尘浓度在现有基础上降低62%左右,粉尘中游离S iO2含量降低60%左右,从而使蔺草作业环境中的粉尘污染得到有效控制,工作环境得到改善。Nano TiO2, chlorophyl addition agents and dispersion agents were used to modify the dyed earth, which made the consumption of the modified dyed earth was decreased about 70% than now. And the original fixation technology and quality were kept constant. So the fixation cost was decreased greatly. At the meantime, the dust concentration of the workshop was decreased about 62% than now by controlling the dyed earth consumption. And the free silicon dioxide of the dust was also decreased about 60%, which made the dust pollution of rush workshop controlled effectively. And the purpose of improving the men working environment was realized.
