摘要： A process and a high-pressure mixing apparatus for the production of a frothed polyurethane foam. Two reactive chemical components and a low-boiling blowing agent (CO2) are mixed into a high pressure mixing apparatus comprising a mixing chamber (10) connected to a discharge duct (19); the flow of the mixture is throttled to generate a pressure inside the mixing chamber (10) which is sufficient to maintain the blowing agent at a liquid state. The mixture is thereupon frothed by releasing the blowing agent along a frothing chamber (18) extending between the mixing chamber (10) and the discharge duct (19); a back-pressure is generated into the frothing mixture by extending the frothing chamber (18) for a substantial length and by changing the flow direction of the frothing mixture while flowing from the frothing chamber (18) into the discharge duct (19).

摘要： A method and an installation for producing moulded articles of foamed plastic material having stiffening portions or stiffeners preformed by spraying onto the internal surfaces of the mould which are subsequently embedded into the body of the moulded article. According to the invention, the stiffeners (15, 17) are preformed in the same mould (1) for the article to be moulded, by spraying a quick-reacting mixture of a first plastic material having definite physical and/or mechanical properties, which adheres in pre-established positions to the internal surface of the mould (1). Then a foamable mixture (16) of a second plastic material having physical and/or mechanical properties different to those of the first material, is fed into the cavity of the mould (1), embedding the preformed stiffeners (15, 17).

摘要： A high-pressure mixing head for at least two fluid components to be mixed together. The mixing head comprises a movable mixing chamber, defined by a cylindrical hole whose longitudinal axis is parallel to the axis of an outlet duct; the mixing chamber is provided in a slider movable in a guide channel at right angles to and crossing the outlet duct for the mixture. The slider is movable from a first operative position in which the chamber is disposed on one side of the outlet duct, in correspondence with the nozzles for injecting the components to be mixed, and in which the outlet aperture of the mixing chamber communicates with the outlet duct, to a second position in which the injectors communicate with component recycling ducts, and in which the mixing chamber is axially aligned with the outlet duct and with a sliding cleaning member.

摘要： The invention concerns an apparatus (1) for the dispersion of an expansion gas even in supercritical conditions, e.g. carbon dioxide, in a reactive resin, of the kind in which a reaction chamber having an input (27) for gas and an input (37) for resin is provided. Advantageously, the chamber is a dispersion and containment chamber made into a casing (2) of predetermined high resistance susceptible to sustain high pressure and is divided into two sections (6,7) by a head (14) of a dispersion and mixing cylinder-piston group (4) in fluid communication between themselves by means of at least one pouring passage (31, 36, 32, 39) provided with a static mixer (38), motor means (3) being provided for piston (34) control of said mixing cylinder-piston group (4). The invention also concerns a process for the formation of a polyurethane foam starting with the dispersion of carbon dioxide, even supercritical, in a reactive resin in which at least one initial dispersion and mixing controlled phase of the two components is provided in a dispersion and containment chamber under pressure divided into two sections (6,7) by a head (14) of a cylinder-piston mixing group (4) in fluid communication between themselves by means of at least one pouring passage (31, 36, 32, 39) provided with a static mixer (38) and in which adduction, dispersion and mixing occurs under high pressure (at least greater than 75 bar).
