Kev siv tshuab ua tau zoo tshaj thiab kev ua haujlwm kub ntev ntev tau ua qhov tseem ceeb rau ntau lub tsheb luv-hauv-hood kev siv. Nruam sab saud kub tiv thaiv (CUTR) ntawm thermoset EPDM roj hmab txhais tau tias yog qhov kub siab tshaj qhov nruab nrab ntawm cov laus kev ua kom sov thaum lub thermoset compound khaws tsawg kawg 50 feem pua ntawm thawj elongation thiab 80 feem pua tensile thaum so tom qab 1,008 teev ntawm kev laus thaum tshav kub (per Mercedes-Benz Khoom Qhia Tshwj Xeeb ntawm Textile-txhawb ntxiv coolant hoses-DBL 6254).
Nws yog ib txoj haujlwm nyuaj rau ntau ntawm thermoset EPDM cov khoom siv roj hmab cov khoom lag luam kom tau raws li cov kev cai txuas ntxiv ntawm CUTR thiab lwm qhov kev tsim qauv nruj dua rau cov khoom siv hauv lub tsheb, xws li qis-qhov-hood coolant hose, hlau thiab cable, thiab lwm yam.
Hauv daim ntawv no qhov kub ua rau kev laus ntawm vulcanized EPDM tebchaw tau tshawb fawb txog qhov system. EPDM thermal oxidation / degradation mechanism tau npaj siab thiab tham txog. Ntxiv rau, cov teebmeem ntawm EPDM molecular architecture, antioxidants thiab EPDM compound formulations ntawm cov khoom siv ntev thaum tshav kub kub tau tshawb xyuas. Thaum kawg, lub siab tshaj qhov kub thiab txias tiv thaiv EPDM tov tau muaj kev tsim kho zoo rau kev siv lub tshuab ua kom txias txias hose kom muab cov khoom lag luam tsim tau zoo ua ntej thiab tom qab lub sij hawm ntev kub laus.
