E mafai ona faʻaaogaina le Urea i le tele o meafaitino mo le gaosiga o le melamine, urea formaldehyde resin, hydrazine hydrate, tetracycline, Phenobarbital, caffeine, faʻaitiitia BR brown, phthalocyanine B, phthalocyanine Bx, monosodium glutamate ma isi oloa.
E i ai se aafiaga susulu i luga o kemikolo polesi o le uamea ma le uamea stainless, ma o loo faaaogaina e avea o se inhibitor corrosion i uʻamea pickling, faapea foi i le sauniuniga o le palladium activation solution.
I alamanuia, o loʻo faʻaaogaina foi e avea ma mea mata mo le gaosiga o le urea formaldehyde resin, polyurethane ma le Melamine resin.Ina ua leureae vevela i le 200 ℃, e maua ai le melamine malo (ie cyanuric acid).O mea e maua mai le 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 o le isocyanic acid , ma le melamine complex o le cyanuric acid e tele mea taua.O mea muamua e lua o ni vaila'au fa'ama'i fou fou ma pi'imu, fa'atasi ai ma le aofa'i o le gaosiga e sili atu i le 80000 tone o le trichloroisocyanuric acid i le lalolagi atoa.
Sui fa'aitiitiga filifilia mo le denitrification o kesi fa'avevela afi, fa'apea fo'i le urea ta'avale, e aofia ai le 32.5% maualuga-mama urea ma le 67.5% vai deionized.
Selective Catalytic Reduction (SCR) exhaust post-treatment o se tekonolosi e faʻatupuina le faʻaititia o le nitrogen oxides (NOx) i le kasa faʻamalo taavale e ala i le pyrolysis reaction o ammonia e gaosia e le urea i le afi afi.Ose tekinolosi autu ma fa'atumauina mo le fa'aitiitia o mea fa'aleagaina e pei ole NOx ile kasa fa'avevela e pei ole kasa ma afi tiso.O le faiga o le SCR o se faiga e mana'omia e fa'afetaui ai tulafono ma fa'atonuga a le Kamupani a le Hyundai Motor Company, e pei o le Euro IV/Euro V/Euro VI (national IV/national V/national VI).Urea tau taavaleua ta'ua o le AdBlue i Europa ma le DEF i le Iunaite Setete.
Mea mata o palasitika faʻapitoa, aemaise lava Urea-formaldehyde, nisi mea paʻu mata, fetilaisa ma meaʻai meaʻai, sui masima antifreeze faʻasalalau i luga o le auala (o le lelei e le afaina ai le uamea), faʻaleleia le manogi o sikaleti, tuʻuina atu pisinisi Pretzel enaena. , nisi shampoo, mea fa'amama, mea o le pusa pusaaisa fesoasoani muamua (ona o le urea e tali atu i le vai e faʻafefe ai le vevela), masini faʻamalo ole urea taʻavale, afi ole kasa otaota mai fale eletise vevela e mafai ona faʻaitiitia ai le nitrogen oxide, faʻapipiʻi o le timu faʻalauiloa (lavelave. masima), faʻaaogaina e vavae ese ai paraffin (ona o le urea e mafai ona faʻapipiʻi faʻapipiʻi Faʻapipiʻi), mea faʻafefeteina, tuʻufaʻatasiga o suauʻu afi afi, tuʻufaʻatasiga o oloa paʻepaʻe nifo, vailaʻau vailaʻau, mea taua fesoasoani mo le valiina ma le lolomiina.
