Melt Spinning Fiber ntau

Melt Spinning Fiber yog txheej txheem siv los tsim cov fibers los ntawm melting cov khoom polymer thiab extruding nws los ntawm qhov me me, hu ua spinnerets. Lub molten polymer yog ces solidified rau hauv fibers thaum nws txias thiab yog kos los yog stretched rau taw qhia cov polymer chains thiab ua rau kom lub zog thiab toughness ntawm lub resulting fibers.

Melt spinning yog cov txheej txheem dav siv los tsim cov khoom siv hluavtaws xws li polyester, nylon, thiab polypropylene. Cov fibers no tuaj yeem siv rau ntau yam kev siv xws li khaub ncaws, upholstery, ntaub pua plag, thiab fabrics industrial.

Cov txheej txheem melting pib los ntawm melting cov ntaub ntawv polymer, feem ntau nyob rau hauv lub hopper los yog lwm lub thawv uas yog rhuab mus rau ib tug kub kub. Lub molten polymer yog ces pub los ntawm ib tug spinneret, uas yog ib tug phaj los yog disk nrog me me qhov los ntawm cov polymer yog extruded. Raws li cov polymer dhau los ntawm lub qhov, nws yog txias los ntawm kev sib cuag nrog huab cua los yog lwm yam cua txias, uas solidifies lub polymer rau hauv fibers.

Cov fibers feem ntau yog kos los yog ncab los txhim kho lawv cov khoom siv kho tshuab. Qhov no yog ua los ntawm kev hla cov fibers los ntawm ib tug series ntawm rollers los yog lwm yam khoom siv kho tshuab uas ncab cov fibers thiab taw qhia cov polymer chains nyob rau hauv cov kev taw qhia ntawm lub fiber axis. Lub degree ntawm kev kos duab los yog ncab tuaj yeem tswj tau kom ua tiav cov khoom siv tshwj xeeb xws li tensile lub zog thiab elongation.

Zuag qhia tag nrho, Melt Spinning Fiber yog txheej txheem tseem ceeb rau kev tsim cov hluavtaws fibers nrog ntau yam khoom thiab kev siv. Los ntawm kev tswj cov ntaub ntawv, txheej txheem tsis, thiab cov kauj ruam tom qab ua tiav, cov tuam ntxhab tuaj yeem tsim cov fibers nrog cov khoom tsim kom tau raws li cov kev xav tau ntawm cov ntawv thov tshwj xeeb.
