Ioksijini (O2)

Iiparameter zobugcisa

Ioksijiniyigesi engenambala nengenavumba. Yeyona ndlela ixhaphakileyo ye-oksijini. Ngokuphathelele ubuchwepheshe, i-oksijini ikhutshwa kwinkqubo yokunyibilika komoya, kwaye i-oksijini esemoyeni ithatha malunga ne-21%.Ioksijiniyigesi engenambala nengenavumba enefomyula yekhemikhali i-O2, eyona ndlela ixhaphakileyo ye-oxygen. Indawo yokunyibilika yi--218.4°C, kwaye indawo yokubila yi--183°C. Ayinyibiliki lula emanzini. Malunga ne-30mL ye-oxygen iyanyibilika kwi-1L yamanzi, kwaye i-oxygen engamanzi iluhlaza okwesibhakabhaka. Iipropati zekhemikhali ze-oxygen zisebenza ngakumbi. Ngaphandle kweegesi ezingaqhelekanga kunye nezinto zesinyithi ezinemisebenzi ephantsi njengegolide, iplatinum, kunye nesilivere, uninzi lwezinto zinokusabela kunye ne-oxygen. Ezi mpendulo zibizwa ngokuba zii-oxidation reactions. Iimpendulo ze-Redox zibhekisa kwiimpendulo apho ii-electron zidluliselwa okanye zitshintshwa khona. I-oxygen ineempawu zokuxhasa ukutsha kunye ne-oxidation. I-oxygen yezonyango idlala indima ebalulekileyo kunyango lwesibhedlele kunye nokhathalelo lweklinikhi, njengokuvuselela, utyando, kunye nonyango olwahlukeneyo. I-oxygen ingasetyenziselwa njengegesi yokuphefumla yokuntywila emva kokuxutywa ne-nitrogen okanye i-helium. I-oxygen yezorhwebo ingafunyanwa ngokunyibilikisa kunye nokunyibilikisa umoya okwindawo engqongileyo kwisityalo sokwahlula umoya. . Ukusetyenziswa okuphambili kwe-oxygen kwimizi-mveliso kukutsha. Izinto ezininzi ezingatshiyo emoyeni zinokutsha kwioksijini, ngoko ke ukuxuba ioksijini nomoya kuphucula kakhulu ukusebenza kakuhle kokutsha kwimizi-mveliso yentsimbi, iintsimbi ezingenayo i-ferrous, iglasi kunye nekhonkrithi. Emva kokuba ixutywe negesi yepetroli, isetyenziswa kakhulu ekusikeni, ekudibaniseni, ekutshiseni nasekuvutheleni iglasi ukuze kubonelelwe ngobushushu obuphezulu kunokutsha komoya, ngaloo ndlela kuphucula ukusebenza kakuhle. Amanyathelo okugcina: Gcina kwindawo yokugcina izinto epholileyo, enomoya opholileyo. Gcina kude nomlilo kunye nemithombo yobushushu. Ubushushu bokugcina akufuneki budlule kwi-30°C. Kufuneka igcinwe ngokwahlukileyo kwizinto ezinokutsha, iipowder zesinyithi ezisebenzayo, njl.njl., kwaye uphephe ukugcina okuxutyiweyo. Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zonyango olungxamisekileyo oluvuzayo.

Isicelo:

①Ukusetyenziswa kweShishini:

Ukwenziwa kwentsimbi, ukunyibilikisa isinyithi esingenasinyithi. Izinto zesinyithi ezisikiweyo.

②Ukusetyenziswa kwezonyango:

Kunyango loncedo lokuqala kwiimeko ezingxamisekileyo ezifana nokufuthaniseka kunye nokuhlaselwa yintliziyo, kunyango lwezigulana ezineengxaki zokuphefumla nakwi-anesthesia.

③Ukwenziwa kweSemiconductor:

Ukufakwa komphunga wekhemikhali we-silicon dioxide, ukukhula kwe-thermal oxide, ukugrumba kwe-plasma, ukuhluthwa kwe-photoresist kwi-plasma kunye negesi yokuthwala kwimisebenzi ethile yokufakwa/ukusasazwa.
