Lub npe hu ua "Automotive Aub lub teb chaws" ntawm gb29518-2013 "diesel engine nitrogen oxide reducer urea aqueous solution (AUS32)" los ntawm Akxi thiab Lub Chaw Haujlwm Pab Neeg Teb rau lub Tsib Hlis 7, 2013, Lub Xya Hli 1, 2013. Cov txheej txheem no yog tsim los ntawm Ministry of Environmental Protection, los ntawm National Petroleum Products thiab Lubricants Standardization Technical Committee ntawm Petroleum roj thiab lubricants Sub Technical Technical, cov qauv sau ntawv muaj xws li Sinopec Sales Co., Ltd. North China ceg, China Environmental Science Research Lub koom haum, Sinopec Lubricants ceg, PetroChina Muag khoom, CNPC Lanzhou Lubricant Research thiab Development Center,
Sichuan Mei Fung Tshuaj thiab lwm chav nyob.
Cov txheej txheem no txhais cov ntsiab lus thiab txhais cov ntsiab lus, kev qhia, kev xav tau thiab kev xeem, kev soj ntsuam, cov cim, ntim, kev thauj mus los thiab kev cia khoom ntawm nitrogen oxide reductant-urea aqueous solution (AUS32) rau cov cav tov diesel, thiab pom zoo rau kev sib txuas ntawm cov khoom . Cov txheej txheem no pom zoo tias cov kua tshuaj Aureous (AUS32) hais txog kev tsim cov dej hauv Huv, ammonia thiab dej uas tsuas muaj kab, tsis muaj aldehydes thiab lwm yam tshuaj (xws li kev tiv thaiv kab mob), dawb ntawm sulfur thiab sulfide, chlorides, nitrates thiab lwm cov tebchaw.
AUS32 Sau cov twj thiab cov thawv uas ua raws li tus qauv no yuav tsum muaj cov cim nram no: aus32gb29518.
Tus txheej txheem no tseem hais tias, kom tsis txhob AUS32 kev kis kab mob thiab kev txhuam ntawm cov thawv, kav dej, cov nplauv dej, cov khoom sib txuas, cov pa roj carbon dej cawv, thiab lwm yam khoom siv, tshaj. Ua ntej, qee lub nroog mus (los yog ua ntej) qhov kev siv ntawm qhov kev ua haujlwm ntawm lub tsev kawm ntawv heavy duty duty Ⅳ, kev qhia txog ntau lub qauv ntawm cov kev cai hauv zos rau automotive hws, xws li Beijing, Shanghai thiab lwm qhov chaw; nyob rau lub Plaub Hlis 2013, Cov Neeg Suav Cov Xov Xwm ntawm Automobile Engineering tau muab "Automotive Urea Solution Technical Specification" los ntawm lub koom haum.
Tam sim no lub teb chaws tus qauv version gb29518-2013 tso tawm siv, yuav dhau los ua cov kev cai sib txawv. Lub Chaw Saib Xyuas Kev Ncaj Ncees yog pib los ntawm lub teb chaws loj, lub teeb rau kev lag luam kev muag khoom txij li lub Xya Hli 1, 2013 kev siv lub teb chaws Ⅳ Txheem, tab sis lub teb chaws tus qauv ntawm "Automotive Urea cov qauv" tso tawm lub sijhawm ua lag luam ho, qhov tseem ceeb tshaj, lub teb chaws Ⅳ diesel roj tsis tau muaj kev txaus siab nyob hauv lub tebchaws, yog li kev muag khoom ntawm txhua lub teb chaws ntawm kev tsim hluav taws xob rau kev ncua kev siv ntawm lub teb chaws Ⅳ ua kev tsis pom nriav.
