Khadka wax soo saarka cabbista baabuurta ee electrophoresis
Rinjiyeynta korantada guud ahaan waxay ku lug leedahay afar hab oo isku mar ah
1. Electrophoresis: hoos ficilka duurka korantada ee tooska ah, walxaha kolloidalka ah ee togan iyo kuwa taban ee dhaqdhaqaaqa jihada xun, sidoo kale loo yaqaan dabaasha.
2. Electrolysis: falcelinta dhimista oksaydhka ayaa lagu sameeyaa korantada, laakiin ifafaalaha dhimista iyo hoos u dhigista ayaa ku sameysma korantada.
3.Electrodeposition: ay sabab u tahay electrophoresis, qaybaha colloidal eeday u dhaqaaqay anode u dhow template jirka jidhka ka sii daayay electrons, iyo dhigaalka aan milmi lahayn, ifafaale roobab, waqtigan filimka rinjiga sameeyay.
4. Electroosmosis: hoos ficilka beer koronto, wejiga adag ma dhaqaaqo, laakiin wajiga dareeraha dhaqaaqo ifafaale.Electroosmosis waxay sababtaa in biyaha ku jira filimka rinjiga si tartiib tartiib ah loogu sii daayo dibadda filimka, ugu dambeyntiina wuxuu sameeyaa filim rinji cufan oo leh biyo aad u hooseeya iyo iska caabin badan, kaas oo si dhib leh uga gudbi kara hadda.
5. Rinjiga electrophoretic ee birta cas ee epoxy, tusaale ahaan: rinjiga electrophoretic waa resin epoxy ah oo wax laga beddelay, butanol iyo ethanol amine, budada talcum, walxaha oxide birta cas, rinjiga electrophoresis wuxuu isku daraa biyo nadiif ah, iyadoo saameynaysa garoonka dc, kaas oo la kala soocay. galay cationic iyo anionic si togan u eedeeyay, si xun u eedeeyay iyo taxane ah kiimiko colloidal adag, kiimiko jidheed habka elektiroonigga ah.
Hababka iyo xirfadaha dahaarka Electrophoretic
1. Daahan Electrophoretic ee dusha birta guud, nidaamkeedu waa: pre-nadiifinta → on-line → degreasing → dhaqidda → ka saarida miridhku → dhaqidda → dhexdhexaad ah → dhaqidda → fosfat → dhaqidda → passivation → daahan electrophoretic → nadiifinta gudaha → ultra-filtration dhaqid → qallajin → offline.
2. Substrate-ka iyo ka-hortagga dahaarka ayaa saameyn weyn ku leh filimka daahan electrophoretic.Tuubbooyinka guud ahaan waxay isticmaalaan ciid-qarxinta ama qarxinta toogashada si looga saaro miridhku, oo leh dunta cudbi si ay uga saarto siigada dul sabaynaysa dusha shaqada, oo leh 80# ~ 120# warqad ciid ah si ay meesha uga saarto toogashada birta ee hadhaaga ah iyo noocyo kale oo dusha sare ah.Dusha sare ee birta waxaa lagu daaweeyaa saarista saliidda iyo ka saarida miridhku.Marka shuruudaha dusha sare ay aad u sarreeyaan, fosfooraska iyo daaweynta dusha sare ee passivation ayaa la samayn karaa.Birta birta ah ee birta ah waa inay ahaataa fosfat ka hor inta aan la isticmaalin electrophoresis anodic, haddii kale iska caabinta daxalka ee filimka rinjiga waa mid liita.Daaweynta fosfatinta, guud ahaan dooro filimka fosfatinta cusbada ee zinc, dhumucdiisuna tahay 1 ~ 2μm, waxay u baahan tahay si fiican oo isku mid ah crystallization filimka fosfitinta.
3. Nidaamka sifaynta, isticmaalka guud ee shaandhada, shaandhaynta qaab dhismeedka bacda mesh, daloolka 25 ~ 75μm.Rinjiga korantada waxaa lagu sifeeyaa bam toosan oo la shaandheeyo.Iyadoo la tixgelinayo arrimaha sida xilliga beddelka iyo tayada filimka, bacda shaandhada leh 50μm aperture ayaa ugu fiican.Ma buuxin karto oo keliya shuruudaha tayada filimka, laakiin sidoo kale waxay xallin kartaa dhibaatada xannibaadda ee bacda shaandhada.
4. Tirada wareegga ee nidaamka daahan electrophoretic si toos ah u saameeyaa xasilloonida dareeraha qubeyska iyo tayada filimka rinjiga.Kordhinta wareegga wareegga, roobka iyo xumbo ku jira haanta ayaa hoos u dhacda.Si kastaba ha ahaatee, da'da taangiga ayaa la dedejiyaa, isticmaalka tamarta ayaa kordha, xasilloonida taangiga ayaa sii xumaanaysa.Waxay ku habboon tahay in la xakameeyo tirada wareegga wareegga dareeraha taangiga 6 ~ 8 jeer / h, ma aha oo kaliya in la hubiyo tayada filimka rinjiga, laakiin sidoo kale si loo hubiyo hawlgalka xasilloon ee dareeraha taangiga.
