2. Ho'āʻo i ka corrosion kū'ē o Valve Hand Wheels mea i loko o ka 'oihana like 'ole

1. ʻOihana Kimia

ʻO ka ʻoihana kemika e pili ana i nā mea hoʻolaha kemika nui loa, e like me nā waikawa ikaika e like me sulfuric acid, hydrochloric acid, a me nitric acid, alkali ikaika e like me ka sodium hydroxide, a me nā ʻano paʻakai like ʻole. I loko o ia ʻano, ʻoi loa ke kiʻekiʻe o ke kūpaʻa corrosion o ka mea huila lima valve. No ka laʻana, i loko o ka hale hana hana sulfuric acid, pono e wehe a pani pinepine ʻia ka valve e hoʻomalu i ke kahe o ka sulfuric acid. Inā hoʻohana ʻia ka huila lima lima kalapona, e ʻino koke ʻia e ka sulfuric acid, a hiki ʻole ke hana maʻamau. I kēia manawa, hoʻohana ʻia ke kila kila kila kiʻekiʻe (e like me ke kila kuhiliʻole i loaʻa ka chromium kiʻekiʻe a me ka nickel kiʻekiʻe) a i ʻole -mea i mālama ʻia i ka corrosion no ka hana ʻana i nā huila lima e hoʻokō i nā pono o ka -hoʻohana lōʻihi. Wahi a nā ʻikepili pili, ma ka ʻoihana kemika, ʻo ke kumu kūʻai o ka hoʻoponopono ʻana a i ʻole ka hoʻololi ʻana ma muli o ka lawa ʻole o ka pale ʻana i ka corrosion o nā mea waiwai he 30% - 40% o ka nui o ke kumukūʻai mālama pono. ,

2. ʻOihana kai

Hōʻike ʻia ke kaiapuni moana e ka paʻakai kiʻekiʻe, ka haʻahaʻa kiʻekiʻe, a me ka ʻinoʻino o ke kai. Ma luna o nā moku, pono e hoʻohana pinepine ʻia ka ʻōnaehana valve no ka mālama ʻana i ke kahe a me ka puka ʻana o ke kai, ka hoʻoponopono ʻana i ka wai ballast, a me nā mea ʻē aʻe. No ka la'ana, ma luna o kekahi moku li'ili'i 'a'ole i ho'ohana 'ia nā mea 'ino'ino kūpono, 'o ka Valve Hand Wheels he mau lua poino ko'iko'i ma ka ili ma hope o ka hapalua makahiki o ka ho'ohana 'ana, a he mea pa'akikī loa ka hana. Eia nō naʻe, hiki ke hoʻohana paʻa ʻia nā huila lima i hana ʻia me ke keleawe a i ʻole 316 stainless steel i loko o ke kai moana no kekahi mau makahiki, e hoʻomaikaʻi nui i ka hilinaʻi a me ke ola lawelawe o ka ʻōnaehana valve o ka moku. I loko o nā hale nui e like me nā kahua o waho, ʻoi aku ka paʻakikī o nā koi kūpaʻa corrosion no nā mea hana lima lima valve. Ma waho a'e o ka ho'ohana 'ana i -ki'eki'e ki'eki'e ka 'ino'ino-mea metala kū'oko'a, ua hana pū 'ia nā lā'au lapa'au anti-corrosion no ka ho'opa'a 'ana i ka hana pa'a no ka wā lō'ihi ma nā kaiapuni kai ko'iko'i. ,

3. ʻOihana meaʻai a mea inu

ʻO ka ʻoihana meaʻai a me nā mea inu he mau koi kiʻekiʻe loa no ka maʻemaʻe, a e hoʻopili pū kekahi mau kaʻina hana me kekahi mau media corrosive, e like me nā mea inu acidic, detergents, etc.Huila lima lima puka pukaʻAʻole pono e loaʻa i ke kūpaʻa corrosion maikaʻi wale nō, akā e hoʻokō pū kekahi i ka hoʻomaʻemaʻe meaʻai a me nā kūlana palekana. ʻO nā mea palaki (e like me PP, PE, a me nā mea'ē aʻe e kūpono ana i nā kūlana meaʻai) a me nā mea kila kila i hoʻohana nuiʻia i kēiaʻoihana. Hiki i nā mea palaki ke pale pono i ka ʻino mai nā mea inu ʻawaʻawa a ʻaʻole hiki ke ulu i ka maʻi bacteria; ʻO nā mea kila kila maikaʻi ke kūpaʻa a me ka maʻemaʻe, a maʻalahi ka ʻili a maʻalahi hoʻi e hoʻomaʻemaʻe.

