I ka hana ʻana i kahi huahana, hiki ke paʻakikī ke koho ma waena o ka plastic a me ka metala.Loaʻa i nā mea ʻelua ko lākou mau pono kūʻokoʻa, akā hāʻawi pū lākou i kekahi mau mea like kahaha.No ka laʻana, hiki i ka plastic a me ka metala ke hāʻawi i ka pale wela a me ka ikaika, ʻo ia nā mea nui e noʻonoʻo ai i ka wā o ka hana ʻana.No ke kōkua ʻana iā ʻoe e hoʻoholo i ka ʻike, e wāwahi mākou i nā pōmaikaʻi a me nā hemahema o kēlā me kēia mea ma nā ʻāpana aʻe.Ma ka manawa like, e nānā pū mākou i ka hopena o ke kaiapuni o kēia mau mea ʻelua, aʻu i manaʻo ai he mea nui loa ia iā ʻoe.
ʻO ke ʻano o nā mea ʻelua
Palaki
ʻO ka plastik kahi mea maʻalahi e hāʻawi ana i nā pono he nui, me kona kaumaha māmā, ka lōʻihi, ka hiki ke kūʻai aku, a me ka maʻalahi o ka hoʻololi.Hoʻokumu ʻia ia me nā polymers, he mau molekala paʻakikī i hana ʻia me nā ʻāpana hou a i ʻole nā kaulahao o nā ʻātoma kalapona, e like me ka ethylene, propylene, vinyl chloride, a me styrene.Hoʻohui kēia mau monomers e hana i nā kaulahao lōʻihi e hāʻawi i ka plastic i kona mau waiwai kūʻokoʻa.
Hoʻokumu ʻia nā polymers mai nā monomers, i loaʻa mai ka ʻaila, nā wahie mōʻalihaku, a i ʻole biomass no nā bioplastics.Ho'ākāka nā Monomers i nā ʻano mua, ke ʻano, a me ka nui o nā polymers.Eia nō naʻe, hoʻokomo pū ka hana hana i nā mea hoʻohui e hoʻonui, hoʻomaikaʻi, a hoʻololi i nā waiwai o nā plastics.Hiki i kēia mau mea hoʻohui ke hoʻomaikaʻi i ka maʻalahi, ka lōʻihi, ka pale ʻana o UV, ke kūpaʻa ahi, a i ʻole ke kala, no ka laʻana.
Metala
ʻO nā metala nā mea kemika i loaʻa i ke ʻano i loaʻa nā waiwai waiwai e like me ka uila kiʻekiʻe a me ka thermal conductivity, malleability, a me ka ductility.Ua hoʻohana nā kānaka i kēia mau ʻano no ka manawa lōʻihi.Eia nō naʻe, me ka hoʻomohala ʻepekema, hoʻomaka nā kānaka e hoʻohui i ʻelua metala e loaʻa ai nā waiwai i makemake ʻia, a ua hānau ʻia nā alloys.
Hana ʻia nā Alloys e ka hui ʻana i nā metala a me nā metala ʻole, a i ʻole ʻelua a ʻoi aku paha mau mea, e hana i kahi mea hou me nā ʻano maikaʻi.
ʻO nā metala nā mea kemika kūlohelohe i hōʻike ʻia e ko lākou kiʻekiʻe uila a me ka thermal conductivity, malleability, a me ka ductility.Ua hoʻohana ʻia lākou e nā kānaka no nā kaukani mau makahiki ma muli o kā lākou mau waiwai kūʻokoʻa.Akā, ʻo nā alloys, he mau mea metala i hana ʻia e ka hui ʻana i ʻelua a ʻoi aku paha nā mea, me nā metala a me nā metala ʻole, e hana i kahi mea hou me nā waiwai i hoʻonui ʻia.
Na waiwai a me na ano
Metal-ʻO ke koho kūpono no kekahi mau hoʻohana.
• ʻO ka hoʻomanawanui wela: Mahalo i kona wahi hoʻoheheʻe kiʻekiʻe, kūpono ia no nā hoʻonohonoho wela loa.
• Paʻa: ʻO ka paʻa o ke metala he koho maikaʻi loa ia no nā ʻāpana e amo ana i ke kaumaha a me nā hale kākoʻo.
• Nui nā koho: hiki iā ʻoe ke koho mai nā ʻano mea like ʻole, me ka keleawe conductive a me kāna mau mea e like me ke keleawe a me ke keleawe, a me ke kila, alumini, a me nā mea ʻē aʻe.
• Hoʻopau i ka hana maʻamau: He nui nā koho hoʻopau ʻana i ka metala (anodizing, pauka, etc.).
