Iposwe kwi 2016-06-22 I-Zinc flake yokugquma Luhlobo olutsha lokumelana nomhlwa, sele isetyenziswa ngokubanzi, inkqubo yokwaleka i-zinc flake ikakhulu sisiseko semathiriyeli, ukuthotywa, ukonakaliswa, ukwambathisa, ukufudumeza, ukunyanga, ukupholisa.
1. Degreasing: workpiece umphezulu kufuneka degreased, ngokubanzi ineendlela ezintathu: organic solvent degreasing, amanzi-based degreasing agent, ubushushu obuphezulu carbonization degreasing.Whether degreasing ngokucokisekileyo ngempumelelo, kuya kuchaphazela ngqo adhesion of ukutyabeka.
2. Derusting kunye deburring: workpiece kunye umhlwa okanye Burr zithintelwe ngokungqongqo ukutyabeka ngqo, kufuneka kudlule inkqubo derusting kunye deburring, le nkqubo kwaba ngcono ukusebenzisa indlela mechanical, ukuphepha acid ukuthintela embrittlement hydrogen.
3. Ukwambathisa:isixhobo sokusebenza emva kokuthoba kunye nokususa igrisi kufuneka kudiphu, ukutshiza okanye ukubrasha ngokukhawuleza.
4. Ukufudumeza kwangaphambili: i-workpiece ene-zinc flake yokwambathisa ipeyinti kumphezulu kufuneka ifudumeze kwangaphambili imizuzu eyi-10-15 ngokukhawuleza phantsi kobushushu be-120 + 20 ℃, ukwenza ulwelo lube ngumphunga wamanzi.
5. Ukunyanga: ii-workpieces emva kokufudumeza kwangaphambili kufuneka zinyange phantsi kwe-300 ℃ ubushushu obuphezulu, ixesha lokunyanga i-20-40 imizuzu, nako kunokunyusa ngokufanelekileyo ubushushu ukunciphisa ixesha lokunyanga.
6. Ukupholisa: Izinto zokusebenza emva kokunyanga kufuneka zipholiswe ngokupheleleyo ngesixokelelwano sokupholisa ukuze ziphinde zilungiswe okanye zihlolwe impahla.
