Kaʻina electrophoresis

ʻO ke kaʻina hana maʻamau o ka anodic electrophoresis ʻo ia: ka mea hana ma mua o ka mālama ʻana (ka wehe ʻana i ka aila → ka holoi wai wela → ka holoi ʻana i ka wai anuanu → ka holoi ʻana i ka wai wela phosphating → passivation) → anode electrophoresis → ka mea hana ma hope o ka mālama ʻana (holoi wai maʻemaʻe → hoʻomaloʻo. )

1. Wehe i ka aila.ʻO ka hoʻonā maʻamau he hopena hoʻoheheʻe kemika alkaline wela me kahi mahana o 60°C (hoʻomaʻamaʻa mahu) a me kahi manawa o 20 mau minuke.

2. Holoi i ka wai wela.Ka wela 60 ℃ (hoʻomaʻamaʻa mahu), manawa 2min.

3. Wehe ʻana.E hoʻohana i ka H2SO4 a i ʻole HCI, e like me ka hydrochloric acid rust removal solution, HCI huina acidity ≥ 43 helu;kaʻakika manuahi > 41 helu;hoʻohui i ka 1.5% mea hoʻomaʻemaʻe;holoi ma ka lumi wela no 10 a 20 mau minuke.

4. Holoi i ka wai anuanu.Holoi i ka wai anuanu no 1 minuke.

5. Phosphating.E hoʻohana i ka phosphating wela waena (phosphating no 10 mau minuke ma 60°C), a hiki ke kūʻai ʻia ka hopena phosphating i nā huahana i hoʻopau ʻia.

Hiki ke hoʻololi ʻia ke kaʻina hana ma luna e ka sandblasting →> holoi wai

6. Ka hoʻopaʻapaʻa.E hoʻohana i nā kinikona e pili ana i ka solution phosphating (i hāʻawi ʻia e ka mea hana e kūʻai aku ana i ka solution phosphating) a waiho i ka lumi wela no 1 a 2 mau minuke.

7. Anodic electrophoresis.ʻO ka haku mele electrolyte: H08-1 ʻeleʻele electrophoretic pena, paʻa maʻiʻo ʻāpana hapa 9% ~ 12%, ka wai distilled hakina 88% ~ 91%.Voltage: (70 + 10)V;manawa: 2 ~ 2.5min;pena wai wela: 15 ~ 35 ℃;pena wai PH waiwai: 8~8.5.E hoʻomaopopo pono e pio ka mea hana ke komo a puka i waho o ka slot.I ka wā o ke kaʻina hana electrophoresis, e emi mālie ke au i ka wā e mānoanoa ai ke kiʻi pena.

8. E holoi me ka wai maʻemaʻe.Holoi i ka wai anuanu.

9. Ka maloo ana.E puhi i ka umu ma (165+5) ℃ no 40-60 mau minuke.
