A method for manufacturing of polyethylene regranulate and extruded elements from polyethynele regranulate

摘要

A method for manufacturing of polyethylene regranulate, characterized in that to a raw polyethylene regranulate silver nanoparticles are implanted in such a way that the raw regranulate is subject to alternate steps of coating the regranulate with a colloidal solution comprising: a hydrocarbon with a boiling point below 70°C: from 98% to 99.6% by weight, a surfactant reducing surface tension: from 0.1% to 0.5% by weight; an adhesive agent: from 0.1% to 0.5% by weight; a dispersant: from 0.1% to 0.5% by weight; a viscosity modifier: from 0.1% do 0,5% by weight; silver nanoparticles in a paraffin shell having a size from 3 nm to 8 nm and in concentration of 50,000 ppm, and drying the coated regranulate at a temperature below 70°C, until the silver nanoparticles in the regranulate reaches the concentration of 500 ppm to 1000 ppm by weight.
