Zithini iinkqubo zonyango eziqhelekileyo?

Inkqubo yokudala ungqimba lomhlaba kumphezulu wezinto ezenziweyo ezahlukileyo kwi-subtate ngokwemigqaliselo yemisebenzi, yomzimba, kunye neekhemikhali zaziwa njengonyango lomhlaba. Unyango lomphezulu lusetyenziselwa ukwanelisa iinkcazo zezinto ezifana nokuchasana nemveliso yemveliso, ukunxiba ukunganyangeki, kunye ne-aesthetics.

Ukongeza kwimilinganiselo ephambili, ukuxhathisa i-corrosion kwaye ujonge umbala kufuneka uthathele ingqalelo ngelixa ukhetha isikrelemnqa. KubaIzikrelemnqaIinkqubo zonyango eziphezulu zithanda i-oxidophotion, i-elektrophoresis, i-elektroplareting, iDacromet, kunye nezinye zisetyenziswa rhoqo.

Ngokutsho kombala womphezulu wesikali, inokwahlulwahlulwahlulwahlulwahlulwahlulwahlulwa kwezi zinto zilandelayo:

I-screen ezimnyama

Mnyama okuqhelekileyoIzikrelemnqaUbubanzi babandakanya unyango lwe-Oxidation olumnyama, i-elektroplating, kunye ne-electrophoresis.

Unyango lwe-Oxidation oluMnyama

Unyango lwe-Oxidation oluMnyama yindlela eqhelekileyo yonyango lwekhemikhali lemichiza, injongo kukuvelisa ifilimu ye-oxide kumphezulu wensimbi yokukhetha umoya kwaye uthintele i-runust.

Inkqubo kukusebenzisa i-oxidant eyomeleleyo ukunyanzela umphezulu wensimbi kwi-murdsse kunye ne-ferrofer felder of. Lo mkhulu omncinci we-ferrofer oxide unokukhusela ngokufanelekileyo ngaphakathi kwintsimbi kwi-oxidation. Yahlulwe yangamaqondo obushushu asezantsi kunye nobushushu obuphezulu.

I-Ferroferric Oxide enobushushu obuphantsi (malunga ne-350 ° C) imnyama emnyama, eyaziwa ngokuba imnyama. I-ferroferic oxide eyenziwa nge-oxidation kwiqondo lobushushu eliphezulu (malunga ne-550 ° C) sisibhakabhaka esiluhlaza okwesibhakabhaka, esaziwa ngokuba nonyango olubalaseleyo. Unyango oluhlaza okwesibhakabhaka luhlala lusetyenziswa kwimveliso yesixhobo, kwaye unyango lwabantsundu lusetyenziswa rhoqo kwimveliso yemizi mveliso.

I-oxidike i-serner yentsimbi ukuba ifune, i-ferrofer egudileyo ifuna i-oxidant eyomeleleyo. I-oxidant yomeleleyo iqulunqwe nge-sodium hydroxide, i-sodium nitite, kunye ne-trisodium phosphate. Xa ijika iblowu, phatha intsimbi ene-oxidant yomeleleyo, kwaye xa ijika imnyama, yiphathe ngesisombululo se-axidant esiqinileyo.

I-electropla

Ukufakwa kwe-elektroproplay yinkqubo yokusebenzisa i-electrolysis kwingubo ye-coat kwezinye iifilimu zensimbi okanye iifilimu zomgangatho wesinyithi. Injongo kukuphucula ukunqanda ukumelana, ukumelana nokunganyangeki, kunye ne-aesthetics.

Kukho iintlobo ezi-2 zokubekwa komnyama: Ukubekwa kwe-zinc emnyama kunye ne-nickel emnyama.

I-ZINC ezimnyama ze-ZIN

Ukubekwa kwe-zinc i-binc emnyama luhlobo lokuchasa i-oxidation yentsimbi, elungele iimveliso ze-hardware. I-Zinc isebenza kakuhle kwaye inyanzelekile ukuba ichukumise kwaye inomnyama emoyeni. Emva kokuziphakamisa, iphathwa nge-chromate ukuba igubungele ifilimu yokuguqula yekhemikhali kwi-zinc, ukuze isinyithi esisebenzayo sikwimeko eguqukayo, elunyango lwe-zinclar. Ifilimu yokwahlulwa inokwahlulwa ibe yi-Mhlophe iduthwe (i-winc) eblowu, iBlue Zinc), idyokhwe emnyama (i-zinc), idreyini ye-zinc), njl.

Ngokwesiqhelo, inkqubo ye-elektroplaift i-zinc i-wincre-ebuthathaka yokucoca-i-ecid-i-ecching-ye-Ecchicaning-ye-Ecpiating-yokucoca-yokutywina.

I-nickel emnyama iplate

Ngokwesiqhelo, inkqubo yokufaka i-elektroplating i-nickel i-nickel icwecwe-ukucocwa kwe-Acid isebenze - ukucocwa kwe-Acid - Ukucofa-Ukucocwa-Ukucoca-Ukucocwa-Ukucoca-Ukwenza ipeyinti-yokutsalwa kwepeyinti.

I-nickel emnyama ifunyenwe kwibhafu emnyama ye-Nickel iqulethe i-40-60% ye-Nickel, i-20-30% yinc, i-10-15% ye-sulfur, kunye ne-10% ye-10%. The black color is caused by the presence of black nickel sulfide in the coating due to the reduction of thiocyanate on the cathode to release sulfide ions. Umzantsi wobhedu wongezelelwa kwinkqubo, kwaye owona msebenzi uphambili kukwenza lula i-nickel kwi-post inkqubo kunye nokuphucula ukumelana nokunganyangeki kwesikere.

