Die Größe der Körner beträgt 1 bis 5 mm. Dieses Material gelangt in eine Mischanlage, Sägespäne werden dazugegeben (Korngröße 1 bis 5 mm), ferner Glasfasern. Das Gemisch wird durch Rühren homogenisiert, der Klebestoff auf der Basis von Harnstoffformaldehyd-Harz mitsamt dem Härtemittel und Wasser, Hemmstoffe (brand- und bakterientätigkeitshemmende Zutaten) werden ebenfalls dazugegeben. Diese Mischung wird solange gerührt, bis sie vollständig homogen ist, dann werden allmählich damit Formen gefüllt, in denen unter Druck- und Wärmeeinwirkung, das Material gehärtet wird.The heat and sound insulating material from the foam waste produced in the form of sheets, especially for façades, for outdoor and indoor use, using this example as an example, is produced as follows: Broken and waste polystyrene is grated into small grains. The size of the grains is 1 to 5 mm. This material enters a mixing plant, sawdust is added (grain size 1 to 5 mm), and glass fibers. The mixture is homogenized by stirring, the adhesive based on urea formaldehyde resin together with the hardening agent and water, inhibitors (ingredients that inhibit fire and bacteria activity) are also added. This mixture is stirred until it is completely homogeneous, then molds are gradually filled with it, in which the material is hardened under the action of pressure and heat.
