Ka hopena o ka conductivity i ka uhi electrophoretic

He mea koʻikoʻi koʻikoʻi ka conductivity i ke kaʻina hana hoʻopili cathodic electrophoresis. He pili pili loa ia me ka mana hoolei, a he mana nui ko lakou i na waiwai electrophoretic, ka paa o ka wai auau a me ka hopena o ka uhi. ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka conductivity o ka ʻauʻau pena electrophoresis, ʻoi aku ka kiʻekiʻe o ke komo ʻana o ka pena; aka, he ku e. No laila, pono e hoʻomalu pono ʻia ka conductivity o ka wai pahu i loko o ka laulā o nā hoʻoponopono kaʻina. No laila, i loko o ke kaʻina hana nui o ka electrophoretic uhi, ka conductivity o ka electrophoretic uhi o ka mana?

ʻO ka conductivity e pili ana i ka nui o ka conductivity i ka 1cm spacing o l square centimeters o ka pole surface, i nā hanana electrophoretic coating i loko o ka pahu, UF wai, pole wai a me ke degere o ka conductivity i hoʻohana ʻia i ka wai maʻemaʻe e hōʻike i ke kiʻekiʻe o ka paʻakikī me ka conductivity, akā maikaʻi hoʻi ma mua o ke kūpaʻa uila e hōʻike. ʻO ka Conductivity ka pānaʻi o ke kū'ē kūikawā.

Kū'ē kiko'ī (Ω - cm) = 6 manawa 10/conductivity, a ua ana ka conductivity ma μS/cm a i ʻole uΩ- cm-1.

ʻO ka conductivity o ka electrophoretic paint tank wai pili i nā mea paʻa o ka pahu wai, ka waiwai pH a me ka ʻike o nā ion impurity, a me nā mea ʻē aʻe. ma nā ʻano o nā pena electrophoretic, a ʻaʻole maikaʻi ka conductivity haʻahaʻa a kiʻekiʻe paha o ka wai pahu, e hoʻopili pololei i ka maikaʻi o ka pena electrophoretic.

Ka hopena o ka conductivity i ka uhi electrophoretic:

1. I kekahi nui, hiki i ka conductivity ke hoʻoholo i ka nui o ka pena i hiki ke hoʻopili ʻia i ka mea hana ma ka ʻauʻau ʻana i kekahi ʻano.

2. ʻO ka emi iki o ka conductivity e hoʻemi iki i ka nui o ka pena cathodic electrophoresis i waiho ʻia, ma ke ʻano, e hoʻonui iki ka conductivity kiʻekiʻe i ka nui o ka pena cathodic electrophoresis i waiho ʻia.

3. He kiʻekiʻe a haʻahaʻa paha ka conductivity tank wai, akā ma ka mānoanoa o ke kiʻi pena electrophoresis, ke ʻano, ke komo ʻana i ka ʻauʻau, a me nā mea ʻē aʻe, ʻoi aku ka nui me ka piʻi ʻana o ka conductivity wai, ua hoʻonui ʻia ka ʻauʻau ʻana, a laila ua pili pū kekahi. mānoanoa kiʻiʻoniʻoni mānoanoa.

4. Abnormally kiʻekiʻe conductivity o ka slurry mea pinepine i ka haumia maʻiʻo a haʻahaʻa pH, a ua hele pū me ka abnormal loli i ka maikaʻi o ka uhi kiʻiʻoniʻoni, e like me ka alani peel, pinholes, a hoʻi i ka dissolution o koʻikoʻi . ..... a me nā mea ʻino ʻē aʻe. Pono e mālama ʻia e ka ultrafilter me ka ʻōnaehana anode.

ʻO ka hoʻolauna ma luna nei ka conductivity ma ka cathodic electrophoresis pena i kekahi o nā hopena. ʻO ka mea maʻamau, pono e mālama ʻia ka conductivity i loko o ka laulā o 1200 ± 300μs / cm, no ka mea, ke hilinaʻi nui nei ka conductivity i ka maikaʻi o ka wai deionized ma mua o ka electrophoresis a me ka hana hou o ka pena i loko o ka pahu electrophoresis e mālama ʻia, no laila ke kiʻekiʻe ka conductivity. , hiki ke hoʻokuʻu ʻia ka hopena ultrafiltration e hoʻoponopono ʻia.

Loaʻa i nā ʻano like ʻole o ka cathodic electrophoresis coatings ka mana maikaʻi loa o ka conductivity o ka wai ʻauʻau, e pili ana i ka conductivity o nā hoʻololi liʻiliʻi, e like me ± 100us/cm ʻaʻole e hoʻopilikia i ka hana o ke kiʻi uhi, no laila ke ʻano o ka mana ākea. akea, ± 30us/cm. ʻOi aku ka kiʻekiʻe a i ʻole ka haʻahaʻa haʻahaʻa o ka ʻauʻau wai ma ka mānoanoa o ke kiʻi ʻoniʻoni, ʻo ka hiʻohiʻona a me ke komo ʻana o ka kiʻiʻoniʻoni he hopena, me ka piʻi ʻana o ka conductivity wai ʻauʻau, ʻoi aku ka kiʻekiʻe o ke komo ʻana o ka kiʻiʻoniʻoni, ʻoi aku ka mānoanoa o ke kiʻi. ʻoi aku ka mānoanoa. E ʻoi aku ka mānoanoa o ke kiʻiʻoniʻoni. ʻOi aku ka nui o ka conductivity wai i ka palena kiʻekiʻe o ka waiwai i ʻōlelo ʻia a kiʻekiʻe paha, hiki ke hoʻohana ʻia e hoʻololi i ka wai deionized ultrafiltration solution e hōʻemi, no ka laʻana, 300t o ka wai pahu me ka wai deionized ma kahi o 20t o ka hopena ultrafiltration, hiki ke hoʻololi i ka conductivity wai pahu. hoemiia e ± 100us/cm.
