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 pakatha nthawi yogwiritsidwa ntchito, chifukwa cha mphira wa mphira ndi kudzaza, mphamvu imachepetsedwa, zinthuzo zimakhala zotayirira, ndipo pali malowedwe pa mawonekedwe ndi mkati mwa gasket, ndi pali kuphika ndi kusuta. 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.

Tsamba labala la asibesitosi lili ndi ayoni a chloride ndi sulfide, zosavuta kupanga dzimbiri ma cell a galvanic okhala ndi zitsulo zachitsulo pambuyo pa kuyamwa kwamadzi, makamaka sulfure wamafuta osamva mphira wa asbestosi ndipamwamba kangapo kuposa pepala wamba la asbestosi, kotero siwoyenera. kuti agwiritsidwe ntchito muzofalitsa zopanda mafuta. 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.
