Zinc-Nickel vs Zinc Plating on Hydraulic Fittings: Kahi e hele ai ke kālā keu.

ʻElua kolamu i kēlā me kēia pepa manaʻo, a ʻoi aku ke kumu kūʻai o ke kolamu zinc-nickel. Eia ka pane pōkole mua: e uku no ka hoʻopaʻa ʻana i ka zinc-nickel ke ʻike kāu mau mea pono i ka wā, ka paʻakai a i ʻole ka holoi ʻana. E noho me ka hoʻoheheʻe zinc maʻamau ke noho lākou i loko o kahi ʻāpana mana paʻa. ʻAʻole pili ka hoʻoholo zinc-nickel vs zinc plating e pili ana i nā pae maikaʻi. Aia ma kahi o ʻelua laina papapalapala like ʻole, a ʻo ke kālā āu e hoʻolilo ai i ʻāina ma nā wahi like ʻole ma kēlā me kēia.

Ua uku mua ka ʻenekinia mālama e pani ana i nā mea hoʻopili i hoʻopaʻa ʻia i ka makahiki ʻelua i ke kumukūʻai o ka kuhi hewa ʻana. Hōʻike kēia ʻatikala i ka mea i hana maoli ʻia i loko o kēlā me kēia laina ma Ruihua Hardware, i ke ʻano o nā helu paʻakai, a ma kahi e loaʻa ai ka hoʻomaikaʻi.

ʻO ka pane pōkole: uku no ka Zinc-Nickel ma waho, e noho me ka Zinc i loko

ʻO ka zinc plating maʻamau me ka trivalent passivation ka koho kūpono no ka hapa nui o ka hana hydraulic i loko. ʻO nā hale kūʻai mīkini, nā mea kanu hoʻoheheʻe injection a me nā laina hana meaʻai e holo i nā kaiapuni maʻemaʻe. ʻAʻole ʻike ʻia ka ʻohu paʻakai i nā mea hoʻopili ma kahi pūʻolo mana paʻa. No kēlā mau kaapuni, aia ke kālā keu i ka kānana a me ke kaʻina hana torque, ʻaʻole i ka uhi.

Loaʻa iā Zinc-nickel kāna uku ma nā kūlana ʻehā. ʻO nā lako kelepona e ʻike i ka paʻakai alanui. Nā mea hoʻonoho kahakai a i ʻole ma waho. Nā mea kanu meaʻai e hoʻoheheʻe i nā mea hana i kēlā me kēia lā. A ʻo kēlā me kēia hoʻouna ʻana e hele i ka moana i loko o kahi pahu kila. Inā pulu ka mea kūpono no nā pule, ʻo ka zinc-nickel ka ʻāpana liʻiliʻi i kona ola.

ʻElua Laina, ʻElua Paʻakai: ʻO ka mea e holo maoli ai ka hale kūʻai Plating

Hoʻomaka like nā laina ʻelua. Hana ʻia nā ʻāpana kila kalapona C45, hoʻoheheʻe ʻia i loko o kahi ʻauʻau alkaline, a laila ʻohi ʻia i loko o ka waikawa e wehe i ka oxide. Holo nā ʻāpana pololei liʻiliʻi i nā barela. E kau ana nā kuʻekuʻe lima, nā kāʻei a me nā mea hoʻopaʻa puʻupuʻu ma luna o nā pā i hiki ke uhi pono i kēlā me kēia noho cone. Mai kēlā wahi, ʻokoʻa nā laina ʻelua.

