Method for producing elements from expanded polystyrene

摘要

process for the production of components with foamed polystyrene is that raw material, which are expandable polystyrene grains undergo initial expansion in ekspanderze.then sezonuje in silo, after which drives out raw material from the silo into the positions of the moulding elements, followed by the expansion of raw material further until it shall adopt in weight caused by the form of the shape position forming elements.the raw material is prepared in such a way that the part expanding polystyrene grains acting from 10% to 50% by weight of raw material implantuje to silver nanoparticles asthe grain is subjected to the successive operations of coating polystyrene colloidal solution of silver size from 40 nm to 60 nm in isopropyl alcohol at a concentration of 1000 ppm, and drying at a temperature below 70u00b0c until a concentration of silver on the sides of pol istyrenowych at least 40 ppm.in turn, mixed with modified polystyrene grains with niezmodyfikowanym primary raw material in proportions from 1: 1 to 1: 10, preparing the mixture of polystyrene containing silver nanoparticles at a level at least 20 ppm.
