Ni irihe tandukaniro riri hagati yiziga rya polyurethane ninziga ya nylon？

1. Ibikoresho by'ibiziga bya polyurethane biroroshye cyane, hamwe no guhangana neza no gutera urusaku;mugihe ibiziga bya nylon bigoye cyane, kandi guhangana kwabo gutandukanye biratandukanye gato na polyurethane.Kurugero, imyenda ikozwe muri nylon nayo irwanya kwambara.

2. Ibikoresho byinziga za polyurethane niziga rya nylon biratandukanye.Polyurethanes itunganijwe kuva muri isocyanates (monomers) hamwe na hydroxyl.Bitewe nitsinda rikomeye rya karbamate, idashobora gukomera mumatsinda adafite inkingi, ifite amavuta meza yo guhangana, gukomera, kwambara nabi, kurwanya gusaza no gufatira hamwe.Ibikoresho bikwiranye nubushyuhe bugari (-50 kugeza 150 ° C) birashobora gutegurwa bivuye mubikoresho bitandukanye, harimo elastomers, resimoplastique hamwe na resmosetting.Ntabwo irwanya hydrolysis ku bushyuhe bwinshi, cyangwa uburyo bwa alkaline.Nylon ni ijambo rusange kuri polymers zirimo amide amatsinda mugice gisubiramo urunigi nyamukuru rwa macromolecular.Polyamide irashobora gutegurwa no gufungura impeta ya polymerisation ya lactam, cyangwa na polycondensation ya diamine na acide dibasic.
