1, tus da dej hose tseem hu ua da dej hose, nws yog qhov txuas ntawm tus pas da dej thiab tus faucet. Cov dej da dej dav dav yog ua los ntawm EPDM cov raj sab hauv, kub resistant nylon core thiab 304 stainless hlau sab nrauv raj, cov txiv ntseej yog ua los ntawm cam khwb cia tooj liab thiab lub gasket yog ua los ntawm nitrile roj hmab (NBR). EPDM roj hmab belongs rau copolymer, ethylene, propylene hlawv thiab tsis-co-choked diolefin los ntawm cov tshuaj co-polymerization ntawm roj hmab.
2, ua ntej ntawm tag nrho cov, kev laus kuj, tsis kam mus rau dej kub kev ua tau zoo heev, EPDM muaj zoo heev huab cua tsis kam, ozone kuj, acid thiab alkali tsis kam, thiab nyob rau hauv 125 degree C superheated dej immersion rau 15 lub hlis, lub mechanical zog ntawm kev hloov yog me me heev, ntim expansion tus nqi tsuas yog 0.3 feem pua . Da dej vim qhov xav tau rau cov dej kub mus ntev los ntawm kev siv EPDM ua lub hose yog cov khoom siv zoo tshaj plaws.
3, qhov thib ob yog qhov elasticity, peb txhua tus paub tias thaum siv tes tuav da dej xav tau kom ncab kom yaug lub cev, thiab EPDM cov saw hlau molecular tuaj yeem khaws cia rau hauv ntau qhov kev hloov pauv, nyob rau hauv txoj haujlwm qis tseem tuaj yeem khaws cia, yog li Qhov no yog ib qho ntawm cov laj thawj tseem ceeb uas cov neeg tsim qauv xaiv EPDM.
