ʻO ka palupalu ka hiki o kahi mea e hoʻololi i kona kinona ma ke kūlou ʻana me ka haki ʻole. ʻO ka maʻalahi ka hiki ke maʻalahi, hoʻopili i nā loli i ke ʻano a me ka neʻe. He loli mechanical ia.
Eia nō naʻe, he mea nui ʻaʻole e huikau ka palupalu - kūʻē kūʻē (ke kūlike ʻole) me ka palupalu - kūʻē paʻakikī (paʻakikī). Hiki ke hoʻopili ʻia a hoʻololi ʻia kahi mea palupalu i nā ala he nui a ʻaʻole wale ma ke kūlou ʻana (ua pau kāna malleability). ʻAʻole hiki ke hoʻoheheʻe ʻia kahi mea maʻalahi a ʻae wale i nā hoʻololi i ke kūlou ʻana.
ʻAʻole paʻakikī paha kahi mea ʻoʻoleʻa. ʻO kahi laʻana, he lāʻau paʻa ka wahie akā he paʻakikī paʻakikī, no ka mea, koi ʻia ka ikaika liʻiliʻi e hou iā ia, ke hoʻohālikelike ʻia me ka mea kila.
Pili mau nā laʻana i hāʻawi ʻia i nā mea maʻalahi a paʻakikī. ʻO kahi laʻana, aia ka pepa pahu i waena o nā mea ʻoʻoleʻa i kūʻē i ka pepa, kahi mea i hana ʻia mai nā olonā like, akā ʻoi aku ka maʻalahi. Akā loaʻa ka loli iki o ka pepa pahu i ka hoʻohālikelike ʻia, no ka laʻana, hao.
Ma ka ʻaoʻao ʻē aʻe, aia kekahi mau mea i hiki ke maʻalahi a paʻakikī paha e like me ko lākou mānoanoa. ʻO kahi laʻana, hiki i ka polyethylene kiʻekiʻe (HDPE) ke maʻalahi i nā pale lahilahi, akā ʻoi aku ka paʻakikī i nā papa mānoanoa, a ʻo ia ka mea e hana ʻia ai nā mea e like me nā ipu ʻōpala a i ʻole nā paipu nui. ʻO ka hapa nui o nā mea i hōʻike ʻia ma lalo nei hiki ke loli a paʻa hoʻi.
- E nānā pū: nā mea elastic
Nā laʻana o nā mea maʻalahi
- Pepa. He pepa lahilahi ia o ka pasta i hana ʻia mai nā fibre mea kanu lepo. ʻOi aku ka maʻalahi o ka pepa inā he refinement wīwī ʻo ia, ʻo ia hoʻi, ʻoi aku ka liʻiliʻi o ka hydrated o kāna mau olonā. ʻOi aku ka paʻakikī nā pepa me nā olonā hydrated.
- LDPE / LDPE (Low Density Polyethylene). ʻO ia kahi ʻano thermoplastic recyclable i hoʻohana ʻia i ka hoʻopili maʻalahi, e like me nā ʻeke, kiʻi ʻoniʻoni pilikino a me nā mīkina lima. ʻOiai hoʻohana ʻia ia i nā ʻāpana paʻa o nā ipu (e like me nā pāpale ʻōmole), hoʻohana nui ʻia ia i nā pale lahilahi e maʻalahi ai. Hoʻohana ʻia ia no ke kūpaʻa kemika maikaʻi. Hiki iā ia ke hoʻomanawanui i nā mahana a 80ºC, a i ʻole 95ºC no nā wā pōkole. Ma muli o kona loli, kiʻekiʻe kona kūpaʻa i nā hopena mechanical.
- ʻO Aluminium. He metala ʻaʻole wale ia e maʻalahi akā palupalu hoʻi, ʻo ia, maʻalahi loa ia. Eia nō naʻe, he mea nui e hoʻomaopopo i nā papa mānoanoa e ʻoʻoleʻa ana ia. No kēia kumu, hiki ke hoʻohana ʻia ke alumini i ka wahī palupalu (ʻoiai i kapa ʻia ʻo "alumini pepa") akā i nā ʻano ʻoʻoleʻa nui o nā nui āpau, mai nā kini ʻai i nā mokulele.
- Mea pīlali. ʻO kahi polymer inorganic. Ma muli o kona kūpaʻa ma nā mahana wela, hoʻohana nui ʻia ia e hana i nā moʻo a me nā mea hoʻopili i ka ʻoihana. Hoʻohana pū ʻia ia sterilized i nā implants, e like me ka umauma implants, valves prostheses and heart.
