viscosity
Kev txhais lus: Cov khoom ntim ntim ntawm cov kua, quasi-kua, lossis quasi- cov khoom muaj zog uas tiv thaiv ntws; tshwj xeeb, kev sib txhuam sab hauv lossis sab hauv tsis kam ntws tawm ntawm cov molecules thaum cov khoom raug rau sab nraud quab yuam. Feem ntau, viscosity yog ncaj qha proportional rau hardness.
Hardness
Hardness txhais tau hais tias yog cov khoom muaj peev xwm los tiv thaiv hauv zos los ntawm ib qho khoom nyuaj. Silicone roj hmab muaj qhov nyuaj ntawm ntug dej hiav txwv ntawm 10 txog 80, muab cov neeg tsim qauv muaj kev ywj pheej los xaiv qhov nyuaj tshwj xeeb uas yuav tsum tau ua kom ua tiav ib qho haujlwm tshwj xeeb. Los ntawm kev sib xyaw polymer hauv paus, muab tub lim, thiab cov khoom ntxiv hauv qhov sib txawv, qhov dav ntawm qhov nruab nrab hardness qhov tseem ceeb tuaj yeem ua tiav.
Tensile zog
Lub zog tensile yog hais txog lub zog ntawm ib cheeb tsam uas yuav tsum tau ua rau cov qauv ntawm cov khoom siv roj hmab kom tawg. Lub zog tensile ntau rau cov cua sov-vulcanized khoom silicone roj hmab nyob ntawm 4.0 thiab 12.5 MPa. Fluorosilicone roj hmab nthuav tawm lub zog tensile ntau ntawm 8.7 txog 12.1 MPa, thaum cov kua roj hmab silicone muaj li ntawm 3.6 txog 11.0 MPa.
Tear Strength
Lub zog tsim kua muag yog qhov muaj zog tiv thaiv tawm tsam kev nthuav tawm ntawm kev txiav los yog thais thaum quab yuam siv rau cov qauv kos duab. Txawm tias thaum txiav thiab raug kev nyuaj siab heev, tshav kub-vulcanized silicone roj hmab tseem tiv taus kua muag. Lub zog tsim kua muag ntau rau cov cua sov-vulcanized silicone roj hmab poob ntawm 9 txog 55 kN / m.
Elongation
Feem ntau xa mus rau "qhov kawg elongation thaum so," qhov kev ntsuas no sawv cev rau qhov feem pua nce hauv qhov ntev txheeb ze rau qhov ntev ntawm qhov qub tam sim no tus qauv tawg. Qhov dav dav dav dav rau cov cua sov-vulcanized silicone roj hmab yog nyob nruab nrab ntawm 90% thiab 1120%. Fluorosilicon roj hmab feem ntau pom muaj qhov ntev ntawm 159% txog 699%.
