Cabbirka Midabka Gaarka ah ee PTFE Washer
Faahfaahin
PTFE giraanta polytetrafluoroethylene waa mid ka mid ah walxaha iska caabinta daxalka wanaagsan ee adduunka maanta, markaa hel sumcadda "boqor caag ah". Waxaa lagu isticmaali karaa nooc kasta oo kiimiko ah muddo dheer, waxayna xallisay dhibaatooyin badan oo kiimikaad, Batroolka, daawooyinka iyo qaybaha kale ee dalkeena. Xirmooyinka Ptfe, gaskets, gaskets. Xirmooyinka Polytetrafluoroethylene, gaasaska, gaasaska wax lagu xidho waxay ka samaysan yihiin qaabaynta resin polytetrafluoroethylene oo la hakiyay.
Polytetrafluoroethylene (PTFE) xaaladaha isticmaalka ee warshadaha kiimikada, petrochemical, sifaynta, alkali, acid, bacriminta fosfate, farmashiyaha, sunta cayayaanka, fiber kiimikaad, dheeha, coking, gaaska dhuxusha, synthesis organic, dhalaalid non-ferrous, birta, tamarta atomi iyo sare alaabta nadiifka ah (tusaale, ion xuubka electrolysis), gaadiidka walxaha viscous iyo hawlgalka, cunto caafimaad oo aad u adag, cabitaanada iyo qaybaha kale ee wax soo saarka. Fosfooraska dhexdhexaadka ah, sulfuric acid, nitric acid, hydrochloric acid, acids organic kala duwan, dareerayaasha organic, oksaydhiyeyaasha xooggan iyo warbaahinta kiimikada kale ee xooggan.
Heerkulka -100～280℃, ogalaansho qaboojin degdeg ah iyo kuleyl degdeg ah, ama beddelka hawlgal qabow iyo qabow.
Cadaadis -0.1 ~ 6.4mpa (cadaadiska xun oo buuxa ilaa 64kgf/cm2)
-0.1 ~ 6.4mpa (Fullvacuumto64kgf/cm2)
Giraanta xajinta PTFE inta badan waa in la xoojiyo dhululubada, nidaamka hydraulic ama cadaadiska valve iyada oo aan lumin shaqadiisa xiritaanka, waxay ka hortagi kartaa O-ring "extrusion", hagaajinta isticmaalka cadaadiska, cabbirkeeda waxaa loo habeyn karaa iyadoo loo eegayo shuruudaha macaamiisha.
Giraanta haynta PTFE waa mid heerkul sare u adkaysta -- heerkulka shaqaynta ilaa 250 ℃.
giraanta PTFE iska caabin heerkul hooseeya - oo leh qalab farsamo oo wanaagsan; Xitaa marka heerkulku hoos ugu dhaco -196 ℃, 5% elongation waa la ilaalin karaa.
PTFE xajinta iska caabbinta daxalka - ee kiimikooyinka iyo dareerayaasha intooda badan, oo muujinaya inert, acid xoog leh iyo alkali, biyo iyo noocyo kala duwan oo dareere organic.
PTFE giraanta iska caabinta cimilada - caag ah nolosha gabowga.
PTFE giraanta saliidda sare - waa shay adag oo ku jira isku-dhafka isku-dhafka.
Giraanta PTFE kuma dhegto -- waa xiisadda dusha ugu yar ee alaabta adag oo aan u hoggaansanayn walax kasta.
