Zanen Electrophoretic gabaɗaya ya ƙunshi matakai guda huɗu na lokaci ɗaya
1. Electrophoresis: ƙarƙashin aikin filin lantarki na yanzu kai tsaye, ƙwararrun ƙwayoyin colloidal masu inganci da korau zuwa korau, motsi mai kyau, wanda kuma aka sani da iyo.
2. Electrolysis: Ana aiwatar da aikin rage yawan iskar oxygen akan lantarki, amma ana samun iskar oxygen da raguwar sabon abu akan lantarki.
3.Electrodeposition: saboda electrophoresis, da caje colloidal barbashi koma zuwa anode kusa da template surface jiki saki electrons, da insoluble deposition, hazo sabon abu, a wannan lokaci da Paint film kafa.
4. Electroosmosis: ƙarƙashin aikin filin lantarki, ƙaƙƙarfan lokaci ba ya motsawa, amma yanayin ruwa yana motsawa sabon abu.Electroosmosis yana sa abin da ke cikin fim ɗin fenti ya fito a hankali zuwa wajen fim ɗin, kuma a ƙarshe ya samar da fim ɗin fenti mai ƙarancin ruwa da tsayin daka, wanda da wuya ya wuce ta halin yanzu.
5. Red baƙin ƙarfe oxide epoxy electrophoretic Paint, misali: da electrophoretic Paint ne modified epoxy guduro, butanol da ethanol amine, talcum foda, jan ƙarfe oxide abu abun da ke ciki, electrophoresis fenti gauraye da distilled ruwa, a karkashin sakamakon dc filin, da aka rabu. cikin ingantaccen cajin cationic da anionic, caji mara kyau da jerin hadaddun sunadarai na colloidal, tsarin sinadarai ta jiki.
Hanyoyin shafawa da fasaha na Electrophoretic
1. Electrophoretic shafi na janar karfe surface, da tsari ne: pre-tsaftacewa → on-line → degreasing → wanka → tsatsa cire → wanka → neutralization → wanka → phosphating → wanka → passivation → electrophoretic shafi → in-tanki tsaftacewa → matsananci- tacewa wanka → bushewa → layi.
2. Ƙarƙashin ƙwayar cuta da pretreatment na sutura suna da tasiri mai yawa akan fim ɗin murfin electrophoretic.Simintin gyare-gyare gabaɗaya suna amfani da fashewar yashi ko harbin iska don cire tsatsa, tare da zaren auduga don cire ƙura mai iyo a saman kayan aikin, tare da takarda yashi 80 # ~ 120 # don cire ragowar karfen harbi da sauran abubuwa a saman.Ana kula da saman karfe tare da cire mai da cire tsatsa.Lokacin da buƙatun saman sun yi yawa, ana iya aiwatar da phosphating da jiyya na ƙasa.Ferrous karfe workpiece dole ne a phosphating kafin anodic electrophoresis, in ba haka ba da lalata juriya na Paint film ne matalauta.Jiyya na phosphating, gabaɗaya zaɓi fim ɗin gishirin phosphating na zinc, kauri na kusan 1 ~ 2μm, yana buƙatar lafiya da daidaituwa na fim ɗin phosphating.
3. A cikin tsarin tacewa, yawan amfani da tacewa, tace don tsarin jakar raga, buɗewar 25 ~ 75μm.Ana tace fenti na electrophoretic ta famfo a tsaye zuwa tacewa.Yin la'akari da dalilai kamar lokacin maye gurbin da ingancin fim, jakar tacewa tare da budewar 50μm shine mafi kyau.Ba zai iya saduwa da ingancin buƙatun fim kawai ba, amma kuma yana magance matsalar toshewar jakar tacewa.
4. A wurare dabam dabam yawa electrophoretic shafi tsarin kai tsaye rinjayar da kwanciyar hankali na wanka ruwa da kuma ingancin Paint fim.Tare da haɓakar wurare dabam dabam, hazo da kumfa a cikin tanki suna raguwa.Duk da haka, tsufa na tanki yana haɓaka, yawan amfani da makamashi yana ƙaruwa, kuma kwanciyar hankali na tanki ya zama mafi muni.Yana da manufa don sarrafa adadin wurare dabam dabam na tanki ruwa 6 ~ 8 sau / h, ba kawai don tabbatar da ingancin fim ɗin fenti ba, har ma don tabbatar da kwanciyar hankali na aikin tanki.
