![Ka lole i uhi ʻia ʻo PTFE]( "PTFE Coated Fabric")
Ka hoʻomaopopo ʻana i ka lole i uhi ʻia ʻo PTFE a me kāna mau meaʻai-palekana
He aha ka PTFE Coated Fabric?
ʻO ka lole i uhi ʻia ʻo PTFE he mea i hoʻohui ʻia i ka ikaika a me ka maʻalahi o kahi lole kumu (pinepine fiberglass) me nā waiwai kūʻokoʻa o PTFE. Hoʻopili ʻia ka lole kumu me nā ʻāpana o ka PTFE, e hana ana i kahi paʻa paʻa ʻole. Loaʻa i kēia mea hou nā ʻano maikaʻi loa o nā ʻāpana ʻelua, ka hopena i kahi huahana ʻaʻole wela, inert kemika, a paʻakikī loa.
ʻO ke kaʻina hana hoʻopili e pili ana i ka hoʻopili ʻana i ka PTFE wai i ka lole me ka hoʻohana ʻana i nā ʻenehana kūikawā e like me ka uhi ʻana a i ʻole ka uhi ʻana. ʻO ka lole i uhi ʻia a laila e hana i kahi kaʻina hoʻōla wela kiʻekiʻe, kahi e hoʻopaʻa paʻa ai i ka PTFE i ka substrate. Hoʻokumu kēia i kahi ʻili maʻemaʻe, porous ʻole i kūpono no nā noi pili meaʻai.
Meaʻai-Pale Pono o PTFE
Loaʻa iā PTFE kekahi mau waiwai i kūpono loa ia no ka pili ʻana i ka meaʻai:
- ʻAʻole i paʻa i ka ʻili: ʻo ka PTFE haʻahaʻa haʻahaʻa o ka friction e pale i ka meaʻai mai ka hoʻopili ʻana, e maʻalahi ka hoʻomaʻemaʻe a mālama i nā kūlana maʻemaʻe.
- ʻAʻole ʻae ʻia ka PTFE me nā mea meaʻai, e hōʻoia ana ʻaʻole ia e hoʻololi i ka ʻono, ʻala, a i ʻole ke ʻano o ka meaʻai.
- Ke kū'ē i ka wela: Hiki i ka PTFE ke pale i nā mahana a hiki i ka 260 ° C (500 ° F) me ka hoʻohaʻahaʻaʻole, e kūpono ana i nāʻano kuke a me nā noi hana meaʻai.
- Non-porosity: ʻO ka maʻemaʻe a me ka porous ʻili o ka lole i uhi ʻia ʻo PTFE e pale i ka absorption o nā meaʻai a me ka bacteria, e hāʻawi ana i ka palekana o ka meaʻai.
ʻO ka ʻae ʻana o FDA a me nā lula pili i ka meaʻai
No ka lole i uhi ʻia ʻo Teflon i manaʻo ʻia he palekana no ka pili ʻana i ka meaʻai, pono ia e hoʻokō i nā lula koʻikoʻi i hoʻonohonoho ʻia e nā luna palekana meaʻai. Ma ʻAmelika Hui Pū ʻIa, mālama ka Food and Drug Administration (FDA) i kēia mau lula. Ho'āʻo ikaika ʻia nā lole i uhi ʻia ʻo PTFE i ʻae ʻia e FDA e hōʻoia i ka hoʻokō ʻana i nā koina kikoʻī no nā mea pili meaʻai.
ʻO ke kaʻina hana ʻae FDA e nānā i nā mea e like me:
- Hoʻohui kemika o ka uhi PTFE
- Loaʻa no ka neʻe ʻana o nā mea mai ka lole i ka meaʻai
- Paʻa ma lalo o nā ʻano wela a me nā kūlana pH
- Ke kū'ē i ka abrasion a me ka degradation
He mea nui e hoʻomaopopo ʻaʻole ʻae ʻia nā lole i uhi ʻia ʻo PTFE i FDA no ka pili ʻana i ka meaʻai. Ke koho ʻana i kahi lole i uhi ʻia ʻo PTFE no nā noi pili i ka meaʻai, e hōʻoia mau i kona kūlana ʻae FDA a me ka hoʻohana ʻana.
Nā noi o ka meaʻai-palekana PTFE i uhi ʻia i ka ʻoihana meaʻai
Lako Hana Mea ai
He koʻikoʻi koʻikoʻi ka lole i uhi ʻia ʻo PTFE i nā lako hana ʻai. ʻO kona mau waiwai non-stick a me ke kū'ēʻana i nā wela kiʻekiʻe he mea kūpono ia no nā kāʻei conveyor i nā hale kuke, nā mea kanu meaʻai, a me nā mea hana meaʻai'ē aʻe. Hoʻomaʻamaʻa kēia mau kāʻei i ka neʻe ʻana o nā huahana meaʻai ma o nā ʻano hana like ʻole me ka ʻole o ka pipili a waiho ʻana i nā koena.
