3.2.1設(she)備檢查

Step 1

根(gen)據需(xu)要制(zhi)備的顆粒物類型檢查罐(guan)(guan)體中(zhong)的氣溶(rong)(rong)(rong)(rong)膠溶(rong)(rong)(rong)(rong)液(ye)(ye)是否渾濁或(huo)者不足，如果溶(rong)(rong)(rong)(rong)液(ye)(ye)渾濁，需(xu)用清水清洗罐(guan)(guan)體，重(zhong)新添(tian)加(jia)溶(rong)(rong)(rong)(rong)液(ye)(ye)；如溶(rong)(rong)(rong)(rong)液(ye)(ye)不足需(xu)重(zhong)新添(tian)加(jia)溶(rong)(rong)(rong)(rong)液(ye)(ye)，鹽(yan)(yan)性(xing)與油性(xing)溶(rong)(rong)(rong)(rong)液(ye)(ye)均(jun)加(jia)入(ru)至罐(guan)(guan)體的一半左右。鹽(yan)(yan)性(xing)溶(rong)(rong)(rong)(rong)液(ye)(ye)添(tian)加(jia)到鹽(yan)(yan)性(xing)罐(guan)(guan)中(zhong)，油性(xing)溶(rong)(rong)(rong)(rong)液(ye)(ye)添(tian)加(jia)到油性(xing)溶(rong)(rong)(rong)(rong)液(ye)(ye)中(zhong)。若使用NaCl氣溶膠溶液，需定期(qi)清(qing)洗發塵器及其(qi)噴(pen)嘴，建議(yi)一(yi)周一(yi)次。

Step 2

檢查(cha)夾具中(zhong)是否有異(yi)物(wu)，檢查(cha)夾具上下的硅膠墊是否沾有上一次測試遺留的布屑，如有異物或(huo)雜質，請及時清理干凈。平時使(shi)用也要注意保持測試夾具內干燥潔凈，不(bu)得掉(diao)入異物(wu)，需用酒精擦拭。
