Mohala oa tlhahiso ea koloi ea cab electrophoresis
Pente ea electrophoretic ka kakaretso e kenyelletsa lits'ebetso tse 'ne ka nako e le ngoe
1. Electrophoresis: tlas'a ts'ebetso ea motlakase oa motlakase oa hona joale, likaroloana tse ntle le tse mpe tsa colloidal ho ea ho motsamao o fosahetseng, o motle, o tsejoang hape e le ho sesa.
2. Electrolysis: karabelo ea phokotso ea oxidation e etsoa ka eleketrode, empa ts'ebetso ea oxidation le phokotso e thehoa holim'a electrode.
3.Electrodeposition: ka lebaka la electrophoresis, le qosoa colloidal likaroloana fallela ho anode haufi thempleite holim 'mele lokolloa dieleketerone, le insoluble deposition, precipitation phenomenon, ka nako ena filimi pente thehoa.
4. Electroosmosis: tlas'a ts'ebetso ea sebaka sa motlakase, karolo e tiileng ha e sisinyehe, empa karolo ea metsi e tsamaisa ntho e makatsang.Electroosmosis e etsa hore metsi a filimi ea pente a tsoe butle-butle ho ea ka ntle ho filimi, 'me qetellong a thehe filimi e teteaneng ea pente e nang le metsi a fokolang haholo le ho hanyetsa ho phahameng, ho ke keng ha khoneha ho feta hona joale.
5. Pente e khubelu ea iron oxide epoxy electrophoretic pente, mohlala: pente ea electrophoretic ke epoxy resin e fetotsoeng, butanol le ethanol amine, talcum powder, red iron oxide material composition, pente ea electrophoresis e kopanya le metsi a silafetseng, tlas'a phello ea tšimo ea dc, e arohaneng. ho cationic le anionic e qosoang hantle, e qosoa hampe le letoto la lik'hemik'hale tse rarahaneng tsa colloidal, chemistry ea electrochemical process.
Mekhoa le bokhoni ba ho roala ka electrophoretic
1. Ho roala ka electrophoretic ka holim'a tšepe e akaretsang, ts'ebetso ea eona ke: ho hloekisa pele → inthaneteng → ho hloekisoa → ho hlatsoa → ho tlosa mafome → ho hlatsoa → ho tlosa mafome → ho se nke lehlakore → ho hlatsoa → phosphating → ho hlatsuoa → ho hloekisoa → ho hloekisa ka har'a tanka → ho hlatsoa ka ho feletseng. → ho omisa → kantle ho marang-rang.
2. Substrate le pretreatment ea ho roala li na le tšusumetso e kholo filiming ea ho roala electrophoretic.Hangata li-castings li sebelisa ho phatloha ha lehlabathe kapa ho thunya bakeng sa ho ntša mafome, ka khoele ea k'hothone ho tlosa lerōle le phaphametseng holim'a sebaka sa mosebetsi, ka pampiri ea lehlabathe ea 80# ~ 120# ho tlosa lithunya tse setseng tsa tšepe le lintho tse ling tse holimo.Sebaka sa tšepe se tšoaroa ka ho tlosoa ha oli le ho tlosoa ha mafome.Ha litlhoko tsa bokaholimo li le holimo haholo, kalafo ea phosphating le passivation e ka etsoa.Ferrous metal workpiece e lokela ho ba phosphating pele anodic electrophoresis, ho seng joalo ho hanyetsa kutu ea filimi ea pente e futsanehile.Phosphating kalafo, ka kakaretso khetha zinki letsoai phosphating filimi, botenya ba ka bang 1 ~ 2μm, hloka e ntle le junifomo crystallization ea phosphating filimi.
3. Sistimi ea ho sefa, tšebeliso e akaretsang ea sefahla, filthara bakeng sa sebopeho sa mokotla oa letlooeng, lesoba la 25 ~ 75μm.Pente ea electrophoretic e tlhotluoa ka pompo e emeng ho ea ho sefe.Ha ho nahanoa ka lintlha tse joalo ka nako ea phetoho le boleng ba filimi, mokotla oa sesefa o nang le aperture 50μm o molemo ka ho fetisisa.E ke ke ea kopana feela le litlhoko tsa boleng ba filimi, empa hape le ho rarolla bothata ba ho thibela mokotla oa mokotla.
4. Palo ea potoloho ea sistimi ea ho roala ka electrophoretic e ama ka kotloloho botsitso ba mokelikeli oa ho hlapa le boleng ba filimi ea pente.Ka keketseho ea potoloho, pula le bubble ka tanka lia fokotseha.Leha ho le joalo, botsofali ba tanka bo potlakisa, tšebeliso ea matla e eketseha, 'me botsitso ba tanka bo mpefala.Ho loketse ho laola palo ea ho potoloha ha metsi a tanka 6 ~ 8 linako / h, eseng feela ho netefatsa boleng ba filimi ea pente, empa hape le ho netefatsa ts'ebetso e tsitsitseng ea metsi a tanka.
