The Quality Research Of Smectite Powder In Different Manufacturers

According to standards with montmorillonite powder as the research object in thispaper.Montmorillonite dispersed in different manufacturers for qualityinspection.Using two methods of comprehensive evaluation, to determine the qualityfit and unfit quality. The main contents are as follows:1、 This paper examines the34group of montmorillonite powder of15manufacturers, in accordance with the quality standards for testing. Includingpreparation, appearance evenness, silicon, aluminum, identification, X-ray diffractionexperiment, pH, particle size, adsorption, montmorillonite content of silicon dioxidecontent, Al2O3content, etc. The results show that Domestic montmorillonitecompared to montmorillonite preparation and thought close to exist certaindifferences in quality indicators. Therefore, whether Domestic montmorillonite canreplace imported montmorillonite raw materials, reduce cost, shorten the cycle, nowstill not feasible.2、This paper use the grey correlation analysis method and DTOPSIS method ofdifferent batch of montmorillonite powder manufacturer the multi-indexcomprehensive evaluation,.Studies have shown that two methods of analysis cancomprehensively judge of products, But two comprehensive evaluation methods ofjudging the results there exist certain differences.In the case of given the same weight,the differences between grey correlation method of batch is almost the same, Ci valuedifference obvious in DTOPSIS method to the evaluation results.It can react betterproduct quality.In the sample is large, DTOPSIS method is more applicable than greycorrelation method. Whether theoretical conclusion is proportional to the clinicaleffect, to be textual research of clinical research.3、Montmorillonite powder of15manufacturers were compliance.The result showthat the domestic montmorillonite powder were uneven. In several importantindicators, there was significant difference.
