Kev xaiv cov khoom siv gasket 1
NR muaj corrosion kuj zoo rau cov tsis muaj zog acid thiab alkali, ntsev thiab chloride daws, tab sis tsis zoo corrosion kuj rau roj thiab hnyav, thiab tsis pom zoo rau ozone nruab nrab. Pom zoo ua haujlwm kub: -57 degree C txog 93 degree C.
CR yog cov roj hmab hluavtaws yoog kom tiv thaiv corrosion ntawm cov kua qaub nruab nrab corrosive, puag thiab ntsev daws. Zoo corrosion kuj rau kev lag luam roj thiab roj. Tab sis qhov corrosion kuj ntawm muaj zog oxidizing acids, aromatic hydrocarbons thiab chlorinated hydrocarbons tsis zoo. Pom zoo ua haujlwm kub -51 degree C txog 121 degree C.
NBR yog cov roj hmab hluavtaws tsim nyog rau ntau qhov kub thiab txias nrog kev tiv thaiv corrosion zoo rau cov roj, cov kuab tshuaj, cov tshuaj tsw qab hydrocarbons, alkaline hydrocarbons, roj thiab cov nkev. Zoo corrosion kuj rau hydroxides, ntsev thiab ze li ntawm nruab nrab acids. Tab sis nyob rau hauv muaj zog oxidizing nruab nrab, chlorinated hydrocarbons, ketones thiab lipids nws corrosion kuj tsis zoo, pom zoo ua hauj lwm kub 51 degree ~ 121 degree.
Viton yog ua los ntawm binary thiab ternary fluorine roj hmab uas muaj cov khoom sib xyaw, vulcanizing tus neeg sawv cev los ntawm kev sib xyaw. Ntxiv rau qhov ua tau zoo thaum tshav kub kub, nruab nrab tsis kam, thiab zoo lub cev thiab txhua yam khoom, tab sis kuj muaj qhov tsis tshua muaj compression mus tas li deformation, zoo elasticity thiab kev pab lub neej ntev. Cov roj hmab fluorine muaj qhov ua kom sov zoo (200 ~ 250 degree), roj tsis kam, tuaj yeem siv rau hauv kev tsim lub tog raj kheej liner sealing nplhaib, roj hmab lub tais thiab lub ntsej muag lub ntsej muag, tuaj yeem txhim kho lub sijhawm ua haujlwm. Pom zoo ua haujlwm kub: -40 degree C txog 232 degree C.
