Kuyini i-4,4'-Azobis(4-cyano-1-pentanol) CAS 4693-47-4?

I-4,4'-Azobis (i-4-cyanovaleric acid) iyisiqinisi esimhlophe kuya kokumhlophe uma kushisa ekamelweni kanye nengcindezi. Ine-asidi enkulu kanye nokuqina kwamakhemikhali okubi. Ayincibiliki kahle emanzini kodwa incibilika ezinyibilikisini ezidakayo. . I-4,4'-azobis (i-4-cyanovaleric acid) iyisiqalisi se-polymer esizwela ukukhanya okunamandla futhi ingasetshenziswa ekukhiqizweni kwe-polyvinyl chloride, i-polyacrylonitrile, Ukukhiqizwa kanye nokulungiswa kwama-polymer afana ne-vinyl alcohol kanye nemicu yokwenziwa ye-optical.

Isicelo

1. Ukusetshenziswa ekuphenduleni kwe-polymerization

I-4,4'-azobis (4-cyanopentanol) iyinhlanganisela ye-azo engasetshenziswa njengesiqalisi sokusabela kwe-polymerization. Enkambisweni ye-polymerization yama-free radical, ingabola ukuze ikhiqize ama-free radical ukuze iqalise i-monomer polymerization. Isibonelo, ekusabeleni kwe-polymerization kwama-vinyl monomers njenge-acrylates nama-styrenes, ingalawula ngempumelelo ukuqala kanye nesilinganiso sokusabela kwe-polymerization. Ama-free radicals akhiqizwa ukubola kwawo angaqala ukuvulwa kwezibopho eziphindwe kabili kuma-molecule e-monomer, bese exhuma komunye nomunye ukuze akhe amaketanga e-polymer.

Lo mqalisi unezinzuzo ezithile, njengokuhlinzeka ngesilinganiso sokukhiqiza ama-free radical esizinzile ngaphansi kwezimo zokushisa ezifanele, ukuze ukusabela kwe-polymerization kuqhubeke kahle, okusiza ekwakhiweni kwama-polymers anokusatshalaliswa kwesisindo sama-molecule okuncane.

2. Indima ekulungiseleleni izinto zokufaka igwebu

Ingasetshenziswa futhi ekulungiseleleni izinto zokufaka amagwebu. Ekulungiseleleni izinto zokufaka amagwebu njenge-polyurethane, i-4,4'-azobis (4-cyanopentanol) ingabamba iqhaza ekuphenduleni ukukhiqiza igesi, kanti ama-free radicals namanye amaqembu asebenzayo akhiqizwa ukubola kwawo nawo anegalelo ekuhlanganiseni nasekuphiliseni ama-polymer matrices njenge-polyurethane. Lo mphumela ophindwe kabili uvumela izinto zokufaka amagwebu ukuthi zakhe isakhiwo se-pore esifanayo, futhi usayizi nokusatshalaliswa kwama-pores kungalawulwa ngokulungisa izimo ezifana nomthamo wazo, ngaleyo ndlela kuthuthukiswe izakhiwo zomzimba zezinto zokufaka amagwebu, njengokunciphisa ubuningi bezinto, ukuthuthukisa ukuqina kwezinto kanye nezakhiwo zokufaka amagwebu, njll.
