ʻO nā hopena koʻikoʻi o ka PTFE Emulsion Particle Size Distribution and Molecular Weight on the Wear Resistance of Glass Fiber Cloth

Teflon kiʻekiʻe-mehana lole mai Jiangsu Aokai New Materials mea he composite mea e pili ana i ke aniani puluniu lole, impregnated me polytetrafluoroethylene (PTFE) emulsion a sintered. He mea koʻikoʻi kona kūpaʻa ʻaʻahu maikaʻi i ka hōʻoia ʻana i ke ola lōʻihi ma lalo o nā kūlana hana ikaika e like me nā kāʻei conveyor, hoʻokuʻu gaskets, a me ka hoʻomaloʻo microwave. ʻO nā kumu nui e hoʻoholo ai i ka pale ʻana o ka lole Teflon kiʻekiʻe-mehana i loko o ʻelua mau hōʻailona o ka emulsion PTFE impregnating: ka hāʻawi ʻana i ka nui o ka nui  a me ke kaumaha mole . Hoʻoholo pololei kēia mau mea ʻelua i ka kūpaʻa, kūlike a me ka paʻakikī o ka ʻili pale pale o Teflon lole wela kiʻekiʻe. No ka hoʻokō ʻana i ke kaʻina hana o ka lole wela kiʻekiʻe ʻo Teflon, pono e hoʻomaopopo i kā lākou hopena koʻikoʻi i ka pale ʻana i ke kapa.

ʻO ka nui a me ka hāʻawi ʻana i nā ʻāpana emulsion e hoʻoholo inā hiki i ka PTFE ke komo like a hoʻopaʻa paʻa i loko o ke aniani fiber framework o Teflon kiʻekiʻe-mehana lole.

ʻO ka nui o ka nui o nā ʻāpana ʻāpana kūpono no ka lole wela kiʻekiʻe o Teflon : ʻO nā emulsions PTFE i hoʻolālā kūikawā ʻia no ka impregnation lole wela kiʻekiʻe ʻo Teflon ma ke ʻano he awelika ka nui o ka pōpō i hoʻomalu ʻia ma 0.15–0.35 µm (150–350 nm) . No ka laʻana, loaʻa i nā emulsions kūikawā no ka lole wela wela ʻo Teflon e like me Chemours DISP 30LX he 0.22 µm. Hiki ke komo pono nā ʻāpana i loko o nā pūʻolo fiber o ka lole wela kiʻekiʻe ʻo Teflon, e hana ana i kahi pale pale paʻa a paʻa ma hope o ka sintering.

Nā hopena maikaʻi ʻole o ka nui liʻiliʻi liʻiliʻi : ʻO ka emulsion maikaʻi loa he nui ka permeability. I ka wā o ka impregnation, ʻaʻole ia e komo nui i loko o ke kua a i ʻole nā ​​​​waha o loko o ka substrate, e hōʻemi ana i nā ʻāpana kūʻokoʻa kūpono i mālama ʻia ma ka ʻili o ka lole wela kiʻekiʻe ʻo Teflon a me ka pōkole o ke ola o ka lole.

Nā hopena maikaʻi ʻole o ka nui o ka nui o ka nui : ʻAʻole hiki i ka emulsion keu loa ke komo i loko o nā ʻāpana aniani o ka lole wela kiʻekiʻe o Teflon, e hana wale ana i kahi uhi pāpaʻu ākea ma ka ʻili. Ke hoʻokau ʻia ka lole wela kiʻekiʻe ʻo Teflon i ka friction ikaika, ʻili maʻalahi kēia uhi paʻa maikaʻi ʻole i nā ʻāpana nui, e alakaʻi pololei ana i ka pau ʻole o ka huahana.

Hoʻoholo ka paona molekula i nā waiwai mechanical a me ka ʻano tribological o ka PTFE polymer ponoʻī, a he mea koʻikoʻi ia i ke ʻano anti-wear o Teflon lole wela kiʻekiʻe.

ʻO ka lole pale wela a me ka lubricating ʻo Teflon : ʻO ke kūpaʻa ʻana o ka lole wela kiʻekiʻe ʻo Teflon e hele mai ana mai kona ʻano haʻahaʻa haʻahaʻa haʻahaʻa. I ka wā o ka friction, hoʻololi nā molekala PTFE ma ka ʻili i ka mea pili, e hana ana i kahi kiʻiʻoniʻoni hoʻoili ponoʻī e pale i ka lole Teflon ponoʻī.

ʻO ka mana kūʻokoʻa o ka paona molekala ma ka hana : Hōʻike nā haʻawina i nā noi lole kiʻekiʻe Teflon, ka PTFE haʻahaʻa-molecular-kaumaha .  hōʻike pinepine ʻia ʻO kēia ke kumu no ka loaʻa ʻana o nā kaulahao molecular haʻahaʻa haʻahaʻa haʻahaʻa i ka PTFE a me ka neʻe ʻoi aku ka kiʻekiʻe o ka neʻe ʻana, e hiki ai i ka wikiwiki a me ka paʻa o ka hoʻokumu ʻana i kahi kiʻiʻoniʻoni hoʻololi maikaʻi i ka wā hakakā ma waena o ka lole a me ka mea hana. ʻO ka ʻokoʻa, ʻo ka PTFE kiʻekiʻe-molecular-kaumaha ka mea e hoʻoulu ai i ka hana lāʻau i ka wā o ka hakakā ʻana, e hōʻeha paha i ka ʻaʻahu kūloko o Teflon lole wela kiʻekiʻe.

ʻO ka hāʻawi ʻana i ka nui o ka ʻāpana e hōʻoia i ka hohonu o ka impregnation a me ka hoʻopili like ʻana o ka uhi ʻana ma ka lole wela wela ʻo Teflon, ʻoiai ke kaumaha o ka molekala e hoʻomaikaʻi i ka hoʻokumu ʻana o ke kiʻi hoʻoili pilikino. Ma ka hoʻomaopopo hohonu a me ka hoʻomalu pono ʻana i ka pilina ma waena o kēia mau mea ʻelua e hiki ai ke hāʻawi ʻia i ka lole wela kiʻekiʻe ʻo Teflon me ka hana anti-wear koʻikoʻi e pono ai no nā kūlana hana hoʻoikaika lōʻihi, e hoʻonui nui i kona ola lawelawe i ka kuke ʻana i ka meaʻai, ka paʻi ʻana i ka maloʻo, photovoltaic lamination a me nā māla ʻē aʻe. ʻO Aokai New Materials e kālele ana i kēia mau hōʻailona microscopic e hōʻoia i ka hana macroscopic kūpaʻa o ka lole wela wela o Teflon.

Hāʻawi ʻia ka ʻike ma luna e Jiangsu Aokai New Materials Technology Co., Ltd.

No nā kikoʻī kikoʻī, nā hiʻohiʻona noi a me nā hoʻonā i hoʻoponopono ʻia o kā mākou huahana piha - me ka lole wela wela ʻo Teflon, ka tape wela wela ʻo Teflon, nā kāʻei mesh wela kiʻekiʻe PTFE, nā kāʻei maʻemaʻe no nā mīkini paʻa, ka lole PTFE ʻaoʻao hoʻokahi, nā kāʻei conveyor kūpaʻa kiʻekiʻe a me nā lole kiʻekiʻe - e ʻoluʻolu e kelepona mai iā mākou ma o fiberglass.
