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

Tilmaamaha waxaa loo habeeyey si ay u daboolaan baahiyaha warshado kala duwan. Iyada oo cabbirka dekedu u dhexeeyaan DN50 ilaa DN600, siddooyinkeena xidhidhisku waa kuwo ku filan in loo isticmaalo wax soo saarka dunta, saldhigyada tamarta, dhirta batroolka, nidaamyada HVAC, dawooyinka, dhisitaanka maraakiibta, biraha, iyo in ka badan. Nooca wafer-ka khadka dhexe ee jilicsan ee xidhidhiyaha balabaliga, oo ay ku jiraan ikhtiyaarada wafer wafer balanbaaliseed ee pneumatic, wuxuu bixiyaa is dhexgalka fudud iyo waafaqid labada isku xidhka wafer iyo flange. Kala duwanaanshiyahani wuxuu hubinayaa in fayadhowrkeena EPDM+PTFE isku dhafka balaaliyaha valve shaabadeynta si aan kala go 'lahayn loogu dhex dari karo nidaamyada jira, kor u qaadista waxtarka iyo cimri dhererka. Alaabtayadu waxay dhaafsiisan tahay shaqeynta kaliya si ay u muujiso mabaadi'da isku halaynta, hufnaanta, iyo hal-abuurka. Loogu talagalay codsiyada halka xaaladaha kulaylku ay ka jiraan, Sansheng Fluorine Plastics' giraanta xidhidhiyaha waxay u taagan tahay difaac ka dhanka ah caqabadaha ka imanaya bay'ada aadka u daran. Adiga oo dooranaya fayadhowrkayaga EPDM+PTFE iskudarka balaaliyaha valve xidhitaanka giraanta, maaha inaad dooranayso badeecad; waxa aad qaadanaysaa xal balan qaadaya in uu kor u qaadayo hufnaanta hawleed ee nidaamyadaaga, yaraynta kharashka dayactirka, iyo hubinta badbaadada iyo nadiifnimada hababkaaga.
