Nā ʻokoʻa ma Fluorophlogopite a me Natural Mika a me Polytetrafluoroethylene

1. Hana uila:

Ma muli o ka maʻemaʻe o ke kino,FluorophlogopiteHe kiʻekiʻe ka nui o ka resistivity (ma kahi o 1000 mau manawa kiʻekiʻe ma mua o ka mika maoli), a hiki i ka mahana hoʻohana palekana ke hiki i 1100 ℃.Ke emi nei ka ikaika o ka nahaha uila o ka mika fluoro-crystalline me ka hoʻonui ʻia o ka mānoanoa o ka mica.Mika maoliloaʻa i ka nui o nā haumia, a ʻaʻole kūpaʻa kona mau waiwai uila, a ʻoi aku ka maikaʻi o kāna mau waiwai uila i ka wela kiʻekiʻe a me ke alapine kiʻekiʻe.Ke piʻi ka mahana ma luna o 500 ℃, e nalo mālie ʻo ia i kāna mau waiwai mika ma muli o ka dehydration.

ʻO ka Polytetrafluoroethylene ka maikaʻi o ka hana hoʻokaʻawale uila, akā no ka maʻalahi o ka noho ʻana o nā haumia metala i ka hana ʻana o polytetrafluoroethylene, pēlā e hoʻopili ai i ka hana uila.ʻAʻole maikaʻi ka pale ʻana o ka corona o polytetrafluoroethylene, no laila ʻaʻole hiki ke hoʻohana ʻia e like me kahi mea hoʻokalakupua kiʻekiʻe, ʻaʻole hiki ke hoʻohālikelike ʻia me ka fluorite mica.
2. ʻO ka hana ʻana o ka hoʻoheheʻe ʻana:

He haʻahaʻa ka hoʻokuʻu ʻia ʻana o ke kinoea māmā o fluoro-crystalline mica, a ʻo nā kinoea i hoʻokuʻu ʻia e ka spectrometer mass he mau kinoea adsorbed wale nō e like me O2, N2 a me Ar.No ka mea, ʻaʻole ia e hoʻokuʻu i ka mahu H2O, he mea waiwai nui ia no ka hoʻohana ʻana i mea hoʻokalakupua uila, hiki ke hoʻomaikaʻi maikaʻi i ke ola lawelawe o nā mea ʻenekini.

Na ka mika maoli e hoʻoheheʻe i ka H2O a me nā ʻāpana ʻē aʻe i ka wela kiʻekiʻe, no laila ke kiʻekiʻe ka hoʻokuʻu ʻana o ka ea.Ma kahi o 900 ℃, he 2000 mau manawa kiʻekiʻe ma mua o ka fluorite mica.

He paʻakikī ke ʻano o ka polytetrafluoroethylene a loaʻa iā ia kekahi mau waiwai ʻā.He haʻahaʻa haʻahaʻa loa ia, haʻahaʻa haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa haʻahaʻa i ka lumi wela, akā ua kaupalena ʻia e ka mahana o ka hoʻohana ʻana, a ʻaʻole maʻalahi ka hoʻohana ʻana i ke kiʻekiʻe o ka wela a i ʻole ka mahana ʻole.

ʻĀpana hoʻoheheʻe ʻana o ka mika fluorophrystalline i ka wela kiʻekiʻe

3, hana kino:

ʻAʻole maʻalahi ka fluorocrystalline mica i ka deform, hiki ke kū i ke kaomi nui, a loaʻa ka ikaika tensile kiʻekiʻe a me ka ikaika compressive.E kahe ana ʻo Teflon a nahā i nā ukana kiʻekiʻe.Ke ʻoi aku ka kiʻekiʻe o ka hoʻouka ʻana ma mua o 3MPa, e hoʻololi ʻia ke koena deformation, a i ka wā e hoʻouka ai ma kahi o 20MPa, e ʻoki ʻia.ʻAʻole maikaʻi ʻo Ptfe, maʻalahi e hoʻololi i lalo o ke koʻikoʻi lōʻihi, ikaika tensile, ikaika kulou, ikaika hopena, rigidity, hardness, creep resistance, fatigue resistance a me nā waiwai ʻē aʻe.
