The high-impregnation-degree long glass fiber reinforced polypropylene composite material disclosed by the invention has the following technical effects that each glass fiber is wrapped by the polypropylene resin, so that the glass fibers are prevented from being damaged in a pellet plasticizing process, the length of the glass fibers in a product is reserved, and the tensile strength, flexural modulus, impact strength and other properties are greatly improved.

Process arrangement method for mixed jet cleaning
The invention relates to a process arrangement method for mixed jet cleaning. The method employs high-pressure mixed jet descaling units having a plurality of abrasive materials with different granularities. The high-pressure mixed jet descaling units are arranged along a tape transport direction of a metal plate. The high-pressure mixed jet with large granularity abrasive materials is arranged at an original inlet area of the metal plate, with the granularity of 20 meshes-60 meshes and inject pressure of 15 MPa-80 MPa; the high-pressure mixed jet with medium granularity abrasive materials is arranged at downstream of the high-pressure mixed jet descaling unit with the large granularity abrasive materials, with the granularity of 40 meshes-80 meshes and inject pressure of 10 MPa-60 MPa; the high-pressure mixed jet descaling unit with small granularity abrasive materials is arranged at downstream of the high-pressure mixed jet descaling unit with the medium granularity abrasive materials, with the granularity of 60 meshes-120 meshes and inject pressure of 10 MPa-50 MPa; the metal plate realizes the front and back descaling of the metal plate via the above jet descaling units; and the washing of the metal plate is finished by passing the descaled metal plate through a high-pressure pure water cleaning unit, a wiping unit and a compressed air blowing unit. The complete removing treatment of the scales on two sides of the coal metal plate is realized via a jet way.