Iloko o ka Laina Plating Zinc

Holo ka laina zinc i kahi ʻauʻau zinc alkaline, a laila kahi passivation chromium trivalent. ʻO ka mānoanoa waiho ʻāina ma kahi o 5 a 8 microns ma nā ʻāpana maʻamau. I loko o ke keʻena hoʻoheheʻe paʻakai ASTM B117, hoʻopaʻa maʻamau kēlā ʻōnaehana i ka ʻōpala keʻokeʻo no kahi o 96 mau hola. Hiki i ka ʻula ʻula ma mua o 240 mau hola. ʻO kēia kahi ʻōnaehana i hōʻoia ʻia, haʻahaʻa haʻahaʻa i pale i nā adapter hydraulic no nā makahiki he mau makahiki. Hōʻike ʻia kona mau palena e like me ka pauka keʻokeʻo a mohala ka ʻōpala ma hope o hoʻokahi a ʻelua paha hoʻoilo ma waho.

ʻO nā ʻāpana ma luna o 1000 MPa ikaika tensile, ʻoi aku ka nui o nā ferrules, e hele pū me ka bake hydrogen de-embrittlement ma kahi o 190 a 200 degere C. Pili kēlā ʻanuʻu ma nā laina ʻelua.

Iloko o ka Laina Zinc-Nickel

Hoʻokomo pū ka laina zinc-nickel i kahi huila o ka 12 a i ka 15 pakeneka nickel mai kahi ʻauʻau alkaline. Hoʻololi kēlā māhele nickel i nā mea a pau. ʻOi aku ka paʻa o ka uhi, ʻoi aku ka like o loko o nā milo, a ua hana ʻo ia i mea pale paʻa e pale aku i ka corrosion mai loko a waho. ʻO ka kikoʻī ma Ruihua Hardware he 8 a 12 microns o ka zinc-nickel, i hōʻoia ʻia ma 240 hola o ASTM B117 ma mua o ka ʻike ʻana o ka ʻulaʻula.

ʻOi aku ka maikaʻi o ka pāʻani me nā hoalauna. Noho ʻo Zinc-nickel ma kahi kokoke i ka alumini ma ka pālākiō galvanic, no laila e hoʻohaʻahaʻa liʻiliʻi i kahi e hoʻopili ai i nā kaula i loko o nā hale alumini a i ʻole nā ​​​​manu. ʻAʻole ia e ʻae i nā mahana lawelawe hoʻomau ma kahi o 120 degere C, kahi e hoʻohaʻahaʻa wikiwiki ai nā pani zinc maʻemaʻe.

He aha nā hola 240 o ka paʻakai e kūʻai maoli iā ʻoe

E noʻonoʻo i ke ʻano o ka helu. Holo ʻo ASTM B117 i ka noe sodium chloride 5 pakeneka ma 35 degere C, hoʻomau, ma kahi ʻāpana e kau ana. He mea hana hoʻohālikelike ia, ʻaʻole he kalena kahua-ola. ʻAʻole hiki ke ola i nā lā he 240 i waho o kahi mea i hala i 240 mau hola ma waho, no ka mea, ʻo ka abrasion, ka holoi holoi ʻana a me ka UV e hoʻohui i nā ala hoʻouka ʻaʻole ʻike ʻia e ka ʻaha Kuhina.

ʻO kēia ka mea a ka helu 240 hola e haʻi iā ʻoe. Ke noho ka pahu ukana o nā mea pono i loko o kahi paʻa haʻahaʻa no ʻeono pule, puka maʻemaʻe nā ʻāpana zinc-nickel a hiki i nā ʻāpana zinc-plated ke hōʻike i ka ʻele keʻokeʻo ma mua o ka hoʻokomo ʻana. Ke holoi ʻia ka mīkini mālama i ka mīkini i kēlā me kēia neʻe ʻana, mālama ka uhi ʻana i kona pale ma mua o ka pauka. Kūʻai ka helu iā ʻoe i ka palena, a ʻo ka margin ka mea e hoʻokaʻawale i kahi kūpono āu e pani ai i ka makahiki ʻeono mai kahi āu e pani ai i ka makahiki ʻelua.

