Urea irashobora gukoreshwa mubwinshi nkibikoresho fatizo kugirango habeho umusaruro wa melamine, urea formaldehyde resin, hydrazine hydrate, tetracycline, Phenobarbital, cafeyine, kugabanuka kwijimye BR, phthalocyanine B, phthalocyanine Bx, monosodium glutamate nibindi bicuruzwa.

Ifite ingaruka nziza kumashanyarazi yicyuma nicyuma, kandi ikoreshwa nkigikoresho cyo kwangirika kwangiza ibyuma, ndetse no gutegura igisubizo cya palladium.
Mu nganda, ikoreshwa kandi nkibikoresho fatizo byo gukora urea formaldehyde resin, polyurethane na Melamine resin.Iyoureaashyutswe kugeza 200 ℃, itanga melamine ikomeye (ni aside aside).Ibikomoka kuri acide ya Cyanuric trichloroisocyanuric, sodium dichloroisocyanate, tri (2-hydroxyethyl) isocyanurate, tri (itsinda rya Allyl) isocyanurate, tri (3,5-di-tert-butyl-4-hydroxybenzyl) isocyanate, tri Glycidol ether. , na melamine igizwe na acide cyanuric ifite ibintu byinshi byingenzi.Babiri ba mbere ni imiti mishya yo mu rwego rwo hejuru kandi yangiza, ifite ubushobozi bwo gutanga toni zirenga 80000 za acide trichloroisocyanuric ku isi.
Kugabanya imiti igabanya ubukana bwa gaze yaka umuriro, hamwe na urea yimodoka, igizwe na 32.5% urea-isukuye cyane hamwe n’amazi 67.5%.
Guhitamo Catalitike yo Kugabanya (SCR) nyuma yo kuvurwa ni tekinoroji itera guhitamo kugabanya kugabanuka kwa okiside ya azote (NOx) muri gaze ya gaze ya moteri ikoresheje pyrolysis reaction ya ammonia iterwa na urea mumuriro ugurumana.Nubuhanga bwingenzi kandi bwibanze bwo kugabanya ibintu byangiza nka NOx mumyuka yuka yaka nka boiler na moteri ya mazutu.Sisitemu ya SCR ni gahunda ikenewe kugira ngo hubahirizwe amategeko n'amabwiriza akomeye ya sosiyete ya Moteri ya Hyundai, nka Euro IV / Euro V / Euro VI (igihugu cya IV / igihugu V / igihugu VI).Imodoka ya ureayitwa AdBlue mu Burayi na DEF muri Amerika.

Ibikoresho bibisi bya plastiki zidasanzwe, cyane cyane Urea-formaldehyde, ibikoresho bimwe na bimwe bya reberi, ifumbire n’ibikoresho byo kugaburira, gusimbuza umunyu wa antifreeze ukwirakwijwe mu muhanda (ibyiza ni uko bitangirika ibyuma), byongera impumuro y’itabi, biha inganda Pretzel inganda , shampoo zimwe na zimwe, ibikoresho byogeramo ibikoresho, ibikoresho byububiko bwambere bwo gukonjesha (kubera ko urea ifata amazi kugirango ikuremo ubushyuhe), moteri ya urea itwara moteri ya moteri, moteri ya gaze imyanda iva mumashanyarazi yumuriro irashobora kugabanya cyane cyane okiside ya azote, igizwe niterambere ryimvura (complexe umunyu), ikoreshwa mugutandukanya paraffine (kubera ko urea ishobora gukora Include compound), ibikoresho bivunika, ibice bya lisansi y’ibidukikije, ibigize ibikoresho byera amenyo, ifumbire mvaruganda, ibikoresho byingenzi bifasha gusiga no gucapa.
