Magalimoto a cab electrophoresis kupanga mzere
Kupenta kwa electrophoretic nthawi zambiri kumaphatikizapo njira zinayi panthawi imodzi
1. Electrophoresis: pansi pa mphamvu yamagetsi yachindunji, ma colloidal particles abwino ndi oipa amaperekedwa ku negative, mayendedwe abwino, omwe amadziwikanso kuti kusambira.
2. Electrolysis: njira yochepetsera makutidwe ndi okosijeni imachitika pa elekitirodi, koma chodabwitsa cha okosijeni ndi kuchepetsa chimapangidwa pa elekitirodi.
3.Electrodeposition: chifukwa electrophoresis, mlandu colloidal particles anasamukira ku anode pafupi Chinsinsi thupi anamasulidwa ma elekitironi, ndi insoluble mafunsidwe, mpweya chodabwitsa, pa nthawi filimu utoto anapanga.
4. Electroosmosis: pansi pa mphamvu ya magetsi, gawo lolimba silisuntha, koma gawo lamadzimadzi limayenda modabwitsa.Electroosmosis imapangitsa kuti madzi omwe ali mufilimuyi atulutsidwe pang'onopang'ono kunja kwa filimuyo, ndipo potsirizira pake amapanga filimu ya utoto wandiweyani yokhala ndi madzi otsika kwambiri komanso kukana kwakukulu, komwe sikungathe kudutsa panopa.
5. Red iron okusayidi epoxy electrophoretic utoto, mwachitsanzo: utoto electrophoretic ndi kusinthidwa epoxy utomoni, butanol ndi Mowa amine, talcum ufa, red iron okusayidi zinthu zikuchokera, electrophoresis utoto kusakaniza ndi madzi osungunuka, pansi pa mphamvu ya dc munda, amene analekanitsidwa. mu cationic ndi anionic zabwino, zoyimbidwa molakwika komanso mndandanda wazinthu zovuta za colloidal chemistry, chemistry yamagetsi electrochemical process.
Njira zokutira za electrophoretic ndi luso
1. Electrophoretic zokutira pazitsulo zonse zachitsulo, njira yake ndi: kuyeretsa kusanachitike → pa intaneti → kuchotsa mafuta → kutsuka → kuchotsa dzimbiri → kutsuka → kusokoneza → kuchapa → phosphating → kuchapa → passivation → zokutira zamagetsi → kuyeretsa mu thanki → kutsuka kopitilira muyeso → kuyanika → popanda intaneti.
2. Gawo lapansi ndi pretreatment ya zokutira zimakhudza kwambiri filimu yokutira ya electrophoretic.Castings nthawi zambiri amagwiritsa ntchito sandblasting kapena kuwombera mfuti kuchotsa dzimbiri, ndi thonje thonje kuchotsa fumbi akuyandama pamwamba pa workpiece, ndi 80# ~ 120# mchenga pepala kuchotsa yotsalira kuwombera zitsulo ndi sundries pamwamba.Pamwamba pazitsulo amachiritsidwa ndi kuchotsa mafuta ndi kuchotsa dzimbiri.Pamene zofunikira zapamtunda ndizokwera kwambiri, mankhwala a phosphating ndi passivation amatha kuchitidwa.Ferrous zitsulo workpiece ayenera phosphating pamaso anodic electrophoresis, apo ayi kukana dzimbiri filimu utoto ndi osauka.Phosphating mankhwala, ambiri kusankha nthaka mchere phosphating filimu makulidwe a 1 ~ 2μm, kumafuna zabwino ndi yunifolomu crystallization wa phosphating filimu.
3. Mu kusefera kachitidwe, kugwiritsa ntchito kwambiri fyuluta, zosefera za kapangidwe ka thumba la mauna, kabowo ka 25 ~ 75μm.Utoto wa electrophoretic umasefedwa kudzera pa mpope woyima kupita ku fyuluta.Poganizira zinthu monga nthawi yosinthira komanso mtundu wafilimu, thumba la fyuluta lomwe lili ndi kabowo 50μm ndilobwino kwambiri.Iwo sangakhoze kokha kukwaniritsa zofunika khalidwe filimu, komanso kuthetsa vuto blockage wa fyuluta thumba.
4. Kuchuluka kwa ma electrophoretic ❖ kuyanika kumakhudza mwachindunji kukhazikika kwamadzi osamba komanso mtundu wa filimu ya utoto.Ndi kuchuluka kwa ma circulation, mpweya ndi kuwira mu thanki zimachepa.Komabe, kukalamba kwa thanki kumafulumizitsa, kugwiritsa ntchito mphamvu kumawonjezeka, ndipo kukhazikika kwa thanki kumakhala koipitsitsa.Ndikwabwino kuwongolera kuchuluka kwa madzi a tanki 6 ~ 8 nthawi / h, osati kutsimikizira mtundu wa filimu ya utoto, komanso kuonetsetsa kuti madzi a tanki akuyenda bwino.
