Ioksijini (O2)

Iiparamitha zobugcisa

Ioksijiniyigesi engenambala nevumba.Yeyona ndlela ixhaphakileyo ye-oxygen.Ngokubhekiselele kwithekhnoloji, i-oksijini ikhutshwa kwinkqubo yokukhutshwa komoya, kwaye i-oksijini emoyeni ithatha malunga ne-21%.Ioksijiniyigesi engenambala kwaye engenavumba kunye nefomula yemichiza i-O2, eyona ndlela ixhaphakileyo ye-oxygen.Indawo yokunyibilika ngu-218.4°C, kwaye indawo yokubila yi-183°C.Ayinyibiliki lula emanzini.Malunga ne-30mL ye-oxygen inyibilika kwi-1L yamanzi, kwaye i-oksijeni engamanzi iluhlaza okwesibhakabhaka.Iimpawu zeekhemikhali zeoksijini zisebenza ngakumbi.Ngaphandle kweegesi ezinqabileyo kunye nezinto zetsimbi ezinomsebenzi ophantsi njengegolide, iplatinam, kunye nesilivere, uninzi lweziqalelo zinokusabela ngeoksijini.Ezi mpendulo zibizwa ngokuba zii-oxidation reactions.Iimpendulo ze-redox zibhekisa kwiimpendulo apho ii-electron zikhutshelwa okanye zitshintshwe.Ioksijini inezixhobo ezixhasa ukutsha kunye ne-oxidizing.Ioksijini yonyango inendima ebalulekileyo kunyango lwesibhedlele kunye nokhathalelo lwezonyango, njengokuvuselela, utyando kunye nonyango olwahlukeneyo.Ioksijini isenokusetyenziswa njengegesi yokuphefumla yokuntywila emva kokuba ixutywe nenitrogen okanye ihelium.Ioksijini yorhwebo inokufumaneka ngokunyibilikisa kunye nokuhluza umoya kwindalo kwisityalo sokwahlula umoya..Ukusetyenziswa kweshishini eliphambili le-oxygen kukutsha.Izinto ezininzi eziqhele ukuvutha emoyeni zinokutshisa ioksijini, ngoko ke ukuxuba ioksijini nomoya kuphucula kakhulu ukusebenza kakuhle kokutsha kwintsimbi, iintsimbi ezingezizo i-ferrous, iglasi kunye namashishini ekhonkrithi.Emva kokuba ixutywe negesi ye-petroli, isetyenziselwa ngokubanzi ukusika, i-welding, i-brazing kunye ne-glass blowing ukubonelela ukushisa okuphezulu kunokushisa komoya, ngaloo ndlela kuphuculwe ukusebenza kakuhle.Amanyathelo okugcina: Gcina kwindawo epholileyo, nengena umoya.Zigcine kude nomlilo kunye nemithombo yobushushu.Ubushushu bokugcina akufunekanga budlule kuma-30°C.Kufuneka igcinwe ngokwahlukileyo kwizinto ezinokutsha, i-powders yensimbi esebenzayo, njl., kwaye ugweme ukugcinwa okuxutywe.Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zonyango olungxamisekileyo oluvuzayo.

Isicelo:

①Ukusetyenziswa koShishino:

Ukwenziwa kwentsimbi, ukunyibilika kwesinyithi esingeyoron.Ukusika izinto zetsimbi.

②Ukusetyenziswa kwezonyango:

Kunyango lokuqala loncedo olungxamisekileyo olufana nokuqunjelwa kunye nokuhlaselwa yintliziyo, kunyango lwezigulana ezinokuphazamiseka kokuphefumla kunye ne-anesthesia.

③Ukwenziwa kweSemiconductor:

Ukubekwa komphunga wekhemikhali wesilicon diokside, ukukhula kwe-thermal oxide, i-plasma etching, ukuhluthwa kweplasma yefotoresist kunye negesi ethwalayo kwimisebenzi ethile yokubeka/yokusasaza.