5.Ka ho lelefatsa nako ea tlhahiso, tšitiso ea anode diaphragm e tla eketseha, 'me matla a sebetsang a sebetsang a tla fokotseha.Ka hona, ho latela tahlehelo ea motlakase tlhahisong, matla a sebetsang a phepelo ea motlakase a lokela ho eketseha butle-butle ho lefella ho theoha ha voltage ea anode diaphragm.
6.Sistimi ea Ultrafiltration e laola bongata ba li-ion tse sa hloekang tse tlisoang ka har'a sesebelisoa ho netefatsa boleng ba ho roala.Ts'ebetsong ea tsamaiso ena, tlhokomelo e lokela ho lefshoa ts'ebetsong e tsoelang pele ea tsamaiso ka mor'a ts'ebetso, ts'ebetso e sa khaotseng e thibetsoe ka thata ho thibela ho omisoa ha lera la ultrafiltration.Resin e omisitsoeng le pigment e khomarela lera la ultrafiltration 'me e ke ke ea hloekisoa ka ho feletseng, e leng se tla ama ka ho teba ho phunyeletsa le bophelo ba tšebeletso ea lera la ultrafiltration.Sekhahla sa mokelikeli oa lera la ultrafiltration se fokotseha ha nako e ntse e sebetsa, 'me se lokela ho hloekisoa hang ka matsatsi a 30 ho isa ho a 40 e le ho netefatsa hore metsi a hloekileng a hlokehang bakeng sa ho rotha le ho hlatsoa.
7. Mokhoa oa ho roala ka electrophoretic o loketse palo e kholo ea mela ea tlhahiso.Potoloho e ncha ea tanka ea electrophoresis e lokela ho ba tlase ho likhoeli tse 3.Ho nka mohala oa tlhahiso ea electrophoresis ka tlhahiso ea selemo le selemo ea mehele ea tšepe ea 300,000 e le mohlala, ke habohlokoa haholo ho laola metsi a tanka ka saense.Litekanyetso tse fapaneng tsa metsi a tanka li lekoa khafetsa, 'me metsi a tanka a fetoloa ebe a nkeloa sebaka ho latela liphetho tsa liteko.Ka kakaretso, litekanyo tsa metsi a tanka li lekantsoe ka makhetlo a latelang: PH boleng, dikahare tse tiileng le conductivity ea tharollo ea electrophoresis, tharollo ea ultrafiltration le ultrafiltration ea ho hloekisa, mokelikeli oa cathode (anode), ho potoloha ho hlatsoa tharollo le tharollo ea ho hloekisa deionized hang ka letsatsi;Karo-karolelano ea sefahleho, likahare tsa organic solvent, laboratori e nyane ea liteko tsa tanka habeli ka beke.
8. Boleng ba tsamaiso ea filimi ea pente, hangata e lokela ho hlahloba ho tšoana le botenya ba filimi, ponahalo ha ea lokela ho ba le pinhole, phallo, lekhapetla la lamunu, wrinkles le liketsahalo tse ling, kamehla hlahloba ho khomarela filimi, ho hanyetsa kutu le tse ling tsa 'mele le tse ling. lipontšo tsa lik'hemik'hale.Potoloho ea tlhahlobo ho latela maemo a tlhahlobo ea moetsi, ka kakaretso lotho ka 'ngoe e lokela ho lekoa.
Tšebeliso ea ho roala ha electrophoretic le pente e nang le metsi e tšoaea tsoelo-pele e kholo indastering ea ho roala.
Electrophoretic barbotage kaho lebelo, mechine le automation ka hlokomela, tshebetso e tsoelang pele, fokotsa matla a mosebetsi o boima, junifomo pente filimi, ho khomarela ka matla, bakeng sa mokhoa o akaretsang oa ho roala ha ho bonolo ho roala kapa likarolo tse mpe tse koahetsoeng, tse kang likhopo tse boletsoeng ka holimo, li-welds. le libaka tse ling ka fumana esita, boreleli pente filimi.Sekhahla sa tšebeliso ea pente ho fihla ho 90% -95%, hobane pente ea electrophoretic ke water e le mokelikeli, o sa cheng, o se nang chefo, o bonolo ho sebetsa le melemo e meng.Electrophoretic drying pente filimi, e nang le sekhomaretsi se setle, ho hanyetsa mafome, ho hanyetsa kutu, ho hanyetsa boemo ba leholimo le lisebelisoa tse ling li molemo ho feta pente e tloaelehileng le mokhoa o akaretsang oa kaho.
E sebelisoa bakeng sa mefuta eohle ea pente ea mosebetsi, mefuta e meng e ka etsoa ka mokhoa o ikhethileng.