5.Ndi kutalika kwa nthawi yopanga, kusokoneza kwa anode diaphragm kumawonjezeka, ndipo mphamvu yogwira ntchito idzachepa.Chifukwa chake, malinga ndi kutayika kwa voteji popanga, voteji yogwira ntchito yamagetsi iyenera kukulitsidwa pang'onopang'ono kubwezera kutsika kwa voteji ya anode diaphragm.
6.Ultrafiltration system imayang'anira kuchuluka kwa ayoni odetsedwa omwe amabweretsedwa mu chogwirira ntchito kuti awonetsetse kuti zokutira zili bwino.Pogwiritsira ntchito dongosololi, chidwi chiyenera kulipidwa pakugwira ntchito kosalekeza kwa dongosolo pambuyo pa opaleshoni, ntchito yosalekeza imaletsedwa kuti iteteze kuyanika kwa nembanemba ya ultrafiltration.Utoto wouma ndi pigment zimamamatira ku nembanemba ya ultrafiltration ndipo sungathe kutsukidwa bwino, zomwe zingakhudze kwambiri permeability ndi moyo wautumiki wa nembanemba ya ultrafiltration.Madzi amadzimadzi a nembanemba ya ultrafiltration amachepa ndi nthawi yothamanga, ndipo amayenera kutsukidwa kamodzi kwa masiku 30 mpaka 40 kuti awonetsetse kuti madzi akuchulukirachulukira ofunikira pobowoleza ndi kuchapa.
7. Njira yokutira ya electrophoretic ndiyoyenera mizere yambiri yopanga.Kuzungulira kwa thanki ya electrophoresis kuyenera kukhala kosakwana miyezi itatu.Kutenga mzere wopangira ma electrophoresis wokhala ndi mphete zachitsulo zokwana 300,000 mwachitsanzo, ndikofunikira kwambiri kuyendetsa mwasayansi madzi a tanki.Magawo osiyanasiyana amadzimadzi amadzimadzi amayesedwa pafupipafupi, ndipo tanki yamadzimadzi imasinthidwa ndikusinthidwa malinga ndi zotsatira za mayeso.Nthawi zambiri, magawo amadzimadzi amadzimadzi amayezedwa pafupipafupi: PH mtengo, olimba komanso ma conductivity a electrophoresis yankho, ultrafiltration ndi ultrafiltration kuyeretsa njira, cathode (anode) madzi, kuzunguliza kutsuka njira ndi deionized kuyeretsa njira kamodzi patsiku;Chiŵerengero cha nkhope, organic zosungunulira, labotale yaying'ono tank mayeso kawiri pa sabata.
8. Ubwino wa kasamalidwe filimu utoto, nthawi zambiri fufuzani yunifolomu ndi makulidwe a filimu, maonekedwe sayenera pinnhole, otaya, lalanje peel, makwinya ndi zochitika zina, nthawi zonse fufuzani adhesion filimu, kukana dzimbiri ndi zina zakuthupi ndi. zizindikiro za mankhwala.Kuyendera molingana ndi momwe wopanga amayendera, nthawi zambiri gawo lililonse liyenera kuyesedwa.
Kugwiritsa ntchito zokutira kwa electrophoretic ndi utoto wopangidwa ndi madzi kukuwonetsa kupita patsogolo kwamakampani opanga zokutira.
Electrophoretic ❖ kuyanika yomanga liwiro, zimango ndi zochita zokha angathe anazindikira, mosalekeza ntchito, kuchepetsa ntchito kwambiri, yunifolomu utoto filimu, amphamvu adhesion, pakuti ambiri ❖ kuyanika njira si zophweka yokutidwa kapena zida yokutidwa molakwika, monga nthiti tatchulazi, welds. ndi malo ena akhoza kupeza ngakhale, yosalala utoto filimu.Kugwiritsa ntchito utoto mpaka 90% -95%, chifukwa utoto wa electrophoretic ndi water monga zosungunulira, zosapsa, zopanda poizoni, zosavuta kugwiritsa ntchito ndi zina zabwino.Kanema wa utoto wowumitsa wa Electrophoretic, wokhala ndi zomatira bwino, kukana dzimbiri, kukana kwa dzimbiri, kukana nyengo ndi zinthu zina ndizabwino kuposa utoto wamba ndi njira yomangira wamba.
Amagwiritsidwa ntchito pamitundu yonse ya zojambula za workpiece, zitsanzo zina zimatha kusinthidwa.

Njira yopangira mankhwala opangira utsi
Kukonzekera koyambira kumaphatikizapo kupukuta (kuchotsa mafuta), kuchotsa dzimbiri, kupukuta magawo atatu.Phosphating ndi ulalo chapakati, degreasing ndi dzimbiri kuchotsa ndi kukonzekera ndondomeko pamaso phosphating, kotero kupanga mchitidwe, sitiyenera kutenga phosphating ntchito monga cholinga, komanso kuyambira zofunika phosphating khalidwe, kuchita ntchito yabwino kuwonjezera pa. mafuta ndi dzimbiri kuchotsa, makamaka kulabadira kukopana pakati pawo....
