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

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. I-Coating pretreatment ye-mainInjongo kukususa ezi zinto kwaye yenze ukuguqulwa kweekhemikhali ezifanelekileyo zomgangatho wokubonelela ngokufanelekileyo Iimfuno zoKwaleka ze-substrate, ukwenzela ukwandisa ukunamathela kwefilimu, ukwandisa ubomi benkonzo yefilimu, Nika umdlalo opheleleyo kwisiphumo sokukhusela kunye nesiphumo sokuhombisa sokugquma.

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

Ukuhlamba ngaphambi kokutya

Steel kunye neendawo zayo kwinkqubo yokugcina kunye nokuthutha ukusebenzisa ukhuseleko lweoli ye-antirust, i-sheet metal workpiece kwi-oyile yokuzoba kufuneka isetyenziswe xa kusenziwa uxinzelelo, iindawo kufuneka ziqhagamshelane ne-emulsion xa machining, unyango lobushushu lunokuqhagamshelana neoli yokupholisa, xa iinxalenye zihlala zineoli ye-oyile kunye ne-HanJi yezandla zomqhubi, igrisi yamacandelo kodwa kunye nokungcola okunje rhoqo kunye nothuli oluxutywe kunye nothuli oluxutywe kunye ne-oyile ephazamisayo kuphela. bhanyabhanya, kodwa kwakhona kuchaphazela ukuncamathelisa ukomisa ukusebenza kokuhombisa kunye nokumelana nomhlwa Itheyibhile 3-1 idwelisa ukunyangwa okwahlukileyo kwepleyiti yentsimbi eqengqelekayo. 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% yeendawo zepleyiti ezibhityileyo kushishino lwemoto ziyi-phosphating Inkqubo ye-Phosphating ibhekisa kumphezulu wesinyithi onxibelelana nesisombululo se-asidi esinetyuwa ye-dihydrogen phosphate, ukusabela kweekhemikhali kunye neveliswa kukuzinza komphezulu wesinyithi womaleko ongenakunyibilika wekhompawundi ye-inorganic yendlela yokunyanga imichiza 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 ye-organic kwi-substrate ngenxa yesenzo somzimba kunye neekhemikhali Akunzima ukuqonda ukuba isakhiwo se-porous sefilimu ye-phosphating sandisa indawo ephezulu ye-substrate, ukwenzela ukuba indawo yokudibanisa phakathi kwezi zibini inyuke ngokuhambelanayo, kunye nenzuzo yokubambisana phakathi kweengqungquthela ezimbini zefilimu zenziwe. Kwangaxeshanye, intsebenziswano yeekhemikhali phakathi kweresin engaxutywanga kunye nekristale yephosphate nayo yongeza amandla ayo okubopha.
3) ukubonelela ngokuzinzileyo non-conductive yodwa umaleko, kanye umonakalo ukutyabeka, inendima inhibition umhlwa, ingakumbi ngenxa ye-anode incision Inqaku lokuqala lidla ngokungakhathalelwa Kuphela ngokupheleleyo ukuya kweyona oyile ukwenza ifilimu phosphating eyanelisayo Ngoko ifilimu phosphating ngokwayo isiphumo esona ngqiqo kakhulu i-pretreatment self-technology ethembekileyo.
