ʻO Preperse PET grade nā mea hoʻomākaukau puaʻa i ʻōlelo ʻia no nā noi PET me ka polyester fiber masterbatch, PET film master-batch.ʻO nā puaʻa PET Preperse kekahi i loko o nā ʻano granular.He lepo ʻole lākou, kahe manuahi a kūpono no ka hānai ʻana.
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.
I mea e hoʻokō ai i ke koi FPV no nā noi koʻikoʻi, pono ka twin-screw extruder a me ka hana ʻana i ka mono masterbatch.ʻO ka FPV maʻamau o Preperse PET grade ≤ 0.8 bar / g, ma muli o ke kūlana ma lalo: Helu Mesh: 1400;Pigment maʻiʻo pili: 60g;Pigment% i ka resin: 8%.Ma luna o ka ʻikepili e pili ana i ka mono masterbatch i hana ʻia e twin-screw extruder.
