Thaum cov neeg feem coob hnov lo lus "sulfuric acid," lawv pom cov fuming, pungent kua nyob rau hauv lub chav kuaj beaker. Tab sis cov tshuaj tseem ceeb no yog ntau dua li cov tshuaj reagent - nws yog ib tsev neeg ntawm cov khoom sib txawv nrog ntau qib thiab cov ntawv thov uas kov txhua qhov kev lag luam niaj hnub no. Cia peb ua tib zoo saib qhov tsis tseem ceeb ntawm "ntau- cuab yeej" ntawm lub ntiaj teb kev lag luam.
1. Tsev Neeg Sulfuric Acid: Qib rau txhua qhov xav tau
Muaj -Qib Sulfuric Acid
Qhov sib txawv tshaj plaws, feem ntau ntawm qhov concentration ntawm ib ncig ntawm 98%. Nws yog ib qho tseem ceeb ntawm cov khoom siv raw hauv kev lag luam tshuaj, nrog rau kev siv dav hauv kev tsim cov chiv, kev ua hlau, roj av refining, thiab lwm yam. Cov qauv nruj hauv teb chaws tswj hwm nws cov kev txwv tsis pub muaj kev txwv kom ua kom zoo ib yam.
Roj teeb -Qib Sulfuric Acid
Tshwj xeeb tsim los rau cov hmoov lead-acid roj teeb, qib no xav tau qhov zoo tshaj plaws purity. Cov impurities xws li hlau, manganese, thiab chlorine yuav tsum tau khaws cia rau cov kab mob kom tsis txhob muaj kev puas tsuaj ntawm cov roj teeb kev ua haujlwm thiab lub neej ntev. Qhov no yog cov electrolyte uas powers lub roj teeb nyob rau hauv peb lub tsheb, hluav taws xob tsheb, thiab backup fais fab system.
Reagent -Qib Sulfuric Acid
Tsim los rau kev kuaj thiab tshuaj chemistry daim ntawv thov, qib no muaj nyob rau hauv ntau qib purity - suav nrog lav reagent, tshuaj ntsuam reagent, thiab tshuaj dawb huv. Nws ua lub luag haujlwm tseem ceeb hauv kev tshuaj R & D, kev saib xyuas ib puag ncig, thiab kev kuaj xyuas zaub mov.
Electronic-Qib Sulfuric Acid
Cov tswv cuab "noble" ntawm tsev neeg sulfuric acid, qhov no ultra- siab- qib purity yog siv tshwj xeeb hauv kev tsim khoom semiconductor. Nrog rau qib purity mus txog 99.999999% (8N) lossis siab dua, nws tsis muaj cov hlau ions lossis cov khoom siv, ua rau nws tseem ceeb rau kev ntxuav wafer, photolithography, thiab lwm yam haujlwm tseem ceeb- cov txheej txheem tseem ceeb.
2. Lub cev ntawm cov khoom siv sulfuric acid
Concentrated sulfuric acid
Feem ntau nyob ib ncig ntawm 98% concentration, daim ntawv no pom muaj zog lub cev qhuav dej thiab oxidizing zog. Nws yog daim ntawv tshaj plaws rau kev khaws cia thiab kev thauj mus los.
Dilute sulfuric acid
Xws li ntawm 20% mus rau 70% concentration, daim ntawv no muaj tsawg corrosivity thiab yog dav siv nyob rau hauv cov hlau nto kho, kho pH, thiab zoo xws li daim ntaub ntawv.
Oleum (Fuming Sulfuric Acid)
Ib qho kev daws teeb meem ntawm sulfur trioxide hauv sulfuric acid, oleum tso tawm cov yam ntxwv "dawb pa taws" hauv huab cua. Nrog nws cov kev ua kom zoo dua qub, nws feem ntau yog siv hauv cov organic synthesis thiab sulfonation cov tshuaj tiv thaiv.
3. Kev siv thoob plaws hauv kev lag luam
Ua liaj ua teb
Sulfuric acid yog cov khoom siv tseem ceeb hauv kev tsim cov phosphate chiv xws li ammonium phosphate thiab superphosphate, muab cov phosphorus tseem ceeb rau cov qoob loo thiab ua lub luag haujlwm tseem ceeb hauv kev ruaj ntseg khoom noj hauv ntiaj teb.
Kev tsim khoom lag luam
Hauv kev ua hlau, nws yog siv rau steel pickling kom tshem tawm oxide nplai. Hauv kev lag luam textile, nws ua haujlwm tseem ceeb hauv kev dyeing thiab xov. Nyob rau hauv cov roj av sector, nws yog ua hauj lwm nyob rau hauv lub refining ntawm roj av thiab lubricants.
Lub Neej Txhua Hnub
Los ntawm cov roj teeb tsheb mus rau cov neeg ua haujlwm tu tsev, los ntawm kev kho dej hauv nroog mus rau kev tsim khoom noj khoom haus ntxiv, sulfuric acid pom nws txoj hauv kev rau ntau yam hauv peb lub neej txhua hnub - feem ntau peb tsis paub nws.
High-Tech Industries
Advanced sectors xws li semiconductor nti fabrication, lithium-ion roj teeb recycling, thiab tsawg lub ntiaj teb rho tawm tag nrho nyob ntawm siab -purity tshwj xeeb sulfuric acid cov khoom los tsav innovation.
4. Kev tuav ruaj ntseg thiab khaws cia
Raws li cov tshuaj muaj zog corrosive, sulfuric acid xav tau cov txheej txheem kev nyab xeeb nruj:
Ib txwm ua raws li cov txheej txheem kev khiav hauj lwm thiab hnav cov khoom tiv thaiv tus kheej tsim nyog.
Khaws rau hauv cov kua qaub- cov thawv uas tiv taus, thiab zam kev sib cuag nrog cov hlau, cov khoom siv organic, thiab cov khoom tsis sib xws.
Thaum diluting,ib txwm ntxiv acid rau dej- yeej tsis thim rov qab - los tiv thaiv kev sib tsoo hnyav.
Nyob rau hauv cov ntaub ntawv ntawm nchuav, neutralize nrog alkaline cov ntaub ntawv thiab yaug kom huv si nrog dej ntau.
Kaw Xav
Los ntawm cov khoom noj khoom haus ntau rau ultra- cov tshuaj siv hluav taws xob ntshiab, tsev neeg sulfuric acid tau woven nws tus kheej rau hauv cov ntaub ntawm kev vam meej niaj hnub no. Kev nkag siab txog nws cov qib sib txawv, cov ntaub ntawv, thiab cov ntawv thov tsis tsuas yog ua rau peb txaus siab rau cov tshuaj tseem ceeb no tab sis kuj ua kom peb daws nws nyab xeeb thiab ua tau zoo hauv txhua qhov kev siv.
