Hōʻike: He haʻahaʻa hydrogen sodium uhi electrode kūikawā no ke kila aluminized.E hoʻohana i ka DCEP (direct current electrode positive), a hiki ke wili ʻia ma nā kūlana āpau me ka hana pōkole pōkole.Hiki ke wili pololei ʻia ʻo J557SLA me ka ʻole o ka wehe ʻana i ka papa aluminized ma ka ʻili o ka groove ma mua o ke kuʻi ʻana.Akā ʻo ka J557SLB pono e wehe i ka papa aluminized ma ka ʻili o ka groove ma mua o ke kuʻi ʻana.

Hoʻohana: Hoʻohana ʻia ia no ka wili ʻana i ka hale kila aluminized ma lalo o ke ʻano corrosion o ka hydrogen sulfide, sulfur, ammonia, ammonium bicarbonate a me ka hydrogen nitrogen me ka mahana hana ma lalo o 540 ° C.E like me nā paipu paila, nā lako hoʻomaʻemaʻe ʻaila, nā mea hoʻomomona a me nā paipu mahu, etc.
