PTFE aad bay ugu adkaysanaysaa daxalka kiimikaad ahaan marka loo eego PVDF ama PE.Inta badan atamka Fluorine ee laf dhabarta, barootiinada badani ma awoodi doonaan inay si kiimiko ah ugu dhejiyaan dusha sare.
Farqiga ugu weyn ee u dhexeeya PTFE iyo PVDF
| Polymer | PVDF | PTFE |
| Qaab dhismeedka | –[–CF2–CHF–] n– | –[–CF2–CF2]n – |
| Farsamada Wax-soo-saarka | dharbaaxo | Cadaadiska isostatic kulul ama qabow iyo/ama sintayn |
| Isticmaalka kicinta iyo/ama wax-soo-saarka kale | Cd, Ba, K | Midna |
| Qiimo | Dhexdhexaad | Sare |
| Cufnaanta [g/cm3] | 1.8 | 2.1 ilaa 2.3 |
| Barta dhalaalka [°C] | 178 | 327 |
| Heerkulka Heerkulka ee Codsiga [°C] | -60 ilaa 150 | -200 ilaa 260 |
| Xoogga Jilicsan | 50 | 20 ilaa 35 |
| Iska caabin kiimikaad | Xog dheeraad ah lagama hayo;oo la mid ah PTFE | Gaar ah.Aan guban oo aan lagu xallin karin dhammaan dareerayaasha la yaqaan.Waxaa lagu weeraray kaliya biraha alkali ee dhalaalay iyo fluorine oo heerkul sare ah. |
PTFE iyo PVDF (durapore) ayaa labadaba loo isticmaalaa xuubka shaandhada borotiinka ee xidha (gaar ahaan Millipore).Kiimiko ahaan labada polymers aad bay u kala duwan yihiin sababtoo ah fluoride-yada dheeraadka ah iyo miisaanka kelliyada.Waxyaabaha ay ku xidhan yihiin borotiinku sidoo kale way kala duwan yihiin.
Guud ahaan, PTFE way ka badan tahay 'aan dheg lahayn' marka loo eego PVDF, taas oo aad uga badan polyetylen (PE).PTFE aad bay ugu adkaysanaysaa daxalka kiimikaad ahaan marka loo eego PVDF ama PE.Waad ku saxan tahay inaad eegto qaabka kiimikada.Inta badan atamka Fluorine ee laf dhabarta, barootiinada badani ma awoodi doonaan inay si kiimiko ah ugu dhejiyaan dusha sare.Cabbiraadda waxyaabaha sida xagasha xidhiidhka ayaa taas xaqiijin doonta.Ma garanayo inta qaab-dhismeedka daldaloolada ee xuubabka ay wax u saameeyaan, laakiin marka la eego dhinaca kiimikada, waxaa jira kala duwanaansho cad.
PTFE-poly tetra fluoro ethylene iyo PVDF-polyvinylidene fluoride labaduba waa polymers loo isticmaalo hantida hydrophobic ee electrode si looga fogaado daadinta walxaha cathode (maro kaarboon) inta badan daraasadaha, waxay isticmaalayaan xal PTFE marka loo eego noocyada kale ee xalka ...
Labaduba waa kuwo deggan oo ku filan.Ka fakar in sababtu ay ku jirto qaab-dhismeedka electrode-ga kama dambaysta ah, sababtoo ah PVDF binder loo isticmaalo xal dhab ah (xabag), halka PTFE mid ka mid ah uu yahay ganaax leh qaybo nanosized ah oo aan milmi karin.
PVDF ayaa ka falcelis badan PTFE marka loo eego xaaladaha qaarkood.
PS: Haddii aad rabto muunad ama macluumaad dheeraad ah oo ku saabsan PTFE usha la shubay vs PTFE tubbada PTFE, tuubada PTFE, iyo qalabka PTFE, fadlan nala soo xidhiidh.
