Lisebelisoa tsa graphiteke mofuta o mocha oa thepa ea ho tiisa, hape ke mofuta oa bohlokoa oa thepa ea ho tiisa indastering ea indasteri.E na le khanyetso e ntle ea kutu, e hanyetsa mocheso o phahameng le o tlase, ho hanyetsa mahlaseli a motlakase, ntho e nyane ea likhohlano, ho itšehla thajana, elasticity, le ho kenella ka tlase ho metsi le likhase.
Li-gaskets tsa graphitee ka siloa kapa ea hatisoa ho tloha lipoleiti tse hloekileng tsa graphite kapa tšepe (lipoleiti tsa meno, lipoleiti tse bataletseng, matlooa) ho matlafatsa lipoleiti tsa graphite ho ea ka maemo a tšoanang a ho sebetsa.
1. Likarolo tsa flexible graphite gasket:
1. Graphite e hloekileng e na le ho se lekane hantle ho khase le mokelikeli, joalo ka poleiti e tšesaane e nang le botenya ba 0.125mm, tekanyo ea helium ke 2 * 10-1cm3 / s feela.
2. Ho hanyetsa mocheso o motle.Mocheso oa graphite e feto-fetohang sebakeng se seng sa hydrolytic ke -200 ~ 600℃, empa ho bonolo ho oxidized ka hydrolytic medium.
3. Anisotropy: Thermal conduction, conductivity ea motlakase le coefficient ea katoloso ea graphite e feto-fetohang e na le anisotropy e hlakileng.
4. Khanyetso e matla ea UV.
5. Ho hanyetsa kutu e ntle, botsitso bo botle ba lik'hemik'hale ho li-solvents tsa lik'hemik'hale tse akaretsang, li-esters, mouoane oa metsi, ho fokotsa mecha ea litaba, joalo-joalo.
Leha ho le joalo, ho na le mefokolo e itseng sebakeng sa hydrolysis.
6. Boima bo tlaase, matla a phahameng, bonolo bo botle le ho tiea.
Bophara ba tšebeliso ea graphite e feto-fetohang
E sebelisoa liphaepheng tsa liphaephe tsa indasteri, li-heaters tsa mocheso, likoahelo tsa valve, li-condensers, li-amplifiers tsa moea, liphaephe tsa ho qeta nako, lihatsetsi, joalo-joalo.
Mocheso o sebetsang: metsi, mouoane, oli, asiti, alkali, organic solvent, ammonia, hydrogen, joalo-joalo.
2. tšepe e sa hloekang ka ho eketsehileng e matlafatsa graphite gasket
Li-gaskets tsa graphite tse matla haholo, tse tsejoang hape ka hore ke li-graphite inorganic gaskets, li entsoe ka masela a pampiri a graphite a matlafalitsoeng kapa fatše.Thepa ea lesela e ka ba letlapa le tšoanang la tšepe kamoo ho hlokahalang.Ka lebaka la matla a phahameng a mechine ea likhase tsa graphite tse feto-fetohang, li loketse li-gaskets tse nang le li-diameter tse nyenyane, 'me ho matlafatsoa ka ho eketsehileng ha likhase tsa graphite ho ntlafatsa haholo matla a mochine.Thepa e ntle haholo joalo ka k'hemik'hale ea kutu ea lik'hemik'hale, khanyetso ea mahlaseli a motlakase, ho hanyetsa mocheso o phahameng / tlase, le bophelo bo bolelele.
Lintlafatso tse ling ho sehlopha sa graphite gasket:
1. Litšepe tsa carbon li matlafatsa ka ho eketsehilenggraphite gasket: qetellong ea letlapa le feto-fetohang la graphite le koaletsoe ka lesela la tšepe la carbon (0.2mm), ebe le fatše, le matlafatsang matla a mochine.
2. 304 tšepe e sa hloekang e boetse e matlafatsa graphite gasket: li-flakes tse tenyetsehang tsa graphite li khomaretsoe mahlakoreng ka bobeli a tšepe e sa hloekang ea 304, e nang le matla a holimo haholo a mochine.E boetse e loketse mefuta e fapaneng ea boholo bo boholo le libopeho tse rarahaneng, hape e bonolo ho e tsamaisa.Hape ke sebaka se tsebahalang haholo sa likopo.Mefuta e mengata ea li-gaskets.
3. 316 tšepe e sa hloekang e matlafatsa le ho feta graphite gasket: e na le khanyetso e ntle ea kutu le matla a phahameng a mocheso, empa litšenyehelo li boetse li tlaase ho feta lisebelisoa tse ling.
3. Metal graphite e lohelletsoeng ka gasket
Metal-graphite loven gaskets ke mofuta oa tšepe-inorganic gaskets e lohiloeng ka likhoele tsa tšepe le likhoele tsa graphite.Li lohiloe ka likhoele tse tšesaane tse nang le sebopeho sa V kapa sa W, le li-filler.Ka mesebetsi e mengata ea ho tiisa le ho ikemela, ha e kotsing ea liphoso tsa flange e hatelitsoeng ka holim'a ho tiisa, 'me ha se NaCl flange ho tiisa holim'a metsi;ho bonolo ho qhaqha, 'me e ka felisa ka mokhoa o itseng tšusumetso ea khatello, phetoho ea mocheso le ho sisinyeha ha mechine;e ka sebelisoa ka mocheso o phahameng le mocheso o tlase E boloka ts'ebetso e babatsehang ea ho tiisa tlas'a maemo a sa tšoaneng a thata ka har'a manonyeletso a potoloho a kang , vacuum e phahameng, ho tšoha le ho sisinyeha.The tšepe graphite lohiloeng gasket ke a loketse bakeng sa mocheso, le tenyetsehanggraphitelebanta le loketse mocheso -196~650°C (e seng ka tlase ho 450°C sebakeng sa hydrolysis)
