ʻIke Nui no ka Polycarbonate
ʻO ka polycarbonate kahi mea lōʻihi. ʻOiai he kiʻekiʻe kona hopena-kūʻai, he haʻahaʻa ka pale ʻana.
No laila, hoʻohana ʻia kahi uhi paʻakikī i nā lens maka maka polycarbonate a me nā ʻāpana kaʻa waho polycarbonate. Hoʻohālikelike ʻia nā hiʻohiʻona o ka polycarbonate me nā polymethyl methacrylate (PMMA, acrylic), akā ʻoi aku ka ikaika o ka polycarbonate a paʻa i ka lōʻihi a hiki i ka wela wela. ʻO nā mea i hoʻohana ʻia i ka wela ka mea maʻamau i ka amorphous, a ma muli o ka hopena, ʻike maopopo ʻia i ke kukui ʻike ʻia, me ka hoʻouna ʻana i ka māmā ma mua o nā ʻano aniani he nui.
ʻO ka polycarbonate ka mahana hoʻololi aniani ma kahi o 147 °C (297 °F), no laila e palupalu mālie ma luna o kēia wahi a kahe ma luna o 155 °C (311 °F). Pono e mālama ʻia nā mea hana ma nā wela kiʻekiʻe, ma luna o 80 °C. (176 °F) no ka hana ʻana i nā huahana me ke koʻikoʻi ʻole. ʻOi aku ka maʻalahi o ka hoʻoheheʻe ʻia ʻana o nā māka molekala haʻahaʻa ma mua o nā māka kiʻekiʻe, akā haʻahaʻa ko lākou ikaika ma muli o ka hopena. Loaʻa i nā māka paʻakikī ke kiʻekiʻe o ka molecular mass, akā ʻoi aku ka paʻakikī o ka hana.