ʻOiai he mau mea maikaʻi ka metala, hiki i ka plastic ke hāʻawi i nā pōmaikaʻi like ke hoʻolālā ʻia a ʻenekinia pololei ʻia.No ka laʻana, hiki i ka plastic ke hāʻawi i ka pae like o ka lōʻihi, ka ikaika, a me ke kūpaʻa ʻana i ka corrosion e like me ke metala, e lilo ia i mea kūpono no nā noi like ʻole.Hoʻohui ʻia, hiki ke hoʻoheheʻe ʻia ka plastic i nā ʻano paʻakikī a me nā ʻano i hiki ʻole ke metala, e hāʻawi ana i ka maʻalahi o ka hoʻolālā a me ka hoʻopiʻi nani.Ma ke koho pono ʻana i ke ʻano pono o ka plastic a me ka ʻenekinia pono, hiki ke loaʻa nā pōmaikaʻi like me ka metala, a ʻoi aku paha i kekahi manawa ma mua o lākou.
Nā Kaʻina Hana Hana
Loaʻa i nā metala a me ka plastic kā lākou hana ponoʻī.Plastic, maʻamauhoʻoheheʻe ʻia, hiki no hoi ke thermoformed, extruded a machined.ʻO nā metala, i hana pinepine ʻia, hiki ke hanamake-casting, i hoailonaiaaextruded.Hana ʻia ka hana nui o nā ʻāpana metala me ka hoʻolei ʻana a i ʻole forging.Hana Metala Kuʻunaʻaoʻao.
Nā noi a me nā ʻoihana
ʻO ka hapa nui o nā ʻoihana e hilinaʻi i nā mea metala a me ka plastic e hana pono ai.Hoʻohana pinepine nā ʻāpana metala i nā ʻāpana metala, aerospace, aerospace, kūkulu, a me nā ʻāpana plastic i nā lāʻau lapaʻau, nā meaʻai a me nā mea inu, nā kaʻa kaʻa, ka pahu a me nā mea haʻuki.ʻO ka ʻoihana lāʻau lapaʻau, ʻo ia hoʻi, hoʻohana i nā ʻāpana metala a me ka plastic i kā lākou huahana.
Ka hopena o ke kaiapuni o ka metala a me ka plastik
ʻO ka aluminika a me ke kila he mea hiki ke hoʻohana hou ʻia, e koi ana i ka liʻiliʻi o ka ikehu e hana ai i ka hoʻohālikelike ʻana i ka unuhi ʻana i nā mea maka mai ka honua.Eia nō naʻe, ʻoi aku ka paʻakikī o ka hana ʻana i ka plastic, me nā ʻano like ʻole o ka kūleʻa e pili ana i ke ʻano o ka plastic a me ka hiki ke loaʻa i nā papahana hana hou kūloko.ʻOiai ʻo ka hana ʻana i nā plastics mai nā wahie mōʻalihaku he kumu waiwai, ʻo ka hoʻomohala ʻana i nā plastics bio-based a me nā ʻenehana hana hou e hana ana e hōʻemi i nā hopena kaiapuni.Hiki i nā ʻoihana ke pōmaikaʻi mai ka hoʻohana ʻana i ka plastic recycled, e like me ka plastic ocean, no ka mea e hiki ai iā lākou ke mālama i nā pono o nā huahana plastic me ka hāʻawi ʻana i kā lākou mea kūʻai aku i nā koho eco-friendly.
E ʻimi i nā hoʻonā me RuiCheng
ʻO ke koho ma waena o ka plastic a me ka metala e pili ana i kāu hihia hoʻohana ponoʻī, nā kūlana ʻoihana, a me nā pahuhopu kaiapuni.ʻOiai kūpono paha ka metala no kekahi mau hoʻohana, he mea koʻikoʻi ia e loiloi i ka hiki ke hoʻololi ʻia o ka plastic, ka maikaʻi o ke kumu kūʻai, a me ka hiki ke hoʻohana ʻia i ka ʻenehana i ka wā e hoʻoholo ai i kahi mea no ke kaʻina hana o kāu huahana.
Makemake ʻoe e ʻike hou aʻe e pili ana i ke kaʻina plastik a i ʻole ka hana metala e ʻoluʻolu e nānā i kā mākouhoʻoheheʻe ʻia ʻana i ka plastikkaʻina hana aKūkākūkā wikiwiki
ʻAʻole maopopo i ka mea maikaʻi loa no kāu pono?E hoʻokaʻaʻike mai iā mākoui kēia manawa, a e hauʻoli kā mākou hui ʻoihana iā ʻoe i ka ʻimi ʻana i kāu mau koho a hāʻawi iā ʻoe i kahi ʻōlelo.
