Elastomer O-Ring Silicon Khoom nta

Qhov tseem ceeb tshaj plaws yam ntxwv ntawm silicone yog nws elasticity. High elasticity originates los ntawm molecular motion thiab yog kiag li tshwm sim los ntawm conformational hloov nyob rau hauv silicon molecules. Nws tuaj yeem rov qab tau tam sim ntawd tom qab tshem tawm cov quab yuam sab nraud, uas yog hu ua zoo tagnrho elastomers.

Kev sib cuam tshuam ntawm silicon molecules tuaj yeem cuam tshuam kev txav ntawm cov ntu molecular, qhia txog viscosity lossis viscosity. Cov khoom ntawm silicone roj hmab yog ob qho tib si elastic thiab viscous. Cov yam tseem ceeb uas cuam tshuam rau elasticity yog pom nyob rau hauv cov nqe lus ntawm qhov loj, lub sij hawm ua hauj lwm, kub, thiab lwm yam. Thaum cov kev sib cuam tshuam ntawm silicone molecules nce thiab cov tsis tu ncua ntawm molecular chains yog siab, lub tensile lub zog yuav tau yooj yim txhim kho, qhia siab elasticity. Lub elasticity ntawm silicone muaj feem xyuam rau crosslinking ceev. Raws li qhov ceev nce, qhov elasticity ntawm vulcanizate nce, thiab qhov siab tshaj plaws tus nqi tshwm. Txoj hauv kev ncaj ncees tshaj plaws thiab ua tau zoo los ua kom elasticity yog kom tsim nyog nce qib ntawm fluidization thiab nce cov ntsiab lus roj hmab.

Lub elongation ntawm tawg (elongation) muaj feem xyuam rau lub zog tensile. Tsuas yog los ntawm kev muaj zog tensile siab thiab xyuas kom meej tias nws tsis puas thaum lub sij hawm deformation tuaj yeem ua tiav qhov siab elongation. Feem ntau, nrog rau qhov nce ntawm qhov tensile kev nyuaj siab thiab hardness, lub pob txha elongation txo, lub elasticity yog loj, mus tas li deformation yog me me, thiab cov pob txha elongation yog loj. Cov nplaum sib txawv muaj qhov sib txawv ntawm cov pob txha elongation.
