Viscose CHIKWANGWANI zimachokera pachilengedwe cellulose (zamkati hectometer) yaiwisi, kupota kachiwiri pambuyo chikasu asidi ester njira mu CHIKWANGWANI ndi regenerated mapadi CHIKWANGWANI.Popanga viscose fiber solidification process, tsitsani sodium hydroxide ndi sulfuric acid mu solidification bath reaction kuti mupange glauberite (sodium silicate powder).Potengera kuchira kwamadzi owonongeka, mtundu wa sodium sulphate womwe umachokera kumadzi otayira popanga silika wa viscose ndi wabwino.Lipoti loyang'anira khalidwe limasonyeza kuti ubwino wa viscose fiber by-product sodium sulfate ndi: kuyera bwino, zinthu zambiri zamtengo wapatali, zotsika za chloride ion, mtengo wotsika mtengo komanso mtengo wogula wogula;The kuipa kwa mankhwala ndi: chabwino tinthu kukula, zosavuta caking, PH mtengo acidic.Viscose fiber by-product ufa ndi yoyenera magalasi, mapepala ndi mafakitale ena akumunsi.
China ndiwopanga kwambiri ulusi wamankhwala komanso wopanga mwamphamvu pachitukuko.M'zaka zaposachedwa, mafakitale obwezerezedwanso a cellulose fiber m'dziko lathu amakhala makamaka ulusi, womwe umapanga pafupifupi matani 5 miliyoni.Malinga ndi ziwerengero za Yuanming ufa msika zidziwitso nsanja pagulu, kupanga sodium byproduct sulfate mu mankhwala CHIKWANGWANI makampani nkhani pafupifupi theka la okwana kupanga sodium byproduct sulphate m'dzikoli, amene ndi apamwamba mu mitundu yambiri ya sodium byproduct sulfate makampani. pakadali pano.
Ulusi waukulu wa viscose ndi wa ulusi wosinthika wa cellulose wachilengedwe, ndipo ulusi wa thonje ndi poliyesitala ndi wa zida zitatu zazikulu zopota za thonje.Amapangidwa ndi chilengedwe mapadi (zamkati) monga zofunika zopangira, kudzera mchere, ukalamba, sulfonation ndi njira zina mu sungunuka mapadi sulfonate, ndiye kusungunuka mu kuchepetsedwa lye kuti viscose, ndi chonyowa kupota ndi kupanga.
Malinga ndi ziwerengero, mu 2021, China ya viscose CHIKWANGWANI linanena bungwe anali 4.031 miliyoni matani, kuwonjezeka kwa 1.93% poyerekeza ndi 2020. Malinga ndi CHIKWANGWANI kutalika, viscose CHIKWANGWANI akhoza kugawidwa mu viscose staple CHIKWANGWANI ndi viscose filament.Mu 2021, kutulutsa kwa viscose staple fiber kunafika matani 3.87 miliyoni, ndikuwonjezeka kwa chaka ndi 2.12%;Kupanga ulusi wa viscose kunali matani 161,000, kutsika ndi 2.42% pachaka.
