ʻO ka hiʻohiʻona ulana fiberglass - maʻemaʻe, twill, a i ʻole satin - pili nui i nā waiwai lole wela wela PTFE. Hāʻawi ka ulana satin i ka ikaika haʻalulu kiʻekiʻe (2-3x maʻemaʻe) a me ka maʻalahi, kūpono no ke kuʻi ikaika. Hāʻawi ka ulana maʻemaʻe i ka paʻa o ka dimensional maikaʻi loa a me ka hoʻopili ʻili, kūpono no nā noi static. Hoʻohālikelike ʻo Twill i nā waiwai āpau no ka hoʻohana maʻamau.

Pono ʻo PTFE fiberglass tape i ʻekolu mau palapala hōʻoia palekana: UL (palekana uila a me ka lapalapa ahi), FDA (hoʻopili pili meaʻai), a me ISO 9001:2015 (hoʻokele maikaʻi). Hāʻawi nā lipine i hōʻoia ʻia i ka hana maʻamau, ke ola ʻoi aku ka lōʻihi o ka lawelawe ʻana, a me ka haʻahaʻa haʻahaʻa o ke kumu kūʻai ʻoiai ke kumu kūʻai kiʻekiʻe. E hōʻoia mau i nā palapala hōʻoia me nā hui hoʻopuka.

ʻO nā kāʻei conveyor PTFE (Teflon kāʻei) hoʻomaikaʻi i nā laina hana meaʻai ma o ʻehā mau pōmaikaʻi nui: ʻoi aku ka maikaʻi o ka hana non-stick (hōʻemi i ka ʻōpala a me ka pipiʻi ʻana), ka hoʻomanawanui ākea ākea (-100 ° C a hiki i 260 ° C hiki i ka kuke ʻana i ka maloʻo), ka hoʻomaʻemaʻe maʻalahi a me ka pale ʻana i ka maʻi bacteria (non-porous surface, FDA compliant), a me ka mālama kālā (hoʻohana haʻahaʻa i ka ikehu, lōʻihi ke ola kāʻei). He kūpono no nā meaʻai i kālua ʻia, nā meaʻai maloʻo, ke kokoleka, a me nā huahana pili.

Hoʻohana ʻia ka lipine wela kiʻekiʻe o ka PTFE ma waena o ʻekolu mau lāʻau noiʻi lapaʻau: ka pale ʻana i nā mea hana sterilization (autoclave trays, heat-seal packaging), mea hoʻomaʻamaʻa ʻili (ka uhi haʻahaʻa haʻahaʻa, insulation uila), a me nā mea implantable (vascular grafts, sutures). Ua hōʻoia ʻia ka biocompatibility ma o ISO 10993, a ua hoʻokumu ʻo FDA 21 CFR 177.1550 i ka palekana kumu.

Hoʻoholo ʻia ka hoʻohui like ʻana o ka lole PTFE kiʻekiʻe-mehana e nā kumu ʻehā: ka uhi ʻana (ka nui o nā ʻāpana 0.15-0.35 μm, viscosity, solid content), ka uhi ʻana a me ke kaʻina hana sintering (makemake ʻia ka uhi ʻana no ka like ʻole), ka maikaʻi o ka substrate (weave pattern, pre-treatment), a me ka ʻenehana hana (20-25% R, <60 ° C). ʻO ke kaʻina hana hoʻohui ʻia ʻo Dip + blade e kaulike i ke komo ʻana a me ka maʻalahi o ka ʻili.

Hoʻohana ʻia ka PTFE ʻili no ka hoʻopaʻa ʻana i nā ʻano kumu ʻelua: ka hoʻoheheʻe ʻana i ka wela kiʻekiʻe (ʻoi aku ka ikaika o ka wā, 9.5 MPa ikaika me ka mea hoʻohui, akā hoʻokuʻu i nā kinoea ʻawaʻawa) a me ka sodium-naphthalene etching (5 MPa adhesion koke, haiki 24-48 hola puka makani, pōʻino ʻino). E koho ma muli o ka hoʻomalu kaiapuni a me ka hana lōʻihi vs.

ʻO ka hoʻomaʻemaʻe a me ka mālama pono e hoʻolōʻihi i ke ola o ka lole wela wela PTFE. E hoʻomaʻemaʻe ma hope o ka hoʻohana ʻana a ma hope o ka hoʻoluʻu. E hoʻohana i nā pulupulu palupalu, nā mea hoʻomaʻemaʻe kūʻokoʻa, a i ʻole ka waiʻona no nā ʻili. Mai hoʻohana i nā ʻakika/alkalis ikaika, bleach, a i ʻole nā ​​mea ʻoki metala. ʻO ka lubrication ʻaila silicone maʻamau e hōʻemi i ka ʻaʻahu. E hahai i kēia mau kuhikuhi no ka pale ʻana i ka pōʻino o ka uhi.

PTFE kiʻekiʻe-mehana lipine i ilihune kū'ē i ka ionizing radiation. Ma ka 1 kGy gamma wale nō, hāʻule ka ikaika tensile i ~25% o ke kumu. He kūpono wale ia no nā wahi haʻahaʻa haʻahaʻa (meaʻai/lāʻau sterilization <10 kGy). No ka ʻoihana nuklea a i ʻole ka mokulele, e hoʻohana i ka polyimide a i ʻole PEEK ma kahi.

ʻO ka hoʻāʻo ʻana i ka maikaʻi o ka emulsion PTFE e pili ana i ʻeono mau hōʻailona nui: paʻa maʻiʻo (60±2% no T/FSI 067-2021), pH (9.0-11.0), puʻupuʻu nui ʻāpana (laser diffraction / DLS), viscosity (12-30 mPa · s ma 25 ° C), kūpaʻa (centrifugal, thermal a me ke ʻano. Hoʻopili kēia alakaʻi i nā ʻano hoʻokolohua maʻamau no kēlā me kēia ʻāpana.

No ka PTFE kiʻekiʻe-mehana lipine ma lalo o ka lōʻihi-manawa immersion, ka PTFE substrate noho chemically inert, akā, o ka adhesive papa ka wahi nāwaliwali. Hoʻonāwaliwali ka wai i ka PSA silicone; ʻO ka wai paʻakai ka hoʻokē ʻino. No nā kinikona koʻikoʻi, koi ʻia nā fluorosilicone a i ʻole perfluoropolyether adhesives – a i ʻole ka lipine PTFE adhesive-free. ʻO ka pau ʻana o ka ikaika Peel a hiki i 40% ma hope o 48 mau hola i ka wai.
