Mune ine mavara egirazi bhodhoro rekupfapfaidza coating process, yakazara otomatiki yekupfapfaidza yekupendi michina inoita basa rakakosha, uye kuita kwayo uye kugadzikana kunokanganisa zvakananga kunaka kwechigadzirwa chekupedzisira. Tichitora Youbang Coating Equipment Company semuenzaniso, inotarisa kutsvagisa nekuvandudzwa uye kutengesa kwemidziyo yekupotera, yakazvipira kupa vatengi mhinduro imwe-yekumisa kupfapfaidza. Kambani haingosimbise kuita kwechigadzirwa uye kunaka kwayo asiwo inotarisisa ruzivo rwevatengi, ichipa rutsigiro rwakakwana rwehunyanzvi uye mushure me-vimbiso yekutengeswa panguva yekuputirwa negirazi remavara bhodhoro rekupfapfaidza kuti ive nechokwadi chekutonga nekugadzirisa panguva yese.
I. Kuumbwa uye Kufurira Zvinhu zveSpray Coating Production Line
Girazi bhodhoro rekupfapfaidza yekuputira mutsara wekugadzira kazhinji rine zvinhu zvakakosha senge yekupfapfaidza dumba, pamusoro pepamusoro bhandi rekutakura, uye ovheni yekuomesa. Uye zvakare, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune pretreatment nhanho, kunyanya kuyerera kwemvura yetsvina inogadzirwa panguva yekuchenesa bhodhoro regirazi, kusangana nekuchengetedza kwezvakatipoteredza zvinodiwa. Hunhu hwekupfapfaidza kupfapfaidza hune hukama zvakanyanya kune zvakati wandei, zvinosanganisira kushanda kwekurapa kwemvura, kuchena kweiyo workpiece pamusoro, conductivity yehoko, kudzora vhoriyamu yemhepo, chiyero chekushandisa hupfu, uye hunyanzvi hunyanzvi hwevanoshandisa.
II. Specific Spraying Process Matanho
◆ Pretreatment Stage: Usati wapfapfaidza, mabhodhoro egirazi anofanirwa kupinda padanho rekutanga, iro rinosanganisira pre{0}kudonha, main degreasing, uye surface conditioning. Kunyanya kumatunhu ekuchamhembe, kudzora tembiricha panguva huru yekudonha kwakakosha-kudzika kwetembiricha kuchakanganisa kurapwa; saka, matanho anodiwa ekudzivirira anofanira kutorwa.
◆ Preheating Stage: Mushure mekugadzirisa, mabhodhoro egirazi anopinda muchikamu chekutanga, kazhinji anogara 8 kusvika kumaminitsi e10. Munguva iyi, kuve nechokwadi chekuti mabhodhoro egirazi anochengeta humwe huwandu hwekupisa kwasara usati wapinda mukamuri yekuputira hupfu zvinobudirira kunowedzera hupfu hwekunamatira, nekudaro kunatsiridza kunaka kwekupfapfaidza.
◆ Dust Removal and Cleaning Stage: Iyi nhanho yakakosha kune yakapfapfaidzwa workpieces ine yakakwira process zvinodiwa. Kana iyo workpiece yepamusoro ichishambadza huwandu hwakawanda hweguruva, chigadzirwa chakapedzwa chichava nekusachena, kunokanganisa zvakanyanya kunaka kwepasi.
◆ Powder Coating Stage: Nheyo yeiyi nhanho iri muunyanzvi hwokugadzira hupfu hwehupfu. Yakanakisa tekinoroji ndiyo kiyi yekuve nechokwadi chemhando yepamusoro; saka, kushandisa vashandi vane ruzivo mari inobudirira mukuvandudza chigadzirwa chemhando.
◆ Kuomesa Danho: Muchikamu chino, kupisa kwekuoma uye nguva yekubika kunofanira kunyatsodzorwa. Iyo yakanyanya kuomeswa tembiricha yehupfu inowanzo pakati pe180 dhigirii uye 200 dhigirii, asi chaiyo tembiricha inoda kugadziridzwa zvinoenderana nehunhu hwegirazi zvinhu. Zvichakadaro, chinhambwe chiri pakati pehovhoni yekuomesa nekamuri yekuputira hupfu haifanire kunge iri kure, kazhinji kutenderedza 6 metres, kuve nechokwadi chekuenderera mberi.
