I-Urea ingasetyenziswa ngobuninzi njengento ekrwada yokuveliswa kwe-melamine, i-urea formaldehyde resin, i-hydrazine hydrate, i-tetracycline, i-Phenobarbital, i-caffeine, i-brown eyancipha i-BR, i-phthalocyanine B, i-phthalocyanine Bx, i-monosodium glutamate kunye nezinye iimveliso.

Inomphumela oqaqambileyo kwi-chemical polishing yensimbi kunye nensimbi engenasici, kwaye isetyenziswe njenge-corrosion inhibitor kwi-pickling yensimbi, kunye nokulungiselela isisombululo se-palladium activation.
Kwimizi-mveliso, ikwasetyenziswa njengesixhobo sokuvelisa i-urea formaldehyde resin, i-polyurethane kunye ne-Melamine resin.Xa iureaifudunyezwe ukuya kuma 200 ℃, ivelisa imelamine eqinileyo (okt cyanuric acid).Izinto eziphuma kwi-Cyanuric acid trichloroisocyanuric acid, sodium dichloroisocyanate, tri (2-hydroxyethyl) isocyanurate, tri (Allyl iqela) isocyanurate, tri (3,5-di-tert-butyl-4-hydroxybenzyl) isocyanate, tri Glycidol ether ye isocyanic acid. , kunye ne-melamine complex ye-cyanuric acid inezicelo ezininzi ezibalulekileyo.Ezokuqala zimbini zizibulala-ntsholongwane ezikwisiphelo esiphezulu kunye neeblitshi, ezinomthamo wemveliso ongaphezulu kwe-80000 yeetoni ze-trichloroisocyanuric acid kwihlabathi jikelele.
I-arhente yokunciphisa i-denitrification yokukhupha igesi yokutsha, kunye ne-automotive urea, equka i-32.5% ye-high-purity urea kunye ne-67.5% yamanzi adibeneyo.
I-Selective Catalytic Reduction (SCR) yokukhupha i-post-treatment ye-teknoloji ekhethwa ngokukhethekileyo ukunciphisa i-nitrogen oxides (NOx) kwi-automotive exhaust gas ngokusebenzisa i-pyrolysis reaction ye-ammonia eyenziwa yi-urea kwi-exhaust yokutsha.Ithekhnoloji ephambili kunye neyona nto iphambili ekunciphiseni izinto ezinobungozi ezifana ne-NOx ekutshatyalalisweni kweegesi ezifana neebhoyili kunye neenjini zedizili.Inkqubo ye-SCR yinkqubo efunekayo ukuhlangabezana nemithetho engqongqo yokukhutshwa kwe-Hyundai Motor Company kunye nemimiselo, njenge-Euro IV / Euro V / Euro VI (yesizwe IV / yesizwe V / yesizwe VI) imimiselo.Urea yeemotoibizwa ngokuba yiAdBlue eYurophu kunye neDEF eUnited States.

izinto ekrwada iiplastiki ezikhethekileyo, ingakumbi Urea-formaldehyde, ezinye izinto irabha ekrwada, isichumiso kunye nezithako feed, endaweni ityuwa antifreeze saa esitratweni (inzuzo kukuba ayidleki intsimbi), ukuqinisa ivumba umdiza, ukunika ishishini Pretzel brown. , ezinye ishampu, izithako zokucoca, izithako zephakheji yoncedo lokuqala lwefriji (kuba i-urea isabela ngamanzi ukuze ifunxe ubushushu), i-automotive urea treatment injini ye-diesel, injini Inkunkuma yegesi evela kwizityalo zamandla ashushu inokunciphisa ngokukodwa i-nitrogen oxide, ukubunjwa komgqugquzeli wemvula (i-complex) ityuwa), esetyenziselwa ukwahlula iparafini (kuba i-urea inokwenza i-Inclusion compound), izinto eziphikisayo, ukubunjwa kwe-fuel injini yokusingqongileyo, ukubunjwa kweemveliso ezimhlophe zezinyo, izichumisi zekhemikhali, ii-agent ezincedisayo ezibalulekileyo zokudaya kunye nokuprinta.
