AUTOMATED TECHNOLOGICAL LINE FOR SURFACE MODIFICATION OF POLYMER FIBROUS MATERIAL BY METAL OXIDE NANOPARTICLES Russian patent published in 2015 - IPC B01D39/16 B82B1/00 

FIELD: chemistry.

SUBSTANCE: automated technological line for surface modification of polymer fibrous material by metal oxide nanoparticles can be applied in production of filtering material, intended for purification of water from organic pollutions. Composition of automated line includes successively placed hydrolysis unit, container-accumulator of polymer fibrous material, SHF unit, unit of ultrasonic washing and unit for drying modified polymer fibrous material. Travel of polymer fibrous material is carried out by means of tape drive mechanism. Tape drive mechanism consists of pinch rollers, placed on input and output of all units, and guide rollers, placed inside each unit. Container-accumulator is intended for synchronisation of travel speed of polymer fibrous material from reservoir with metal salt solution of hydrolysis unit into SHF unit. Magnetrons in SHF unit are placed parallel to the line of polymer fibrous material travel and are installed with possibility of ensuring alteration in half-wave of maximums and minimums of electromagnetic field. Quarter-wave absorbing traps are placed on input and output of SHF unit. Unit of ultrasonic washing includes reservoir from stainless steel for washing liquid and electronic ultrasonic generator, connected with integrated into reservoir body ultrasonic transformer. Unit for drying of modified polymer fibrous material is made in form of hermetic container, inside of which infra-red lamps are placed in rows, and is equipped with exhaust fan. Work of automated technological line is realised from unit of automated control.

EFFECT: invention makes it possible to provide coordination of work of all units, continuity of process of obtaining filtering material and ensure uniform distribution of metal oxide nanopartilces on the surface of polymer fibrous material.