5.Kordhinta wakhtiga wax-soo-saarka, xannibaadda diaphragm-ka anode-ka ayaa kordhin doonta, tamarta shaqada ee waxtarka leh ayaa hoos u dhigi doonta.Sidaa darteed, marka loo eego lumitaanka danab ee wax soo saarka, tamarta shaqada ee tamarta korontada waa in si tartiib tartiib ah loo kordhiyo si loo magdhabo dhibicda korantada ee diaphragm anode.
6.Nidaamka Ultrafiltration wuxuu xakameynayaa diiradda ions wasakhda ah ee la keeno workpiece si loo hubiyo tayada daahan.Hawlgalka nidaamkan, waa in fiiro gaar ah loo yeesho hawlgalka joogtada ah ee nidaamka ka dib hawlgalka, hawlgalka joojinta si adag ayaa loo mamnuucay si looga hortago qalajinta xuubka ultrafiltration.Xabagta la qalajiyey iyo midabka ayaa ku dheggan xuubka ultrafiltration oo si fiican looma nadiifin karo, taas oo si dhab ah u saameyn doonta qulqulka iyo nolosha adeegga xuubka ultrafiltration.Heerka dheecaanka xuubka ultrafiltration wuxuu hoos u dhacaa marka uu socdo wakhtiga, waana in la nadiifiyaa hal mar 30 ilaa 40 maalmood si loo hubiyo biyaha ultrafiltration ee looga baahan yahay dheecaanka iyo dhaqidda.
7. Habka dahaarka Electrophoretic wuxuu ku habboon yahay tiro badan oo khadadka wax soo saarka.Wareegga beddelka taangiga electrophoresis waa inuu ka yaraado 3 bilood.Qaadashada khadka wax soo saarka ee electrophoresis oo leh wax soo saar sanadle ah oo ah 300,000 siddo bir ah tusaale ahaan, aad bay muhiim u tahay in si cilmiyeysan loo maareeyo dareeraha haanta.Qaybaha kala duwan ee dareeraha haanta si joogto ah ayaa loo tijaabiyaa, dareeraha haantana waa la hagaajiyaa oo la beddelaa iyadoo loo eegayo natiijooyinka baaritaanka.Guud ahaan, xuduudaha dareeraha taangiga waxaa lagu qiyaasaa inta jeer ee soo socota: qiimaha PH, content adag iyo conductivity of electrophoresis xal, ultrafiltration iyo ultrafiltration xal nadiifinta, cathode (anode) dareere, wareegga wareegga xal dhaqidda iyo deionized xal nadiifinta deionized maalintii hal mar;Saamiga saldhigga wejiga, waxa ku jira dareeraha organic, shaybaarka tijaabada haanta yar ee laba jeer todobaadkii.
8. Tayada maaraynta filimka rinjiga, waa in inta badan la hubiyo isku midka ah iyo dhumucda filimka, muuqaalku waa inuusan haysanin godka, qulqulka, diirka liinta, laalaabyada iyo ifafaale kale, si joogto ah u hubi dhejinta filimka, iska caabinta daxalka iyo kuwa kale ee jirka iyo tilmaamayaasha kiimikada.Wareegga kormeerka iyadoo loo eegayo heerarka baadhista soo saaraha, guud ahaan qayb kasta waa in la tijaabiyaa.
Codsiga daahan elektiroonigga ah iyo rinjiga biyaha ka dhasha ayaa calaamad u ah horumarka weyn ee warshadaha daahan.
Daahan Electrophoretic xawaaraha dhismaha, makaanization iyo automation waa la xaqiijin karaa, hawlgal joogto ah, hoos u xoojinta shaqada, film rinjiga labiska, adhesion xoog leh, waayo, habka daahan guud ma fududa in la dahaarka ah ama qaybaha xun dahaarka ah, sida feeraha kor ku xusan, alxanka. iyo meelaha kale waxay heli karaan xitaa, filim rinji siman.Heerka isticmaalka rinjiga ilaa 90% -95%, sababtoo ah rinjiga elektrophoretic waa water sida dareere ah, aan guban karin, aan sun ahayn, fududahay in la shaqeeyo iyo faa'iidooyin kale.Electrophoretic film rinji qalajinta, oo leh dhejis heer sare ah, caabbinta miridhku, caabbinta daxalka, caabbinta cimilada iyo guryaha kale ayaa ka fiican rinjiga caadiga ah iyo habka dhismaha guud.
Loo isticmaalo dhammaan noocyada rinjiyeynta workpiece, moodooyinka kale waa la beddeli karaa.

buufin nooca pretreatment line wax soo saarka
Dahaarka ka hor daawaynta waxaa ka mid ah hoos u dhigista (degreasing), ka saarida miridhku, fosfitinta saddex qaybood.Phosphating waa isku xirka dhexe, hoos u dhigista iyo ka saarista miridhku waa habka diyaarinta ka hor fosfatinta, sidaas darteed dhaqanka wax soo saarka, waa in aan kaliya qaadan shaqada fosfatinta sida diiradda, laakiin sidoo kale ka bilow shuruudaha tayada fosfooraska, samee shaqo wanaagsan marka lagu daro saliidda iyo miridhku ka saarista, gaar ahaan fiiro gaar ah u leh saamaynta wadaagga ah ee ka dhexeeya....
