Hana ʻia ka lole kiʻekiʻe PTFE ma o ka impregnation hoʻokahi wale nō (hoʻokahi pass: wikiwiki, haʻahaʻa, ʻili lahilahi, ʻili ʻili me nā pinholes) a i ʻole multi-dip impregnation (2-3+ hele: paheʻe, paʻa, pinhole-free coating, PTFE maʻiʻo 50-70%, hana premium, kumukūʻai kiʻekiʻe). Hoʻopili ʻia ka pahu hoʻokahi i nā pahu haʻahaʻa haʻahaʻa, nā moena manawaleʻa, a me nā mea hanu. Pono ʻia ka multi-dip no nā pepa bakena meaʻai, nā kāʻei conveyor non-stick, nā substrate kaapuni alapine kiʻekiʻe, nā laina kemika, a me nā membrane kūkulu hale.

PTFE kiʻekiʻe-mehana lole ili lapaʻau wawahi kemika inertness no ka hoʻopaʻa 'ana/paʻi. ʻEhā mau ʻano: etching kemika (sodium-naphthalene, ikehu ʻili 20→40-50 dyn/cm, papa ʻeleʻele mau, micro-porous structure), lapaʻau plasma (nano-roughening, grafting hui hana, puka aniani pōkole), mālama corona (kiʻiʻoniʻoni, palaho wikiwiki, palena hohonu), a me ka lāʻau laser (ka micro-patterning, controlled carbonization). ʻO nā ʻano hana a pau e hoʻopaʻa kino a hoʻokomo i nā hui polar (C=O, -OH, -COOH) e hiki ai ke hoʻopaʻa paʻa.

ʻO ka hoʻomaʻemaʻe waiwai kumu ke kumu kumu o ka maikaʻi o ka lole kiʻekiʻe o ka PTFE. ʻO nā mea haumia (nā mea hoʻomaka, surfactants, ion metala, nā mea hoʻomāinoino ʻia) ke kumu o ka hoʻohaʻahaʻa ʻana i ka wela (bubbles, blistering ma luna o 260°C), nā ʻili lāʻau ʻole like ʻole (adhesion anchor points), hoʻemi ʻia ka insulation uila (dielectric loss, low breakdown voltage), nāwaliwali ka ikaika mechanical (stress concentration, pohā), ʻO nā mea maka maʻemaʻe kiʻekiʻe e hōʻoia i ka FDA-compliant, lōʻihi ke ola, kiʻekiʻe-hana PTFE lole.

Pono ka hoʻopaʻa ʻana o ka lole fiberglass PTFE-coated i ka manawa paʻa ma 370-400°C. Nā kapuahi mau: 30-90s (ka lahilahi) a 3-5+ min (mānoanoa). Nā kapuahi pahu: 5-15 min. ʻO ka hoʻoheheʻe ʻia ʻana ma lalo o ke kumu o ka opaque, nā ʻili ʻōpala e ʻili; ʻO ka nui o ka sintering ke kumu o ka melemele, brittleness, a me ka hoʻokuʻu kinoea fluoride ʻona. Kaʻina hana: hoʻohana i nā mea nānā wela o ka umu ahi, hana i ka nānā maka (semi-transparent, flexible), a hana i nā hoʻokolohua huki lipine. E hōʻoia mau i ka piha-mānoanoa like like.

Pono ka lole wela o ka PTFE i ka mālama pono ʻana e hōʻoia i ka palekana a me ka lōʻihi. ʻO nā mea nui: mai ʻoi aku ma mua o 260°C (ma luna o 320°C e hoʻokuʻu i nā uahi ʻawaʻawa), e pale i nā peʻe ʻoi (ka uhi ʻia nā māwae, e hōʻike ana i ka fiberglass), ʻaʻohe hoʻomaʻemaʻe abrasive (hoʻopōʻino ka huluhulu kila i ka ʻili ʻole), mālama i ka hoʻonui ʻana i ka wela (e pale i ka haehae ʻana), a hoʻololi i ka wā i pohū a ihi ʻia. E kūʻai i ʻōwili ʻia, mamao mai UV. E hoʻohana i nā mīkina lima pale wela i ka wā e lawelawe ai.

