摘　　要：采用聚乙烯醇乳液和聚羧酸对脱硫建筑石膏进行改性,对其改性后的强度和吸水率进行了试验研究,结果表明,聚乙烯醇乳液和聚羧酸对脱硫建筑石膏的强度和防水性具有一定的影响,同时掺加聚乙烯醇乳液和聚羧酸能够较好地提高脱硫建筑石膏的强度和防水性能,掺加4%聚乙烯醇乳液和3%聚羧酸时脱硫建筑石膏性能较优;利用扫描电子显微镜对试样进行了微观分析,探讨了聚合物对脱硫建筑石膏的作用机理,提出了固结模型。Adopt PVA emulsion and polycarhoxylate to improve the performance of desulfurization building gypsum. The result shows that PVA emulsion and polycarboxylate can improve the strength and reduce the water absorption of desulfurization building gypsum, spike them together can get better results. Add 4 % PVA emulsion and 3 % the polycarboxylate to desulfurization building gypsum can get better performance. The electron microscope is used to analyze and research the mechanism and consolidation model of polymer in desulfurization building gypsum.
