Kev sib piv ntawm cov roj hmab EPDM thiab cov roj hmab silicone

Ob qho roj hmab EPDM thiab roj hmab silicone siv tau rau cov raj txias thiab cov raj cua sov. Qhov txawv ntawm ob yam khoom no yog dab tsi?

1. Hais txog tus nqi: Cov khoom siv roj hmab EPDM pheej yig dua li cov khoom siv roj hmab silicone.

2. Hais txog kev ua tiav: Cov roj hmab silicone zoo dua li EPDM.

3. Hais txog kev tiv taus kub: roj hmab silicone muaj kev tiv taus kub zoo dua, roj hmab EPDM muaj kev tiv taus kub ntawm 150 ° C, thiab roj hmab silicon muaj kev tiv taus kub ntawm 200 ° C.

4. Kev tiv thaiv huab cua: Cov roj hmab ethylene-propylene zoo dua tiv thaiv huab cua, thiab cov roj hmab nws tus kheej yog tus phooj ywg ib puag ncig, tab sis nyob rau hauv ib puag ncig noo noo, cov roj hmab ethylene-propylene yuav tsis tshua muaj kab mob yug me nyuam.

5. Qhov sib piv ntawm qhov sib txawv ntawm qhov sib txawv: tam sim no qhov sib piv ntawm qhov sib txawv ntawm cov roj hmab silicone txias ntsws tubing siab dua li ntawm EPDM txias ntsws tubing.

6. Qhov sib txawv ntawm kev sib xyaw ua ke: Thaum hlawv, cov roj hmab silicone yuav tso tawm hluav taws ci ntsa iab, yuav luag tsis muaj pa luam yeeb, tsis muaj ntxhiab tsw, thiab cov seem dawb tom qab hlawv. EPDM, tsis muaj qhov xwm txheej zoo li no.

7. Hais txog kev tearing thiab puncture resistance: EPDM zoo dua.

8. Lwm yam: Ethylene-propylene roj hmab muaj ozone zoo thiab muaj zog; siab hardness thiab tsis zoo tsawg kub brittleness; silica gel muaj zoo elasticity thiab zoo tsawg kub; ozone ib txwm muaj, tsis muaj zog!
