中文拼音 [qiāngòu]
鉛垢

lead fouling-

正常情況下,自來水裡不應該含有鉛,因為水管內部一般都會自然形成好幾層不同的礦物質積垢,可以把鉛抓住。But these mineral scales act as a trap for lead only as long as they remain insoluble ; a sudden shift in water chemistry can change that
但這些礦物質積垢只有在本身不溶解的狀態下,才具有抓住鉛的能力;水中化學性質的突然變化,就可能改變這一點。Test method for evaluating unleaded automotive spark - ignition engine fuel for electronic port fuel injector fouling
