ʻO ke kila kila ke ʻano o ke kila kila kiʻekiʻe e hiki ke pale aku i ka ʻino i ka ea a i ʻole ke kino kino.He ili nani a me ke kū'ē corrosion maikaʻi.ʻAʻole pono ia e hana i ka mālama ʻana i ka ʻili e like me ke kala kala, akā hoʻohana ʻo ia i nā waiwai kūlohelohe o ke kila kila.Hoʻohana ʻia ia i kahi ʻano kila multifaceted.
I kēia mau lā, ua hoʻohana nui ʻia nā huahana stainless steel i ka ʻoihana a me ke ola.No laila pehea e ʻike ai i ka ʻoiaʻiʻo o ke kila kila?Ma lalo iho, na ka mea hoʻoponopono Pelekāne e lawe iā ʻoe e hoʻomaopopo:
1. Keʻano qualitative kemika
ʻO ke ʻano kemika qualitative kahi ala ʻike e ʻike ai inā loaʻa ka nickel i ke kila stainless magnetic.ʻO ke ʻano o ka hoʻoheheʻe ʻana i kahi ʻāpana liʻiliʻi o ke kila kila i loko o ka aqua regia, hoʻoheheʻe i ka wai ʻakika me ka wai maʻemaʻe, hoʻohui i ka wai amonia e hoʻopau ai, a laila hoʻokomo mālie i ka nickel reagent.Inā aia kekahi mea ʻulaʻula ʻeleʻele e lana ana ma luna o ka ʻili wai, ʻo ia hoʻi, aia ka nickel i loko o ke kila kila;inā ʻaʻohe mea ʻulaʻula velvet, ʻo ia hoʻi ʻaʻohe nickel i loko o ke kila kila.
2. Nitric acid
ʻO kahi hiʻohiʻona koʻikoʻi o ke kila kila ʻo ia kona kūpaʻa kūʻokoʻa i ka waika nitric concentrated a dilute.Hiki iā mākou ke hoʻohana i ka waikawa nitric e hoʻoheheʻe ʻia i nā huahana kila kila, hiki ke ʻike maopopo ʻia, akā pono mākou e hoʻolohe i ka ʻoiaʻiʻo o nā kila kila kiʻekiʻe 420 a me 440 i hoʻoheheʻe ʻia i ka wā o ka hoʻāʻo ʻana i ka nitric acid point, a me nā metala non-ferrous. e hui koke i ka waika nitric concentrated.ʻinoʻino.
3. Ho'āʻo kiko keleawe keleawe
Wehe i ka papa oxide ma ke kila, kau i kahi kulu o ka wai, holoi me ke keleawe sulfate, inā ʻaʻole ia e hoʻololi i ka waihoʻoluʻu ma hope o ka hamo ʻana, ʻo ia ke kila kila;hao hao.
4. Kala
ʻO ka ili o ka ʻakika-holoi kuhiliʻole kila: chrome-nickel kuhiliʻole kila he silvery keʻokeʻo jade kala;ʻO ke kila kila kila keʻokeʻo keʻokeʻo a ʻālohilohi;ua like ke kala o ka chrome-manganese-nitrogen stainless steel me ka chrome-nickel stainless steel a ʻoi aku ka māmā.ʻO ke kala ili o ke kila kuhili ʻole ʻole: ʻeleʻele-keʻokeʻo ke kila chrome-nickel, ʻeleʻele-ʻeleʻele ka chrome-steel, a ʻeleʻele ka chrome-manganese-nitrogen.ʻO ke kila chrome-nickel i hoʻoheheʻe ʻole ʻia me ka ʻili keʻokeʻo kālā keʻokeʻo.
