Electroplating metala galvanizing: enehana, lako a

Galvanizing - pono a me ka inexpensive, a nolaila, he hana maʻamau ma o ferrous i eliiaʻi no ka pale 'mai ka popopo. Ma ka hapanui o na hihia, ka mea, ua hoʻohana 'ia i loko o ka hana o ka lako a me fasteners, a me ke kila hei.

Nā Papahana O Ka ana i ka kiniki ka penaʻana

Anticorrosive galvanizing hula i loko o kekahi mau aoao, a me ka hana ke ola o ka ka penaʻana hilinaʻi nui ma luna o ka mānoanoa o ka aiiay, ahu iho.

A hana no ka penaʻana hilinaʻi nui ma luna o ka makemake ka waiwai, i ka huina hoonui nui, ano no kona hou ana.

I ka loa a me ka poe noonoo ole manufacturable, akā, ua hoakaka lawa ole ia'ku ia me mechanical stress o ka aiiay, ahu iho, - he anu galvanizing Via ka lepo, a iloko ona i kakauia he nui helu o finely puunaueia kiniki ka pauka.

By ka leo galvanizing? Iecaianoaaiiuo na lalani lua o ka wela-e hou iho i galvanizing. Ke ka penaʻana i loaa i loko o keia ano, high quality, a mau nō, akā, environmentally unsafe, no ka ua hoʻohana 'kiniki heheʻe, akā nō, e malama i kona wela iki emi o 500 ° C pono he nui nui o ka uila mana, Nine Inch ki ina hana like o ka' ilikai hoomalolo.

Mea i like loa me ka wela-e hou iho i galvanizing houʻanoʻenehana, akā, emi efficient hana o ana i ka aiiay ahu iho la ka ka thermal maholahune. Ua Ua hoʻohana 'ia ka wā i kiʻekiʻe e koi i ka mānoanoa, a me ka mawaho ka penaʻana naau.

Kekahi aoao o ka galvanizing - he kinoea-thermalʻawa, a ua hoʻohana 'ia no ka hoomalu ana i nui huahana a me nā hale i mea wale ole, e kau mai i ka auau.

Galvanizing i nele i na mea he nui o na keakea o 'ē aʻe ka penaʻana ki ina hana like, a i kona maikaʻiʻaoʻao.

Nā pono o galvanizing

A hana o ana i ka kiniki ka penaʻana ma ka electrolysis ka loa, he pono ole.

I ka papa kuhikuhiE pono, no ka i mea, ua galvanically pili metala galvanizing, o ka mea kiʻekiʻe degere o ka palekana i ka ka popopo i ka ili o ka mea. A lahilahi ahu iho la ka kiniki maoli ka hana ola o nā huahana he mau manawa, a no ia mea, ho'ēmi i kā ka lilo o ka malama a me ka hope.

Na ka penaʻana Ua loaa a hiki ole streaks a me droplets hoopaa iho la i ke kinona a me ka nui o nā huahana. Pili ia mea hiki i ka mea o kekahi, a hiki i ka loa luna 'kinona.

Malimali a me ka lā'ī Nani Loa ka paleʻana mai e koi i loko o ka hapanui o na hihia hou lapaau.

A he, o ka galvanizing kaʻina koi wale nīnūnē lilo, a me ka galvanic 'Ohi i ke kiʻekiʻe productivity.

keakea galvanizing

A hana no ana i aiiay ka penaʻana ma ka electrolysis mea,ʻaʻole me ka drawbacks.

Na ka papa kuhikuhiE drawback - haʻahaʻa kiniki mea pīlali i ka mea hiki ke hooheheeia, ma muli o ia i ka ili o ka huina hoonui pono e ho'ōla loa ua holoiʻia.

Ke downside Ua hoi ka ho okumu i loko o ka ka penaʻana kaʻinaʻawahia neoneo e noi ana mea, i ka hoʻomaʻemaʻe.

'Ole' ole hiki i hoopiha mai ana i ka makua metala me ka hydrogen, i nā hualoaʻa ma ka fragility o ka huina hoonui a me ka hoʻohuikau o ka ka penaʻana e like ai.

rula o ka hana

Galvanizing ua nānā 'ana ma luna o ka loina o ka aiiay hookoia, a me ka nānā' ana i ka unuhi i loko o electrochemical Loaʻaʻia o ka kiniki a me ka hao. Like kiniki i kekahi malalo electrochemical Loaʻaʻia, ka mea, ua kapa komo iā ia me ka sacrificial hoomalu i ferrous ke hooheheeia. I ua me kēia nui ka mea, ua loaʻa i loko o ka hua 'ia o electrochemical ka popopo.

