Polytetrafluoroethylene (PTFE)ua ʻike ʻia e ka mea chemist ʻo Dr Roy J. Plunkett ma DuPont's Jackson Laboratory ma New Jersey i ka makahiki 1938. I kona hoʻāʻo ʻana e hana i kahi mea hoʻoheheʻe CFC hou, polytetrafluoroethylene polymerized i loko o kahi pahu hoʻopaʻa paʻa kiʻekiʻe (ʻo ka hao ma ka paia o loko o ka moku i lilo i ka catalyst no ka hopena polymerization). Ua loaʻa i ka hui ʻo DuPont kāna patent ma 1941 a hoʻopaʻa inoa i kāna hōʻailona ma lalo o ka inoa ʻo "TEFLON" ma 1944. Ma hope mai, hoʻomaka ʻo DuPont i kāna ʻoihana ma Teflon & reg; Ma waho aʻe o ka PTFE resin, ua hoʻomohala mākou i nā huahana, me Teflon; AF (amorphous fluoropolymer), Teflon; FEP (fluorinated ethylene propylene resin), Teflon; FFR (fluoropolymer foam resin), Teflon; NXT (fluoropolymer resin), Teflon; PFA (perfluoroalkoxy resin) a pēlā aku.

kāʻei hoʻoili Teflon

ʻO nā huahana o kēia mea i kapa ʻia ʻo "non stick coating"; He ʻano mea polymer synthetic ia e hoʻohana ai i ka fluorine e hoʻololi i nā mana hydrogen āpau i ka polyethylene. Loaʻa i kēia mea nā hiʻohiʻona o ka pale ʻana i ka waikawa, ke kūpaʻa alkali a me nā mea hoʻoheheʻe organik like ʻole, a ʻaneʻane hiki ʻole ke hoʻoheheʻe ʻia i nā solvents a pau. I ka manawa like, loaʻa ka polytetrafluoroethylene i nā ʻano o ke kūpaʻa wela kiʻekiʻe, a he haʻahaʻa loa kona friction coefficient, no laila hiki ke hoʻohana ʻia e like me ka lubrication, a lilo hoʻi i kahi uhi kūpono me ka ʻole o ka pā aila a me ka papa o loko o ka paipu wai.

Hiki ke hoʻohana 'ia Teflon ma conveyor kāʻei: Teflon conveyor kāʻei, Teflon conveyor kāʻei, anu ili conveyor kāʻei, pipeline conveyor kāʻei, Teflon lole, PTFE lole kāʻei, carpet kāʻei, puka moena kāʻei, meaʻai conveyor kāʻei, etc. e hoʻohana pū me ia ma ka lipine: Teflon adhesive tape, Teflon glass fiber adhesive tape, Teflon high temperature resistant tape, self adhesive tape, self adhesive welding fabric, etc.
