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 ka 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 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). Hiki ke lohi nā hōʻailona.

Hoʻohana ʻia nā mea hoʻopau ʻili i ka lole fiberglass ma mua o ka uhi ʻana o ka PTFE he mea koʻikoʻi no ka hana ʻana o ka lole wela kiʻekiʻe PTFE. Hoʻokumu nā mea hoʻopili organosilane i nā alahaka molekala ma waena o ke aniani aniani a me ka PTFE organik, e hoʻonui ana i ka ikaika peel mai <2 N / cm a 4-8 + N / cm. Hoʻonui ka lapaʻau kūpono i ka pale wela (260°C+), ka hana dielectric, a me ke kūpaʻa kemika. ʻO ka lole i mālama ʻole ʻia e alakaʻi i ka delamination, bubbling, a me ke ola lawelawe pōkole.

ʻO ka hoʻomaʻemaʻe a me ka mālama pono e hoʻolōʻihi i ke ola o ka lole wela wela PTFE. E hoʻomaʻemaʻe ma hope o ka hoʻohana ʻana a ma hope o ka hoʻoluʻu. E hoʻohana i nā pulupulu palupalu, nā mea hoʻomaʻemaʻe kūʻokoʻa, a i ʻole ka waiʻona no nā ʻili. Mai hoʻohana i nā ʻakika/alkalis ikaika, bleach, a i ʻole nā ​​mea ʻoki metala. ʻO ka lubrication ʻaila silicone maʻamau e hōʻemi i ka ʻaʻahu. E hahai i kēia mau kuhikuhi no ka pale ʻana i ka pōʻino o ka uhi.
