The paper presents the test results of an ultrafiltration unit. During the test, one of the main parameters of the ultrafiltration process, membrane permeability and a rational process parameter, a linear velocity in the range of 4-7 s/m . According to the results, it can be determined that the process is considered effective if the membrane permeability remains maximum for a long time at a given selectivity and with minimal energy consumption. It was found that for ultrafiltration separation of concentrated solutions of iron hydroxide, the optimal values of the linear velocity are in the range of 5.0-10.0 s/m at …
Research Of Features And Compositions Of Vermiculite For Use As Suspension Fire Retardant For Textile Materials, I.N. Khaidarov, R.I. Ismailov
Research Of Features And Compositions Of Vermiculite For Use As Suspension Fire Retardant For Textile Materials, I.N. Khaidarov, R.I. Ismailov
Technical science and innovation
This article presents studies of fire resistance in the treatment of expanded vermiculite, which depends on the size of the dispersed particles and the orientation of the granules, their moisture and temperature. It has been studied that one of the interesting and important in practice properties of vermiculite is its ability to swell and turn into a lightweight effective material for imparting fire resistance. The properties and compositions of vermiculite from the Tebinbulak deposit are studied, from which a flame-retardant suspension is prepared for processing textile materials based on vermiculite dissolved in orthophosphoric acid and alkali in an aqueous medium. …
