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. Eia nō naʻe, ʻo ka haʻalulu ʻana i ka mea mai ka wela 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 (kūʻē i nā waikawa ikaika / alkalis), reactor a me nā linings tank (pale i ka corrosion metala, maʻalahi hoʻomaʻemaʻe), kānana ʻeke no ka corrosive flue kinoea (a hiki i 260 ° C), anti-corrosion hoʻonui ʻia nā hui 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 PTFE (PTFE-coated fiberglass) hāʻawi i ʻehā mau pōmaikaʻi ma ke ʻano he anti-corrosion lining: chemical inertness (kū'ē i ka aqua regia, alkalis ikaika, solvents), ākea ākea ākea (-70 ° C a 260 ° C mau, 350 ° C peak), dimensional stability (<0.5% elongation), a me ka non-stick elongation. 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.

Hāʻawi ka PTFE kiʻekiʻe-mehana lole i ʻeono mau pōmaikaʻi e like me ke kāʻei conveyor paʻi: non-stick surface (paʻi paʻi a me ka inika hoʻokuʻu maʻemaʻe), 260 ° C wela pale (maikaʻi maloʻo), dimensional paʻa (<0.5% elongation, kākau inoa pololei), kemika inertness (kū'ē i ka corrosive pastes), haʻahaʻa friction (smooth, anti-thickness), a me ka hana maʻamau. He kūpono no ka paʻi pale, paʻi kikohoʻe, a me nā noi hoʻoili wela.

Hoʻohui ka lole anti-static PTFE kiʻekiʻe-mehana i ka lāʻau ʻole, ka wela-pale (260°C), a me nā waiwai inert kemika o ka PTFE maʻamau me ka hana static-dissipative. Nā noi nui: ka hana uila (PCB lamination, ka hoʻohana ʻana i nā mea), PV module lamination (pale i ka ESD i ka pōʻino o nā cell solar), ka meaʻai a me ka hana lāʻau lapaʻau (ESD-safe baking liners), nā mea kanu kemika (anti-corrosion, anti-static ducting), a me nā ʻoihana textile/paʻi. He 10⁶–10⁹ Ω ke kū ʻana o ka ʻili.

PTFE ki'eki'e-mehana lole lawelawe ola 'oko'a dramatically ma ka noi. Hiki i ka lining anti-corrosion ke hoʻomau i 3+ mau makahiki (4x ʻoi aku ka lōʻihi ma mua o ka rubber). ʻO nā pā kīʻai meaʻai i nā mahina i hala me ka liʻiliʻi ʻino. Hoʻohana ʻia nā kāʻei conveyor ʻoihana mai ka hakakā ʻana. ʻO ka lamination PV (150°C, EVA contact) he ola haʻahaʻa. He pōkole ke ola o nā noi hoʻoheheʻe kaumaha (abrasive discs). ʻO nā kumu nui: ka mālama ʻana i ka mahana (noho ≤260°C), pale i nā ʻokiʻoki, hoʻomaʻemaʻe maʻamau, a me ka hoʻololi ʻana i ka manawa i ka wā e pohu a melemele paha.

ʻO ka PTFE kiʻekiʻe-mehana lole paʻa a hiki i 300 ° C, akā i loko o ke ahi e decompose a hoʻokuʻu i nā kinoea ʻawaʻawa loa: hydrogen fluoride (HF) (corrosive, pulmonary edema) a me perfluoroisobutylene (PFIB) (colorless, odorless, ~ 10x ʻoi aku ka ʻona ma mua o ka phosgene, ʻaʻohe antidote). ʻO ka carbon monoxide, nā koena PFOA, a me nā trace dioxins. ʻAʻole pono ka uhi ʻana o ka uahi maʻamau; e hoʻohana i ka mea hoʻomaha hanu ponoʻī (SCBA). Hoʻopaneʻe paha nā hōʻailona.

ʻO ka lole wela kiʻekiʻe o PTFE (PTFE-coated fiberglass) he mea kūpono ia no ka hoʻomehana microwave no ka mea e hoʻouna i nā microwave me ka ʻole o ka hoʻomoʻa ʻana i ka ikehu, kū i ka 260 ° C, a he ʻano lāʻau ʻole. Hoʻohana ʻia nā moena baking microwave, nā kāʻei mea hoʻomaloʻo hoʻomaloʻo ʻoihana, nā linings reactor no ka hoʻoheheʻe kemika, a a maʻamau; ikaika paʻa mua akā ʻaʻole kala ʻia me ka neʻe; ʻoi aku ka maikaʻi no nā paʻa paʻa, kiʻekiʻe.

ʻO ka lole wela kiʻekiʻe o ka PTFE (PTFE-coated fiberglass) ʻaʻole maikaʻi ke kūpaʻa ʻana no ka mea he maʻaʻole ke kumu o ka fiberglass substrate. 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.
