Zvemidziyo isiri-yesimbi yakadai segirazi, ceramics, graphite, mapurasitiki, nezvimwewo, ine zvinoshamisa maitiro.Inogona kubhadhara uye kuenzanisa zvikanganiso zvinokonzerwa nekuremara, mechanical processing, rigid deformation, kuisa misalignment, nezvimwewo, kuyera kusaenzana preload simba, uye kugadzirisa zvinobudirira matambudziko ekudonha kwezvivakwa zvakasiyana pasi pemamiriro akaoma.
Mhando dzePTFE gaskets
1. Yakachena PTFE gasket
Akachena PTFE gaskets ari flat gaskets, V-shaped gaskets, piston rings, bhora vharafu gaskets, nezvimwewo, ayo anoshandurwa nemichina kana kutemwa kubva.PTFE tsvimbo, PTFE chubhu,uyePTFE peji, iyo isingadziviriri, inodzivirira kuchembera, uye isingaite.Hunhu hwakanaka.Inogona kuva nesimba rakanaka remuchina pakati -100°C ne100°C.
Chimwe chinhu chechigadzirwa ichi ndechekuti chakachena.Kune zvimwe zvinhu zvinogona kusangana nazvo, yakachena PTFE gaskets haizokonzerese chero kusvibiswa kwavari.Kubatsira uku kunoita kuti ishandiswe zvakanyanya mukudya nemushonga.
2. Yakashandurwa PTFE gasket
Iyi mhando yePTFE gasket inosanganisira mapoka maviri, graphite yakazadzwa uye girazi fiber-yakazadzwa.
Graphite-yakazadzwa tetrafluoroethylene gasket ndeye PTFE ine graphite sekuzadza kweunifomu yakazara musanganiswa uyezve kupisa-tembiricha.Iyi PTFE gasket ine yakanaka yekuisa chisimbiso uye compressibility.
Girazi faibha-akazadzwa PTFE gaskets anoshandisa girazi faibha sekuzadza.Ichi chinyorwa chine zvinhu zvakanaka zvekudzoreredza uye zviri nani pane zvechinyakare zvinhu mukuita.Izvo zviri zviviri zvisingapfeke uye zvinodzivirira makemikari uye zvakanyatsokodzera mapepa uye maindasitiri ezvekudya.
3. Yakawedzerwa PTFE Gasket
Akawedzera PTFE gaskets anogona kuramba kutonhora kuyerera uye zvinokambaira, uye kuva nemukana wekuve nyore kuisa, kunyanya kugona kushingirira tembiricha yakaderera.Kuiswa chisimbiso kwechinhu ichi kwakavimbika kwazvo, uye zvakare kunopesana nekuputika.Inonyanya kukodzera nzvimbo dzakaoma.
8 zvakanakira zvePTFE gasket
1. Iyo PTFE gasket pachayo ine high corrosion resistance, yakagadzikana kushanda kwemuviri, yakakwirira uye yakaderera-kupisa kupikisa, uye inozadzisa kushanda kwayo kwakanaka kwekuvhara.Nekushandura simba rekumanikidzika rebhanhire resimbi rakasungirirwa, kuwanda (kuoma) kwegasket yakasungirirwa kunogona kuchinjwa kuti isangane nezvinodiwa zvakasiyana-siyana zvekushandisa.Inoshandiswa zvakanyanya mu petrochemical, michina, simba remagetsi, simbi, kuvaka ngarava, mushonga, atomic simba, uye maindasitiri emuchadenga.
2. PTFE gaskets inoshingirira mamiriro ekunze, uye PTFE ine hupenyu hwekuchembera hwakanakisa pakati pemapurasitiki.Iyo PTFE gasket pachayo ine yakakwirira corrosion resistance, yakagadzikana kushanda kwemuviri, yakakwirira uye yakaderera-yekushisa kuramba, uye yakawana yakanaka yekuisa chisimbiso kuita.Inoshandiswa zvakanyanya mu petroleum, makemikari, mishonga, magetsi emagetsi, uye maindasitiri esimbi.
