The raw materials ofPTFE gasketsvane yavo inowanika tembiricha uye kushanda kumanikidzwa siyana ukoshi.Mazhinji gaskets haagone kushandiswa kune yakakwira tembiricha uye yakakwirira kushanda kumanikidza.Paunenge uchisarudza gasket, inofanira kutanga yagamuchirwa maererano nekushisa kwekushanda kwe gasket, chaiyo yekushanda kushandiswa, uye Pr kukosha.
The raw materials ofPTFE gasketsvane yavo inowanika tembiricha uye kushanda kumanikidzwa siyana ukoshi.Mazhinji gaskets haagone kushandiswa kune yakakwira tembiricha uye yakakwirira kushanda kumanikidza.Paunenge uchisarudza gasket, inofanira kutanga yagamuchirwa maererano nekushisa kwekushanda kwe gasket, chaiyo yekushanda kushandiswa, uye Pr kukosha.
Izvo zvigadzirwa zvePTFE gaskets zvinofanirwa kushingirira mukuora kwemakemikari uye corrosion yemuviri.Akakodzera gaskets anofanirwa kushandiswa zvinoenderana neayo chaiwo ekushandisa zvinhu mhando uye corrosion hunhu, uye ipapo iyo hydrodynamic corrosion resistance ye gasket raw materials inofanirwa kutariswa.Iyo hydrodynamic corrosion kuramba inoratidzirwa nekuwedzera kwehuremu uye huremu hwemambure egasket zvinhu mushure mekupinda kwemvura.Kune gaskets inobata zvisiri zvepurasitiki zvinhu, kuchengetedza kwakaringana ukobvu kuwedzera mwero wezvigadzirwa zvegasket kunobatsira pakuvandudza kwekuisa chisimbiso pasi pechikonzero chekuvimbisa zvimwe zvivakwa.
Iyo inokambaira yekuzorora mwero wePTFE gasket ndiyo yakakosha paramende yemhando yekuongorora kwekuita kweiyo gasket zvinhu.Iyo inoratidza kugona kweiyo gasket zvinhu kuramba kuzorora kwekushushikana uye kukambaira deformation.general.Iyo diki iyo creep relaxation ratio, iyo yakakura kushushikana kwemukati panguva yebasa.Iyo iri nani yekuisa chisimbiso ndeye asiri-asbestos gaskets.Kutamba kuzorora ndicho chikonzero chakakosha chekudonha kwe looper flange panguva yekushanda.Inotamba mhedzisiro yekuita sarudzo pahupenyu hwesevhisi yekubatanidza.Iyo shrinkage performance yePTFE gasket inoratidza iyo ductility kana purasitiki deformation ye gasket pasi pekuita kwechinguva chidiki.Kugadzirisa kukanganisa kwakasiyana-siyana kwepamusoro peflange.Zvakare, kuita kwekudzivirira kudonha.
Kazhinji kutaura, kuderera kwekuita kweasiri-asbestos gaskets kunogona kutariswa sekuisa chisimbiso mirau.Kuenzaniswa nekuwedzera, iyo resilience performance ndiyo inonyanya kukosha index kukosha.Iyo resilience performance inoreva kubhadharwa kweiyo gasket, iyo inogona kutevera kupatsanurwa kweflange nekuda kwekupisa kana mekiniki michina mutoro kuchengetedza chisimbiso.Kuita kwePTFE gasket ndiko kuita kwakadzama kwemhando ye gasket, uye chiyero chekuvuza indekisi yekuona kukosha.Zvichienderana neiyo leak rate index kukosha, kugona kuvhara kwegasket kunogona kuongororwa uye kuenzaniswa.Iyo leakage rate ndiyo yakakosha parameter iyo inofanirwa kutariswa pakusarudza gaskets.
4 Zvinhu Zvinoda Kunetseka Kana Kuisa PTFE Gaskets
1. Mutsara wekuisa chisimbiso kana nzvimbo yakasimudzwa yePTFE gasket seal haifaniri kukuvara.Iyo PTFE gasket chisimbiso muchirongwa chekutarisa inogona kushandisa kuruboshwe uye kurudyi mukati maburi.Kuiswa chisimbiso kwePTFE gasket chisimbiso che hydraulic muchina inonyanya kuenderana neshaft kana gomba.Mutsara wemuromo wakanyatsoenderana unofanirwa kuve wakangwarira mukuita kwese kwekuisa, kutakura, uye kuchengetedza.Ichi chikamu chinogadzirwa neyakapfava uye inoshingirira yakakwirira-kuchena graphite, kemikari fiber, rabha, uye plastiki inoshingirira mukuora, kupisa kwakanyanya uye kuchembera.Insulation board uye zvimwe zvinhu zvakadaro zvisina njodzi zvinoumbwa nezvinhu, saka kana zvangokuvadzwa, zvinokonzeresa njodzi huru yakavanzika kune chikamu chekuisa chisimbiso.
2. Pakuisa PTFE gasket seals, tinofanira kungwarira zvikuru, uye nzira yekuisa inofanira kuitwa zvishoma nezvishoma.Munguva yese yekuisa maitiro, usamanikidza kuisirwa neyakakura yakawandisa chimiro, izvo zvichaita kuti munhu wese PTFE gasket zvisimbiso.Iyo yekutanga prefabricated component structure yakaparadzwa.
3. Kuiswa kwePTFE gasket seals kunofanirwa kuenderana nekuenzanisa uye kuenzanisa.Paunenge uchiisa, isa iyo PTFE gasket chisimbiso pachinzvimbo cheiyo yakanamatira muromo wepamusoro (kana inonzwisisika yakasimudzwa pamusoro) kudzivirira system software kushanda Panguva yese yemaitiro, nekuda kwekuchinja (semuenzaniso, kuwedzera) kwemamiriro ayo ekushanda, kutadza kwakakonzera. ne micro-leakage yakaitika.Izvo zvinodiwa kuti urambe uchitarisa uye kuita basa rakanaka munhanho inotevera yePTFE gasket chisimbiso.
4. Iyo PTFE gasket ine hunyanzvi hwekuita, kupisa kupisa, kushomeka kwekusagadzikana, kusagadzika, kuzvigadzika, kuita kwemagetsi emagetsi, uye kushomeka kwakanyanya.
Sezvigadzirwa zverabha, zvakagadziridzwa PTFE gaskets zvinogona kuitwa polytetrafluoroethylene pombi, tsvimbo, mabhandi, ndiro, epurasitiki mafirimu, etc. Anowanzo shandiswa pakuora-resistant pombi, midziyo, pombi, mavharuvhu uye Kudzora radar kuona, high-frequency kutaurirana. midziyo, wireless communication equipment, etc.
Ese mafirita anogona kutakura tembiricha yekuverengera yePTFE anowedzerwa kune yakagadziridzwa tetrafluoroethylene gasket.Mhando dzemafirita dzinosanganisira girazi faibha, simbi zvinhu, metalized simbi oxides, yakakwira-kuchena graphite, molybdenum disulfide, kabhoni fiber nyoro, Polyimide firimu, nezvimwewo, mashandiro ayo emuchina anogona kuvandudzwa zvikuru.Uye zvakare, zvimwe zvivakwa zvePTFE zvinogona kuchengetedzwa, uye kupfeka kuramba uye kukosha kwePV kunogona kuwedzerwa ne1000 nguva.
