Ka hoʻomaopopo ʻana i ke ʻano a me nā ʻano o ka PTFE Coated Fabrics
ʻO ke ʻano o nā lole i uhi ʻia e PTFE
ʻO nā lole i uhi ʻia ʻo PTFE he mea kumu, ʻo ka fiberglass maʻamau, i uhi ʻia me ka polytetrafluoroethylene (PTFE). ʻO kēia hui kūʻokoʻa ka hopena i kahi mea i hoʻoili i ka ikaika o ka fiberglass a me ka inertness kemika o PTFE. Hāʻawi ka fiberglass substrate i ka ikaika tensile maikaʻi a me ke kūpaʻa dimensional, ʻoiai ka uhi ʻana o ka PTFE e hāʻawi i nā waiwai non-stick, kūpaʻa kemika, a hoʻonui i ka pale wela.
ʻO ke kaʻina hana uhi e pili ana i ka hoʻopili ʻana i nā papa he nui o PTFE i ka substrate fiberglass. Hiki ke hoʻopilikino ʻia ka mānoanoa a me ka helu o nā papa e hoʻokō i nā koi kikoʻī. Loaʻa paha i kekahi mau lole ka ʻike PTFE mai 15% no nā noi porous a i 85% no nā huahana i uhi nui ʻia. ʻO kēia versatility e hiki ai i nā mea hana ke hoʻololi i nā waiwai o ka lole no nā ʻano hana ʻoihana a me nā ʻoihana.
Waiwai wela o ka PTFE
ʻO PTFE, ka mea koʻikoʻi i loko o kēia mau lole i uhi ʻia ʻo Teflon , ke kaena nei i nā waiwai wela. He wahi hehee kona ma kahi o 327°C (620°F) a hiki ke malama i kona mau waiwai kino ma na wela a hiki i 260°C (500°F). He mea koʻikoʻi kēia kūpaʻa wela kiʻekiʻe i nā noi pale ahi, no ka mea e hiki ai i ka lole ke mālama i kona kūpaʻa a me nā ʻano pale ʻoiai ke ʻike ʻia i ka wela wela.
Eia kekahi, he haʻahaʻa haʻahaʻa ka wela o ka PTFE, ʻo ia ka mea ʻaʻole hiki ke hoʻololi i ka wela. Hāʻawi kēia waiwai i kona pono ma ke ʻano he pale wela, e kōkua ana e hoʻolōʻihi i ka hoʻoili wela i nā kūlana ahi. He kiʻekiʻe nō hoʻi ka mana wela kikoʻī o ka mea, hiki iā ia ke komo i ka nui o ka ikehu wela ma mua o ka piʻi nui ʻana o kona wela.
Paʻa Kemika a me ka Haʻahaʻa Flammability
ʻO kekahi o nā mea koʻikoʻi e kōkua ana i ke kū ʻana o ke ahi o nā lole i uhi ʻia ʻo PTFE, ʻo ia ka paʻa kemika o PTFE. ʻO nā paʻa kalapona-fluorine ikaika i ka PTFE e kūpaʻa loa i nā hopena kemika, me ka oxidation. ʻO kēia kūpaʻa ʻo ia ka PTFE ʻaʻole e kākoʻo koke i ka puhi ʻana, e hoʻolilo iā ia i mea kūpaʻa i ka lapalapa.
Ke ʻike ʻia i ke ahi, makemake ʻo PTFE i ka char ma mua o ke ahi. Hoʻokumu kēia kaʻina hana charring i kahi papa pale e pale hou aku i ka laha ʻana o ka lapalapa a kōkua i ka mālama pono ʻana i ke ʻano o ka lole. ʻO ka haʻahaʻa haʻahaʻa o ka PTFE, i hui pū ʻia me kona hiki ke hoʻopau iā ia iho, lilo ia i mea koho maikaʻi loa no nā noi i mea nui ka palekana ahi.
Nā Kūlana Kū'ē ahi a me ka ho'āʻoʻana no nā lole i uhiʻia e PTFE
Nā Kūlana Kūʻokoʻa Ke ahi
ʻO nā lole i uhi ʻia ʻo PTFE e hoʻāʻo ʻia e hōʻoia i ka hoʻokō ʻana i nā kūlana pale ahi. ʻOkoʻa kēia mau maʻamau ma muli o ka noi i manaʻo ʻia a me kahi wahi ʻāina. ʻO kekahi o nā pae honua i ʻike nui ʻia:
- ASTM E84: Keʻano ho'āʻo maʻamau no nā hiʻohiʻona puhi ahi o nā mea hale
- EN 13501-1: Hoʻohālikelike ahi o nā huahana kūkulu a me nā mea hale
- UL 94: Kūlana no nā hoʻāʻo ʻana no ka hiki ʻana o ke ahi o nā mea palaki no nā ʻāpana i nā mea hana a me nā mea hana.
Hoʻohālikelike kēia mau maʻamau i nā ʻano like ʻole o ka hana ahi, me ka laha ʻana o ka lapalapa, ka ulu ʻana o ka uahi, a me ke kū ʻana i ke ahi. Hana maikaʻi loa nā lole i uhi ʻia ʻo PTFE i kēia mau hoʻāʻo ma muli o ko lākou mau waiwai kū i ke ahi.
Nā ho'āʻo pale ahi kūikawā
No ka loiloi ʻana i ke kūpaʻa ahi o nā lole i uhi ʻia i ka PTFE a i ʻole ka lole i uhi ʻia ʻo PTFE , nā mea hana a me nā keʻena hoʻokolohua kūʻokoʻa e hana i nā ʻano hoʻokolohua kikoʻī. Hiki i kēia mau mea ke komo:
- Vertical Flame Test: E ana i ka hiki o ka lole ke kinai iā ia iho a pale i ka hoʻolaha ʻana o ka lapalapa.
- Ho'āʻo ʻo Radiant Heat Resistance: E loiloi i ka hana o ka mea i ka wā e ʻike ai i nā kumu wela wela
- Ho'āʻo ʻo Limiting Oxygen Index (LOI): Hoʻoholo i ka haʻahaʻa haʻahaʻa o ka oxygen e pono ai e kākoʻo i ka puhi ʻana.
Hāʻawi kēia mau ho'āʻo i ka ʻikepili koʻikoʻi e pili ana i ka hana ʻana o nā lole uhi PTFE ma lalo o nā hiʻohiʻona ahi like ʻole, e kōkua ana i nā ʻenekinia a me nā mea hoʻolālā e koho i nā mea kūpono loa no nā noi kikoʻī.
