Imbali yePolytetrafluorororoothene yaqala ngo-Epreli 6, ngo-1938 kwi-Duockson's jackson's jackson's jackson ejeyey eNew Jersey. Ngomhla wethamsanqa, uGqirha Roy J. I-Plum Plungoket, eyayisebenza neegesi ezinxulumene ne-freon frients ezinxulumene ne-freyfrieds, yafumanisa ukuba i-polymeraged molneedy ngokuzenzekelayo, i-waxy eqinile.

Uvavanyo lwabonisa ukuba le nto iqinileyo yayisisixhobo esimangalisayo. Yayili-resin eyasiyeka yonke imichiza eyaziwayo okanye isolweyo; Umphezulu wayo wawunqabile kangangokuba akukho nto ingayinamathela kuyo; Ukufuma kwakungekakubangela ukuba idumbe, kwaye ayizange ilahle okanye ibe yi-brittle emva kokuvezwa kwexesha elide ekukhanyisweni kwelanga. Yayinendawo yokunyibilika yama-327 ° C kwaye, ngokuchasene ne-ThermoPrics eqhelekileyo, ayizukuhamba ngaphezulu kwendawo yokunyibilika. Oku kuthetha ukuba iindlela ezintsha zokulungisa ziphuhliswe ukuze zihambelane neempawu ze-resin entsha - yeyiphi i-du pont ene-teflon.

Iindlela zokubolekwa kwi-powergergy, iinjineli ze-du pont zakwazi ukucinezela kunye ne-sooter PolytetraFlUorofluobene e-Robs ezinokuthi zibekho nayiphi na imilo enqwenelekayo. Emva kwexesha, ukusasazeka kwe-resin emanzini kwaqulunqwa kwilaphu leglasi kunye nokwenza i-inamels. Umgubo waveliswa onokuthi udityaniswe ne-wibricant kwaye ikhutshiwe kwi-wiot wire kwaye ivelise ityhubhu.

By 1948, 10 years after the discovery of POLYTETRAFLUOROETHYLENE, Du Pont was teaching processing technology to its customers. Kungekudala isityalo sentengiso sasisebenza, kwaye i-polytetrafluoroothylene ptfey ifumaneke kwisasazo, amagxalale kunye nomgubo ocolekileyo.

Kutheni ukhetha i-ptfe hose?

I-ptfe okanye i-polytetrafluoroothylene yenye yezona ndawo zixhaphaza ngamachiza. Oku kwenza ukuba i-dusses ye-ptfe iphumelele ngaphakathi koluhlu olubanzi lwamashishini apho iiduli zemveli zemveli okanye irabha zinokusilela. Bhanga le nto kunye noluhlu lobushushu obuhle (-7 ° ukuya kwi + 260 ° C) kwaye ugqibela ngengozi eqinileyo kakhulu ekwaziyo ukwenziwa kweyona ndawo ibalaseleyo.

Iipropathi ezingenantlonelo ze-ptfe ivumela amaxabiso okuqala okuhamba xa ehambisa izixhobo ze-viscous. Oku kubandakanya negalelo uyilo olucocekileyo olucocekileyo kwaye ngokusisiseko kudala i-liner 'ye-HATARE'
