Kwizixhobo ezingezizo zetsimbi ezifana neglasi, iiseramiki, igraphite, iiplastiki, njl., zinempembelelo engaqhelekanga.Iyakwazi ukubuyisela kunye nokulinganisa iimpazamo ezibangelwa yiziphene, ukuqhutyelwa komatshini, ukuguqulwa okuqinileyo, ukulungelelaniswa kofakelo, njl., Ukulinganisela amandla okulayisha kwangaphambili, kunye nokusombulula ngokufanelekileyo iingxaki zokuvuza kwezibonelelo ezahlukeneyo phantsi kweemeko ezinzima.
Iindidi ze-PTFE gaskets
1. PTFE gasket ecocekileyo
Iigaskets ezicocekileyo ze-PTFE ziigaskets ezisicaba, iigaskets ezimile okwe-V, amakhonkco episton, iigaskets zevalve yebhola, njl.njl., ezijikwa ngoomatshini okanye zisikwe ukusuka.Intonga ye-PTFE, PTFE ityhubhu, kwayeIphepha le-PTFE, enganyangekiyo kwi-corrosion, anti-aging, kunye ne-non-conductive.Iimpawu ezilungileyo.Inokuba namandla omatshini alungileyo phakathi kwe -100°C kunye ne-100°C.
Olunye uphawu lwale mveliso kukuba icocekile.Kwezinye izinto ezinokudibana nayo, iigaskets ezinyulu ze-PTFE aziyi kubangela naluphi na ungcoliseko kuzo.Olu ncedo luyenza isetyenziswe kakhulu ekutyeni nakumayeza.
2. Modified PTFE gasket
Olu hlobo lwe-PTFE gasket lubandakanya iindidi ezimbini, igraphite ezaliswe kunye neglasi yefiber-ezaliswe.
I-graphite-ezaliswe yi-tetrafluoroethylene gasket yi-PTFE enegraphite njengesithako sokuxubana okupheleleyo kunye nobushushu obuphezulu bokudubula.Le gasket ye-PTFE inotywino oluhle kakhulu kunye noxinzelelo.
Iigaskiti ze-PTFE ezizaliswe yifayibha yeglasi zisebenzisa ifayibha yeglasi njengesihluzi.Esi sixhobo sineempawu ezintle zokubuyisela kwaye zingcono kunezixhobo zendabuko ekusebenzeni.Yomibini i-resistant-resistant kunye ne-chemical-resistant kwaye ifaneleke kakhulu kumashishini ephepha kunye nokutya.
3. Eyandisiweyo PTFE Gasket
I-PTFE gaskets eyandisiweyo inokuxhathisa ukuhamba okubandayo kunye nokuhamba, kwaye ibe nenzuzo yokuba lula ukuyifaka, ngokukodwa ukukwazi ukumelana nobushushu obuphantsi kakhulu.Ukusebenza kokutywinwa kwesi sixhobo kunokwethenjelwa kakhulu, kwaye kuchasene nokuqhuma.Ifaneleke ngakumbi iindawo ezirhabaxa.
8 iingenelo PTFE gasket
1. I-PTFE gasket ngokwayo inoxhathiso oluphezulu lwe-corrosion, umsebenzi ozinzileyo womzimba, ukuxhathisa okuphezulu kunye nobushushu obuphantsi, kwaye ifezekisa ukusebenza kwayo kakuhle kokutywinwa.Ngokutshintsha amandla oxinzelelo lwebhanti yensimbi edibeneyo, ubuninzi (ubunzima) be-gasket edibeneyo inokutshintshwa ukuze ihlangabezane neemfuno zezicelo ezahlukeneyo.Isetyenziswa kakhulu kwi-petrochemical, oomatshini, amandla ombane, isinyithi, ukwakha iinqanawa, amayeza, amandla e-atom, kunye namashishini e-aerospace.
2. Iigaskets ze-PTFE ziyakwazi ukumelana nemozulu, kwaye i-PTFE inobomi obungcono bokuguga phakathi kweeplastiki.I-PTFE gasket ngokwayo inokumelana ne-corrosion ephezulu, umsebenzi ozinzileyo womzimba, ukumelana nobushushu obuphezulu kunye nobushushu obuphantsi, kwaye ifezekise ukusebenza kakuhle kokutywinwa.Isetyenziswa kakhulu kwi-petroleum, iikhemikhali, amayeza, amandla ombane, kunye namashishini entsimbi.
