Dab tsi yog EPDM Khoom

Sep 21, 2023

EPDM, los yog Ethylene Propylene Diene Monomer, yog ib qho elastomer uas yog siv rau hauv kev tsim khoom ntawm ntau yam khoom uas yuav tsum tau ua kom sov, huab cua, thiab ozone tsis kam. Cov khoom siv muaj ntau yam thiab tuaj yeem tsim kom haum rau ntau yam kev siv, suav nrog kev siv tsheb, kev tsim kho, hluav taws xob, thiab kev lag luam siv. EPDM yog dav suav hais tias yog ib qho ntawm cov khoom siv polymer feem ntau txhim khu kev qha thiab kav ntev vim nws cov khoom zoo heev.

 

Qhov zoo

 

Cov khoom siv EPDM muaj ntau qhov zoo, suav nrog:

 

1. Weatherability thiab ozone kuj

 

EPDM muaj cov huab cua zoo heev uas ua rau nws tiv taus UV hluav taws xob thiab ozone. Cov yam ntxwv no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv sab nraum zoov uas cov khoom raug cuam tshuam rau huab cua hnyav.

 

2. Thermal stability

 

Cov khoom siv yog tsim rau cov ntawv thov uas yuav tsum tau muaj qhov kub thiab txias. Nws tuaj yeem ua haujlwm tau zoo hauv qhov kub thiab txias ntawm -50 degree txog +150 degree .

 

3. Tshuaj tiv thaiv

 

EPDM yog resistant rau feem ntau acids, alkalis, thiab tshuaj. Qhov kev tiv thaiv no ua rau nws zoo tagnrho rau kev siv hauv kev lag luam xws li kev ua tshuaj lom neeg, roj, thiab roj.

 

4. Cov khoom siv hluav taws xob insulating

 

EPDM yog cov khoom siv hluav taws xob zoo heev, uas ua rau nws zoo meej rau kev siv hluav taws xob. Cov khoom muaj peev xwm tiv taus high voltage thiab muab zoo heev dielectric zog.

 

5. Ntau yam

 

EPDM tuaj yeem tsim kho kom haum rau cov ntawv thov sib txawv, ua rau nws yog ib qho ntawm cov khoom siv polymer ntau yam.