Ma kahi o nā kāʻei conveyor, hoʻohana ʻia ka lole uhi PTFE i:
- Mea hoʻoheheʻe wai: E like me nā pā maloʻo e pale ai i ka ʻai ʻana mai ka pipili i ka wā o ka hoʻomaloʻo ʻana.
- Mea hoʻopili: E like me nā pepa hoʻokuʻu i nā mīkini hoʻopaʻa wela, e hōʻoia ana ʻaʻole pili nā mea hoʻopili i nā ʻili wela.
- Molds a me nā ʻano: No ka hana ʻana i nā huahana meaʻai me ka ʻole o ka pipiʻi ʻana, ʻoi aku hoʻi i ka hana confectionery a me ka hana ʻana i ka meaʻai.
Nā mea hana kālua a me ka kuke ʻana
Ua apo ka honua meaʻai i ka lole i uhi ʻia i ka PTFE no kāna mau waiwai lāʻau ʻole maikaʻi a me ke kūpaʻa wela. Loaʻa nā noi maʻamau:
- Nā pepa bakena a me nā laina laina: Hiki ke hoʻohana hou ʻia nā ʻāpana lole PTFE i hoʻopaʻa ʻia e hāʻawi i kahi ʻili lāʻau ʻole no ka kuke ʻana, e hōʻemi ana i ka pono o ka momona a me ka maʻalahi o ka hoʻomaʻemaʻe.
- Moena moena: ʻO nā moena lole i uhi ʻia ʻo PTFE e pale aku i ka hāʻule ʻana o ka meaʻai i loko o nā pahu kuʻi oiai e ʻae ana i kēlā mau hōʻailona grill i makemake nui ʻia.
- Nā laina umu: Mālama kēia i nā ʻili o ka umu mai nā ʻōpala a ʻoi aku ka maʻalahi o ka hoʻomaʻemaʻe ʻana.
ʻO ka hoʻohana ʻana i ka lole i uhi ʻia ʻo PTFE i loko o kēia mau noi ʻaʻole e hoʻomaikaʻi wale i ke kaʻina kuke a me ka kuke ʻana akā e hoʻolōʻihi i ke ola o nā mea kuke a me nā mea hana ma ka pale ʻana i ka kūkulu ʻana i ka meaʻai a me ka hōʻemi ʻana i ka lole a me ka waimaka.
Hoʻopili meaʻai a me ka waiho ʻana
ʻIke ʻia ka lole i uhi ʻia ʻo PTFE i nā noi i ka hoʻopili ʻana i nā meaʻai a me nā hoʻonā mālama pū kekahi:
- Nā laina hoʻokuʻu: I ka hana ʻana i nā lepili meaʻai adhesive a me ka hoʻopili ʻana, lawelawe ʻia ka lole i uhi ʻia ʻo PTFE ma ke ʻano he liner hoʻokuʻu, e ʻae ana i ka wehe maʻalahi o ke kākoʻo adhesive.
- Hiki ke hoʻohana hou ʻia ka meaʻai: Ma ke ʻano he ʻokoʻa eco-friendly i ka plastic wrap, hiki ke hoʻohana ʻia ka lole uhi PTFE e uhi a mālama i nā meaʻai.
- Hiki ke hoʻohana i nā meaʻai nui: ʻO nā ipu nui a i ʻole nā silo no ka mālama ʻana i nā waiwai maloʻo ke hoʻohana i nā laina lole i uhi ʻia e PTFE e pale aku i ka pipili a maʻalahi i ka hoʻomaʻemaʻe maʻalahi.
Hoʻohana kēia mau noi i nā waiwai kūʻokoʻa a me nā mea kemika o ka lole i uhi ʻia i ka PTFE e hoʻomaikaʻi i ka mālama ʻana i ka meaʻai a me ka maikaʻi o ka pale.
Nā Manaʻo palekana a me nā hana maikaʻi loa no ka hoʻohana ʻana i ka lole i uhi ʻia i ka PTFE me ka meaʻai
Nā palena wela a me ka hoʻohana kūpono
ʻOiai ʻo ka lole i uhi ʻia ʻo PTFE he mea wela loa ia, he mea koʻikoʻi ia e pili i kona mau palena wela e hōʻoia i ka palekana a mālama i kona kūpaʻa. ʻO ka hapa nui o nā lole i uhi ʻia ʻo PTFE i ka meaʻai palekana a hiki i 260°C (500°F), akā pono e hōʻoia i ka pae wela kikoʻī no kāu huahana.
Nā mea nui e hoʻomanaʻo:
- Hōʻalo i ka hōʻike ʻana i ka lole i uhi ʻia i ka PTFE i nā mahana ma mua o kona kiʻekiʻe i helu ʻia e pale i ka hōʻino ʻana o ka uhi.
- E hoʻohana i nā mea hana kūpono (ʻoi aku ka maikaʻi ʻole metala) e pale ai i ka ʻōpala a i ʻole ka hōʻino ʻana i ka ʻili PTFE.
