ʻO kā mākou plastic plastics crystalline a i ʻole amorphous?ʻO ka mea mua, pono mākou e hoʻomaopopo i ka ʻokoʻa koʻikoʻi ma waena o ka crystalline a me ka amorphous.
ʻO nā kristal he mau ʻātoma, nā ʻona a i ʻole nā molekole i hoʻonohonoho ʻia ma ka lewa e like me kekahi manawa e hana i kahi paʻa me kekahi ʻano geometric maʻamau i ka wā o ka crystallization kaʻina.ʻO ka Amorphous kahi kino amorphous, a i ʻole amorphous, amorphous solid, ʻo ia ka paʻa i hoʻonohonoho ʻole ʻia nā ʻātoma ma kahi ʻano kikoʻī, pili i kahi aniani.
ʻO nā kristal maʻamau he daimana, quartz, mica, alum, paʻakai papa, keleawe sulfate, kō, monosodium glutamate a pēlā aku.ʻO nā amorphous maʻamau he paraffin, rosin, asphalt, rubber, aniani a pēlā aku.
He ākea loa ka māhele ʻana o nā kristal, a ʻo ka hapa nui o nā mea paʻa i ke ʻano he kristal.Hiki ke hoʻololi ʻia nā kinoea, nā wai a me nā mea amorphous i mau kristal ma lalo o kekahi mau kūlana kūpono.ʻO ke ʻano ʻekolu-dimensional periodic structure o ka hoʻonohonoho ʻana o nā ʻātoma a i ʻole nā molekole i loko o ke aniani ka mea maʻamau a koʻikoʻi o ke aniani.
Aia nā kino amorphous maʻamau i ke aniani a me nā pūhui polymer he nui e like me styrene a pēlā aku.I ka lōʻihi o ka wikiwiki o ka hoʻomaha ʻana, e hana kekahi wai i kino amorphous.Ma waena o lākou, e maloʻo loa ia, a ʻo ka lattice a i ʻole skeleton i ka thermodynamically favorable crystalline state e nalowale i ka wikiwiki o ka neʻe ʻana ma mua o ka hoʻonohonoho ʻia ʻana o nā ʻātoma, akā paʻa mau ka puʻunaue pili o nā ʻātoma i ka moku wai.
No laila, hiki iā mākou ke hoʻoholo he amorphous nā plastics maʻamau i ke ola.
