1. NBR (irabha ye-nitrile butadiene)
Ivalve ye-solenoid yenziwe nge-butadiene kunye ne-acrylonitrile nge-emulsion polymerization.Irabha yeNitrile iveliswa ikakhulu yipolymerization yobushushu obuphantsi be-emulsion.Inokumelana ne-oyile okugqwesileyo, ukumelana nokunxiba okuphezulu, ukumelana nobushushu obuhle kunye nokuncamathela okuqinileyo.Izinto ezingeloncedo kukunganyangeki kobushushu obuphantsi, ukunganyangeki kwe-ozone, iipropathi zombane ezilambathayo kunye ne-elastic esezantsi kancinane.
Usetyenziso oluphambili lwevalve ye-solenoid: irabha ye-solenoid ye-nitrile isetyenziswa ikakhulu ukwenza iimveliso ezinganyangekiyo kwi-oyile, iivalvu ze-solenoid ezinjengemibhobho enganyangekiyo kwi-oyile, iiteyiphu, iidiaphragm zerabha kunye nezinyini ze-oyile ezinkulu, njl. iimveliso ezibunjiweyo, ezifana ne-O-rings, izitywina ze-oyile, izitya zesikhumba, i-diaphragms, iivalvu, ii-bellows, njl.
2. EPDM EPDM (Ethylene-Propylene-Diene Monomer)
Uphawu oluphambili lwe-valve ye-solenoid EPDMZ kukuxhathisa kwayo ngokugqwesileyo kwi-oxidation, i-ozone kunye nokukhukuliseka.Ekubeni i-EPDM iyeyentsapho ye-pololefin, ineempawu ezibalaseleyo ze-vulcanization.I-Solenoid Valve Phakathi kwazo zonke iirubha, i-EPDM inobunzima obuthile obuphantsi.I-valve ye-solenoid inokuthatha inani elikhulu lokupakisha kunye neoli ngaphandle kokuchaphazela iimpawu.Ngoko ke, i-compound yerabha enexabiso eliphantsi inokuveliswa.
I-valve ye-Solenoid isakhiwo se-molecular kunye neempawu: I-EPDM i-terpolymer ye-ethylene, i-propylene kunye ne-non-conjugated diene.I-Diolefins inesakhiwo esikhethekileyo, i-valve ye-solenoid inokuthi i-copolymerize enye yeebhondi ezimbini, kwaye i-double bonds engaxutywanga isetyenziswa kakhulu njenge-cross-link.Enye i-unsaturated ayiyi kuba yi-polymer backbone, kuphela amatyathanga asecaleni.Eyona chain yepolymer ye-EPDM igcwele ngokupheleleyo.Olu phawu lwevalve ye-solenoid yenza i-EPDM ixhathise ukushisa, ukukhanya, i-oksijini, kwaye ngakumbi i-ozone.I-EPDM i-nonpolar in nature, iyamelana nezisombululo ze-polar kunye neekhemikhali, ine-low water absorption, kwaye ineempawu ezintle zokugquma.Iimpawu zevalve ye-Solenoid: ① ingxinano ephantsi kunye nokuzaliswa okuphezulu;② ukuxhathisa ukwaluphala;③ ukuxhathisa umhlwa;④ ukumelana nomphunga wamanzi;⑤ ukumelana nobushushu;⑥ iimpawu zombane;⑦ ukuqina;
3. Irabha ye-VITON fluorine (FKM)
I-rubber ene-fluorine kwi-molecule ye-valve ye-solenoid ineentlobo ezahlukeneyo ngokomxholo we-fluorine, oko kukuthi, isakhiwo se-monomer;Irabha ye-fluorine yochungechunge lwe-hexafluoride yevalve ye-solenoid inokumelana nobushushu obuphezulu kunye nokumelana neekhemikhali kunerubha ye-silicone, kwaye ivalve ye-solenoid iyaxhathisa kuninzi lwe-oyile kunye nezinyibilikisi (ngaphandle kwee-ketones kunye ne-esters), ukumelana nemozulu elungileyo kunye nokumelana ne-ozone, kodwa ukumelana nokubanda kakubi;iivalve solenoid ngokubanzi zisetyenziswa ngokubanzi kwiimoto, iimveliso B-class, kunye netywina kwizityalo imichiza, kwaye ubushushu bokusebenza uluhlu -20 ℃ ℃ 260 ℃, xa ubushushu obuphantsi kufuneka, kukho uhlobo lobushushu eliphantsi ukumelana ezinokusetyenziswa. ukuya kuthi ga ku -40 ℃, kodwa ixabiso liphezulu.
