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.

ʻO ka maloʻo ʻana he hana koʻikoʻi i ka PTFE kiʻekiʻe-mehana lole hana. ʻO nā hemahema maʻamau: ka māhā (ka maloʻo wikiwiki loa, ka ʻili ʻili o ka ʻili), ka neʻe ʻana o ka uhi (neʻe nā ʻāpana i ka ʻili, nāwaliwali ka paʻa o loko), nā pinholes/blisters (trapped air or steam), nā kiko keʻokeʻo a me ka chalking (surfactant migration or incomplete fusion), yellowing/coking (ka wela nui o nā mea hoʻohui), delamination (pehuʻi ʻana o ke kaumaha), ʻoi aku ka nui o ke kaua ka emi ʻana), maloʻo ka ʻili akā pulu o loko (ka pahele ʻili i ka maka), a me nā ʻaoʻao mānoanoa (ka hopena o ke apo). Hoʻopili ʻia nā hoʻonā i nā profile maloʻo i hoʻomalu ʻia, ka ea kūpono, a me ka hoʻomaʻamaʻa mua ʻana i ka substrate.

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 / hoʻololi kūʻē - 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 maʻemaʻe maʻemaʻe ke kumu o ka PTFE kiʻekiʻe-mehana lole hana. ʻO ka emulsion PTFE maʻemaʻe kiʻekiʻe (ʻaʻohe ion metala, ʻaʻohe koena haʻahaʻa-molecular-kaumaha) e hōʻoia i ka pale ʻana i ka wela (ʻaʻohe melemele a hiki i 260 ° C), paʻa paʻa ʻole, a me ka ikaika dielectric kiʻekiʻe. No ka fiberglass, alkali-free E-glass (Na₂O <0.8%) mālama i ka ikaika a me ka insulation ma nā wela kiʻekiʻe; ʻO ke aniani waena/kiʻekiʻe-alkali e hoʻohaʻahaʻa. ʻO ka hoʻopau piha ʻana i nā mea ulana nui e pale i ka carbonization a me ka delamination. Hoʻopili pololei ka maʻemaʻe i ke ola lawelawe, ka mālama ʻana i ka meaʻai, a me ka hilinaʻi uila.

ʻO ka lole wela kiʻekiʻe 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 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 ka 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 kaʻa wela, e laʻa, ka neʻe ʻana mai kahi -50°C i kahi paʻi wela 260°C. ʻO nā māka maikaʻi loa e ola i ka hoʻolili koke ʻana mai 260 ° C i 10 ° C wai. Eia naʻe, ʻo ka haʻalulu ʻana i ka mea mai nā mahana ma luna o 300°C (kokoke i ka helu heheʻe o 327°C o PTFE) e hoʻomaka koke i ka pohā a me ka delamination. Hāʻawi ka fiberglass substrate i ke kūpaʻa dimensional; ʻO ka uhi PTFE ka mea palena.

Hoʻohana nui ʻia ka lole kiʻekiʻe o ka PTFE i ka ʻoihana kemika no ʻehiku mau noi nui: flange gaskets a me nā paipu linings (kū'ē i nā waikawa ikaika / alkalis), reactor a me nā linings tank (pale i ka corrosion metala, maʻalahi ka hoʻomaʻemaʻe), kānana ʻeke no ka corrosive flue kinoea (a hiki i 260 ° C), anti-corrosion hoʻonui ʻia no ka hoʻokuʻu ʻana i nā ducts. a me nā mea hoʻopuʻi uila / wela wela. Loaʻa nā māka FDA a me UL.

ʻO ka lole wela kiʻekiʻe o ka PTFE (PTFE-coated fiberglass) hāʻawi i ʻehā mau pono nui ma ke ʻano he anti-corrosion lining: chemical inertness (kū'ē i ka aqua regia, ikaika alkalis, solvents), ākea ākea ākea (-70 ° C a 260 ° C mau, 350 ° C peak), dimensional stability (<0.5% elongation), a me ka non-stick elongation (ka hoʻomaʻemaʻe ʻana i ka lepo). Hoʻohana ʻia i loko o nā paipu kemika, nā hale kiaʻi desulfurization, nā pahu pickling, a me nā lako meaʻai/pharma. Loaʻa nā māka FDA.
