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

4,4'-Azobis (4-cyanovaleric acid) ndi yoyera mpaka yoyera yolimba pa kutentha ndi kupanikizika. Ili ndi acidity yayikulu komanso kusakhazikika kwamankhwala. Simasungunuka bwino m'madzi koma amasungunuka mu zosungunulira za mowa. . 4,4'-azobis(4-cyanovaleric acid) ndi polima initiator amene tcheru kuwala kwamphamvu ndipo angagwiritsidwe ntchito popanga polyvinyl kolorayidi, polyacrylonitrile, Kupanga ndi kukonza ma polima monga vinilu mowa ndi kupanga ulusi kuwala.

Kugwiritsa ntchito

1. Kugwiritsa ntchito polima

4,4'-azobis(4-cyanopentanol) ndi azo pawiri kuti angagwiritsidwe ntchito ngati woyambitsa kwa polymerization zimachitikira. M'kati mwa ma polymerization aulere, amatha kuwola kuti apange ma free radicals kuti ayambitse polymerization ya monomer. Mwachitsanzo, mu polymerization anachita wa vinilu monomers monga acrylates ndi styrenes, akhoza bwino kulamulira chiyambi ndi mlingo wa polymerization anachita. Ma radicals aulere opangidwa ndi kuwonongeka kwake amatha kuyambitsa kutsegulidwa kwa zomangira ziwiri mu mamolekyu a monomer, kenako ndikulumikizana wina ndi mnzake kuti apange maunyolo a polima.

Woyambitsa uyu ali ndi zabwino zina, monga kupereka mokhazikika m'badwo wokhazikika waulere pansi pamikhalidwe yoyenera kutentha, kuti polymerization ipitirire bwino, yomwe imathandizira kaphatikizidwe ka ma polima ndi kugawa kwapang'onopang'ono kwa maselo.

2. Ntchito yokonza zinthu zotulutsa thovu

Itha kugwiritsidwanso ntchito pokonzekera zinthu zotulutsa thovu. Pokonzekera zinthu zotulutsa thovu monga polyurethane, 4,4'-azobis(4-cyanopentanol) amatha kutenga nawo mbali pakuchitapo kanthu kuti apange mpweya, ndipo ma free radicals ndi magulu ena ogwira ntchito omwe amapangidwa ndi kuwonongeka kwake amathandizanso kuphatikizika ndi kuchiritsa matrices a polima monga polyurethane. Izi wapawiri zotsatira zimathandiza thovu zinthu kupanga yunifolomu pore dongosolo, ndi kukula ndi kugawa pores akhoza lizilamuliridwa ndi kusintha zinthu monga mlingo wawo, potero kuwongolera thupi katundu thovu zakuthupi, monga kuchepetsa kachulukidwe zakuthupi, kuwongolera zinthu elasticity ndi cushioning katundu, etc.