I-electrophoresis

I-electrophoreris ibhekisa kwi-phenomenon apho kuhlawuliswa amasuntswana ahamba ukuya kwi-electrodes yepropathi yombane echaseneyo phantsi kwesenzo secandelo lombane.

I-electrophoressis emnyama kukusetyenziswa kwendawo yombane yangaphandle ukwenza amasuntswana afana ne-pigments isisombululo se-electrophoressi esifakwe ngaphandle kunye nediphozithi kumgangatho we-electrod. I-elektrophoretic emnyama isetyenziswa ngokubanzi kwishishini, ithatha inkqubo emnyama njengomzekelo: Ukucoca-mpazamo-ipeyinti-ipeyinti ye-elektroniki. Inokwahlulwa kwi-Anodic electrophoressis (i-resin iba zii-ion ezingalunganga emva kwe-iOIRTION) kunye ne-COOTHOCROphoressis (i-resen iba yi-ions elungileyo emva kwe-elektrophoresis). Xa kuthelekiswa nenkqubo yokupeyinta, kungcono ukusebenza, ukungcoliseka okuncinci kunye nokwenzakala kwindalo esingqongileyo ziiyure ezingama-300 okanye ngaphezulu, kwaye indleko kunye nexabiso le-corosion ziyafana nenkqubo ye-dacromet.

I-screen emhlophe

I-screws emhlophe eqhelekileyo ibandakanya i-elektroplating emhlophe, i-zinc yam emhlophe, njalo njalo.

Ukufakwa kwe-elektropla

I-winc ye-zinc iplate

Inkqubo ye-elektroplating i-winc i-chincres yokutshaya-ukucoca i-Acid ye-Acid ye-Acid ye-Encro-Gal-Mud-White-White-White-White-White-Shicing. Umahluko ovela kwi-zinc yam mnyama kukuba akukho peyinti yokutywina ngaphezulu, kwaye isisombululo se-Despance sahlukile. Idlule emhlophe yifilimu engenamabala kwaye iguqukile i-binc axide ephantse ibe phantse i-chromium, ke imeko yokunganyangeki imbi ngakumbi kune-zinc yam emnyama, i-binc i-winc, kunye nombala we-zinc.

Ukuxhathisa i-corrosion ye-hinc emhlophe kungcono kuneyona nto imhlophe, kwaye imbonakalo yaso imnyama kune-nickel emhlophe.

I-electroplaitha i-NCECKL

Mhlophe i-nickel iplate

Inkqubo ye-elektroplating emhlophe i-wickel i-cicker iguqule-ukucoca-ukuvula ukusebenza-ukucocwa kwe-copper-pick-Ukucoca-ukucoca-okanye ukutywina. Inkqubo yokufakwa kwe-elektroplating emhlophe kunye ne-elektroplating i-nickel emnyama ngokusisiseko, umohluko uvela kwifomula yesisombululo se-electrop, ngaphandle kokongezwa kwe-zinc sulfide.

Ezinye ii-scred zeplanga

Umbala we-scred

Ukubekwa kweminye imibala ikakhulu kubandakanya i-chinc, i-zinc i-zinc, i-zinc ye-chinc, kunye ne-dacromet.

Inkqubo yokufaka i-electroplaitha ye-winc kwaye i-binc eluhlaza ilingana ne-zinc yam emhlophe. I-winc winc yifilimu ye-binc ye-binc ekhuselweyo ene-0.5-0.6 mg / dm2 ye-chromium kaTramium. Ukudluliselwa kwengubo eluhlaza kungenxa yokuba isisombululo se-Syspation sinee-phosphate ii-ions, kwaye ifilimu eluhlaza ebambeleyo idityaniswe nge-chromate ne phosphate.

Ukuxhathisa i-corrosion ye-chinc eluhlaza okwesibhakabhaka kungcono kunelo ye-winc, kunye nokuchasana ne-corrosion ye-zulc eluhlaza kungcono kunelo ye-winc i-winc.

Umbala uZinc unobuchasi obuhle kakhulu. Inkqubo yokuphumelela: Ukucoca-2% -3% ye-Nitric Acid ukuya ekukhanyiseni - ukucoca i-chromium - ukucocwa kwe-chromium - ukucoca-ukucoca-ukucoca-ukucoca-ukukhangela ukwaluphala. Iqondo lokushisa eliphantsi kakhulu ngexesha lokuphumelela liza kukhokelela kwimozulu yefilimu ecothayo kunye nefilimu emdaka. Iqondo lobushushu liya kubangela ukuba ifilimu ibe mninzi kwaye ikhululwe, kwaye umbuleli awuyi komelela. Kungcono ukulawula nge-25 degrees ukuqinisekisa ukuba ufumana umbala ofanayo wexesha elithile. Emva kokuphumelela, kufuneka ibhakiwe ukuphucula ukunamathela kunye nokunganyangeki kwefilimu.

Dacromet

I-Dacromet luhlobo olutsha lwe-anti-colossion yosulelo nge-zinc powder, i-aluminium powder, i-chromic acid, kunye namanzi aphambili njengezixhobo eziphambili. Inkqubo yokuhamba kwenkqubo yi-organction ye-organsent-Meding Polling-Spraise-Ding-Spraing-Spraing - Ukubhaka - Ukubhaka - ukubhaka.

Inzuzo yenkqubo ye-DACROmet kukuba ukunganyangeki kwe-corrosion kulungile, kodwa ukungabi nakhohlakeleyo kukuba ukungqengqeleka akuyi kuthunyelwa.
