Kugwiritsa ntchito pepala la mphira wa asibesitosi pamakampani osindikiza ma valve kuli ndi zabwino izi:

Mtengo wotsika: Poyerekeza ndi zida zina zosindikizira zapamwamba kwambiri, mtengo wa pepala la mphira wa asbestosi ndiwotsika mtengo.

Kukana kwa Chemical: Chipepala cha mphira wa asibesitosi chimakhala ndi kukana kwa dzimbiri kwa sing'anga yokhala ndi mankhwala ocheperako, omwe amatha kukwaniritsa zofunikira pakugwira ntchito.

Kukonza kosavuta: Chifukwa pepala la mphira la asbestosi ndilosavuta kukonza ndikusintha, ndilosavuta kukonza valavu.

Vuto lalikulu la pepala la mphira wa asbestosi ndikuti ngakhale zinthu za gasket zimawonjezeredwa ndi mphira ndi zodzaza zina, sizingathe kudzaza ma pores ang'onoang'ono omwe amalumikizana, ndipo pali njira yolowera. Chifukwa chake, m'malo oipitsa kwambiri, ngakhale kupanikizika ndi kutentha sikuli kokwera, sizingagwiritsidwe ntchito. Akagwiritsidwa ntchito muzinthu zina zamafuta otentha kwambiri, nthawi zambiri pakapita nthawi, chifukwa cha carbonization ya mphira ndi filler, mphamvu imachepetsedwa, zinthuzo zimakhala zotayirira, ndipo pali malowedwe pa mawonekedwe ndi mkati mwa gasket, ndipo pali coking ndi utsi. Kuonjezera apo, pepala la mphira wa asibesitosi limamangirizidwa mosavuta ku flange yosindikiza pamwamba pa kutentha kwakukulu, zomwe zimabweretsa mavuto ambiri m'malo mwa gasket.

M'malo otentha, kuthamanga kwa gasket muzofalitsa zosiyanasiyana kumadalira mphamvu yosungira mphamvu ya zinthu za gasket. Pali madzi akristalo ndi madzi adsorbed mu asbestos fiber material. Pa 110 ℃, 2/3 ya madzi adsorbed pakati pa ulusi wayamba, ndipo kulimba kwa ulusiwo kumachepetsedwa ndi 10%. Pa 368 ℃, madzi onse adsorbed amatuluka, ndipo kulimba kwa ulusi kumachepetsedwa ndi 20%. Pamwamba pa 500 ℃, madzi a crystalline amayamba kugwa, ndipo mphamvu imakhala yochepa.

Asibesitosi mphira pepala lili chloride ayoni ndi sulfide, zosavuta dzimbiri maselo galvanic ndi zitsulo flanges pambuyo mayamwidwe madzi, makamaka sulfure zili mafuta zosagwira asibesito labala pepala ndi kangapo kuposa wamba asbestosi mphira pepala, kotero si oyenera ntchito sanali mafuta TV. Ma gaskets adzakula mumafuta ndi zosungunulira, koma mkati mwamitundu ina, palibe chomwe chimakhudza kusindikiza.

Komabe, ndikofunikira kuzindikira kuti asibesitosi adadziwika kuti ndi chinthu chowopsa, ndipo kugwiritsa ntchito mapepala a mphira a asibesitosi kumatha kubweretsa zoopsa ku thanzi komanso chilengedwe.
