Urea e ka sebelisoa ka bongata e le lisebelisoa tse tala bakeng sa tlhahiso ea melamine, urea formaldehyde resin, hydrazine hydrate, tetracycline, Phenobarbital, caffeine, e fokotsehile sootho BR, phthalocyanine B, phthalocyanine Bx, monosodium glutamate le lihlahisoa tse ling.

E na le phello e khanyang ho polishing ea lik'hemik'hale tsa tšepe le tšepe e sa hloekang, 'me e sebelisoa e le "corrosion inhibitor" ho pickling ea tšepe, hammoho le ho lokisetsa tharollo ea ts'ebetso ea palladium.
Ka indasteri, e boetse e sebelisoa e le thepa e tala bakeng sa ho etsa urea formaldehyde resin, polyurethane le melamine resin.Ha theureae futhumala ho fihla ho 200 ℃, e hlahisa melamine e tiileng (e leng cyanuric acid).Lintho tse tsoang ho 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 ea isocyanic acid. , le melamine complex ea cyanuric acid e na le lisebelisoa tse ngata tsa bohlokoa.Tse peli tsa pele ke li-disinfectants tse ncha tse phahameng le li-bleach, tse nang le kakaretso ea tlhahiso ea lithane tse fetang 80000 tsa trichloroisocyanuric acid lefatšeng ka bophara.
Sekhechana se ikhethileng bakeng sa ho hlakisoa ha khase e tukang e tukang, hammoho le urea ea likoloi, e nang le 32.5% ea urea e hloekileng le 67.5% ea metsi a deionized.
Selective Catalytic Reduction (SCR) exhaust post-therapy ke theknoloji e khethollang ho fokotseha ha nitrogen oxides (NOx) ka khase ea motlakase ea likoloi ka tsela ea pyrolysis ea ammonia e hlahisoang ke urea nakong ea mollo oa mollo.Ke theknoloji ea bohlokoa le e tloaelehileng ea ho fokotsa lintho tse kotsi tse kang NOx likhase tse tukang tse kang li-boilers le li-diesel.Sistimi ea SCR ke sistimi e hlokahalang ho kopana le melao le melaoana e thata ea ho tsoa ha Hyundai Motor Company, joalo ka melaoana ea Euro IV/Euro V/Euro VI (ea naha IV/national V/ national VI).Urea ea likoloie bitsoa AdBlue Europe le DEF United States.

Lisebelisoa tse tala tsa polasetiki e khethehileng, haholo-holo Urea-formaldehyde, lisebelisoa tse ling tsa rabara, manyolo le lisebelisoa tsa fepa, ho fetola letsoai la antifreeze le hasane seterateng (molemo ke hore ha e senya tšepe), e matlafatsa monko oa lisakerete, e fana ka Pretzel ea indasteri e sootho. , shampoo e 'ngoe, lisebelisoa tsa sesepa, metsoako ea sehatsetsing sa thuso ea pele (hobane urea e arabela ka metsi ho monya mocheso), mochine oa diesel oa urea, mochine oa diesel o hloekisang, enjene. letsoai), e sebelisetsoang ho arola parafine (hobane urea e ka theha motsoako oa Inclusion), lisebelisoa tsa refractory, sebopeho sa mafura a enjene ea tikoloho, sebopeho sa lihlahisoa tse soeufatsang leino, menontsha ea lik'hemik'hale, lisebelisoa tsa bohlokoa tse thusang ho daea le ho hatisa.
