Inzululwazi ngasemva kwe-PTFE encamathelayo kwiTape yokuNciphisa-Ukunciphisa iiPropati
Ukubunjwa kwemichiza kunye noLwakhiwo
Iteyiphu encamathelayo ye-PTFE inetyala leempawu zayo ezimangalisayo kubume bayo beekhemikhali ezizodwa. I-Polytetrafluoroethylene (PTFE), eyona nto iphambili, i-synthetic fluoropolymer ye-tetrafluoroethylene. Olu lwakhiwo lweekhemikhali lunika i-PTFE i-non-stick kunye neempawu zayo ezisezantsi. Iibhondi ze-carbon-fluorine kwi-PTFE zomelele ngokugqithisileyo, zenza imolekyuli echasa ukusabela nezinye izinto. Le inertness inegalelo kwiipropati non-stick tape kunye nokumelana imichiza.
Kwinqanaba le-microscopic, iimolekyuli ze-PTFE zenza amatyathanga amade alele ngokuhambelanayo. Eli lungiselelo lidala indawo egudileyo, etyibilikayo kwinqanaba lemolekyuli. Xa imiphezulu emibini egqunywe nge-PTFE idibana, la matsheyina agudileyo emolekyuli atyibilika ngokulula enye kwenye, ekhokelela kukhuhlane olungephi. Le molecular-level smoothness yinto eyenza i-PTFE iteyiphu yokuncamathelisa isebenze kakhulu ekunciphiseni ukukhuhlana kwizicelo ezahlukeneyo.
IiPropati zoMphezulu kunye ne-Friction Coefficient
Iimpawu ezingaphezulu zeteyiphu yokuncamathelisa ye-PTFE, ekwaziwa ngokuba yi- PTFE Teflon iteyiphu yokuncamathelisa , idlala indima ebalulekileyo kwisakhono sayo sokunciphisa ukukhuhlana. I-PTFE ineyona coefficient esezantsi yokukhuhlana kwayo nayiphi na imathiriyeli eqinileyo, ukusuka ku-0.05 ukuya ku-0.10. Ukubeka oku ngokwembono, uninzi lwesinyithi lune-coefficient of friction phakathi kwe-0.5 kunye ne-0.8. Lo mlinganiso wokukhuhlana ophantsi kakhulu uthetha ukuba imiphezulu eqatywe nge-PTFE encamathelayo ifumana ukuxhathisa okuncinci xa udibana nezinye izixhobo.
Ngaphezu koko, amandla omphezulu we-PTFE aphantsi kakhulu, nto leyo enegalelo kwiimpawu zayo zokungakhuni. La mandla amphezulu aphantsi athetha ukuba ezinye izinto zinobunzima bokubambelela kwi-PTFE, iphucula ngakumbi isakhono sayo sokunciphisa ukukhuhlana. Ukudityaniswa kwe-coefficient ephantsi ye-friction kunye namandla aphantsi komhlaba kwenza i-PTFE iteyiphu yokuncamathelisa ibe sisisombululo esifanelekileyo kwizicelo ezifuna intshukumo egudileyo kunye nokuncamathela okuncinci.
