Mchitidwe wa vulcanization wa peroxide wokwera-kutentha kwa mphira wa silikoni umachitika molingana ndi makina a free radical reaction mechanism. Kukatenthedwa, ma organic peroxides amawola kupanga ma free radicals, omwe pambuyo pake amalumikizana ndi magulu a organic mu mamolekyu a polysiloxane monga magulu a methyl ndi ethyl kupanga -mamolekyulu aulere. Pamene -mamolekyulu omasuka a ma radicals amalumikizana, kuwoloka-kulumikizana kumachitika.
Pali ma peroxides asanu ndi limodzi omwe amagwiritsidwa ntchito kwambiri mu raba ya silikoni yotentha-yotentha kwambiri. Mikhalidwe ya vulcanization ndi kukula kwake kwa ma peroxides osiyanasiyana sikufanana.
Ogwiritsa ntchito amatha kusankha mankhwala oyenera malinga ndi zosowa zawo. Mwachitsanzo, kutentha kochepera-kuwola kwa peroxides monga di peroxide (2, 4-dichlorobenzene) kungapereke chiwopsezo chofulumira kwambiri, ndipo mphamvu ya nthunzi ya zinthu zake zowola imakhala yochepa kwambiri, choncho palibe kukakamiza kwina komwe kumafunika kuti tipewe kupanga ma pores. Choncho, pawiri izi zambiri ntchito otentha mpweya vulcanization extrusion ndi akamaumba njira. Komabe, chifukwa cha liwiro lofulumira la vulcanization, kuwotcha kumakhala kotheka poponya zinthu zoonda kapena kusamutsa nkhungu. Zikatero, peroxide yokhala ndi liwiro locheperako, monga benzoyl peroxide, ndiyoyenera.
Komabe, chigawo ichi chidzatulutsa mpweya panthawi ya vulcanization, kotero sichikhoza kutenthedwa ndi mpweya wotentha. M'malo mwake, vulcanization mosalekeza ndi nthunzi imagwiritsidwa ntchito. Choyipa chinanso chazomwe zili pamwambapa-zomwe zatchulidwazi zotsika-zowononga kutentha ndizakuti poponya zinthu zocheperako, zowola zake zimakhala ndi vuto lalikulu pakutentha kwazinthuzo.
Ngakhale kuti zinthu zotenthetsera kwambiri-zotentha monga diisopropylbenzene peroxide ndi di-tert-butyl peroxide ndizoyenera mphira wa methyl vinyl waiwisi wokhawokha, ndizomwe zimawononga kwambiri zinthu zonenepa ndipo zitha kugwiritsidwanso ntchito mumdima wakuda- wokhala ndi mphira wakuda wa kaboni{3}
