EPDM Roj Hmab O Rings

EPDM O Ring yog ib hom nplhaib foob ua los ntawm ternary ethylene propylene roj hmab. EPDM roj hmab paub txog nws txoj kev laus zoo heev, ozone tsis kam, siab -kub kub tsis kam thiab tshuaj lom neeg ruaj khov zoo heev. Nws yog ib qho tseem ceeb static thiab dynamic sealing tov nyob rau hauv tsheb, HVAC, sanitary chaw thiab ntau yam kev siv.
Loj: Standard thiab customized ua.

COV CHAW UA HAUJ LWM THIAB ZOO

1. Zoo heev huab cua tsis kam thiab ozone kuj

Kev ua tau zoo nyob rau sab nraum zoov huab cua (ultraviolet, nag thiab daus, ozone) ib puag ncig, kev siv sijhawm ntev - tsis yooj yim rau tawg thiab tawv, thiab muaj lub neej ua haujlwm ntev. Nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv pib thiab cov khoom siv sab nraum zoov.

2. Zoo heev -kub tsis kam

Nws tuaj yeem ua haujlwm ntev nyob rau hauv qhov chaw muaj dej txaus txog li 150℃txog 170 degree, thiab yog cov khoom siv sib khi zoo tshaj plaws rau cov dej kub thiab chav dej.

3. Ntau yam ntawm kev siv kub

Qhov ntsuas kub ua haujlwm ntawm tus qauv qauv yog li -55℃rau +125℃. Cov mis tshwj xeeb tuaj yeem nthuav dav ntxiv.

4. Zoo tshuaj stability

Kev tiv thaiv zoo rau cov tshuaj polar, suav nrog:
Txhua yam dej xov xwm: dej kub, dej txias, dej hiav txwv, coolant (ethylene glycol / propylene glycol pawg).
Detergents: alkaline detergent, dej soapy.
Qee cov kua qaub thiab alkalis (dilute tov).
Dej cawv, roj silicone thiab roj silicone.

5. Cov hluav taws xob rwb thaiv tsev zoo heev

Nrog cov hluav taws xob tsis tshua muaj hluav taws xob, nws tsim nyog rau kev sib khi hluav taws xob thiab rwb thaiv tsev lub sijhawm.

6. Zoo elasticity thiab compression mus tas li deformation kev ua tau zoo

Nws tuaj yeem muab kev sib khi ruaj khov thiab kav ntev, uas tuaj yeem kho cov duab zoo thiab tuav cov nyhuv sealing txawm tias tom qab lub siab tas mus li.
