Rabara ea silicone ke e 'ngoe ea lihlahisoa tsa bohlokoa ka ho fetisisa tsa silicone.
Lisebelisoa tse tala bakeng sa ho lokisa rabara ea silicone hangata li entsoe ka linear polysiloxane [rabara e tala ea silicone, e khutsufalitsoeng e le rabara e tala ea silicone], li-fillers tse matlafatsang, li-crosslinking agents, li-catalysts, li-additives tse fetotsoeng, joalo-joalo Lisebelisoa tsohle tse tala li ka etsoa ka rabara e kopantsoeng ka ho kopanya (kapa ho kopanya). Tlas'a maemo a itseng, ha rabara e tsoakiloeng e fapoha-e hokahane 'me e hlephisoa, e ka fetoha ho tloha boemong ba mokelikeli ba viscous ho ea boemong bo rekeresehang haholo - ba vulcanizate.
Sebopeho sa lik'hemik'hale sa rabara e tala se tšoana le sa oli ea silicone, 'me mokhoa oa eona o akaretsang ke o latelang:
Ka mokhoa o akaretsang, R 'e emela sehlopha sa alkyl kapa hydroxyl,' me R hangata ke sehlopha sa methyl, empa lihlopha tse ling tse kang ethyl, vinyl, phenyl, trifluoropropyl, joalo-joalo li ka boela tsa hlahisoa ho ntlafatsa le ho ntlafatsa thepa e itseng. Mohlala, ho nkela karolo ea lihlopha tsa methyl sebaka ka lihlopha tsa phenyl ho ka ntlafatsa ho feto-fetoha ha maemo le ho hanyetsa mahlaseli a rabara ea silicone ka mocheso o tlase. Ho hlahisa vinyl e nyane ho ka ntlafatsa ts'ebetso ea vulcanization le sete ea compression ea rabara ea silicone.
Ho ba teng ha lihlopha tsa trifluoropropyl ho ka etsa hore rabara ea silicone e be le khanyetso e ntle ea oli. Rabara ea Silicone e nang le lihlopha tsa cyano, joalo ka rabara ea fluorosilicone, e khona ho thibela{1}}litlhapi tse se nang polar. Ka mor'a ho hlahisa palo e itseng ea lihlopha tsa phenylene ka har'a ketane e kholo ea siloxane ea rabara ea silicone, matla a mochine a ka eketsoa ho tloha 110MPa ho ea ho 170-180MPa, 'me ho hanyetsa mocheso ho boetse ho ntlafatsoa.
Ka hona, ho itšetlehile ka lihlopha tse fapaneng tsa tlhaho tse khomaretsoeng liathomong tsa silicon, rabara ea silicone e ka aroloa ka mefuta e mengata e kang dimethyl silicone rabara, methyl vinyl silicone rabara, rabara ea methyl phenyl silicone, rabara ea fluorosilicone, rabara ea silicone ea nitrile, rabara ea silicone ea ethyl le rabara ea silicone ea phenylene.
