Saamaynta conductivity ee daahan electrophoretic
Hab-dhaqanku waa halbeeg-hawleed aad muhiim u ah habka daahanka-cathodic electrophoresis. Waxay leedahay xiriir aad u dhow oo leh awoodda tuurista, waxayna saameyn weyn ku leeyihiin guryaha electrophoretic, xasilloonida dareeraha qubayska iyo saameynta dahaarka. Guud ahaan marka la hadlo, koorsada sare ee qubeyska rinjiga elektrophoresis, dhexgalka sare ee rinjiga wuxuu noqon doonaa; caksigeeda, waa caksi. Sidaa darteed, korantada dareeraha taangiga waa in si adag loo xakameeyaa inta u dhexeysa xeerarka nidaamka. Markaa habka wax soo saarka ballaaran ee daahan electrophoretic, conductivity ee daahan electrophoretic ee saamaynta?
Conductivity waxaa loola jeedaa qadarka conductivity ee fogaanta 1cm ee l sentimitir labajibbaaran ee dusha tiirka, in dhacdooyinka daahan electrophoretic ee taangiga, dareere UF, dareeraha tiirka iyo heerka conductivity loo isticmaalo biyo saafi ah si ay u muujiyaan heerka ay adag tahay conductivity ka, laakiin sidoo kale faa'iido badan iska caabbinta korontada si ay u muujiyaan. Hab-dhaqanku waa is-dhaafsiga iska caabin gaar ah.
Iska caabin gaar ah (Ω - cm) = 6 jeer 10/ habdhaqan, iyo conductivity waxaa lagu cabbiraa μS/cm ama uΩ- cm-1.
conductivity of electrophoretic dareere taangiga rinji la xidhiidha adkaha ah ee dareeraha taangiga, qiimaha pH iyo content ee ions wasakh ah, iwm. Waa mid ka mid ah hababka muhiimka ah ee xuduudaha iyo waa in la xakameeyo gudahood xad gaar ah, size ee kala duwan ku xiran tahay. on noocyada rinji electrophoretic, iyo conductivity hoose ama sare ee dareeraha taangiga ma wanaagsana, taas oo si toos ah u saameyn doona tayada rinjiyeynta electrophoretic.
Saamaynta conductivity ee daahan electrophoretic:
1. Ilaa xad, conductivity go'aamin kara cadadka rinjiga in lagu dabaqi karo workpiece by dabaasha ilaa xad.
2. Dhaqdhaqaaq yar oo yar ayaa yarayn doona qadarka rinjiga cathodic electrophoresis ee la dhigo, liddi ku ah, kororka sare ayaa wax yar kordhin doona qadarka rinjiga electrophoresis ee cathodic ee la dhigo.
3. conductivity dareeraha taangiga waa mid aad u sarreeya ama aad u hooseeya, laakiin sidoo kale on dhumucda filimka rinjiga electrophoresis, muuqaalka, dhexgalka dabaasha, iwm, gaar ahaan la conductivity dareere taangiga kordhay, dhexgalka dabaasha ayaa sidoo kale kordhay, ka dibna waxa ay sidoo kale waa xad. dhumucda filimka dhumuc weyn.
4. conductivity aan caadiga ahayn sare ee slurry waxaa inta badan sababa content wasakh sare ama pH hoose, iyo sidoo kale la socda isbedel aan caadi ahayn ee tayada filimka daahan, sida diirka orange, pinholes, ama ku soo laabtay kala diri ee halis ah . ..... iyo dhacdooyin kale oo aan caadi ahayn. Waxay u baahan tahay in lagu maamulo ultrafilter oo leh nidaam anode ah.
Hordhaca kor ku xusan waa hab-dhaqanka katoodic electrophoresis rinjiyeynta qaar ka mid ah saamaynta. Guud ahaan, conductivity kaamerada waa in lagu xakameeyo gudahood xadka 1200 ± 300μs / cm, sababtoo ah conductivity inta badan ku tiirsan tayada biyaha deionized ka hor electrophoresis iyo cusboonaysiinta ee rinjiga ee taangiga electrophoresis si loo ilaaliyo, marka marka conductivity waa sare. , waxa kale oo laga saari karaa xal ultrafiltration si loo hagaajiyo.
Noocyada kala duwan ee dahaarka electrophoresis ee cathodic sidoo kale waxay leeyihiin kala duwanaanta ugu fiican ee xakamaynta ee conductivity ee dareeraha qubeyska, oo ku salaysan conductivity ee isbeddellada yar yar, sida ± 100us / cm ma saameyn doonto waxqabadka filimka daahan, sidaas kala duwan kantaroolka guud waa. ballaaran, ± 30us/cm. conductivity dareeraha qubeyska waa mid aad u sarreeya ama aad u hooseeya dhumucda filimka daahan, muuqaalka iyo dhexgalka filimka ayaa saameyn ku leh, iyada oo dareeraha dareeraha qubayska uu kordho, dhexgalka filimka ayaa sidoo kale ka sarreeya, dhumucda filimka sidoo kale waa ka dhumuc weyn yahay. Dhumucda filimku wuxuu noqon doonaa mid ka sii dhumuc weyn. Dareeraha dareeraha taangiga ayaa ka sarreeya xadka sare ee qiimaha la cayimay ama sare, waxaa loo isticmaali karaa in lagu beddelo xalka ultrafiltration biyaha deionized si loo yareeyo, tusaale ahaan, 300t ee dareeraha taangiga leh biyo deionized halkii 20t ee xalka ultrafiltration, socodka dareeraha taangiga ayaa noqon kara lagu dhimay ± 100us/cm
