Iwe unoziva here kushandiswa kwePolyamide (PA) manyadzo mune njanji yekufambisa?
Njanji rejira rinoreva kushandiswa kwechitima zvekufambisa zvechitima, kusanganisira mitezo yemutengesi, kuchengetedza kwenyonganiso, kuchengetedzwa kwenyika, kunoonekwa serimwe nzira yekugadzirisa matambudziko emigwagwa mukati uye pakati pamaguta mune ramangwana.
Polyamide, inowanzozivikanwa seNylon, ine zvivakwa zvakanaka zvemagetsi, kupokana nekuomesesa, kupokana, kupfeka kurwisa, kuzvishingisa, kuramba kwemakemikari uye kuumbwa. Polyamide composite zvinhu zvinoshandiswa mune njanji yekufambisa inogona kugadzirisa matambudziko akadai seyakagadzikana jitter, inoderedza nguva yekuchengetedza, iyo yakakosha kuti ive nechokwadi chekushanda kwakanyanya kwekumhanya-simpot. Mapuranga emapuranga anoshandiswa zvakanyanya mujira rekutenderera.
