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 seyakagadzirwa kugadzira 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 ekupedzisira-ekupedzisira ekuuraya hutachiona 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 kudzikisa 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 mumoto unopisa gasi senge boilers uye dizeli injini.SCR sisitimu inodiwa yekusangana neHyundai Motor Company yemitemo yakasimba yekuburitsa uye mirau, senge Euro IV/Euro V/Euro VI (yenyika IV/nyika V/nyika VI) mitemo.Automotive ureainonzi AdBlue muEurope uye DEF muUnited States.
Zvigadzirwa zvemapurasitiki akakosha, kunyanya Urea-formaldehyde, mamwe rabha zvinhu, fetiraiza uye chikafu zvinosanganisa, kutsiva antifreeze munyu wakapararira mumugwagwa (mubairo ndewekuti hauparadze simbi), ichiwedzera kunhuwa kwefodya, ichipa maindasitiri Pretzel brown. , imwe shampoo, detergent ingredients, zvigadzirwa zvefirst-aid firiji pasuru (nokuti urea inopindirana nemvura kuti itore kupisa), mota urea kurapwa dhiziri injini, injini Gasi rinosvibisa kubva kumagetsi emagetsi rinopisa rinogona kunyanya kuderedza nitrogen oxide, kuumbwa kweanosimudzira mvura (complex). munyu), inoshandiswa kupatsanura parafini (nokuti urea inogona kuumba Inclusion compound), refractory zvinhu, kuumbwa kwezvakatipoteredza injini mafuta, kuumbwa kwemazino ekuchenesa zvigadzirwa, makemikari fetiraiza, akakosha ebetsero vamiririri pakudhaya uye kudhinda.