3. Iyo PTFE gasket haina kuomerera.PTFE ine diki diki tension pakati pezvinhu zvakasimba uye hainamati kune chero zvinhu.
4. PTFE gaskets inoshingirira kune yakaderera tembiricha uye vane yakanaka michina kuoma;kunyangwe tembiricha ikadonha kusvika -196 ° C, vanogona kuchengetedza 5% kureba.Inokodzera kuisa chisimbiso zvikamu apo tembiricha uye kumanikidza kunochinja zvakanyanya.Icho chinhu chakamira chekuisa chisimbiso chekubatanidza flange senge pombi, mavharuvhu, pombi, zvinopisa kupisa, shongwe, manholes, uye maburi emaoko.
5. Mabasa uye zvakanakira zvePTFE gaskets ndeaya anotevera.Iyo yakakodzera svikiro inosanganisira angangoita ese emakemikari zvikamu zvakaita semvura, mafuta, acid solution, alkali solution, nezvimwe.
6. PTFE gasket is non-chepfu uye PTFE is physiologically inert, uye haina adverted reactions setsinga dzeropa dzakagadzirwa uye nhengo dzakaiswa mumuviri kwenguva yakareba.
7. PTFE gaskets inopesana nekuora, iinert kune akawanda makemikari uye zvinonyungudutsa, uye inogona kumira yakasimba acids uye alkalis, mvura uye zvakasiyana-siyana zvinonyungudutsa.Iyi gasket ine yakanaka kudzvanya uye kusimba kuita, akawanda-channel chisimbiso, uye imwe yekuzvisimbisa-inoshanda, iyo inogona kubvisa pesvedzero yekumanikidza, shanduko yetembiricha, uye mechanical vibration.
8. Pasi petembiricha yakakwira, tembiricha yakaderera, vacuum yakakwira, kuzununguka kwekuvhunduka, uye dzimwe shanduko dzema cyclical uye nemamiriro ezvinhu akaomarara, chengetedza kuita kwayo kwechisimbiso kwakanakisa.Nekuchinja kusanganiswa kwezvinhu zvegasket, dambudziko rekukukurwa kwemakemikari egasket neakasiyana midhiya rinogona kugadziriswa.Iyo flange yepamusoro haina kusungirirwa, iyo inobatsira kuchengetedza uye kutsiva.
9. PTFE gaskets inopesana nekupisa kwepamusoro, uye PTFE inogona kushandiswa pakushanda kwekushanda kwe250 ° C.
Ndezvipi zvinhu zvinofanirwa kutariswa pakusarudza PTFE gaskets
PTFE gaskets anoshandiswa mumhando dzakawanda dzemidziyo.Kuti uve nechokwadi chekuita kwakanaka, zvinhu zvinofanirwa kutariswa mukusarudzwa kwePTFE gaskets ndeaya anotevera:
1. Pakati: Mubvunzo wesvikiro uri nyore.Kungoda kuteerera mimwe mibvunzo midiki yakakosha, senge metallurgical work cylinders inowanzo shandisa mvura-glycol uye phosphate ester hydraulic oil.
2. Tembiricha: Iyo inodzivirira kutonhora NBR inofanirwa kutariswa kana tembiricha iri 20～-40℃.Izvo zvakajairika zveNBR zvinhu zvinoomesa zvinhu pasi penzvimbo yakaderera-tembiricha, zvichikonzera kuvuza.
3. Impact pressure: Kana michina yekuvaka yatangwa uye yakavharwa, kudzvanywa kwayo kunenge kwakakura kudarika kudzvanywa kwekushanda, saka inowanzoshandiswa sechisimbiso chikuru chine simba rekudzivirira uye kusvina gap HBY kana SPGW ine simba rekudzivirira. kusvika ku70MPA.
