YIHOO PA (polyamide) polymerization & hoʻololi nā mea hoʻohui
ʻO Polyamide (i kapa ʻia ʻo PA a i ʻole Nylon) nā huaʻōlelo generic o ke kēpau thermoplastic, i loaʻa ka pūʻulu amide i hana ʻia ma ke kaulahao molekiola nui. Pākuʻi ʻia ʻo PA i nā PA aliphatic, aliphatic - PA ʻaʻala a me PA ʻala, kahi PA aliphatic, i lawe ʻia mai ka helu o nā ʻāpana kalapona i loko o ka monomer synthetic, he nui nā ʻano, ka hiki a me ka noi nui.
Me ka miniaturization o nā kaʻa, ka hana kiʻekiʻe o nā pono uila a me nā pono uila, a me ka wikiwiki o ke kaʻina māmā o nā pono mīkini, e ʻoi aku ka kiʻekiʻe o ka noi no ka nylon. ʻO nā hemahema maoli o ka Nylon kekahi mea nui e kaupalena ana i kāna noi, no ka PA6 a me PA66, ke hoʻohālikelike ʻia me nā ʻano PA46, PA12, loaʻa ke kumu kūʻai ikaika, ʻoiai ʻaʻole hiki i kekahi hana ke hoʻokō i nā koi o ka hoʻomohala ʻana i nā ʻoihana pili.
