Adblue Qib Urea rau ua AdBlue kua
Txhua yam hais txog DEF
Txij li thaum xyoo 2010 dhau los ntawm tsoomfwv cov cai nruj dua ntawm nitrogen oxide (NOx) emissions hauv cov tsheb tshiab, kev siv
emission-txo tshuab tau skyrocketed.Txog tam sim no qhov nrov tshaj plaws ntawm cov thev naus laus zis no yog Selective Catalytic Reduction (SCR), uas yuav tsum tau siv cov tshuaj hu ua DEF.
DEF yog dab tsi?
Diesel Exhaust Fluid, los yog DEF, yog cov tshuaj purity urea-raws li tsim los txo NOx emissions hauv cov tsheb tshiab.NOx yog cov pa phem uas ua rau muaj cov pa phem thiab cov kua qaub los nag, uas tuaj yeem ua rau peb noj qab haus huv thiab ib puag ncig.
DEF yog tsim los siv rau hauv diesel xyaw nrog SCR thev naus laus zis.Thaum DEF raug txhaj rau hauv qhov tso pa tawm ntawm SCR-nruab nrog lub tshuab hluav taws xob, nws cuam tshuam nrog lub catalyst txhawm rau rhuav tshem NOx molecules rau hauv tsis muaj nitrogen thiab dej.
DEF yog ib qho tshuaj tsw qab, tsis muaj xim, tsis muaj nplaim taws thiab tsis muaj kuab lom uas tsis muaj kev phom sij rau tib neeg, khoom siv thiab ib puag ncig.High-purity DEF tau nce ntau thoob plaws hauv Asmeskas los ntawm cov tuam txhab xws li Airgas, uas muab cov khoom siv ultra-ntshiab Airgas AiRx DEF.
SCR Technology
Selective Catalytic Reduction, los yog SCR, yog tus thawj coj emissions tswj tshuab muaj rau diesel xyaw.SCR systems siv lub catalytic converter, nrog rau qhov sib ntxiv ntawm DEF, txhawm rau NOx emissions.
DEF tsis yog ib qho roj ntxiv, tab sis ib qho kev sib cais tag nrho uas nyob hauv nws lub tank.Ua ntej, nws yog txhaj ncaj qha mus rau hauv cov kwj deg, qhov twg nws yog ces vaporized los ntawm ib tug catalyst, tsim ammonia.Los ntawm qhov ntawd, ammonia ua haujlwm nrog SCR catalyst los hloov NOx emissions tsis zoo rau hauv nitrogen thiab dej tsis zoo.
FAQs

Q: Yuav ua li cas txog qhov siv tau ntawm cov khoom?
A: Peb xyuas kom meej tias cov khoom thauj muaj 80% lub neej txee thaum nws xa khoom.
Q: Cov ntaub ntawv twg koj muab?
A: Feem ntau, peb muab Daim Ntawv Pov Thawj Ua Lag Luam, Cov Ntawv Teev Npe, Daim Ntawv Sau Npe, COA thiab Daim Ntawv Pov Thawj Keeb Kwm.Yog tias koj lub lag luam muaj cov kev cai tshwj xeeb, thov hu rau peb paub.
