It has been shown that introduction of aerosil additives do not essentially influence on viscous properties on PP/CPA mixture melts in spite of solid state of aerosil. The spinnability of PP/CPA/aerosil miture melts increases. The sharp improving of PP fiber-formation in CPA matrix at presence aerosil additives has place: the diameters of microfibers decrease to 0. 30 ? 0.15?m, the uniformity of distribution of microfibers on their diameters increase. The obtained results show that introduction of aerosil additives leads to essential increasing of the lifetime of PP liquid cylinder (stream) and to lowering of the interfacial tension. Aerosil additives make possible of obtaining of PP microfibers with increased in three-four times specific surface. Nanofilled filtering materials have been developed on the basis of microfibers. The technological parameters of obtaining the filter materials on the basis of nanofillered PP microfibers have been recommended. Product Description popup.authors popup.nrat_date 2020-04-02 Close
