Madow/Cagaar PTFE/FPM + EPDM Rubber Valve Kursiga Kursiga Valve Balanbaalista
PTFE + EPDM kuraasta caagga ah ee la isku daray ee ay soo saartay SML ayaa si weyn loogu isticmaalaa dharka, xarunta korantada, petrochemical, kululaynta iyo qaboojiyaha, dawooyinka, dhismaha maraakiibta, birta, warshadaha iftiinka, ilaalinta deegaanka iyo meelaha 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 xirayo afkoda waalka iyo saxanka xiran.
Heerkulka: -10°C ilaa 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.
Heerkulka: -38°C ilaa +230°C.
Midabka: cad
Xadhkaha garaaca: 0%

Xulashadayada xirmooyinka xirmooyinka waxay ku habboon yihiin noocyo badan oo warbaahin ah, oo ay ku jiraan biyaha, saliidda, gaaska, saliidda saldhigga, iyo xitaa walxaha acidic ah ee gardarrada ah. Kala duwanaanshiyahani wuxuu hubinayaa, iyadoon loo eegin warshadahaaga ama dabeecadda gaarka ah ee warbaahintaada, shaabadeenna waxay ku siin karaan adkeysiga iyo cimri dhererka lagama maarmaanka u ah hawlgalka joogtada ah. Kala duwanaanshaha heerkulka hawlgalka ee alaabtayadu way u adkeysan karaan waa mid ballaaran, taasoo ka dhigaysa inay ku habboon yihiin codsiyada halka xaaladaha heerkulka sare ay ku badan yihiin. At Sansheng Fluorine Plastics, line-upka alaabtayada, oo ay ku jiraan nooca wafer-ka dhexe ee jilicsan shaabadeynta balabaliga valve iyo wafer wafer pneumatic, waxay xaqiijinaysaa u heellanaantayada hal-abuurnimada iyo wacnaanta. Iyada oo cabbirka dekeddu u dhaxayso DN50 ilaa DN600 iyo isku xirka la heli karo ee wafer iyo darafyada flange-ga labadaba, valvesyadayada waxaa loo qaabeeyey si loo hubiyo is-dhexgalka aan fiicnayn ee nidaamyadaada jira. Haddii aad u baahan tahay waalka balanbaalista, nooca lugaha oo labanlaab ah waalka balanbaalista badhkeed oo aan lahayn pin, ama qaabayn gaar ah oo kuraasta waalka ah, alaabtayada waxa loo dammaanad qaaday inay daboolaan baahiyahaaga si sax ah oo aan la barbar dhigi karin. Isku darka horumarsan ee Black/Green PTFE/FPM + EPDM Rubber Valve Kuraasta waxay muujinaysaa sida ay nooga go'an tahay bixinta qaybaha bixiya waxqabadka sare ee dharka, xarunta tamarta, batroolka, kuleylka iyo qaboojiyaha, dawooyinka, dhisitaanka maraakiibta, birta, warshadaha iftiinka, ilaalinta deegaanka, iyo qaybaha kale ee muhiimka ah.
