He aha nā ʻano o ka Polypropylene (PP)?
ʻO kekahi o nā waiwai koʻikoʻi o ka polypropylene: 1. Ke Kūʻē Kemika: ʻAʻole pane maʻalahi nā kumu a me nā waikawa i hoʻoheheʻe ʻia me ka polypropylene, kahi e lilo ai ia i koho maikaʻi no nā ipu o ia mau wai, e like me nā mea hoʻomaʻemaʻe, nā huahana kōkua mua, a me nā mea hou aku. 2. Elasticity a me Toughness: E hana ʻo Polypropylene me ka elasticity ma luna o kahi ʻano o ka deflection (e like me nā mea āpau), akā e ʻike pū ia i ka deformation plastic i ka wā mua o ke kaʻina hana deformation, no laila ua manaʻo ʻia he mea "paʻakikī". ʻO ka paʻakikī kahi huaʻōlelo ʻenekinia i wehewehe ʻia ʻo ia ka hiki o kahi mea ke deform (plastically, ʻaʻole elastically) me ka haki ʻole.. 3. Ke Kūʻē Luhi: Mālama ʻo Polypropylene i kona ʻano ma hope o ka nui o ka torsion, bending, a/a i ʻole flexing. ʻO kēia waiwai e... -

He aha ka Polypropylene (PP)?
He thermoplastic paʻakikī, paʻa, a crystalline ka Polypropylene (PP). Hana ʻia ia mai ka monomer propene (a i ʻole propylene). ʻO kēia resin hydrocarbon linear ka polymer māmā loa ma waena o nā plastics waiwai āpau. Hiki mai ka PP ma ke ʻano he homopolymer a i ʻole he copolymer a hiki ke hoʻonui nui ʻia me nā mea hoʻohui. Loaʻa iā ia ka hoʻohana ʻana i loko o ka ʻōpala, kaʻa, nā waiwai mea kūʻai aku, nā lāʻau lapaʻau, nā kiʻiʻoniʻoni hoʻolei, a pēlā aku. Ua lilo ka PP i mea koho, ʻoiai ke ʻimi nei ʻoe i kahi polymer me ka ikaika kiʻekiʻe (e laʻa, vs Polyamide) i nā noi ʻenekinia a i ʻole ke ʻimi wale nei i ka pono kumukūʻai i nā ʻōmole hoʻoheheʻe puhi (vs. PET).
