摘要： The invention relates to a method of manufacturing a sandwich panel (10). Such a sandwich panel consists of a foamed core layer (12) and at least one thermoplastic cover layer (14). The sandwich panel is made by in situ foaming. In a first assembling step a core web, comprising at least one sheet of a thermoplastic material (12) containing an amount of a suitable physical blowing agent is positioned between two cover layers (14). The assembly of core web and cover layers is arranged between two press plates. Due to heat and pressure applied in a subsequent foaming step, foaming of the core web and effective bonding thereof to the cover layers is achieved. Subsequently the foamed assembly is allowed to cool down. Remaining physical blowing agent is removed during a subsequent drying step at elevated temperature while the outflow of physical blowing agent via the peripheral edges of the panel (10) is restricted, e.g. by taping (24) or clamping by clamps (16, 20).

摘要： The invention relates mold, particularly a mold for producing foam articles. In a preferred embodiment, the mold comprises a lid and a bowl releasingly engageable to define a mold cavity, the lid comprising: (i) a vent having a passageway for gas to escape from the mold cavity, and (ii) a plurality of grooves connected to the vent. The use of a plurality of grooves/slots in the mold cavity surface effectively acts as a siphon to draw gas away from the composition to be molded. The plurality of grooves/slots is connected to one or more vents which then allows for escape of the gas from the mold cavity to the exterior of the mold.

摘要： An industrial sponge device wherein the sponge is made from a polyvinyl acetal material with a process in which the pores are formed by gas to provide an open pore structure having no fibrils. Additionally, the sponge is purified by an extracting process which includes alternating exposure of the partially cross-linked sponge to solutions of high pH and low pH. The sponge is sterilized by electron beam radiation to destroy micro organisms that can cause contamination of the final product. The resulting sponge material is formed into an industrial sponge having a cylindrical body and a plurality of projections extending from the body. The projections are tapered truncated cones having a cross-sectional radius that decreases with distance from the body. The extracting process permits residual amounts of calcium, zinc, and other elements to be 2 ppm or less; preferably 1 ppm or less.

摘要： The method of making polystyrene foam for foam products which comprises utilizing atmospheric gases as the blowing agents or preferably mixing one or more of these gases and a blending agent which is non-volatile at the extrusion temperatures, introducing the mixture to a molten thermoplastic polystyrene resin containing nucleating agents such as sodium bicarbonate and citric acid and extruding the thermoplastic in the form of a foam. The resultant foam has substantially no residual blowing agent, is dimensionally stable at ambient temperatures and when used with a non-volatile blending agent can be made with small amounts of blowing agent permitting cooling of the melt without high loading on the extruder. The foam may be coextruded with one or more layers of thermoplastic film so that the resultant product is adapted for use for plates, cups, food containers or packaging and for labels for containers such as glass and plastic containers and for labels that are shrunk in place on a container.

摘要： A method is disclosed for accelerating the removal of blowing agent from elongate, flexible polyolefin foam bodies, such as polyethylene foam sheeting, in the absence of substantial tension on the foam body so as to avoid breaks in the foam body. The elongate flexible foam body is introduced into a heating zone and draped over a plurality of substantially parallel bars in an endless path. Tension on the foam body is avoided because the foam loops are free hanging between these parallel bars. An endless drive means transports the parallel bars through the heating zone about the endless path, thereby transporting the foam body through the heating zone for removal of blowing agent. Forced heated air is blown over the exposed surface of the foam body at a pre-determined temperature and for a pre-determined time sufficient to remove a substantial portion of the residual blowing agent and to cause sufficient air to diffuse into the foam body so that there is no substantial reduction in the thickness of the foam.

摘要： Method and apparatus for cooling porous materials whereby first gases are passed through a porous material, such as polyurethane foam, in a first zone at a predetermined flow rate to cool the porous material and to remove volatiles therefrom in a first gas mixture which exits the porous material at a predetermined temperature. The first gas mixture is combined with second gases having a temperature which is lower than that of the first gas mixture to form a second gas mixture having a temperature which is sufficiently low to condense or sublime one or more of the volatiles. Thereafter, the second gas mixture is passed through the porous material to filter the condensed or sublimed volatiles thereon and to further cool the porous material. The flow rate of the heated gases is controlled to provide a controlled uniform cooling of the porous material, and additional filters may be utilized to remove particulate matter from either of the heated gases or the cold gases, or both.
