:54) ДОБАВКА В СЫРЬЕВОЙ ЦЕМЕНТНЫЙ ШЛАМ: 54) ADDITION TO RAW CEMENT SLEEP
1one
Изобретение относитс к строителным материалам, а именно к производству цемента.The invention relates to building materials, namely, to the production of cement.
Известны наиболее близкие к изобретению по технической сущности и достигаемому эффекту добавки дл снижени влажности цементных шламов , включающие лигносульфонат .The closest to the invention in technical essence and the effect achieved are additives for reducing the moisture content of cement slurries, including lignosulfonate.
Однако ввод таких добавок в дементный сырьевой .шлам, содержащийв качестве одного из компонентов золу-унос, не предотвращает расслоени шлама, возникающего вследствие седиментации зольных частиц.However, the introduction of such additives into the demental raw sludge, containing as one of the components the fly ash, does not prevent the separation of the sludge resulting from the sedimentation of the ash particles.
Цель изобретени - предотвращение расслоени шлама при сохранении разжижающего эффекта.The purpose of the invention is to prevent the separation of sludge while maintaining a diluting effect.
Достигаетс это тем, что добавка в сырьевой . цементный шлам,содержащий золу-унос, включающа лигносульфонат , дополнительно содержит алкилсульфонат при следующем соотношении компонентов, вес.%: лигносульфонат 50-85, алкилсульфонат 15-50.This is achieved by the fact that the additive in the raw material. cement slurry containing fly ash, including lignosulphonate, additionally contains alkylsulphonate in the following ratio of components, wt%: lignosulphonate 50-85, alkylsulphonate 15-50.
Предотвращаетс седиментаци шлама вследствие того, что алкилсульфонаты представл ют собой полимер , содержащий по всей длине це2Sludge sedimentation is prevented due to the fact that alkyl sulfonates are a polymer that contains
почки большое число активных центров .kidneys a large number of active centers.
При адсорбции алкилсульфонатов на зольной частице активные центры, обращенные к жидкой фазе, создают вокруг зольной частицы диффузный слой им мобилизованной воды, преп тствующий седиментации.During the adsorption of alkyl sulfonates on the ash particle, the active centers facing the liquid phase create a diffuse layer around them of the ash particle and mobilized water, which prevents sedimentation.
в то же врем разжижающий эффект от использовани лигносульфоната при введении алкилсульфоната сохран етс .At the same time, the diluting effect of the use of lignosulfonate with the introduction of alkyl sulfonate remains.
Пример. Готов т сырьевой цементный шлам,-характеризующийс КН 0,91; ,16и р 1,18, СО-, держащий 81 вес.% мела и 19 вес.% золы уноса. Добавку ввод т в шламExample. Raw cement slurry is prepared, characterizing KH 0.91; , 16 and p 1.18, CO-, holding 81% by weight of chalk and 19% by weight of fly ash. The additive is introduced into the sludge
в количестве 0,2% от массы сухого шлама, а затем довод т шлам до посто нной растекаемости, равной 55 мм. Седиментационную устойчивость шлама оценивают по толщине осадка вin the amount of 0.2% by weight of dry sludge, and then bring the sludge to a constant flowability of 55 mm. The sedimentation stability of the sludge is estimated by the thickness of the sediment in
мм после 24 ч выдержки в мерном цилиндре без перемешивани .mm after 24 hours in the measuring cylinder without mixing.
