Iposwe kwi 2018-09-17Inkqubo yokugquma i-Dacromet: i-raw material yenziwe kwi-coating e-soluble yamanzi, kwaye emva koko igqunywe phezu kwendawo yokusebenza eqhutywe ngaphambili, i-pre-baked kunye ne-sintered ukwenza i-inorganic film layer.Inkqubo esisiseko yile ilandelayo: ukususwa kwesixhobo sokusebenza → ukugxothwa (ukuqhushumba) → ukudipha ukutyabeka (okanye ukutshiza) → ukomisa → ukubhaka kwangaphambili → ukuthambisa → ukupholisa → ukuhlola → ukupakisha.
1. Ukunciphisa amafutha: Ukunciphisa isinyibilikisi se-organic okanye isisombululo sealkaline.Ngokombono wokukhusela indalo, kufuneka kusetyenziswe i-alkaline degreasing.Emva kokuba i-workpiece ye-degreased, umphezulu kufuneka ufakwe emanzini.
I-workpiece ifakwe kwisitya esivaliweyo, kwaye i-ejenti yokucoca ifakwe kwixinzelelo eliphezulu kwaye ifafazwe ukucoca.Ekubeni umphezulu we-workpiece yi-oyile ye-mineral anti-rust, i-surfactant edibeneyo ene-emulsified dispersion kunye negunya elihle lokunyibilika likhethiwe.
2. Ukudubula okuqhushumbayo: Ukuze kuthintelwe ukungcoliswa kwehydrogen kunye nokungcoliseka kwendalo, ukurusa akusetyenziselwa ukuchola, kodwa kusetyenziswa ukudubula.Umatshini wokukrola wentsimbi osetyenziswa kumatshini wokuqhumisa unobubanzi obususela kwi-0.1 ukuya kwi-0.6 mm, kwaye uthululwe ngumoya oxinanisiweyo.Uthuli olususiweyo luqokelelwa ngumqokeleli okhethekileyo wothuli kwaye lugxininise.Ukunciphisa kunye nokunciphisa kufuneka kube ngokucokisekileyo, ngaphandle koko ukunamathela kunye nokuxhatshazwa kwe-corrosion of the coating kuya kuncitshiswa.
3. I-Dip coating: I-workpiece ephathwayo igxininiswe kwisisombululo se-Dacromet esakhiwe ngaphambili.Isixhobo sokusebenza sihlala sidipha sigqunywe kangangemizuzu emi-2 ukuya kwemi-3 phantsi kokungcangcazela kancinane emva koko somiswe.Ukuba i-workpiece inkulu, yitshize.Emva kokugquma idiphu okanye ukutshiza, ukuba kukho ukungalingani okanye ukuvuza kokuvuza emva kokuhlolwa, kunokusetyenziswa ngebrashi yokugqoka.
4. Ukubhaka kwangaphambili, ukunyanga: I-workpiece edibeneyo ifakwe kwi-belt yensimbi engenasici, kwaye i-workpieces ayivumelekanga ukuba ihambelane nomnye, ifake kwisithando somlilo se-10-30 imizuzu, kwaye uphilise imizuzu eyi-15 ukuya kwe-30.Ukubhaka kwangaphambili, ubushushu bokunyanga kunye nexesha lixhomekeke ubukhulu becala kunye nobukhulu bomsebenzi kunye nolwelo olwahlukileyo.Isantya sokuhambisa umnatha wentsimbi engenastainless steel mesh conveyor silawulwa.
5. Emva kokunyanga: Ukuba ubuso be-fastener bunzima emva kokunyanga, ubuso be-fastener bunokucocwa nge-brush enzima.
