    摘要： An apparatus for continuous degassing of a chemical component (2) intended for forming a reactive resin for producing, in particular, wind blades, comprises a degassing column (3) having a bounding wall (4) that defines a degassing volume (V), traversable by the chemical component (2), in which a certain degree of vacuum is created. In the degassing volume (V) a series of lamina elements (5) is stacked that is arranged for receiving the chemical component (2) on respective receiving surfaces (SA, SB) to distribute the chemical component (2) by forming thin coats thereof that promote the release of gas by the chemical component (2). The lamina elements (SA, SB) comprise pairs of opposite tapered elements (5A,5B) that are obtained from sheet metal shaped plastically by rolling and are shaped to advance by gravity the chemical component (2) according to a path (P) with alternating corners that extends from top to bottom. Level sensor means is provided for controlling respectively: an accumulating level (L1) of the chemical component on the bottom of the column (3) (to regulate the removal flowrate from the bottom); an accumulating level (L2) on the container (11) for entry to the stack of tapered plates (5A, 5B) (for adjusting the entry flowrate to the column (3)); a safety accumulating level (L3) of the quantity of chemical component (2) that accumulates in the inlet container (11). The bounding wall (4) is transparent to permit visual control from the exterior of the advancement and accumulation status of the chemical component (2).

    摘要： A method is disclosed for foaming objects (2) inside moulding units (4) that are conveyed along an advancement path (P) by means of distinct and separate conveying modules (M T1 , M T2 ) that define a first portion (T1) and a second portion (T2) of path (P). In the first portion (T1) the steps occur of advancing moulding units (4) in an open position, extracting already moulded objects (2), preparing moulding units (4) for the subsequent foaming cycles of further objects (2), dispensing of the reactive mixture. Along the second portion (T2) of path (P) the moulding units (4) are advanced in the closed position while a polymerisation and shape-stabilisation process of said foamed objects (2) occurs. The mixture dispensing step is followed by a closing and transferring step, in which each moulding unit (4) is closed whilst, simultaneously, it is transferred from the first portion (T1) to the second portion (T2) of path (P) by a transfer-closing carousel unit (U CT ). At the end of the polymerisation and shape-stabilisation process that occurs in the second portion (T2) of path, an opening and transfer step is provided, in which each moulding unit (4) is opened whilst, simultaneously, it is transferred from the second portion (T2) to the first portion (T1) of path by an opening-transfer carousel unit (U AT ). The corresponding apparatus for implementing this method is also disclosed.

    摘要： A frothing device for delivering pre-expanded polyurethane mixtures. The device comprises a tubular gate bar (16) for distributing the mixture, provided with a longitudinal slot (18) which extends transversely and in the direction of the flow, towards a diffuser (19) comprising a pre-expansion cavity for the mixture, defined by a series of differently oriented walls (20 - 25) to cause at least one flow deviation of the polyurethane mixture emerging from the slot (18) of the distribution bar (16). The slot (18) of the distribution bar (16) has moreover slanted edges (28, 29 - fig. 3) which diverge in the flow direction and towards the pre-expansion cavity of the diffuser (19).

    摘要： A method for foaming a hollow body (2), such as a refrigerator cabinet (2), closed in a containment mold (3), that envisages the injection of a highly reactive chemical mixture (M) into the cavity (4) of the body (2), pre heated, letting it expand under vacuum conditions. The lower wall of the hollow body (2) is thermostated by a supporting table (6), in which a thermostating heat transfer fluid flows both during the insertion and stay in said containment mold (3). In particular, the surface of the lower wall of the hollow body (2), on which the resin is deposited, is heated to promote the fast and efficient expansion of the foam. The side containment and counteraction walls of the mold (3) also have a thermal conditioning function, just like the male element (48) and they carry out a heat control action on the hollow body (2); in addition, the vacuum conditions required for foaming are obtained by means of suitable gaskets.
    A first dosed quantity of mixture M is injected with a coherent jet J having an initial value of mass flow rate (mi) and average kinetic energy (E cin,sp ) of the jet (J) that forms a mixture puddle (Z1) in an intermediate area (7) of said foaming cavity (4); the coherent jet (J), by means of its thrust, causes a forward flow and a distribution of the mixture puddle (Z1, Z1') until it reaches at least 50% of said length dimension (D L ). The filling of the cavity (4) is completed by varying the mass flow rate (ṁi) and the average kinetic energy (E cin,sp ) of the coherent jet (J), keeping the body (2) thermostated and in a condition of depression until the end of the isometric expansion and polymerization of the mixture (M).
