Tam sim no muaj peb feem ntau siv cov khoom sib khi rau solenoid li qub:
NBR (Nitrile Butadiene Roj Hmab)
NBR yog tsim los ntawm emulsion polymerization ntawm butadiene thiab acrylonitrile. Nws yog tsim los siv tsawg-kub emulsion polymerization thiab muaj cov roj ua haujlwm zoo, hnav tsis kam, ua haujlwm kub zoo, thiab muaj zog adhesion. Nws qhov tsis zoo suav nrog qhov tsis zoo - kub tsis kam, tsis zoo ozone tsis kam, tsis zoo hluav taws xob, thiab qis elasticity me ntsis.
EPDM (Ethylene Propylene Diene Monomer)
EPDM yog terpolymer ntawm ethylene, propylene, thiab tsis yog -conjugated diene. Kev tsim khoom lag luam pib xyoo 1963. Kev siv thoob ntiaj teb yog 800,000 tons ib xyoos twg. EPDM cov yam ntxwv tseem ceeb tshaj plaws yog nws cov kev tiv thaiv zoo tshaj rau oxidation, ozone, thiab corrosion. Raws li EPDM belongs rau tsev neeg polyolefin, nws muaj vulcanization zoo heev. Ntawm tag nrho cov roj hmab, EPDM muaj qhov qis tshaj qhov tshwj xeeb. Nws tuaj yeem nqus tau ntau ntawm cov fillers thiab cov roj uas muaj feem cuam tshuam rau nws cov khoom. Yog li ntawd, nws tuaj yeem siv los tsim cov khoom siv roj hmab qis.
VITON Fluororubber (FKM)
Fluororubbers uas muaj fluorine nyob rau hauv lawv cov molecules tuaj nyob rau hauv ntau yam nyob ntawm seb cov ntsiab lus fluorine thiab monomer qauv. Hexafluorinated fluororubbers pom zoo siab dua - kub tsis kam tshaj silicone roj hmab, thiab muaj cov tshuaj tiv thaiv zoo heev, tiv taus cov roj thiab cov kuab tshuaj feem ntau (tshwj tsis yog ketones thiab esters), huab cua tsis kam, thiab ozone tsis kam, tab sis tsis txias txias - tiv taus cov khoom. Lawv tau dav siv hauv tsheb, maus taus, thiab tshuaj cog cov khoom sib khi, nrog rau kev ua haujlwm kub ntawm -20℃txog 260℃. Rau qis- daim ntawv thov kub, cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob muaj peev xwm ua haujlwm tau mus txog -40 degree, tab sis cov no kim dua.
