PTFE ʻO ka Lapaʻau ʻAiʻa Hydrophilic Pāda
PTFE ka lehu ua hoʻohana nui ʻia ma ke ʻano he additive i loko o nā ʻāpana solvent-based a me nā uhi pauka, e like me nā uhi plastik, nā pena lāʻau, nā coil coatings, nā uhi hoʻōla UV, a me nā pena, e hoʻomaikaʻi ai i kā lākou hana hoʻokuʻu ʻana, ka pale ʻana o ka ʻili, ka lubricity, ka pale kemika, pale ʻana i ka wā, a me ka wai ʻole. PTFE hiki ke hoʻohana ʻia nā micro-powders ma ke ʻano he lubricant paʻa ma mua o nā lubricant wai. Hiki iā lākou ke hoʻohana no ka hoʻomaikaʻi ʻana i ke kahe o ka inika a ma ke ʻano he anti-wear agent, me kahi hoʻohui maʻamau o 1-3wt%. Hiki iā lākou ke hoʻohana ʻia i loko o nā pale non-stick no ka mea kuke kuke, me ka nui o ka hoʻohui maʻamau ʻaʻole i ʻoi aku ma mua o 5wt%. Hiki ke hoʻohana ʻia ka dispersion solvent organik ma ke ʻano he mea hoʻokuʻu. Hiki iā lākou ke hoʻohana ʻia ma ke ʻano he anti-drip agents maikaʻi loa i nā plastik like ʻole, e like me ABS, polycarbonate (PC), polyurethane (PU), a me ka polystyrene (PS).
PTFE he polymer crystalline kiʻekiʻe i hana ʻia mai nā monomers tetrafluoroethylene, me ka insulation uila maikaʻi loa, haʻahaʻa haʻahaʻa haʻahaʻa a me friction coefficient, non-flammability, kū'ē i ka wā kahiko o ka lewa, kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa, a me nā waiwai mechanical kiʻekiʻe.
Eia nō naʻe, ma muli o kona ʻano like ʻole a me ka polar ʻole, ka nele o nā pūʻulu ikaika, a me ka crystallinity kiʻekiʻe, PTFE He mea ʻole polar nui me ka hydrophobicity ikaika, kemika inertness, ka ikehu haʻahaʻa haʻahaʻa, a me ka hiki ʻole o ka wettability a me ka hoʻopili ʻana i nā mea ʻē aʻe, kahi e kaupalena nui ai i kāna noi. No laila, e hoʻonui i ka noi o PTFE, pono e mālama ʻia kona ʻili e hoʻonui i ka ikehu o ka ʻili a hoʻomaikaʻi i kona hydrophilicity.
ʻO ka lapaʻau plasma kekahi o nā ʻenehana e ulu wikiwiki nei no PTFE hoʻololi ʻili i nā makahiki i hala iho nei. ʻO ke kumu o ka hoʻololi ʻana i ka plasma ʻo ia ka hoʻohana ʻana i ka ion bombardment a i ʻole injection i ka ʻili o ka polymer e hana i nā paʻa haki a hoʻokomo i nā pūʻulu hana, pēlā e hoʻāla ai i ka ʻili e hoʻomaikaʻi i ka pili ʻana o ka mea. ʻO nā kinoea maʻamau i hoʻohana ʻia he oxygen, hydrogen, nitrogen, carbon tetrafluoride, a me argon. Hiki i ka pahū ʻana o ka plasma gas inert ke hoʻololi i ke ʻano o ka ʻili o ka copolymer.
Loaʻa i ka plasma nā mea hana e like me nā electron, ion, a me nā radical manuahi. ʻO ka hoʻololi ʻana o ka plasma ka hoʻololi kino a me ke kemika. ʻO ka hoʻololi kino, ʻo ia ka pahū ʻana o nā electrons a me nā iona ma ka ʻili polymer, ka mea e uhaʻi ai i nā paʻa kemika o ke kaulahao polymer, hoʻoulu i nā hopena degradation, a hana i nā huahana degradation e waiho ana ma ka ʻili polymer. Hoʻololi ka hoʻololi kemika i ka hoʻokomo ʻana i nā pūʻulu hana ma o nā radical manuahi e pane ana me ka ʻili polymer, e hoʻololi i ka haku mele o ka ʻili. ʻO ka hoʻololi kino a me ka hoʻololi kemika e hoʻololi i nā waiwai ili. I ka wā o ka mālama ʻana i ka plasma, ʻaʻole hiki ke hoʻokaʻawale ʻia ka hoʻokomo ʻana o nā pūʻulu hana a me nā hopena degradation akā hiki i ka manawa like, a ʻaʻole hiki ke pale ʻia nā hopena degradation. ʻO ke kī i ka hoʻololi ʻana i ka ʻili kūpono e hōʻemi i nā hopena degradation a hoʻonui i ka hana o ka hoʻokomo pūʻulu hana.
ka PTFE Hoʻohana ka hoʻololi pauda i ka mīkini hoʻomaʻemaʻe plasma pauda. Hana ʻo Plasma i ka pauka e hoʻololi pono i kona mau waiwai kino a me nā mea kemika, ʻoiai e mālama ana i nā waiwai kumu o ka pauka, e hāʻawi iā ia i nā waiwai ili hou, e hoʻololi ana i kona mau waiwai ili mai ka hydrophobic a i ka hydrophilic a i ʻole ka hoʻololi ʻana, pēlā e hoʻomaikaʻi ai i ka wettability o nā ʻāpana pauda. ka hoʻonui ʻana i ka hoʻopili ʻana o nā ʻāpana pauda i loko o ka waena.
