(Sharaxaad kooban) PTFE EPDM kursiga waalka balanbaalista
Teflon PTFE waxa kale oo loo yaqaan polytetrafluoroethylene. Waa maxay faa'iidada iyo khasaaraha mid kasta? Farqiga u adkaysiga heerkulka, keebaa ka jaban?
Kala duwan ee dabeecadda
1.PFA: copolymer ah qadar yar oo ah perfluoropropyl perfluorovinyl ether iyo polytetrafluoroethylene.2.PTFE: xarun polymer ah oo lagu sameeyay polymerization of tetrafluoroethylene.
Sifooyin kala duwan
Tilmaamaha PFA
(1) Walxaha crystal, nuugista qoyaanka hooseeya.Waxa lagu farsamayn karaa alaabada hababka habaynta thermoplastic.
([2) Wasakhnimo, fududahay in la dumiyo iyo gaasta daxalka ah ayaa la abuuraa inta lagu jiro kala-goynta. Heerkulka qaabaynta kama badna 475 ° C, caaryada waxaa lagu kululeeyaa 150-200 ° C, iyo nidaamka shubida wax yar iska caabin ah socodka walxaha.
(3 Pelles Trasucent, ijection molding and extrusion molding. Heerkulka qaabaynta waa 350-400C, 475℃ iyo wixii ka sareeya way fududahay in ay keento midab ama finan. U fiirso dhibka duminta.
(4) Saamaynta daxalka ee walxaha dhalaalaysa ee birta awgeed, wax-soo-saarka muddada dheer wuxuu u baahan yahay chrome ku dhejinta caaryada. sifooyinka PTFE
Sifada PTFE
(1) Iska caabin heerkul sare ah: heerkulka isticmaalka muddada dheer 200 ~ 260 ℃;
(2) Iska caabin heerkul hooseeya: jilicsan at -100 ℃;
(3) Iska caabinta daxalka: u adkaysta aqua regia iyo dhammaan dareerayaasha organic;
(4) Iska caabinta cimilada: nolosha gabowga ugu fiican ee balaastikada;
(5) Saliid sare: oo leh isku-dhafka ugu yar ee isku-dhafka (0.04) ee balaastikada ah;
(6) Dheg la'aan: Waxay leedahay xiisadda dusha ugu yar ee alaabta adag iyada oo aan loo hoggaansamin wax kasta.
Farqiga ugu weyn ayaa ah in PFA ay fududahay in la farsameeyo oo ka qaalisan yahay PTFE, laakiin ficil ahaan PTFE waxay leedahay iska caabin daxaleed oo ka wanaagsan sidoo kale waxay u adkaysataa heerkulka sare.
