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%

Codsiga shaabadihiin waxay ka kooban yihiin jawi kala duwan, oo ay ku jiraan laakiin aan ku xaddidnayn, biyaha, saliidda, gaaska, saliidaha saldhigga ah, iyo asiidhyada, oo muujinaya wax-ku-noqoshadooda aan isbarbar dhigin. Loogu talagalay in lagu daboolo cabbirro badan oo deked ah oo ka bilaabma DN50 ilaa DN600, giraanta xidhida balaalista ee Teflon waxay hubisaa taam ahaanshaha aan fiicnayn iyo waxqabadka heersare Kor u qaadista rafcaankeeda ayaa ah khadka dhexe ee nooca wafer-ka jilicsan ee xidhidhiyaha balabaliga oo ay weheliso maraqa pneumatic Balanbaalista valve, labadaba si xariif ah ayaa loogu talagalay in lagu bixiyo xiriir adag iyada oo loo marayo wafer ama geesaha. Habkan cusubi ma fududa oo kaliya habka rakibidda laakiin sidoo kale wuxuu si weyn u wanaajiyaa waxqabadka waalka isagoo hubinaya inuu dillaaco Kala duwanaanshiyaha ayaa ku fidsan la jaanqaadkiisa balaaliyeyaasha balabaalista, oo ay ku jiraan nooca lugaha labajibbaaran baalbaalle badhkeed oo aan lahayn biin, oo daboolaya baahiyo ballaadhan oo warshadeed. Iyada oo fiiro gaar ah loo leeyahay tafatirka iyo raadinta tayada aan joogsiga lahayn, giraanta xidhitaanka balaaliska ee Teflon ee SanSheng Fluorine Plastics waxay u taagan tahay tilmaan isku halaynta iyo hufnaanta muuqaalka warshadaha ee adag.
