Mmetụta nke conductivity na mkpuchi electrophoretic
Conductivity bụ nnọọ mkpa usoro oke na cathodic electrophoresis mkpuchi usoro. Ọ nwere mmekọrịta chiri anya na ike ịtụba, ha na-enwekwa mmetụta dị ukwuu na ihe ndị electrophoretic, nkwụsi ike nke mmiri mmiri bat na mmetụta mkpuchi. N'ikwu okwu n'ozuzu, na elu conductivity nke electrophoresis paint bat, nke elu penetration nke agba ga-abụ; n'ụzọ megidere nke ahụ, ọ bụ ihe dị iche. Ya mere, a ghaghị ịchịkwa conductivity nke mmiri mmiri tank n'ime usoro nhazi usoro. Ya mere, na nnukwu mmepụta usoro nke mkpuchi electrophoretic, conductivity nke electrophoretic mkpuchi nke mmetụta?
Conductivity na-ezo aka ọnụ ọgụgụ nke conductivity na 1cm spacing nke l square centimeters nke okporo osisi elu, na electrophoretic mkpuchi oge na tank, UF mmiri mmiri, osisi mmiri mmiri na ogo nke conductivity eji na mmiri dị ọcha iji gosipụta ogo nke ihe isi ike na. na conductivity, ma ọ bara uru karịa ọkụ eletrik na-egosipụta. Conductivity bụ ngbanwe nke kpọmkwem nguzogide.
Nguzogide dị iche iche (Ω - cm) = 6 ugboro 10 / conductivity, a na-atụkwa ụkpụrụ na μS / cm ma ọ bụ uΩ- cm-1.
The conductivity nke electrophoretic agba tank mmiri mmiri metụtara solids nke tank mmiri mmiri, pH uru na ọdịnaya nke adịghị ọcha ion, wdg Ọ bụ otu n'ime ihe ndị dị mkpa usoro parameters na kwesịrị ịchịkwa n'ime a ụfọdụ nso, size nke nso dabere. na ụdị electrophoretic dị iche iche, na obere ma ọ bụ elu conductivity nke tank mmiri adịghị mma, nke ga-emetụta kpọmkwem àgwà nke eserese electrophoretic.
Mmetụta nke conductivity na mkpuchi electrophoretic:
1. Ruo n'ókè ụfọdụ, conductivity nwere ike ikpebi ọnụọgụ agba nke nwere ike itinye na workpiece site na igwu mmiri ruo n'ókè ụfọdụ.
2. Obere conductivity ga-adịtụ belata ego nke cathodic electrophoresis agba na-edebe, n'ụzọ megidere nke ahụ, elu conductivity ga-ubé dịkwuo ego nke cathodic electrophoresis agba edebe.
3. tank mmiri conductivity dị oke elu ma ọ bụ dị ala, kamakwa na ọkpụrụkpụ nke electrophoresis agba film, ọdịdị, igwu penetration, wdg, karịsịa na tank mmiri conductivity na-abawanye, igwu penetration na-abawanye, mgbe ahụ, ọ bụkwa dịtụ. thicker film ọkpụrụkpụ.
4. Abnormally elu conductivity nke slurry na-emekarị site na elu adịghị ọcha ọdịnaya ma ọ bụ ala pH, na-esonyere ndiiche mgbanwe àgwà nke mkpuchi ihe nkiri, dị ka oroma bee, pinholes, ma ọ bụ laghachi mgbasa nke a dị njọ . ..... na ihe ndị ọzọ na-adịghị mma. Ekwesịrị ijikwa ya site na ultrafilter na sistemụ anode.
Okwu mmeghe dị n'elu bụ conductivity na cathodic electrophoresis agba ụfọdụ mmetụta. N'ikwu okwu n'ozuzu, ekwesịrị ịchịkwa conductivity n'ime oke nke 1200 ± 300μs / cm, n'ihi na conductivity na-adabere n'ịdị mma nke mmiri mmiri tupu electrophoresis na mmeghari nke agba na electrophoresis tank ka a nọgide na-enwe, ya mere, mgbe conductivity dị elu. , enwere ike ịwepụ ihe ngwọta ultrafiltration ka emezie ya.
Ụdị mkpuchi electrophoresis dị iche iche nke cathodic electrophoresis nwekwara njikwa njikwa kacha mma nke conductivity nke mmiri mmiri ịsa ahụ, dabere na ngbanwe nke obere mgbanwe, dị ka ± 100us / cm agaghị emetụta arụmọrụ nke ihe nkiri mkpuchi, ya mere njikwa njikwa n'ozuzu bụ. obosara, ± 30us/cm. conductivity nke mmiri mmiri bat dị oke elu ma ọ bụ dị ala na ọkpụrụkpụ nke ihe nkiri mkpuchi ahụ, ọdịdị na ntinye nke ihe nkiri ahụ nwere mmetụta, ya na mmiri mmiri mmiri na-abawanye, ntinye nke ihe nkiri ahụ dịkwa elu, ọkpụrụkpụ nke ihe nkiri ahụ. dịkwa oke ibu. Ọkpụrụkpụ nke ihe nkiri ahụ ga-adị ntakịrị. Conductivity nke tank mmiri karịrị oke elu nke uru akọwapụtara ma ọ bụ dị elu, enwere ike iji dochie ihe ngwọta ultrafiltration mmiri deionized iji belata, dịka ọmụmaatụ, 300t nke mmiri mmiri na mmiri deionized kama 20t nke ngwọta ultrafiltration, tank mmiri conductivity nwere ike ịbụ. belata site na ± 100us/cm.
