【摘要】：本文主要对云南磷建筑石膏缓凝剂方案进行优选,获得最佳的缓凝剂方案,延长云南磷建筑石膏的凝结时间,提高其再利用率。本文主要采用的研究方法如下:1)试验分析法。探究了缓凝剂对云南磷建筑石膏性能(初、终凝结时间、抗压强度和抗折强度)的影响。2)价值工程与层次分析法相结合。一方面定性与定量相结合来确定各指标权重,另一方面,对缓凝剂优选时实现技术与经济相结合,使得优选结果更准确。本文具体的研究内容如下:1)选取酒石酸、硫脲、聚乙烯醇和骨胶四种缓凝剂,通过研究酒石酸、硫脲、聚乙烯醇和骨胶四中缓冲剂对云南磷建筑石膏的性能的影响,并利用Origin软件对试验数据进行处理。2)以云南磷建筑石膏不同缓凝剂进行优选为总目标层,对其内容进行层层分解,不仅考虑其凝结时间、力学性能,也同时考虑其环境性能、操作性能因素,将目标层分为一级指标层;后对一级指标层进行分析,得到相对应的二级指标层,通过对总目标层、一级指标层、二级指标层的建立来构建缓凝剂优选评价体系。3)在试验数据及构建缓凝剂优选评价体系的基础上,采用价值工程与层次分析法相结合的方法来完成缓凝剂的优选。首先利用层次分析法确定各指标的权重,后计算各缓凝剂方案的价值指数,通过对比,确定最佳方案。通过以上分析,掺量为0.4%的骨胶缓凝剂方案价值系数最高,确定其为云南磷建筑石膏缓凝剂的最佳方案。
[Abstract]:In this paper, Yunnan phosphorus building gypsum retarder scheme is selected, the best retarder scheme is obtained, and the setting time of Yunnan phosphorous building gypsum is prolonged. The main research methods adopted in this paper are as follows: 1) Experimental analysis method. The performance of retarder for phosphogypsum in Yunnan was investigated (initial and final setting time). Impact of compressive strength and flexural strength. 2) value engineering is combined with AHP. On the one hand, qualitative and quantitative analysis is combined to determine the weight of each index, on the other hand. In this paper, we select tartaric acid, thiourea, polyvinyl alcohol and bone glue to select tartaric acid, thiourea, polyvinyl alcohol and bone glue. The effects of tartaric acid, thiourea, polyvinyl alcohol and bone glue on the properties of Yunnan phosphogypsum were studied. Origin software is used to process the test data. 2) Yunnan phosphogypsum retarder is selected as the total target layer, and its content is decomposed layer by layer, not only its setting time is considered. The target layer is divided into the first level index layer by taking into account the environmental performance and the operational performance factors. After the analysis of the first level of indicators, the corresponding secondary index layer, through the total target layer, the first level of indicators. The establishment of the secondary index layer to build a retarder selection evaluation system. 3) on the basis of the test data and the establishment of the evaluation system of the excellent selection of retarder. The method of combining value engineering with analytic hierarchy process (AHP) is used to select retarder. Firstly, the weight of each index is determined by AHP, then the value index of each retarder scheme is calculated and compared. Through the above analysis, the value coefficient of the bone glue retarder with the dosage of 0.4% is the highest, and it is the best scheme for the gypsum retarder in Yunnan phosphorous building.