3. Nā ʻano hoʻāʻo a me ka hoʻohālikelike ʻikepili o ka pale ʻana i ka corrosion

● ho'āʻo paʻakai paʻakai

ʻO ka hoʻāʻo ʻana i ka paʻakai he ʻano hana maʻamau e hoʻāʻo ai i ka pale ʻana i ka corrosion o nā mea. Ma kahi mahana (maʻa mau 35 degere ), ka haʻahaʻa pili (ma kahi o 95%), a me ka neʻe ʻana o ka paʻakai paʻakai (ʻoi aku ka nui o NaCl), loiloi ʻia ka mea hoʻāʻo e loaʻa ai kona kūpaʻa paʻakai paʻakai. ʻO kēia ka hoʻohālikelike o kekahi mau ʻikepili mai nā hoʻāʻo ʻana i ka paʻakai ma luna o kekahi mau mea maʻamau ʻo Valve Hand Wheels

Hōʻike ka ʻikepili i loko o ka hoʻāʻo ʻana i ka paʻakai paʻakai, ʻokoʻa ka pale ʻana o ka corrosion o nā mea like ʻole. ʻOi aku ka maikaʻi o ke kūʻē ʻana i ka corrosion, a hiki ke ʻino nui i ka manawa pōkole; 304 kuhiliʻole kila a me ke keleawe i kekahi corrosion kū'ē, akā, hoʻohālikelike me 316 kuhiliʻole kila a me polypropylene (PP), ko lakou corrosion kū'ē i kekahi mamao; Hōʻike ka 316 kila kila a me ka polypropylene (PP) i ke kūpaʻa maikaʻi ʻana i ka ʻinoʻino paʻakai, ʻoi aku ka polypropylene (PP), ʻaneʻane ʻaʻohe loli i ka hoʻāʻo ʻana i ka paʻakai paʻakai lōʻihi. ,

● ʻO ka hoʻāʻo ʻana i ka hoʻāʻo ʻana i ke kaiapuni ʻokoʻa

I mea e hoʻohālikelike maoli i ka media kemika kēlāHuila lima ma ka pahu paniʻike ʻia i loko o nā ʻenehana ʻoihana like ʻole, ke hoʻokō ʻia nei nā hoʻokolohua kaiapuni medium. Ua koho ʻia kekahi mau mea hoʻolaha kemika maʻamau, e like me 5% sulfuric acid solution, 10% sodium hydroxide solution, 3% sodium chloride solution, a me nā mea ʻē aʻe. ʻO kēia ka hana o kekahi mau mea ma hope o ka hoʻokomo ʻia ʻana i loko o nā pāpaʻi kemika like ʻole no kekahi manawa.

Hōʻike ka ʻikepili i ka hoʻāʻo ʻana i ka hoʻāʻo ʻana i loko o nā pāpaʻi kemika like ʻole, ua hōʻike mau ʻia ka 316 stainless steel a me ka polypropylene (PP) i ke kūpaʻa maikaʻi ʻana, a ʻaʻohe mea ʻike ʻino ʻia i nā ʻano mea hoʻoheheʻe kemika . 304 stainless steel i loaʻa kekahi corrosion i loko o ka sulfuric acid solution a me ka sodium chloride solution, akā ua ʻoi aku ka māmā o ke degere o ka corrosion ma mua o ke kila kalapona a me ke keleawe. Ua hōʻike ʻia ke kila kalapona i ka ʻino nui i loko o nā pāpaʻi kemika ʻekolu, e hōʻike ana ʻaʻole kūpono ia ma ke ʻano he mea no nā huila lima valve i loko o kahi kaiapuni kemika corrosive.