Ke Kahea Pono ka Zinc Plating

Mai ʻae i ka mea kūʻai aku e kamaʻilio iā ʻoe i ka zinc-nickel no nā mea āpau. ʻO kēia nā hihia inā ʻo ka zinc plating ka kikoʻī pololei:

• Hoʻopaʻa ʻia nā mana ʻoihana i loko o ka hale, i loko o kahi mea kanu me ka holoi ʻole ʻana i kēlā me kēia lā.

• ʻO nā ʻāpana ʻokoʻa a me nā ʻāpana e noho ana i loko o kahi hale kūʻai maloʻo a hoʻohana ʻia i loko o nā mahina.

• ʻO nā rigs hoʻāʻo a me nā noho i haʻalele ʻole i ka hale hana.

• Kūkulu ʻia ka OEM kiʻekiʻe i kahi e kūʻai ʻia ai ka mīkini i kahi anuanu maloʻo a loaʻa i ka OEM ka ʻikepili kahua e hoʻihoʻi ai.

Ma kēlā mau ʻāpana, e hoʻolilo i ke kālā i mālama ʻia ma ka hui kūpono. ʻO kahi mea hoʻopili pololei JIC 2J i hoʻopaʻa ʻia i ka zinc i hoʻokomo ʻia me nā lola maʻemaʻe a me ka torque pololei e ʻoi aku ka lōʻihi o ka hoʻopili zinc-nickel i hoʻopaʻa ʻia i kea a waiho ʻia. ʻO ka uhi ʻana he mea hoʻololi, ʻaʻole ka pane holoʻokoʻa.

Ke uku ka Zinc-Nickel upgrade nona iho

I kēia manawa e hoʻohuli i ke kālā. E wehewehe i ka zinc-nickel inā ʻoiaʻiʻo kekahi o kēia mau mea:

• Hoʻohana ka mīkini i waho a puni ka makahiki, ʻoi aku ka paʻakai o nā alanui.

• Noho ka mea hoʻonoho i loko o kekahi mau kilomita mai kahakai.

• Holoi ka mea kanu i nā mea hana i kēlā me kēia lā a i ʻole holo i nā pōʻai hoʻomaʻemaʻe caustic.

• Hoʻouna ʻia nā ʻāpana ma ke kai a kali paha i loko o kahi pahu no nā pule ma mua o ke kau ʻana.

• ʻO nā kaula kūpono i ka alumini, a makemake ʻoe e hoʻolōʻihi i ka hoʻouka kaua galvanic.

No kēlā mau hana, he wahi kuhikuhi maikaʻi nā metric standpipe i ka moʻo 50011. Hoʻohui lākou i ka paipu kila i ka hose no DIN 2353 a me ISO 8434-1, i hana ʻia mai C45 kila me 8 a 12 microns o zinc-nickel, i loaʻa i ka moʻo māmā i ka 315 bar a me ka moʻo kaumaha i ka 630 bar. ʻO ka crane mobile a i ʻole ka mīkini awa ʻo ia ke kuleana i uhi ʻia no lākou.

Pehea ʻo Ruihua Hardware e hōʻailona ai a hoʻouna i nā laina ʻelua

Pono ʻoe e hōʻoia i ka uhi ʻana ma hope o ka hōʻea ʻana o nā ʻāpana, ʻaʻole hilinaʻi wale i ka ʻōlelo. Hōʻailona ʻo Ruihua Hardware i nā kikoʻī plating ma ka lepili pahu, a loaʻa nā palapala hōʻoia ma ke noi. Inā ʻike ʻia kahi kiʻi i ka zinc-nickel i 240 mau hola no ka ASTM B117, e hoʻololi ʻia kēlā callout i ke kauoha kūʻai a me ka palapala hōʻoia, no laila he mea kāu e nānā ai.

Hoʻokahi ʻōlelo aʻoaʻo: ʻano like nā ʻāpana o nā laina ʻelua ma waho o ka pahu. He kala kalakala ʻelua me ka passivation maopopo. Mai hilinai i ka hoao maka. E mālama i nā lepili me nā pahu, a i ʻole ka hoʻololi ʻana o ka mālama hou e hoʻohui i ka waihona i loko o hoʻokahi mahina.

