ʻIkepili
1. Nā koi kumu no ka mālama ʻana i ka ʻili o nā huila kila kila
2. Hoʻohālikelike i nā ʻenehana lapaʻau maʻamau
3. Nā hāʻina lapaʻau kūikawā ma nā wahi paʻakikī
4. Nā hoʻolālā pale i nā kaiapuni corrosive
5. Nā mea nui no ke koho kaʻina hana a me ka mana maikaʻi
6. Nā hihia noi ʻoihana a me nā hiʻohiʻona ʻano
1. Nā koi kumu no ka mālama ʻana i ka ʻili o nā huila kila kila
ʻO ka hana ʻana o nā huila kila kila i loko o nā kaiapuni corrosive e pili ana i ka synergy ma waena o ke kūpaʻa corrosion o ka mea ponoʻī a me ke kaʻina hana lapaʻau. Ke lawe nei i ke kila kila 304/316 ma ke ʻano he laʻana, ʻo ka chromium content kahi kiʻiʻoniʻoni passivation, ʻo ia ke kumu no ka pale ʻana i ka corrosion, akā pono e hoʻoikaika ʻia i nā hiʻohiʻona aʻe:
ʻO ka ʻāʻili ʻana o ka chloride ion:I loko o nā kaiapuni kai a i ʻole nā kūlana paʻakai paʻakai, hiki ke luku ʻia ke kiʻi passivation.
Hoʻokaʻaʻike me ka pāpaʻi kemika:ʻO nā ʻakika a me ka alkali, nā mea hoʻoheheʻe organik, a pēlā aku.
Kiʻekiʻe wela a kiʻekiʻe haʻahaʻa:ʻO ka microbial corrosion a me ka oxidation reactions ua hoʻopaʻa ʻia i loko o kahi wahi wela a haʻahaʻa.
ʻAʻahu mīkini:ʻO ka hana pinepine ka mea e hōʻino ai i ka papa pale ili, e hoʻopōʻino ai i ka ʻāina.
No laila, pono e ho'okō 'ia nā pahuhopu 'ekolu: ho'onui i ke ola o ke ki'i passivation, ho'omaika'i i ka pa'akikī o ka ili, a ho'onui i ka hiki ke kū'ē-pollution.
2. Hoʻohālikelike i nā ʻenehana lapaʻau maʻamau
(1) Kaʻina hana lapaʻau mīkini
Lapaʻau Sandblasting (pana pana).
Ma ka hoʻopili ʻana i ka ʻili me nā ʻāpana one -wikiwiki kiʻekiʻe, ua hana ʻia kahi ʻano matte like ʻole (Ra 3.2-6.3μm). ʻO ka pōmaikaʻi, ʻo ia ka wehe ʻana i ka papa o ka oxide a hoʻomaikaʻi i ka hoʻopili ʻana o ka uhi, kahi kūpono no nā koi anti-slip o nā mea hana lima lima. Eia naʻe, pono e hoʻomaopopo ʻia ma hope o ka sandblasting, koi ʻia ka mālama passivation e hoʻihoʻi i ke kūpaʻa corrosion.
Lapaʻau kiʻi uea
E hoʻohana i ka hoʻoponopono kikokikona mechanical e like me nā laina pololei a me nā laina maʻamau e hoʻomaikaʻi ai i ka friction o ka paʻa lima. Hoʻohana maʻamau i nā huila lima lāʻau lapaʻau, akā hiki ke hōʻiliʻili ʻia ka media corrosive i loko o nā puʻupuʻu o ke ʻano, a koi ʻia kahi uhi pani.
(2) Ke kaʻina hana lāʻau kemika
Pickling passivation
Wehe i nā ion hao manuahi ma o ka waikawa nitric a i ʻole ka waika citric a hana hou i ke kiʻiʻoniʻoni passivation waiwai chromium. Ua hōʻike ʻia nā haʻawina e hoʻomaikaʻi ʻia ke kūpaʻa pitting o pickled 316L stainless steel ma 3.5% NaCl solution e 40%.
