ʻO ka ʻinoʻino kekahi o nā pōʻino o ka ʻeha poʻo o nā mea hana kemika. Hiki i ka mālama pono ʻole ke hōʻino i nā mea hana, a i ʻole ke kumu o ka pōʻino a i ʻole ka pōʻino. Wahi a nā helu helu kūpono, ma kahi o 60% o ka pōʻino o nā mea hana kemika ke kumu o ka corrosion. No laila, pono e noʻonoʻo ʻia ke ʻano ʻepekema o ke koho ʻana i nā mea i ke koho ʻana i ka valve kemika.
Nā mea nui o ke koho ʻana i nā mea:
1. ʻO ka sulfuric acid kahi mea waiwai nui o ka ʻoihana me ka nui o ka hoʻohana ʻana. ʻO ka sulfuric acid o nā ʻokoʻa ʻokoʻa a me nā mahana he ʻokoʻa nui i ka corrosion o nā mea. ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion, akā ʻaʻole kūpono ia no ke kahe kiʻekiʻe o ka sulfuric acid a ʻaʻole kūpono no ka hoʻohana. ʻO ka mea o ka pahu pahu. No laila, hana pinepine ʻia nā ʻōmole paila no ka sulfuric acid i ka hao hao kiʻekiʻe-silikona a me ke kila kila kila kiʻekiʻe.
2. ʻAʻole kūpaʻa ka hapa nui o nā mea metala i ka waika hydrochloric corrosion. Kū'ē i nā mea metala, ʻo ka hapa nui o nā mea metala ʻole ke kūpaʻa maikaʻi i ka waika hydrochloric. No laila, ʻo nā kiwi kīpē a me nā pahu plastik i hoʻopaʻa ʻia me ka waika hydrochloric nā koho maikaʻi loa no ka lawe ʻana i ka waika hydrochloric.
3. ʻAka Nitric, ʻo ka hapa nui o nā metala ua ʻino a luku ʻia i loko o 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. No ke kiʻekiʻe wela o ka nitric acid, hoʻohana pinepine ʻia ka titanium a me ka titanium. Nā mea huila.
4. 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 kūpaʻa acetic acid maikaʻi loa, ʻoi aku ka paʻakikī no ka wela kiʻekiʻe a me ke kiʻekiʻe o ka acetic acid a i ʻole nā mea hoʻoheheʻe corrosive ʻē aʻe. I ka wā e pono ai, hiki ke koho ʻia nā kiwi kila kila kila kiʻekiʻe a i ʻole nā kiwi fluoroplastic.
