Irabha yendaloilungele amanzi, amanzi olwandle, umoya, igesi engasebenziyo, ialkali, isisombululo setyuwa emanzi kunye nezinye imidiya, kodwa ayixhathisi kwi-oyile yezimbiwa kunye nezinyibilikisi ezingezizo ipolar, ubushushu bokusetyenziswa kwexesha elide alidluli kwi-90 ℃, ukusebenza kobushushu obuphantsi kuhle kakhulu. , ingasetyenziswa ngaphezulu kwe -60℃.

  Irabha yeNitrileilungele iimveliso zepetroleum, ezifana ne-petroleum, i-oyile yokuthambisa, i-oyile yamafutha, njl., ubushushu bokusetyenziswa kwexesha elide yi-120 ℃, njengakwi-oyile eshushu inokumelana ne-150℃, ubushushu obuphantsi ngu-10~-20℃.

  Irabha yeNeopreneilungele amanzi olwandle, iasidi ebuthathaka, ialkali ebuthathaka, isisombululo setyuwa, ukuxhathisa okugqwesileyo kwioksijini kunye nokuguga kwe-ozone, ukuxhathisa kwe-oyile kungaphantsi kwerabha ye-nitrile kwaye ingcono kunezinye irabha ngokubanzi, ubushushu bokusetyenziswa kwexesha elide ngaphantsi kwe-90 ℃, ubushushu bokusetyenziswa okuphezulu abunayo. idlula i-130 ℃, ubushushu obuphantsi yi -30~-50 ℃.

Kukho iintlobo ezininzi zeirabha yefluorine, banokuxhathisa okulungileyo kwe-asidi, ukuxhathisa i-oxidation kunye nokuxhatshazwa kweoli, ukuxhathisa i-solvent. Ingasetyenziswa phantse kuzo zonke imidiya yeasidi kwakunye neeoli ezithile kunye nezinyibilikisi, ubushushu bokusetyenziswa kwexesha elide ngaphantsi kwe200℃.

Iphepha lerabha njenge-gasket ye-flange, esetyenziswa kakhulu kwimibhobho okanye imingxuma ehlala ichithwa rhoqo, imingxuma yezandla, uxinzelelo aludluli kwi-1.568MPa. Ngenxa yokuba kuzo zonke iintlobo zee-gaskets, i-rubber gaskets yeyona nto ithambileyo, intsebenziswano efanelekileyo yokusebenza, kwaye inokudlala umphumo wokutywina phantsi kwamandla amancinci okulayisha kwangaphambili. Ngenxa yoko, xa uphantsi koxinzelelo lwangaphakathi, kulula ukukhanywa ngenxa yobunzima okanye ubunzima obuphantsi be-gasket.

Iphepha lerabha elisetyenziswa kwibenzene, iketone, iether kunye nezinye izinyibilikisi eziphilayo, kulula ukubonakala ukudumba, ukufumana ubunzima, into ethambileyo, encangathi, ekhokelela ekungaphumeleli kokutywinwa. Ngokuqhelekileyo, ukuba idigri yokuvuvukala idlula i-30%, ayinakusetyenziswa.

Kwimeko yoxinzelelo oluphantsi (ngokukodwa ngaphantsi kwe-0.6MPa) kunye ne-vacuum, ukusetyenziswa kweepads zerabha kulungeleka ngakumbi. Izinto zerabha zinobuninzi obuhle kunye nokunyanzeliswa okuphantsi. Ngokomzekelo, i-rubber ye-fluorine ifaneleke kakhulu ukutywinwa kweegaskets ze-vacuum containers, kwaye i-vacuum degree ifikelela kwi-1.3 × 10-7Pa. Xa i-rubber pad isetyenziswe kwi-vacuum degree degree ye-10-1 ~ 10-7Pa, idinga ukubhaka kunye nokumpontshwa.
