Lwm qhov tshwj xeeb ntawm kev ntim khoom tuaj yeem muab tau raws li cov neeg siv khoom xav tau

Tuam Tshoj ua kua oxygen flammable tsum

Cov pa oxygen, cov kua ua kua cryogenic nrog qhov kub ntawm -183 ° C, yog siv dav hauv ntau yam lag luam rau nws cov khoom oxidizing. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nkag siab tias txawm hais tias cov kua oxygen nws tus kheej tsis yog nplaim taws, nws ua kom nrawm nrawm ntawm lwm yam khoom.

CovFlammability ntawm Liquid Oxygen: Ua kom muaj kev nyab xeeb hauv kev lag luam

Cov pa oxygen, cov kua ua kua cryogenic nrog qhov kub ntawm -183 ° C, yog siv dav hauv ntau yam lag luam rau nws cov khoom oxidizing. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nkag siab tias txawm hais tias cov kua oxygen nws tus kheej tsis yog nplaim taws, nws ua kom nrawm nrawm ntawm lwm yam khoom. Txhawm rau kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab txo qhov kev pheej hmoo ntawm kev raug xwm txheej, nws yog ib qho tseem ceeb kom paub peb tus kheej nrog cov kev phom sij thiab ua raws li kev ceev faj txog kev nyab xeeb thaum cuam tshuam nrog cov pa oxygen.

Los ntawm peb cov kev ua haujlwm nyuaj, peb ib txwm ua nyob rau hauv pem hauv ntej ntawm cov khoom siv technology tshiab. Peb yog tus khub ntsuab koj tuaj yeem tso siab rau. Tiv tauj peb hnub no kom paub ntau ntxiv!

Nkag siab txog Hazards:

Cov pa oxygen ua kua ua kom muaj kev sib txuas los ntawm kev muab cov ntsiab lus ntawm cov pa oxygen, uas txhawb oxidation sai. Thaum cov cuab yeej no muaj cov ntawv thov kev lag luam tseem ceeb, nws kuj ua rau muaj kev pheej hmoo loj. Cov ntaub ntawv uas feem ntau tsis yog-flammable los yog me ntsis combustible tuaj yeem ignite hnyav nyob rau hauv muaj kua oxygen. Organic compounds, fuels, oils, grease, thiab txawm tias qee cov hlau ua tau zoo heev thiab tuaj yeem ua rau tawg yog tias tsis ua haujlwm zoo.

Kev Tiv Thaiv Kev Nyab Xeeb:

1. Kev Cia Zoo: Cov pa oxygen yuav tsum tau muab cia rau hauv cov thawv ntim khoom tshwj xeeb tsim rau cov kua dej cryogenic. Cov thawv no yuav tsum muaj qhov cua zoo kom tiv thaiv kom tsis txhob muaj oxygen nplua nuj nyob hauv huab cua. Cov chaw cia khoom yuav tsum tau nruab nrog lub tshuab hluav taws xob tua hluav taws thiab tshuaj xyuas tsis tu ncua rau cov dej xau.

2. Cov txheej txheem tuav: Cov neeg ua hauj lwm nrog cov pa oxygen yuav tsum tau kawm txaus txog nws cov khoom, cov txheej txheem tuav, thiab cov txheej txheem xwm txheej ceev. Cov cuab yeej tiv thaiv tus kheej suav nrog cov khaub ncaws tiv thaiv hluav taws, hnab looj tes, tsom iav, thiab daim npog ntsej muag yuav tsum hnav txhua lub sijhawm. Txhua yam khoom siv hauv kev sib cuag nrog cov pa oxygen yuav tsum tau ua los ntawm cov ntaub ntawv uas paub tias tsis yog-reactive, xws li stainless hlau lossis txhuas.

3. Oxygen Concentration Monitoring: Cov cheeb tsam uas muaj cov pa oxygen ua kua los yog khaws cia yuav tsum tau saib xyuas kom tsis tu ncua ntawm cov pa oxygen concentration. Oxygen sensors thiab gas detectors yuav tsum tau muab ntsia kom sai li sai tau txheeb xyuas cov pa xau lossis oxygen-enriched cua. Kev cob qhia tsis tu ncua ntawm kev siv cov cuab yeej saib xyuas no yog qhov tseem ceeb los xyuas kom meej tias lawv txoj haujlwm txhim khu kev qha.

4. Kev Tiv Thaiv Hluav Taws Xob: Txij li thaum cov pa oxygen ua kom nrawm nrawm, kev tiv thaiv hluav taws yog qhov tseem ceeb tshaj plaws. Txoj cai txwv tsis pub haus luam yeeb, tswj kev nkag mus rau thaj chaw khaws cia, thiab txwv tsis pub cov khoom siv hluav taws xob nyob ib puag ncig yog qhov tseem ceeb. Cov khoom siv hluav taws xob kuj tseem yuav tsum tau tsim tshwj xeeb kom txo qis qhov kev pheej hmoo ntawm qhov ci ntsa iab.

Kev Siv Hluav Taws Xob:

Txawm hais tias muaj kev pheej hmoo cuam tshuam, kua oxygen ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam, suav nrog kev tsim steel, kev tsim tshuaj lom neeg, aerospace, thiab kev kho mob. Steelmakers siv cov kua oxygen los txhim kho cov combustion ntawm impurities, ua kom huv si thiab muaj zog hlau. Hauv kev kho mob, kua oxygen yog siv los muab kev kho mob oxygen ntxiv rau cov neeg mob ua pa.

Xaus:

Thaum cov pa oxygen ua kua muaj txiaj ntsig zoo thoob plaws ntau qhov kev lag luam, nws cov peev xwm flammability yuav tsum tsis txhob kwv yees. Los ntawm kev nkag siab txog cov khoom muaj kev phom sij, ua raws li cov txheej txheem kev nyab xeeb nruj, thiab ua kom ruaj khov thiab tuav kom zoo, peb tuaj yeem txo cov kev pheej hmoo cuam tshuam nrog cov pa oxygen. Cov kws tshaj lij hauv kev lag luam yuav tsum ua qhov tseem ceeb ntawm kev nyab xeeb thiab tsis tu ncua qhia lawv tus kheej thiab lawv pab pawg ntawm cov txheej txheem tsim nyog kom muaj kev nyab xeeb ua haujlwm thiab tiv thaiv kev raug mob.

Tau ntau xyoo, nrog cov khoom lag luam zoo, kev pabcuam thawj zaug, tus nqi qis qis peb yeej koj ntseeg thiab nyiam ntawm cov neeg siv khoom. Tam sim no peb cov khoom muag thoob plaws hauv lub tebchaws thiab txawv teb chaws. Ua tsaug rau cov neeg siv khoom tsis tu ncua thiab kev txhawb nqa tshiab. Peb muab cov khoom lag luam zoo thiab tus nqi sib tw, txais tos cov neeg siv khoom tsis tu ncua thiab tshiab koom tes nrog peb!
