Kodi magulu akuluakulu a polypropylene ndi ati?

Mitundu ya ulusi wa polypropylene ndi monga ulusi (kuphatikiza undeformed filament ndi bulk textured filament), ulusi waufupi, bristle, ulusi wogawanika, ulusi wocheperako, ulusi wa profiled, ulusi wophatikizika wosiyanasiyana ndi nsalu zosawomba.Amagwiritsidwa ntchito kwambiri popanga makapeti (kuphatikiza nsalu zoyambira pa carpet ndi suede), nsalu zokongoletsera, nsalu zapampando, zingwe zosiyanasiyana, mikwingwirima, maukonde asodzi, zomverera zothira mafuta, zida zomangira, zida zonyamula katundu ndi nsalu zamakampani, monga nsalu zosefera ndi thumba nsalu.Kuphatikiza apo, amagwiritsidwa ntchito kwambiri pazovala, ndipo amatha kuphatikizidwa ndi ulusi wosiyanasiyana kuti apange mitundu yosiyanasiyana ya nsalu zophatikizika.Pambuyo kuluka, zikhoza kupangidwa kukhala malaya, malaya, masewera, masokosi ndi zina zotero.Chophimba chopangidwa ndi polypropylene hollow fiber ndi chopepuka, chofunda komanso chotanuka.

kapangidwe

Polypropylene ilibe magulu a mankhwala omwe angaphatikize ndi utoto mu mawonekedwe a macromolecular, kotero kuti utoto ndizovuta.Nthawi zambiri, kukonzekera kwa pigment ndi polypropylene polima zimasakanizidwa mofanana mu screw extruder ndi njira yosungunulira, ndipo ulusi wamtundu womwe umapezedwa ndi kusungunula umakhala wothamanga kwambiri.Njira ina ndi copolymerization kapena kumezanitsa copolymerization ndi acrylic asidi, acrylonitrile, vinilu pyridine, etc., kuti magulu polar akhoza anadzetsa mu macromolecules polima, ndiyeno utoto mwachindunji ndi njira ochiritsira.Popanga polypropylene, nthawi zambiri pamafunika kuwonjezera zowonjezera zosiyanasiyana kuti zitheke kuwongolera utoto, kukana kuwala komanso kukana moto.
