He aha ka PTFE?
ʻO ka PTFE i kapa ʻia ʻo ka "plastic King", he polymer polymer i hana ʻia me ka tetrafluoroethylene ma ke ʻano he monomer.Ua ʻike ʻia e Dr. Roy Plunkett i ka makahiki 1938. He mea ʻē paha ʻoe i kēia mea, akā hoʻomanaʻo anei ʻoe i ka pā non-stick a mākou i hoʻohana ai?Hoʻopili ʻia ka pā non-stick i kahi uhi PTFE ma luna o ka ʻili o ka pā, i ʻole e pili ka meaʻai i lalo o ka pā, e hōʻike ana i ka PTFE kiʻekiʻe wela a me nā ʻano lubrication kiʻekiʻe.I kēia mau lā, hana ʻia ka PTFE pauka maka i nā huahana o nā ʻano like ʻole, e like me nā paipu PTFE, nā kiʻi ʻoniʻoni ʻoniʻoni PTFE, nā pahu PTFE, a me nā pā PTFE, i hoʻohana ʻia ma nā ʻano ʻokoʻa.A laila, kūkākūkā mākou i ka hoʻohana ʻana o nā paipu PTFE i nā mea paʻi 3D.
He ʻawaʻawa anei ka PTFE?
He mea hoʻopaʻapaʻa ke kumuhana o ka PTFE a ʻaʻohe mea ʻawaʻawa.
Akā, i ka manawa i hoʻohui muaʻia ai ka PFOA (Perfluorooctanoic Acid) i nā meaʻai PTFE, ua hoʻokuʻuʻia ka meaʻawaʻawa i ka wā i hoʻohanaʻia i nā mahana wela.He paʻakikī ka hoʻohaʻahaʻa ʻana i ka PFOA mai ke kaiapuni, a hiki ke komo i ke kanaka a me nā mea ola ʻē aʻe ma o nā mea kino, ka ea a me ka wai, a i ka wā lōʻihi hiki ke alakaʻi i ka emi ʻana o ka momona a me nā maʻi ʻē aʻe.Akā i kēia manawa ua pāpā ʻia ʻo PFOA e nā mana e hoʻohui iā ia i nā mea ʻai PTFE.ʻAʻole hōʻike ʻia kā mākou hōʻike hōʻike hoʻāʻo maka ʻaʻohe mea PFOA.
No ke aha e hoʻohana ai nā mea paʻi 3D i nā paipu PTFE?
Me ka hoʻomohala wikiwiki ʻana o The Times, ʻo ka mīkini paʻi 3D kahi ʻenehana hana wikiwiki, ʻike ʻia hoʻi ʻo ka hana hoʻohui.He kaʻina hana ia o ka hoʻohui ʻana a i ʻole ka hoʻōla ʻana i nā mea ma lalo o ka mana kamepiula e hana i nā mea ʻekolu-dimensional, me ka hoʻohana maʻamau i nā molekole wai a i ʻole nā palapala pauka e hui pū ai a kūkulu hope i nā mea i papa ma ka papa.I kēia manawa, hoʻokomo ʻia ka ʻenehana hoʻoheheʻe 3D: ka hoʻoheheʻe ʻana i ke ʻano, e like me ka hoʻohana ʻana i ka thermoplastic, nā mea metala ʻōnaehana kristal maʻamau, lohi ka wikiwiki o ka hoʻoheheʻe ʻana, a ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻana o nā mea;
Eia nō naʻe, loaʻa i nā mea paʻi 3D kahi hoʻoilina mōʻaukala o ke poʻo, maʻalahi ke hoʻopili!ʻOiai he haʻahaʻa ka hapa o ka paʻi paʻi 3D, i ka manawa e puka mai ai, ʻaʻole ia e hoʻopilikia wale i ka maikaʻi o ka paʻi ʻana, akā e hoʻopau i ka manawa a me nā mea paʻi, a me ka hōʻino ʻana i ka mīkini.Manaʻo ka nui o ka poʻe he wela loa ka puʻu puʻu no ka mea i hana ʻia me kahi mea hoʻohui.No ka mea e koi ana nā mea papa hana ʻenekinia i kahi mahana hoʻomau kiʻekiʻe, kiʻekiʻe loa nā koi no nā ʻāpana.No laila, hoʻohana ka mea paʻi kiʻi 3D i ka paipu PTFE ma ke ʻano he mea hānai.Nui nā mea maka e pono e lawe ʻia i ke poʻo paʻi i ka mokuʻāina o ka heheʻe, a pono e hoʻokō ka paipu lawe i nā koi ākea o ka mea paʻi, no laila i kēia manawa ua hoʻololi nā mea hana i ka hao fluorine dragon tube, ka hao fluorine dragon a me ke kila kila. He haʻahaʻa ka thermal conductivity, hiki ke hoʻohaʻahaʻa pono i ka mahana o ka puʻu puʻu, me ka hao fluorine dragon tube, hoʻemi nui ʻia ka nui o ka hoʻopili ʻana.No laila ʻo kēia ke koho maikaʻi loa no nā mea paʻi 3D.
Inā ʻoe i ka ʻoihana paʻi 3D, makemake paha ʻoe
ʻO kēia ka hōʻike maʻamau o nā hiʻohiʻona nui o nā paipu PTFE:
1. ʻAʻole paʻa: He inert, a aneane pau ʻole nā mea i hoʻopaʻa ʻia me ia.
2. Heat resistance: ferroflurone loaʻa i ka wela wela.Hiki ke hoʻohana mau ʻia ka hana maʻamau ma waena o 240 ℃ a me 260 ℃.ʻO ka pale wela manawa pōkole i 300 ℃ me kahi helu heheʻe o 327 ℃.
3. Lubrication: PTFE he haʻahaʻa friction coefficient.Hoʻololi ke koena friction i ka wā e paheʻe ai ka ukana, akā aia ka waiwai ma waena o 0.04 a me 0.15 wale nō.
4. Ke kū'ē i ka wā:ʻaʻoheʻelemakule, aʻoi aku ka maikaʻi o ke olaʻole i ka plastic.
5. Non-toxic: ma ke kaiapuni maʻamau i loko o 300 ℃, loaʻa iā ia ka inertia physiological a hiki ke hoʻohana ʻia no ka lāʻau lapaʻau a me ka meaʻai.
ʻO ke kūʻai ʻana i ka paipu PTFE kūpono ʻaʻole wale e pili ana i ke koho ʻana i nā kikoʻī like ʻole no nā noi like ʻole.ʻOi aku e koho i kahi mea hana hilinaʻi.ʻO Besteflon Fluorine plastic Industry Co., Ltd. kūikawā i ka hana ʻana i nā paipu PTFE kiʻekiʻe a me nā paipu no 15 mau makahiki.Inā he nīnau a he pono, e ʻoluʻolu e nīnau mai iā mākou no ka ʻōlelo aʻo ʻoihana.