4. Nā hana e hoʻomaikaʻi ai i ka pale ʻana i ka corrosion o nā mea ʻo Valve Hand Wheels

1. ʻO ka koho ʻana i nā mea waiwai

Wahi a nā ʻano hoʻohana like ʻole a me nā hiʻohiʻona media, ʻo ke kī i ka hoʻomaikaʻi ʻana i ka pale ʻana i ka corrosion o nā huila lima valve ke koho kūpono i nā mea o nā huila lima valve. Ma nā wahi ʻino loa, ʻoi aku ka maikaʻi o nā mea me ka pale ʻana i ka corrosion ikaika. No ka laʻana, i loko o ka ʻakika ikaika a me ka alkali o ka ʻoihana kemika, koho ʻia ke kila kila kiʻekiʻe a i ʻole nā ​​​​mea hoʻohui kūikawā; i loko o nā kai moana, hoʻohana ʻia ka 316 stainless steel, keleawe a me nā mea ʻē aʻe i kū i ka ʻino wai kai; i loko o ka ʻoihana meaʻai a me nā mea inu, koho ʻia nā mea plastik a i ʻole ke kila kila e kū pono ana i nā kūlana hoʻomaʻemaʻe meaʻai a loaʻa ke kūpaʻa corrosion. ,

2. Hoʻohana i ka ʻenehana lapaʻau ʻili

Lapaʻau ʻana: ʻO ka uhi ʻana i ka ʻili o nā huila lima valve kahi ala maʻamau e hoʻomaikaʻi ai i ka pale ʻana i ka corrosion. No ka la'ana, hiki i ka -pani galvanizing wela ke hana i papa zinc ma ka ili o na huila lima hao kalapona, e ho'oka'awale maika'i i ka ea a me ka wai a me ka ho'omaika'i 'ana i kona kūpa'a 'ino. Hoʻohana nui ʻia ka uhi hao hao wela -ma kekahiHuila lima paahoʻohana ʻia ma waho, hiki ke hoʻonui i ke ola lawelawe o nā huila lima e 2-3 mau manawa. Eia kekahi, aia nā epoxy coatings, polyurethane coatings, etc. ʻO kēia mau uhi he adhesion maikaʻi a me ke kūpaʻa kino kino, hiki ke hāʻawi i ka pale hou no nā huila lima.​

Electroplating: He ʻenehana lapaʻau maʻamau i hoʻohana ʻia ʻo Electroplating. Ma o ka electroplating, hiki ke hoʻopaʻa ʻia kahi papa metala me ke kūpaʻa corrosion maikaʻi, e like me ka chrome plating, nickel plating, etc., ma ka ʻili metala. Loaʻa i ka papa chrome plating nā mea maikaʻi o ka paʻakikī kiʻekiʻe, ke kūpaʻa maikaʻi a me ka pale ʻana i ka corrosion ikaika, hiki ke hoʻomaikaʻi nui i ka maikaʻi o ka hiʻohiʻona a me ke kūpaʻa corrosion o ka huila lima. I kekahi mau manawa e kiʻekiʻe ai nā koi o ka hiʻohiʻona a koi ʻia kahi pae o ka pale ʻana i ka ʻino, ua hoʻohana nui ʻia nā huila lima valve chrome. ,

3. Ka mālama mau a me ka mālama ʻana

ʻO ka mālama mau ʻana a me ka mālama ʻana i nā huila lima valve hiki ke ʻike a hoʻoponopono i nā pilikia corrosion a hoʻonui i ko lākou ola lawelawe. No ka la'ana, e ho'oma'ema'e mau i ka huila lima no ka wehe 'ana i ka lepo, ka lepo a me nā mea ho'ohehe'e e pili ana i ka ili; e nānā inā aia nā hōʻailona o ka ʻino ma ka ʻili o ka huila lima. Ke ʻike ʻia ka ʻino liʻiliʻi, e hoʻoponopono i ka manawa, e like me ke kāʻei ʻana me ka pepa ʻili a laila - uhi hou iā ia. I loko o kekahi mau hale hana nui, e hoʻolālā ʻia kahi hoʻolālā mālama valve kikoʻī, a aia nō hoʻi nā lula a me nā kaʻina hana no ka mālama ʻana i ka huila lima e hōʻoia i ka hana paʻa o ka ʻōnaehana valve.

5. Ka hopena

ʻO ka pale ʻana o ka corrosion oNā huila lima limapili nā mea i kā lākou hopena noi ma nā ʻoihana like ʻole. Ma o ke kālailai ʻana i ke kūʻē ʻino o nā metala maʻamau a me-mea hao ʻole a me nā hoʻāʻo kaiapuni o nā ʻoihana like ʻole, hiki ke ʻike ʻia ʻo ke koho ʻana i nā mea kūpono, ka hoʻohana ʻana i ka ʻenehana lapaʻau maikaʻi, a me ka mālama mau ʻana ke kī i ka hoʻomaikaʻi ʻana i ko lākou pale ʻana.
