Mefuta ea li-gaskets tsa PTFE
1. E hloekileng PTFE gasket
Li-gaskets tse hloekileng tsa PTFE ke li-gaskets tse bataletseng, li-gaskets tse bōpehileng joaloka V, mehele ea piston, li-gaskets tsa ball valve, joalo-joalo, tse fetotsoeng kapa tse khaotsoeng ka mochine.PTFE thupa, PTFE tube, leLetlapa la PTFE, e thibelang ho bola, e thibelang botsofali, le e sa tsitsang.Litšobotsi tse ntle.E ka ba le matla a matle a motjhini pakeng tsa -100°C le 100°C.
Tšobotsi e 'ngoe ea sehlahisoa sena ke hore se hloekile.Bakeng sa lintho tse ling tse ka kopanang le eona, li-gaskets tse hloekileng tsa PTFE li ke ke tsa baka tšilafalo leha e le efe ho tsona.Molemo ona o etsa hore e sebelisoe haholo lijong le meriana.
2. Fetotse PTFE gasket
Mofuta ona oa PTFE gasket o kenyelletsa mekhahlelo e 'meli, e tletseng graphite le fiber e tletseng khalase.
Tetrafluoroethylene gasket e tletseng graphite ke PTFE e nang le graphite e le setlatsi sa ho kopanya junifomo e feletseng le ho thunya ho matla a mocheso.Gasket ena ea PTFE e na le tiiso e ntle haholo le ho hatelloa.
Li-gaskets tsa PTFE tse tlatsitsoeng ka khalase li sebelisa fiber ea khalase joalo ka se tlatsang.Boitsebiso bona bo na le thepa e ntle ea ho hlaphoheloa 'me e molemo ho feta lisebelisoa tsa setso ts'ebetsong.Ka bobeli ha e sebetse ebile ha e na lik'hemik'hale 'me e loketse haholo indastering ea pampiri le ea lijo.
3. E atolositsoeng PTFE Gasket
E atolositsoeng PTFE gaskets ka hanela phallo e batang le creep, 'me ba le monyetla oa ho ba bonolo ho kenya, haholo-holo le matla a ho mamella ultra-tlase mocheso.Ts'ebetso ea ho tiisa ea thepa ena e ka tšeptjoa haholo, hape e hanyetsana le ho phatloha.E loketse ka ho khetheha bakeng sa libaka tse thata.
8 melemo ea PTFE gasket
1. PTFE gasket ka boeona e na le khanyetso e phahameng ea kutu, ts'ebetso e tsitsitseng ea 'mele, ho hanyetsa mocheso o phahameng le o tlaase,' me e finyella ts'ebetso ea eona e ntle ea ho tiisa.Ka ho fetola matla a tsitsipano a lebanta la tšepe le ts'oaretsoeng, boima (bothata) ba gasket e kentsoeng bo ka fetoloa ho finyella litlhoko tsa likopo tse sa tšoaneng.E sebelisoa haholo ho petrochemical, mechini, matla a motlakase, metallurgy, kaho ea likepe, meriana, matla a athomo le indasteri ea sefofane.
2. PTFE gaskets ke meteo-manganga, 'me PTFE na le molemo ka ho fetisisa botsofali bophelo har'a polasetiki.PTFE gasket ka boeona e na le khanyetso e phahameng ea kutu, ts'ebetso e tsitsitseng ea 'mele, ho hanyetsa mocheso o phahameng le o tlaase,' me e fihletse ts'ebetso e ntle ea ho tiisa.E sebelisoa haholo indastering ea peterole, ea lik'hemik'hale, ea meriana, ea motlakase le ea tšepe.
3. The PTFE gasket ha e khomarela.PTFE e na le tsitsipano e nyane ea holim'a metsi har'a lisebelisoa tse tiileng 'me ha e khomarele lintho leha e le life.
4. PTFE gaskets ba manganga ho mocheso tlaase 'me ba le molemo mechine toughness;le haeba mocheso o theohela ho -196 ° C, li ka boloka bolelele ba 5%.E loketse likarolo tsa ho tiisa moo mocheso le khatello li fetohang haholo.Ke ntho e tiileng ea ho tiisa bakeng sa likhokahano tsa flange joalo ka liphaephe, li-valve, lipompo, li-heaters tsa mocheso, litora, likoti le masoba a matsoho.
5. Mesebetsi le melemo ea PTFE gaskets ke tse latelang.Mokhoa o loketseng o kenyelletsa hoo e batlang e le likarolo tsohle tsa lik'hemik'hale tse kang metsi, oli, tharollo ea asiti, tharollo ea alkali, joalo-joalo.
6. PTFE gasket ha e chefo 'me PTFE e physiologically inert,' me ha e na le liphello tse mpe joaloka methapo ea mali ea maiketsetso le litho tse kenngoeng 'meleng ka nako e telele.
7. PTFE gaskets manganga ho kutu, ke inert ho ho fetisisa lik'hemik'hale le solvents, 'me ka mamella acid e matla le alkalis, metsi le tse fapa-fapaneng solvents manyolo.Gasket ena e na le ts'ebetso e ntle ea ho hatella le ho mamella, ho tiisa liteishene tse ngata, le ts'ebetso e itseng ea ho itlama, e ka felisang tšusumetso ea khatello, liphetoho tsa mocheso le ho sisinyeha ha mochini.
8. Tlas'a mocheso o phahameng, mocheso o tlase, vacuum e phahameng, ho sisinyeha ha maikutlo, le liphetoho tse ling tsa cyclical le maemo a fapaneng a thata, li boloka ts'ebetso ea eona e ntle ea ho tiisa.Ka ho fetola motsoako oa thepa ea gasket, bothata ba khoholeho ea lik'hemik'hale ea gasket ka mecha ea litaba e fapaneng bo ka rarolloa.Sebaka sa flange ha se kopane, se nolofalletsang tlhokomelo le ho nkeloa sebaka.
9. PTFE gaskets ba manganga ho mocheso phahameng, 'me PTFE ka sebelisoa ka ho sebetsa mocheso oa 250°C.
Ke lintlha life tse lokelang ho nahanoa ha u khetha li-gaskets tsa PTFE
PTFE gaskets sebelisoa ka mefuta e mengata ea thepa.Bakeng sa ho netefatsa ts'ebetso e ntle, lintlha tse lokelang ho nahanoa ha ho khethoa likhase tsa PTFE ke tse latelang:
1. Mahareng: Potso ea seaplane e batla e le bonolo.Feela lokela ho ela hloko ba bang ba khethehileng lipotso tse nyenyane, tse kang metallurgical mosebetsi disilindara hangata sebelisa metsi-glycol le phosphate ester haeteroliki oli.
2. Mocheso: Thempereichara e hanyetsanang le serame e lokela ho nkoa ha mocheso o le 20～-40℃.Thepa e akaretsang ea NBR e tla thatafatsa thepa tlas'a tikoloho ea mocheso o tlase, e leng se bakang ho lutla.
3. Khatello ea tšusumetso: Ha mechine ea kaho e qalisoa le ho koaloa, khatello ea eona ea ts'ebetso e kholo haholo ho feta khatello e tloaelehileng ea ho sebetsa, kahoo hangata e sebelisoa e le tiiso e kholo e nang le ts'ebetso ea ho hanyetsa le ho penya lekhalo la HBY kapa SPGW ka ho hanyetsa khatello ea maikutlo. ho fihlela ho 70MPA.
