Isicelo

1. Ukusetyenziswa kwiimpendulo ze-polymerization

I-4,4'-azobis (4-cyanopentanol) yi-azo compound enokusetyenziswa njengesiqalo seempendulo ze-polymerization. Kwinkqubo ye-free radical polymerization, inokubola ukuze ivelise ii-free radicals ukuze iqalise i-monomer polymerization. Umzekelo, kwi-polymerization reaction yee-vinyl monomers ezifana nee-acrylates kunye nee-styrenes, inokulawula ngempumelelo ukuqaliswa kunye nesantya se-polymerization reaction. Ii-free radicals eziveliswa kukubola kwayo zinokuqalisa ukuvulwa kweebhondi eziphindwe kabini kwiimolekyuli ze-monomer, zize emva koko ziqhagamshelene ukuze zenze imixokelelwane ye-polymer.

Lo mqalisi unezibonelelo ezithile, ezinje ngokubonelela ngesantya sokuvelisa ii-free radicals ezizinzileyo phantsi kweemeko zobushushu ezifanelekileyo, ukuze impendulo ye-polymerization iqhubeke kakuhle, nto leyo enceda ekuhlanganisweni kwee-polymers ezinokusasazwa kobunzima be-molecular obuncinci.

2. Indima ekulungiseleleni izinto ezikhupha amagwebu

Ingasetyenziselwa nokulungiselela izinto zokufaka igwebu. Ekulungiseleleni izinto zokufaka igwebu ezifana ne-polyurethane, i-4,4'-azobis (4-cyanopentanol) inokuthatha inxaxheba kwimpendulo yokuvelisa igesi, kwaye ii-free radicals kunye namanye amaqela asebenzayo aveliswa kukubola kwayo nawo anegalelo ekudibaniseni nasekuphiliseni ii-polymer matrices ezifana ne-polyurethane. Esi siphumo siphindwe kabini senza ukuba izinto zokufaka igwebu zenze isakhiwo se-pore esifanayo, kwaye ubungakanani kunye nokusasazwa kwee-pores kunokulawulwa ngokulungelelanisa iimeko ezifana nomthamo wazo, ngaloo ndlela kuphuculwe iipropati zomzimba zezinto zokufaka igwebu, ezinje ngokunciphisa uxinano lwezinto, ukuphucula ukuthamba kwezinto kunye neepropati zokunciphisa, njl.
