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 ukuvuga aside cyanuric). 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 byinshi byingenzi Porogaramu. Babiri ba mbere ni udushya twinshi two mu rwego rwo hejuru hamwe na bleach, hamwe n’umusaruro wose wa 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, ibikoresho byogeramo ibikoresho, ibikoresho byubufasha bwambere bwo gukonjesha (kuko urea ifata amazi kugirango ikure ubushyuhe), moteri ya urea itwara moteri, moteri Imyanda iva mumashanyarazi yumuriro irashobora kugabanya cyane cyane okiside ya azote, igizwe na porotokoro yimvura (umunyu utoroshye), ikoreshwa mugutandukanya paraffine (kubera ko urea ishobora gukora compound Include), ibikoresho bivunika, ibice bya lisansi y’ibidukikije, ibigize ibikoresho byera amenyo, ifumbire mvaruganda, ingirakamaro zingirakamaro zo gusiga no gucapa.
