Ka Papa Hana Hana: Nā Luʻi o ka ʻĀina Hana i nā huila lima lima
I loko o ka hana kemika, kahe pinepine nā kemika ʻinoʻino like ʻole, e like me ka chlorine a me ka soda caustic i loko o ka ʻoihana chlor{0}}alkali, a me nā sulfides i loko o ka hoʻomaʻemaʻe ʻaila, kahi e koi nui ai i ka pale ʻana o nā huila pahu pahu. Ma ke kahua o ka ʻenekinia moana, ʻo ke kiʻekiʻe-paʻakai a kiʻekiʻe-ka wai kai e hoʻopōʻino ʻia i nā huila metala, e hoʻemi ana i ka hana a i ʻole ka hāʻule ʻana o nā huila lima. Wahi a nā helu helu, ʻo nā hemahema o nā mea hana i hoʻokumu ʻia e ka corrosion o nā wili lima valve ke kumu o nā piliona kālā i nā poho waiwai i ka ʻoihana honua i kēlā me kēia makahiki.
Nā kumu kumu e pili ana i ka hana ʻana i ka ʻino-o nā huila paʻa paʻa
Nā hiʻohiʻona waiwai
ʻO ka mea waiwai ke kumu no ka hoʻoholo ʻana i ka hana anti-corrosion o nā huila lima. Ma waena o nā mea metala, he haʻahaʻa ke kumukūʻai ke kila kalapona akā maʻalahi loa ka ʻōpala. I loko o kahi kaiapuni haʻahaʻa, hiki i ka huila kalapona hao pale ʻole ke hōʻike i ka ʻōpala i loko o 1-2 mahina; ʻO ke kila kila maikaʻi ke kūpaʻa corrosion ma muli o ke kiʻi passivation i hana ʻia e nā mea chromium. Ma waena o lākou, ʻoi aku ka maikaʻi o 316 stainless steel ma mua o 304 stainless steel i loko o kahi kaona chloride ma muli o ka hoʻohui ʻana o nā mea molybdenum. ʻO nā mea metala ʻole e like me ka polytetrafluoroethylene (PTFE) he paʻa kemika ikaika loa a hiki ke kū i nā waikawa ikaika a me nā alkalis, akā haʻahaʻa ko lākou ikaika mechanical. ,
Nā kumu kaiapuni
He hopena koʻikoʻi ko ke kūlana kaiapuni i ka hana anti-corrosion. Ma ke ʻano o ka haʻahaʻa, ke ʻoi aku ka haʻahaʻa pili ma mua o 60%, e piʻi ka pōʻino o nā huila lima metala i 3 -5 manawa. I loko o nā pāpaʻi kemika, nā ʻakika oxidizing ikaika (e like me ka sulfuric acid concentrated), nā alkali ikaika (e like me ka sodium hydroxide solution) a me nā ʻoluʻolu paʻakai e ʻino pono i ka ʻili o ka huila lima. E pili pū ana nā hoʻololi wela i ka hana anti-corrosion. ʻO ka wela kiʻekiʻe e hoʻolalelale i nā hopena kemika. ʻO ke koʻikoʻi wela i hoʻoulu ʻia e ka loli ʻana o ka mahana e hiki ke hana i nā microcracks ma ka ʻili o ka huila lima, e hāʻawi ana i kahi ala no ka ʻino.
Kaʻina hana hana
Hoʻopili pololei ke kaʻina hana lapaʻau ʻili i ka hiki ke kū i ka ʻino -o ka huila lima. Hoʻokumu ke kaʻina hana electroplating i kahi pale pale ma ka ʻili ma o ka chrome plating, zinc plating, etc.; hoʻohana ke kaʻina hana i ka epoxy resin, polyurethane a me nā mea ʻē aʻe e hoʻokaʻawale i nā media corrosive; Hiki i ka ʻenehana puhi wela ke hana i nā uhi -kiʻekiʻe e like me nā seramika ma ka ʻili metala, e hoʻomaikaʻi nui ana i ka hana anti-corrosion.
Ka hoʻohālikelike a me ka nānā ʻana o ka hana kūʻē -corrosion o nā huila lima i hana ʻia me nā mea like ʻole.

