基于响应面分析法的人发漂白铁媒预处理工艺优化
|
摘要
铁媒预处理是黑色人发双氧水漂白中极为重要的一环,其影响因素众多,为寻找最佳处理工艺,分析各单因素及相互作用对人发漂白的影响,并对处理工艺进行优化。以草酸用量、硫酸亚铁用量、p H值、处理时间、处理温度为因素,以白度和断裂强力为指标,采用响应面分析法对人发铁媒预处理工艺进行优化。通过单因素实验,以Box-Behnken中心组合实验原理和响应面分析法研究各自因素及其相互作用,并对各因素的影响程度进行分析。结果表明:最佳铁媒预处理工艺为:硫酸亚铁9. 5 g/L,草酸3 g/L,p H值1,时间95 min,温度70℃。在此铁媒预处理工艺下,漂白后人发的白度值为63. 66,断裂强力为68. 20 c N。
Black human hair bleaching pretreated with iron as mordant is a very important method.In order to optimize the treatment process,the influence factors and the processing technology were studied. The oxalate dosage,ferrous sulfate dosage,pH value,treatment time and treatment temperature were used as factors,whiteness and breaking strength were taken as indexes to optimize the human hair iron mordant pretreatment process by response surface analysis. Through single-factor experiments,BoxBehnken central combination experimental principle and response surface analysis of their respective factors and their interactions,as well as the extent of the impact of various factors were analyzed. The results showed that the best iron mordant pretreatment process were: ferrous sulfate 9. 5 g/L,oxalic acid3 g/L,pH value 1,95 min temperature 70 ℃. In this iron media pretreatment process,white hair after bleaching L value was 63. 66,breaking load was 68. 20 cN.