Nīnau pinepine

ʻEhia ka nui o ke kumu kūʻai o ka zinc-nickel plating ma mua o ka zinc plating?

ʻElua a ʻekolu manawa ʻoi aku ka nui o ka paʻakai paʻakai no ka zinc-nickel, no ka mea, ʻoi aku ke kumukūʻai o ka paʻakai nickel a me ka ʻauʻau paʻa. He ʻāpana wale nō ka pāpaʻi ʻana o ke kumukūʻai ʻāpana i hoʻopau ʻia, akā naʻe, ma kahi mea hoʻopili C45 mīkini e neʻe pinepine ai ka ʻōlelo ma kahi pākēneka liʻiliʻi, ʻaʻole ka nui. E noi i nā koho ʻelua ma ka RFQ like a hoʻohālikelike i nā kumukūʻai ʻāpana i pau.

Hiki iaʻu ke hoʻohui i ka zinc-plated a me ka zinc-nickel fittings ma ka mīkini hoʻokahi?

ʻAe. ʻO nā mea ʻelua i hoʻolaʻa ʻia ma luna o ke kila C45 hoʻokahi, ʻaʻole lākou e hoʻokau i nā pilikia galvanic me kekahi. E hoʻopili i nā ʻāpana zinc-nickel kahi e hiki ai ka maʻu a me ka paʻakai i nā mea pono, a maikaʻi ke kau ʻana i ka zinc ma nā wahi ʻē aʻe ma ka kaapuni like.

ʻO 240 mau hola o ka paʻakai paʻakai, ʻo ia hoʻi, he 240 mau lā ma ke kula?

ʻAʻole. ʻO ASTM B117 kahi hoʻāʻo hoʻohālikelike hoʻohālikelike i loko o kahi 5 pākēneka o ka noe paʻakai ma 35 degere C, e holo mau ana. ʻO ke ola o ke kahua e pili ana i ka pinepine holoi, ka paʻakai alanui, ka abrasion a me ka mānoanoa o ka uhi ʻana, no laila ʻaʻole hiki ke hoʻololi ʻia nā hola 240 i loko o ke keʻena i nā mahina ma waho. Hōʻike ia iā ʻoe i ka hoʻohālikelike ʻana o kekahi uhi me kekahi ma lalo o ka hoʻomāinoino like.

ʻO wai nā mea pono e hele mai me ka zinc-nickel plating ma ke ʻano maʻamau?

Ma ka ʻaoʻao metric DIN 2353, hāʻawi ʻia nā moʻo e like me ka 50011 standpipe pololei me 8 a 12 microns o ka zinc-nickel, helu ʻia he 240 h i ka paʻakai paʻakai. ʻO nā mea hoʻololi JIC e like me ka moku pololei 2J me ka zinc plating ma ke ʻano maʻamau. Hiki ke kuhikuhi ʻia kēlā me kēia laina ma ka pae ʻōlelo, no laila e haʻi i ke kaiapuni ke noi ʻoe i ka ʻōlelo.

E kiʻi i kahi kikoʻī Plating ma kāu ʻōlelo aʻe

E haʻi mai iā mākou i kahi e noho ai nā lako a e haʻi mākou i ka uhi kūpono, ʻaʻole ka mea kūʻai nui loa. E nānā i ka laulā piha ma ka ʻaoʻao huahana , nānā i ka 50011 standpipe pololei kiko'ī  a i 'ole ka 2J pololei JIC adapter , a laila e hoʻouna i kāu RFQ ma o ka ʻaoʻao pili . Pane ʻo Ruihua Hardware me nā koho pani, nā kumukūʻai a me nā manawa alakaʻi i hoʻokahi lā hana.
