Cov pa oxygen (O2)

Technical parameters

Oxygenyog cov roj uas tsis muaj xim thiab tsis muaj ntxhiab tsw. Nws yog qhov feem ntau cov ntsiab lus ntawm oxygen. Raws li thev naus laus zis muaj kev txhawj xeeb, cov pa oxygen tau muab rho tawm los ntawm cov txheej txheem huab cua liquefaction, thiab cov pa oxygen hauv huab cua yog kwv yees li 21%.Oxygenyog cov roj tsis muaj xim thiab tsis muaj ntxhiab nrog cov tshuaj formula O2, uas yog cov feem ntau ntawm cov pa oxygen. Cov ntsiab lus melting yog -218.4 ° C, thiab qhov kub ntawm -183 ° C. Nws tsis yooj yim soluble hauv dej. Txog 30mL ntawm oxygen yog yaj hauv 1L dej, thiab cov kua oxygen yog ntuj xiav. Cov khoom siv tshuaj lom neeg ntawm cov pa oxygen ntau dua. Tsuas yog cov pa roj tsawg thiab cov hlau tsis tshua muaj kev ua haujlwm xws li kub, platinum, thiab nyiaj, feem ntau ntawm cov ntsiab lus tuaj yeem ua rau cov pa oxygen. Cov tshuaj tiv thaiv no hu ua oxidation reactions. Redox cov tshuaj tiv thaiv yog hais txog cov tshuaj tiv thaiv uas cov hluav taws xob hloov pauv lossis hloov pauv. Oxygen muaj combustion-txhawb thiab oxidizing zog. Kev kho mob cov pa oxygen ua lub luag haujlwm tseem ceeb hauv kev kho mob hauv tsev kho mob thiab kev kho mob, xws li kev phais, kev phais, thiab ntau yam kev kho mob. Oxygen kuj tseem siv tau ua pa ua pa rau kev dhia dej tom qab sib xyaw nrog nitrogen lossis helium. Kev lag luam oxygen tuaj yeem tau txais los ntawm liquefying thiab distilling cov huab cua nyob rau hauv ib puag ncig hauv cov nroj tsuag sib cais cua. . Kev lag luam tseem ceeb ntawm kev siv oxygen yog combustion. Ntau cov ntaub ntawv uas ib txwm tsis tuaj yeem ua rau huab cua tuaj yeem hlawv hauv cov pa oxygen, yog li kev sib xyaw oxygen nrog huab cua zoo heev txhim kho kev sib xyaw ua haujlwm hauv cov hlau, cov hlau tsis muaj hlau, iav thiab pob zeb kev lag luam. Tom qab nws tov nrog roj roj, nws yog dav siv nyob rau hauv kev txiav, vuam, brazing thiab iav tshuab los muab qhov kub thiab txias tshaj huab cua combustion, yog li txhim kho efficiency. Kev ceev faj cia: Khaws rau hauv qhov chaw txias, qhov cua txias. Khaws kom deb ntawm qhov hluav taws kub thiab qhov chaw kub. Qhov kub cia yuav tsum tsis pub tshaj 30 ° C. Nws yuav tsum tau muab cais los ntawm cov khoom siv hluav taws xob, cov hmoov hlau ua haujlwm, thiab lwm yam, thiab tsis txhob sib xyaw cia. Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev.

Daim ntawv thov:

① Kev lag luam siv:

Hlau ua, uas tsis yog-ferrous hlau smelting.Cutting hlau khoom.

② Kev Siv Kho Mob:

Hauv kev pab kho mob ua ntej thaum muaj xwm txheej ceev xws li ua tsis taus pa thiab mob plawv, hauv kev kho mob ntawm cov neeg mob ua pa tsis zoo thiab ua kom tsis muaj zog.
