Oxygen (O2)

Nā palena ʻenehana

Oxygenhe kinoea kala ʻole a ʻala ʻole. ʻO ia ke ʻano mea maʻamau o ka oxygen. E pili ana i ka ʻenehana, lawe ʻia ka oxygen mai ke kaʻina liquefaction o ka ea, a ʻo ka oxygen i ka lewa e pili ana i 21%. He kinoea kala ʻole a ʻala ʻole ka Oxygen me ke ʻano kemika O2, ʻo ia ke ʻano mea maʻamau o ka oxygen. ʻO ka helu hoʻoheheʻe -218.4°C, a ʻo ka helu hoʻolapalapa -183°C. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai. Ma kahi o 30mL o ka oxygen i hoʻoheheʻe ʻia i ka 1L o ka wai, a ʻo ka wai oxygen he uliuli. ʻOi aku ka ikaika o nā waiwai kemika o ka oxygen. Ma waho aʻe o nā kinoea a me nā mea metala me ka haʻahaʻa haʻahaʻa e like me ke gula, platinum, a me ke kālā, hiki i ka hapa nui o nā mea ke hana me ka oxygen. Ua kapa ʻia kēia mau ʻano hoʻoheheʻe ʻana. ʻO nā hopena Redox e pili ana i nā hopena i hoʻololi ʻia a hoʻololi ʻia paha nā electrons. Loaʻa i ka Oxygen nā waiwai kākoʻo a me ka hoʻoheheʻe ʻana. He koʻikoʻi ko ka oxygen lāʻau lapaʻau i ka mālama ʻana i ka haukapila a me ka mālama lapaʻau, e like me ka resuscitation, ka ʻokiʻoki, a me nā ʻano lapaʻau like ʻole. Hiki ke hoʻohana ʻia ka oxygen e like me ke kinoea hanu no ka luʻu ʻana ma hope o ka hui ʻana me ka nitrogen a i ʻole helium. Hiki ke loaʻa ka oxygen pāʻoihana ma ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana i ka ea i loko o ke kaiapuni i kahi mea kanu hoʻokaʻawale ea. . ʻO ka hoʻohana ʻoihana nui o ka oxygen ʻo ka hoʻopau ʻana. Hiki i nā mea he nui i hiki ʻole ke puhi ʻia i ka ea ke puhi i ka oxygen, no laila ʻo ka hui ʻana i ka oxygen me ka ea e hoʻomaikaʻi nui ai i ka pono o ka puhi ʻana i nā mea kila, nā metala non-ferrous, aniani a me nā ʻoihana. Ma hope o ka hui ʻana me ke kinoea wahie, hoʻohana nui ʻia i ka ʻoki ʻana, ke kuʻi ʻana, ka brazing a me ka puhi aniani e hāʻawi i kahi kiʻekiʻe o ka wela ma mua o ka puhi ʻana o ka ea, a laila e hoʻomaikaʻi ai i ka pono. E mālama i ka mālama ʻana: E kūʻai i loko o kahi hale kūʻai ʻoluʻolu. E mālama i ke ahi a me nā kumu wela. ʻAʻole pono ka mahana o ka mālama ʻana ma mua o 30 ° C. Pono e mālama ʻokoʻa ʻia mai nā mea hiki ke puhi ʻia, nā pauka metala ikaika, a me nā mea ʻē aʻe, a pale i ka waiho ʻana. Pono e hoʻolako ʻia ka wahi e mālama ai me nā lako lapaʻau ulia pōpilikia.

Noi:

①Hoʻohana ʻoihana:

ʻO ka hana kila, hoʻoheheʻe metala ʻole.

②Hoʻohana Lapaʻau:

I ka mālama ʻana i nā pilikia e like me ka ʻūhā a me ka hōʻeha puʻuwai, i ka mālama ʻana i nā maʻi me nā maʻi hanu a me ka anesthesia.

③Ka hana semiconductor:

ʻO ka waiho ʻana o ka mahu kemika o ka silicon dioxide, ka ulu ʻana o ka thermal oxide, ka etching plasma, ka wehe ʻana o ka plasma photoresist a me ke kinoea lawe i kekahi mau hana deposition/diffusion.

Pūʻolo maʻamau:

Pōmaikaʻi:

①Ma mua o ʻumi makahiki ma ka mākeke;

②Ka mea hana palapala ISO;

③Hoʻouna wikiwiki;

④Stable kumu kumu waiwai;

⑤ ʻO ka ʻōnaehana hoʻopaʻa inoa pūnaewele no ka hoʻokele maikaʻi ʻana i kēlā me kēia pae;

⑥Ke koi kiʻekiʻe a me ke kaʻina hana no ka mālama ʻana i ka cylinder ma mua o ka hoʻopiha ʻana;
