Imvelaphi kunye neePropati ze-PTFE Adhesive Tape
Ukufunyanwa kunye noPhuhliso lwe-PTFE
Ibali le-PTFE liqala ngo-1938 xa uRoy Plunkett, usokhemisti eDuPont, wafumanisa ngempazamo le polima imangalisayo. Ngoxa wayesebenza kwizikhenkcisi, uPlunkett wafumana into emhlophe, enencindi enezinto ezingaqhelekanga. Oku kufunyaniswa ngengozi kukhokelele kuphuhliso lwePTFE, eyathi kamva iDuPont yaphawulwa njengeTeflon ngo-1945.
Ulwakhiwo olulodwa lwemolekyuli lwe-PTFE lunika iimpawu zayo ezikhethekileyo. Ipolymer iqukethe i-carbon backbone ene-athomu ze-fluorine ezibophelelwe ngamandla kuyo, idala izinto ezizinzileyo kunye ne-inert. Olu lwakhiwo lunoxanduva lweempawu ze-PTFE ezingezizo, ukuxhathisa iikhemikhali, kunye nendawo ephezulu yokunyibilika.
Iimpawu eziphambili ze-PTFE Adhesive Tape
I-Teflon i-adhesive tape izuza ilifa ezininzi zezinto eziphawulekayo zesiseko sayo. Ezi teyiphu zinika indibaniselwano yeempawu ezizenza zibe yimfuneko kumashishini ahlukeneyo:
