Labala wachilengedwendi oyenera madzi, madzi a m'nyanja, mpweya, inert gasi, zamchere, mchere amadzimadzi njira ndi zina TV, koma osagonjetsedwa ndi mchere mafuta ndi zosungunulira non-polar, kutentha ntchito yaitali si upambana 90 ℃, otsika kutentha ntchito ndi zabwino kwambiri. , angagwiritsidwe ntchito pamwamba -60 ℃.

  Mpira wa Nitrilendi oyenera mafuta mafuta, monga mafuta, lubricating mafuta, mafuta mafuta, etc., yaitali ntchito kutentha ndi 120 ℃, monga mafuta otentha akhoza kupirira 150 ℃, kutentha otsika ndi -10 ~ -20 ℃.

  Mpira wa Neoprenendi oyenera madzi a m'nyanja, asidi ofooka, ofooka alkali, mchere njira, kukana kwambiri mpweya ndi ozoni kukalamba, kukana mafuta ndi otsika kwa mphira nitrile ndi kuposa mphira ena ambiri, kutentha ntchito yaitali pansi 90 ℃, kutentha ntchito pazipita si. kuposa 130 ℃, kutentha otsika ndi -30 ~ -50 ℃.

Pali mitundu yambiri yamphira wa fluorine, ali ndi kukana bwino kwa asidi, kukana kwa okosijeni ndi kukana mafuta, kukana zosungunulira. Angagwiritsidwe ntchito pafupifupi onse TV TV komanso mafuta ndi zosungunulira, ntchito yaitali kutentha m'munsimu 200 ℃.

Pepala la mphira ngati gasket flange, makamaka ntchito mapaipi kapena nthawi zambiri disassembled maenje, mabowo m'manja, kuthamanga si upambana 1.568MPa. Chifukwa mu mitundu yonse ya ma gaskets, ma gaskets a rabara ndi ofewa kwambiri, ogwirizana bwino, ndipo amatha kuchitapo kanthu kusindikiza pansi pa mphamvu yaing'ono yotsegula. Chifukwa cha ichi, pamene akukakamizidwa mkati, n'zosavuta kufinya chifukwa cha makulidwe kapena kuuma kochepa kwa gasket.

Pepala lamphira lomwe limagwiritsidwa ntchito mu benzene, ketone, etha ndi zosungunulira zina organic, kuwoneka kosavuta kutupa, kunenepa, zofewa, zomata, zomwe zimapangitsa kuti chisindikizo chilephereke. Nthawi zambiri, ngati kuchuluka kwa kutupa kumapitilira 30%, sikungagwiritsidwe ntchito.

Pankhani ya kutsika kwapansi (makamaka pansi pa 0.6MPa) ndi vacuum, kugwiritsa ntchito mapepala a mphira ndikoyenera kwambiri. Zida za mphira zimakhala ndi kachulukidwe wabwino komanso kutsika kochepa. Mwachitsanzo, mphira wa fluorine ndi woyenera kwambiri kusindikiza ma gaskets okhala ndi vacuum, ndi digiri ya vacuum mpaka 1.3 × 10-7Pa. Pamene pad mphira ntchito vacuum digiri osiyanasiyana 10-1 ~ 10-7Pa, ayenera kuphika ndi kupopera.
