The Performance Comprehensive Evaluation Of Desulfurization Gypsum Block

With the deepening of the wall material reform policy implementation,new wall materials constantly emerging,desulfurization gypsum as a kind of industrial by-product by a large number of accumulation,using it as a main raw material to produce the wall is gradually attention.Desulfurization gypsum block is a kind of new wall materials,its performance research is not a lot,the corresponding technical specification haven’t formulate.The paper through the trial production of the various properties of the block is analyzed,through access to relevant data,test and software calculates each performance index of the block,on the basis of the scientific and reasonable evaluation system of desulfurization gypsum block has carried on the comprehensive evaluation of performance.Detailed content is as follows:1)The desulfurization gypsum block production technology were described in detail,analyzing the composition of raw material composition and function,this paper expounds the production principle and technological process in detail,introduces the appearance of the block size,summarizes the production process all the important points.2)Desulfurization gypsum block as the research object,from the perspective of environmental protection,economy,technology,performance of block to conduct a comprehensive analysis,through the standard and the related literatures,laboratory test and related software calculation method,get block all aspects of the performance parameters,thus the new wall materials have a more objective understanding.3)Through the analysis of the usage of different evaluation method,combining the reality of wall materials block selection fuzzy analytic hierarchy process to comprehensive evaluation of the performance of wall material,reference evaluation index selection and other building materials,establishes an index system of wall materials,and through the query information and consulting experts in determining weights of different indexes.4)In accordance with national specifications and standards,standards of evaluation system have been developed based on actual performance indexes of wall materials,thus establishing a complete,comprehensive evaluation system for wall material,on this condition,the performances of desulfurization gypsum block have been evaluated comprehensively and two currently common wall materials have also been evaluated.Based on these evaluation results and contrastive analysis,suggestions have been made to follow-up studies of the performances of desulfurization gypsum block.Desulfurization gypsum block various performance analysis for this kind of new wall materials products provide certain basis,the promotion and performance improvement of the performance comprehensive evaluation of the results can give successive improvement production enterprises and scholars subsequent performance research provide reference.
