NCB活性氧助剂在洗衣粉中的应用

Application study of neutral crystal bleaching agent NCB

从产品的热稳定性、复配后稳定性、坯布的清洗效果、彩布的清洗效果和杀菌效果5个方面对NCB活性氧助剂和传统的固体漂白剂过碳酸钠进行了对比研究。结果表明,NCB活性氧助剂3 h的分解率为5.43%,好于包衣过碳酸钠的分解率78.38%;复配10%的NCB洗衣粉,常温分解率为13.0%,好于过碳酸钠的72.5%;以1∶10质量比向洗衣粉中添加NCB对白棉坯布的白度保持率达106%,高于过碳酸钠的103.3%,对彩布的清洗效果优于过碳酸钠;杀菌效果与相同添加量的过碳酸钠相当。

NCB is blended with washing powder,and contrasted with sodium percarbonate in thermal stability experiments, storage stability, bactericidal effect, experimental decontamination of white fabric and color fabric to study the NCB performance. The results reveal that the dissolution rate of NCB is 5.43% and the dissolution rate of sodium percarbonate is 78.38% ;added 10% NCB in washing powder,the powder＇s dissolution rate is 13.0% better than it of sodium percarbonate ,respectively, added NCB and sodium percarbonate to washing powder, the whiteness rention rate of white cotton cloth can be increased to 106% and 103.3% after washed in the same circumstance .
