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.
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%

Nuquladayada 'EPDM + PTFE' Laqabsashada giraanta xijaabka ah waxay ka dhigeysaa mid ku habboon in lagu isticmaalo sareeya - xaaladaha heerkulka, halkaasoo ashyaafyada xidhiidhka ah. Waxaa laga heli karaa cabirrada DN50 illaa DN600, oo siddooyinkeenna shaabadaysan ayaa la jaan qaada noocyo noocyo ah oo tuubbooyin ah oo ay ku jiraan xargaha xargaha leh tuubbooyinka jilicsan ee xargaha jilicsan ee xargaha leh. Tayada aan kala go 'lahayn ee kuraasta' EPDM + PTFE 'ee kuraasta cagta cagta cagta cagta cagta cagta ah ayaa ka imanaya hanaanka wax soo saar ee adag, kabaallaynta ugu dambeysay sayniska ee loo soo gudbiyo shey aan la kulmin oo keliya oo aan la kulmin laakiin ay dhaafto heerarka warshadaha oo keliya. Giraantani xidhashada waxay ku helaan adeegsi ballaaran dhammaan waaxaha kala duwan oo ay ka mid yihiin dharka, tareenka, kuleylka, dawada, ka-hortagga deegaanka, iyo ilaalinta deegaanka, ayaa u mahadceliya cimrigooda sare iyo dabacsanaantooda. Haddii aad wax ka qabanayso heerkulka sare ama walxaha wasakhaysan, siddooyinkeenna shaabadaha ayaa hubiya in tuubooyinkaagu si wanaagsan u shaqeeyaan, yareynta kharashaadka shaqada iyo dayactirka. Ku soo dhawow mustaqbalka Valve oo la jaan qaadaya saasnaastsine-ka Sanssheng + EPDM + PTFE isku-darka tuubbada tuubbada leh ee giraantaha ah - halkaas oo hal-abuurku la kulmo isku halaynta.
