本品系(xi)采(cai)(cai)用(yong)(yong)(yong)(yong)(yong)間接(jie)法制得的白(bai)色粉末,無味、無毒。密(mi)度(du)為5.6 g/cm3,在氯丁(ding)橡(xiang)(xiang)(xiang)膠(jiao)中(zhong)做硫(liu)化(hua)(hua)劑(ji)(ji)使用(yong)(yong)(yong)(yong)(yong)。主要用(yong)(yong)(yong)(yong)(yong)作(zuo)天(tian)然橡(xiang)(xiang)(xiang)膠(jiao)、合成橡(xiang)(xiang)(xiang)膠(jiao)促(cu)進劑(ji)(ji)的活化(hua)(hua)劑(ji)(ji),亦可(ke)作(zuo)補強劑(ji)(ji)和著色劑(ji)(ji)。作(zuo)為活化(hua)(hua)劑(ji)(ji),既能加(jia)快硫(liu)化(hua)(hua)速度(du),又能提高(gao)硫(liu)化(hua)(hua)程(cheng)度(du)。在用(yong)(yong)(yong)(yong)(yong)噻(sai)唑(zuo)類(lei)(lei)(lei)、次磺酰胺類(lei)(lei)(lei)、秋(qiu)蘭姆類(lei)(lei)(lei)、胍類(lei)(lei)(lei)促(cu)進劑(ji)(ji)時(shi),氧(yang)化(hua)(hua)鋅(xin)(xin)均可(ke)增加(jia)其活性(xing)。當(dang)用(yong)(yong)(yong)(yong)(yong)含(han)鋅(xin)(xin)促(cu)進劑(ji)(ji)時(shi)不必添加(jia)氧(yang)化(hua)(hua)鋅(xin)(xin)。在氯丁(ding)橡(xiang)(xiang)(xiang)膠(jiao)中(zhong)還起酸接(jie)受(shou)體作(zuo)用(yong)(yong)(yong)(yong)(yong)。單(dan)用(yong)(yong)(yong)(yong)(yong)氧(yang)化(hua)(hua)鋅(xin)(xin)作(zuo)硫(liu)化(hua)(hua)劑(ji)(ji)時(shi)，力學性(xing)能差，易焦(jiao)燒,宜(yi)與氧(yang)化(hua)(hua)鎂并用(yong)(yong)(yong)(yong)(yong)。在氯磺化(hua)(hua)聚乙烯橡(xiang)(xiang)(xiang)膠(jiao)中(zhong),因氧(yang)化(hua)(hua)鋅(xin)(xin)會催(cui)化(hua)(hua)生成氯化(hua)(hua)氫(qing),故不使用(yong)(yong)(yong)(yong)(yong)。在丁(ding)基橡(xiang)(xiang)(xiang)膠(jiao)采(cai)(cai)用(yong)(yong)(yong)(yong)(yong)醌類(lei)(lei)(lei)硫(liu)化(hua)(hua)體系(xi)時(shi),加(jia)入氧(yang)化(hua)(hua)鋅(xin)(xin)可(ke)延(yan)遲焦(jiao)燒,增加(jia)其熱穩定性(xing)。

本品可(ke)增加膠料的導熱性，在熱空氣(qi)硫化工藝上(shang)非(fei)常重要。對氧化鋅的質量要注意(yi)，應盡量降(jiang)低有害金(jin)屬含量(如(ru)銅、鐵(tie)等)。--般用量為5.0~10.0phr。與超促進劑并用時為1.0~2.0 phr。
