Nā laʻana o nā mea a me kā lākou waiwai

ʻO ka nā mea pono he mau meakūlohelohe a i ʻole hana ʻino) hoʻohana ʻia e kūkulu i nā mea ʻē aʻe. Kēlā me kēia ʻoihana hoʻohana i nā pono kikoʻī. ʻO kahi laʻana, no ka ʻoihana kūkulu ua hoʻohana ʻia lākou ma ke ʻano he mea metala, nā sima a me nā keramika, i waena o nā mea 'ē aʻe, ʻoiai ka pulupulu, ka hulu hipa a me nā huahana synthetic i hoʻohana ʻia i ka ʻoihana lole.

Hoʻokaʻawale ʻia kēlā me kēia meahana mai nā mea ʻē aʻe e kāna mau waiwai. Aia i ka pōʻaiapili āu e hoʻopaʻa ai i kahi mea a i ʻole nā mea ʻē aʻe āu e makemake ai e hoʻohālikelike iā ia, ʻokoʻa nā waiwai e pili pono ana.

ʻO kahi laʻana, inā makemake mākou e ʻike i ke kumu e hana ai ka aila i kahi papa ma luna o ka wai, e hoihoi mākou i nā waiwai ʻelua: solubility a nuʻa. ʻO nā waiwai ʻē aʻe e like me ka paʻakikī, kala, ʻala a i ʻole ka lawe ʻana o ka uila i mea nui.

Nānā: Pahee, laumania, ʻeleʻele, paʻa a me nā pono wai

Waiwai

Hiki i nā waiwai ke:

Ka mānoanoa: Ka nui o ka palaoa i kahi nui i hāʻawi ʻia
Kūlana kino: Hiki iā kūpaʻa, wai a i ʻole kinoea.
Nā waiwai Organoleptic: Kala, ʻala, ʻono
Kuhi paila: Ke kiʻekiʻena mahana i hiki i kahi mea i hiki i kahi moku wai. Ma luna o kēlā mahana e lilo i mokuʻāina.
Kuhi hoʻoheheʻe: Ke kiʻekiʻena mahana i kahi mea i kahi kūlana paʻa. Ma luna o kēlā mahana e lilo i mokuʻāina wai.
Solubility: Ka hiki o kekahi mea e hoʻoheheʻe i kekahi mea ʻē aʻe
ʻOʻoleʻa: Ke kūpaʻa o kahi mea i nā perforations.
Uila uila: Ka hiki o kahi mea e alakaʻi ai i ka uila.
Hoʻololi: Ka hiki o kahi mea e piʻo me ka haki ʻole. ʻOʻoleʻa kona ʻaoʻao.
Opacity: Ka hiki ke pale i ka hele o ke kukui. ʻO translucency kona ʻaoʻao.

Nā laʻana o nā mea a me kā lākou waiwai

Laau ʻoka: ʻO ka lāʻau paʻakikī a kaumaha hoʻi, no ka mea, aia kona ākea ma waena o 0.760 a me 0.991 kg / m3. Ma muli o kona ʻano kemika, kūpaʻa loa ia i ka pala. Ma muli o nā kūlana organoleptic (ʻala), hoʻohana ʻia ia no nā pahu waina, e hoʻoili ana i kona ʻano i ka huahana hope loa.
Aniani: He mea paʻakikī ia (he paʻakikī loa e hou a wili paha), me kahi mahana hoʻoheheʻe kiʻekiʻe (1723 kekelē) no laila ʻaʻole ia e hoʻopili ʻia e nā loli o ka mahana. ʻO ia ke kumu e hiki ai ke hoʻohana i nā ʻoihana like ʻole, mai ke kūkulu ʻana (puka aniani) a i nā papa ʻaina. Hiki ke hoʻohui i nā pigments i ke aniani e hoʻololi i kona kala (nā waiwai organoleptic) a me nā papa e opaque, e pale ana i ka hele o ke kukui. He insulate ia mai ka walaʻau, ka mahana, a ʻaʻohe ona uila uila.
O Minvielle: Nā mea hana i hana ʻia mai nā filament silikone dioxide. Maikaʻi nō insulator pumehana, akā ʻaʻole kūʻē i nā kemika. ʻO ia kahi mea acoustic a me insulator uila maikaʻi. Ma muli o kona maʻalahi hiki ke hoʻohana ʻia ia i nā hale lole, nā lole pale kiʻekiʻe, nā pou vault pou.
ʻO Aluminium: I nā papa lahilahi, ʻaʻole ia he metala maʻalahi wale nō akā palupalu hoʻi, ʻo ia hoʻi, he palupalu loa ia. I nā papa mānoanoa lilo i mea ʻoʻoleʻa. ʻO kēia ke kumu e hiki ai ke hoʻohana i ka alumini i ka hoʻopili maʻalahi (ʻoiai i kapa ʻia ʻo "alumini pepa") akā i nā ʻano ʻoʻoleʻa nui o nā nui āpau, mai nā kini ʻai i nā mokulele.
Kukena: Ka huikau o ka pōhaku kalina a me ka pālolo honua. Hoʻoikaika ia i ka pili ʻana me ka wai. Kūpaʻa ia i nā kemika a me nā mahana wela. Eia nō naʻe, ke emi nei kona kūpaʻa i ka holo ʻana o ka manawa no ka mea ua hoʻonui ʻia kona porosity.
Gula: He metala palupalu a kaumaha hoʻi ia. Ma muli o ke kūpaʻa kiʻekiʻe i ka popopo, hoʻohana ʻia ia i ka ʻoihana a me ka uila. ʻIke ʻia ia no nā ʻano organoleptic (kona ʻōlinolino a me ke kala) no laila e huikau ʻia me nā metala ʻē aʻe o ka waiwai ʻoihana haʻahaʻa. He kiʻekiʻena 19,300 kg / m3. ʻO kāna kiko hoʻoheheʻe he 1,064 kekelē.
Pulupulu pulupulu: ʻO ia kekahi o nā mea i hoʻohana ʻia i ka ʻoihana lole. ʻO kona ʻano mai keʻokeʻo a keʻokeʻo keʻokeʻo. Liʻiliʻi loa ke anawaena o ka puluniu, ma waena o 15 a me 25 mau micrometers, kahi e palupalu ai i ka hoʻopā ʻana, no laila e mahalo nui ʻia ia ʻoihana.
Lycra a i ʻole elastane: He lole polyurethane ia. Ua maikaʻi ʻulupā, hiki ke hoʻolōʻihi ʻia a 5 mau manawa kona nui me ka haki ʻole. Hoʻohui, hoʻi koke i kona ʻano kumu. ʻAʻole ia e mālama i ka wai ma waena o nā olonā o kona lole, no laila e maloʻo koke.
PET (polyethylene terephthalate): He thermoplastic ia o ka rigidity kiʻekiʻe, paʻakikī a me ke kūpaʻa. Kūpaʻa loa ia i nā mea ʻenekini a me nā lewa (wela, ʻūmū) no laila hoʻohana ʻia ia i ka mea inu, wai a me nā ipu lāʻau.
Porcelain: He mea pālolo kahi i wehewehe ʻia e ke kaulike a me ka translucent, a ʻokoʻa ia mai nā keramika ʻē aʻe. He ʻoʻoleʻa akā palupalu a me ka liʻiliʻi o ka uila. Eia naʻe, kūpaʻa loa ia i nā kemika a me nā mahana wela.
