Kev lag luam tshuaj yog cov cuab yeej siv hauv kev lag luam xws li kws tshuaj, petrochemicals, kev ua liaj ua teb, textiles, thiab ntau yam ntxiv. Lawv yog siv los tsim ntau yam khoom, xws li yas, chiv, detergents, solvents, adhesives, thiab txawm tawg.
5 Qhov Tseem Ceeb Muaj Tshuaj Muaj Tshuaj **
1. **Ammonia (NH3)
Ammonia yog ib qho tseem ceeb hauv kev tsim cov chiv, plastics, textiles, thiab tshuaj ntxuav. Nws yog feem ntau paub txog nws lub luag haujlwm hauv kev ua liaj ua teb ua ib feem tseem ceeb hauv nitrogen-based chiv. Ammonia yog tsim los ntawm cov txheej txheem Haber-Bosch, qhov twg cov pa nitrogen thiab hydrogen gas reacts tshaj lub catalyst ntawm high pressures thiab kub. Cov tshuaj tiv thaiv no synthesizes ammonia, uas yog tom qab ntawd siv rau hauv ntau daim ntawv thov kev lag luam.
Sib nrug los ntawm nws lub luag haujlwm hauv kev ua liaj ua teb, ammonia-based tub yees tshuab tau dav siv hauv kev lag luam khoom noj, tshwj xeeb hauv kev cia txias thiab chaw ua zaub mov. Ammonia cov khoom siv hluav taws xob zoo heev thiab kev siv hluav taws xob ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv cua txias loj.
2. Sulfuric Acid (H2SO4)
Sulfuric acid feem ntau hu ua "tus huab tais ntawm cov tshuaj" vim nws txoj kev siv dav thiab qhov tseem ceeb hauv ntau yam lag luam. Nws yog cov ntxhia pob zeb muaj zog nrog cov khoom corrosive thiab pom cov ntawv thov hauv kev tsim cov chiv, tshuaj ntxuav tes, tshuaj zawv plaub hau, tawg, thiab lwm yam.
Qhov tseem ceeb ntawm kev siv sulfuric acid yog tsim cov phosphoric acid, uas yog ib qho tseem ceeb rau kev tsim phosphatic chiv. Nws kuj tseem siv rau hauv kev ua hlau, roj refining, kev kho dej khib nyiab, thiab kev tsim cov tshuaj ntau yam, suav nrog hydrochloric acid thiab nitric acid.
3. Polyethylene (PE)
Polyethylene yog ib qho ntawm cov yas siv ntau tshaj plaws hauv ntiaj teb. Nws yog ib qho thermoplastic polymer uas muaj cov hlua ntev ntawm ethylene monomers. Polyethylene muaj npe nrov rau nws cov tshuaj tiv thaiv zoo heev, tus nqi qis, kev siv ntau yam, thiab kev ua haujlwm yooj yim, ua rau nws zoo tagnrho rau ntau yam kev siv.
Qhov kev lag luam tshuaj no yog siv rau hauv kev tsim cov khoom ntim, hnab yas, ntim, kav, xaim rwb thaiv tsev, thiab ntau yam khoom siv. Nws yooj, durability, thiab tsis kam mus ya raws ua rau nws haum rau ob qho tib si sab hauv tsev thiab sab nraum zoov daim ntaub ntawv.
4. Chlorine (Cl2)
Chlorine yog ib qho tshuaj lom neeg muaj zog heev uas siv los tsim ntau cov neeg siv khoom thiab cov khoom lag luam. Nws yog feem ntau tsim los ntawm electrolysis ntawm cov tshuaj uas muaj chloride ions, xws li dej ntsev.
Ib qho tseem ceeb ntawm kev siv tshuaj chlorine yog nyob rau hauv kev tsim cov PVC (Polyvinyl Chloride), ib qho ntawm cov khoom siv dav siv hauv ntiaj teb. PVC yog siv rau hauv cov ntaub ntawv siv, hluav taws xob cables, kav dej, thiab cov ntaub pua plag, thiab lwm yam. Cov tshuaj chlorine kuj tseem siv rau hauv cov txheej txheem kho dej, vim nws tua cov kab mob thiab lwm yam kab mob phem.
5. Nitric Acid (HNO3)
Nitric acid yog cov ntxhia muaj zog uas paub txog nws cov khoom oxidizing. Nws yog feem ntau siv rau hauv kev tsim cov chiv, tawg, thiab ntau yam organic tebchaw. Nitric acid feem ntau yog tsim los ntawm cov txheej txheem Ostwald, uas koom nrog oxidation ntawm ammonia.
Hauv kev ua liaj ua teb, nitric acid yog ib qho tseem ceeb hauv kev tsim cov ammonium nitrate chiv, uas muab cov as-ham tseem ceeb rau cov nroj tsuag. Nws kuj tseem ua haujlwm nyob rau hauv kev tsim cov khoom tawg, xws li dynamite thiab TNT, thiab ua tus thawj coj rau ntau yam organic tebchaw siv hauv kev lag luam kws tshuaj.
Xaus
Kev lag luam tshuaj yog lub caj qaum ntawm ntau qhov kev lag luam, ua rau kev tsim khoom ntawm ntau yam khoom uas peb tso siab rau hauv peb lub neej txhua hnub. Ammonia, sulfuric acid, polyethylene, chlorine, thiab nitric acid tsuas yog tsib yam tshuaj tseem ceeb ntawm ntau cov tebchaw nrog ntau hom kev siv.
Los ntawm kev nkag siab txog lub luag haujlwm thiab kev siv ntawm cov tshuaj siv tshuaj no, peb tau txais kev nkag siab rau hauv lub vev xaib sib txawv ntawm cov txheej txheem tshuaj uas ua rau peb lub ntiaj teb niaj hnub no. Txawm hais tias muaj qhov tseem ceeb thiab cov txiaj ntsig uas lawv coj los, nws yog qhov tseem ceeb sib npaug los daws cov tshuaj no kom nyab xeeb thiab muaj lub luag haujlwm kom txo qis qhov cuam tshuam tsis zoo rau tib neeg kev noj qab haus huv thiab ib puag ncig.
