Umgca wokuvelisa i-Automobile cab electrophoresis
Ipeyinti ye-Electrophoretic ngokubanzi ibandakanya iinkqubo ezine ngaxeshanye
1. I-Electrophoresis: phantsi kwesenzo sentsimi yombane yangoku, i-colloidal ene-charge kunye ne-negative particles ukuya kwi-negative, direction movement movement, eyaziwa ngokuba yi-swimming.
2. I-Electrolysis: ukusabela kokunciphisa i-oxidation kuqhutyelwa kwi-electrode, kodwa i-oxidation kunye nokunciphisa i-phenomenon yenziwa kwi-electrode.
3.I-Electrodeposition: ngenxa ye-electrophoresis, amasuntswana e-colloidal ahlawulweyo afudukela kwi-anode kufutshane nomzimba wetemplate okhutshwe ii-electron, kunye ne-insoluble deposition, i-precipitation phenomenon, ngeli xesha ifilimu yepeyinti yenziwa.
4. I-Electroosmosis: phantsi kwesenzo sommandla wombane, isigaba esiqinileyo asishukumi, kodwa isigaba se-liquid sihambisa i-phenomenon.I-Electroosmosis ibangela ukuba umxholo wamanzi kwifilimu yepeyinti ukhutshwe ngokuthe ngcembe ngaphandle kwefilimu, kwaye ekugqibeleni wenze ifilimu yepeyinti eshinyeneyo enomxholo ophantsi kakhulu wamanzi kunye nokumelana okuphezulu, okungenakukwazi ukudlula ngoku.
5. Ipeyinti ebomvu ye-iron oxide epoxy electrophoretic peyinti, umzekelo: ipeyinti ye-electrophoretic yi-epoxy resin eguquliweyo, i-butanol kunye ne-ethanol amine, i-talcum powder, i-iron oxide ebomvu, i-electrophoresis peyinti ixutywa namanzi adiyiweyo, phantsi kwempembelelo yentsimi ye-dc, eyahlulwayo. kwi-cationic echajiwe kakuhle kunye ne-anionic, ityala elibi kunye nochungechunge lwekhemikhali ye-colloidal enzima, inkqubo ye-electrochemical chemistry.
Iindlela zokwaleka kwe-Electrophoretic kunye nezakhono
1. I-Electrophoretic yokugquma kumphezulu wentsimbi jikelele, inkqubo yayo yile: ukucocwa kwangaphambili → kwi-intanethi → ukukhupha igrisi → ukuhlamba → ukususwa komhlwa → ukuhlamba → ukungathathi hlangothi → ukuhlamba → phosphating → ukuhlamba → ukugqitha → ukucocwa kwe-electrophoretic → ukucocwa kwetanki → ukuhlanjwa kwe-ultra-filtration → ukomisa → ngaphandle kweintanethi.
2. I-substrate kunye nokulungiswa kwangaphambili kwengubo kunempembelelo enkulu kwifilimu yokugqoka i-electrophoretic.Iisanti ngokubanzi zisebenzisa ukuqhushumba kwesanti okanye ukudutyulwa kokususa umhlwa, ngomsonto womqhaphu ukususa uthuli oludadayo kumphezulu wendawo yokusebenza, ngephepha lesanti le 80# ~ 120# ukususa intsalela yentsimbi kunye nezinye iisundries kumphezulu.Umphezulu wensimbi uphathwa ngokususa ioli kunye nokususwa kwe-rust.Xa iimfuno zomphezulu ziphezulu kakhulu, i-phosphating kunye ne-passivation yonyango yendawo inokuqhutywa.Intsimbi yokusebenza yentsimbi kufuneka ibe yiphosphating phambi kwe-anodic electrophoresis, kungenjalo ukunyameka kokutya kwefilimu yepeyinti kubi.Unyango lwe-Phosphating, ngokubanzi khetha ifilimu ye-zinc yetyuwa ye-phosphating, ubukhulu obumalunga ne-1 ~ 2μm, ifuna i-crystallization ecocekileyo kunye neyunifomu yefilimu ye-phosphating.
3. Kwinkqubo yokuhluza, ukusetyenziswa ngokubanzi kwesihluzi, icebo lokucoca ukwakhiwa kwengxowa yomnatha, ukuvuleka kwe-25 ~ 75μm.Ipeyinti ye-Electrophoretic ihluzwa ngempompo eme nkqo ukuya kwisihluzo.Ukuqwalasela izinto ezifana nexesha lokutshintshwa kunye nomgangatho wefilimu, isikhwama sokucoca nge-aperture 50μm yeyona nto ingcono.Ayinakuhlangabezana kuphela neemfuno zomgangatho wefilimu, kodwa iphinde isombulule ingxaki yokuvalwa kwengxowa yokucoca.
4. Ubuninzi bokujikeleza kwenkqubo yokugqoka i-electrophoretic ichaphazela ngokuthe ngqo ukuzinza kolwelo lokuhlambela kunye nomgangatho wefilimu yepeyinti.Ngokunyuka kokujikeleza, imvula kunye ne-bubble kwitanki iyancipha.Nangona kunjalo, ukuguga kwetanki kukhawuleza, ukusetyenziswa kwamandla kwanda, kwaye ukuzinza kwetanki kuba kubi.Kukulungele ukulawula inani lokujikeleza kwetanki engama-6 ~ 8 amaxesha / h, kungekuphela nje ukuqinisekisa umgangatho wefilimu yepeyinti, kodwa nokuqinisekisa ukusebenza okuzinzile kwe-tank liquid.
