“scouring agent”(洗涤剂/精练剂)是工业领域中用于清除材料表面杂质的化学制剂,常见于纺织、金属加工等行业。其主要作用是通过物理或化学方式剥离污渍、油脂、氧化物等残留物,使基材达到清洁或可后续加工的状态。
在纺织工业中,scouring agent通常由碱性化合物(如氢氧化钠)和表面活性剂组成,用于去除天然纤维中的蜡质、果胶等杂质,提升染色均匀性。例如,棉布预处理过程中需通过高温碱煮去除约8%-12%的天然杂质(《纺织化学处理手册》,中国纺织出版社)。
金属加工领域则多采用酸性scouring agent(如磷酸溶液),通过螯合反应清除金属表面的氧化层。这种方法能使不锈钢表面粗糙度降低至Ra≤0.8μm,符合GB/T 8923.1-2011标准规定的清洁度要求(《表面处理工程技术规范》,机械工业出版社)。
“Scouring agent”是一个复合词,由“scouring”和“agent”构成,需分别解析其含义后综合理解:
Scouring(擦洗/冲刷)
Agent(作用剂)
指一类专门用于擦洗、清洁或精练的化学制剂,常见用途包括:
