VITON fluorine roj hmab (FKM)

Cov roj hmab uas muaj fluorine hauv cov molecule muaj ntau hom nyob ntawm cov ntsiab lus fluorine, uas yog, cov qauv monomer; Tam sim no dav siv fluorine roj hmab ntawm hexafluoride series yog thawj zaug teev los ntawm DuPont nyob rau hauv lub npe lag luam "VITON". Kev kub siab ua haujlwm zoo dua li cov roj hmab silicone …… Cov tshuaj tiv thaiv, tsis kam rau cov roj thiab cov kuab tshuaj feem ntau (tshwj tsis yog ketones thiab esters), huab cua tsis kam, ozone kuj zoo, tab sis txias tsis kam; Feem ntau dav siv hauv tsheb, maus taus, B thiab lwm yam khoom, thiab cov ntsaws ruaj ruaj hauv cov nroj tsuag tshuaj Cov kev khiav hauj lwm kub yog -20 degree -260 degree . Thaum qhov kub thiab txias yog qhov yuav tsum tau muaj, muaj qhov ntsuas kub tsis tshua muaj siab uas tuaj yeem siv mus txog -40 degree, uas yog tus nqi siab dua.

NBR (nitrile butadiene roj hmab)

yog ua los ntawm butadiene thiab acrylonitrile los ntawm emulsion polymerization. Nitrile roj hmab feem ntau yog tsim los ntawm qhov kub thiab txias emulsion polymerization. Nws muaj cov roj ua haujlwm zoo heev, siab ua haujlwm tsis zoo, ua haujlwm kub zoo thiab muaj zog adhesion. Nws qhov tsis zoo yog qhov tsis zoo ntawm qhov kub thiab txias, tsis zoo ozone tsis kam, tsis zoo hluav taws xob, thiab qis elasticity me ntsis.

Tsis tas li ntawd, nws kuj muaj dej tsis kam, huab cua nruj thiab zoo heev kev sib raug zoo zog. Siv dav hauv kev tsim cov khoom siv roj hmab ntau yam, ntau yam roj-resistant gaskets, gaskets, casings, saj zawg zog ntim, saj zawg zog hoses, luam ntawv thiab dyeing roj hmab rollers, cable roj hmab cov ntaub ntawv, thiab lwm yam. Nws tau dhau los ua indispensable nyob rau hauv industries xws li xws li tsheb, aviation, roj av, thiab luam ntawv. Cov khoom siv elastic.

Nitrile roj hmab muaj cov roj ua haujlwm zoo heev, nws cov roj kuj yog qhov thib ob tsuas yog cov roj hmab polysulfide thiab fluoro roj hmab, thiab muaj kev puas tsuaj thiab huab cua nruj. Qhov tsis zoo ntawm nitrile roj hmab yog tias nws tsis tiv taus ozone thiab aromatics, halogenated hydrocarbons, ketones thiab ester hnyav, thiab tsis haum rau cov ntaub ntawv insulating.

Lub hom phiaj tseem ceeb:

Cov roj hmab Nitrile feem ntau yog siv los ua cov khoom siv roj-resistant, xws li roj-resistant kav, tapes, roj hmab diaphragms, thiab cov hnab roj hmab loj. Nws yog feem ntau siv los ua ntau yam roj-resistant molded khoom, xws li O-rings, roj foob, khob, diaphragms, li qub, hauv qab, thiab lwm yam. Nws kuj yog siv los ua cov ntawv roj hmab thiab cov khoom hnav-resistant.

EPDM (Ethylene-Propylene-Diene Monomer)

EPDM roj hmab yog terpolymer ntawm ethylene, propylene thiab non-conjugated diene. Kev tsim khoom lag luam pib xyoo 1963. Kev noj txhua xyoo thoob ntiaj teb yog 800,000 tons. Qhov tseem ceeb tshaj plaws ntawm EPDM yog nws cov kev tiv thaiv zoo tshaj rau oxidation, ozone thiab corrosion. Txij li thaum EPDM belongs rau tsev neeg polyolefin, nws muaj vulcanization zoo heev. Ntawm tag nrho cov roj hmab, EPDM muaj lub ntiajteb txawj nqus tshwj xeeb. Nws tuaj yeem nqus tau ntau ntawm cov muab tub lim thiab roj yam tsis muaj kev cuam tshuam rau cov yam ntxwv. Yog li ntawd, cov khoom siv roj hmab uas tsis muaj nqi tuaj yeem tsim tau.
