Isku-dhafka Balaadhinta Caagga Dabacsan ee PTFE
Sharaxaada
Kala-goysyada ballaarinta caagga ah ee PTFE waxay leedahay astaamo hoos u dhac ku yimaada gariir, ka-hortagga-daxalka, caabbinta aashitada iyo alkali, iska caabbinta heerkulka sare, dabacsanaanta iyo caabbinta xoqida, inta badan loo isticmaalo barokaca dhuumaha, isbeddelka cabbirka iyo isku xirka qaybta gariirka, waxaa loo isticmaali karaa sahayda iyo dheecaanka. dhuumaha qashinka, injineernimada kiimikada, daxalka, qalabka taangiga vulcanization, iyo isticmaalka kale ee gaarka ah.
PTFE waa u gaaban Polytetrafluoroethylene, oo sidoo kale loo yaqaan Teflon, 4F.PTFE waxay leedahay xasillooni kiimiko heer sare ah iyo iska caabin daxalka, waa mid ka mid ah walxaha iska caabbinta daxalka ugu fiican adduunka, marka laga reebo sodium bir ah iyo fluorine dareere ah, PTFE waa iska caabin dhammaan kiimikooyinka, oo si ballaaran loo isticmaalo dhammaan deegaannada daxalka.Ka sokow, waxa ay leedahay hanti shaabadeynta wanaagsan, hantida saliidda sare, hantida dahaaran koronto, iska caabin gabow wanaagsan, iska caabin heerkulka (waqti dheer shaqayn kartaa inta u dhaxaysa -180 ℃ in 250 ℃).
Astaamaha badeecada ee kala goysyada fidinta caagga ah ee PTFE:
Iska caabin heerkul sare ah: heerkulka shaqadu waa ilaa 250 ℃.
Iska caabbinta heerkulka hooseeya: waxay leedahay adkaysi mashiinada oo aad u fiican, xitaa haddii heerkulku hoos ugu dhaco -196 ℃, waxay ilaalin kartaa dhererka 5%.
Iska caabinta daxalka: caabbinta kiimikooyinka intooda badan.
