Research Of Ultrafine Liquid Solid Explosive Separation Techniqu And Its Agglomeration Repressive Mechanism

Thins paper has comprehensively analyzed the advancement ofultrafine powder liquid solid separation technique home and abroad, andcombing the actual need of post processing art of ultrafine singlematerial explosive jet crystal, invented a set of stainless steel sandfiltering and washing device, having successfully solved the poserswhich the conventional filters can' t and effectively eliminated thecrystal-bridge caused by the existence of solvent, meanwhile, designeda set of circulating type water and heat vacuum drying device,concentrating on the explor ation of its processing art. In order to find out the effect of post-processing on ultrafineparticles agglomeration and effective methods of repressingagglomeration and gain high-pure ultrafine and well-dispersing dryingproducts, it has analyzed and explored agglomeration and dispersionmechanism of ultrafine powder. Dehydrating the fine products with organic reagent (dehydratedethanol etc)after they are filtered and washed can effectively repressthe agglomeration phenomenon of ultrafine explosive particles in dryingprocess and realize the safety of ultrafine explosivepost-processing..... How to repress agglomeration of ultrafine powder effectively is akey technique in the post-processing of producing ultrefine materialwith wet chemistry way. The achievement of this paper not only has thepractical significance for the ultrafine single material explosiveproduction technology but also lay the foundation for the applicationstudy of Nami energy material.
