Urea waxaa loo isticmaali karaa tiro badan sida alaabta ceeriin ee soo saarista melamine, urea formaldehyde resin, hydrazine hydrate, tetracycline, Phenobarbital, caffeine, brown BR, phthalocyanine B, phthalocyanine Bx, monosodium glutamate iyo alaabooyin kale.

Waxay leedahay saameyn ifaya oo ku saabsan nadiifinta kiimikaad ee birta iyo birta aan fiicnayn, waxaana loo isticmaalaa sidii daxal-xakameeyaha soo saarista birta, iyo sidoo kale diyaarinta xalka firfircoonida palladium.
Warshadaha, waxa kale oo loo isticmaalaa sidii alaabta ceeriin ee soo saarista urea formaldehyde resin, polyurethane iyo resin Melamine.MarkaHOLwaxa la kululeeyaa ilaa 200 ℃, waxa ay dhalisaa melamine adag (ie cyanuric acid).Qaybaha kala duwan ee 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 of isocyanate. , iyo melamine complex of cyanuric acid waxay leeyihiin codsiyo badan oo muhiim ah.Labada hore waa jeermis-dileyaal heer-sare ah oo cusub iyo bleaches, oo leh wadarta wax-soo-saarka in ka badan 80000 oo tan oo trichloroisocyanuric acid adduunka oo dhan ah.
Wakiilka yaraynta xulashada ee denitrification ee gaasta qiiqa gubta, iyo sidoo kale urea baabuurta, oo ka kooban 32.5% HOL-nadiifinta sare iyo 67.5% biyaha deionized.
Hoos u dhigista Katalytic Selective (SCR) daawaynta ka dib waa tignoolajiyad si door ah u kataliya dhimista oxides nitrogen (NOx) ee gaasta qiiqa baabuurta iyada oo loo marayo falcelinta pyrolysis ee ammonia ee ay ka dhaliso HOL ee qiiqa gubanaya.Waa tignoolajiyada muhiimka ah iyo kuwa caadiga ah si loo yareeyo walxaha waxyeelada leh sida NOx ee gaaska qiiqa gubanaya sida kuleyliyaha iyo matoorada naaftada.Nidaamka SCR waa nidaam lagama maarmaan ah si loo buuxiyo sharciyada adag ee shirkadda Hyundai Motor Company, sida Euro IV/Euro V/Euro VI (qaranka IV/qaranka V/qaranka VI).Uriyo baabuurtawaxaa loogu yeeraa AdBlue gudaha Yurub iyo DEF gudaha Mareykanka.

Walxaha ceeriin ee caagadaha gaarka ah, gaar ahaan Urea-formaldehyde, qaar ka mid ah alaabta ceeriin caag, bacriminta iyo maaddooyinka quudinta, beddelaya milix-freeze ku kala firdhiyey waddada (faa'iidada waa in aanay daxaloobay biraha), kor u urta sigaarka, siinta warshadaha Pretzel brown. , shaambo qaar ka mid ah, maaddooyinka saabuunta, maaddooyinka xirmada qaboojiyaha gargaarka degdegga ah (maxaa yeelay HOL waxay ka falcelisaa biyaha si ay u nuugaan kulaylka), mashiinka naaftada daweynta urea baabuurta, mishiinka gaaska qashinka ah ee dhirta tamarta kulaylka ayaa si gaar ah u yareeyn kara nitrogen oxide, ka kooban dhiirigeliyaha roobka (isku-dhafan cusbo), oo loo isticmaalo in lagu kala saaro paraffin (sababtoo ah kaadimareenku waxay samayn kartaa iskudarka Inclusion), walxaha refractory, ka kooban shidaalka engine deegaanka, ka kooban alaabta caddeeyo ilig, Bacriminta kiimikada, wakiilada muhiimka ah ee kaabayaal ah dheehidda iyo daabacaadda.
