ʻO nā huahana Preperse PA nā mea hoʻomākaukau puaʻa o nā puaʻa kūlohelohe no ka polyamide a me ka poly-amide 6. ʻO nā pua pua Preperse PA i loko o nā ʻano granular.He lepo ʻole lākou, kahe manuahi a kūpono no ka hānai ʻana.
ʻO ke kiʻekiʻe o ka hoʻopuehu ʻana o nā puaʻa i loko o ka mea lawe polymer ka hopena i ka hana maikaʻi maikaʻi loa, ʻoi loa no ka noi ʻana i nā noi i loko o nā molding injection, extrusion a me nā fibers.
ʻO ka haʻahaʻa haʻahaʻa o nā mea lawe polymer i hoʻohana ʻia he hopena maikaʻi ma nā waiwai rheological o ka polymer melt a me nā waiwai ʻenehana o nā huahana hope loa, e like me ka ikaika tensile ʻoi aku ka maikaʻi a me ka elongation rate o nā fibers a me nā yarns.ʻO nā waiwai wikiwiki o nā puaʻa i koho ʻia e ʻae i ka hoʻohana ʻana i ke ao holoʻokoʻa ʻoiai i nā mea i koi ʻia i nā kūlana wikiwiki loa.
