No ka PTFE kiʻekiʻe-mehana lipine i hoʻohana ʻia i nā noi abrasive sliding friction, ʻaʻole lawa ka maʻamau non-stick a me ka pale wela. Nā pae koho kiʻi: Taber abrasion poho (<15 mg/1000 cycles), hoʻopiha ʻia i hoʻololi ʻia ka uhi PTFE (carbon/graphite/MoS₂), ʻikepili palena PV, ikaika substrate (≥200 N/cm), a me ka ʻili o ka ʻili (Ra 0.2-0.4 μm). ʻO ka pale lihi kūpono a me ka hoʻopaʻa piha ʻana he mea koʻikoʻi no ka lōʻihi.

Hoʻohana ʻia nā mea hoʻopau ʻili i ka lole fiberglass ma mua o ka uhi ʻana o ka PTFE he mea koʻikoʻi no ka hana ʻana o ka lole wela kiʻekiʻe PTFE. Hoʻokumu nā mea hoʻopili organosilane i nā alahaka molekala ma waena o ke aniani aniani a me ka PTFE organik, e hoʻonui ana i ka ikaika peel mai <2 N / cm a 4-8 + N / cm. Hoʻonui ka lapaʻau kūpono i ka pale wela (260°C+), ka hana dielectric, a me ke kūpaʻa kemika. ʻO ka lole i mālama ʻole ʻia e alakaʻi i ka delamination, bubbling, a me ke ola lawelawe pōkole.

Hoʻoholo ʻia ka hana lole lole wela kiʻekiʻe o PTFE. Hoʻonui ka mānoanoa kiʻekiʻe i ka ikaika tensile a me ka maʻalahi o ka ʻili akā e hōʻemi i ka ikaika o ka waimaka (hoʻohuli U-curve), ka maʻalahi, a me ke komo ʻana o ka uhi. ʻO ke kaulike maikaʻi loa e hoʻopaʻa i ke komo ʻana, ka pale ʻana i ka waimaka, ka maʻalahi, a me ka pau ʻana o ka ʻili. ʻO ka haʻahaʻa haʻahaʻa kūpono i ka dynamic bending; kiʻekiʻe kiʻekiʻe no ka non-stick a me ka insulation.

ʻO ka pāpaʻi PTFE he paʻakai paʻakai kūʻokoʻa (ka wai absorption <0.01%). Eia nō naʻe, pili ka hana lipine holoʻokoʻa i ke ʻano adhesive: silicone PSA kū i nā kaiapuni moana (500-1000h hoʻāʻo paʻakai,> 80% paʻa ʻili); hāʻule ka PSA acrylic. ʻO ka hoʻomaʻamaʻa ʻana i ka ʻili kūpono, ka hoʻohana ʻana i ka bubble-free, a me ka hoʻopaʻa ʻana i ka lihi me ka silikon sealant he mea koʻikoʻi no ka hilinaʻi lōʻihi ma nā paepae a me nā moku.

Kalendering - kaomi ʻana i ka lole i uhi ʻia i ka PTFE ma waena o nā wili aniani wela ma 360-380 ° C - hoʻololi nui i ka morphology ili, hoʻokuʻu i nā waiwai, impermeability, a me ka hana mechanical. Hoʻemi ia i ka roughness mai Ra 0.5-1.0 μm a i <0.05 μm, hoʻopaʻa i nā pinholes, hoʻomaikaʻi i ka pale ʻana, akā hoʻemi i ka ikaika o ka waimaka a me ka maʻalahi. Pono no ka hoʻokuʻu ʻana i nā liner a me ka hoʻokaʻawale uila.

ʻO ka hiʻohiʻona ulana fiberglass - maʻalahi, twill, a i ʻole satin - pili nui i ka PTFE mau mea wela wela. Hāʻawi ka ulana satin i ka ikaika haʻalulu kiʻekiʻe (2-3x paʻa) 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 like ʻana o ka uhi ʻana o ka lole wela kiʻekiʻe PTFE e nā kumu ʻehā: ka hoʻokumu ʻana o ka uhi (ka nui o ka particle 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 ke kaiapuni hana (20-25% R, <60). ʻO ke kaʻina hana hoʻohui ʻia ʻo Dip + blade e kaulike i ke komo ʻana a me ka maʻalahi o ka ʻili.