5.Ngokwandiswa kwexesha lokuvelisa, i-impedance ye-anode diaphragm iya kwanda, kwaye i-voltage esebenzayo iya kuncipha.Ke ngoko, ngokwelahleko yombane kwimveliso, amandla ombane osebenzayo obonelelo lwamandla kufuneka anyuswe kancinci kancinci ukuhlawulela ukuhla kombane we-anode diaphragm.
6.Inkqubo ye-Ultrafiltration ilawula ukuxinwa kwee-ion zokungcola eziswe kwindawo yokusebenza ukuze kuqinisekiswe umgangatho wokugquma.Ekusebenzeni kwale nkqubo, ingqalelo kufuneka ihlawulwe ekusebenzeni ngokuqhubekayo kwenkqubo emva kokusebenza, umsebenzi ongapheliyo unqatshelwe ngokungqongqo ukukhusela ukoma kwe-membrane ye-ultrafiltration.I-resin eyomileyo kunye ne-pigment ibambelela kwi-membrane ye-ultrafiltration kwaye ayikwazi ukucocwa ngokucokisekileyo, eya kuchaphazela kakhulu ukugqithiswa kunye nobomi benkonzo ye-membrane ye-ultrafiltration.Isantya samanzi e-membrane ye-ultrafiltration siyancipha ngexesha lokuhamba, kwaye kufuneka icocwe kube kanye ngeentsuku ezingama-30 ukuya kwezingama-40 ukuze kuqinisekiswe ukuba amanzi acocekileyo afunekayo ekutshiseni nasekuhlambeni.
7. Indlela yokugqoka i-Electrophoretic ifanelekile kwinani elikhulu lemigca yokuvelisa.Umjikelo wokutshintshwa kwetanki ye-electrophoresis kufuneka ube ngaphantsi kweenyanga ezi-3.Ukuthatha umgca wokuvelisa i-electrophoresis kunye nemveliso yonyaka yeentsimbi ze-300,000 njengomzekelo, kubaluleke kakhulu ukulawula ngokwesayensi i-tank liquid.Iiparamitha ezahlukeneyo zolwelo lwetanki zivavanywa rhoqo, kwaye ulwelo lwetanki luhlengahlengiswa kwaye lutshintshwe ngokweziphumo zovavanyo.Ngokuqhelekileyo, iiparamitha zetanki yamanzi zilinganiswa ngokuphindaphindiweyo: ixabiso le-PH, umxholo oqinileyo kunye ne-conductivity yesisombululo se-electrophoresis, isisombululo sokucoca i-ultrafiltration kunye ne-ultrafiltration, i-cathode (anode) yamanzi, isisombululo sokuhlamba esijikelezayo kunye nesisombululo sokucoca i-deionized kanye ngosuku;Ubungakanani besiseko sobuso, umxholo we-organic solvent, i-laboratory yovavanyo lwetanki encinci kabini ngeveki.
8. Umgangatho wolawulo lwefilimu yepeyinti, kufuneka uhlale ujonge ukufana kunye nobukhulu befilimu, ukubonakala akufanele kube ne-pinhole, ukuhamba, i-orenji, imibimbi kunye nezinye izinto, jonga rhoqo ukunamathela kwefilimu, ukuxhathisa ukubola kunye nezinye izinto ezibonakalayo kunye nezinye izinto. izalathisi zeekhemikhali.Umjikelo wokuhlola ngokwemigangatho yokuhlola yomenzi, ngokubanzi indawo nganye kufuneka ivavanywe.
Ukusetyenziswa kwe-electrophoretic coating kunye nepeyinti ephuma emanzini ibonisa inkqubela phambili enkulu kwishishini lokugqoka.
Isantya sokwakhiwa kwe-Electrophoretic coating, umatshini kunye ne-automation inokufezekiswa, ukusebenza ngokuqhubekayo, ukunciphisa ukuqina kwabasebenzi, ifilimu yepeyinti efanayo, ukuncamathela okuqinileyo, kuba indlela yokwaleka ngokubanzi akulula ukuyityabeka okanye iindawo ezigqunywe kakubi, ezifana nezi mbambo zikhankanywe ngasentla, iiwelds. kunye nezinye iindawo zinokulingana, ifilimu yepeyinti egudileyo.Izinga lokusetyenziswa kwepeyinti ukuya kuma-90% -95%, kuba ipeyinti ye-electrophoretic is water njengesinyibilikisi, esingenakutsha, esingenatyhefu, kulula ukusebenza kunye nezinye iingenelo.Ifilimu yepeyinti yokumisa i-Electrophoretic, enamathele ngokugqwesileyo, ukumelana kwayo nomhlwa, ukuxhathisa ukubola, ukumelana nemozulu kunye nezinye iimpawu zingcono kunepeyinti eqhelekileyo kunye nendlela yokwakha ngokubanzi.
Isetyenziselwa zonke iintlobo zepeyinti yomsebenzi, ezinye iimodeli zinokwenziwa ngokwezifiso.
Iimveliso ezinxulumeneyo

Uhlobo lokutshiza umgca wemveliso yonyango lwangaphambili
Ukutyalwa kwangaphambili kokutyabeka kubandakanya ukuthambisa (ukunciphisa), ukususwa komhlwa, ukuphosphotha amacandelo amathathu.I-Phosphating yikhonkco eliphakathi, ukuchithwa kunye nokususwa kwe-rust yinkqubo yokulungiselela ngaphambi kokuba i-phosphating, ngoko ekusebenzeni kwemveliso, akufanele sithathe kuphela umsebenzi we-phosphating njengento ekugxilwe kuyo, kodwa kwakhona siqale kwiimfuno zomgangatho we-phosphating, senze umsebenzi omhle ukongeza ukususwa kweoli kunye nomhlwa, ngokukodwa ingqalelo kwimpembelelo efanayo phakathi kwabo....
