摘要： A method for the production of articles moulded in polyurethane, in particular in compact and semi-compact polyurethane.
According to the invention, the polyurethane mixture is compressed directly in the mould cavity (13) from a moment (Tx) chosen in the time interval between the end of the feeding phase of the mixture into the mould (11) and the instant in which a filament may be formed in the polymerization process of the polyurethane material (24), during which the polyurethane material (24) is in a transitional condition between liquid and solid states.
In the above way, moulded articles with well-defined markings and free from defects due to eventual surface air-bubbles are obtained.

摘要： A mixing apparatus for reactant plastic materials, comprising a low-pressure mixing head (10) having a mixing chamber (12) for mixing metered quantities of reactive chemical components (A, B) supplied via separate feeding ducts (18, 20) to one end of the chamber (12) opposite to an outlet opening (13), and an impeller (14) in said chamber (12) connected to a drive motor (16). Pressurized air cleaning means (21, 22, 23) are provided for cleaning the chamber (12) and the rotor (14); said cleaning means comprises a booster (23) and air inlet (21) opening into the mixing chamber (12) for generating a super pressure air flow impinging the inner walls (11) and the impeller (14) of the mixing chamber (12), and to remove the mixture adhered to the impeller and the mixing head.
