Eber Leakage PTFE Valve Kursiga Balanbaalista Valve Qaybaha DN50 - DN600
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 kuleyl iyo koronto oo aad u wanaagsan. 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%
Halbeegga Shaxda:

Rabadhka Nitrile wuxuu leeyahay is-fidin wanaagsan, sifooyin fidineed, caabbinta abrasion iyo hydrocarbon-astayaal adkaysi u leh. Waxaa loo isticmaali karaa sida walxaha guud ee biyaha, faakuum, acid, milix, alkali, dufan, saliid, subag, saliid hydraulic, glycol, iwm. Looma isticmaali karo meelaha sida acetone, ketone, nitrate, iyo hydrocarbons fluorinated. |

Faa'iidooyinka:
PTFE waxay u taagan tahay PolyTetraFluoroEthylene, oo ah ereyga kiimikaad ee polymer (CF2) n.
Polytetrafluoroethylene (PTFE) waa unug heerkulbeeg ah oo ka tirsan qoyska fluoropolymer ee balaastikada waxayna leedahay iskudhaf hoose oo isjiidjiid ah, sifooyin dahaadh aad u fiican.
PTFE waa mid kiimiko ahaan aan firfircoonayn walxaha badankood. Waxa kale oo ay u adkeysan kartaa codsiyada kulaylka badan waxayna si fiican u taqaanaa waxyaabaha ka hortagga -
Doorashada qalabka giraanta kursiga saxda ah ayaa badanaa ah go'aanka ugu adag Ball Valve Xulashada. Si loo caawiyo macaamiisheena inta lagu jiro nidaamkan, waxaan diyaar u nahay inaan bixino macluumaadka ku saabsan codsiga macaamiisha.
Kuraasta waalka PTFE ee ay soo saartay US ayaa si weyn loogu isticmaalaa dharka, saldhiga tamarta, petrochemical, kulaylinta iyo qaboojiyaha, dawooyinka, dhismaha maraakiibta, biraha, warshadaha iftiinka, ilaalinta deegaanka, Warshadaha Warqadaha, Warshadaha Sonkorta, Hawada Culayska 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.
