Nā ʻAno Lining o nā Mīkini Kahe Electromagnetic

Hoʻolauna

Nā mika kahe uilahe mea nuinā mea kanino ke ana ʻana i ke kahe o nā wai conductive i nā noi ʻoihana he nui. ʻO ka uhi o kahi mika kahe electromagnetic e lawelawe i nā hana koʻikoʻi he nui. Hana ia ma ke ʻano he pale ma waena o nā electrodes a me ka wai, e pale ana i nā electrodes mai ka pala a me ka hōʻoia ʻana i ke ana pololei. Eia kekahi, pale ia i ka paia o loko o ke kino mika kahe mai nā hopena erosive a corrosive paha o ka wai. Hoʻolālā ʻia nā ʻano uhi like ʻole e hoʻokō i nā koi like ʻole o nā wai like ʻole a me nā kūlana hana.

Nā Mea Lining Maʻamau

1. Nā uhi laholio

 

• Lahopa kūlohelohe
  • He koho uhi kūpono ke ʻano o ka laholio kūlohelohe. Loaʻa iā ia ka maʻalahi maikaʻi, e hiki ai iā ia ke kū i kekahi mau pilikia mechanical i ka wā o ke kau ʻana a me ka hana. He kūpono ia no ke ana ʻana i nā wai me nā mahana haʻahaʻa, maʻamau a hiki i ka 60 - 80°C. Kūpaʻa hoʻi ka laholio kūlohelohe i nā hopena wai maʻamau he nui, e lilo ia i koho kaulana no nā noi ma nā ʻoihana mālama wai a me ka wai hoʻoneoneo. No ka laʻana, ma kahi hale hana mālama wai hoʻoneoneo kūlanakauhale, hiki ke hoʻohana ʻia nā mika kahe electromagnetic i hoʻopaʻa ʻia me ka laholio kūlohelohe e ana i ke kahe o ka wai hoʻoneoneo maka, kahi e loaʻa ai i ka wai kekahi mau mea paʻa i hoʻokuʻu ʻia a me nā ʻano kemika like ʻole ma nā mahana kūpono.
• ʻO ka laholio Neoprene
  • Hāʻawi ka ʻōpala Neoprene i ke kūpaʻa kemika i hoʻonui ʻia i hoʻohālikelike ʻia me ka ʻōpala maoli. Hiki iā ia ke kūʻē i ka hana o nā aila, nā wahie, a me nā kemika he nui. Hoʻohana pinepine ʻia nā mika kahe electromagnetic i hoʻopaʻa ʻia me Neoprene i nā noi ʻoihana kahi e hiki ai i ka wai ke hoʻopili me ia mau mea. No ka laʻana, i ka ʻoihana hana kaʻa, i ke ana ʻana i ke kahe o nā wai coolant e loaʻa paha nā mea anti-freeze a me nā mea hoʻohui ʻē aʻe, hāʻawi ka lining neoprene i ka palekana hilinaʻi. ʻOi aku ka kiʻekiʻe o ka pae mahana no nā mika i hoʻopaʻa ʻia me neoprene ma mua o ka ʻōpala maoli, a hiki i kahi o 80 - 100°C.
• ʻO ka laholio Butyl
  • He kūpono loa ka pale ʻana o ka butyl rubber i nā kinoea a me ka mahu wai. He kūpaʻa loa ia i ka hoʻouka kaua kemika, ʻoi aku hoʻi mai nā waikawa a me nā alkalis. ʻO kēia ka mea e kūpono ai no nā noi kahi e ʻino loa ai ka wai. I ka ʻoihana kemika, i ke ana ʻana i ke kahe o nā hopena waikawa ikaika a alkali paha, ʻo nā mika kahe electromagnetic i hoʻopaʻa ʻia me ka butyl rubber kahi koho makemake ʻia. Hiki iā lākou ke hana ma nā mahana mai - 40°C a i 120°C, e hāʻawi ana i kahi puka makani mahana hana ākea no nā kaʻina hana ʻoihana like ʻole.

2. Nā uhi plastik

 

