I-PTFE vs Silicone
Ama-silicones, aziwa nangokuthi ama-polysiloxanes, angama-polymer ahlanganisa noma iyiphi i-inert, inhlanganisela yokwenziwa eyenziwe ngamayunithi aphindaphindayo e-siloxane, okuwuchungechunge lwama-athomu e-silicon ashintshanayo nama-athomu omoya-mpilo, avame ukuhlangana nekhabhoni kanye/noma i-hydrogen.Ivamise ukumelana nokushisa futhi ithanda irabha...Funda kabanzi -
Imikhiqizo ye-PTFE yaseNew York & Abakhiqizi / Abahlinzeki Bemishini
Izifunda nazo azichazeki ngokugcwele ngenxa yokusetshenziswa kwe-colloquial kwamalebula esifunda.UMnyango Wezokuthuthukiswa Komnotho Wesifunda SaseNew York uhlinzeka ngezincazelo ezimbili ezihlukene zalezi zifunda;ihlukanisa izwe libe yizifunda eziyishumi zomnotho, cishe ezihambisana namagama asetshenziswa yi-residen...Funda kabanzi -
I-PTFE vs Rubber
I-PTFE imhlophe ngokwemvelo.Ngakho lelo yigama elingenamsebenzi.Ezinye izinhlobo ze-polymer njenge-FEP ne-PFA zikhanya kakhulu;def hhayi mhlophe.I-PTFE imelana kakhulu namakhemikhali kune-elastomer yakho yezimoto emaphakathi njenge-neoprene ne-EPDM.Lokho "okungcono."Irabha izowohloka kahle ngaphambi kwe-fluor...Funda kabanzi -
I-PTFE vs Perfluorooctanoic Acid (PFOA)
I-Perfluorooctanoic acid (PFOA) (i-conjugate base perfluorooctanoate), eyaziwa nangokuthi i-C8, iyi-synthetic perfluorinated carboxylic acid kanye ne-fluorosurfactant.Uhlelo olulodwa lwezimboni lufana ne-surfactant ku-emulsion polymerization yama-fluoropolymers.Isetshenziswe ekwenzeni i-prom enjalo ...Funda kabanzi -
