Hana ʻia ka lole kiʻekiʻe PTFE ma o ka impregnation hoʻokahi-hoʻokahi (hoʻokahi pass: wikiwiki, haʻahaʻa, ʻili lahilahi, ʻili ʻili me nā pinholes) a i ʻole impregnation multi-dip (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 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 makani pōkole), mālama corona (kiʻi ʻoniʻoni, 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, nā ion metala, nā mea hoʻomāinoino ʻia) ke kumu o ka hoʻohaʻahaʻa ʻana i ka wela (bubbles, blistering ma luna o 260°C), nā ʻaoʻao lāʻau ʻole (adhesion anchor point), hoʻemi ʻia ka insulation uila (dielectric loss, haʻahaʻa haʻahaʻa voltage), nāwaliwali ka ikaika mechanical (stress concentration, māwae), 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 PTFE e mālama pono i ka palekana a me ka lōʻihi. ʻO nā mea nui: ʻaʻole ma mua o 260°C (ma luna o 320°C e hoʻokuʻu i nā ʻawaʻawa 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 lāʻau ʻole), mālama i ka hoʻonui ʻana i ka wela (pale i ka haehae ʻana), a hoʻololi i ka wā i pohu 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.

ʻO ka PTFE kiʻekiʻe-mehana lole he coefficient o ka hoʻonui wela (CTE) o 30-60 ppm / ° C (warp / weft) - ʻoi aku ka kiʻekiʻe ma mua o ka fiberglass wale nō akā haʻahaʻa loa ma mua o ka PTFE maʻemaʻe (100-200 ppm / ° C). Loaʻa ka PTFE i nā hoʻololi o ka leo (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, pale i ka hoʻopaʻapaʻa ʻana ma o ka hoʻololi ʻana o ka pae, hoʻohana i nā tensioners ʻakomi ma nā kāʻei conveyor, a kau 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 ʻole no nā mīkini fusing mau (pale i ka hoʻoheheʻe ʻana i ka hoʻoheheʻe wela, ka lawe ʻole ʻana i ka wrinkle), ka uhi paʻa ʻole a me ka lole pale no nā paʻi wela paʻa (pale i nā papa mai ka hoʻopili ʻia ʻana), nā kāʻei conveyor no nā laina hoʻopaʻa dot/powder coating (mālama paʻa paʻa ʻana i nā kiko i ka wā o ka hoʻopili ʻana), a maloʻo. 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, me ka kū ʻana i nā waikawa concentrated (me ka aqua regia), nā alkali ikaika (ma ka lumi wela), nā mea hoʻoheheʻe organik, 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 mau ka lole PTFE a hilinaʻi.
