Calcium lignosulfonate mvura inoderedza mumiririri inotorwa kubva mumarara tsvina yemvura.Zvigadzirwa zvakakamurwa kuita mapoka maviri, anoti calcium munyu uye sodium munyu welignosulfonate, iyo yekupedzisira yakawanikwa kubva pakugadziriswa kwekare.Mukugadzira rayon kana muindasitiri yemapepa, kana huni hukabikwa nekupisa kwakanyanya uye kudzvanywa, sulfite inowedzerwa kuti iparadzanise cellulose uye isiri-fiber muhuni, uye iyo yakawanikwa cellulose ndiyo yakabikwa rayon, yakagadzirwa. mvere dzemakwai, mapepa, nezvimwewo. Iyo isiri-cellulose yakanyungudutswa mumushonga yaitongwalignosulfonates neshuga shoma.
Mushonga uyu unonzi pulp waste.Mushure mekunge doro nembiriso zvabviswa kubva mumarara, zvinhu zvinenge zvasara zvinozopfapfaidzwa nemhepo inopisa kuita hupfu hwebrown, hunova.calcium lignosulfonateupfu.Zviri mukati mecalcium lignosulfonateinenge 45-50%, kuderedza zvinhu Zvinyorwa zvishoma pane 12%.
Parizvino, kudiwa kwemusika kwecalcium lignosulphonateuye zvigadzirwa zvaro zvakagadziridzwa zviri kuwedzera zvishoma nezvishoma, zvichiita kuti kuongororwa uye kushandiswa kwe lignin uye kuwana hupfumi hunoenderana nehupfumi kubva pazviri zvishoma nezvishoma kuve chokwadi.Naizvozvo, mune ramangwana, isu tichasimbisa kutsvagisa nekuvandudzwa kwemaitiro matsva, matekinoroji matsva uye maitiro matsva mukugadzirisacalcium lignosulphonatekugadzira zvigadzirwa zve lignin zvine kudiwa kwemusika wakakura, kuita kwakanaka uye mabhenefiti akanaka ehupfumi, uye nekumhanyisa kushandiswa kwakakura kwe lignin.Ichasimudzira kushandiswa kuzere kwezvinhu zvakasikwa zvinogonekazve uye manejimendi ekutanga e pulp uye mapepa tsvina yemvura kunatswa uye kuburitsa.
Lignosulfonatemvura yekudzikisa mumiririri yakashandiswa munyika yangu kwemakore 40-50.Nekudaro, nekuda kwekuderera kwayo kwemvura yekudzikisa mwero, kunonoka kudzika, kuwedzera kudiki kwesimba rekumanikidza rekongiri, uye kuderera kwesimba rekutanga, kushandiswa kwayo mukongiri kunogumira.Zvinokanganisawo kuvandudzwa kwekukosha kwayo.Parizvino, calcium lignosulfonatemvura yekudzikisa mumiririri ichiri kunyanya kushandiswa muzhizha kongiri kuvaka sekongiri retarder.Nyika inogona kugadzira 30 miriyoni matani eindasitiri lignin gore rega rega.Parizvino, ingangoita 6% chete yeindasitiri lignin munyika yangu inoshandiswa, uye mazhinji akasara anoiswa munzizi semarara.Kusvibisa zvakakomba zvakatipoteredza.
Activating uye kugadzirisacalcium lignosulfonateuye kuisanganisa ne naphthalene-based superplasticizer inogona kugadzira yakakwirira-inoshanda-inoderedza kuchengetedza kwemvura, uye kukunda kukanganisa kwecalcium lignosulfonate's kunonoka uye kuderera kwekutanga simba, uye kuderedza zvakanyanya naphthalene-based superplasticizer.mutengo uye kuwedzera chiyero chekushandiswa kwehuni calcium.
