Urea inogona kushandiswa muhuwandu sezvinhu zvakasvibirira kugadzira melamine, urea formaldehyde resin, hydrazine hydrate, tetracycline, Phenobarbital, caffeine, yakaderedzwa brown BR, phthalocyanine B, phthalocyanine Bx, monosodium glutamate uye zvimwe zvigadzirwa.
Iyo ine mhedzisiro inopenya pamakemikari polishing yesimbi uye simbi isina tsvina, uye inoshandiswa se corrosion inhibitor musimbi pickling, pamwe nekugadzirira palladium activation solution.
Muindasitiri, inoshandiswawo seyakabikwa yekugadzira urea formaldehyde resin, polyurethane uye Melamine resin. Apo iyoureainodziya kusvika ku200 ℃, inogadzira melamine yakasimba (kureva cyanuric acid). Izvo zvinobva paCyanuric acid trichloroisocyanuric acid, sodium dichloroisocyanate, tri (2-hydroxyethyl) isocyanurate, tri (Allyl boka) isocyanurate, tri (3,5-di-tert-butyl-4-hydroxybenzyl) isocyanate, tri Glycidol ether ye isocyanic acid. , uye melamine complex yecyanuric acid ine zvakawanda zvakakosha zvinoshandiswa. Iwo maviri ekutanga matsva epamusoro-ekupedzisira ekuuraya utachiona uye mableaches, ane huwandu hwekugadzira huwandu hunodarika 80000 matani e trichloroisocyanuric acid pasi rese.
Sarudzo inodzikisira mumiriri we denitrification yemagetsi ekupisa gasi, pamwe nemotokari urea, inosanganisira 32.5% yakakwirira-kuchena urea uye 67.5% deionized mvura.
Selective Catalytic Reduction (SCR) exhaust post-treatment ndiyo tekinoroji inosarudza inogadzirisa kudzikiswa kwenitrogen oxides (NOx) mumotokari inopedza gasi kuburikidza nepyrolysis reaction yeammonia inogadzirwa neurea mukupisa kwekupisa. Iyo kiyi uye yakajairwa tekinoroji yekudzikisa zvinokuvadza zvinhu zvakaita seNOx mumagasi ekupisa anopisa akadai semaboilers neinjini dzedhiziri. SCR sisitimu inodiwa yekusangana neHyundai Motor Company yemitemo yakasimba yekuburitsa uye mirau, senge Euro IV/Euro V/Euro VI (yenyika IV/national V/national VI) mitemo.Automotive ureainonzi AdBlue muEurope uye DEF muUnited States.
Zvigadzirwa zvemapurasitiki akakosha, kunyanya Urea-formaldehyde, mamwe rabha zvinhu, fetiraiza uye chikafu chekudya, kutsiva antifreeze munyu wakapararira mumugwagwa (mubairo ndewekuti hauparadze simbi), kuwedzera kunhuhwirira kwefodya, kupa maindasitiri Pretzel brown. , imwe shambuu, zvigadziriso zvekugezesa, zvigadzirwa zvefiriji yerubatsiro rwekutanga (nekuti urea inopindirana nemvura kuti itore kupisa), urea yemotokari. kurapwa dhiziri injini, injini Kurasa gasi kubva kumagetsi emagetsi anopisa anogona kunyanya kuderedza nitrogen oxide, kuumbwa kwemvura inosimudzira (yakaoma munyu), inoshandiswa kupatsanura parafini (nekuti urea inogona kugadzira Inclusion compound), refractory zvinhu, kuumbwa kwezvakatipoteredza injini mafuta, kuumbwa kwe mazino chena zvigadzirwa, makemikari fetiraiza, akakosha ebetsero vamiririri pakudhaya uye kudhinda.
