Polytetrafluoroethylene (PTFE) yi-fluoropolymer yokwenziwa ye-tetrafluoroethylene enezicelo ezininzi.Elona gama lebhrendi laziwa kakhulu lePTFE-sekwe…
I-PolyTetraFluoroEthylene yipolymer esekwe ku-fluorocarbon kwaye iqhelekile ukushunqulelwa i-PTFE.Abanye abavelisi abaninzi benza iibrendi zabo ze-PTFE ezinokuthi zisetyenziswe njengezinto ezibambeleyo.Le ntsapho ye-fluoroplastic inikezela ukuchasana kweekhemikhali eziphezulu, amandla aphantsi kunye nobushushu obuphezulu, ukuchasana nemozulu, ukungqubuzana okuphantsi, umbane kunye ne-thermal insulation, kunye "nokutyibilika".(jonga kwakhona i-polymer® PTFE kunyeipholima® FEP & PFA Specifications ) Iimpawu ze-PTFE zoomatshini ziphantsi xa kuthelekiswa nezinye iiplastiki, kodwa iimpawu zayo zihlala zikwinqanaba eliluncedo kuluhlu olubanzi lobushushu ukusuka -100 °F ukuya +400°F (-73°C ukuya ku-204°C) .Iimpawu zoomatshini zihlala ziphuculwa ngokongeza izihluzi (jonga umhlathi ongezantsi).Ineempawu ezigqwesileyo zobushushu kunye nombane kunye ne-coefficient ephantsi yokukhuhlana.I-PTFE ixinene kakhulu kwaye ayinakunyibilikiswa iqhubekeke — kufuneka icinezelwe kwaye igxininiswe ukwenza iimilo eziluncedo.
Iipropati zoomatshini ze-PTFE zinokuphuculwa ngokongeza izihluzi ezifana neentsinga zeglasi, ikhabhoni, igraphite, imolybdenum disulphide, kunye nobhedu.Ngokubanzi, ii-PTFE ezigcwalisiweyo zigcina iikhemikhali ezibalaseleyo kunye neempawu zobushushu obuphezulu, ngelixa izihluzi ziphucula amandla oomatshini, uzinzo, kunye nokumelana nokunxiba.Iipropati ze-25% zeglasi ezizaliswe kunye ne-25% ye-carbon-filled PTFE amabakala aboniswe ngezantsi ngeenjongo zokuthelekisa.Kukho ngokwenene ezininzi zeemveliso ezahlukeneyo ze-PTFE kunye namabanga - zininzi kakhulu ukuba zidweliswe apha.
IIPROPATI EZIQHELEKILEYO ze-PTFE
QAPHELA: Ulwazi oluqulethwe apha ngamaxabiso aqhelekileyo enzelwe ireferensi kunye neenjongo zokuthelekisa kuphela.AKUMAKUFUNEKA zisetyenziswe njengesiseko senkcazelo yoyilo okanye ulawulo lomgangatho.Qhagamshelana nathi ukuze ufumane iinkcukacha ezipheleleyo zepropathi yempahla yabenzi.Onke amaxabiso kwi-73°F (23°C) ngaphandle kokuba kuchazwe ngenye indlela.
