Intengo encishisiwe ye-China Factory Supply Dbu CAS 6674-22-2 Dbu enentengo engcono kakhulu
Ngobuchwepheshe obuthuthukisiwe kanye nezindawo, ukulawulwa okuqinile kwekhwalithi ephezulu, inani elifanele, inkampani enhle kakhulu kanye nokubambisana okuseduze namakhasimende, sizinikele ekunikezeni inani elihle kakhulu kumakhasimende ethu ngentengo ephansi ye-China Factory Supply.I-DbuI-CAS 6674-22-2Dbu ngentengo engcono kakhulu, Siyaziqhenya kakhulu ngokuthandwa kwakho okuhle kakhulu ngamakhasimende ethu ngekhwalithi ehloniphekile yemikhiqizo yethu.
Ngobuchwepheshe obuthuthukisiwe kanye nezindawo, ukulawula okuqinile kwekhwalithi ephezulu, inani elifanele, inkampani evelele kanye nokubambisana okuseduze nabathengi abafisa ukuthenga, besizinikele ekunikezeni inani elihle kakhulu kubathengi bethu, Kuze kube manje izimpahla zethu zithunyelwe empumalanga yeYurophu, eMpumalanga Ephakathi, eNingizimu-mpumalanga, e-Afrika naseNingizimu Melika njll. Manje sesineminyaka engu-13 sinolwazi lokuthengisa nokuthenga izingxenye ze-Isuzu ekhaya nakwamanye amazwe kanye nobunikazi bezinhlelo zokuhlola izingxenye ze-Isuzu ze-elekthronikhi zesimanje. Sihlonipha inhloko yethu eyinhloko yokwethembeka ebhizinisini, ukubeka phambili insizakalo futhi sizokwenza konke okusemandleni ethu ukunikeza amakhasimende ethu izinto ezisezingeni eliphezulu kanye nensizakalo enhle kakhulu.
1,8-diazabicyclo [5.4.0] undec-7-ene, efingqiwe ngokuthiI-DBU, iyi-amidine enesakhiwo se-heterocyclic. Igama layo lesiNgisi yi-1,8-diazabicyclo [5.4.0] undec-7-ene. Iwuketshezi oluphuzi olungenambala noma olukhanyayo ekushiseni kwegumbi futhi lungancibilikiswa ezinyibilikisini ezahlukahlukene eziphilayo ezifana namanzi, i-ethanol, i-acetone, njll. Ngokuvamile igcinwa emazingeni okushisa angaphansi kwama-30 ℃.

I-DBUingasetshenziswa njengesikhuthazi sokukhiqizwa kwe-polyaminomethanol ethyl ester kanye neminye imikhiqizo yamakhemikhali, njengokusabela kwe-ammonia ne-dichloroethane ukukhiqiza i-piperazine lapho ikhona. Iyi-ejenti enhle kakhulu yokuqeda amanzi emzimbeni, i-epoxy resin hardener, i-rust inhibitor, futhi ingakhiwa njenge-advanced corrosion inhibitor. Isetshenziswa kabanzi ekukhiqizweni kwama-antibiotic e-semi synthetic cephalosporin.
Ngokuvamile kupakishwe ku-25kg/isigubhu, futhi kungenziwa ngezifiso.
