Ixesha lokumisela: Ngokuqhelekileyo i-3-10 imizuzu, ilungelelaniswe ngokwezinto eziphathekayo kunye neemfuno zenkqubo.
Isiphakamiso soPhuculo: Sebenzisa itekhnoloji ye-phosphating yobushushu obuphantsi ukunciphisa ukusetyenziswa kwamandla, kwaye udibanise nesisombululo se-phosphating esisingqongileyo ukunciphisa uxinzelelo lokucocwa kwamanzi amdaka kwimizi-mveliso.
Icebiso lesi-6: Lawula amanqaku aphambili enkqubo yokufakwa kwe-electroplating
I-Electroplating inokubonelela ngeempawu ezintle zokuhombisa kunye nezikhuselayo, kodwa ifuna ulawulo oluchanekileyo lwenkqubo:
Ubuninzi bangoku kunye nobushushu kufuneka buhambelane ngokungqongqo. Umzekelo, xa ufaka igalvanizing, iqondo lobushushu kufuneka libe phakathi kwe20-30℃ kwaye uxinano lwangoku kufuneka lugcinwe ku-2-4 A/dm².
Uxinzelelo lwezongezo kwisisombululo se-electroplating kufuneka lubekwe esweni rhoqo ukuze kuqinisekiswe ukuguquguquka kunye nokuxinana kwengubo.
Qaphela: Ukucoca emva kwe-electroplating kubalulekile. Isisombululo esisele se-electroplating sinokubangela ukugquma okanye ukubola kumphezulu wengubo.
Icebiso lesi-7: I-Anodizing (ikhethekileyo kumalungu e-aluminiyam)
I-Anodizing yinkqubo engundoqo yokuphucula ukuxhathisa umhlwa kunye nesiphumo sokuhombisa samacandelo esinyithi e-aluminium:
I-voltage inconywa ukuba ilawulwe kwi-10-20 V, kwaye ixesha lokucubungula lihlengahlengiswa ngokweemfuno (imizuzu engama-20-60).
Ukudaya kunye nokutywinwa emva kwe-oxidation ngamanyathelo aphambili okuphucula umthamo we-antioxidant kunye nokuqina kombala.
Ubuchwephesha obuphezulu: Sebenzisa iteknoloji ye-micro-arc oxidation (MAO) ukuqhubela phambili ukuphucula ubulukhuni kunye nokuxhatshazwa kokugqoka ifilimu ye-oxide.
Icebiso lesi-8: Ukusila umphezulu kunye nokupolisha ukuphucula ukuchaneka
Umgangatho wonyango okumgangatho ophezulu awunakwahlulwa ekusileni kunye nokupholisha:
Ukukhetha iphepha leSandpaper: Ukusuka korhatyazo ukuya kocolekileyo, inyathelo ngenyathelo, umzekelo, sebenzisa kuqala 320#, emva koko utshintshele kwi-800# okanye umnatha ophezulu.
Ukusebenza okuhambelanayo: Isalathiso sokugaya kufuneka sihambelane nokuphepha imikrwelo enqamlezayo echaphazela ukubonakala.
Kwizixhobo zokusebenza ezineemfuno zegloss eziphezulu, ukupolisha kwesibuko kungasetyenziswa, kudityaniswe ne-polish paste okanye i-chromium oxide paste ukuphucula umphumo.
