I-Oxygen (O2)

Imingcele yezobuchwepheshe

Umoya-mpiloiyigesi engenambala futhi engenaphunga. Kuyindlela ejwayelekile kakhulu ye-oxygen eyisisekelo. Ngokuphathelene nobuchwepheshe, umoya-mpilo ukhishwa enqubweni yokuncibilika komoya, futhi umoya-mpilo osemoyeni uthatha cishe u-21%. Umoya-mpilo igesi elingenambala nelingenaphunga elinefomula yamakhemikhali i-O2, okuwuhlobo oluvame kakhulu lomoya-mpilo. Iphuzu elincibilikayo lingu-218.4°C, kanti indawo yokubila ingu-183°C. Ayincibiliki kalula emanzini. Cishe u-30mL womoya-mpilo uncibilika ku-1L wamanzi, futhi umoya-mpilo owuketshezi uluhlaza okwesibhakabhaka. Amakhemikhali omoya-mpilo asebenza kakhulu. Ngaphandle kwamagesi angavamile nezinto zensimbi ezinomsebenzi ophansi njengegolide, iplatinamu, nesiliva, ama-elementi amaningi angasabela ngomoya-mpilo. Lokhu kusabela kubizwa ngokuthi ukusabela kwe-oxidation. Ukusabela kwe-Redox kubhekisela ekuphenduleni lapho ama-electron adluliselwa noma agudluzwa khona. Umoya-mpilo unezinto ezisekela ukuvutha kanye ne-oxidizing. Umoya-mpilo wezokwelapha udlala indima ebalulekile ekwelapheni kwasesibhedlela nasekunakekelweni komtholampilo, njengokuvuselela, ukuhlinzwa, nokwelashwa okuhlukahlukene. I-oksijeni ingasetshenziswa futhi njengegesi yokuphefumula yokutshuza ngemva kokuxutshwa ne-nitrogen noma i-helium. I-oxygen yezohwebo ingatholakala ngokufaka uketshezi kanye nokukhipha umoya endaweni ezungezile esitshalweni sokuhlukanisa umoya. . Umsebenzi oyinhloko wezimboni we-oxygen ukuvutha. Izinto eziningi ngokuvamile ezingashi emoyeni zingasha kumoya-mpilo, ngakho ukuxuba umoya-mpilo nomoya kuthuthukisa kakhulu ukusebenza kahle kokuvutha ezimbonini zensimbi, ezingezona ayoni, ingilazi kanye nezimboni zikakhonkolo. Ngemuva kokuthi ixutshwe negesi kaphethiloli, isetshenziswa kakhulu ekusikeni, ekushiseleni, ekubhrani nasekuphepheni kwengilazi ukuze kunikeze izinga lokushisa eliphakeme kunokushisa komoya, ngaleyo ndlela kuthuthukiswe ukusebenza kahle. Imithetho yesitoreji: Gcina endaweni epholile, nengena umoya. Gcina kude nomlilo nemithombo yokushisa. Izinga lokushisa lokugcina akufanele lidlule ku-30°C. Kufanele igcinwe ngokuhlukana nezinto ezivuthayo, izimpushana zensimbi ezisebenzayo, njll., futhi ugweme ukugcinwa okuxubile. Indawo yokugcina kufanele ifakwe okokusebenza okuphuthumayo okuvuzayo.

Isicelo:

① Ukusetshenziswa kwemboni:

Ukwenza insimbi, ukuncibilika kwensimbi okungeyona ayoni.Ukusika impahla yensimbi.

②Ukusetshenziswa kwezokwelashwa:

Ekwelashweni kosizo lokuqala lwezimo eziphuthumayo ezifana nokuqunjelwa kanye nesifo senhliziyo, ekwelapheni iziguli ezinezinkinga zokuphefumula kanye ne-anesthesia.

③Ukwenziwa kweSemiconductor:

Ukufakwa komhwamuko wekhemikhali we-silicon dioxide, ukukhula kwe-thermal oxide, i-plasma etching, ukuchithwa kwe-plasma kwe-photoresist kanye negesi ethwalayo emisebenzini ethile yokubeka/yokusabalalisa.

Iphakheji evamile:

Inzuzo:

① Ngaphezu kweminyaka eyishumi emakethe;

②ISO umenzi wesitifiketi;

③Ukulethwa okusheshayo;

④Umthombo wezinto ezingavuthiwe ozinzile;

⑤Isistimu yokuhlaziya eku-inthanethi yokulawula ikhwalithi kuso sonke isinyathelo;

⑥Isidingo esiphezulu kanye nenqubo yokucophelela yokuphatha isilinda ngaphambi kokugcwalisa;
