Silicone roba yana daya daga cikin mahimman samfuran silicone.
The raw kayan don shirya silicone roba yawanci hada da linzamin kwamfuta polysiloxane [silicone roba raw roba, raguwa a matsayin silicone raw rubber], ƙarfafa fillers, crosslinking jamiái, catalysts, modified Additives, da dai sauransu Dukan albarkatun kasa za a iya sarrafa a fili roba ta hanyar hadawa (ko blending). A ƙarƙashin wasu sharuɗɗa, lokacin da aka haɗe robar da aka haɗe da vulcanized, yana iya canzawa daga yanayin ruwa mai ɗanɗanowa zuwa yanayi mai ƙarfi sosai - vulcanizate.
Tsarin sinadarai na danyen roba yayi kama da na man silicone, kuma tsarinsa na gaba daya shine kamar haka:
A cikin tsari na gaba ɗaya, R 'yana wakiltar ƙungiyar alkyl ko hydroxyl, kuma R yawanci ƙungiyar methyl ne, amma sauran ƙungiyoyi kamar ethyl, vinyl, phenyl, trifluoropropyl, da sauransu kuma ana iya gabatar da su don haɓakawa da haɓaka wasu kaddarorin. Misali, maye gurbin wani yanki na ƙungiyoyin methyl tare da ƙungiyoyin phenyl na iya haɓaka juriya da juriya na robar silicone a ƙananan yanayin zafi. Gabatar da ƙaramin adadin vinyl zai iya inganta aikin vulcanization da saitin matsi na roba na silicone.
Kasancewar ƙungiyoyin trifluoropropyl na iya ba da roba silicone tare da kyakkyawan juriya mai. Robar silicone mai ɗauke da ƙungiyoyin cyano, kamar roba na fluorosilicone, na iya yin tsayayya marasa ƙarfi. Bayan gabatar da wani adadin phenylene kungiyoyin a cikin siloxane babban sarkar silicone roba, da inji ƙarfi za a iya ƙara daga 110MPa zuwa 170-180MPa, da kuma zafi juriya an inganta.
Saboda haka, dangane da daban-daban kwayoyin kungiyoyin da aka haɗe da silicon atom, silicone roba za a iya classified zuwa da yawa iri kamar dimethyl silicone roba, methyl vinyl silicone roba, methyl phenyl silicone roba, fluorosilicone roba, nitrile silicone roba, ethyl silicone roba da phenylene silicone roba.
