ʻO ka paipu PTFE pale wela kiʻekiʻe no ka mīkini paʻi 3D

He aha ka PTFE?

ʻO ka PTFE i ʻike nui ʻia ʻo "plastic mōʻī", he polymer polymer i hana ʻia me ka tetrafluoroethylene ma ke ʻano he monomer. Ua ʻike ʻia e Kauka Roy Plunkett i ka makahiki 1938. Malia paha ke manaʻo nei ʻoe he mea ʻē kēia mea, akā ke hoʻomanaʻo nei ʻoe i ka pā non-stick a mākou i hoʻohana ai? Ua uhi ʻia ka pā non-stick me kahi uhi PTFE ma luna o ka pā, i ʻole e pipili ka meaʻai i lalo o ka pā, e hōʻike ana i ke kūpaʻa wela kiʻekiʻe o ka PTFE a me nā ʻano lubrication kiʻekiʻe. I kēia mau lā, hana ʻia nā mea maka pauka PTFE i nā huahana o nā ʻano like ʻole, e like me nā paipu PTFE, ka ʻili lahilahi PTFE, nā kaola PTFE, a me nā papa PTFE, i hoʻohana ʻia ma nā ʻano like ʻole. A laila, kūkākūkā mākou i ka hoʻohana ʻana o nā paipu PTFE i nā mea paʻi 3D.

He mea ʻawahia ka PTFE?

He hoʻopaʻapaʻa ke kumuhana inā he ʻawahia ka PTFE a ʻo ka mea maoli ʻaʻole ia he ʻawahia.

Akā i ka wā i hoʻohui mua ʻia ai ka PFOA (Perfluorooctanoic Acid) i nā mea hana PTFE, ua hoʻokuʻu ʻia ka toxin i ka wā e hoʻohana ʻia ai i nā mahana kiʻekiʻe. He paʻakikī ke hoʻohaumia ʻia ka PFOA mai ke kaiapuni, a hiki ke komo i loko o nā kānaka a me nā meaola ʻē aʻe ma o nā mea kino, ka ea a me ka wai, a i ka hala ʻana o ka manawa hiki ke alakaʻi i nā helu hānau haʻahaʻa a me nā maʻi ʻē aʻe o ka ʻōnaehana pale. Akā i kēia manawa ua pāpā ʻia ka PFOA e nā luna e hoʻohui iā ia i nā mea hana PTFE. Hōʻike pū kā mākou mau hōʻike hoʻāʻo mea maka a pau ʻaʻohe ʻāpana PFOA.

No ke aha e hoʻohana ai nā mea paʻi 3D i nā ʻōmole PTFE?

Me ka wikiwiki o ka hoʻomohala ʻana o The Times, ʻo ka mīkini paʻi 3D kahi ʻenehana hana wikiwiki, i ʻike ʻia hoʻi ʻo ka hana hoʻohui. He hana ia o ka hoʻopili ʻana a i ʻole ka hoʻōla ʻana i nā mea ma lalo o ka mana kamepiula e hana i nā mea ʻekolu-dimensional, ma ke ʻano maʻamau me ka hoʻohana ʻana i nā mole wai a i ʻole nā ​​​​ʻāpana pauka e hoʻohui pū a kūkulu hope i nā mea papa ma ka papa. I kēia manawa, ua hoʻokomo nui ʻia ka ʻenehana hoʻoheheʻe paʻi 3D: ke ʻano hoʻoheheʻe ʻana i ka waiho ʻana, e like me ka hoʻohana ʻana i ka thermoplastic, nā mea metala ʻōnaehana kristal maʻamau, lohi kona wikiwiki hoʻoheheʻe ʻana, a ʻoi aku ka maikaʻi o ka wai hoʻoheheʻe mea;

Eia nō naʻe, he hoʻoilina mōʻaukala ko nā mīkini paʻi 3D o ke poʻo ʻeha, maʻalahi ke hoʻopili! ʻOiai he haʻahaʻa ka helu hāʻule ʻana o ka mīkini paʻi 3D, i ka wā e hana ʻia ai, ʻaʻole ia e hoʻopilikia wale i ka maikaʻi o ka paʻi ʻana, akā e hoʻonele pū i ka manawa a me nā mea paʻi, a hōʻino paha i ka mīkini. Manaʻo ka poʻe he nui ua wela loa ka ʻōpū puʻu no ka mea ua hana ʻia me kahi mea hoʻohui. No ka mea, koi nā mea ʻenekinia i kahi mahana mau kiʻekiʻe, kiʻekiʻe loa nā koi no nā ʻāpana. No laila, hoʻohana ka mīkini paʻi 3D i ka ʻōmole PTFE ma ke ʻano he ʻōmole hānai. Pono e lawe ʻia nā mea maka he nui i ke poʻo o ka mīkini paʻi i ke kūlana heheʻe, a pono e hoʻokō ka ʻōmole lawe i nā koi o ka wahi o ka mīkini paʻi, no laila i kēia manawa ua hoʻololi ka nui o nā mea hana i ka ʻōmole deragona fluorine hao i kūkulu ʻia, haʻahaʻa ka conductivity thermal o ka deragona fluorine hao a me ke kila kila kila, hiki ke hoʻemi pono i ka mahana o ka ʻōmole deragona fluorine hao, me ka ʻōmole deragona fluorine hao, ua emi nui ka helu hāʻule ʻana o ka hoʻopili ʻana. No laila ʻo ia ke koho maikaʻi loa no nā mīkini paʻi 3D.
