Amaphrofayili e-aluminium powder spray coating line

Ukumbozwa kwempushana kusetshenziswa umgomo wokufafaza nge-electrostatic of dry powder adsorption kumaphrofayili ensimbi e-aluminium, ngemva kwe-200 ℃ izoso yezinga lokushisa eliphezulu, impushana yelashwa yaba ungqimba lwama-microns angu-60 ogqinsi oluqinile olugqamile. Yenza indawo yomkhiqizo ibe bushelelezi futhi ibe nombala oqinile ngokumelana ne-asidi, ukumelana ne-alkali, ukumelana nomthelela, ukumelana nokugqokwa, ingamelana nemisebe eqinile ye-ultraviolet nokuguguleka kwemvula ene-asidi isikhathi eside, akubonakali ukunamathela okunamathelayo, ukufiphala, ukuxebuka nezinye izenzakalo. Amaphrofayili e-aluminium enziwe ngempuphu anempilo yesevisi yeminyaka engama-30 ngaphansi kwezimo ezijwayelekile. I-surface coating yayo eminyakeni engu-5-10 ukuqinisekisa ukuthi umbala awufi, awushintshi umbala, awuqhekeki. Ukumelana nesimo sezulu kanye nokugqwala kungcono kunokwehluka kombala ojwayelekile we-aluminium.

Ilayisha

Ikhwalithi yenqubo yokwelashwa yangaphambi kokwelashwa ithinta ngokuqondile ikhwalithi yefilimu yokugcoba impushana, ukwelashwa kwangaphambili akukuhle, okuholela ekubeni kube lula ukukhipha ifilimu, ukubhuqa kanye nezinye izenzakalo.

Ukuze ishidi metal izitembu izingxenye ingasetshenziswa amakhemikhali pretreatment indlela. Iningi lokugqwala noma indawo yokusebenza ewugqinsi, ukusetshenziswa kwe-sandblasting, ukuqhunyiswa kwesibhamu nezinye izindlela zokususa ukugqwala, kodwa ukwehla ngomshini kufanele kuqinisekise ukuthi indawo yokusebenza ihlanzekile futhi ayinasikali.

Ngokwezinga lokukhubazeka ku-workpiece scraping conductive putty, ngemuva kokumisa nge-sandpaper yokugaya bushelelezi, ungenza inqubo elandelayo.

Uma kunezingxenye ezithile ze-workpiece ezingadingi ukumbozwa, zingambozwa nge-adhesive evikelayo, njll, ngaphambi kokushisa ukuze ugweme ukufafaza phezu kokugqoka.

Ukushisa kuqala akudingekile. Uma kudingeka i-coating ewugqinsi, i-workpiece ingashiswa ibe ngu-100-160 ℃, okungase kwandise ukushuba kwe-coating.

Ijeneretha ye-electrostatic ngokusebenzisa umlomo wesibhamu senaliti ye-electrode iye endaweni yokusebenza ukuze ikhulule i-high-voltage electrostatic (negative), i-electrostatic high-voltage evela emlonyeni wesibhamu wempushana kanye nengxube yomoya ecindezelwe kanye ne-electrode ezungeze i-ionization yomoya (inkokhelo engalungile). I-workpiece ngokusebenzisa ama-hangers ngokusebenzisa i-conveyor link ground (i-grounding pole), ukuze isibhamu kanye nendawo yokusebenza yenze inkambu kagesi phakathi kwempushana emandleni kagesi kanye nokucindezela komoya ocindezelwe ngaphansi kokucindezela okuphindwe kabili ebusweni bomsebenzi, ukuthembela ekukhangekeni kwe-electrostatic ebusweni bomsebenzi ukuze kwakhiwe ungqimba lwe-coating efanayo.

Ngemuva kokufafaza i-workpiece ngokusebenzisa iketanga lokuthutha endaweni yokushisa yokubhaka engu-180 ~ 200 ℃, futhi ufudumale isikhathi esihambelanayo, (imizuzu engu-15-20) ukuze ukuncibilika, ukulinganisa, ukuphulukisa, ukuze sithole umphumela we-workpiece surface thina. funa. (Izimpushana ezihlukene zihlukile ekushiseni kokubhaka kanye nesikhathi). Yilokhu okufanele sikunake ohlelweni lokwelapha.

Ngemuva kokuthi ukugqoka sekuphulukisiwe, susa isivikelo futhi usike ama-burrs.

Ngemva kokuphulukisa ucezu lokusebenzela, ukuhlolwa okuyinhloko kwansuku zonke kokubukeka (kungakhathaliseki ukuthi bushelelezi futhi kukhanyayo, noma ngaphandle kwezinhlayiya, ukuncipha nokunye ukukhubazeka) nokuqina (ukulawula ngo-55 ~ 90μm). Kumaphutha atholiwe njengokuvuza, iphinifa, ukulimala, ibhamuza, njll., ucezu lokusebenza luzolungiswa noma lufafazwe kabusha.

Ngemuva kokuhlolwa, imikhiqizo eqediwe iyahlungwa futhi ibekwe elolini lezokuthutha kanye nebhokisi le-turnover, futhi ihlukaniswe komunye nomunye ngokupakisha izinto ezithambile ezifana nephepha legwebu nefilimu ye-bubble ukuvimbela imihuzuko nokuhuzuka.