ʻO ka poli kemika
E hoʻoheheʻe i nā micro-protrusions o ka ʻili me ke au uila i loko o kahi electrolyte ʻakika e loaʻa ai ka hopena aniani me ka hoʻonui ʻana i ka mānoanoa o ke kiʻiʻoniʻoni passivation. He kūpono no nā huila lima meaʻai-e hoʻemi i ka pilikia o ka hoʻopili ʻana i ka maʻi bacteria.
(3) ʻenehana hoʻopaʻa kino
PVD (hoʻomoe mahu kino)
Deposit ceramic coatings such as TiN and CrN in a vacuum environment, with a surface hardness of more than HV2000, significantly improving wear resistance and salt spray resistance (>1000 hola me ka ʻulaʻula ʻole). Ke hoʻohana nei ka iPhone stainless steel middle frame i kēia kaʻina hana, a ua hoʻonui ʻia i ka hana ʻana i nā huila mea kani kiʻekiʻe.
3. Nā hāʻina lapaʻau kūikawā no nā kaiapuni paʻakikī
(1) Kaiapuni moana
ʻO -papa lehulehu: PVD CrN papa lalo + electrophoretic epoxy resin papa waho, me ka noʻonoʻo ʻana i ka paʻakikī a me ke kū'ē ʻana i ke komo ʻana o ka chloride ion.
Micro-arc oxidation: Al₂O₃ kiʻiʻoniʻoni ceramic i hana ʻia i loko o ka electrolyte, a ʻoi aku ka nui o ka pale ʻana i ka ʻinoʻino o ke kai ma mua o 3 mau manawa ma mua o nā hana kuʻuna.
(2) Kaiapuni corrosion
Polytetrafluoroethylene (PTFE) impregnation: Hoʻokomo ʻia nā ʻāpana PTFE i loko o nā pores o ka ʻili kila kila e hōʻemi i ka wahi pili ma waena o ka waikawa a me ka media alkali. Ma hope o ka mālama ʻana, ua hoʻonui ʻia ke ola o kahi huila petrochemical valve ma 98% sulfuric acid i 5 mau makahiki.
Pākuʻi Laser: Ua kāʻei ʻia ka pauka huila co-ma luna o ka ʻili i mea e hana ai i ka ʻānai-ʻeleu paʻa, kūpono ia no nā huila lima pahu waiuma ikaika.
(3) Kiʻekiʻe wela a me kiʻekiʻe puʻe kaiapuni
Kiʻekiʻe wela oxidation kala: Ma ka hoʻomalu 'ana i ka wela wela (200-300 degere), he Fe₃O₄ kiʻiʻoniʻoni papa hana ma luna o ka ilikai, a hiki i ke ana wela hiki i 500 degere. Hoʻohana pinepine ʻia no ka hoʻoponopono ʻana i nā mea hana paila.
Hoʻokumu ʻia ka pae nitriding plasma: ε-Fe₂-₃N i loko o ka lewa ammonia, hoʻonui ʻia ka paʻakikī o ka ʻili i HV1200, a ʻoi aku ka maikaʻi o ka pale ʻana i ka wela wela.
4. Nā hoʻolālā pale i nā kaiapuni corrosive
(1) ʻenehana hoʻoikaika kiʻiʻoniʻoni Passivation
ʻO Chromium-mea hana passivation manuahi: hoʻololi ka molybdate a me ka silane i ka chromate kuʻuna, ʻo ia hoʻi ka ʻoluʻolu o ke kaiapuni a ua like kona kūpaʻa ʻana. Ma hope o ka chromium -free passivated ka huila lima o kekahi mea moku, ua hala ia i ka ho'āʻo paʻakai 480-hola i loko o kahi kaiapuni kai hoʻohālike.
