Method for producing PET nanofoil with increased purity and PET nanofoil with increased purity

摘要

method of production of pet (polyethylene terephthalate) in the process of extruding comminuted raw material pet, is that: preparing regranulat uszlachetniony pet in this way that to the pure regranulatu pet (101) implantuje to silver nanoparticles asthat clean regranulat pet subjected alternately to coating colloidal solution containing: niepolarny relationship of alkanes, with a boiling point below 70u00b0c: from 97% to 98,9% by weight, rozpu0142ywnou015bci modifier: from 0.5% to 1% by weight, measure odpowietrzaju0105cy: from 0,5% to 1% by weight, wetting agent, from 0.1% to 1% by weight, silver nanoparticles in the coating with the family of paraffins.about the size of 3 nm to 8 nm, at a concentration of 50.000 ppm by weight; and drying the coated solution regranulatu at a temperature below 70u00b0c until a concentration of silver in regranulacie level from 100 ppm to 500 ppm by weight; and regranulat uszlachetniony pet (105) is mixed with regranulatem pure pet (101) and / or gran ulatem original pet (106) in proportions providing a concentration of silver in the mixture na level from 5 to 100 ppm by weight and with that obtained mixtures shall be moulded by ekstrudera (108) ribbon film, which is formed and talking on a bolt.
