Kuthunyelwe ku 2018-09-17Inqubo yokumboza i-Dacromet: i-raw material yakhelwe ibe yi-coating encibilikayo emanzini, bese imbozwa phezu kwe-workpiece eselashwe ngaphambilini, ibhakwe ngaphambili futhi ifakwe emanzini ukuze kwakhiwe ungqimba lwefilimu ye-inorganic.Inqubo eyisisekelo imi kanje: umsebenzi wokukhipha amafutha → ukucisha (ukuqhuma) → ukugcotshwa kwe-dip (noma ukufutha) → ukomisa → ukubhaka ngaphambilini → ukucwilisa → ukupholisa → ukuhlola → ukupakisha.
1. Ukwehlisa amafutha: Ukwehlisa isincibilikisi esiphilayo noma isixazululo se-alkaline.Ngokombono wokuvikelwa kwemvelo, ukukhishwa kwe-alkaline kufanele kusetshenziswe.Ngemuva kwe-workpiece e-degreased, ingaphezulu liyadingeka ukuthi limanziswe ngamanzi.
I-workpiece ifakwe esitsheni esivaliwe, futhi i-ejenti yokuhlanza yethulwa ngokucindezela okukhulu futhi ifafazwe ukuze ihlanzwe.Njengoba ingaphezulu le-workpiece lingamafutha amaminerali anti-rust, i-surfactant ehlanganisiwe ene-dispersion emulsified namandla amahle okuncibilika akhethiwe.
2. Ukuqhuma kwesibhamu: Ukuze ugweme ukungcoliswa kwe-hydrogen kanye nokungcoliswa kwemvelo, ukugqwala akusetshenziselwa ukuqoqa, kodwa kusetshenziswa ukuqhuma kwesibhamu.Umshini wokuchama wensimbi osetshenziswa emshinini wokudubula unobubanzi obusuka ku-0.1 kuye ku-0.6 mm, futhi uthululwa umoya ocindezelwe.Uthuli olususiwe luqoqwa umqoqi okhethekile wothuli futhi lugxiliswe.Ukunciphisa nokwehliswa kufanele kube okuphelele, ngaphandle kwalokho ukumelana nokunamathela nokugqwala kwe-coating kuzoncishiswa.
3. I-Dip coating: I-workpiece ephathwayo icwiliswa kusixazululo se-Dacromet esakhiwe ngaphambilini.Ucezu lokusebenzela luvamise ukucwiliswa lumbozwe imizuzu emi-2 ukuya kwemi-3 ngaphansi kokunyakaziswa kancane bese lomiswa.Uma i-workpiece inkulu, fafaza.Ngemuva kokugcotshwa kwe-dip noma ukufafaza, uma kukhona ukungalingani noma ukuvuza kokugqoka ngemuva kokuhlolwa, kungasetshenziswa nge-brush coating.
4. Ukubhaka kwangaphambili, ukuphulukiswa: I-workpiece ehlanganisiwe ibekwe ebhandeni lensimbi engenasici, futhi ama-workpieces awavunyelwe ukunamathela komunye nomunye, faka isithando somlilo esishisayo imizuzu engu-10-30, bese uphulukisa imizuzu engu-15 kuya kwangu-30.I-pre-baking, izinga lokushisa lokuphulukisa kanye nesikhathi ngokuyinhloko kunqunywa ubukhulu be-coating kanye nobukhulu be-workpiece kanye noketshezi oluhlukene lokumboza.Isivinini sokudlulisa sebhande lensimbi engenasici siyalawulwa.
5. Ngemuva kokwelashwa: Uma ingaphezulu le-fastener lilukhuni ngemva kokuphulukiswa, ingaphezulu le-fastener lingahlanzwa ngebhulashi eliqinile.
