Method for producing blow molding grade PET and the blow molding grade PET

摘要

process for the production of regranulatu pet (polyethylene terephthalate), is that the raw material waste is subjected to preliminary washing, sorting out coordinated, they had to form flakes, after which odseparowuje flakes to metallic residues.is then flakes washing hot and washed and cleaned and processed into the extrusion machine to form threads, which is subjected to cooling and cutting with clean regranulat pet.carried out in closed-loop bath washing pre washing hot and cooling the aqueous colloidal solution nanosrebra to obtain concentration of silver in the bath at a level at least 5 ppm by weight, and to clean regranulatu pet implantuje to nanoczu0105s in the silver in this waythat clean regranulat pet subjected alternately to coating colloidal solution containing: - niepolarny relationship of alkanes, preferably hexane, with a boiling point below 70u00b0c: from 97% to 98,9% by weight - rozpu0142ywnou015bci modifier, preferably triton: from 0.5% to 1% by weight this measure odpowietrzaju0105cy, favourably bull and 555: from 0.5% to 1% by weight; wetting agentadvantageously the bull a909: 0.1% to 1% by weight of silver nanoparticles in the coating; - family paraffins, size from 3nm to 8nm, concentration of 50000 ppm by weight; and drying the coated solution regranulatu pet at a temperature below 70u00b0c, until a concentration of silver in regranulacie pet at 500 to 1000 ppm by weight, receiving regranulat enriched.