- Hiki iā ia ke lawelawe iā ʻoe: Ductile material
Nā laʻana o nā mea paʻa
- Pepa pepa. Hana ʻia ia i mau papa o nā mea maʻalahi: pepa. Eia nō naʻe, paʻakikī ka pepa pahu ma muli o kona mānoanoa a ma muli o ke kaʻina e hele ai nā olonā: gluing. Hiki ke hana ʻia mai nā mea i hana hou ʻia, a lilo ia i mea waiwai. Ma muli o ka paʻakikī a me ke kumu kūʻai haʻahaʻa, ʻo ia ka mea i koho maʻamau ʻia e hana i nā pahu e ʻae i ka lawe ʻana i nā mea nāwaliwali ʻē aʻe.
- PET (polyethylene terephthalate). He palakiko me ka ʻoʻoleʻa kiʻekiʻe, akā ʻo ka paʻakikī a me ke kūpaʻa. Hoʻohana ʻia ia i ka mea inu, wai a me nā ʻōpala lāʻau lapaʻau ma muli o ke kūpaʻa ʻana i nā ʻenekini a me nā ʻea lewa (wela, ʻūmū).
- Polypropylene (PP). ʻO ia kekahi o nā pono i hiki ke manaʻo ʻia he ʻoʻoleʻa a maʻalahi paha e pili ana i kona mānoanoa. Eia nō naʻe, hoʻohana ʻia ia ma nā mea ʻoʻoleʻa. He waena mawaena o ka polyethylene kiʻekiʻena kiʻekiʻe a me ka polyethylene haʻahaʻa haʻahaʻa. Kūpaʻa loa ia i nā mahana kiʻekiʻe a i ka hapa nui o nā waikawa a me nā alkalis. Hoʻohana ʻia lākou i ka hana ʻana i nā hihia CD, nā lako hale, nā pā ipu a me nā papa ʻoki. He lako ia e hoʻohana ākea ʻia i ka gastronomy a me nā lāʻau (mai nā lako hale hana i nā prosthetics) ʻoiai ʻaʻole ia e waiho i kekahi ʻano koena a i ʻole nā mea ʻino ʻino. ʻO ia nā mea i wae ʻia no nā waihona kemika ma muli o ke kūʻē ʻana iā lākou. I kona ʻano maʻalahi hiki ke hoʻohana ʻia i nā bandages, nā kaula a me nā pae, akā i nā kiʻi lahilahi i hoʻohana ʻia i ka wahī meaʻai.
- Aniani. He mea inorganic ia i kū i ke kūlohelohe. ʻOʻoleʻa a paʻakikī paʻakikī, ʻo ia hoʻi, hāʻawi ia i ka nui o ke kūpaʻa i ka abrasion, ʻoki, scratches a me nā komo. ʻOiai kēia, hiki ke hana ʻia nā mea aniani o nā ʻano like ʻole no ka mea hiki ke hoʻoheheʻe ʻia i nā mahana i ʻoi aku ma mua o 1,200 ºC. Ke hāʻule hou ka mahana, paʻa hou ia i ke ʻano hou i loaʻa.
- Mea hao. He metala ʻoʻoleʻa ia, ʻo ka paʻakikī a me ka lahilahi. ʻO ia ka mea hao paʻa loa i hoʻohana nui ʻia e ke kanaka, a ʻoi aku ka nui o nā mea i hana ʻia ma ka honua. Hoʻohana ʻia ia e hana i ke kila, kahi hao paʻa ʻē aʻe, ʻo ia ke kinikini (hoʻohui) o ka hao a me ke kalapona.
- Laau. ʻO ia ka ʻike nui o nā kumu lāʻau a ʻoʻoleʻa mau. Kapa ʻia nā "trunks" maʻalahi o nā mea kanu i nā koʻokoʻo a ʻaʻohe ona wahie. Hoʻohana ʻia ka lāʻau e kūkulu i nā mea ʻoʻoleʻa e like me nā kāhiko, nā pākaukau, nā hale, a i ʻole nā moku. ʻAʻole like me nā mea ʻoʻoleʻa e like me ke aniani a me nā metala, hiki ke hoʻoheheʻe e kiʻi i nā ʻano hou, ʻoki ʻia ka lāʻau, kālai ʻia a one ʻia paha, ʻo ia ka mea i kēlā me kēia hihia ʻaʻole ia e kū i kahi mea ʻoʻoleʻa.
Hiki iā ia ke lawelawe iā ʻoe:
- Nā Pono Kūlohelohe a me nā Hana Hana
- Nā mea hoʻohui
- Nā mea hoʻoheheʻe
- Nā Pono Hana Pono
