Qhov sib txawv ntawm cov khoom sib txawv Marine urea feem ntau yog tshwm sim hauv cov mis, purity thiab siv, cov hauv qab no yog cov lus qhia ntxaws:
Khoom Paub meej
Marine urea feem ntau yog siv los txo nitrogen oxide (NOx) emissions los ntawm lub nkoj tso tawm, kom ntseeg tau tias cov nkoj ua raws li International Maritime Organization (IMO) cov qauv emissions. Hom urea no feem ntau yog siv hauv kev xaiv catalytic txo qis (SCR), thiab cov hauv qab no yog ntau hom thiab cov yam ntxwv ntawm Marine thawv urea:
1. Txheem Marine urea tov
Cov khoom xyaw: Ib qho sib xyaw ntawm urea thiab deionized dej, feem ntau 32.5% urea (xws li AdBlue).
Purity: High purity urea nrog cov ntsiab lus impurity tsawg heev los xyuas kom meej qhov kev ua haujlwm ntawm SCR system thiab lub neej ntawm cov catalyst.
Daim ntawv thov: SCR system rau Marine diesel xyaw kom txo NOx emissions thiab ua raws li IMO Tier III emission qauv.
Nta: Nrog siab solubility thiab stability, haum rau siv nyob rau hauv ntau yam huab cua puag.
2. Lub Freezing point inhibits Marine urea
Cov khoom xyaw: Ntxiv cov tshuaj tiv thaiv kab mob rau cov txheej txheem Marine urea daws kom txo qhov khov ntawm lub thawv urea tov.
Purity: Nws kuj yog siab purity urea, thiab cov tshuaj tiv thaiv kab mob ntxiv yuav tsum tau ua raws li cov cai ntawm SCR system.
Txoj Kev: Siv rau cov nkoj ua haujlwm hauv cov huab cua txias kom ntseeg tau tias cov tshuaj urea tsis khov ntawm qhov kub qis.
Nta: anti-freezing nyhuv yog qhov tseem ceeb, haum rau siv nyob rau hauv lub polar los yog dej hiav txwv cheeb tsam.
3. Siab concentration ntawm Marine urea
Muaj pes tsawg leeg: urea tov nrog siab dua tus qauv concentration (xws li 40% urea tov).
Purity: Siab purity, ua tau raws li cov kev cai nruj ntawm SCR system.
Siv: Rau cov nkoj uas muaj qee qhov kev xav tau tshwj xeeb, uas tej zaum yuav tsum tau ua raws li cov kev cai tshwj xeeb ntawm lub nkoj thiab lub cav tsim khoom.
Nta: Cov concentration siab dua txo qhov ntim ntawm kev thauj mus los thiab khaws cia, tab sis yuav tsum tau tuav kom zoo thiab siv cov khoom siv.
Xaiv lub hauv paus ntawm cov khoom sib txawv Marine urea
Climatic tej yam kev mob: Nkoj ua hauj lwm nyob rau hauv lub txias cheeb tsam yuav tsum tau siv freezing point tsub kom Marine urea kom tsis txhob muaj teeb meem icing.
Cov qauv emission: Tag nrho cov khoom siv Marine urea yuav tsum ua raws li IMO emission standard, tab sis qhov kev xaiv nyob ntawm lub nkoj SCR system tsim thiab cov chaw tsim khoom cov lus pom zoo.
Kev khiav hauj lwm ib puag ncig: Raws li qhov chaw caij nkoj thiab chaw ua haujlwm ntawm lub nkoj, cov khoom tsim nyog ntim urea hom raug xaiv los xyuas kom meej qhov kev ua tau zoo thiab kev ua haujlwm zoo.
Qhov zoo ntawm peb lub tuam txhab hauv Marine urea ntau lawm
Cov khoom lag luam zoo: Peb tsim Marine urea nrog cov purity siab thiab tsis muaj impurity cov ntsiab lus, ua kom muaj kev ua haujlwm zoo thiab kev ruaj ntseg ntev ntawm SCR systems.
Advanced thev naus laus zis: Kev siv cov thev naus laus zis ntau lawm thiab cov cuab yeej siv los ua kom cov khoom ruaj khov zoo, raws li cov qauv thoob ntiaj teb.
Kev Pabcuam Zoo: Muab kev txhawb nqa kev tshaj lij thiab kev pabcuam tomqab muag los pab cov neeg siv khoom daws txhua yam teebmeem tshwm sim hauv kev siv.
Kev koom tes mus sij hawm ntev: Raws li lub sijhawm ntev OEM tus khub ntawm Sinopec thiab Mercedes-Benz, peb muaj kev paub nplua nuj thiab lub koob npe nrov los xyuas kom muaj kev ntseeg siab thiab txaus siab ntawm cov neeg siv khoom.
Yog tias koj muaj kev xav tau tshwj xeeb lossis cov lus nug txog Marine urea khoom, thov koj xav tiv tauj peb.
