He aha nā hana kikoʻī a nā surfactants e pāʻani ai i nā noi hoʻomaʻemaʻe pickling?

1 E like me nā mea pale noe ʻākaika

I ka wā pickling, hydrochloric acid, sulfuric acid, a i ʻole nitric acid e pane ʻole me ka substrate metala i ka wā e hana ai me ka ʻōpala a me ka unahi, e hoʻohua ana i ka wela a me ka nui o ka noe waikawa. ʻO ka hoʻohui ʻana i nā surfactants i ka hopena pickling, ma muli o ka hana o kā lākou mau pūʻulu hydrophobic, hoʻokumu i kahi uhi kiʻiʻoniʻoni linear insoluble ma ka ʻili o ka hopena pickling. Me ka hoʻohana ʻana i ka hana ʻūhā o nā surfactants, hiki ke hoʻopaʻa ʻia ka hoʻoheheʻe ʻana o ka noe. ʻO kaʻoiaʻiʻo, hoʻohui pinepine ʻia nā mea hoʻopaneʻe corrosion i nā hopena pickling, kahi e hōʻemi nui ai i ka nui o ka corrosion metala a hoʻemi i ka hoʻomohala hydrogen, a laila e hōʻemi ana i ka noe waikawa.

2 E like me ka hui ʻana i ka hoʻomaʻemaʻe ʻana a me ka hoʻomaʻemaʻe ʻana

I ka hoʻomaʻemaʻe ʻana i nā mea ʻenehana maʻamau, inā loaʻa nā ʻāpana ʻaila i loko o ka fouling, e hana mua ʻia ka hoʻomaʻemaʻe alkaline e hōʻoia i ka maikaʻi pickling, a ma hope o ka hoʻomaʻemaʻe waika. Inā hoʻohui ʻia kahi nui o ka degreasing agent, ka mea nui nonionic surfactants, i ka hopena pickling, hiki ke hoʻohui ʻia nā ʻanuʻu ʻelua i hoʻokahi kaʻina. Eia kekahi, ʻo ka hapa nui o nā mea hoʻomaʻemaʻe hoʻomaʻemaʻe paʻa ka nui o ka sulfamic acid a loaʻa kekahi nui o nā surfactants, thiourea, a me nā paʻakai inorganic, i hoʻoheheʻe ʻia me ka wai ma mua o ka hoʻohana ʻana. ʻO kēia ʻano mea hoʻomaʻemaʻe ʻaʻole wale ka maikaʻi o ka ʻōpala a me ka wehe ʻana i ka unahi a me nā waiwai inhibition corrosion akā hoʻopau pū kekahi i ka aila.
