Cov roj hmab silicone roj hmab yog ib qho ntawm cov khoom lag luam uas tseem ceeb tshaj plaws.
Cov ntaub ntawv raw rau kev npaj silicone roj hmab feem ntau yog tsim ntawm cov roj hmab polysiloxane [thiab lwm yam ntawm cov roj hmab raw tuaj yeem ua rau cov roj hmab raw tuaj yeem los ntawm kev sib xyaw (lossis sib xyaw). Nyob rau hauv qee qhov kev mob, thaum sib xyaw roj hmab yog hla-}}} {{}}} vulcanizate.
Cov qauv tshuaj ntawm cov roj hmab raw zoo ib yam li ntawm cov roj silicone, thiab nws cov mis dav dav yog raws li hauv qab no:
Hauv cov qauv siv dav dav, r 'sawv cev rau ib pawg alkyl lossis hydroxyl, tab sis lwm pab pawg, ua haujlwm tseem ceeb rau kev txhim kho thiab txhim kho qee yam khoom. Piv txwv li, hloov ib feem ntawm cov methyl pawg nrog cov pab pawg phenyyl tuaj yeem txhim kho cov roj hmab hloov thiab hluav taws xob tsis kam ntawm silicone roj hmab ntawm tsawg kub. Qhia me me ntawm Vinyl tuaj yeem txhim kho qhov kev ua yeeb yam vulcanization thiab compression teeb ntawm silicone roj hmab.
Lub xub ntiag ntawm trifluoropropropyl tuaj yeem tso cov roj hmab silicone nrog cov roj ua tsis tau zoo. Cov roj hmab silicone muaj cov pab pawg cyano, xws li cov roj hmab fluorosilicone, roj hmab tsis tuaj yeem tawm tsam tsis- polar kuab tshuaj. Tom qab qhia txog qee pab pawg Phenylene mus rau hauv cov siloxane lub saw hlau tau nce los ntawm 110MPA rau 170-180MPA, thiab cov cua sov kuj tseem muaj kev txhim kho.
Yog li no, nyob ntawm cov pab pawg organic sib xyaw nrog rau silicon atoms, silicone roj hmab, nitrile silicone roj hmab, roj hmab silicone roj hmab thiab roj hmab silicone roj hmab.
