Automotive Qib UREA

Automotive qib urea yog siv rau kev kho tsheb tsheb, thiab nws tau decomposed rau hauv ammonia roj los ntawm kev siv cov khib nyiab cua sov ntawm cov yeeb nkab tso tawm thiab tom qab ntawd ua ke nrog nitrogen oxides rau ib lub sij hawm los tsim nitrogen, oxygen, thiab dej.

Lub Hnub Qub Grace tau tsim nyob rau xyoo 2003 los tsim thiab xa tawm cov khoom siv tshuaj rau chiv, pub additives, thiab kev lag luam qib kev siv. Muaj peev xwm npaj cov nkoj tawg ntau thiab tuav cov thawv ntim nrog ib ncig ntawm 50, 000 tons ntawm ntim rau Latin American lag luam, 40, 000 tons rau cov teb chaws Asia, thiab lwm yam. Hu rau peb kom paub ntau ntxiv.

Automotive Qib Urea siv rau dab tsi?

Automotive qib urea yog siv rau kev kho tsheb tsheb, thiab nws tau decomposed rau hauv ammonia roj los ntawm kev siv cov khib nyiab cua sov ntawm cov yeeb nkab tso tawm thiab tom qab ntawd ua ke nrog nitrogen oxides rau ib lub sij hawm los tsim nitrogen, oxygen, thiab dej. DEF yog txhaj rau hauv cov dej ntws ntawm cov cav diesel, qhov uas nws hnov ​​​​mob nrog cov teeb meem nitrogen oxides (NOx) tsim thaum lub sij hawm combustion. DEF yog txhaj rau hauv cov dej ntws ntawm cov cav diesel, qhov uas nws hnov ​​​​mob nrog cov teeb meem nitrogen oxides (NOx) tsim thaum lub sij hawm combustion.

Qhov tshwm sim tshwm sim hloov NOx rau hauv cov pa roj nitrogen thiab dej vapor, uas muaj kev nyab xeeb rau ib puag ncig. Qhov no yog tag nrho ib feem ntawm cov txheej txheem hu ua selective catalytic reduction (SCR), uas tau dhau los ua qhov tseem ceeb hauv kev lag luam tsheb.

Automotive qib urea yog ib qho tseem ceeb ntawm cov tshuab hluav taws xob niaj hnub uas ua tau raws li cov qauv emissions tshiab. Nws yog siv rau ntau yam tsheb hnyav, nrog rau cov tsheb thauj mus los, tsheb npav, thiab cov tshuab ua liaj ua teb. DEF kuj tseem siv rau hauv cov tsheb thauj neeg, SUVs, thiab cov tsheb thauj khoom nrog lub cav diesel.

Kev siv automotive qib urea yog ib kauj ruam tseem ceeb hauv kev txo cov roj tsev cog khoom thiab kev cuam tshuam ntawm tib neeg kev ua ub no rau ib puag ncig. Nws pab txhim kho huab cua zoo thiab txo cov smog, tsim kom muaj lub ntiaj teb huv thiab noj qab haus huv rau txhua tus neeg nyiam.

Automotive qib urea pab tsim kom muaj ib puag ncig huv thiab nyab xeeb rau peb txhua tus, thiab nws qhov tseem ceeb hauv kev lag luam tsheb tsuas yog txuas ntxiv mus rau xyoo tom ntej.