PTFE kiʻekiʻe-mehana lole he coefficient o thermal hoʻonui (CTE) o 30-60 ppm/°C (warp/weft) - oi aku mamua o fiberglass wale akā, emi loa ma mua o maemae PTFE (100-200 ppm/°C). Loaʻa ka PTFE i nā loli nui (1-2%) ma 19°C a me 30°C. No ka pale ʻana i ka hoʻopaʻa ʻana, ka uhae ʻana, a me ka delamination: hoʻolālā i nā ʻae no ka hoʻonui manuahi, e pale i ka neʻe ʻana ma o ka hoʻololi ʻana o ka pae, hoʻohana i nā tensioners ʻakomi ma nā kāʻei conveyor, a hoʻopili i ka hoʻolālā overlap anti-buckling. Pono ka nānā mau ʻana no ke kahe anu.

ʻO ka PTFE kiʻekiʻe-mehana lole moena bakena hāʻawi i ʻehā mau pōmaikaʻi: hana ʻole (ʻaʻohe aila a palaoa paha, hoʻokuʻu maʻemaʻe nā pastries palupalu), ākea ākea ākea (-70 ° C a 260 ° C, palekana no ka umu i ka paʻukū), hiki ke hoʻohana hou ʻia (nā kaukani o nā pōʻai, maʻalahi e hoʻomaʻemaʻe), a hiki i ka hoʻokele wela (pale i ke ahi, kaulike browning). ʻOi aku ka maikaʻi o nā moena silicone me ka hoʻololi wela a ʻoi aku ka maikaʻi o ka ʻili.

He mea nui ka PTFE kiʻekiʻe-mehana lole i ka ʻoihana interlining lole. Nā mea nui: nā kāʻei conveyor pau ʻole no nā mīkini fusing mau (pale i ka hoʻoheheʻe ʻana i ka hoʻoheheʻe wela, ka lawe ʻole ʻana i ka wrinkle), ka uhi ʻole a me ka lole pale no nā paʻi wela paʻa (pale i nā platens mai ka hoʻopili ʻia ʻana), nā kāʻei conveyor no nā laina dot paste / pauda (mālama i ka paʻa paʻa ʻana i nā pahu hoʻopaʻa i ka wā o ka uhi ʻana). ʻO ka mānoanoa mai ka 0.13mm (padding māmā) a i ka 0.55mm (nā kāʻei conveyor kaumaha).

Loaʻa ʻia ka lole PTFE anti-static ma o nā ʻano kumu ʻelua: ka uhi ʻana i ka doping (ka hui pū ʻana i nā mea hoʻopiha conductive e like me ke kalapona ʻeleʻele i loko o ka emulsion PTFE, e hana ana i kahi pūnaewele percolation ma ke koʻikoʻi koʻikoʻi) a me ka ulana substrate (hoʻokomo ʻana i nā kaula conductive i loko o ka lole fiberglass). Hoʻomalu ʻia ka resistivity o ka ʻili ma 10⁵–10⁹ Ω. ʻO ke kumu: hana i kahi ala conductive e hoʻokahe koke i nā uku static, e pale ana i ka hōʻiliʻili ʻino. Pono ke kahua no ka hana pono.

ʻO ka lole wela kiʻekiʻe o ka PTFE (PTFE-coated fiberglass) hāʻawi i ke kūʻokoʻa kemika, kū i nā waikawa concentrated (me ka aqua regia), nā alkali ikaika (ma ka lumi wela), nā mea hoʻoheheʻe kūlohelohe, a me nā mea hoʻoheheʻe. Hoʻokoe: hoʻoheheʻe ʻia nā metala alkali a me nā pūhui halogen wela kiʻekiʻe e hoʻouka i ka PTFE. Hōʻike ka pōʻino i ka fiberglass i ka waika hydrofluoric a me nā alkalina wela. ʻO ka mahana ma luna o 260 ° C e hōʻemi i ke kū'ē. No ka hapanui o nā kaiapuni kemika, paʻa loa ka lole PTFE a hilinaʻi.
