I-oksijini (O2)

Amapharamitha obuchwepheshe

I-oxygeniyigesi engenambala nengenaphunga. Yindlela ejwayelekile kakhulu ye-oxygen. Ngokuphathelene nobuchwepheshe, i-oxygen ikhishwa enkambisweni yokuncibilika komoya, kanti i-oxygen emoyeni ibiza cishe u-21%. I-oxygen iyigesi engenambala nengenaphunga enefomula yamakhemikhali i-O2, okuyiyona ndlela ejwayelekile kakhulu ye-oxygen. Indawo yokuncibilika ingu-218.4°C, kanti indawo yokubila ingu-183°C. Ayincibiliki kalula emanzini. Cishe i-30mL ye-oxygen incibilika ku-1L yamanzi, kanti i-oxygen ewuketshezi iluhlaza okwesibhakabhaka. Izakhiwo zamakhemikhali ze-oxygen zisebenza kakhulu. Ngaphandle kwamagesi angavamile nezinto zensimbi ezinomsebenzi ophansi njengegolide, iplatinum, nesiliva, iningi lezinto lingasabela ne-oxygen. Lokhu kusabela kubizwa ngokuthi ukusabela kwe-oxidation. Ukusabela kwe-Redox kubhekisela ekuphenduleni lapho ama-electron edluliselwa khona noma eshintshwa khona. I-oxygen inezakhiwo ezisekela ukushisa kanye ne-oxidation. I-oxygen yezokwelapha idlala indima ebalulekile ekwelashweni esibhedlela kanye nokunakekelwa kwezokwelapha, njengokuvuselela, ukuhlinzwa, kanye nokwelashwa okuhlukahlukene. I-oksijini ingasetshenziswa futhi njengegesi yokuphefumula yokuntywila ngemuva kokuxutshwa ne-nitrogen noma i-helium. I-oksijini yezentengiselwano ingatholakala ngokucwilisa nokucwilisa umoya endaweni ezungezile esitshalweni sokuhlukanisa umoya. . Ukusetshenziswa okuyinhloko kwezimboni kwe-oksijini ukusha. Izinto eziningi ezivame ukungashi emoyeni zingasha emoyeni, ngakho-ke ukuxuba i-oksijini nomoya kuthuthukisa kakhulu ukusebenza kahle kokusha ezimbonini zensimbi, izinsimbi ezingenayo i-ferrous, ingilazi kanye nekhonkrithi. Ngemva kokuthi ixutshwe negesi kaphethiloli, isetshenziswa kabanzi ekusikeni, ekushiseni, ekubhebheni nasekuvutheleni ingilazi ukuze kunikezwe izinga lokushisa eliphakeme kunokushisa komoya, ngaleyo ndlela kuthuthukiswe ukusebenza kahle. Izinyathelo zokugcina: Gcina endaweni yokugcina epholile, enomoya. Gcina kude nomlilo kanye nemithombo yokushisa. Izinga lokushisa lokugcina akufanele lidlule ku-30°C. Kufanele ligcinwe ngokwehlukana nezinto ezivuthayo, impuphu yensimbi esebenzayo, njll., futhi ugweme ukugcina okuxubile. Indawo yokugcina kufanele ifakwe imishini yokwelapha ephuthumayo evuzayo.

Isicelo:

①Ukusetshenziswa Kwemboni:

Ukwenza insimbi, ukuncibilikisa insimbi engenansimbi. Ukusika izinto zensimbi.

②Ukusetshenziswa Kwezokwelapha:

Ekwelapheni izimo eziphuthumayo njengokuphefumula kanye nokuhlaselwa yinhliziyo, ekwelapheni iziguli ezinezinkinga zokuphefumula kanye ne-anesthesia ngosizo lokuqala.

③Ukwenziwa kwe-semiconductor:

Ukufakwa kwe-silicon dioxide ngamakhemikhali, ukukhula kwe-thermal oxide, ukugqwala kwe-plasma, ukukhipha i-photoresist kanye negesi yokuthwala igesi nge-plasma emisebenzini ethile yokufaka/yokusabalalisa.

Iphakheji evamile:

Inzuzo:

①Iminyaka engaphezu kweyishumi emakethe;

②Umkhiqizi wesitifiketi se-ISO;

③Ukulethwa okusheshayo;

④Umthombo wezinto zokusetshenziswa eziqinile;

⑤Uhlelo lokuhlaziya oluku-inthanethi lokulawula ikhwalithi kuzo zonke izinyathelo;

⑥Isidingo esiphezulu kanye nenqubo ecophelelayo yokuphatha isilinda ngaphambi kokugcwalisa;
