The solvent inoshandiswa kuomesa gel kuruka inowanzo decalin ine yakaderera kuvira poindi, yakakwirira kunyungudika uye yakanaka solubility yeUHMWPE. UHMWPE uye decalin zvinosanganiswa mukugadzirisa nekugadzirisa kusingapfuuri 10% mu-twin-screw extruder, uye zvino inobudiswa kuburikidza ne spinneret kuti ipinde mumhepo inopisa nitrogen kubvisa zvinonyungudutsa. Mushure mekutonhora, yakaoma gel filaments inoumbwa, uye ipapo UHMWPE fiber inogadzirwa ne-multi-stage yakakwirira simba rinopisa rinotambanudza. Iyo yakaoma gel kutenderera maitiro inonetsa yakaoma uye inoda kuvharwa kwepamusoro kweiyo yekudzoreredza sisitimu, asi mabhenefiti ayo anonyanya kurara mu:
1. Shorter process, yakakwirira kugadzirwa uye yakaderera mutengo.
2. The solvent inogona kushandiswa zvakananga zvakare, iyo inobatsira zvikuru kuchengetedzwa kwezvakatipoteredza.
3. Pasi pemamwe mamiriro akafanana, mafiber akagadzirirwa nenzira yakaoma ane yakakwirira crystallinity, mechanical properties, yakakwirira fiber density uye zviri nani kupisa kugadzikana.
4. Iine kupenya kwakanaka, kunzwa kwakanyorova uye yakaderera solvent residu, uye inokodzera minda yekurapa uye yemba yemachira. Parizvino, vagadziri vakuru ndiDSM Kambani yeNetherlands, TOYOBO Kambani yeJapan, uye Yizheng Chemical Fiber Kambani yeSinopec.
Mukunyorova kutenderera kwekugadzira maitiro, mafuta machena ane yakakwira yekubikira poindi uye yakaderera volatility inoshandiswa se solvent. Ultrahigh hupfu inonyungudutswa mumafuta machena kuita spinning stock solution. Zvadaro, iyo inobudiswa mukati memvura filament nekutenderera zvikamu. Zvadaro, inotonhodzwa mumvura yekugezera kuti iite gel filament. Iyo gel filament inobviswa, yakaomeswa uye yakaparadzwa kuti iite precursor isina kutambanudza, uye zvino inopisa yakatambanudzwa kakawanda kuti iite fiber yakapera. Iyo tekinoroji yekunyorova haina kuoma uye inoda midziyo mishoma. Parizvino, mabhizinesi mazhinji epamba anotora nzira yekunyorova, iyo inogona kugadzira zvigadzirwa zvechiuto uye zvechivanhu fiber zvine huwandu hwakasiyana hwekuramba uye masimba. Nekudaro, iyo inotarisisa yeazvino wet process nzira yekutsvaga ndeyekugonesa iripo nzira nzira, kuwedzera kuvandudza ma mechanic zvivakwa, kugadzikana uye kushanda kwefiber, kutarisa kune yepakati uye yakaderera-yekupedzisira zvigadzirwa. Parizvino, vagadziri vakuru iHoneywell Company iri muUnited States, Beijing Tongyizhong Company iri kuChina, neNantong Jiujiujiu Company.
