摘要： A method for obtaining and applying a sealing gasket element (1) on a slide-valve (2) sliding in a cavity (3) of an apparatus (M) for the recirculation and mixing of chemically reactive polymeric components, comprises the steps of: obtaining from an elastic-plastic material a precursor element (P) of the seal element (1), with a grid structure having a reticular shape; positioning the precursor element (P) around the slide-valve (2); exerting on the precursor element (P), through temporary clamping elements (C1, C2, C3; C4), a radial compression and contraction action to insert it and couple it to one or more housing seats (S) provided on the slide-valve (2) so as to obtain the seal element (1) well coupled to the latter; progressively removing the clamping elements (C1 ,C2, C3; C4) to sequentially release successive parts of the gasket element (1) and gradually free the slide-valve (2) to gradually introduce the parts of the slide-valve (2) - freed in succession - in the housing cavity (3) allowing the sealing gasket element (1) to gradually expand radially due to the elastic return by adhering tightly to the inner surface of the same housing cavity (3). The special equipment for fitting the sealing gasket element (1) on the slide-valve (2) and the so obtained recirculation and mixing apparatus (M) is also described.

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).

The self-lubricating and scraping device comprises a delivery chamber (22) for the lubricant material axially aligned and in fluid communication with the outlet duct (13); the lubricant delivery chamber (22) is connected to a storage tank (23) by a feeding and re-circulation circuit (24A,24B).
The lubricant is sucked into the outlet duct (13) and subsequently returned into the delivery chamber (22) by a cleaning member in the form of a pumping piston (18) sliding into the outlet duct (13), the pumping piston (18) being provided with scraping rings for removing the reacted mixture adhered to the inner surface of the outlet duct (13).
