Māhele: Polytetrafluoroethylene (PTFE) Mea Teflon
Polytetrafluoroethylene (PTFE) he fluoropolymer synthetic o ka tetrafluoroethylene he nui nā noi ma muli o kona mau waiwai kū hoʻokahi. Ua ʻike ʻia ʻo ia ma kahi pōʻino i ka makahiki 1938 e kahi mea lapaʻau i kapa ʻia ʻo Roy Plunkett ʻoiai ʻo ia e hana ana i ka hoʻomohala ʻana i kahi pahu hau hou. PTFE ʻike maʻamau ʻia e ka inoa inoa ʻo Teflon, nona ka hui kemika ʻo DuPont.
PTFE He mea hoʻopaʻa ʻole a paʻa ka wela i ka nui o nā kemika, me nā waikawa a me nā kumu. He haʻahaʻa haʻahaʻa loa ia o ka friction, e lilo ia i koho maikaʻi loa no ka hoʻohana ʻana i nā noi kahi e makemake ʻia ai ka friction haʻahaʻa, e like me nā bearings a me nā sila. PTFE he insulator uila maikaʻi nō hoʻi, e hoʻohana pono ai i nā noi uila.
ʻO kekahi o nā noi kaulana loa o PTFE aia i loko o ka ipu kuke ʻole. Nā waiwai lāʻau ʻole o PTFE ma muli o kona ikehu ili haʻahaʻa, ka mea e pale ai i ka ʻai mai ka pipili i ka ʻili o ka mea kuke. PTFE hoʻohana ʻia i nā noi ʻē aʻe kahi i makemake ʻia ai nā waiwai non-stick, e like me ka uhi ʻana o nā mea lapaʻau a me ka hana ʻana i nā gaskets a me nā sila.
PTFE hoʻohana pū ʻia i ka ʻoihana aerospace ma muli o kona kūpaʻa wela kiʻekiʻe a me ka coefficient haʻahaʻa o ka friction. Hoʻohana ʻia ia i ka hana ʻana i nā ʻāpana no nā ʻenekini mokulele, e like me nā sila a me nā bearings. PTFE hoʻohana pū ʻia i ke kūkulu ʻana i nā lole lewa ma muli o kona hiki ke kū i ka wela wela a me kāna mau waiwai non-stick.
Ma waho aʻe o kona hoʻohana ʻana i nā ʻāpana non-stick a me nā noi aerospace, PTFE hoʻohana ʻia i ka hana ʻana i nā huahana ʻē aʻe, e like me nā kelepona kamepiula, nā ʻāpana kaʻa, a me nā uhi ʻoihana. Hoʻohana ʻia ia i ka hana ʻana o ka lole Gore-Tex, kahi mea wai a me ka hanu i hoʻohana ʻia i nā lole waho a me nā kāmaʻa.
I ka hopena, PTFE he mea maʻalahi me nā waiwai kūʻokoʻa e hoʻohana pono ai i ka nui o nā noi. ʻO kona ʻano non-reactive, haʻahaʻa haʻahaʻa o ka friction, a me ke kūpaʻa wela kiʻekiʻe e lilo ia i koho maikaʻi loa no ka hoʻohana ʻana i nā pale non-stick, nā ʻāpana aerospace, a me nā noi ʻoihana ʻē aʻe.
