Zinthu za graphitendi mtundu watsopano wa zinthu zosindikizira, komanso ndi mtundu wofunika kwambiri wazinthu zosindikizira m'makampani ogulitsa mafakitale.Ili ndi kukana kwabwino kwa dzimbiri, kukana kutentha kwambiri komanso kutsika, kukana kwa ma electromagnetic radiation, friction factor yaying'ono, kudzipaka mafuta, elasticity, komanso kutsika kwamadzi ndi mpweya.
Zojambula za graphiteikhoza kudulidwa kapena kusindikizidwa kuchokera ku mbale zoyera za graphite kapena zitsulo (mbale za mano, mbale zafulati, maukonde) kuti zipitirize kulimbikitsa mbale za graphite molingana ndi momwe ntchito ikuyendera.
1. Mawonekedwe a flexible graphite gasket:
1. graphite yoyera kwambiri imakhala ndi mpweya wabwino wa gasi ndi madzi, monga mbale yopyapyala yokhala ndi makulidwe a 0.125mm, mlingo wa helium ndi 2 * 10-1cm3 / s okha.
2. Kukana kutentha kwabwino.Kutentha kwa graphite kusinthasintha sing'anga si hydrolytic ndi -200 ~ 600℃, koma ndikosavuta kukhala oxidized mu sing'anga hydrolytic.
3. Anisotropy: Thermal conduction, electro conductivity and expansion coefficient of flexible graphite ali ndi anisotropy yoonekeratu.
4. Kukaniza kwa UV mwamphamvu.
5. Kukana kwa dzimbiri kwabwino, kukhazikika kwamankhwala kuzinthu zonse zosungunulira mankhwala, esters, nthunzi yamadzi, kuchepetsa media, etc.
Komabe, pali zoletsa zina mu sing'anga ya hydrolysis.
6. Kutsika kochepa, mphamvu zambiri, kufewa kwabwino komanso kupirira.
Kukula kwa kugwiritsa ntchito graphite yosinthika
Ntchito mafakitale chitoliro flanges, exchangers kutentha, valavu chimakwirira, condensers, mpweya amplifiers, mipope utsi, firiji, etc.
Sing'anga yogwiritsidwa ntchito: madzi, nthunzi, mafuta, asidi, alkali, zosungunulira organic, ammonia, haidrojeni, etc.
2. Chitsulo chosapanga dzimbiri chimalimbitsanso gasket ya graphite
Ma gaskets apamwamba kwambiri a graphite, omwe amadziwikanso kuti ma graphite inorganic gaskets, amapangidwa kuchokera kumapepala owonjezera a graphite kapena pansi.Zida zomangira zimatha kukhala pepala lachitsulo lomwe likufunika.Chifukwa mkulu mawotchi mphamvu ya kusintha graphite gaskets, ndi oyenera gaskets ndi diameters ang'onoang'ono, ndi zina kulimbikitsa graphite gaskets kwambiri bwino mawotchi mphamvu.Zinthu zabwino kwambiri monga kukana kwa corrosion resistance, electromagnetic radiation resistance, kukana kutentha kwambiri/kutsika, komanso moyo wautali.
Zowonjezera pagulu la graphite gasket:
1. Chitsulo cha carbon chimalimbitsansographite gasket: mapeto a pepala losinthika la graphite amamangiriridwa ndi chingwe cha carbon steel (0.2mm), ndiyeno pansi, chomwe chimalimbitsa mphamvu zamakina.
2. 304 zitsulo zosapanga dzimbiri zimalimbitsanso graphite gasket: ma graphite flakes osinthika amamangiriridwa mbali zonse za 304 zitsulo zosapanga dzimbiri, zomwe zimakhala ndi mphamvu zamakina kwambiri.Ndiwoyeneranso zazikulu zosiyanasiyana zazikulu ndi mawonekedwe ovuta, komanso ndizosavuta kunyamula.Ndiwotchuka kwambiri ntchito gawo.Mitundu yosiyanasiyana ya gaskets.
3. 316 zitsulo zosapanga dzimbiri zimalimbitsanso gasket ya graphite: imakhala ndi kukana kwa dzimbiri komanso mphamvu ya kutentha kwambiri, koma mtengo wake ndi wotsika kuposa zida zina.
3. Metal graphite wolukidwa mu gasket
Ma gaskets opangidwa ndi zitsulo ndi mtundu wa gaskets wachitsulo wopangidwa kuchokera kuzitsulo ndi mizere ya graphite.Amalukidwa kuchokera kuzitsulo zopyapyala zooneka ngati V kapena W-zoboola pakati.Ndi ntchito zambiri zosindikizira ndi kudzilimbitsa, sizikhala pachiwopsezo cha zolakwika za flange zomwe zimapanikizidwa pamalo osindikizira, ndipo si NaCl flange yosindikiza pamwamba;ndizosavuta kusweka, ndipo zimatha kuthetsa pang'ono mphamvu ya kukakamizidwa, kusintha kwa kutentha ndi kugwedezeka kwamakina;Itha kugwiritsidwa ntchito pakutentha kwambiri komanso kutentha pang'ono Imasunga magwiridwe antchito abwino kwambiri osindikizira pansi pazovuta zosiyanasiyana pamalumikizidwe ozungulira monga, vacuum yayikulu, kugwedezeka ndi kugwedezeka.The zitsulo graphite nsalu gasket ndi oyenera kutentha, ndi kusinthasinthagraphitelamba ndi oyenera kutentha -196 ~ 650°C (osachepera 450°C mu hydrolysis sing'anga)
