Kodi 4,4'-Azobis(4-cyano-1-pentanol) CAS 4693-47-4 ndi chiyani?

4,4'-Azobis (4-cyanovaleric acid) ndi yoyera mpaka yoyera pang'ono kutentha kwa chipinda ndi kupanikizika. Ili ndi asidi wambiri komanso kukhazikika kwa mankhwala koyipa. Siisungunuka bwino m'madzi koma imasungunuka mu zosungunulira za alcohol organic. . 4,4'-azobis (4-cyanovaleric acid) ndi choyambitsa polima chomwe chimakhudzidwa ndi kuwala kwamphamvu ndipo chingagwiritsidwe ntchito popanga polyvinyl chloride, polyacrylonitrile, Kupanga ndi kukonza ma polima monga vinyl alcohol ndi ulusi wopangira kuwala.

Kugwiritsa ntchito

1. Kugwiritsa ntchito pochita zinthu pogwiritsa ntchito polymerization

4,4'-azobis (4-cyanopentanol) ndi mankhwala a azo omwe angagwiritsidwe ntchito ngati choyambitsa ma polymerization reactions. Mu ndondomeko ya free radical polymerization, imatha kuwola kuti ipange ma free radicals kuti iyambe monomer polymerization. Mwachitsanzo, mu polymerization reaction ya vinyl monomers monga acrylates ndi styrenes, imatha kuwongolera bwino kuyambitsa ndi liwiro la polymerization reaction. Free radicals yomwe imapangidwa ndi kuwonongeka kwake imatha kuyambitsa kutseguka kwa ma bond awiri mu mamolekyu a monomer, kenako n'kulumikizana kuti apange ma polymer chains.

Choyambitsa ichi chili ndi ubwino wina, monga kupereka chiŵerengero chokhazikika cha kupanga ma free radical pansi pa kutentha koyenera, kotero kuti polymerization reaction ikhoza kupitirira bwino, zomwe zimathandiza kupanga ma polima okhala ndi kugawa kochepa kwa molekyulu.

2. Udindo pakukonzekera zinthu zotulutsa thovu

Ingagwiritsidwenso ntchito pokonzekera zinthu zopangira thovu. Pokonzekera zinthu zopangira thovu monga polyurethane, 4,4'-azobis (4-cyanopentanol) imatha kutenga nawo mbali popanga mpweya, ndipo ma free radicals ndi magulu ena ogwira ntchito omwe amapangidwa ndi kuwonongeka kwake amathandiziranso kulumikiza ndi kuchiritsa ma polymer matrices monga polyurethane. Izi zimapangitsa kuti zinthu zopangira thovu zipange mawonekedwe ofanana a ma pore, ndipo kukula ndi kufalikira kwa ma pores kumatha kulamulidwa mwa kusintha zinthu monga mlingo wawo, potero kukonza mawonekedwe enieni a zinthu zopangira thovu, monga kuchepetsa kuchuluka kwa zinthuzo, kukonza kusinthasintha kwa zinthuzo ndi mphamvu zotetezera, ndi zina zotero.