Ma ka'okesaside o ka hao oxides i hana me ka mea i oi aku ka leo ma mua o ka mua metala. Ke'okesaside ho film i moe kolohe, a hele ia,ʻaʻole i oxidized metala ka oxygen. A me kiniki i loko o ka'okesaside ho film ua hana lahilahi, a olelo hoopomaikai, ka mea 'aʻole e hele i loko o ka'ōlinolino i oxygen hoʻomalu ole wale i ka ka penaʻana akā, i ka waihona ipu metala ma lalo iho.

Kind o galvanizing

Galvanizing plating - enehana, no ko ka i ka electrolysis, oa electrochemical redox keʻano o ka hanaʻana i loko o ka electrolyte ma lalo o ka aoao o ka ikaika uilaʻikena ...

Ma o ka haku mele 'ana o ka electrolyte kiniki plating ua maheleia i ekolu hoailona ia mea:ʻakika, mekala' åkilikai a me ka cyanide.

Ka loa mau hoʻohana hana o ana i ka kiniki ka penaʻana i weaklyʻakika electrolytes, pakahi aku la ia i ka hao a me ke kila māhele o ka luna 'hoʻonohonohoʻia. Products i ka kalapona a me ka oka a steels me ke kiniki ka penaʻana paku ole ia i emi hanana o ka hydrogen embrittlement, a ua loaa maikaʻi ke nānā aku, me ka maikai Nani Loa kanawai ma ka laulā huahelu o kikokiko.

Additional hoomalu no ka galvanizing

Ke aiiay hana o ke kiniki ka penaʻana hilinaʻi nui ma luna o kona mānoanoa, a ma ka galvanic palapala moʻopane o 5 microns, a me ke ano o ka electrolyte.

Ma kekahi mau hihia, o ka aiiay waiwai o ke kiniki ka penaʻana maoli he passivation, phosphating a pena.

Passivation (chromating) - Nine Inch hana maikaʻiʻole o nā huahana ma pāʻoihana o chromicʻakika paha paʻakai a pau, e like me ka hopena o i kaʻilikai i hana chromate Auana. Kēia kaʻina ole wale maoli ka aiiay waiwai o na mea he nui breeds, no ka mea, e like me ka hopena o ka hoʻokāʻoi 'gloss ka penaʻana, a me ka mea hiki ke pena i loko o nā waihoʻoluʻu.

I ka phosphating (lapaʻau me phosphoricʻakika i ka paʻakai) galvanized huahana ma ka posapahate ho film i hanaʻili. Ma hope o phosphating hiki nō pili HW.

kahua o ka hoʻonaʻauao galvanizing

? Iecaianoaaiiuo electroplating galvanizing ninoieo a mau keʻano o ka hanaʻana, kela mea keia mea o ka i ua 'ōlelo ma ka holoi ana i ka wai kahe pahu a me kaʻauʻau palaki a me ka hana.

First huahana i ke akahele ua holoiʻia o ka lepo, me ka unahiʻole,ʻanoʻenehana lubricant, coolant a HW residues a degreased i ka mekala 'åkilikai pāʻoihana. A laila, i ka electrolytic degreasing.

Mahope etched i loko o ka koʻana koko pāʻoihana o hydrochloricʻakika ma i ka ili hope loa ua ua holoiʻia me ka hōʻoni i kaʻilikai, a pickling ia ia lŘlŘ - ho'ā hope ma mua o ke noi ana o ka kiniki ka penaʻana. Wale laila paka lākou iho galvanizing.

Ma hope iho o ia, ina pono, a me ka möakäka hou maloko huahana o ka'okesaside ho film i loko o ka koʻana koko nitricʻakika pāʻoihana, a laila phosphating, passivation a me ka maloʻoʻana.

Additional hana hiki ke hana me ka galvanizing nā huahana. No ka laʻana, ka mea e hoomaemae ia ua unwound mua galvanizing, welded welau, nuiʻana ma hope o ka hamoia i a me kaʻeha.

Lako a pan no ka galvanizing

Uila laina - he mau 'kaʻina o ke kaʻina bato, a holoiʻia ia i loko o i mea mono- paha multilayer kiniki ka penaʻana me ka makemake iaea ooieoeiiaeuiiai waiwai.