- No ka hoʻomoʻa ʻana, e hōʻoia i ka holo ʻana o ka ea a puni ka lole i uhi ʻia ʻo PTFE e pale i ka wela.
E hahai mau i nā kuhikuhi a ka mea hana no nā palena wela a me nā ʻōlelo hoʻohana no ka mālama ʻana i ka palekana a me ka lōʻihi o kāu mau huahana i uhi ʻia i ka PTFE.
Hoʻomaʻemaʻe a mālama
ʻO ka hoʻomaʻemaʻe kūpono a me ka mālama ʻana i ka lole i uhi ʻia ʻo PTFE he mea nui ia no ka hōʻoia ʻana i ka palekana o ka meaʻai a me ka lōʻihi.
- Maʻemaʻe ma hope o kēlā me kēia hoʻohana: Holoi me ka wai mehana, kopa a holoi pono. E hōʻalo i ka hoʻohana ʻana i nā mea hoʻomaʻemaʻe abrasive a i ʻole nā holoi i hiki ke hōʻino i ka uhi PTFE.
- Wehe i nā koena paʻakikī: No ka meaʻai i kālua ʻia, e hoʻoinu i ka lole i ka wai mahana ma mua o ka holoi ʻana maʻemaʻe.
- Hoʻomaloʻo loa: E ʻae mau i ka lole i uhi ʻia i ka PTFE e maloʻo loa ma mua o ka waiho ʻana i mea e pale ai i ka ulu ʻana.
- E nānā mau: E nānā i nā hōʻailona o ka ʻaʻahu, e like me ka ʻili a i ʻole ka ʻili ʻana o ka uhi PTFE. E hoʻololi i ka lole inā ʻike ʻia kēlā pōʻino.
Ma ka hahai ʻana i kēia mau hana hoʻomaʻemaʻe a mālama ʻana, hiki iā ʻoe ke hōʻoia i ka palekana o kāu lole i uhi ʻia i ka PTFE no ka hoʻopili ʻana i ka meaʻai a hana maikaʻi loa no kahi manawa lōʻihi.
Hoʻoponopono i nā pilikia maʻamau a me nā manaʻo kuhihewa
ʻOiai ʻo kona palekana no ka pili ʻana i ka meaʻai, ke hoʻomau nei kekahi mau kuhi hewa e pili ana i ka lole i uhi ʻia i ka PTFE. E hoʻoponopono i kekahi mau pilikia maʻamau:
- Nā hopohopo PFOA: ʻOiai ua hoʻohana mua ʻia ka PFOA (perfluorooctanoic acid) i ka hana ʻana o PTFE, ua hoʻopau nā kaʻina hana hana hou i kāna hoʻohana. ʻAʻole PFOA nā lole i uhi ʻia i ka PTFE palekana i ka meaʻai.
- Hoʻoheheʻe Microplastic: ʻAʻole hoʻokahe nā lole i uhi ʻia PTFE kiʻekiʻe, mālama pono ʻia i ka microplastics i ka wā hoʻohana maʻamau. Hoʻopili paʻa ʻia ka uhi PTFE i ka lole kumu.
- Ke hoʻolele kemika: Ke hoʻohana ʻia i loko o kona mau palena wela, ʻaʻole hoʻolele ka lole i uhi ʻia i ka PTFE i nā meaʻai. ʻO kona inertness kemika kekahi o kāna mau hiʻohiʻona palekana.
He mea nui e hoʻokaʻawale i waena o ka PTFE a me nā fluoropolymers ʻē aʻe i loaʻa nā waiwai like ʻole. E nānā mau i nā noiʻi ʻepekema a me nā ʻae hoʻoponopono i ka wā e loiloi ai i ka palekana o nā lole i uhi ʻia ʻo PTFE no ka pili ʻana i ka meaʻai.
Ka hopena
ʻO ka lole i uhi ʻia ʻo PTFE, ke hana pono ʻia a hoʻohana ʻia, palekana maoli no ka pili ʻana i ka meaʻai. ʻO kāna mau waiwai kūʻokoʻa e lilo ia i mea waiwai nui i nā noi ʻoihana meaʻai like ʻole, mai ka hana ʻana i nā mea hana a hiki i ka kuke ʻana a me nā mea hana kuke. Ma ka hoʻomaopopo ʻana i kāna mau hiʻohiʻona, e pili ana i nā alakaʻi hoʻohana, a me ka mālama pono ʻana, hiki iā ʻoe ke leverage i nā pono o ka PTFE i uhi ʻia i ka lole ʻoiai e hōʻoiaʻiʻo ana i ka palekana o ka meaʻai. E like me nā mea pili meaʻai, he mea koʻikoʻi ka hoʻohana ʻana i nā huahana i ʻae ʻia e FDA a hahai i nā ʻōlelo aʻoaʻo mea hana e hoʻonui ai i ka palekana a me ka hana.
