Thepa e Ikhethang ea PTFE Film Tape
Sebopeho sa Lik'hemik'hale le Sebopeho
Theipi ea filimi ea PTFE e entsoe ka polytetrafluoroethylene, fluoropolymer ea maiketsetso ea tetrafluoroethylene. Sebopeho sena se ikhethang sa lik'hemik'hale se fa PTFE thepa ea eona e ikhethang. Litlamo tsa carbon-fluorine ho PTFE li matla ka mokhoa o makatsang, 'me li etsa hore ho be le thepa e sa sebetseng ho lik'hemik'hale tse ngata le lihlapolli. Sebopeho sa limolek'hule tsa PTFE se etsa hore ho be le sebaka se boreleli, se se nang thupa boemong ba microscopic, e leng senotlolo sa litšobotsi tsa eona tse tlaase tsa likhohlano.
Tlase Coefficient of Friction
E 'ngoe ea litšobotsi tse ikhethang tsa tepi ea filimi ea PTFE ke coefficient e tlase haholo ea likhohlano. Sena se bolela hore ha libaka tsa PTFE li thella khahlanong le tse ling kapa lisebelisoa tse ling, li ba le khanyetso e fokolang. The coefficient of friction for PTFE is usually around 0.05 to 0.10, e leng tlase ho feta tse ling tse ngata tse tiileng thepa. Thepa ena e etsa tepi ea sekhomaretsi ea filimi ea PTFE e loketseng lits'ebetso moo ho fokotsa likhohlano ho leng bohlokoa, joalo ka li-bearings, litiiso le mekhoa ea ho thella.
