【摘要】 利用活性炭、双氧水对一种新合成的氮-磷系阻燃型复鞣剂进行脱色过程研究。选择脱色剂用量、脱色pH、脱色温度、脱色时间作为四个因素,最终得到最佳工艺条件:活性炭用量0.12g/mL,pH3.5,脱色温度55℃,脱色时间0.5h,脱色率可达56.6%;v(双氧水)/v(试样)=1:2,脱色温度50℃,脱色时间1h,脱色率可达73.5%;应用试验表明,此种阻燃型复鞣剂具有很好的阻燃和复鞣效果,经脱色后的阻燃型复鞣剂,其阻燃性能和复鞣性能均有不同程度的改变。综合考虑,确定活性炭为最佳脱色剂。更多还原

【Abstract】 Using activate carbon and hydrogen peroxide as decolorants to deal with the novel synthetic phosphorus-nitrogen flame retardanted retanning agent.The decolorant dosage,the pH,the decoloration temperature and the decoloration time were chosen as the four factors,and the optimal technological conditions were found as follows: activate carbon dosage 0.12 g/mL,pH 3.5,decoloration temperature 55℃,decoloration time 0.5 h,and the color removel rate could come up to 56.6﹪;v(hydrogen peroxide)/v(sample)= 1:2,decoloration temperature 50℃,decoloration time 1h,and the color removel rate could reach to 73.5﹪.After comprehensive consideration,active carbon was selected as the optimal decolorant.更多还原
