I-calcium lignosulfonate i-ejenti yokunciphisa amanzi ikhishwa ku-pulp waste liquid.Imikhiqizo ihlukaniswe izigaba ezimbili, okungukuthi usawoti we-calcium nosawoti we-sodiumi-lignosulfonate, lena yakamuva itholwe ekucutshungulweni kwangaphambili.Ekwenziweni kwe-rayon noma embonini yephepha, lapho izinkuni ziphekwe ngokushisa okuphezulu nokucindezela okuphezulu, i-sulfite yengezwa ukuze ihlukanise i-cellulose ne-non-fiber okhunini, kanti i-cellulose etholakalayo iyimpahla eluhlaza ye-rayon, yokwenziwa. uvolo, iphepha, njll. I-non-cellulose encibilikisiwe esixazululweni yayibuswa yii-lignosulfonates ngenani elincane likashukela.
Lesi sixazululo sibizwa ngokuthi i-pulp waste.Ngemva kokukhishwa kotshwala nemvubelo oketshezini olulahlwayo, izinto ezisele zibe sezifuthwa ngomoya oshisayo ukuze zenze impushana ensundu.I-calcium lignosulfonateimpushana.Okuqukethwe kweI-calcium lignosulfonatecishe ku-45-50%, ukunciphisa izinto Okuqukethwe kungaphansi kuka-12%.
Okwamanje, isidingo emakethe fori-calcium lignosulphonathifuthi imikhiqizo yayo eguquliwe ikhula kancane kancane, okwenza ukuhlaziya kanye nokusetshenziswa kwe-lignin kanye nokuthola izinzuzo zezomnotho ezihambisana nayo kancane kancane kube ngokoqobo.Ngakho-ke, esikhathini esizayo, sizoqinisa ucwaningo nokuthuthukiswa kwezindlela ezintsha, ubuchwepheshe obusha kanye nezinqubo ezintsha ekuguqulwenii-calcium lignosulphonathiukuthuthukisa imikhiqizo ye-lignin enesidingo esikhulu semakethe, ukusebenza kahle kanye nezinzuzo ezinhle zezomnotho, kanye nokusheshisa ukusetshenziswa kwe-lignin ngezinga elikhulu.Izogqugquzela ukusetshenziswa ngokugcwele kwemithombo yemvelo evuselelekayo kanye nokuphathwa okuyisisekelo kokuhlanzwa nokukhipha uketshezi lwemfucuza yephepha.
I-Lignosulfonatei-ejenti yokunciphisa amanzi isetshenziswe ezweni lami iminyaka engu-40-50.Kodwa-ke, ngenxa yezinga eliphansi lokunciphisa amanzi, ukusetha kancane, ukunyuka okuncane kwamandla okucindezela ukhonkolo, namandla aphansi okuqala, ukusetshenziswa kwawo kukhonkolo kunqunyelwe.Kuphinde kuthinte ukuthuthukiswa kwevelu yayo.Okwamanje, I-calcium lignosulfonatei-ejenti yokunciphisa amanzi isasetshenziswa kakhulu ekwakhiweni kukakhonkolo ehlobo njengesinciphisi sikakhonkolo.Umhlaba ungakhiqiza amathani ayizigidi ezingama-30 we-lignin yezimboni minyaka yonke.Njengamanje, cishe amaphesenti angu-6 kuphela e-lignin yezimboni ezweni lami asetshenziswa, futhi iningi lamanye alahlwa emifuleni njengemfucuza.Ukungcolisa kakhulu imvelo.
Ukwenza kusebenze futhi kuyalungiswaI-calcium lignosulfonatefuthi ukuyihlanganisa ne-superplasticizer esekwe ku-naphthalene kungakha ukongiwa kokunciphisa amanzi okusebenza kahle kakhulu, futhi kunqobe ukushiyekaI-calcium lignosulfonate ukukhubazeka kanye namandla aphansi okuqala, futhi kunciphisa kakhulu i-superplasticizer esekwe yi-naphthalene.kubiza futhi andise ububanzi besicelo se-calcium yokhuni.
