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

Abstract: A high-pressure mixing apparatus for polymeric components suitable for providing a reactive mixture for a polymerizable resin, provided with a self-regenerating seal. An annular sealing element is housed in a circular seat inside a cross hole of a bush transversely extending to and in communication with the mixing chamber, in a sealing zone downstream the injection holes for the polymeric components, between the mixing chamber and the same delivery bush; worn and/or torn parts of the annular sealing element are automatically regenerated by the reactive mixture delivered during operation of the mixing apparatus.

Abstract: A method for forming a self-regenerating seal in a mixing chamber of a high-pressure mixing apparatus for polymeric components suitable for providing a reactive mixture for a polymerisable resin. An annular sealing element is provided in a circular housing seat inside the mixing chamber, in a sealing zone downstream the injection holes for the polymeric components; worn and/or torn parts of the annular sealing element are automatically regenerated by the same reactive mixture delivered during operation of the mixing apparatus. A high-pressure mixing apparatus with self-regenerating sealing element is also claimed.
Abstract translation: 一种用于在适用于提供可聚合树脂的反应混合物的聚合物组分的高压混合装置的混合室中形成自再生密封件的方法。 环形密封元件设置在混合室内的圆形壳体座中，在用于聚合物组分的注入孔下游的密封区域中; 环形密封元件的磨损和/或撕裂部分由混合装置操作期间输送的相同反应混合物自动再生。 还要求具有自再生密封元件的高压混合设备。
