Аннотация

Subjects of research: a fibre Nitron waste, highly hydrolyzed poly electrolyte, glycerine, gossypol pitches, the salted sand, flocculant RS-2-3, structure forming agent MS-1. The work purpose: Development of technology of reception of new kinds of highly hydrolyzed poly electrolytes on the basis of a fibre Nitron waste, modified by three-nuclear alcohol - glycerine and an oil fat industry waste the gossypol pitch, studying of their colloid-chemical properties and research of possibilities of areas of practical application. Research methods: colloid-chemical, physical and chemical, IR-spectroscopy, microscopic and other methods of the analysis. The results obtained and their novelty: for the first time the new technology of reception of VGPA on the basis of OPVN with high degree of hydrolysis in severe constraints and also its modified derivatives is developed: glycerine - a reagent of PS-2-3 condensation and gossypol pitch - thermal salt-resisting modified structure forming agent MS-1; it is established, that the polymers obtained do possess flocculating and structure forming properties and can be applied as regulators of colloid-chemical properties of industrial disperse systems. The practical importance: the way of a condensation of concentrates of precious metals using structure forming structure forming flocculant PS-2-3 and a method of chemical fastening of the salted sand using structure forming agent MS-1 is developed. Degree of embed and economic effectivity: Reagent PS-2-3 has passed trial and industrial tests in quality of flocculant for a condensation of foamy floating concentrates containing precious metals, on Angrensky GEF of Open Society «Almalyk GMK» and is introduced in manufacture with economic benefit of 300 million soums a year. Complex use of MS-1 together with wood sawdust has provided prevention of erosion of sand and improvement of ecological conditions at the drained bottom of Aral sea. Fastening of the salted sand with complex additive MS-1 with the wood sawdust there has passed skilled-field tests with positive results at coast of Kazahdarya of drained bottom of Aral sea and is recommended for introduction. Field of application: the condensation of concentrates of precious metals at mountain-metallurgical industry as well as fastening of the salted sands at the drained bottom of Aral sea and its region.
