ʻO ka Ua ulana ʻia ka lole mai nā kaula aniani he nui ma ka mānoanoa, twill, a i ʻole nā mea ulana ʻē aʻe e hana i ka iwi iwi, me nā anawaena monofilament pākahi mai nā microns a ʻoi aku i ʻumi microns, a me ka ʻili maʻemaʻe.
2. Porosity kiʻekiʻe
Ma mua o ka uhi ʻana, nui nā pores micron-scale i loko o nā pūʻulu fiber a ma nā nodes intersection warp-weft, e hāʻawi ana i wahi no ka impregnation PTFE ma hope.
II. ʻO ka Morphology Coating: ʻO ka 'Island-Coating' Structure of PTFE
1. Full Impregnation Encapsulation
Komo ka resin PTFE i loko o nā āpau ma waena o kēlā me kēia filament, e hana ana i ka 'reinforced concrete' -type composite, kahi e lawelawe ai nā fibers aniani ma ke ʻano hoʻoikaika a ʻo ka PTFE ka matrix mau. Ma ka ʻāpana keʻa, hiki ke ʻike ʻia nā fibers i hoʻopili ʻia i loko o ka resin.
2. Surface Nodular Microstructure
Hōʻike ka ʻili PTFE maʻemaʻe i kahi morphology pūnaewele ʻokoʻa o nā nodules (particles) i hoʻopili ʻia e nā fibrils maikaʻi, i hana ʻia e ka hui ʻana o nā lamellae pelu ʻia i ka wā o ke kaʻina sintering, e hāʻawi ana i nā waiwai ʻole a me ka lubricating ponoʻī i ka mea.
3. Hoʻopaʻa ʻili Paʻa mau
Hoʻonui ʻia ka ʻili o ka ʻili me ka PTFE maʻemaʻe, e hana ana i kahi kiʻi ʻoniʻoni aniani-fiber-free ʻili i nā ʻumi o nā microns mānoanoa, e lawelawe ana i ka pale kī no ka inertness kemika, nā waiwai non-stick, a me ka insulation uila.
III. Nā Kuleana Kiʻi: Microporosity a me nā hiʻohiʻona Interface
1. Koena Micropores
ʻO ka impregnation a i ʻole ka emi ʻana i ka wā o ka sintering hiki ke waiho i nā micron-scale voids a i ʻole nā māwae ma ke kikowaena o nā pūʻulu fiber a me nā node interweaving, e alakaʻi ana i ka hoʻemi ʻana i ka hoʻokuʻu ʻana a me ke kūpaʻa kemika.
2. Hoʻopaʻa Interface
ʻAʻole kūpono nā pulu aniani a me ka PTFE; hiki ke ʻike ʻia ma ka microscopically, nā lua laumania i waiho ʻia e ka huki huki waho. Ma o ka hoʻopili ʻana i ka lāʻau lapaʻau a i ʻole ka hoʻopili mechanical, hoʻopaʻa paʻa ʻo PTFE i nā fibers, e hoʻomaikaʻi ana i ka ikaika paʻa interfacial.
IV. Nā ʻano o ka mokuʻāina i hoʻopaʻa ʻia: Semi-Crystalline Structure
1. Spherulites a me nā Crystal Banded
ʻO PTFE kahi polymer semi-crystalline. Ma hope o ka sintering maʻamau, hōʻike ia i ka noho like ʻana o nā spherulites a me nā kristal banded, me ka crystallinity maʻamau mai 50% a 70%, a me ka hoʻonohonoho pono ʻana o ke kaulahao molecular.
2. Ka hopena o ka Crystallinity
Hāʻawi ka crystallinity kiʻekiʻe i ka mea me ke kūpaʻa wela no ka wā lōʻihi a hiki i 260 ° C a me ke kolo wela haʻahaʻa haʻahaʻa loa. ʻO ka over-sintering a i ʻole ka under-sintering hiki ke alakaʻi i nā kūlana crystalline maʻamau, e hōʻemi i ke ola lawelawe.
Inā makemake ʻoe e aʻo hou aʻe e pili ana i nā kikoʻī kikoʻī, nā hiʻohiʻona noi, a me nā hoʻoponopono hoʻoponopono no kā mākou piha piha o nā huahana, e like me Teflon kiʻekiʻe-mehana lole, Teflon kiʻekiʻe-mehana lipine, Teflon kiʻekiʻe-mehana mesh kāʻei, seamless conveyor kāʻei no nā mīkini hoʻopaʻa, hoʻokahi ʻaoʻao PTFE lole, kiʻekiʻe-mehana, a kūpaʻa kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe mesh kāʻei, nā kāʻei conveyor seamless no nā mīkini hoʻopaʻa, ʻaoʻao hoʻokahi ʻaoʻao PTFE, kiʻekiʻe-mehana, kūpaʻa kūʻokoʻa kiʻekiʻe kiʻekiʻe. ma o keia:
Hoʻopili mau mākou i kahi loea lawelawe ʻoihana a hilinaʻi, a ke kūpaʻa piha nei mākou i ka hāʻawi ʻana iā ʻoe i nā hopena hoʻokahi a me ka lawelawe hoʻolohe!