I kulike ai me ka? Iecaianoaaiiie ka leo ipu hoʻohana me ka loli iki ana degere o ka mechanization. Nui hana ana ua hookupaa mechanized laina me ka 'akomi e hooponopono. Aia mau laina me ka hapa 'a piha manuale e hooponopono e like me ka ieie-laina.

Galvanizing laina ninoieo ole wale no na bato ke komo iloko. Ua nā amo nenoai o likeʻole manao, i ka pono lako a pan no ka wastewater lapaʻau, kākoʻo pono, i nā mea no ka galvanizing, paio hahana maoli nō hehee wale, wela poe kuai moni, ai ka cathode a me ka anode koʻokoʻo.

Ka mea kalaima nā hoʻokomo ea nenoai, ka maloʻoʻana cabinets a me refrigeration pono, Kānana pono, e loaa ana lako a demivody EII ni.

Electrolytes no ka galvanizing

No ka galvanizing, ke kaumaha ma muli o ka manao o ka huahana ua hoʻohana 'ia electrolytes, a i mahele ia i loko o ka papa kuhikuhiE pūʻulu elua.

Electrolytes ma i kiniki mea ma ka palapala o ka poe noonoo ole hydrated Ion, hea aku i ka meaʻakika. Kēia fluoboric, sulufahate a me ka koloriside pāʻoihana.

Eiiieaena noniakahiʻakika a'ākilikai electrolytes pihaʻi me kiniki Ion i loko o ka luna 'me ka maikaʻi a me ka io kauoha. Kēia ammine, pyrophosphate, cyanide a me nā pāʻoihana.

Ma i ka electrolyte ua noi ia, ka mea hilinaʻi nui kuhikuhi ma ka palapala moʻopane ana, a laila, i ka mea e like ai o ka hoʻokomo kālā o kiniki ma luna o ka 'atikala (ka cathode).

Mai eiiieaena electrolytes kiniki waihoia ma ka cathode ma kiʻekiʻe lakou hoopuehu ana o Ion. Me ka hoʻouluʻikena nuʻa metala emi hua a me maoli i ka hua o ka hydrogen.

No ia mea, galvanizing ma luna 'electrolytes hana ma haʻahaʻaʻikena nuʻa, a me ka penaʻana o ke kiʻekiʻe loa quality, maikai na hua liilii a me homogeneous.

Ma weaklyʻakika electrolytes alodio galvanic kiniki, ma ka home a me, hele ma kiʻekiʻe he paʻapū, me ka oi aku ma mua o ka wā hoʻohana luna 'pāʻoihana kōmi. Ano o nā huahana loaa ka maikai, aka, me ka ka penaʻana mea e kiʻekiʻe loa ka pono a me ka mea pono kŘpa mea huahana kinona wale no.

galvanizing

ʻanoʻenehana kaʻina ia lŘlŘ 'ana i loko o ka galvanizing bata o ka electrolyte. Ua hōʻike pū 'ana mai o kaʻeleʻele metala huahana, a ua hanaiia ma kūikawā nā uila aʻa lolo he uila pono (ka cathode), a me ka maʻemaʻe kiniki paha i loko o ka palapala o ka papa o nā waihoʻoluʻu piha i loko o kūikawā hei pauku (anode).

Iloko o ka electrochemical naoh ma lalo o ka aoao o ka uilaʻikena nuʻa 1 i 5 A / dm kiniki mea hoʻoheheʻe i loko o ka electrolyte, a laila, e waihoia kona Ion ma ka cathode e hana i kekahi plating mānoanoa o 4-25 microns.

Oia hoi, ka hoʻohana 'ana i kēiaʻano hana ua loaa fasteners (hoʻopaʻa i a me ka hua pisetakia,) me kaʻaʻahu a me ka lā'ī ka penaʻana.

Hana nona iho laina no ka galvanizing

Hoikehonua, galvanizing laina - mea he maopopo hana nona iho laina, i hanaʻia a pau na kapuwai o ka penaʻana, me kuʻihao a me degreasing o kona mea e like me nā huahana o kekahi mau hana a me ka hoʻonohonohoʻia.

Akomi laina nui oia i ka lākou o nāʻanoʻenehana plating bato, māhele rectifiers, hoʻouka / unloading nā hale lālā lāʻau, amo pono, pono no ka hoʻokomo ea, ka wai lako a me ka hookuuia ana o sewage, metala maoli me ka alapiʻi ka hoʻoponopono.

