Indima ye-urea kwintsimi yezoshishino

Iindaba

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-agent ekhethiweyo yokunciphisa i-denitrification yegesi yokutshisa igesi, kunye ne-automotive urea, equka i-32.5% ye-high-purity urea kunye ne-67.5% yamanzi e-deionized.
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. , ishampu ethile, izithako zokucoca, izithako zephakheji yoncedo lokuqala lwefriji (kuba i-urea isabelana namanzi ukuze ifunxe ubushushu), i-automotive urea. unyango injini yedizili, injini Inkunkuma igesi evela kwizityalo amandla thermal inganciphisa ngokukodwa nitrogen oxide, ukwakheka umxhasi imvula (ityuwa enzima), esetyenziselwa ukwahlula iparafini (kuba urea ungenza Inclusion compound), izinto eziphikisayo, ukubunjwa kwe-injini yendalo esingqongileyo iimveliso zokuthambisa izinyo, izichumisi zeekhemikhali, ii-agent ezincedisayo ezibalulekileyo zokudaya kunye nokushicilela.
