Inā ʻaʻole hiki ke hoʻohana ʻia kahi pūnāwai kinoea kila inā hiki ke hoʻopili ʻia ka palapala noi me ka wai a i ʻole ka makū ma kekahi ʻano. E ʻeleʻele ka pūnāwai kinoea, hōʻike i nā ʻano ʻino a me ka haki. ʻO kahi mea āu e makemake ai e pale.
ʻO kahi koho kūpono he pūnāwai kinoea kila. ʻAʻole ʻino kēia mea a hoʻokō pū i kekahi mau koi maʻemaʻe - kahi mea nui loa i ka ʻoihana kemika a me ka ʻoihana meaʻai. MaʻO Guangzhou Tieying Spring Technology Co., Ltdhāʻawi mākou i ʻelua ʻano o ke kila kila, ʻo ia hoʻi ke kila kila 304 a me ke kila kila 316. ʻOiaʻiʻo nō hoʻi mākou e hauʻoli e wehewehe i ka ʻokoʻa ma waena o lākou.
ʻO ka ʻokoʻa ma waena o 304 a me 316:
ʻO ka ʻokoʻa nui ma waenakila kohu ʻole304 a me ke kila kila 316 i loko o ka haku mele 'ana o nā mea. Loaʻa i ke kila kila 316 ka 2% molybdenum, ka mea i ʻoi aku ke kūpaʻa o ka mea i ka crevice, pitting a me ka stress corrosion cracking. ʻO ka molybdenum i loko o ke kila kila 316 ka mea i emi iki i ka chlorides. ʻO kēia waiwai i hui pū ʻia me ka pākēneka kiʻekiʻe o ka nickel e hoʻonui i ka pale ʻana o ke kila kila 316.
ʻO ka wahi nāwaliwali o ke kila kila 304 kona naʻau i nā chlorides a me nā waikawa, hiki ke hoʻoulu i ka corrosion (local a i ʻole). ʻOiai kēia drawback, apunawai kinoeahana ʻia me ke kila kila 304 he hopena maikaʻi loa ia no nā noi home-garda-a-kukina.
Ke koho ʻana i kahi mea no ka puna wai, pono e noʻonoʻo i nā kūlana kaiapuni kikoʻī e ʻike ʻia ai ka pūnāwai. Inā pili ke kaiapuni i ka ʻike ʻana i nā mea ʻino, ʻoi aku ka wai paʻakai a i ʻole nā kemika paʻakikī, ʻoi aku ka maikaʻi o ka 316 stainless steel no kona kūpaʻa ʻana i ka corrosion. Eia nō naʻe, inā he kumu koʻikoʻi ke kumukūʻai a ʻoi aku ka liʻiliʻi o ke kaiapuni, lawa paha ke kila kila 304 no ka noi.
