ʻO ka lole wela kiʻekiʻe o ka PTFE (PTFE-coated fiberglass) ʻaʻole hiki ke hoʻololi maikaʻi ʻia no ka mea he palupalu maoli ke kumu fiberglass. ʻO nā lole ʻoi aku ka lahilahi (0.08mm) ola mau haneli a hiki i nā tausani o nā paʻi; māwae koʻikoʻi (>0.25mm) ma hope o nā kakini. ʻOi aku ka maikaʻi o ka ulana satin i ka ulana maʻamau. No ka hoʻomau ʻana i ke kuʻi ʻana, e noʻonoʻo i ka kiʻiʻoniʻoni PTFE paʻa a i ʻole ka lole i hoʻokumu ʻia i ka aramid.

ʻO ka lole wela kiʻekiʻe o ka PTFE (PTFE-coated fiberglass) i hoʻohana nui ʻia i ka paʻi textile a me ke kala ʻana no nā kāʻei paʻi wela (180-230 ° C), nā uhi pākaukau paʻi pale, nā kāʻei mesh maloʻo, nā kāʻei mīkini fusing, a me ka wili ʻōwili. Kāohi kona ʻili non-stick i ke koena o ka inika/adhesive, e hōʻemi ana i ka hoʻomaʻemaʻe downtime a hoʻomaikaʻi i ka maikaʻi o ka lole. Hiki i nā kāʻei hope ʻole ke hana mau.

ʻO ka PTFE kiʻekiʻe-mehana lole (PTFE-coated fiberglass) he mea kānana kānana maikaʻi no nā kūlana koʻikoʻi: ka hoʻohemo ʻana i ka lepo (cement, waste incineration, coal boilers a hiki i 260 ° C), corrosive wai kānana (acids, alkalis, aila), meaʻai / lāʻau hoʻomaʻemaʻe sterile kānana, a me HEPA cleanroom kānana. ʻAʻole hiki ke hoʻomaʻemaʻe maʻalahi ka ʻili non-stick. Loaʻa i nā māka membrane-laminated nā hoʻokuʻu haʻahaʻa loa.

PTFE kiʻekiʻe-mehana lole mālama maikaʻi uila insulation mai -180 ° C a hiki i 260 ° C: volume resistivity>10¹³ Ω·cm ma 200 ° C, dielectric paʻa paʻa ma 2.0-2.1. Ma luna o 260 ° C, PTFE palupalu, decomposes ma luna o 327 ° C, nalowale insulation mau loa. Ma lalo o 0 ° C, hoʻomaikaʻi ka insulation akā lilo ka uhi i palupalu. Noho i loko o 260°C no ka hana pono.

ʻO ka lole wela kiʻekiʻe o ka PTFE (PTFE-coated fiberglass) he mea kūpono ia no nā kāʻei conveyor meaʻai ma muli o kona kūpaʻa wela 260 ° C, -70 ° C hiki ke anuanu, non-stick surface, a me ka FDA compliance. Nā mea nui: nā umu bakena (biscuits, berena, pizza), nā mea lawe meaʻai palai, nā laina hoʻoluʻu candy, nā tunnels maloʻo, nā sila wela, a me ka ʻōwili wili. Hoʻemi i ka pau ʻole a me ka manawa hoʻomaʻemaʻe.

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.

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.

Hoʻohana ʻia ka lole kiʻekiʻe PTFE a me ka lole silikoni i ka lole fiberglass ma ke ʻano he kumu akā ʻokoʻa i nā mea uhi (PTFE resin vs silicone rubber). Ua ʻoi aku ka maikaʻi o ka PTFE i ka lāʻau ʻole, ka pale ʻana i ka ʻaʻahu, a me ke kūpaʻa kemika a hiki i 260°C. Hāʻawi ka lole silikoni i ka maʻalahi, ka hoʻokaʻawale uila, a me ke kūpaʻa ahi (a hiki i 230 ° C). E koho ma muli o kāu mea nui.

ʻO ka lole wela kiʻekiʻe ʻo PTFE (PTFE membrane material) he koho maikaʻi loa no ka hoʻolālā tensile. ʻO nā pōmaikaʻi nui: 30+ makahiki ke ola i waho, hoʻomaʻemaʻe iā ia iho (holoi ka lepo i ka wai ua), hoʻouna māmā māmā (6-13%), helu ahi papa A, a me ka ikaika like me ke kila ma lalo o 1.5 kg/m². Hoʻohana ʻia i nā kahua pāʻani, nā mokulele, a me nā hale kiʻiʻoniʻoni a puni ka honua.

Hāʻawi ka PTFE kiʻekiʻe-mehana lole i ke kūʻokoʻa kemika, kū i nā waikawa ikaika, alkalis, nā mea hoʻoheheʻe organik, a me nā kinoea corrosive. Hōʻike kēia ʻatikala i kāna mau mea kūʻokoʻa, nā palena (nā metala alkali hoʻoheheʻe, nā mea hana fluorinating ikaika), a me nā mea nui e like me ka mahana, ka noʻonoʻo, a me ke koʻikoʻi mechanical.
