1. Kurapwa nguva isati yasvika: Kuti ubvise mafuta asina basa, marara ekunamira, uye tsvina kubva pamusoro pemuviri wemotokari kubva kufekitori yemuviri, firimu rezinc phosphate (3~5).㎛) inoiswa pamusoro pemuviri kuti iwedzere kunamira panguva yekuiswa pasi peganda (electrodeposition). Kuitira kudzivirira ngura yemuviri wemotokari.
- Kuchenesa muviri usati waungana: Mushure mekuunganidza muviri, unogezwa nemvura usati wabvisa mafuta.
- Kubvisa mafuta zvakanyanya: Kunobvisa mafuta mumuviri wemota.
- Sukurudza zvine mwero: Chinhu chinorapa chine titanium sechinhu chikuru, chinoita kuti pave nehuwandu hwakawanda hwema colloid pamusoro pesimbi kuti pave nekushanda kwakawanda kwekugadzira firimu re zinc phosphate rakakora kuti rigadzire makristaro akapfava uye akakora.
- Firimu reZinc phosphate: Firimu reZinc phosphate rinoiswa kusimbisa kunamira kwepasi pevhu uye kudzivirira ngura.
1) Kucheka kunotanga pachikamu che anode chesimbi chiri mumushonga wekuputira
2) Zvichienderana ne corrosion current, ma cations anodyiwa pa cathode, uye pH ye interface inokwira.
3) Colloid pamusoro inova nucleus uye inoumba crystallize
- Ovheni yakaoma nemvura: Maitiro ekubvisa hunyoro zvachose kubva pasi pevhu mushure mekunge maitiro ekugadzirisa apera.
※ Kutamisa kupisa nekuomesa nemaoko
Mushure mekufukidza muviri nefirimu rezinc phosphate ( ), geza nemvura woiomesa nemaoko. Kuomesa nemaoko inzira yekubvisa hunyoro zvachose kubva pachinhu chinofanira kuputirwa wobva waita maitiro anotevera ekupenda. Simudza tembiricha kuti hunyoro hupfuure kuburikidza nekupisa. Kuomesa (evaporation) chiitiko chinoitika kana tembiricha yenzvimbo yakasimba iri padyo yakaderera pane pombi yekufashaira uye kumanikidzwa kwemhepo kwakaderera pane kumanikidzwa kwemhepo. Kuchinja kwechikamu kuchaitika. Tembiricha nenguva inodiwa kuti choto chekuomesa chakachekwa nemaoko chinosiyana zvichienderana nezvinhu, ukobvu, uye chimiro chechinhu chinofanira kuputirwa. Kazhinji, maminetsi gumi pa120~150℃ zvakajairika, uye chikonzero chekukwidza tembiricha ndechekuwedzera kumanikidzwa kwemvura inoenderana netembiricha iyoyo uye kuoma nekukurumidza nekupa simba rekupisa rakawanda. Panguva ino, hapafanirwe kuve nekuchinja kwesimbi kana kemikari nekuda kwetembiricha.
1,Maitiro ekuisa electrodeposition: Maitiro ekugadzira firimu rekufukidza mukati/kunze kwemuviri wemotokari nekushandisa electrophoresis kuburikidza nemagetsi mushure mekunyudza muviri wemotokari nependi yekuisa electrodeposition, nechinangwa chekudzivirira ngura yemuviri wemotokari.
- Kuisa Electrodeposition: Kuisa Electrodeposition inzira yekupenda iyo pendi inonamirwa nemagetsi nekunyudza muviri wemotokari mumushonga wependi uye anode inoyerera kana cathode mumuviri wemotokari. Zvisinei, inzira yakakodzera kugadzirwa kwakawanda, uye zvakaoma kupenda patsva kana firimu rekufukidza rabatanidzwa uye magetsi asingachafambi.
- Sukurudza neDI
- Electrodeposition Drying Furnace: Kune cationic electrodeposition coatings, iyo inonyanya kushandiswa, chitofu chekuomesa kupisa chinoshandiswa nekuti firimu rakaiswa pamusoro rinogadziriswa nekupisa kwemvura nekupisa kwemvura (thermal curating) reaction. Tembiricha nenguva inodiwa pakupisa zvinosiyana zvichienderana nezvinhu, ukobvu, uye chimiro chechinhu chinofanira kuputirwa. Kana chiri chinhu chakatetepa chakafukidzwa, tembiricha yepamusoro i200-210°C uye tembiricha yekupisa chitofu i210-230°C, uye nguva yekupisa inowanzo kuve maminetsi makumi maviri kusvika makumi matatu kwemaminitsi gumi kana kupfuura kuti nguva yekupisa yechinhu chinofanira kuputirwa uye nguva yekubata 200-210°C.
- Kupukuta kweElectrodeposition: Kukuya zvikamu zvisina kusimba uye zvakabuda pamusoro kuti zvive zvakatsetseka.
2, Pendi yepakati: Iyi ndiyo nzira yekuisa pendi, iyo inowanzonzi primer. Inochenesa pamusoro kuitira kuti ganda repamusoro rinamire zvakanaka uye rinobatsira mukuvandudza kuramba kwengura. Ndinoshandisa ruvara rwakasiyana zvishoma pakati kuti ruenderane neruvara rweganda repamusoro.
- Maitiro epakati
- Choto chekuomesa chiri pakati nepakati
3, bhachi repamusoro: Maitiro ekuisa ruvara rwemotokari runoonekwa uye kupedzisa nependi inoonekera. Munguva pfupi yapfuura, nekuda kwemitemo yezvakatipoteredza, nezvimwewo, pendi dzinochengetedza nharaunda (zvinhu zvinopisa zvishoma) dziri kushandiswa zvishoma nezvishoma. Bvisa topcoat mushure mekupisa.

※ Kutamisirwa kwekupisa muchoto chekuisa nekuomesa chemagetsi/pakati/pamusoro pechitofu
Muchoto chekuomesa, kupisa kunotamisirwa pamusoro pepende nenzira mbiri.
Kutenderedza: Kuti firimu rinofukidza firimu risvike nyore nyore pakupisa kwekupisa, mhepo inoyerera nekukurumidza inodiwa, uye kutenderedza kwemhepo inotonhora kunowanikwa nekutenderedza mhepo inopisa muchoto ichiomesa nekumhanya kwemhepo (forced convection).
Kupisa Kunopenya: Madziro anopiswa kusvika mazana emadhigirii pamusoro pekupisa kwefirimu rinoputira muchoto chakagadzirwa zvakanaka, uye kupisa kunopfuudzwa pamusoro peganda rakapendwa nenzira imwecheteyo iyo chitofu chinodziisa muviri.
