Industrial High Tenacity Polyamide Nylon N6 Multifilament FDY DTY POY Ulusi Ulusi

Polyamide (PA), yomwe imadziwika kuti Nylon fiber ndiye ulusi woyamba wopangidwa padziko lonse lapansi ndipo ndi ulusi wapulasitiki wopangidwa ndi thermoplastic wokhala ndi makina abwino kwambiri.Mamolekyu a nayiloni ali ndi -CO- ndi -NH- magulu, omwe amatha kupanga zomangira za haidrojeni pakati kapena mkati mwa mamolekyu, ndipo amathanso kuphatikizidwa ndi mamolekyu ena.Chifukwa chake, nayiloni imakhala ndi mphamvu yabwino yoyamwitsa chinyezi ndipo imatha kupanga mawonekedwe abwinoko a crystalline.

Polyamide (PA) Ulusi wa nayiloni uli ndi kukana kwa alkali wabwino, koma kukana kwa asidi.Pansi pa kutentha kwa chipinda, imatha kupirira 7% hydrochloric acid, 20% sulfuric acid, 10% nitric acid, ndi 50% caustic soda kotero kuti polyamide fiber ndi yoyenera zovala zogwirira ntchito zotsutsana ndi dzimbiri.Kuphatikiza apo, itha kugwiritsidwa ntchito ngati ukonde wophera nsomba chifukwa cha kukana kukokoloka kwa madzi a m'nyanja.Moyo wa maukonde osodza opangidwa ndi Polyamide (PA) ulusi wa nayiloni ndi wautali kuwirikiza 3 mpaka 4 kuposa maukonde wamba asodzi.

Chifukwa cha mphamvu zake zazikulu, kukana kwake komanso kukana kwabwino kwa abrasion, ma mileage a polyamide a zingwe zamatayala opangidwa kukhala matayala ndi okwera kuposa zingwe wamba za matayala a rayon.Pambuyo poyesedwa, matayala a tayala a polyamide amatha kuyenda pafupifupi 300,000km, pomwe matayala a rayon amatha kuyenda pafupifupi 120,000 km.Chingwe chomwe chimagwiritsidwa ntchito mu chingwe cha matayala chimakhala ndi mphamvu zambiri, modulus yapamwamba komanso kukana kutopa.Chifukwa cha mgwirizano wa ma molekyulu a polyamide mumpangidwe wopindika, nayiloni 66 ndi nayiloni 6 ndi ma polyamides.Mphamvu zenizeni ndi modulus za fiber zimangofikira 10% ya mtengo wamaganizo.

Mphamvu yosweka ya ulusi wa polyamide ndi 7 ~ 9.5 g / d kapena kupitilira apo, ndipo kusweka kwa kunyowa kwake kumakhala pafupifupi 85% ~ 90% ya iyo muuma.Polyamide (PA) Fiber ya nayiloni imakhala ndi kukana kutentha komwe kumasanduka chikasu pambuyo pa maola 5 pa 150 ℃ Celsius, imayamba kufewa pa 170 ℃ ndikusungunuka pa 215 ℃.Kutentha kwa kutentha kwa nayiloni 66 kuli bwino kuposa nayiloni 6. Kutentha kwake kotetezeka ndi 130 ℃ ndipo motsatira.90 ℃.Ulusi wa polyamide uli ndi kukana kwabwino kwa kutentha kochepa.Ngakhale atagwiritsidwa ntchito pa kutentha kochepa kwa 70 ℃, kuchira kwake sikumasintha kwambiri.

M'mafakitale, polyamide (PA) ulusi wa nayiloni ukhoza kugwiritsidwa ntchito ngati maukonde asodzi, nsalu zosefera, zingwe, nsalu zamatayala, mahema, malamba otumizira, nsalu zamakampani, ndi zina zambiri ndipo amagwiritsidwa ntchito ngati ma parachuti ndi nsalu zina zankhondo poteteza dziko.
