Hiki i ka hui ke hoʻopilikino i ka hana ʻana o nā ʻano like ʻole o ke aniani kila stainless steel, hoʻokipa e hoʻouna i leka uila e nīnau mai iaʻu
1. Ma luna o ka ʻili o ke kila kila, aia nā waiho o ka lepo a i ʻole nā ʻāpana metala heterogeneous i loaʻa nā mea metala ʻē aʻe.I loko o ka ea humid, ka wai condensed ma waena o nā waihona a me ke kila kuhiliʻole e hoʻopili i nā mea ʻelua i kahi micro-battery, e hoʻoulu ai i kahi hopena electrochemical , ua pōʻino ke kiʻi pale, i kapa ʻia ʻo electrochemical corrosion.
2. ʻO nā waiʻawaʻawa (e like me nā mea kanu, noodle soup, sputum, a me nā mea'ē aʻe) pili i kaʻili o ke kila kila.Ma ke alo o ka wai a me ka oxygen, hoʻokumu ʻia nā ʻakika organik, a ʻo nā waikawa organik e hōʻino i ka ʻili metala no ka manawa lōʻihi.
3. Pili ka ʻili o ke kila kila i nā mea i loaʻa i nā ʻakika, alkalis a me nā paʻakai (e like me ka wai alkali a me ka wai lime e pāpaʻi ana mai nā paia hoʻonaninani), e hoʻoulu ai i ka ʻino kūloko.
4. Ma ka ea haumia (e like me ka lewa i loaʻa ka nui o ka sulfide, carbon oxide, nitrogen oxide), i ke alo o ka wai condensed, ka hoʻokumu ʻana o ka sulfuric acid, nitric acid, acetic acid wai kiko, e hoʻoneʻe ai i ke kino. ma luna o nā kūlana hiki ke hana i ka pale kiʻiʻoniʻoni ma luna o ke kila kuhiliʻole.ʻO ka pōʻino ke kumu o ka pala.
ʻO ke kūpaʻa o ka corrosion o ke kila kila e hilinaʻi nui ʻia i kāna hui ʻana (chromium, nickel, titanium, silicon, aluminika, manganese, a me nā mea ʻē aʻe) a me ka hale o loko, a ʻo ka hana nui he chromium.Loaʻa i ka Chromium ke kūpaʻa kemika kiʻekiʻe a hiki ke hana i kahi kiʻiʻoniʻoni passivation ma ka ʻili kila e hoʻokaʻawale i ka metala mai ka honua o waho, e pale i ka pā kila mai ka hoʻoheheʻe ʻia, a hoʻonui i ke kūpaʻa corrosion o ka pā kila.Ma hope o ka luku ʻia ʻana o ka kiʻiʻoniʻoni passivation, hoʻemi ke kūpaʻa corrosion.
ʻO ka pā kila kila he huaʻōlelo maʻamau no ka pā kila kuhiliʻole a me ka pā kila kūpaʻa waika.Hoʻokomo ʻia i ka hoʻomaka ʻana o kēia kenekulia, ua hoʻokumu ka hoʻomohala ʻana i ka pā kila stainless i kahi kumu waiwai nui a me ka ʻenehana no ka hoʻomohala ʻana i ka ʻoihana hou a me ka holomua ʻepekema a me ka ʻenehana.Nui nā ʻano o nā pā kila kila me nā waiwai like ʻole.Ua hoʻokumu mālie ʻo ia i kekahi mau ʻāpana i ke kaʻina hoʻomohala.Wahi a ka hale, ua māhele ʻia i ʻehā mau ʻāpana: austenitic stainless steel, martensitic stainless steel (me ka paʻakikī paʻakikī o ka ua), ferritic stainless steel, a me austenitic plus ferritic duplex stainless steel.Hoʻokaʻawale ʻia ka hui kemika nui a i ʻole kekahi mau hiʻohiʻona o ka pā kila i loko o ka chromium stainless steel plate, chromium nickel stainless steel plate, chromium nickel molybdenum stainless steel plate, haʻahaʻa carbon stainless steel plate, high molybdenum stainless steel plate, high clean clean stainless steel plate. , etc. E like me nā hiʻohiʻona hana a me ka hoʻohana ʻana i ka pā kila, ua māhele ʻia i ka nitric acid-resistant stainless steel plate, sulfuric acid-resistant stainless steel plate, pitting corrosion-resistant stainless steel plate, stress corrosion-resistant stainless steel plate. , kiʻekiʻe-ikaika kuhiliʻole kila pā, etc. E like me ka hana 'ano o ka mea kila, ua maheleia i ka haʻahaʻa wela kuhiliʻole pā kila, non-magnetic kuhiliʻole pā kila, manuahi-ʻoki kuhiliʻole pā kila, superplastic kuhiliʻole papa, etc. ʻO ke ʻano hoʻokaʻawale maʻamau ʻo ia ka hoʻokaʻawale ʻana e like me nā ʻano hana oka pā kila, nā hiʻohiʻona hoʻohui kemika o ka pā kila a me ka hui pū ʻana o nā mea ʻelua.Hoʻokaʻawale ʻia i loko o ka martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel and precipitation hardening stainless steel, etc.Ka laulā o ka hoʻohana ʻO nā hoʻohana maʻamau: nā mea hoʻololi wela o ka pulp a me ka pepa, nā lako mīkini, nā mea pena, nā mea hana kiʻiʻoniʻoni, nā paipu, nā mea waho no nā hale ma nā kahakai, etc.
ʻO ka pā kila kila he ʻili maʻemaʻe, plasticity kiʻekiʻe, paʻakikī a me ka ikaika mechanical, a kūpaʻa i ka corrosion e nā waikawa, nā kinoea alkaline, nā hopena a me nā media ʻē aʻe.He kila hoʻoheheʻe ʻole ʻole ia, akā ʻaʻole ʻeleʻele loa.
