3results about How to "Good mixing performance" patented technology

This application provides a structural simulation analysis method and apparatus based on carboxymethyl cellulose multi-component mixing. The method includes: constructing multiple multi-component mixing models with the same external dimensions but different internal structures; performing fluid dynamics simulation on each multi-component mixing model to simulate the mixing process of multiple fluids and obtaining the corresponding mixing results; and determining the multi-component mixing model with the optimal mixing effect based on comparative analysis of the mixing results. This application, by constructing and simulating multiple multi-component mixing models with different internal structures in parallel and comparing and analyzing their mixing results based on fluid dynamics principles, can quickly and objectively select the mixing model with the optimal mixing efficiency.

This invention discloses a mine backfill cementitious material and its preparation method. The mine backfill cementitious material of this invention comprises the following components in the following mass ratios: high belite sulfoaluminate cement clinker: 3-8 wt%; high free calcium silicate cement clinker: 1-3 wt%; granulated blast furnace slag powder or granulated blast furnace slag: 74-85 wt%; gypsum: 10-18 wt%. Compared with other paste-like backfill materials of the same strength, the cementitious material of this invention solves the problems of poor activation effect, poor mechanical properties affecting the mine backfilling effect, and high cost due to large amount of cementitious material used in existing mine backfill cementitious materials. At the same time, it not only reduces the proportion of cementitious material used, but also fully meets the requirements of mine backfilling projects.
