Inkcazo emfutshane:

Ukulungiswa kwangaphambili kokugquma kukulungiselelwa komphezulu wokugquma ngaphambi kokugquma kwaye sisiseko senkqubo yonke yokugquma.
Umgangatho wonyango lwangaphambi konyango uchaphazela ngokuthe ngqo umgangatho wokogquma, ngoko ke kufuneka siwuqwalasele.

Ingcaciso yeMveliso

Izixhobo ezahlukeneyo kunye neemveliso zazo kwinkqubo yokucubungula, ukuthuthwa, ukugcinwa, umphezulu wazo kulula ukuvelisa okanye
Ukuba unamathela kwizinto zangaphandle, ezifana ne-machining burr, ulusu lwe-oxide, ioyile, njl.njl., ezi zinto zingcolisayo kumphezulu ziya kuchaphazela ubuncinci bengubo kunye namandla okubopha kunye ne-matrix. Ukulungisa kwangaphambili i-coating ye-matrixInjongo kukususa ezi zinto kunye nokwenza utshintsho olufanelekileyo lweekhemikhali kumphezulu ukuze kubonelelwe ngeemfuno ezifanelekileyo zengubo ye-substrate, ukuze kwandiswe ukunamathela kwefilimu, kwandiswe ubomi benkonzo yefilimu, Nika amandla apheleleyo kwisiphumo sokukhusela kunye nesiphumo sokuhombisa sengubo.

Ngoko ke, fafaza umxholo ngaphambi kokuba ucutshungulwe. Ngokuyintloko ibandakanya ezi zinto zilandelayo:

Ukususa amafutha ngaphambi kokugquma

Intsimbi kunye namacandelo ayo kwinkqubo yokugcina kunye nokuthuthwa ukuze kusetyenziswe ukhuseleko lweoyile yokulwa nomhlwa, ishiti yentsimbi kwi-oyile yokutsala kufuneka isetyenziswe xa kusetyenzwa ngoxinzelelo, amacandelo kufuneka aqhagamshelane ne-emulsion xa kusetyenzwa, unyango lobushushu lunokunxibelelana neoyile yokupholisa, xa amacandelo edla ngokuba namabala eoyile kunye neHanJi yezandla zomqhubi, igrisi yamalungu kodwa kunye nokungcola okufana nokuhlala kunye nothuli. Konke oku, zonke iintlobo zeoyile kwiindawo azithinteli kuphela ukwakheka kwefilimu ye-phosphating, kodwa zichaphazela nokunamathela kwendlela yokusebenza yokomisa i-coating. Ukusebenza kokuhombisa kunye nokumelana nokugqwala. Itheyibhile 3-1 idwelisa unyango olwahlukileyo lwe-cold rolled steel plate. Isiphumo se-cathodic electrophoretic coating kukumelana nokugqwala.

I-Phosphating

I-Phosphating yinkqubo elula, ethembekileyo, engabizi kakhulu kwaye elula yokuphucula kakhulu ukumelana nokugqwala kwengubo yomphezulu wesinyithi. Isetyenziswe kakhulu ekhaya nakwamanye amazwe, ngakumbi kwingubo yemoto, esetyenziswa kakhulu kwiminyaka yakutshanje. Phantse i-100% yeenxalenye zepleyiti ezincinci kushishino lweemoto zi-phosphating. Inkqubo ye-Phosphating ibhekisa kumphezulu wesinyithi odibana nesisombululo se-asidi esiqulethe ityuwa ye-dihydrogen phosphate, i-chemical reaction kwaye iveliswa kukuzinza komphezulu wesinyithi we-inorganic compound membrane layer yendlela yonyango lweekhemikhali zomphezulu kunye nefilimu eveliswe ebizwa ngokuba yi-phosphating film.

Umgaqo wefilimu ye-phosphate

Ifilimu ye-phosphating ikwazile ukubonelela ngesiseko esifanelekileyo sokupeyinta ipeyinti, kungenxa yesiphumo esilandelayo:
1) Ibonelela ngomphezulu ococekileyo, ofanayo, ongenamafutha ngokusekelwe ekususeni amafutha ngokupheleleyo
2) kuphucula ukunamathela kwefilimu yendalo kwi-substrate ngenxa yesenzo somzimba kunye neekhemikhali. Akunzima ukuqonda ukuba isakhiwo esineembobo sefilimu ye-phosphating sandisa indawo yomphezulu we-substrate, ukuze indawo yokudibanisa phakathi kwezi zimbini inyuke ngokulinganayo, kwaye ukuvuleka okuzuzisayo phakathi kwezi layers zimbini zefilimu kuveliswe. Kwangaxeshanye, ukusebenzisana kweekhemikhali phakathi kwe-unsaturated resin kunye ne-phosphate crystal nako kwandisa amandla ayo okubopha.
3) inika umaleko wokuzihlukanisa ozinzileyo ongekho mqhubi, xa sele umonakalo wokwambathisa, unendima yokuthintela ukugqwala, ingakumbi kwi-anode incision. Ingongoma yokuqala idla ngokunganakwa. Kuphela ngokupheleleyo kwi-oyile ukwenza ifilimu ye-phosphating eyanelisayo. Ngoko ke ifilimu ye-phosphating ngokwayo yeyona mpembelelo ibonakalayo yetekhnoloji yonyango lwangaphambi konyango inokuthenjwa kakhulu.
