Ua like anei ka PTFE me ka polyester?

Pehea e hoʻohana ʻia ai ʻo PTFE i ka ʻoihana meaʻai?

He nui nā noi o ka PTFE (polytetrafluoroethylene) i ka ʻoihana meaʻai, ʻo ia hoʻi ma muli o kona kūpaʻa kemika maikaʻi loa, ke kūpaʻa wela kiʻekiʻe, ka ʻaʻole e pipili a me ke koina haʻalulu haʻahaʻa. Eia nā noi nui o ka PTFE i ka ʻoihana meaʻai: 

1. Uhi ʻana i nā lako hana meaʻai

Hoʻohana nui ʻia ka uhi PTFE i ka uhi ʻana a me ka mālama ʻana i ka ʻili o nā lako hana meaʻai. ʻO kona ʻano pipili ʻole e pale i ka pipili ʻana o ka meaʻai i ka ʻili o nā lako i ka wā o ka hana ʻana, a laila e hoʻomaʻalahi ai i ke kaʻina hana hoʻomaʻemaʻe a hoʻomaikaʻi i ka pono o ka hana ʻana. No ka laʻana, i nā lako e like me nā umu, nā mokuahi, a me nā mea hui, hiki i ka uhi PTFE ke hōʻoia i ka pipili ʻole ʻana o ka meaʻai i ka wā o ka hana ʻana i ka mahana kiʻekiʻe me ka mālama ʻana i ka pono a me ka maikaʻi o ka meaʻai. 

2. Nā kāʻei hoʻoili a me nā kāʻei hoʻoili

Hoʻohana pinepine ʻia nā kāʻei conveyor i uhi ʻia me ka PTFE a me nā kāʻei conveyor i ka hana ʻana i ka meaʻai i hana nui ʻia, e like me ka kuke ʻana a me ka lawe ʻana i nā hua manu, ka puaʻa, nā sausage, ka moa, a me nā hamburgers. ʻO ke koina haʻahaʻa o ka friction a me ke kūpaʻa wela kiʻekiʻe o kēia mea e hiki ai iā ia ke hana paʻa i nā wahi wela kiʻekiʻe me ka ʻole o ka hoʻohaumia ʻana i ka meaʻai.

3. Nā hose papa meaʻai

Hoʻohana nui ʻia nā hose PTFE no ka lawe ʻana i nā meaʻai a me nā mea inu, me ka waina, ka pia, nā huahana waiū, nā syrup a me nā mea ʻala. ʻO kona inertness kemika e hōʻoiaʻiʻo ʻaʻole ia e hoʻopilikia i ka maikaʻi o nā huahana i lawe ʻia ma ka pae mahana o -60°C a i 260°C, a ʻaʻole hoʻokomo i kekahi kala, ʻono a ʻala paha. Eia kekahi, ua kūlike nā hose PTFE i nā kūlana FDA e hōʻoia i ka palekana o ka meaʻai.

4. Nā sila a me nā gaskets

Hoʻohana ʻia nā sila a me nā gasket PTFE i nā pilina o nā paipu, nā valves a me nā hoe hoʻouluulu o nā lako hana meaʻai. Hiki iā lākou ke pale aku i ka pala mai nā ʻano kemika like ʻole me ka noho paʻa ʻana i nā wahi mahana kiʻekiʻe. Hiki i kēia mau sila ke pale pono i ka meaʻai mai ka haumia ʻana i ka wā o ka hana ʻana me ka hoʻomaʻalahi ʻana i ka hoʻomaʻemaʻe a me ka mālama ʻana i nā lako.

5. Nā mea hoʻopili meaʻai

Hoʻohana ʻia hoʻi ka PTFE i nā mea hoʻopili meaʻai, e like me nā uhi pā ʻaʻole e pipili, nā uhi pepa bakena, a pēlā aku. Hōʻoia kēia mau mea ʻaʻole e pipili ka meaʻai i ka wā o ka hoʻopili ʻana a me ka kuke ʻana, me ka mālama ʻana i ka maʻemaʻe a me ka palekana o ka meaʻai.

6. Nā noi ʻē aʻe

Hiki ke hoʻohana ʻia ka PTFE i nā kia, nā bushings bearing a me nā ʻāpana plastik ʻenekinia i ka hana ʻana i ka meaʻai, hiki ke hoʻomaikaʻi i ke kūpaʻa ʻana o ka ʻaʻahu a me ke kūpaʻa ʻana i ka corrosion o nā lako hana aʻo ka hoʻemi ʻana i nā kumukūʻai mālama.

Nā noʻonoʻo palekana

ʻOiai he nui nā waiwai maikaʻi o ka PTFE, pono nō ʻoe e makaʻala i kona palekana i ka wā e hoʻohana ai i ka ʻoihana meaʻai. Hiki i ka PTFE ke hoʻokuʻu i nā kinoea ʻino i nā mahana kiʻekiʻe, no laila pono e kāohi i ka mahana hoʻohana a pale i ka hoʻomehana wela kiʻekiʻe no ka manawa lōʻihi. Eia kekahi, he mea nui e koho i nā mea PTFE e hoʻokō i nā koi kānāwai pili.
