wiliwili uila 2% cerium WC20 cerium tungsten electrode
Hoʻohui ʻia ʻo Tungsten me 2% ceria e hana i kahi tungsten-cerium oxide composite i hoʻohana pinepine ʻia ma ke ʻano he ʻano radioactive ʻole i nā electrodes tungsten thoriated i nā noi welding.
Hiki ke ʻokoʻa ka waihoʻoluʻu o ka tungsten i loaʻa ka 2% ceria akā ʻo ka maʻamau he hina hina a keʻokeʻo paha. Hiki ke hilinaʻi ʻia ka malu kikoʻī i nā mea e like me ke kaʻina hana a me nā uhi ʻē aʻe a i ʻole nā lāʻau lapaʻau i pili i ka mea.
ʻO ka tungsten Thoriated a me ka cerium tungsten he mau electrodes tungsten no ka hoʻopili ʻana, akā loaʻa iā lākou nā ʻano like ʻole a me nā waiwai.
1.Thoriated tungsten:
-Thoriated tungsten electrodes loaʻa kahi liʻiliʻi o ka thorium oxide (maʻamau ma kahi o 1-2%). ʻO ka hoʻohui ʻana o ka thorium e hoʻomaikaʻi i nā hiʻohiʻona electron emission o ka electrode, e maʻalahi ai ka hoʻomaka a mālama ʻana i ke arc welding.
ʻIke ʻia ʻo Thoriated tungsten no kona hiki ke lawe i kēia manawa, ka paʻa arc maikaʻi a me ke ola lōʻihi. Hoʻohana maʻamau ia i nā noi wiliwī DC, ʻoi loa no nā mea wili e like me ke kila kalapona, ke kila kila, nā nickel alloys a me ka titanium.
2. Tungsten cerium:
- Loaʻa nā electrodes Cerium tungsten i ka cerium oxide ma ke ʻano he mea hoʻohui. Loaʻa nā haku mele cerium tungsten maʻamau i ka 1.5-2% cerium oxide.
- Loaʻa i ka Cerium tungsten ka hoʻomaka ʻana a me ka paʻa, ʻoi aku hoʻi i nā noi wili o kēia manawa. He kūpono ia no ka hoʻoheheʻe AC a me DC a no laila kūpono i nā ʻano mea like ʻole a me nā kaʻina hana kuʻi.
- Ua koho pinepine ʻia ʻo Cerium tungsten ma ke ʻano he ʻano radioactive ʻole i ka thorium tungsten e hoʻoponopono i nā hopohopo e pili ana i nā pilikia olakino e pili ana i ka hoʻolaha ʻana i ka thorium.
I ka hōʻuluʻulu ʻana, ʻoiai ua hoʻohana ʻia nā electrodes tungsten thoriated a me nā electrodes cerium tungsten i ka welding, loaʻa iā lākou nā haku like ʻole a kūpono i nā noi a me nā kūlana wili like ʻole. Ua ʻike ʻia ʻo Thoriated tungsten no kona hiki ke halihali i kēia manawa a hoʻohana pinepine ʻia i ka welding DC, aʻo ka cerium tungsten he arc maikaʻi ka hoʻomaka ʻana a me ke kūpaʻa a kūpono ia no ka hoʻoheheʻe AC a me DC.
ʻAe, ʻo 2% thoriated tungsten electrodes i manaʻo ʻia he radioactive liʻiliʻi ma muli o ka loaʻa ʻana o ka thorium oxide i ka haku mele. ʻO Thorium kahi mea radioactive kūlohelohe i loaʻa i nā electrodes tungsten e hoʻokuʻu ana i nā ʻāpana alpha haʻahaʻa. ʻOiai he haʻahaʻa haʻahaʻa nā pae radioactivity, he mea nui ia e mālama pono a hoʻolei aku i nā electrodes tungsten thoriated e hōʻemi i ka ʻike.
Ma muli o ke ʻano radioactive o ka thorium, ʻo ka hoʻohana ʻana, ka mālama ʻana a me ka hoʻokuʻu ʻana i nā electrodes thorium tungsten e pono ai ka palekana a me ka noʻonoʻo hoʻoponopono. ʻO ka hopena, aia kahi hoʻololi i nā koho non-radioactive e like me ka tungsten cerium, tungsten lanthanate a i ʻole nā mea ʻē aʻe o ka honua ʻē aʻe doped tungsten electrodes, ʻoi aku hoʻi i nā ʻoihana kahi mea koʻikoʻi ka palekana o ka limahana a me nā pilikia kaiapuni.
