Cov piv txwv ntawm kev lag luam gases yog dab tsi?
Industrial gases, tseem hu ua bulk gases lossis cov khoom lag luam gases, yog cov pa roj uas tsim los ntawm cov nplai loj rau cov ntawv thov kev lag luam. Lawv ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam, xws li kev tsim cov hlau mus rau kev kho mob. Hauv tsab xov xwm no, peb yuav tshawb txog qee qhov piv txwv ntawm kev lag luam gases thiab lawv cov kev siv.
1. Nitrogen:
Nitrogen yog cov pa roj ntau tshaj plaws hauv huab cua, suav txog li 78% ntawm huab cua peb ua pa. Nws yog dav siv raws li ib tug industrial gas vim nws inertness thiab siab purity. Nitrogen yog siv rau hauv kev lag luam khoom noj thiab dej haus los khaws cov khoom tshiab, tiv thaiv kev lwj, thiab ua kom cov khoom muaj kev nyab xeeb. Nws kuj yog siv nyob rau hauv kev lag luam electronics rau soldering thiab raws li ib tug tiv thaiv roj nyob rau hauv cov txheej txheem tshuaj.
2. Cov pa oxygen:
Oxygen yog lwm qhov tseem ceeb ntawm kev lag luam roj. Nws yog siv nyob rau hauv ntau yam kev siv, xws li combustion, oxidation, thiab raws li ib tug raw khoom rau tshuaj ntau lawm. Hauv kev lag luam steel, cov pa oxygen yog siv los txhim kho qhov ua tau zoo ntawm cov tshuab hluav taws xob tawg thiab txo cov pa hluav taws xob hauv tsev cog khoom. Hauv kev kho mob, cov pa oxygen yog siv rau kev txhawb nqa kev ua pa thiab kev siv tshuaj loog.
3. Cov pa roj carbon dioxide:
Cov pa roj carbon dioxide yog ntau yam kev lag luam roj uas pom cov ntawv thov hauv ntau qhov kev lag luam. Nws yog feem ntau siv hauv kev lag luam zaub mov thiab dej haus rau carbonation, ua cov tub yees, thiab ua cov roj inert kom ntev lub neej txee ntawm cov khoom ntim. Cov pa roj carbon dioxide kuj tseem siv rau hauv kev lag luam roj thiab roj rau kev txhim kho cov roj rov qab thiab ua hluav taws tua hluav taws.
4. Argon:
Argon yog cov roj uas tsis muaj ntxhiab thiab tsis muaj xim uas paub txog nws qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Nws yog feem ntau siv los ua cov roj tiv thaiv hauv kev siv vuam los tiv thaiv oxidation thiab txhim kho vuam zoo. Argon kuj tseem siv rau hauv kev lag luam semiconductor rau purging thiab plasma etching txheej txheem. Hauv kev lag luam teeb pom kev zoo, argon yog siv rau hauv cov qij fluorescent thiab lwm cov roj tso tawm.
5. Hydrogen:
Hydrogen yog cov roj huv huv uas tau txais koob meej raws li lub zog tauj dua tshiab. Nws yog siv nyob rau hauv ntau yam kev lag luam, xws li hydrogenation, refining, thiab raws li ib tug txo tus neeg sawv cev nyob rau hauv metallurgy daim ntaub ntawv. Hydrogen kuj tseem siv rau hauv kev lag luam khoom noj rau hydrogenation ntawm cov roj zaub thiab ua ib qho chaw tiv thaiv hauv ntim.
6. Helium:
Helium yog lub teeb, tsis-flammable gas paub txog nws qhov ntom ntom thiab siab thermal conductivity. Nws yog dav siv nyob rau hauv cryogenics, raws li nws yuav ua tau liquefied ntawm tsis tshua muaj kub. Helium feem ntau yog siv rau hauv kev kho mob ua kom txias superconducting hlau nplaum hauv MRI tshuab. Nws kuj tseem siv rau hauv kev lag luam aerospace rau kev siv zog thiab purging tshuab.
7. Acetylene:
Acetylene yog ib qho hluav taws kub heev uas siv rau hauv ntau yam kev lag luam, feem ntau rau vuam thiab txiav hlau. Nws muab cov nplaim hluav taws kub kub, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum muaj cov cua kub kom muaj zog. Acetylene kuj tseem siv rau hauv kev lag luam tshuaj rau kev tsim cov organic tebchaw.
8. Ammonia:
Ammonia yog cov roj tsis muaj xim nrog cov ntxhiab tsw. Nws yog feem ntau siv los ua cov tub yees hauv kev lag luam thiab kev lag luam txias tshuab. Ammonia kuj tseem siv rau hauv kev tsim cov chiv, tshuaj ntxuav, thiab tshuaj. Hauv kev lag luam textile, ammonia yog siv rau dyeing thiab desizing fabrics.
9. Cov tshuaj chlorine:
Chlorine yog cov roj reactive heev uas tau siv dav los ua cov tshuaj tua kab mob hauv kev kho dej thiab kev huv. Nws kuj tseem siv rau hauv kev tsim cov PVC, cov kuab tshuaj, thiab ntau yam organic tebchaw. Chlorine-based compounds yog siv rau hauv kev lag luam kws tshuaj rau kev tsim tshuaj thiab hauv kev lag luam ua liaj ua teb ua tshuaj tua kab.
10. Sulfur Dioxide:
Sulfur dioxide yog cov pa roj lom uas feem ntau siv los tsim cov sulfuric acid. Nws kuj yog siv los ua cov khoom noj khoom haus hauv cov zaub mov thiab cawv. Sulfur dioxide muaj cov khoom bleaching thiab yog siv nyob rau hauv daim ntawv thiab textile kev lag luam rau bleaching fibers thiab tshem tawm xim.

Industrial gases ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw thiab muaj ntau yam kev siv. Tsab ntawv xov xwm no tau muab cov ntsiab lus ntawm qee qhov piv txwv ntawm kev lag luam gases thiab lawv siv hauv kev lag luam xws li zaub mov thiab dej haus, kev kho mob, kev tsim khoom, thiab lub zog. Nws yog ib qho tseem ceeb uas yuav tau tswj cov roj av nrog kev saib xyuas, vim tias lawv tuaj yeem ua rau muaj kev phom sij yog tias siv tsis raug.
