I-Urea ingasetshenziswa ngobuningi njengento eluhlaza ekukhiqizeni i-melamine, i-urea formaldehyde resin, i-hydrazine hydrate, i-tetracycline, i-Phenobarbital, i-caffeine, i-brown encishisiwe BR, i-phthalocyanine B, i-phthalocyanine Bx, i-monosodium glutamate neminye imikhiqizo.
Inomphumela okhanyayo ekupholiseni kwamakhemikhali ensimbi nensimbi engagqwali, futhi isetshenziswa njenge-corrosion inhibitor ekuqoqweni kwensimbi, kanye nasekulungiseleleni isixazululo se-palladium activation.
Embonini, iphinde isetshenziswe njengempahla eluhlaza yokukhiqiza i-urea formaldehyde resin, i-polyurethane ne-Melamine resin. Lapho i-ureaishisiswe ibe ngu-200 ℃, ikhiqiza i-melamine eqinile (okungukuthi i-cyanuric acid). Okuphuma kokuphuma ku-Cyanuric acid trichloroisocyanuric acid, sodium dichloroisocyanate, tri (2-hydroxyethyl) isocyanurate, tri (Allyl group) isocyanurate, tri (3,5-di-tert-butyl-4-hydroxybenzyl) isocyanate, tri Glycidol ether ye-isocyanic acid , kanye ne-melamine complex ye-cyanuric acid inezicelo eziningi ezibalulekile. Amabili okuqala ama-disinfectants amasha asezingeni eliphezulu kanye nama-bleach, anenani eliphelele lokukhiqiza amathani angaphezu kuka-80000 we-trichloroisocyanuric acid emhlabeni jikelele.
I-ejenti ekhethiwe yokunciphisa i-denitrification yegesi ekhishwayo evuthayo, kanye ne-urea yezimoto, ehlanganisa u-32.5% we-high-purity urea kanye nama-67.5% amanzi akhishwe.
I-Selective Catalytic Reduction (SCR) exhaust post-treatment ubuchwepheshe obudala ngokukhetha ukuncishiswa kwe-nitrogen oxides (NOx) kugesi yokukhipha izimoto ngokusabela kwe-pyrolysis ye-ammonia ekhiqizwa i-urea ekushiseni okuvuthayo. Kuwubuchwepheshe obuyinhloko nobujwayelekile bokunciphisa izinto eziyingozi njenge-NOx kumagesi akhipha amandla avuthayo njengama-boilers nezinjini zikadizili. Uhlelo lwe-SCR luwuhlelo oludingekayo ukuze kuhlangatshezwane nemithetho nemithetho eqinile yokukhipha umoya we-Hyundai Motor Company, njengemithethonqubo ye-Euro IV/Euro V/Euro VI (kazwelonke IV/kazwelonke V/kazwelonke VI).I-urea yezimotoibizwa nge-AdBlue eYurophu kanye ne-DEF e-United States.
Izinto zokusetshenziswa zamapulasitiki akhethekile, ikakhulukazi i-Urea-formaldehyde, ezinye izinto zerabha zokusetshenziswa, umanyolo kanye nezithako zokudla, esikhundleni sikasawoti we-antifreeze ohlakazeke emgwaqweni (inzuzo ukuthi ayigqwali insimbi), ithuthukisa iphunga likagwayi, inikeze i-Pretzel yezimboni ibe nsundu. , i-shampoo ethile, izithako zokuhlanza, izithako zephakheji yesiqandisi sosizo lokuqala (ngoba i-urea ihlangana namanzi ukuze imunce ukushisa), i-urea yezimoto Injini yedizili yokwelapha, injini Igesi engcolile evela ezitshalweni zamandla ashisayo inganciphisa ikakhulukazi i-nitrogen oxide, ukwakheka komgqugquzeli wemvula (usawoti oyinkimbinkimbi), esetshenziselwa ukuhlukanisa upharafini (ngoba i-urea ingakwazi ukwakha i-Inclusion compound), izinto eziphikisayo, ukwakheka kukaphethiloli wenjini yemvelo, ukwakheka imikhiqizo yokucwenga izinyo, umanyolo wamakhemikhali, ama-agent abalulekile asizayo wokudaya nokuphrinta.
