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.

No ka hapanui o nā kaiapuni kemika, paʻa mau ka lole PTFE a hilinaʻi.

Pono ka PTFE emulsion impregnation o ka lole fiberglass i nā mea kōkua like ʻole e hoʻokō i ka uhi ʻaʻahu, adhesion ikaika, a me nā wahi kīnā ʻole. ʻO nā mea hoʻohui koʻikoʻi: nā mea hoʻomaʻemaʻe (e hoʻemi i ka neʻe ʻana o ka ʻili, hoʻomaikaʻi i ke komo ʻana), nā mānoanoa (ka mālama ʻana i ka viscosity a me ke kaumaha o ka uhi ʻana), pH regulators (stabilize emulsion ma ka pH 9-10), silane coupling agents (hoʻonui i ka pili ʻana i ke aniani), nā mea hana kiʻiʻoniʻoni (PFA / FEP no ka sintering), nā mea hoʻopiha hana (nā pale lole, conductivity) maloo).

He ʻokoʻa ka lole fiberglass i hoʻonui ʻia (nui ka lole wili) mai ka lole fiberglass maʻamau i ka hana yarn. Ma o ke kiʻekiʻe-press air jet lapaʻau, hoomau aniani filaments ua kaawale, crimped, a fluffed i voluminous, pulupulu-like wili. Hoʻokumu kēia i ka lole ʻoi aku ka mānoanoa a me ka palupalu me ka insulation thermal maikaʻi loa (nā ʻāpana ea i hoʻopaʻa ʻia), ʻoi aku ka maikaʻi o ka conformability, ʻoi aku ka maikaʻi o ka kānana ʻana, a me ka hoʻomaikaʻi ʻana i ka waimaka/ke kūpaʻa - ma ke kumu kūʻai o ka ikaika tensile haʻahaʻa. Hoʻohana ʻia no nā ʻeke wela kiʻekiʻe, nā paipu paipu, nā ʻeke kānana, a me nā sila umu.

ʻO ka lole wela kiʻekiʻe o ka PTFE (PTFE-coated fiberglass) ʻaneʻane inert kemika, akā ʻo kekahi mau mea ke kumu i ka pala ma lalo o nā kūlana kikoʻī. Hoʻouka pololei ʻia ka PTFE me nā metala alkali i hoʻoheheʻe ʻia (sodium, potassium), nā mea hana fluorinating ikaika (F₂, ClF₃) ma nā wela kiʻekiʻe, a me nā alkalina ikaika i hoʻoheheʻe ʻia ma luna o 300°C. Hiki ke ʻino ʻole i ka wā e komo ai ka waika hydrofluoric (HF), alkalis concentrated wela, a i ʻole waika phosphoric wela i nā hemahema o ka uhi ʻana a hoʻouka i ka substrate fiberglass. No ka lawelawe kemika koʻikoʻi, e hoʻohana i ke kiʻi PTFE maʻemaʻe me ka fiberglass.

ʻO ka lole wela kiʻekiʻe o PTFE (PTFE-coated fiberglass) he kūpaʻa haʻalulu maikaʻi loa i loko o kāna mau hana maʻamau o -70°C a 260°C. Hiki iā ia ke ʻae i ka holo kaʻa uila wikiwiki, e laʻa, ka neʻe ʻana mai kahi -50°C paʻukū a i kahi paʻi wela 260°C. ʻO nā māka maikaʻi loa e ola i ka hoʻolili koke ʻana mai 260 ° C i ka wai 10 ° C.
