Tasirin rashin daidaituwa a cikin shafi na electrophoretic

Conductivity ne mai matukar muhimmanci tsari siga a cathodic electrophoresis shafi tsari. Yana da kusanci sosai tare da ikon jefawa, kuma suna da tasiri mai yawa akan abubuwan electrophoretic, kwanciyar hankali na ruwan wanka da tasirin shafi. Gabaɗaya magana, mafi girman ɗab'i na wankan fenti na electrophoresis, mafi girman shigar fenti zai kasance; akasin haka, akasin haka. Sabili da haka, ya kamata a kula da ƙayyadaddun motsi na ruwa na tanki a cikin kewayon ƙa'idodin tsari. Don haka a cikin babban tsari na samar da kayan aiki na electrophoretic, ƙaddamarwa na murfin electrophoretic na tasiri?

Conductivity yana nufin adadin conductivity a cikin 1cm tazara na l murabba'in santimita na iyakacin duniya surface, a cikin electrophoretic shafi lokuta a cikin tanki, UF ruwa, iyakacin duniya ruwa da kuma mataki na conductivity amfani a cikin tsarkakẽwar ruwa don bayyana mataki na wahala tare da conductivity, amma kuma amfani fiye da lantarki juriya don bayyana. Conductivity shine ma'anar juriya ta musamman.

Ƙimar ƙayyadaddun juriya (Ω - cm) = 6 sau 10 / conductivity, kuma ana auna ƙarfin aiki a cikin μS/cm ko uΩ- cm-1.

A conductivity na electrophoretic Paint tank ruwa yana da alaka da daskararru na tanki ruwa, pH darajar da abun ciki na najasa ions, da dai sauransu Yana daya daga cikin muhimman matakai sigogi da ya kamata a sarrafa a cikin wani kewayon, girman da kewayon dogara da irin electrophoretic Paint, da kuma low ko high conductivity na tanki ruwa ba shi da kyau, wanda kai tsaye zai shafi ingancin electrophoretic zanen.

Tasirin conductivity a cikin shafi na electrophoretic:

1. Har zuwa wani matsayi, ƙaddamarwa na iya ƙayyade adadin fenti da za a iya amfani da shi zuwa aikin aikin ta yin iyo zuwa wani matsayi.

2. Ƙarƙashin ƙaddamarwa zai ɗan rage yawan adadin fenti na electrophoresis na cathodic da aka ajiye, akasin haka, haɓakaccen haɓakawa zai ɗan ƙara yawan adadin fenti na electrophoresis na cathodic da aka ajiye.

3. Tank ruwa conductivity ne ma high ko ma low, amma kuma a kan kauri daga cikin electrophoresis Paint film, bayyanar, iyo shigar azzakari cikin farji, da dai sauransu, musamman tare da tanki ruwa watsin ƙãra, iyo shigar azzakari cikin farji kuma ya karu, sa'an nan shi ne kuma in mun gwada da thicker film kauri.

4. Abnormally high conductivity na slurry ne sau da yawa lalacewa ta hanyar high najasa abun ciki ko low pH, kuma yana tare da m canje-canje a cikin ingancin da shafi fim, kamar orange kwasfa, pinholes, ko komawa zuwa rushe wani tsanani ...... da sauran m mamaki. Yana buƙatar sarrafa ta ultrafilter tare da tsarin anode.

Gabatarwar da ke sama ita ce ƙaddamarwa akan electrophoresis na cathodic fenti wasu tasirin. Gabaɗaya magana, yakamata a sarrafa ƙarfin aiki a cikin kewayon 1200 ± 300μs / cm, saboda haɓakar ya dogara da ingancin ruwan da aka lalata kafin electrophoresis da sabuntawar fenti a cikin tanki na electrophoresis don kiyayewa, don haka lokacin da ƙarfin lantarki ya yi girma, Hakanan ana iya fitar da maganin ultrafiltration don daidaitawa.

Daban-daban na cathodic electrophoresis coatings kuma suna da mafi kyau iko kewayon conductivity na wanka ruwa, dangane da conductivity na kananan canje-canje, kamar ± 100us / cm ba zai shafi yi na shafi fim, don haka general iko kewayon ne fadi, ± 30us / cm. Bath conductivity na ruwa yana da yawa ko kuma ƙasa da kauri na fim ɗin mai rufi, bayyanar da shigar da fim ɗin yana da tasiri, tare da haɓakar ruwa na wanka yana ƙaruwa, shigar da fim ɗin kuma ya fi girma, kauri na fim ɗin kuma ya fi girma. Kauri daga cikin fim zai zama in mun gwada da thicker. Ƙarƙashin ruwa na tanki ya wuce iyakar ƙayyadaddun ƙimar ko babba, ana iya amfani dashi don maye gurbin maganin ultrafiltration na ruwa don rage, alal misali, 300t na ruwa na tanki tare da ruwan da aka lalata maimakon 20t na ultrafiltration bayani, za'a iya rage tasirin ruwa na tanki ta ± 100us / cm.
