Zida zitatu zosindikizira zodziwika bwino zama valve solenoid

1. NBR (rabala wa nitrile butadiene)

Valavu ya solenoid imapangidwa ndi butadiene ndi acrylonitrile ndi emulsion polymerization.Nitrile mphira makamaka opangidwa ndi otsika kutentha emulsion polymerization.Ili ndi kukana kwambiri kwamafuta, kukana kwambiri kuvala, kukana kutentha kwabwino komanso kumamatira mwamphamvu.Zoyipa zake ndi kukana kutentha kochepa, kukana kwa ozoni, kutsika kwa magetsi komanso kutsika pang'ono.

Kugwiritsa ntchito kwambiri valavu ya solenoid: mphira wa solenoid valve nitrile amagwiritsidwa ntchito makamaka popanga zinthu zosagwira mafuta, ma valve solenoid monga mapaipi osamva mafuta, matepi, ma diaphragms a rabara ndi chikhodzodzo chachikulu chamafuta, ndi zina zambiri, amagwiritsidwa ntchito popanga mafuta osiyanasiyana osamva mafuta. zinthu zopangidwa, monga mphete za O, zisindikizo zamafuta, Mbale zachikopa, ma diaphragms, mavavu, mabelu, ndi zina zotero, amagwiritsidwanso ntchito popanga mapepala a mphira ndi ziwalo zosavala.

2. EPDM EPDM (Ethylene-Propylene-Diene Monomer)

Khalidwe lalikulu la valavu solenoid EPDMZ ndi kukana kwambiri makutidwe ndi okosijeni, ozoni ndi kukokoloka.Popeza EPDM ndi ya banja polyolefin, ali kwambiri vulcanization makhalidwe.Vavu ya Solenoid Pakati pa ma rubber onse, EPDM ili ndi mphamvu yokoka yotsika kwambiri.Valve ya solenoid imatha kuyamwa kuchuluka kwa kulongedza ndi mafuta popanda kukhudza mawonekedwe.Choncho, mphira yotsika mtengo imatha kupangidwa.

Mapangidwe a maselo a solenoid ndi makhalidwe: EPDM ndi terpolymer ya ethylene, propylene ndi diene yopanda conjugated.Ma Diolefins ali ndi mawonekedwe apadera, valavu ya solenoid imatha kuphatikizika ndi imodzi mwazomangira ziwirizo, ndipo zomangira ziwiri zopanda unsaturated zimagwiritsidwa ntchito ngati zolumikizira.Wina wosasunthika sudzakhala msana wa polima, koma maunyolo am'mbali okha.Unyolo waukulu wa polima wa EPDM ndiwodzaza.Chikhalidwe ichi cha valve solenoid chimapangitsa EPDM kugonjetsedwa ndi kutentha, kuwala, mpweya, makamaka ozoni.EPDM ndi yopanda polar mwachilengedwe, yosagwirizana ndi njira za polar ndi mankhwala, imakhala ndi madzi ochepa, ndipo imakhala ndi zinthu zabwino zotetezera.Makhalidwe a valve ya Solenoid: ① kachulukidwe kakang'ono komanso kudzazidwa kwakukulu;② kukana kukalamba;③ kukana dzimbiri;④ kukana kwa nthunzi wamadzi;⑤ kukana kutentha kwakukulu;⑥ magetsi katundu;⑦ elasticity;

3. VITON fluorine rabala (FKM)

Rabara yokhala ndi fluorine mu molekyulu ya valavu ya solenoid ili ndi mitundu yosiyanasiyana malinga ndi zomwe zili ndi fluorine, ndiko kuti, mawonekedwe a monomer;mphira wa fluorine wa mndandanda wa hexafluoride wa valavu ya solenoid ali ndi kutentha kwapamwamba kwambiri komanso kukana kwa mankhwala kuposa mphira wa silikoni, ndi valavu ya solenoid imagonjetsedwa ndi mafuta ambiri ndi zosungunulira (kupatula ma ketoni ndi esters), kukana kwa nyengo yabwino ndi kukana kwa ozoni, koma kukana kuzizira kosauka;mavavu solenoid ambiri chimagwiritsidwa ntchito magalimoto, mankhwala B-kalasi, ndi zisindikizo mu zomera mankhwala, ndi ntchito kutentha osiyanasiyana -20 ℃ ℃ ℃ 260 ℃, pamene kutentha otsika chofunika, pali otsika kutentha zosagwira mtundu angagwiritsidwe ntchito. mpaka -40 ℃, koma mtengo ndi wapamwamba.
