PTFEhe fluoropolymer palupalu, ʻaʻole ʻona me ka helu haʻahaʻa haʻahaʻa o ka friction, ʻo ia hoʻi he liʻiliʻi nā mea e pili ana iā ia, a ʻo ka hapa nui o nā lāʻau e hiki ke ʻili a ʻoki ʻia paha.Loaʻa i ka PTFE ke kūʻē kemika a me ke anuanu.ʻAʻole hiki ke hoʻoheheʻe ʻia ʻo PTFE i ka hapa nui o nā organika a loaʻa iā ia nā waiwai uila maikaʻi loa.Paʻa mau ia ma nā mahana cryogenic a me nā wela kiʻekiʻe (mai -400° F a hiki i 500° F), ʻoiai he haʻahaʻa kona ʻano mechanical i ka hoʻohālikelike ʻia me nā plastic engineering ʻē aʻe.Hiki ke hoʻomaikaʻi ʻia nā mea mechanical, uila a me ka wela o ka PTFE ma o ka hoʻohui ʻana i nā mea hoʻopihapiha e like me ke aniani fiber, carbon, graphite, bronze a me ka molybdenum disulfide (MoS2).ʻO nā noi maʻamau e pili ana i nā sila, bearings, bushings, coil separators, terminals, a me nā paipu paʻa a me nā pono.
ʻO ka PTFE ka wehewehe kemika no polytetrafluoroethylene, a i ʻole i ʻike ʻia ʻo DuPont's polymer.Nui nā mea hoʻolako ʻē aʻe i hana i nā resins PTFE granular a me nā kahe manuahi.
ʻO TFE ka inoa kemika no ka tetrafluoroethylene, he kinoea kala ʻole a me ka ʻai ʻole, ʻona loa a make loa.
Mai huikau i nā mea ʻelua, ʻoiai ua hoʻohana hewa ka ʻoihana plastics i kēia mau huaʻōlelo i nā makahiki i hoʻololi ʻia.
ʻO TFE ka monomer mua no ka hana ʻana i ka PTFE.No laila, manaʻo wau ʻaʻole lākou i hoʻopilikia i ka 'P'.ʻO FEP a me PFA ʻelua mau ʻano like ʻole o ka polymer.Hiki ke hoʻoheheʻe ʻia lākou ʻoiai ʻaʻole PTFE.ʻO nā ʻano like ʻole a pau he paʻakikī ke hoʻopaʻa ʻia.ʻO nā hana maʻamau i hoʻohana ʻia no ka hoʻopaʻa ʻana, ʻo ia ka etching chemical (malia paha ka mea āu e hoʻāʻo nei), plasma pre-etching, corona treatments, etc.
Hiki iā ʻoe ke nānā i kā mākou huahana PTFE (kookoo ptfe, paipu ptfe, paipu a me ka paipu) no ka laʻana manuahi.
