No ke aha ka paʻakikī o ka PTFE i ka mīkini?

He paʻakikī ka PTFE a me ka hana lua.PTFE meaLoaʻa ka nui o ka emi ʻana a me ka viscosity hoʻoheheʻe kiʻekiʻe loa, no laila ʻaʻole hiki ke hoʻohana ʻia i nā kaʻina hana lua e like me ka injection molding a me ka calendering, i hoʻohana mau ʻia no nā plastics.ʻO PTFE rod ram extruder e hoʻokō i nā pono no ka hana.No laila he aha ka paʻakikī o ka PTFE?

1. ʻAʻohe ʻano mechanical a me ka hiki ke halihali.ʻO ka ikaika mechanical o PTFE he 14 wale nō i ka 25 MPa, me ka ʻole o ke kūpaʻa, akā nui ka elongation fracture.Nui ka coefficient o ka hoʻonui laina.Ma ka -50 ~ 250 ℃, ka PTFE linear hoʻonui coefficient o 1.13 × 10-4 ~ 2.16 × 10-5 / ℃, he 13 manawa o ke kila.No laila, maʻalahi ka hoʻololi ʻana, ka haki, a me nā mea ʻē aʻe me nā mea ʻē aʻe.

2. He maikaʻi ʻole ka wela.ʻO 0.24kcal/(mh-℃) wale nō ka hana wela wela, maʻalahi ke hoʻonui i ka wela, ka luhi wela, a me ka deformation wela.

3. Poor creep kū'ē, oluolu i ke anuanu kahe.ʻO ka PTFE i ka hana lōʻihi o ka ukana, ʻoi aku ka nui o ka kolo, a hiki i ke kahe anuanu.ʻAʻole kū i ka abrasion,PTFEHe haʻahaʻa ka paʻakikī o ke kino, a he nui ka abrasion.Ke ʻoi aku ka haʻawe (P) a me ka wikiwiki hoʻoheheʻe ʻana (V) i kekahi mau kūlana, ʻoi aku ka nui o kona aahu.No laila ua palena iki ka waiwai PV i ka noi a ua kiʻekiʻe nā kumukūʻai hana.ʻO nā hemahema o luna o PTFE e kaupalena i kāna noi, e hoʻomaikaʻi i kāna hana piha.ʻO ka noiʻi ʻana ma ka PTFE ma ka home a me nā ʻāina ʻē i kālele ʻia i ka ʻimi ʻana i nā ala kūpono e hoʻololi ai, pēlā e hoʻomaikaʻi ai i kāna hana i kekahi ʻano a hoʻonui i kāna mau noi.

4. He kūpaʻa maikaʻi hoʻi ia i nā wela kiʻekiʻe a me nā haʻahaʻa haʻahaʻa, kahi e hoʻohana nui ʻia ai i nā noi e like me ka hana ʻana i nā pans non-stick no nā hana anti-adhesive.Hoʻopili piha ʻia ka ʻili o ka mole PTFE e nā ʻātoma fluorine a no laila he ʻano lāʻau ʻole, kahi mea paʻakikī ke hoʻopaʻa ʻia e nā ʻano hana maʻamau.ʻO ke kaʻina hana anti-adhesive he ʻelua mau ʻano nui: kau ʻana i nā ʻāpana PTFE a i ʻole nā ​​​​pepa ma ka substrate a me ka wela-hōʻemi.Nā uhi PTFEa i ʻole ka lole lacquered i hoʻopaʻa ʻia me ke aniani ma luna o ka substrate.
