Graphite zvinhurudzi rutsva rwekuisa chisimbiso, uye irwo rudzi rwakakosha rwekuisa chisimbiso muindasitiri yemaindasitiri.Iyo ine yakanakisa corrosion resistance, yakakwirira uye yakaderera tembiricha kuramba, electromagnetic radiation kuramba, diki friction factor, self-lubrication, elasticity, uye yakaderera permeability kune zvinwiwa nemagasi.
Graphite gasketsinogona kukuyiwa kana kudhindwa kubva kumarata egraphite akachena kana simbi (mahwendefa emazino, mahwendefa akatsetseka, mambure) kuti awedzere kusimbisa mahwendefa egraphite maererano nemamiriro ekushanda akafanana.
1. Zvimiro zve flexible graphite gasket:
1. High-purity graphite ine yakanaka impermeability kune gasi uye mvura, yakadai sendiro yakaonda nehupamhi hwe 0.125mm, chiyero chehelium inongova 2 * 10-1cm3 / s.
2. Kudzivirira kwakanaka kwekushisa.Iyo tembiricha ye flexible graphite mune isiri-hydrolytic svikiro ndeye -200 ~ 600℃, asi zviri nyore kuve oxidized mune hydrolytic medium.
3. Anisotropy: Thermal conduction, conductivity yemagetsi uye kuwedzera coefficient ye flexible graphite ine anisotropy yakajeka.
4. Kuramba kwakasimba kweUV.
5. Good corrosion resistance, yakanaka kugadzikana kwemakemikari kune general chemical solvents, esters, water vapour, kuderedza midhiya, nezvimwewo.
Nekudaro, pane zvimwe zvipimo muiyo hydrolysis medium.
6. Low density, simba guru, kunaka kupfava uye kusimba.
Chiyero chekushandiswa kwe flexible graphite
Inoshandiswa mumaindasitiri pombi flanges, kupisa exchanger, mavharuvhu anovhara, condensers, mhepo amplifiers, exhaust pombi, mafiriji, nezvimwe.
Inoshanda svikiro: mvura, chiutsi, mafuta, asidhi, alkali, organic solvent, ammonia, hydrogen, nezvimwe.
2. Simbi isina tsvina inowedzera kusimbisa girafu gasket
Graphite yakakwirira-simba gaskets, inozivikanwawo se graphite inorganic gaskets, inogadzirwa kubva kune imwe yakasimbiswa graphite pepa mapepa mitsetse kana pasi.Iyo lining material inogona kunge yakafanana nesimbi sheet sezvinodiwa.Pamusana pesimba rakakwirira remagetsi ekugadzirisa magirafu emagetsi, akakodzera gaskets ane madhayamita maduku, uye kuwedzera kusimbiswa kwema graphite gaskets kunovandudza zvikuru simba remagetsi.Yakanakisa zvivakwa zvakaita semakemikari corrosion resistance, electromagnetic radiation resistance, yakakwirira/yakaderera tembiricha kuramba, uye hupenyu hurefu.
Zvimwe zvekuwedzera kune graphite gasket classification:
1. Carbon simbi inowedzera kusimbisa iyographite gasket: kuguma kwe flexible graphite sheet inosungirirwa ne carbon steel strip (0.2mm), uye ipapo pasi, iyo inosimbisa simba remagetsi.
2. 304 simbi isina tsvina inowedzera kusimbisa graphite gasket: flexible graphite flakes inonamirwa kumativi ose e304 stainless steel, iyo ine yakanyanyisa yakakwirira yemagetsi simba.Inokodzerawo hukuru hwakasiyana-siyana uye maumbirwo akaoma, uye zvakare iri nyore kutakura.Iyo zvakare inzvimbo yakakurumbira yekushandisa.Mhando yakawanda ye gaskets.
3. 316 simbi isina tsvina inowedzera kusimbisa iyo graphite gasket: ine yakanaka corrosion resistance uye yakakwirira tembiricha simba, asi mutengo wakadererawo pane zvimwe zvinhu.
3. Metal graphite yakarukwa kuita gasket
Metal-graphite woven gaskets imhando yemarata-inorganic gaskets akarukwa kubva kusimbi mitsetse uye graphite strips.Iwo akarukwa kubva kuV-akaumbwa kana W-akaita matete simbi mitsetse uye mafirita.Iine akawanda-channel yekuisa chisimbiso uye yekuzvisimbisa-inosimbisa mabasa, haisi panjodzi yekukanganisa kweflange yakatsikirirwa munzvimbo yekuisa chisimbiso, uye haisi NaCl flange sealing surface;iri nyore kubvisa, uye inogona kubvisa zvishoma pesvedzero yekumanikidza, kushanduka kwetembiricha uye kudengenyeka kwemagetsi;inogona kushandiswa pakupisa kwakanyanya uye yakaderera tembiricha Inochengetedza yakanakisa yekuisa chisimbiso pasi pemamiriro akasiyana-siyana akaomarara pamajoini ekutenderera akadai se, high vacuum, kuvhunduka uye vibration.Iyo simbi graphite yakarukwa gasket inokodzera tembiricha, uye inochinjikagraphitebhandi rakakodzera kutonhora -196 ~ 650°C (kwete pasi pe450°C mu hydrolysis medium)
