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
Liwiro lothamanga kwambiri la nylon6 resin kudzera kusungunula kusungunula, kutambasula, kutumizirana mameseji ndi njira zina zopangira ulusi wolunjika (POY), ulusi wokokedwa bwino (FDY), wokoka komanso wopunduka (DTY) ndi zinthu zina zopota za nayiloni.Polyamide chifukwa cha kulimba kwake, kukhathamira kwabwino komanso kukana kuvala bwino kuposa ulusi wamitundu ina, imagwiritsidwa ntchito kwambiri pazovala ngati jekete, zovala zosambira, zomangira zovala, kuvala kwa yoga ndipo zimakhala ndi magwiridwe antchito abwino kwambiri, zimakwaniritsa zosowa za ogula.
Ubwino: Ili ndi utoto wabwino kwambiri komanso zinthu zabwino zopindika, zopangidwa munsalu yofewa komanso yapakhungu 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 kutha msinkhu komanso kucheperachepera, kopanda kutentha kwambiri, kumasuka kukhudza komanso kunyezimira pang'ono, nthawi zambiri imagwiritsidwa ntchito ngati zida za DTY (Drawn Deformed Yarn).
Mtengo wa FDY
Polyamide utomoni wopota wothamanga kwambiri wopangidwa kukhala ulusi wokokedwa bwino (FDY) ukasungunuka, kupota, kuzizira ndi kutambasula.Ulusi wokokedwa bwino (FDY) poyerekeza ndi ulusi wolunjika (POY), umakhala ndi kutsika pang'ono komanso kuchepera, ndipo ukhoza kugwiritsidwa ntchito mwachindunji pakuluka kumtunda.Nthawi zambiri amagwiritsidwa ntchito ngati zopangira nsalu monga zosambira ndi jekete pansi.
DTY
Ulusi wokhazikika (DTY) umapangidwa ndi ulusi womwe umakhala wolunjika (POY) kudzera munjira yotambasula.Lili ndi kutha msinkhu komanso kuchepa, mpweya wabwino komanso ulusi wofewa, umakwaniritsa zofunikira za kuluka kwapansi ndipo zimagwiritsidwa 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 kwamphamvu kwa maselo, 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.
