Kuthamanga Kwambiri Kuthamanga kwa Polyamide Resin Ntchito
Liwiro lozungulira giredi PA6 pellet of low viscosity yokhala ndi magwiridwe antchito okhazikika a gulu lililonse.
Makhalidwe a mankhwala
Kuthamanga kwambiri kupota kwa kalasi ya nylon6 kusungunula kusungunula, kutambasula, kulembera malemba ndi njira zina kuti apange ulusi wokhazikika (POY), ulusi wokoka bwino (FDY), wojambula ndi wopunduka (DTY) ndi zinthu zina zopota za nayiloni. Polyamide chifukwa cha kulimba kwake, kukhazikika bwino komanso kukana kuvala bwino kuposa mitundu ina ya ulusi, imagwiritsa ntchito kwambiri zovala monga jekete, zovala zosambira, zovala zomangira, kuvala kwa yoga ndipo imakhala ndi magwiridwe antchito abwino kwambiri, imakwaniritsa zosowa za ogula.
Ubwino: Ili ndi utoto wabwino kwambiri komanso zinthu zabwino zopindika, zopangidwa munsalu yofewa komanso yogwirizana ndi khungu yokhala ndi kukana kwambiri komanso kulimba mtima.

Kugwiritsa ntchito mankhwala
POY
Wothamanga kwambiri wopota giredi PA6 utomoni wosungunula wozunguliridwa ndi spinneret kenako utakhazikika kuti upange POY. Nylon POY imakhala yokhazikika kwambiri, imakhala ndi kukhathamira pang'ono komanso kucheperachepera, yolimbana ndi kutentha kwambiri, yomasuka kukhudza komanso sheen wofatsa, imagwiritsidwa ntchito ngati zida za DTY (Drawn Deformed Yarn).
Mtengo wa FDY
Polyamide utomoni wopota wothamanga kwambiri wopangidwa mu ulusi wokokedwa bwino (FDY) ukasungunuka, kupota, kuzizira ndi kutambasula. Ulusi wokokedwa bwino (FDY) poyerekeza ndi ulusi wolunjika (POY), umakhala ndi kutsika pang'ono ndi kuchepa, ndipo ukhoza kugwiritsidwa ntchito mwachindunji kumtunda wapansi. Nthawi zambiri amagwiritsidwa ntchito ngati zopangira nsalu monga zosambira ndi jekete pansi.
DTY
Tensile textured ulusi (DTY) amapangidwa ndi ulusi wolunjika kale (POY) kudzera mu njira yotambasula. Imakhala ndi kukhuthala ndi kuchepa, mpweya wabwino komanso ulusi wofewa, umakwaniritsa zofunikira pakuluka kumtunda ndipo nthawi zambiri amagwiritsidwa ntchito popanga zovala za yoga, zovala za ana ndi nsalu zina.
Sinolong makamaka chinkhoswe mu R&D, kupanga ndi kugulitsa polyamide utomoni, mankhwala monga BOPA PA6 utomoni, co-extrusion PA6 utomoni, mkulu-liwiro kupota utomoni PA6, mafakitale silika utomoni PA6, engineering pulasitiki PA6 utomoni, co-PA6 utomoni, mkulu kutentha polyamide PPA utomoni ndi mndandanda wa mankhwala. Zogulitsazo zimakhala ndi ma viscosity osiyanasiyana, kugawa kwamafuta okhazikika, makina abwino kwambiri komanso magwiridwe antchito abwino. Amagwiritsidwa ntchito kwambiri mufilimu ya BOPA, filimu ya nayiloni co-extrusion, kupota kwa boma, kupota kwa mafakitale, ukonde wausodzi, chingwe chapamwamba cha nsomba, magalimoto, magetsi ndi magetsi. Zina mwa izo, kuchuluka kwa kupanga ndi kutsatsa kwazinthu zama polyamide zapamwamba kwambiri zamakanema zili m'malo otsogola. Mafilimu apamwamba kwambiri a polyamide resin.