3. I-PTFE gasket ayibambeleli.I-PTFE inoxinzelelo oluncinci lomphezulu phakathi kwemathiriyeli eqinileyo kwaye ayibambeleli kuyo nayiphi na into.
4. PTFE gaskets ukumelana amaqondo obushushu aphantsi kwaye unobulukhuni elungileyo koomatshini;nokuba iqondo lobushushu lehla ukuya kwi -196°C, banokugcina ubude be-5%.Kufanelekile kwiindawo zokutywinwa apho ubushushu kunye noxinzelelo lutshintsha kakhulu.Yinto yokutywina emileyo yoqhagamshelo lweflange olufana nemibhobho, iivalvu, iimpompo, izitshintshi zobushushu, iinqaba, imingxunya, kunye nemingxuma yezandla.
5. Imisebenzi kunye nezibonelelo ze-PTFE gaskets zimi ngolu hlobo lulandelayo.Indawo efanelekileyo ibandakanya phantse zonke iikhemikhali ezifana namanzi, ioli, isisombululo se-asidi, isisombululo sealkali, njl.
6. I-PTFE gasket ayinayo ityhefu kwaye i-PTFE ayisebenzi ngokwasemzimbeni, kwaye ayinazo iziphumo ezibi njengemithambo yegazi eyenziweyo kunye namalungu afakwe emzimbeni ixesha elide.
7. Iigaskets ze-PTFE ziyakwazi ukumelana nokuhlwa, azikwazi ukujongana neekhemikhali ezininzi kunye nezinyibilikisi, kwaye ziyakwazi ukumelana neeasidi ezinamandla kunye nealkalis, amanzi kunye nezinyibilikisi ezahlukeneyo zezinto eziphilayo.Le gasket inoxinzelelo oluhle kunye nokusebenza kokuqina, ukutywinwa kwamajelo amaninzi, kunye nomsebenzi othile wokuziqinisa, onokuphelisa impembelelo yoxinzelelo, utshintsho lobushushu kunye nokungcangcazela komatshini.
8. Phantsi kobushushu obuphezulu, ubushushu obuphantsi, ivacuum ephezulu, ukungcangcazela kwentshukumo, kunye nolunye utshintsho lwebhayisikile kunye neemeko ezahlukeneyo ezinzima, gcina ukusebenza kwayo okubalaseleyo kokutywinwa.Ngokutshintsha ukudibanisa kwezinto ze-gasket, ingxaki yokukhukuliseka kweekhemikhali kwi-gasket ngamajelo ahlukeneyo angasombululwa.Umphezulu we-flange awubophekanga, oququzelela ukugcinwa kunye nokutshintshwa.
9. PTFE gaskets ukumelana namaqondo obushushu aphezulu, kwaye PTFE ingasetyenziswa kwiqondo lobushushu ukusebenza 250°C.
Yeyiphi imiba ekufuneka iqwalaselwe xa ukhetha i-PTFE gaskets
Iigaskets ze-PTFE zisetyenziswa kwiintlobo ezininzi zezixhobo.Ukuze kuqinisekiswe ukusebenza kakuhle, imiba ekufuneka iqwalaselwe ekukhethweni kweegasket ze-PTFE zezi zilandelayo:
1. Phakathi: Umbuzo wesixhobo esiphakathi ulula noko.Kufuneka nje ingqalelo eminye imibuzo emincinci ekhethekileyo, njengeesilinda zomsebenzi we-metallurgical zihlala zisebenzisa amanzi-glycol kunye ne-phosphate ester hydraulic oil.
2. Ubushushu: I-NBR ekwaziyo ukumelana nokubanda kufuneka ithathelwe ingqalelo xa iqondo lobushushu liku-20～-40℃.Izinto eziqhelekileyo ze-NBR ziya kwenza lukhuni izinto phantsi kwendawo yobushushu obuphantsi, okubangela ukuvuza.
3. Uxinzelelo lwempembelelo: Xa umatshini wokwakha uqalwa kwaye uvaliwe, uxinzelelo lwalo lwempembelelo lukhulu kakhulu kunoxinzelelo oluqhelekileyo lokusebenza, ngoko ke luhlala lusetyenziswa njengetywina eliphambili kunye nokumelana nempembelelo kunye nokucudisa i-gap HBY okanye i-SPGW kunye nokuxhatshazwa koxinzelelo ukuya kuthi ga kwi-70MPA.
