ISurley yingqokelela yeUnyango lwangaphambili kunye neenkqubo ze-electrophoresis Indawo yokutshiza i-oveni inkqubo yokuhambisa ibhentshi yokuvavanya ishawa iteknoloji yokhuselo lokusingqongileyo Izincedisi indawo yokusebenzelaisimbo zonke kwivenkile enye.

Unyango lwangaphambili kunye nenkqubo ye-electrocoating

Unyango lwangaphambili kunye nenkqubo ye-electrocoating Umfanekiso obonakalayo
  • Unyango lwangaphambili kunye nenkqubo ye-electrocoating
  • Unyango lwangaphambili kunye nenkqubo ye-electrocoating
  • Unyango lwangaphambili kunye nenkqubo ye-electrocoating
  • Unyango lwangaphambili kunye nenkqubo ye-electrocoating
  • Unyango lwangaphambili kunye nenkqubo ye-electrocoating

Inkcazelo emfutshane:

I-Coating pretreatment kukulungiswa kwendawo yokugquma ngaphambi kokugquma kwaye isiseko senkqubo yonke yokwaleka.
Umgangatho pretreatment ngqo ichaphazela yonke umgangatho ukutyabeka, ngoko ke kufuneka sinikele ingqalelo kuyo.

Ingcaciso yeMveliso

Izinto ezahlukeneyo kunye neemveliso zazo kwinkqubo yokucubungula, ukuthutha, ukugcinwa, ubuso bayo bulula ukuvelisa okanye
intonga into yangaphandle, efana ne-machining burr, isikhumba se-oxide, ioli, njl., ezi zingcoliso zangaphandle ziyakuchaphazela ukuxinana kwengubo kunye namandla okudibanisa kunye ne-matrix. Ukwaleka kwangaphambi kokunyangwa kweyona njongo iphambili kukususa ezi zinto kwaye kwenziwe uguqulo olufanelekileyo lweekhemikhali zomphezulu ukubonelela ngokufanelekileyo iimfuno zoKwaleka kwi-substrate, ukwenzela ukwandisa ukunamathela kwefilimu, ukwandisa ubomi benkonzo yefilimu, Nika umdlalo opheleleyo kwindawo ekhuselayo. umphumo kunye nempembelelo yokuhlobisa yokugqoka.

Ke ngoko, fafaza umxholo ngaphambi kokucubungula. Ibandakanya ikakhulu le miba ilandelayo:

Ukuhlamba ngaphambi kokutya

Intsimbi kunye neengxenye zayo kwinkqubo yokugcina kunye nokuthutha ukusebenzisa ukhuseleko lweoli ye-antirust, i-sheet metal workpiece kwi-oyile yokuzoba kufuneka isetyenziswe xa kusenziwa uxinzelelo, iinxalenye kufuneka zidibanise i-emulsion xa i-machining, unyango lobushushu lunokuqhagamshelana neoli yokupholisa, xa iindawo zihlala zineoli. amabala kunye ne-HanJi yezandla zomqhubi, igrisi yamalungu kodwa kunye nokungcola okufana rhoqo kunye nothuli oluxutywe kunye Konke oku, zonke iintlobo zeoli kwiindawo azithinteli nje ukubunjwa kwefilimu ye-phosphating, kodwa kuchaphazela ukunamathela ukomisa ukusebenza kokuhombisa kunye nokuxhathisa umhlwa. Impembelelo ye-cathodic electrophoretic coating on corrosion resistance.

I-Phosphating

I-Phosphating yinkqubo elula, ethembekileyo, enexabiso eliphantsi kunye nefanelekileyo yokuphucula kakhulu ukuxhatshazwa kwe-corrosion of metal surface coating. Isetyenziswe ngokubanzi ekhaya nakwamanye amazwe, ngokukodwa kwi-coating yemoto, esetyenziswa kakhulu kwiminyaka yamuva. Phantse i-100% yamacandelo epleyiti ebhityileyo kushishino lweemoto iphosphating Inkqubo yePhosphating ibhekisa kumphezulu wesinyithi onxibelelana nesisombululo seasidi esiqulethe ityuwa yedihydrogen phosphate, ukusabela kweekhemikhali kwaye iveliswe kumphezulu wozinzo lwesinyithi senwebu ye-inorganic compound enganyibilikiyo. indlela yonyango lwekhemikhali yomphezulu kunye nefilimu eyenziweyo ebizwa ngokuba yifilimu ye-phosphating.

Umgaqo wefilimu yePhosphate

Ifilimu ye-phosphating yakwazi ukubonelela ngesiseko esifanelekileyo sokutyabeka ipeyinti, ngenxa yesi siphumo silandelayo:
I-1) Inika indawo ecocekileyo, iyunifomu, i-grease-free-free ngesiseko sokunciphisa ngokupheleleyo
I-2) iphucula ukunamathela kwefilimu ephilayo kwi-substrate ngenxa yesenzo somzimba kunye neekhemikhali Akunzima ukuqonda ukuba i-porous structure yefilimu ye-phosphating yandisa ummandla we-substrate, ukwenzela ukuba indawo yokudibanisa phakathi kwezi zibini inyuke ngokuhambelanayo, kwaye ukunyanzeliswa okuzuzisayo phakathi kweemaleko zefilimu ziveliswa. Kwangaxeshanye, intsebenziswano yeekhemikhali phakathi kweresin engaxutywanga kunye nekristale yephosphate nayo yongeza amandla ayo okubopha.
3) ukubonelela ngokuzinzileyo non-conductive yodwa umaleko, kanye umonakalo yokwambathisa, inendima inhibition umhlwa, ingakumbi i-anode incision Inqaku lokuqala lidla ngokungahoywa Kuphela ngokupheleleyo ukuya best oyile ukwenza ifilimu phosphating eyanelisayo Ngoko. ifilimu ye-phosphating ngokwayo iyona mpembelelo enembile kakhulu yeteknoloji yonyango yangaphambili yeyona nto ithembekileyo yokuzihlola.