Electroplating bato hiki ke i o kuhiliʻole kila, kila, hoalaala ia me ka lula a me ka laholio. Hoikehonua, bata, welded mai kuina polymers i increasingly ke kūapoʻana metala la e hiki ai. Koho bato mea hilinaʻi nui ma luna o ka haku mele 'ana a me ka lehulehu o ka electrolyte a me ka hoʻohana mahana.

Palapala wai lako a me ka sewerage nenoai, a ma ka hapanui hihia manaʻo ma lalo o ka hoʻokomo ea bato a no hoi i mai polypropylene.

Ke Ana o ka laina hoʻoholo ma kona 'auhau, a Ana o galvanic bato ke komo iloko.

Galvanizing e wahi me ke kahua o ka wao wai me ka lehulehu kiʻekiʻe o ke kaumaha metala Ion. No laila, ka mea, e Uwao, i wae 'ia, neutralized, hoʻohana' Nine Inch māhuea palapala moʻopane, a me nā sorption keʻano o ka hanaʻana i loko o pahu i ka hana 'enekinia, polymers.

Kiniki electroplating ma ka hale

Galvanizing, hua mai la i ko lakou mau lima, ka mea i hoʻomaka me ke koho ana i kekahi mau kumuhana. Ke electrolyte paha e ka pāʻoihana o ke kiniki koloriside a hydrochloricʻakika i ka i puhi ia ka wai. Kēia no laila,-kapa solderingʻakika, i ka loa pinepine hoʻohana 'ia i loko o ka hale. Poe paahana etched kiniki ma sulfuricʻakika a me na pu ki aloha hoomakaukau ZnSO ₄ electrolyte, akā, i kēia kaʻina ka mea, no ka mea, o ka naoh produces wela a me ka pahū hydrogen. Ke electrolyte ma kekahi hihia e ole e he precipitate o insoluble paakai nā pōaka.

Pure kiniki hiki ke kuai i loko o kekahi hale kūʻai o Nine Inch reagents a ma ka Radio, a ua hiki ke loaa mai ka paakai iuo aaoa? A fuses, i ka malamaia, mai ka Soviet Union.

Galvanic bata hiki e ke aniani a ea ipu. Ia ihola ke kumu i hoʻonoho i ka anode a me ka cathode. Ka anode - he kiniki papa, i ka i ua pili mai ka mana lako "eia". Ka oi o ka anode, ka oiʻaʻahu i ka penaʻana ma luna o ka cathode huahana i ua noi aiiay ka penaʻana. Ke anode paha e he uuku, ka mea hiki ke kau ia a puni ka cathode i ka mamao i ka ili o ke kiniki lole komoʻuʻuku nona uniformly a me ka poʻe ma luna o nā mea a pauʻaoʻao. I ka cathode e pili ana "hua" mana kumu.

Pela hoi, aole ia ma ka hale i galvanizing plating enehana pono nā hoʻokolokolo pono, i ka hoʻomaʻemaʻe a me degreasing o nā māhele, e like me kona ho'ā hope i loko o kaʻakika pāʻoihana.

Mana lako - keia mea he kaʻa na pu ki aloha me ka incandescent kukui o haʻahaʻa i ka mana a me 'ē aʻe consumer i loko o ke kaapuni ana i ka mea pono ma ka huakai kaapuni i lalo nei a me ka mana lako me ka ikaika anakahi uila ma ka auoiaea. ʻO ka papa kuhikuhiE mea o ia ka mea, aole kokololio baila aʻela i o ka electrolyte i ka galvanizing.

Maoli galvanizing ia lŘlŘ ka wā o ka anode a me ka cathode e hōʻike 'ia ma ka electrolyte, a me ka uila huakai kaapuni ua paa. Ka hou ke kaʻina hana, i ka pūhaka o ka kiniki, ahu iho loaa ma luna o ka huahana.

Me ka galvanizing aiiay ka penaʻana ma luna o ka huina hoonui i kūlike loa,ʻaʻahu, a laumania, a me ka Nani Loa hopena. Ua Ua hoʻohana 'ia nā ma ka hana, a ma ka hale, hoʻowahāwahā i ka mea i ka mea lawe wastewater mai environmentally hoʻopōʻino neoneo.