Nā ʻenehana a me nā kaʻina hana Frontier no ka hoʻomaikaʻi ʻana i -hana kūʻē i ka corrosion
I nā makahiki i hala iho nei, ke ʻimi mau nei ka ʻoihana i nā ʻenehana anti-corrosion hou. Hoʻomaikaʻi nui ʻia ka ʻenehana uhi Nano -no ke kū ʻana i ka ʻino ma o ka hana ʻana i kahi kiʻiʻoniʻoni pale nano{3}}level ma ka ʻili; hoʻohana ʻia ka ʻenehana hoʻopaʻa ʻana iā ia iho-hoʻohana i ka ʻenehana microcapsule e hoʻokuʻu i nā mea hoʻoponopono i ka wā e poino ai ka uhi e hoʻoponopono ʻakomi i ka wahi i poino; hoʻohui ʻia ka ʻenehana mea hoʻohuihui i ka ikaika kiʻekiʻe o ka metala me ke kūpaʻa ʻino o ka mea ʻole-metala e hana i nā huahana huila lima me ka hana ʻoi aku ka maikaʻi.
Hōʻike i ka ʻikepili hoʻāʻo maoli a me nā haʻawina hihia e pili ana i ka hana anti-corrosion
Ua hoʻokomo kekahi hui kemika i ke kila kalapona, 304 kila kuhiliʻole, a me 316 mau huila kila kila ma nā kiwi o ka paipu ʻakika sulfuric. Ma hope o 6 mau mahina o ka hana ʻana, ua ʻino ka huila kalapona kila a hiki i ka hohonu o ka corrosion i 0.3mm; ua hōʻike ʻia ka wili liʻiliʻi 304 stainless steel a ʻo ka hohonu o ka corrosion he 0.05mm; ʻaʻohe hoʻololi ʻike maopopo ʻia ka huila lima kila 316. Hōʻike pololei kēia hihia i nā ʻokoʻa hana o nā huila lima i hana ʻia i nā mea like ʻole i loko o kahi ʻano corrosive.
Nā Kauhana Hoʻomohala ʻOihana: Nā kuhikuhi hou no ka -ʻenehana anti-corrosion i ka wā e hiki mai ana
I ka wā e hiki mai ana, me ka hoʻomohala ʻana o ka ʻike ʻenehana, e hui pū ʻia nā ʻōnaehana naʻauao a me nā ʻōnaehana hoʻolaha mua me ka ʻenehana anti-corrosion lima e nānā i ke kūlana corrosion o nā huila lima i ka manawa maoli. I ka manawa like, e hoʻololi mālie nā mea ʻenehana anti-corrosion e pili ana i ke kaiapuni i nā ʻenehana haumia kiʻekiʻe -e hoʻokō i nā pono o ka hoʻomohala hoʻomau. Eia hou, e hoʻohana pū ʻia nā loina bionic i ka hoʻolālā anti-corrosion, e hoʻohālike ana i ka corrosion-kūkulu olaola i loko o ke ʻano a me ka hoʻomohala ʻana i nā mea anti-corrosion hou.
Panina: He Pōhaku Koʻikoʻi o ka Palekana ʻOihana
Ka hana anti-corrosion oHuila lima paaʻo ia ke kī e hōʻoia i ka hana paʻa o nā mea hana ʻoihana, hoʻemi i nā kumukūʻai mālama, a pale aku i nā pōʻino palekana. Ma ka hoʻomau ʻana i ka koho ʻana i nā mea waiwai, ka hoʻomaikaʻi ʻana i nā kaʻina hana, a me ka hoʻomohala ʻana i ka ʻenehana anti-corrosion, e hoʻomau ka ʻoihana i ka hoʻomaikaʻi ʻana i ka hana anti-corrosion o nā huila lima a kūkulu i kahi laina palekana paʻa no ka hoʻomohala ʻana i nā ʻoihana. I ka wā e hiki mai ana, me ka holomua o ka ʻenehana, ua manaʻo ʻia ka hana anti-corrosion o nā huila paʻa valve paʻa e hoʻokō i nā holomua hou a lawelawe maikaʻi i nā ʻano ʻoihana like ʻole.
