The zosungunulira ntchito youma gel osakaniza kupota nthawi zambiri decalin ndi otsika kuwira mfundo, mkulu kusakhazikika ndi kusungunuka kwabwino kwa UHMWPE. UHMWPE ndi decalin zimasakanizidwa mu njira yothetsera ndi ndende yosapitirira 10% mu mapasa-screw extruder, ndiyeno amatuluka kudzera mu spinneret kuti alowe mu ndime yotentha ya nayitrogeni kuchotsa zosungunulira. Pambuyo kuzirala, ulusi wa gel owuma umapangidwa, kenako ulusi wa UHMWPE umapangidwa ndi masitepe ambiri otambasulira mphamvu zotentha. Kuzungulira kwa gel owuma kumakhala kovuta mwaukadaulo ndipo kumafuna kusindikiza kwakukulu pamakina obwezeretsa, koma zabwino zake zimagona mu:
1. Njira yayifupi, zokolola zapamwamba komanso mtengo wotsika.
2. Zosungunulira zimatha kusinthidwa mwachindunji, zomwe zimathandiza kwambiri kuteteza chilengedwe.
3. Pazifukwa zina zomwezo, ulusi wokonzedwa ndi njira yowuma uli ndi crystallinity yapamwamba, makina opangira makina, kuchuluka kwa fiber komanso kukhazikika kwabwino kwa kutentha.
4. Ili ndi kuwala kwabwino, kumveka kofewa komanso zotsalira zosungunulira zochepa, ndipo ndizoyenera minda yamankhwala ndi nsalu zapakhomo. Pakadali pano, omwe amapanga zazikulu ndi DSM Company yaku Netherlands, TOYOBO Company yaku Japan, ndi Yizheng Chemical Fiber Company ya Sinopec.
Popanga kupota konyowa, mafuta oyera okhala ndi malo otentha kwambiri komanso osasunthika ochepa amagwiritsidwa ntchito ngati zosungunulira. Ufa wa Ultrahigh umasungunuka mu mafuta oyera kuti apange njira yozungulira. Ndiye, izo extruded mu madzi filament ndi kupota zigawo zikuluzikulu. Kenako, amaziziritsidwa mu osamba m'madzi kuti apange gel filament. Gel filament imachotsedwa, zouma ndi zowonongeka kuti zipangitse kalambulabwalo wosatambasulidwa, ndiyeno imatenthedwa kangapo kuti ipange ulusi womalizidwa. Ukadaulo waukadaulo wonyowa ndi wosavuta komanso umafunikira zida zochepa. Pakadali pano, mabizinesi am'nyumba ambiri amatengera njira yonyowa yopota, yomwe imatha kupanga zida zankhondo ndi anthu wamba zomwe zimakhala ndi manambala osiyanasiyana okana ndi mphamvu. Komabe, cholinga cha kafukufuku waposachedwa wa njira yonyowa ndikuwongolera njira yomwe ilipo, kupititsa patsogolo makina, kukhazikika ndi magwiridwe antchito a ulusi, kuyang'ana pazapakati komanso zotsika. Pakali pano, opanga kwambiri ndi Honeywell Company ku United States, Beijing Tongyizhong Company ku China, ndi Nantong Jiujiujiu Company.
