Cov pa oxygen yog ib qho nquag, txawb (muaj qis dua viscosity dua dej) cov xim xiav nrog cov lus qhia paramagnetic. Cov tshuaj no tau txais thaum kawg ntawm lub xyoo pua puv 19, thiab txij thaum ntawd los nws tau pom daim ntawv thov nyob rau hauv ntau lub teb, xws li tshuaj los yog ntau yam lag luam.

Txawm hais tias cov kua oxygen nws tus kheej tsis muaj kev phom sij rau ib puag ncig, tsis tawm cov tshuaj lom, tsis hlawv lossis tawg, ua haujlwm nrog nws yuav tsum ua raws li cov cai tswj kev nyab xeeb. Qhov tseeb yog tias lub ntsiab lus no yog ib qho catalyst rau lub zog oxidation ntawm lwm cov ntaub ntawv, uas yuav ua rau lub ignition los yog tawg ntawm lwm yam khoom nyob rau hauv oxygen-saturated huab cua. Yog li ntawd, qhov chaw uas ua haujlwm yuav tsum tau nruab nrog cov pa cua tswj sensors thiab tshwj xeeb tso pa tawm.

Koj yuav tsum paub tias qhov ntev ntev ntawm huab cua uas muaj cov pa oxygen ntau tuaj yeem ua rau ua pa puas. Kev haus luam yeeb yog txwv tsis pub nyob rau hauv cov chav no thiab, nyob rau hauv txoj cai, qhib nplaim taws tsis tso cai. Cov khaub ncaws ntawm ib tug txiv neej uas ua hauj lwm nyob rau hauv ib tug high-cov ntsiab lus laboxygen nyob rau hauv cov huab cua, yuav tsum tau ventilated rau yam tsawg ib nrab ib teev. Tsis tas li ntawd, thaum siv cov tshuaj no, nws yog ib qho tsim nyog yuav tsum tau ua raws li cov cai tswj kev nyab xeeb rau kev ua haujlwm nrog cov tshuaj cryogenic.

Ib qho teeb meem loj tshaj plaws ntawm cov khoom no yog nws cov khoom siv tub yees, uas ua rau nws nyuaj rau siv thaum ua haujlwm nrog cov ntaub ntawv uas, thaum txias txias, hloov lawv cov yam ntxwv zoo heev. Qhov ntsuas kub ntawm cov pa oxygen ntawm qhov qub atmospheric siab yog -183 ° C. Cov khoom siv tshuaj no khov ntawm -218.8 ° C, tom qab ntawd nws hloov mus ua cov xim xiav daj.

Ua kua oxygen siv:

- ua tus neeg sawv cev oxidizing hauv cov roj foob pob hluav taws, feem ntau ua ke nrog hydrogen lossis kerosene;

- hauv cov tshuaj raws li kev npaj rau kev txhaj tshuaj subcutaneous, rau kev tsim cov pa oxygen cocktails, muab qhov tsim nyog microclimate, refueling ntawm cov cuab yeej tshwj xeeb, hauv kev tsim cov tshuaj los txhim kho kev loj hlob ntawm cov kab mob, thiab lwm yam.;

- hauv kev lag luam engineering, kua oxygen yog siv rau ntau txoj hauv kev vuam, ntog thiab txiav hlau;

- hauv kev lag luam metallurgical nws yog siv los tsim cov hlau, alloys thiab cov hlau tsis muaj hlau, nrog rau kev txo cov hlau;

- siv los txhim kho ib puag ncig: dej huv, rov ua dua cov ntaub ntawv, pov tseg oxidation;

- siv hauv kev lag luam tshuaj rau kev tsim cov oxyliquites (explosives, hauvtam sim no tsis tshua siv), ntau cov kua qaub, acetylene thiab cellulose, nrog rau kev hloov pauv ntawm cov nkev lossis methane.

Qhov twg yuav kua nitrogen thiab oxygen?

Tsis muaj teeb meem yuav tsum tshwm sim nrog kev yuav khoom ntawm cov tshuaj no - cov kua roj ntsha tuaj yeem yuav hauv txhua lub nroog lossis xaj kom xa lawv. Lwm qhov yog tias cov tshuaj no tau muab tso rau hauv lub tog raj kheej loj nrog ntim txog 40 litres, yog li siv hauv tsev koj yuav tsum tau nrhiav lwm txoj hauv kev.
