I-PTFEiwukuqina kwe-fluorocarbon, njengoba iyinhlanganisela enesisindo esikhulu samangqamuzana ehlanganisa ngokuphelele ikhabhoni nefluorine.I-PTFE i-hydrophobic: akunawo amanzi noma izinto eziqukethe amanzi ezimanzi i-PTFE, njengoba ama-fluorocarbons akhombisa amandla okuhlakazeka ase-London ancishisiwe ngenxa ye-electronegativity ephezulu ye-fluorine.I-PTFE ine-coefficient eyodwa ephansi kakhulu yokungqubuzana kwanoma yikuphi okuqinile.
I-PTFE ayisebenzi kakhulu, ngokwengxenye ngenxa yamandla ebhondi ye-carbon-fluorine, ngakho-ke ivamise ukusetshenziswa ezitsheni nakumapayipi amakhemikhali asebenzayo nabolayo.
.
Izakhiwo zemishini ze-PTFE zingathuthukiswa ngokungeza izigcwalisi ezifana nefiber yengilazi, ikhabhoni, igraphite, i-molybdenum disulphide, nethusi.Ngokuvamile, ama-PTFE agcwalisiwe agcina izici zawo ezinhle kakhulu zamakhemikhali nezinga lokushisa eliphezulu, kuyilapho izigcwalisi zithuthukisa amandla emishini, ukuzinza, nokumelana nokuguga.
Izicelo zihlanganisa ama-wear pads, amaringi e-piston kanye namapulatifomu ajikelezayo kuma-oven ama-microwave.
QAPHELA: Ulwazi oluqukethwe lapha ngamavelu ajwayelekile ahloselwe ireferensi nezinjongo zokuqhathanisa kuphela.AKUMELE zisetshenziswe njengesisekelo sokucaciswa kwedizayini noma ukulawulwa kwekhwalithi.
