1. Tomua maimoatanga: Hei tango i te hinu kore, te toenga whakapiri, me nga poke mai i te mata o te whakaurunga tinana o te waka mai i te wheketere tinana, he kiriata zinc phosphate (3~5㎛) ka whakamahia ki te mata o te tinana kia piki ake te piri i te wa e whakakikoruatia ana (electrodeposition).tukanga.Mo te kaupapa o te tiaki waikura tinana o te motuka.
- I mua i te horoi: I muri i te huihuinga o te tinana, ka horoia ki te wai i mua i te whakakorenga matua.
- Ko te whakaheke matua: Ka tango hinu mai i te tinana o te waka.
- Horoi herenga: He kaihoko maimoatanga me te titanium te waahanga matua, te hanga i te maha o nga colloids i runga i te mata whakarewa hei whakanui ake i te tauhohenga mo te hanga i te kiriata zinc phosphate kia puta ai nga tioata pai me te kiko.
- Kiriata konutea phosphate: Ka whakamahia he kiriata zinc phosphate hei whakapakari i te piri o te koti o raro me te aukati i te tauhohenga waikura.
1) Ka timata te tarai i te wahanga anode o te pepa rino i roto i te otinga paninga
2) I runga i te waikura o naianei, ka pau nga cations i te cathode, ka piki ake te pH o te atanga.
3) Ko te Colloid kei runga i te mata ka noho hei karihi ka tioata
- Umu maroke wai: Ko te tukanga o te tango katoa i te makuku mai i te tïpako i muri i te otinga o te mahi i mua i te maimoatanga.
※ Te wera me te whakamaroke i te whakamaroke ringa
I muri i te hipoki i te tinana ki te kiriata zinc phosphate ( ), horoia ki te wai ka whakamaroke ma te ringa.Ko te whakamaroke-a-ringa he tukanga mo te tango katoa i te makuku mai i te mea ka pania, ka mahi i te mahi peita e whai ake nei.Whakanuia te pāmahana ki te whakaeto i te makuku ma te whakawhiti wera.Ko te whakamaroke (te whakaetonga) he ahuatanga ka puta ina he iti iho te pāmahana o te mata totoka e pa ana ki te ira koropuha, ka iti ake te pehanga hau i te pehanga kohu.ka puta te huringa wahanga.He rereke te pāmahana me te wa e hiahiatia ana mo te oumu whakamaroke-ringa i runga i te papanga, te matotoru, me te ahua o te mea ka pania.I te nuinga o te waa, 10 meneti i te 120~150 ℃ he mea noa, ko te take mo te whakanui ake i te pāmahana ko te whakanui ake i te pehanga kohu o te wai e rite ana ki taua pāmahana me te maroke tere ma te whakarato i te kaha o te wera.I tenei wa, kia kaua he whakarewa, he huringa matū ranei na te pāmahana.
1,Ko te tukanga hiko: He tukanga hanga kiriata whakakikorua ki roto/waho o te tinana o te waka ma te whakamahi i te hiko hiko i muri i te ruku i te tinana o te waka ki te peita hiko, hei aukati i te pirau o te tinana o te waka.
- Te Hiko: Ko te peita hiko he tukanga peita e hono ana te peita ma te ruku i te tinana o te motuka ki roto i te wairewa peita me te rere anode, cathode ranei i roto i te tinana o te motuka.Heoi, he tikanga e tika ana mo te hanga papatipu, he uaua ki te peita ano i te wa e piri ana te kiriata paninga me te kore e rere te hiko.
- DI horoi
- Umu whakamaroke Electrodeposition: Mo nga paninga electrodeposition cationic, e whakamahia ana i te nuinga o te waa, ka whakamahia he oumu whakamaroke-wera na te mea ko te kiriata kua whakatakotoria ki runga i te mata ka whakaenehia e te waiariki waiariki na roto i te hononga whakawhiti waiariki (te whakamaroke wera).Ko te pāmahana me te wa e hiahiatia ana mo te whakamahana wera he rereke i runga i te papanga, te matotoru me te ahua o te mea ka pania.I roto i te take o te mea whakakikoruatia ahua angiangi, ko te pāmahana mata he 200-210°C me te pāmahana oumu whakaora ko te 210-230°C, a ko te wa whakawera he 20-30 meneti katoa mo te 10 meneti neke atu ranei mo te te wa whakamahana o te mea kia pania me te 200-210°C te wa pupuri.
- Te whakakorikori hiko: Korohia nga wahi taratara me te puhoi o te mata kia maeneene ai.
2、Peita Haurua: Koinei te tukanga o te peita peita, e kiia ana he tuatahi.Ka horoi i te mata kia piri pai ai te koti o runga me te whai waahi ki te whakapai ake i te waikura.Ka whakamahia e ahau he tae paku rereke mo te waenganui kia rite ki te tae o te koti o runga.
- Te tukanga takawaenga
- Umu whakamaroke reo
3. koti runga: Te tukanga o te tono i te tae waka kitea me te whakaoti ki te peita maramara.Ina tata nei, na nga ture taiao, me era atu mea, ka whakamahia haeretia nga peita hoahoa-taiao (he iti te kiko o te matū wariu).Maama i muri i te koti o runga
- tukanga koti runga
- Umu whakamaroke topcoat
※ Te whakawhiti wera i roto i te whakamahana hiko / waenganui / runga whakamahana me te oumu whakamaroke
I roto i te oumu whakamaroke, ka whakawhitia te wera ki te mata peita i nga huarahi e rua.
Convection: Kia ngawari ai te tae ki te pāmahana whakamaroke waiariki o te kiriata paninga, me tere te rere o te hau, a, ka whiwhi te convection tere teitei ma te huri i te hau wera i roto i te oumu whakamaroke i te tere o te hau (te kaha kaha).
Te wera o te wera: Ka wera te pakitara ki te maha rau nga nekehanga i runga ake i te whakamahana o te kiriata paninga i roto i te oumu whakamaroke i hangaia, a ka tukuna te wera wera ki te mata peita i te ahua o te whakamahana i te tinana.
