ʻO ka lāʻau lapaʻau ʻo Butterfly Valve Surface

Wahi a ka noiʻi ʻana a me ka nānā ʻana, ʻo ka corrosion kekahi o nā kumu nui e pōʻino ai nā kiwi lele.Ma muli o ka pili ʻana o ka lua o loko me ka mea waena, ua ʻino loa ia.Ma hope o ka corrosion, e liʻiliʻi ke anawaena o ka valve a piʻi ke kūpaʻa o ke kahe, e pili ana i ka hoʻouna ʻana o ka medium.Hoʻokomo ʻia ka ʻili o ke kino valve ma ka honua a ma lalo paha.Pili ka ili me ka ea a pulu ka ea, no laila hiki ke ʻā.Ua uhi paʻa ʻia ka noho valve ma kahi e pili ai ka lua o loko me ka mea waena.No laila, ʻo ka hoʻomaʻamaʻa ʻana i ka uhi ʻana o ke kino valve a me ka pā valve ʻo ia ke kumu kūʻai maikaʻi loa e pale aku ai i ka corrosion i loko o ke kaiapuni o waho.

 

1. ʻO ke kuleana o ka uhi ʻana i ka ʻili o ka valve lele

01. ʻIke mea kino kiwi

Hoʻohana ʻia ka waihoʻoluʻu o ka ʻili i nā ʻili i hana ʻole ʻia o ke kino valve a me ka pāpale.Ma o kēia hōʻailona kala, hiki iā mākou ke hoʻoholo koke i ka mea o ke kino valve a hoʻomaopopo maikaʻi i kona mau ʻano.

02. Ka hopena pale

Ma hope o ka uhi ʻia ʻana o ka ʻili o ke kino valve me ka pena, ua kaʻawale ka ʻili o ke kino valve mai ke kaiapuni.Hiki ke kapa ʻia kēia hopena pale he hopena pale.Eia naʻe, pono e kuhikuhi ʻia ʻaʻole hiki i kahi ʻāpana lahilahi o ka pena ke hāʻawi i kahi hopena pale.No ka mea, loaʻa i nā polymers kekahi degere o ka hanu ʻana, i ka wā ʻeleʻele loa ka uhi ʻana, ʻae nā pores i ka wai a me nā molekala oxygen e hele manuahi.He koʻikoʻi koʻikoʻi nā kiwi hoʻopaʻa haʻahaʻa i ka mānoanoa o ka uhi epoxy resin ma ka ʻili.I mea e hoʻomaikaʻi ai i ka impermeability o ka uhi, pono e hoʻohana i nā mea pale anti-corrosion i nā mea hana kiʻiʻoniʻoni me ka haʻahaʻa haʻahaʻa o ka ea a me nā mea hoʻopihapiha paʻa me nā waiwai pale kiʻekiʻe.I ka manawa like, pono e hoʻonui ʻia ka nui o nā ʻāpana o ka uhi ʻana i hiki i ka uhi ʻana i kahi mānoanoa a he ʻeleʻele a ʻaʻole porous.

 03. ʻAi ʻino

Hoʻopili nā ʻāpana o loko o ka pena me ka metala e hoʻoheheʻe i ka ʻili metala a i ʻole e hana i nā mea pale e hoʻomaikaʻi i ka hopena pale o ka uhi.No nā valve me nā koi kūikawā, pono ʻoe e hoʻolohe i ka haku mele e pale aku i nā hopena koʻikoʻi.Eia kekahi, hiki ke hana i nā pahu kila kila i hoʻohana ʻia i loko o nā paipu aila e like me nā mea hoʻokaʻawale corrosion ma muli o nā huahana degradation i hana ʻia ma lalo o ka hana a kekahi mau aila a me ka hana maloʻo o nā kopa metala.

04. Palekana electrochemical

Ke hoʻopili ʻia ka uhi hoʻoheheʻe dielectric me ka ʻili metala, e hana ʻia ka ʻino electrochemical ma lalo o ke kiʻiʻoniʻoni.Hoʻohana ʻia nā metala me ka ʻoihana kiʻekiʻe ma mua o ka hao ma ke ʻano he mea hoʻopiha i nā uhi, e like me ka zinc.E pāʻani ia i kahi hana palekana ma ke ʻano he anode mōhai, a ʻo nā huahana corrosion o ka zinc he zinc chloride i hoʻokumu ʻia i ka paʻakai a me ka zinc carbonate, ka mea e hoʻopiha ai i nā āpau i loko o ke kiʻiʻoniʻoni a hoʻopaʻa paʻa i ke kiʻiʻoniʻoni, e hōʻemi loa i ka corrosion a hoʻonui i ke ola lawelawe o ka pahu hopu.

