1. Sulfuric acid E like me kekahi o nā media corrosive ikaika, ʻo ka sulfuric acid he mea koʻikoʻi o ka ʻoihana waiwai me ka laulā nui o ka hoʻohana. ʻOkoʻa loa ka ʻino o ka ʻakika sulfuric me nā ʻokoʻa a me nā mahana. No ka ʻakika sulfuric concentrated me ka manaʻo ma luna o 80% a me ka mahana ma lalo o 80 ℃, ʻoi aku ka maikaʻi o ka corrosion resistance, ke kila kalapona a me ka hao, akā ʻaʻole kūpono ia no ka waika sulfuric kahe kiʻekiʻe. ʻAʻole kūpono ia no ka hoʻohana ʻana ma ke ʻano he mea no nā kiwi paila; ʻO nā kila kulika maʻamau e like me 304 (0Cr18Ni9) a me 316 (0Cr18Ni12Mo2Ti) i kaupalena ʻia no ka media sulfuric acid. No laila, hana pinepine ʻia nā ʻōmole paila no ka lawe ʻana i ka sulfuric acid i ka hao kiʻekiʻe-silikona (ka paʻakikī i ka hoʻolei ʻana a me ka hana ʻana) a me ke kila kila kila kiʻekiʻe (alloy 20). ʻOi aku ka maikaʻi o ke kūʻē ʻana o nā fluoroplastics i ka sulfuric acid, a ʻoi aku ka maikaʻi o nā pahu fluorine-lined.
2. ʻO ka ʻakika acetic kekahi o nā mea ʻino loa i loko o nā ʻakika organik. E ʻino nui ʻia ke kila maʻamau i ka ʻakika acetic ma nā ʻano a me nā mahana a pau. ʻO ke kila kila he mea maikaʻi loa ke kūpale acetic acid. 316 kila kuhiliʻole i loko o ka molybdenum ua kūpono no ke kiʻekiʻe wela a me ka Dilute acetic acid mahu. No nā koi koi e like me ke kiʻekiʻe kiʻekiʻe a me ke kiʻekiʻe o ka acetic acid a i ʻole nā mea hoʻoheheʻe corrosive ʻē aʻe, hiki ke koho ʻia nā kiʻekiʻe kiʻekiʻe o ke kila kila kila a i ʻole nā kiwi fluoroplastic.
3. Hydrochloric acid ʻO ka hapa nui o nā mea metala ʻaʻole kūʻokoʻa i ka corrosion acid hydrochloric (me nā mea kila stainless steel), a hiki ke hoʻohana wale ʻia ka ferro-molybdenum kiʻekiʻe i loko o ka waikawa hydrochloric ma lalo o 50 ° C a me 30%. Kū'ē i nā mea metala, ʻo ka hapa nui o nā mea metala ʻole ke kūpaʻa maikaʻi ʻana i ka waika hydrochloric, no laila, ʻo nā kiwi kaila a me nā kiwi plastik (e like me polypropylene, fluoroplastics, etc.) ʻo ia ka koho maikaʻi loa no ka lawe ʻana i ka waika hydrochloric.
4. Nitric acid. Hoʻopili koke ʻia ka hapa nui o nā metala i ka waikawa nitric. ʻO ke kila kila ka mea hoʻohana nui ʻia i ka nitric acid resistant material. Loaʻa iā ia ke kūpaʻa corrosion maikaʻi i nā manaʻo a pau o ka waikawa nitric ma ke ana wela. Pono e ʻōlelo ʻia ʻo ke kila kila i loaʻa ka molybdenum (e like me The corrosion resistance of 316, 316L) i ka waikawa nitric ʻaʻole i emi wale i ke kila kila maʻamau (e like me 304, 321), a i kekahi manawa haʻahaʻa. No ke kiʻekiʻe kiʻekiʻe nitric acid, titanium a me ka titanium alloy mea hoʻohana maʻamau.