• Polyvinyl Chloride (PVC)
  • He mea uhi plastik i hoʻohana nui ʻia ka PVC. He ʻano pipiʻi ke kumukūʻai a hāʻawi i ke kūpaʻa kemika maikaʻi i nā kemika maʻamau he nui. He kūpono nā mika kahe electromagnetic i hoʻopaʻa ʻia me ka PVC no nā noi ma ka ʻoihana meaʻai a me ka mea inu, ʻoiai ʻaʻohe ʻawahia ka PVC a kūlike me nā kūlana hoʻomaʻemaʻe kūpono. No ka laʻana, ma kahi hale hana hana wai huaʻai, hiki ke hoʻohana ʻia nā mika kahe i hoʻopaʻa ʻia me ka PVC e ana i ke kahe o ka wai i ka wā o ke kaʻina hana. Eia nō naʻe, he palena iki ka laulā mahana o ka PVC, maʻamau a hiki i ka 60 - 70°C.
• Polyethylene (PE)
  • ʻO PE, ʻoiai ka polyethylene density kiʻekiʻe (HDPE), ua kaulana ʻia no kona paʻakikī a me ke kūpaʻa kemika. Hoʻohana pinepine ʻia nā mika kahe electromagnetic i hoʻopaʻa ʻia e HDPE i nā noi kahi e loaʻa ai i ka wai nā ʻāpana abrasive. I ka ʻoihana mining, i ke ana ʻana i ke kahe o ka slurry (kahi hui ʻana o ka wai a me nā ʻāpana paʻa), hiki i ka lining HDPE ke kū i ka abrasion i hoʻokumu ʻia e nā ʻāpana paʻa. Hiki i nā mika i hoʻopaʻa ʻia e PE ke hana i nā mahana a hiki i kahi o 80 - 90°C, ma muli o ke ʻano kikoʻī o ka polyethylene.
• Polytetrafluoroethylene (PTFE)
  • He palakika hana kiʻekiʻe ka PTFE me ke kūpaʻa kemika koʻikoʻi. Hiki iā ia ke kū'ē i nā kemika āpau, me nā waikawa ikaika, nā alkalis, a me nā mea hoʻoheheʻe organik. Hoʻohana ʻia nā mika kahe electromagnetic i hoʻopaʻa ʻia me ka PTFE i nā wahi ʻino loa, e like me ka ʻoihana lāʻau lapaʻau i ke ana ʻana i nā hopena kemika reactive kiʻekiʻe. Loaʻa iā PTFE kahi coefficient haʻahaʻa loa o ka friction, e kōkua ana i ka hōʻemi ʻana i ka hoʻopili ʻana o ka wai i ka lining, e hōʻoiaʻiʻo ana i ke ana pololei ʻana o ke kahe. He ākea loa ka pae mahana no nā mika i hoʻopaʻa ʻia me ka PTFE, mai - 200°C a i 260°C, e kūpono ana no nā ʻano noi like ʻole o ka mahana.

3. Nā uhi keramika

 

• Nā Keramika Alumina
  • He paʻakikī loa nā keramika alumina a kūpaʻa i ka ʻaʻahu. He kūpono lākou no nā noi kahi i loaʻa ai i ka wai nā ʻāpana abrasive kiʻekiʻe. I ka ʻoihana sima, no ka laʻana, i ke ana ʻana i ke kahe o ka slurry sima, nona nā ʻāpana sima abrasive, hiki i nā mika kahe electromagnetic i hoʻopaʻa ʻia i ka keramika alumina ke hāʻawi i ka lawelawe hilinaʻi lōʻihi. Loaʻa i nā keramika alumina ke kūpaʻa kemika maikaʻi, ʻoi aku hoʻi i nā waikawa a me nā alkalis i nā mahana kiʻekiʻe. Hiki iā lākou ke kū i nā mahana a hiki i kahi o 1000°C, e kūpono ai no nā kaʻina hana ʻoihana wela kiʻekiʻe.
• Nā keramika Zirconia
  • Hāʻawi nā keramika Zirconia i nā waiwai mechanical maikaʻi loa a me ke kūpaʻa kemika. ʻOi aku ko lākou kūpaʻa i ka haʻalulu wela i hoʻohālikelike ʻia me kekahi mau mea keramika ʻē aʻe. Hoʻohana ʻia nā mika kahe electromagnetic i hoʻopaʻa ʻia me Zirconia i nā noi kahi e loli wikiwiki ai ka mahana o ka wai. I ka ʻoihana hana aniani, i ke ana ʻana i ke kahe o nā wai e pili ana i ke aniani heheʻe, hiki i ka lining keramika zirconia ke lawelawe i ke kaiapuni kiʻekiʻe a me ka hoʻouka kaua kemika, a me ke kaumaha wela i ka wā o ke kaʻina hana.

Nā Manaʻo Koho

I ke koho ʻana i ke ʻano o ka uhi no ka lumipakumika kahe electromagnetic, pono e noʻonoʻo ʻia kekahi mau mea. He mea koʻikoʻi ke ʻano o ke kahe, me kona ʻano kemika, ka mahana, ke kaomi, a me ke alo o nā ʻāpana abrasive. No nā wai ʻino loa, pono paha nā mea e like me PTFE a i ʻole kekahi mau keramika. I nā noi me nā wai abrasive, makemake ʻia nā uhi pale ʻaʻahu e like me ka rubber (no nā hihia abrasive liʻiliʻi) a i ʻole nā ​​​​ceramic. Pono hoʻi nā palena o ka mahana a me ke kaomi o ka mea uhi e kūlike me nā kūlana hana o ka mika kahe. Eia kekahi, pono e noʻonoʻo ʻia ke kumukūʻai a me ka kūlike me ka ʻōnaehana holoʻokoʻa, me nā electrodes a me ke kino mika.

I ka hopena, ʻo ke koho ʻana i ke ʻano kūpono o ka uhi uhi no ka lolemika kahe electromagnetiche hoʻoholo koʻikoʻi ia e pili pono ana i ka hana, ke kūpaʻa, a me ka pololei o ke ana ʻana o ke kahe ʻana i nā noi ʻoihana like ʻole. Ma ka noʻonoʻo pono ʻana i nā ʻano o ke kahe a me nā kūlana hana, hiki ke koho ʻia ka mea uhi kūpono loa e hōʻoia i ka hana hilinaʻi a me ka pono o ka mika kahe electromagnetic.
