Npauj Npaim Valve Roj Hmab Rooj Ring

NBR

-35 degree ~ 100 degree

Nitrile butadiene roj hmab muaj cov khoom zoo xws li kev nthuav dav ntawm tus kheej, kev puas tsuaj thiab tiv thaiv hydrocarbons. Raws li cov khoom siv dav dav, nws tuaj yeem siv rau hauv dej, nqus tsev, kua qaub, ntsev, alkali, roj, roj, butter, roj hydraulic, glycol thiab lwm yam xov xwm, tab sis nws tsis tuaj yeem siv hauv acetone, ketone, nitrate, thiab fluorinated hydrocarbons.

EPDM

-40 degree ~ 135 degree

Ethylene propylene roj hmab yog cov roj hmab hluavtaws zoo, uas tuaj yeem siv rau hauv cov dej kub, dej haus, khoom noj siv mis, ketone, cawv, nitrate roj, glycerin thiab lwm yam xov xwm, tab sis tsis tuaj yeem siv rau hauv cov roj hydrocarbon, cov tshuaj inorganic lossis cov kuab tshuaj.

CR

-35 degree ~ 100 degree

Neoprene roj hmab tuaj yeem siv rau hauv cov kua qaub, roj, roj, butter, hnyav thiab lwm yam xov xwm uas muaj kev cuam tshuam zoo.

FKM

-20 degree ~ 200 degree

Fluorine roj hmab yog ib hom fluorinated hydrocarbon roj hmab uas muaj kev tiv thaiv zoo rau hydrocarbon puag roj, roj roj thiab lwm yam khoom siv roj av. Nws yog qhov tsim nyog rau dej, roj, cua, kua qaub thiab lwm yam xov xwm, tab sis tsis tuaj yeem siv rau hauv chav dej, dej kub lossis cov ntsiab lus alkali siab tshaj 82 degree.

Silicone

-70 degree ~ 200 degree

Silicone roj hmab tiv taus qhov kub thiab txias, tsis tshua muaj kub thiab muaj tshuaj lom neeg ruaj khov, thiab siv dav hauv cov kua qaub, tsis muaj zog alkali, khoom noj khoom haus thiab lwm yam lag luam.

Cov ntaub ntawv tshwj xeeb: carboxyl nitrile roj hmab, hydrogenated nitrile roj hmab, corrosion resistant ethylene propylene roj hmab, chav fluororubber, chlorosulfonated polyethylene, thiab lwm yam.
