Madow/Cagaar PTFE/FPM + EPDM Rubber Valve Kursiga Kursiga Valve Balanbaalista
PTFE + EPDM Kuraasta caagga ah ee isku dhafan ee ay soo saarto SML ayaa si weyn loogu isticmaalaa dharka, xarunta korontada, petrochemical, kululaynta iyo qaboojiyaha, dawooyinka, dhismaha maraakiibta, birta, warshadaha iftiinka, ilaalinta deegaanka iyo meelo kale.
Waxqabadka badeecada: caabbinta heerkulka sare, caabbinta acid wanaagsan iyo alkali iyo caabbinta saliidda; leh adkeysi soo kabasho wanaagsan leh, adag oo waara iyada oo aan dareerin.
PTFE+EPDM
Xadhkaha Teflon (PTFE) waxa uu dulsaaraa EPDM kaas oo ku xidhan giraan adag oo phenolic ah oo ku yaala wareegga kursiga ee dibadda. PTFE waxay ku fidsan tahay wejiyada kursiga iyo bannaankaba dhexroorka shaabadda flange, oo si buuxda u daboolaya lakabka elastomer-ka ee EPDM ee kursiga, kaas oo siiya adkeysi loogu talagalay xiridda afkoda waalka iyo saxanka xiran.
Xaddiga heerkulka: - 10 ° C illaa 150 ° C.
Budada PTFE (Polytetrafluoroethylene)
PTFE (Teflon) waa polymer-ka ku salaysan fluorocarbon oo caadiyan ah kan ugu adkaysiga badan kiimikaad ee balaastikada oo dhan, iyadoo ilaalinaysa sifooyin heer sare ah oo kuleyl iyo koronto ah. PTFE sidoo kale waxay leedahay iskudhaf hoose oo is jiid jiid ah sidaa darteed waxay ku habboon tahay codsiyo badan oo qulqulka hooseeya.
Walaxdani maaha -wax wasakhaysan oo ay aqbasho FDA ee codsiyada cuntada. Inkasta oo sifooyinka farsamada ee PTFE ay hooseeyaan, marka la barbardhigo balaastikada kale ee la farsameeyey, hantidoodu waxay ahaanayaan kuwo faa'iido leh oo ka badan heerkul ballaaran.
XUQUUQDA QARANKA: - 38 ° C illaa + 230 ° C.
Midabka: cad
Xadhkaha garaaca: 0%

Keydka furaneffly valve the the the the the linging grobiing si sahlan looga soo horjeeday injineerku ka soo baxo PTFE iyo EPDM. Isku-darkan ma aha oo kaliya waxay xaqiijineysaa adkeysiga aan tooska ahayn ee ka dhanka ah heerkulka sareeya laakiin sidoo kale waxay bixisaa is-waafajin gaar ah oo leh noocyo warbaahineed oo ballaaran. Haddii ay tahay baahida adag ee geedka patrochemical of patchemical, saxsanaanta loo baahan yahay dawooyinka, ama adkaanta looga baahan yahay warshadaha macdanta, oo siddooyinkiisa xirashada waxay u taagan yihiin xakameynta dareeraha ee dareeraha. Waxaa loogu talagalay inay si aan kala go 'lahayn ula jaanqaada xiriirinta xabaasha ah ee xabaashka ah, oo ah xargahaan xarkaha ah ee ka yimaada DN650 illaa DN600 Naqshadooda sare waxaa lagu dhameystiraa fududeynta is dhexgalka nooca lugta lugta badhkeed ee labajibbaaranaha alwaaxyada oo aan lahayn biin, oo ay ku xalliyaan injineernimada iyo xirfadlayaal raadinaya isku kalsooni la'aan iyada oo aan laheyn isku hallayn la'aan. Wixii ka baxsan mudnaantooda farsamo, PTFE / FPM + FPM + EPDM Ring Palve waxay ku jirtaa cimri dherer iyo isku haleeya xaaladaha sahlan -
