Method for producing heat-insulating elements from expanded polystyrene and the heat-insulating elements from expanded polystyrene

摘要

the object of the application is the way the manufacture of application of thermal blankets foam polystyrene, in which the raw material in the form of granules of polystyrene is subjected to preheating temperature from 35 to 55u00b0c in time from 30 to 90 seconds, with pre heated process it takes place in u015blimakowym dispenser using heat energy recovered in the process of the foam.then the pre heated raw material is then foamed foam process, the raw material is subjected to the ageing process in constant temperature from 30 to 120 degrees in the time from 4 to 8 hours, with the process of ageing is carried out using the heat energy recovered in the process ie formation in block, then the raw material is subjected to wysezonowany process moulding in blockthe raw material is added from 1 to 3% by weight ekspandowanego glass granules size grains from 0.04 to 0.125 mm, and in the final stage of forming in the block of material is subjected to the action of the vacuum, air, and then pressure air or inert gas in the range from 0 3 to 0,6 bar at a time from 30 to 90 seconds,and then a raw material is subjected to ageing process block in temperature from 10 to 105 in a time from 36 to 60 hours, preferably 48. termoizolacyjny element of foamed polystyrene, in which the level of the deviation density in unit weight is + / - 0.1 0.1 kg / m3, containing from 1 to 3% by weight ekspandowanego glass granules size grains from 0.04 to 0.125 mm.
