Polytetrafluoroethylene (PTFE)waxaa helay farmashiistaha Dr Roy J. Plunkett ee DuPont's Jackson Laboratory ee New Jersey 1938. Markii uu isku dayay inuu sameeyo qaboojiye cusub oo CFC ah, polytetrafluoroethylene polymerized weelka kaydinta cadaadiska sare (birta derbiga gudaha ee markabka ayaa noqotay kicinta falcelinta polymerization). Shirkadda DuPont waxay heshay patent-keeda 1941 waxayna ka diiwaan gashan tahay calaamadeeda magaca "TEFLON" 1944. Kadib, DuPont waxay ganacsigeeda ka bilowday Teflon & reg; Marka lagu daro resin PTFE, waxaanu soo saarnay alaabooyin taxane ah, oo ay ku jiraan Teflon; AF (fluoropolymer amorphous), Teflon; FEP (resin ethylene propylene fluorinated), Teflon; FFR (resin fluoropolymer), Teflon; NXT (resin fluoropolymer), Teflon; PFA (perfluoroalkoxy resin) iyo wixii la mid ah.
Suunka qaada Teflon
Alaabooyinka walxahan waxaa guud ahaan loo tixraacaa sida "daahan aan dhejis ahayn"; Waa nooc ka mid ah walxaha polymer synthetic kaas oo isticmaala fluorine si uu u beddelo dhammaan atamka hydrogen ee polyetylen. Qalabkani wuxuu leeyahay sifooyinka caabbinta aashitada, caabbinta alkali iyo dareerayaasha organic kala duwan, waxayna ku dhowdahay inaan la milmin dhammaan dareerayaasha. Isla mar ahaantaana, polytetrafluoroethylene waxay leedahay sifooyin caabbinta heerkulka sare, iyo isugeynteeda iskuxiran waa mid aad u hooseeya, sidaas darteed waxaa loo isticmaali karaa sifeyn ahaan, sidoo kale waxay noqotaa dahaar ku habboon iyada oo aan lahayn digsiga saliidda iyo lakabka gudaha ee tuubada biyaha.
Teflon waxaa loo isticmaali karaa suunka gudbinta: suunka gudbinta Teflon, suunka gudbinta teflon, suunka wareejinta maqaarka qabow, suunka dhuumaha qaada, maro Teflon, suunka marada PTFE, suunka rooga, maro albaabka, suunka gudbinta cuntada, iwm. Dabcan, waan awoodnaa. sidoo kale ku isticmaal cajaladda: Cajaladda koollada ee Teflon, Cajaladda fiber-ka dhalada ah ee Teflon, Cajalad heer-kulka sare leh oo Teflon ah, sharooto is-xabag ah, maro alxan leh oo iskeed isku dhejisa, iwm.
