I-PTFE kunye ne-PVDFzizinto ezimbini ezahlukeneyo zepolymer, kwaye zinomahluko othile kwisakhiwo seekhemikhali, iipropati zomzimba kunye neendawo zokusetyenziswa.
Ulwakhiwo lweekhemikhali:Igama lekhemikhali le-PTFE yi-polytetrafluoroethylene. Yinto ye-polymer ethe ngqo engenamaqela asebenzayo e-polar. Inokumelana okuhle kakhulu nokugqwala, ukumelana nobushushu obuphezulu kunye ne-coefficient ephantsi yokungqubana. Igama lekhemikhali le-PVDF yi-polyvinylidene fluoride, eyinto ye-polymer ethe ngqo enamaqela asebenzayo e-polar. Inokumelana okuhle kakhulu nokugqwala, ukumelana nobushushu obuphezulu, ukumelana nemitha kunye nokukhusela.
Iimpawu ezibonakalayo:I-PTFE ngumgubo omhlophe kubushushu begumbi, ayinyibiliki lula, inomlinganiselo ophantsi wokungqubana kunye nokumelana okuhle kokuguguleka. I-PVDF yikristale engenambala necacileyo enobunzima obuphezulu kunye namandla, kunye nokusebenza okuphezulu kokugoba kwe-dielectric rhoqo kunye nokusebenza okuphantsi kobushushu.
Iindawo zokufaka isicelo:Ngenxa yokuba i-PTFE inokumelana nokugqwala okugqwesileyo kunye nokumelana nobushushu obuphezulu, isetyenziswa kakhulu kushishino lweekhemikhali, izixhobo ze-elektroniki, i-aerospace, ezonyango nakwezinye iindawo, ezifanaUmbhobho osontiweyo we-PTFE, i-gasket yokutywina, imibhobho yobushushu obuphezulu kunye nezinye iimveliso. I-PVDF isetyenziswa kakhulu kwiinkalo zombane, ze-elektroniki, zonyango kunye ne-biotechnology, ezifana nocingo kunye neentambo, izixhobo ze-semiconductor, imibhobho yezonyango kunye nezinye iimveliso.
Ngokubanzi, i-PTFE kunye ne-PVDF zombini zizinto ze-polymer ezisebenzayo kakhulu. Zinomahluko othile kwiindawo zokusetyenziswa kunye neempawu, kwaye kuyimfuneko ukukhetha izinto ezifanelekileyo ngokwendawo ethile yokusetyenziswa kunye neemfuno.
I-Besteflon ingcono kakhuluUmenzi wepayipi ye-PTFEETshayina.Nxibelelana neBesteflon ukuze wazi ngakumbi malunga neetyhubhu zePTFE kunye neemveliso zePTFE ezikumgangatho wehlabathi.