2. Hoʻohana maʻamau ʻia nā uhi ma nā kiwi metala

ʻO ke ʻano o ka mālama ʻana i ka ʻili o nā kiwi ka mea nui i ka uhi pena, galvanizing a me ka uhi pauka.He pōkole ka manawa pale o ka pena a ʻaʻole hiki ke hoʻohana ʻia ma lalo o nā kūlana hana no ka manawa lōʻihi.Hoʻohana nui ʻia ke kaʻina hana galvanizing i nā pipelines.Hoʻohana ʻia nā galvanizing hot-dip a me electro-galvanizing.He paʻakikī ke kaʻina hana.Hoʻohana ka pretreatment i nā kaʻina pickling a me ka phosphating.Aia nā koena waikawa a me ka alkali ma ka ʻili o ka mea hana, e waiho ana i ka ʻino ʻO ka pilikia huna e maʻalahi ka hāʻule ʻana o ka papa galvanized.ʻO ke kūpaʻa corrosion o ke kila galvanized he 3 a 5 mau makahiki.ʻO ka pauka i hoʻohana ʻia i loko o kā mākou Zhongfa valves he mau hiʻohiʻona o ka uhi mānoanoa, ka pale ʻana i ka corrosion, erosion resistance, etc., hiki ke hoʻokō i nā koi o nā valves ma lalo o nā kūlana hoʻohana o ka ʻōnaehana wai.

01. ʻO ka uhi ʻana o ke kino epoxy resin

Loaʻa nā hiʻohiʻona penei:

· Ka pale ʻana i ka ʻino: ʻO nā kaola kila i uhi ʻia e ka epoxy resin-coated maikaʻi ke kūpaʻa ʻana, a ua hoʻemi nui ʻia ka ikaika o ka hoʻopaʻa ʻana me ke kaʻa.He kūpono lākou no nā kūlana ʻoihana i nā wahi haʻahaʻa a i ʻole ka media corrosive.

· Paʻa ikaika: ʻO ka loaʻa ʻana o nā pūʻulu hydroxyl polar a me nā paʻa etera i loaʻa i loko o ke kaulahao molekala resin epoxy e hoʻopili nui ʻia i nā mea like ʻole.ʻO ka emi ʻana o ka epoxy resin i ka wā e hoʻōla ʻia ai he haʻahaʻa, liʻiliʻi ke koʻikoʻi kūloko i hana ʻia, a ʻaʻole maʻalahi ka hāʻule a hāʻule ʻole o ka uhi pale.

· Nā waiwai uila: ʻO ka ʻōnaehana epoxy resin i hoʻōla ʻia he mea insulating maikaʻi loa me nā waiwai dielectric kiʻekiʻe, ke kū ʻana o ka leakage o ka ʻili, a me ke kūpaʻa arc.

· Kūleʻa ʻole: ʻO ka ʻōnaehana epoxy resin i hoʻōla ʻia ʻo ia ke kūpaʻa i ka hapa nui o nā mold a hiki ke hoʻohana ʻia i nā kūlana ʻino.

02. ʻO ka pā paʻi paʻi paʻi nilon mea

ʻAʻole hiki ke hoʻopōʻino ʻia nā lau nylon a ua hoʻohana maikaʻi ʻia i nā noi he nui e like me ka wai, ka lepo, ka meaʻai a me ka desalination wai kai.

· Ma waho o ka hana: Hiki i ka uhi uhi nylon ke hele i ka hoʻāʻo ʻana i ka paʻakai.ʻAʻole i ʻili ʻia ma hope o ka hoʻokomo ʻia ʻana i loko o ka wai kai no nā makahiki he 25, no laila ʻaʻohe ʻino i nā ʻāpana metala.

· Kūleʻa ʻaʻahu: maikaʻi loa ke kūpale ʻaʻahu.

· Ke kū'ē i ka hopena: ʻAʻohe hōʻailona o ka ʻili ʻana ma lalo o ka hopena ikaika.

 

3. Kaʻina hoʻopā

ʻO ke kaʻina hana hoʻopuʻu ʻo ia ka hana mua ʻana o ka mea hana → wehe i ka lepo → hoʻomaʻamaʻa → hoʻopuʻi (primer - trimming - topcoat) → paʻa → hoʻoluʻu.

Hoʻohana nui ʻia ʻo Spraying Spraying i ka pāpaʻi electrostatic.E like me ka nui o ka mea hana, hiki ke hoʻokaʻawale ʻia ka pulupulu electrostatic i ka pauka electrostatic spraying production line a me ka pauka electrostatic spraying unit.Ua like nā kaʻina hana ʻelua, a ʻo ka ʻokoʻa nui ke ʻano o ka huli ʻana o ka mea hana.Hoʻohana ka laina hana spray i ke kaulahao hoʻouna no ka hoʻouna ʻakomi, ʻoiai e hoʻokiʻekiʻe lima ʻia ka ʻāpana spray.Hoʻomaluʻia ka mānoanoa o ka uhi ma 250-300.Inā emi ka mānoanoa ma mua o 150 μm, e ho'ēmiʻia ka hana pale.Inā ʻoi aku ka mānoanoa ma mua o 500 μm, e emi ana ka hoʻopili ʻana o ka uhi, e emi ka hopena o ka hopena, a e hoʻonui ka pauka.