(2) Hoʻolālā uhi hana
ʻO ka ʻōnaehana hoʻoheheʻe gradient: ʻo ka papa lalo electroplated nickel (5 -} 10μm) hāʻawi i ka pale cathodic, ʻo ka papa waena PVD plated AlCrN (2-3μm) nā poloka corrosive media, a me ka ʻaoʻao waho i kāpī ʻia me ka polymer fluorinated (20-30μm) hiki ke hoʻomaʻemaʻe iā ia iho. ʻO kēia hoʻolālā e hiki ai i ka huila lima ke loaʻa ke ola lawelawe o 8 mau makahiki i loko o ke kaiapuni hydrogen sulfide o kahi refinery.
(3) Ka pale ʻana a me ka mālama ʻana i ka microbial corrosion
Hoʻokomo ʻia ʻo Ag-Cu: Hoʻokumu ʻia kahi ʻāpana metala antibacterial ma ka ʻili ma o ka ʻenehana hoʻokomo ʻana i ka ion no ka pale ʻana i ka hana o ka sulfate-reducing bacteria (SRB). Hōʻike nā hoʻokolohua e hoʻemi ʻia ka nui o ka corrosion o ka huila lima i mālama ʻia i ka wai kai bacteria e 76%.
5. Nā mea nui o ke koho kaʻina hana a me ka mana maikaʻi
(1) Matrix hoʻoholo koho
(2) Nā node hoʻomalu maikaʻi
Maʻemaʻe ma mua o ka hoʻomaʻemaʻe ʻana: Pono ka ʻili o ke koena o ka ʻili ma mua a i ʻole like me 5mg/m² (ISO 8502-3 standard).
ʻO ka mānoanoa kiʻiʻoniʻoni Passivation: ʻOi aku ka nui o ka hoʻāʻo XPS Cr/Fe ma mua a i ʻole like me 1.5 (ASTM A967).
Ka hoʻopili ʻana i ka uhi: hiki i ka hoʻāʻo ʻoki -cross cut a hiki i ka papa ISO 2409 Class 1.
6. Nā hihia noi ʻoihana a me nā hiʻohiʻona ʻano
(1) Nānā hihia maʻamau
Hohonu -hohonu pae lima huila lima: AlCrN/TiSiN multilayer PVD uhi hoʻohana 'ia, a ua hala 10 makahiki o ka hōʻoia lawelawe ma kahi kiʻekiʻe -kaiapuni ma ka hohonu o 1500 mika.
ʻO ka huila mana mana nuklea: Electrochemical polishing + molybdate passivation i hui pū ʻia, hoʻomaikaʻi ʻia ka pale ʻana o ka radiation oxidation e 60%.
(2) Ke au hoʻomohala ʻenehana
ʻO ka mālama ʻana i ka ʻili naʻauao: E hoʻonui i nā ʻāpana deposition PVD ma o AI algorithm e hoʻokō i ka hana kiʻiʻoniʻoni maʻamau.
ʻO ke kaʻina hana ʻōmaʻomaʻo: -wai a me ka ʻenehana plasma haʻahaʻa haʻahaʻa -e hoʻemi ana i ka ikehu a me ka pollution.
Hōʻuluʻulu manaʻo
ʻO ka hoʻomaʻamaʻa ʻana i ka ʻili o nā huila kila kila ma nā wahi ʻino a me ka corrosive pono e noʻonoʻo piha ʻia mai nā ʻano ʻekolu: ke ʻano waena, ka ukana mīkini, a me ke kumukūʻai o ke ola. I ka wā e hiki mai ana, me ka holomua o nā ʻenehana e like me ka nano-coatings a me ka bionic structures, e hoʻomohala ʻia ka mālama ʻana i ka ʻili i ke ala o ka hoʻohui ʻana a me ka hoʻololi ʻana i ke kaiapuni. I ke koho ʻana i kahi kaʻina hana, pono nā ʻenekinia e hāʻawi i ka mea nui i nā kūlana honua e like me ASTM a me ISO, a e hana i nā hoʻokolohua ʻelemakule wikiwiki e pili ana i nā kūlana hana maoli no ka loaʻa ʻana o ke kumu kūʻai maikaʻi loa-hopena kūpono.
