1. NBR (nitrile butadiene roj hmab)
Lub solenoid valve yog ua los ntawm butadiene thiab acrylonitrile los ntawm emulsion polymerization.Nitrile roj hmab yog tsim los ntawm qhov kub thiab txias emulsion polymerization.Nws muaj cov roj ua haujlwm zoo heev, siab hnav tsis kam, zoo kub ua haujlwm thiab muaj zog adhesion.Qhov tsis zoo yog qhov tsis zoo ntawm qhov kub thiab txias, tsis zoo ozone tsis kam, tsis muaj hluav taws xob tsis zoo thiab qis elasticity me ntsis.
Kev siv lub ntsiab ntawm solenoid valve: solenoid valve nitrile roj hmab feem ntau yog siv los ua cov khoom siv roj-resistant, solenoid li qub xws li roj-resistant kav, tapes, roj hmab diaphragms thiab loj roj zais zis, thiab lwm yam, feem ntau yog siv los ua ntau yam roj-resistant. molded cov khoom, xws li O-rings, roj foob, tawv tais, diaphragms, li qub, bellows, thiab lwm yam., kuj yog siv los ua cov ntawv roj hmab thiab cov khoom hnav-resistant.
2. EPDM EPDM (Ethylene-Propylene-Diene Monomer)
Lub ntsiab yam ntxwv ntawm lub solenoid valve EPDMZ yog nws zoo heev tiv thaiv oxidation, ozone thiab yaig.Txij li thaum EPDM belongs rau tsev neeg polyolefin, nws muaj cov yam ntxwv zoo vulcanization.Solenoid Valve Ntawm tag nrho cov roj hmab, EPDM muaj qhov qis tshaj qhov tshwj xeeb.Lub solenoid valve tuaj yeem nqus tau ntau qhov ntim 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.
Solenoid valve molecular qauv thiab cov yam ntxwv: EPDM yog terpolymer ntawm ethylene, propylene thiab non-conjugated diene.Diolefins muaj cov qauv tshwj xeeb, lub solenoid valve tuaj yeem tsuas yog copolymerize nrog ib qho ntawm ob daim ntawv cog lus, thiab ob daim ntawv cog lus unsaturated feem ntau yog siv los ntawm kev sib txuas.Lwm qhov tsis txaus ntseeg yuav tsis dhau los ua cov pob txha polymer, tsuas yog cov saw hlau sab.Lub ntsiab polymer saw ntawm EPDM yog tag nrho saturated.Cov yam ntxwv ntawm lub solenoid valve no ua rau EPDM tiv taus cua sov, lub teeb, oxygen, thiab tshwj xeeb tshaj yog ozone.EPDM yog nonpolar nyob rau hauv cov xwm, resistant rau polar daws thiab tshuaj, muaj tsawg dej nqus, thiab muaj zoo insulating zog.Cov yam ntxwv ntawm solenoid valve: ① tsawg ntom thiab siab filling;② kev laus tsis kam;③ corrosion kuj;④ dej vapor kuj;⑤ superheat tsis kam;⑥ cov khoom hluav taws xob;⑦ elasticity;
3. VITON fluorine roj hmab (FKM)
Cov roj hmab uas muaj fluorine nyob rau hauv cov molecule ntawm lub solenoid valve muaj ntau hom raws li cov ntsiab lus fluorine, uas yog, cov qauv monomer;fluorine roj hmab ntawm hexafluoride series ntawm lub solenoid valve muaj qhov kub thiab txias tsis kam thiab tshuaj tiv thaiv zoo dua li cov roj hmab silicone, thiab lub solenoid valve yog resistant rau feem ntau cov roj thiab cov kuab tshuaj (tshwj tsis yog ketones thiab esters), huab cua tsis zoo thiab ozone tsis kam, tab sis tsis zoo txias tsis kam;solenoid li qub feem ntau yog siv dav hauv tsheb, B-chav khoom, thiab cov ntsaws ruaj ruaj hauv cov nroj tsuag tshuaj, thiab kev khiav hauj lwm kub yog -20 ℃ ~ 260 ℃, thaum tsis kub yuav tsum tau, muaj ib tug tsis tshua muaj kub resistant hom uas yuav siv tau. mus txog -40 ℃, tab sis tus nqi siab dua.
