process for the production of large plastic tanks, is that a cylindrical pipe separately and bottom tank, which then welds together.cylindrical pipe is produced by spiral winding in rotary - drum sliding external diameter equal to the internal diameter of the cylindrical tube, the ribbon of extruded polyethylene layer with enriched granules forming inner tubes, which subsequently going on to the ribbon wytu0142aczaju0105 pure polyethylene granules forming layer structural tubeshow to design a korugowanu0105 pipe layer of polypropylene, which spiral tracks to the ribbon wytu0142aczaju0105 pure polyethylene granules forming the external layer.granules enriched prepared in such a way that the raw granular polyethylene glycol implantuje to silver nanoparticles in this way that raw granules glycol are alternately to colloidal solution containing alcohol niskorzu0119dowy coating granules of t emperaturze boiling from 65 to 85u00b0c: from 95.5% to 99.1% by weight,surfactant lowers surface tension: from 0.2% to 2.0% by weight; measure adhezyjny: from 0.5% to 1.0% by weight; dispersant: 0.1% to 1.0% by weight; a viscosity modifier: 0.1% to 0.5% by weight of silver nanoparticles in the coating; polymer size from 40 nm to 60 nm, in st. u0119u017ceniu 10.000 ppm by weight; and drying the coated solution of granules at a temperature below 85u00b0c until a concentration of silver in granulacie level from 100 ppm to 200 ppm by weight.