5.Tare da tsawaita lokacin samarwa, haɓakar diaphragm na anode zai haɓaka, kuma ingantaccen ƙarfin aiki zai ragu.Sabili da haka, bisa ga asarar ƙarfin lantarki a cikin samarwa, aikin wutar lantarki ya kamata a ƙara a hankali don rama raguwar ƙarfin lantarki na diaphragm na anode.
6.Tsarin ultrafiltration yana sarrafa ƙaddamar da ions na ƙazanta da aka kawo a cikin aikin aikin don tabbatar da ingancin sutura.A cikin aikin wannan tsarin, ya kamata a ba da hankali ga ci gaba da aiki na tsarin bayan aiki, an hana dakatar da aiki sosai don hana bushewar membrane na ultrafiltration.Busassun guduro da pigment suna manne da membrane na ultrafiltration kuma ba za a iya tsaftace su sosai ba, wanda zai yi tasiri sosai ga iyawar da rayuwar sabis na membrane na ultrafiltration.Yawan zubar da ruwa na ultrafiltration membrane yana raguwa tare da lokacin gudu, kuma ya kamata a tsaftace shi sau ɗaya na kwanaki 30 zuwa 40 don tabbatar da ruwan ultrafiltration da ake bukata don leaching da wankewa.
7. Hanyar suturar Electrophoretic ta dace da babban adadin layin samarwa.Matsakaicin maye gurbin tankin electrophoresis yakamata ya kasance ƙasa da watanni 3.Ɗaukar layin samar da electrophoresis tare da fitowar kowace shekara na zoben karfe 300,000 a matsayin misali, yana da matukar muhimmanci a kimiyance sarrafa ruwan tanki.Ana gwada sigogi daban-daban na ruwan tanki akai-akai, kuma ana daidaita ruwan tanki da maye gurbinsu bisa ga sakamakon gwajin.Gabaɗaya, ana auna ma'auni na ruwan tanki a cikin mitar mai zuwa: ƙimar PH, ingantaccen abun ciki da haɓakawa na maganin electrophoresis, ultrafiltration da ultrafiltration tsaftacewa bayani, cathode (anode) ruwa, zazzage bayani na wankewa da tsaftacewa mai tsabta sau ɗaya a rana;Face tushe rabo, Organic kaushi abun ciki, dakin gwaje-gwaje kananan tanki gwajin sau biyu a mako.
8. Ingancin sarrafa fim ɗin fenti, sau da yawa ya kamata ya bincika daidaito da kauri na fim ɗin, bayyanar bai kamata ya sami pinhole ba, kwarara, kwasfa na orange, wrinkles da sauran abubuwan mamaki, a kai a kai duba mannewar fim ɗin, juriya na lalata da sauran jiki da sinadaran Manuniya.Zagayowar dubawa bisa ga ka'idodin dubawa na masana'anta, gabaɗaya kowace kuri'a yakamata a gwada.
Aikace-aikacen murfin electrophoretic da fenti na ruwa yana nuna babban ci gaba a masana'antar sutura.
Electrophoretic shafi yi gudun, injiniyoyi da aiki da kai za a iya gane, ci gaba da aiki, rage aiki tsanani, uniform Paint film, karfi mannewa, domin general shafi Hanyar ba sauki a mai rufi ko mugun mai rufi sassa, kamar na sama da aka ambata hakarkarinsa, welds. da sauran wurare na iya samun ma, fim ɗin fenti mai santsi.Yawan amfani da fenti har zuwa 90% -95%, saboda fentin electrophoretic water a matsayin sauran ƙarfi, ba - flammable, mara guba, mai sauƙin aiki da sauran fa'idodi.Electrophoretic bushewa Paint fim, tare da kyau kwarai mannewa, ta tsatsa juriya, lalata juriya, weather juriya da sauran kaddarorin ne mafi alhẽri daga talakawa Paint da kuma general yi hanya.
An yi amfani da shi don kowane nau'in zanen kayan aiki, sauran samfuran za a iya keɓance su.
