摘要:
A method of manufacturing a floor panel with insulating properties comprises the steps of supplying a panel (1) having an upper side (2) and a back side (3), applying a curable substance (5) to the back side (3) of the panel (1) and curing the substance (5) for forming a layer (7) with insulating properties.

Method and device for the production of expanded polystyrene blocks, comprising expansion of the loose mass (7) of polystyrene spheres within a polyhedral mould (2-3), one face of which is formed by the end surface (9) of the previously produced block of polystyrene (8), bonding the newly expanded block (7-8) to this end (9)as one and the same substance, advancement of the block (8) until it becomes an end (9) for another block, and so on, thus producing a continuous block (8) which can be cut to any size without generating waste or scrap.

The invention relates to a novel, innovative industrial method for producing polystyrene (EPS) foam parts of arbitrary length and having a constant cross-section, with mixed densities located in accordance with the mechanical and thermal properties required for each application. The invention also relates to a machine (apparatus) for producing said solid parts having localized densities defined by the mechanical and thermal requirements of the application. The aforementioned products are produced by joined both longitudinally and transversely. The invention can be used to reduce the standard method to three steps, thereby resulting in a significant saving in terms of production. Moreover, unlike with the standard method, variants can be produced using the above- mentioned method, thereby increasing the range of application said type of products.

The invention relates to a method for producing winding tubes. According to this method, a regenerated PVC material is reduced to a granulate and the resulting granulate is melted, foamed and the foamed melt extruded. The invention also relates to a winding tube consisting of plastic, especially regenerated PVC material, produced according to the inventive method.
摘要:
An extrusion system utilizes single (30) or tandem extruders (102) and (103) and a mixer-cooler (104) to extrude a foamable extrudate through a die (37) in a sealable chamber. The foamable extrudate is shaped and calibrated within the chamber. The die (37) is mounted on the end of a gel tube (120) projecting through a gland seal in a fixed bulkhead (36) forming the upstream end of the chamber (40). The gel tube (120) and mixer-cooler (104) are mounted on a movable carriage, movement of which may be used to adjust the die (37) with respect to the shaping and calibrating equipment inside the chamber. The mixer-cooler (104) achieves a selected narrow range of uniform viscosity of the melt at the die (37) depending on the size of the product and density. The mixer-cooler (104) enables a large size low density product to be produced with uniform cellular structure without collapse or density gradients, as the product is subjected to pressure and temperature transformations passing from the chamber to atmosphere through the water.
