Abstract
Sposób wytwarzania folii PET (politereftalanu etylenu) w procesie wytłaczania rozdrobnionego surowca PET, polega na tym, że: przygotowuje się regranulat uszlachetniony PET w ten sposób, że do czystego regranulatu PET (101) implantuje się nanocząstki srebra tak, że czysty regranulat PET poddaje się naprzemiennie operacjom powlekania koloidalnym roztworem zawierającym: niepolarny związek z grupy alkanów, o temperaturze wrzenia poniżej 70°C: od 97% do 98,9% wagowo, modyfikator rozpływności: od 0,5% do 1% wagowo, środek odpowietrzający: od 0,5% do 1% wagowo, środek zwilżający: od 0,1% do 1% wagowo, nanocząstki srebra w otoczce z rodziny parafin, o rozmiarze od 3 nm do 8 nm, w stężeniu 50.000 ppm wagowo; oraz suszenia powleczonego roztworem regranulatu w temperaturze poniżej 70°C aż do uzyskania stężenia nanocząstek srebra w regranulacie na poziomie od 100 ppm do 500 ppm wagowo; po czym regranulat uszlachetniony PET (105) miesza się z regranulatem czystym PET (101) i/lub granulatem pierwotnym PET (106) w proporcjach zapewniających uzyskanie stężenia nanocząstek srebra w mieszance na poziomie od 5 do 100 ppm wagowo i z tak uzyskanej mieszanki wytłacza się za pomocą ekstrudera (108) wstęgę folii, którą formuje się i nawija na belę.The method of producing PET (polyethylene terephthalate) film in the process of extruding fragmented PET raw material is that: a PET refined regranulate is prepared in such a way that silver nanoparticles are implanted into pure PET regranulate (101) so that pure PET regranulate is subjected to alternating coating operations with a colloidal solution containing: a non-polar compound from the group of alkanes, with a boiling point below 70 ° C: from 97% to 98.9% by weight, flow modifier: from 0.5% to 1% by weight, deaeration agent: from 0, 5% to 1% by weight, wetting agent: from 0.1% to 1% by weight, silver nanoparticles in a paraffin family shell, size from 3 nm to 8 nm, at a concentration of 50,000 ppm by weight; and drying the solution coated with the regranulate at a temperature below 70 ° C until obtaining a concentration of silver nanoparticles in the regranulate at a level from 100 ppm to 500 ppm by weight; then the enriched PET regranulate (105) is mixed with pure PET (101) regranulate and / or PET primary granulate (106) in proportions ensuring obtaining a concentration of silver nanoparticles in the mix at a level of 5 to 100 ppm by weight and the resulting mixture is extruded with the help of an extruder (108) a film web that is formed and wound on a bale.
