Umbiko ngobuchwepheshe bokwelapha ubuso bepulasitiki yokufafaza —— Isixazululo sokuhlobisa esisebenza kahle kakhulu sokulwa nokugqwala

I. Umsebenzi kanye Nokuxazulula Izinkinga

1. Imisebenzi eyinhloko

• Ukumelana nokugqwala kwesikhathi eside: ifomu 60-120μm isembozo se-epoxy/polyester, isivivinyo sokufutha usawoti kuze kufike ku- Amahora angu-240-1000 (upende ojwayelekile wokufutha uthatha amahora angu-72-200 kuphela)
• Ukuhlobisa okunamandla: ukwesekwa Ikhodi yombala ye-Pantone engaphezu kuka-2000, ukuthungwa kwendawo kungakhethwa kube bushelelezi, kube nombala ophuzi, kube nombala wensimbi ocwebezelayo
• Ukushisa ngogesi: i-voltage yokuqhekeka>30kV/mm, vikela igobolondo lemishini kagesi
• Ukuphepha kwemvelo: akukho ukuguquguquka kwe-solvent (I-VOC=0), ngokuhambisana nesiqondiso se-RoHS/REACH

2. Isixazululo sezindawo zobuhlungu

II. Isimiso Sokusebenza

1. Indlela ephindwe kabili yokumuncwa kwe-electrostatic kanye nokwelapha okushisayo

2. Inqubo yokwakha ifilimu encane:

① Ukushaja i-powder → ② ukumuncwa okuqondile → ③ ukuncibilika → ④ ukuhlanganisa okuhlanganisiwe → ⑤, okwakha isakhiwo seseli elivaliwe

(Umfanekiso: isimiso sokusebenza sokumbozwa kwempuphu kagesi (ukumuncwa kwempuphu eshajiwe + ukupholisa izinga lokushisa eliphezulu))

III. Inqubo yokusebenza kwenqubo

Imisebenzi ejwayelekile

1. Ngaphambi kokwelashwa (60% ngobuningi)

• Ukususa ukukhuluphala (isixazululo se-alkaline, 50℃×8min) → ukuwasha ngamanzi → i-phosphate (isisindo se-membrane esekelwe ku-zinc 1.5-3g/㎡) → ukuwasha ngamanzi ahlanzekile → 120℃ ukomisa

2. Ukufutha ngogesi

• • Imishini: isibhamu sokufutha se-electrostatic esine-voltage ephezulu (i-voltage yokuphuma - 70kV)
• • Amapharamitha: umfutho womoya 0.5MPa, ibanga ukusuka ku-workpiece 200-300mm, ukulawula ukujiya kwefilimu ±10μm

3. Ukupheka nokubhaka

• • ijika lokushisa:
• izinga lokushisa langaphakathi (imizuzu eyi-10) → 180°C (imizuzu engama-20) → ukugcinwa kokushisa (imizuzu eyi-10) → ukupholisa

4. Izindinganiso zokuhlola ikhwalithi

• • Ukunamathela: indlela yokuklwebha (ASTM D3359) Ibanga eli-0 elifanelekile
• • Ubukhulu: igeyiji yobukhulu bamanje eddy ≥60μm

IV. Ukuqhathaniswa nezinye izinqubo

Icala elijwayelekile:

Ikhabhinethi yokuxhumana (ipulasitiki yokufafaza): Kukhethwe i-RAL7035 grey, ubukhulu befilimu bungu-80μm, kanti isivivinyo sokufafaza usawoti singamahora angu-480 ngaphandle kokugqwala

Izingxenye ezipendiwe zencazelo efanayo: ibhamuza lamahora angu-200, izindleko ziphansi ngo-30%, kodwa impilo imfushane ngo-60%

V. Isincomo sesimo sesicelo

• Isimo esithandwayo:

• ✅ Imishini yangaphandle (ibhokisi lokusabalalisa amandla/ikhabhinethi ye-5G)
• ✅ Izinto zasendlini (amaphaneli esiqandisi/izimbobo zomoya opholile)
• ✅ Izingxenye zesakhiwo ezinemibala (amashalofu/amathuluzi okubonisa)

• Sebenzisa izimo ngokucophelela:

• ❌ >200℃ indawo yokushisa okuphezulu (ukuphuzi kwe-resin ye-epoxy)
• ❌ Isimo sokucwiliswa kwe-asidi enamandla (ukumelana ne-asidi ne-alkali kubuthakathaka kune-electrophoresis)

Isiphetho: Ukufakwa kwe-spray sekuyindinganiso yegolide yokuvikela ukugqwala kwepuleti lensimbi ngezinzuzo ezintathu zokuvikelwa kwemvelo, ukuhlobisa kanye nokumbozwa. I-Mingli Metal ifakwe umugqa we-spray coating ozenzakalelayo kanye nohlelo lokushintsha umbala ngokushesha (), okunganikeza amabhizinisi izixazululo ezifika kanye kusukela ekukhetheni kuya ekukhiqizweni okukhulu.

Faka: isifutho senqubo yepulasitiki ye-spray yangempela yesehlakalo

Umfanekiso: umugqa wokukhiqiza wepulasitiki yokufutha okuzenzakalelayo ngokuphelele (ngaphambi kokwelashwa → igumbi elisebenza ngogesi → isithando sokushisa)
