摘要： An extruder according to the invention comprises at least two annular conical feed gaps (9) one within the other, formed between a rotatable rotor (1) and a stator (4, 5). At least some of the material to be extruded is subjected in the different feed gaps (9) of the extruder alternately to a higher pressure and then to a lower pressure. The rotor (1) or stator (4, 5) between the feed gaps (9) can then be balanced such that the pressure effect provides a hydrodynamic bearing, whereby, when the extruder is used, even at worst a very small force is exerted on die other bearings of the rotor (1) or stator (4, 5). By the method of the invention, a product can also be produced which contains cross-linked and at least partly oriented polyethylene.

摘要： A method for the manufacture of a cross-linked extruded elongated product from polyethylene or other suitable polymer. The polymer is fed into the hopper of a screw extrusion machine. The polymer is heated and melted while being conveyed through the barrel of the screw extruder. A liquid silane compound which comprises a modified vinyl functional silane, a free-radical generator, and a condensation catalyst is carefully metered and injected into the melted polymer. The melted polymer and the liquid silane compound are then mixed and blended to obtain a uniform blended mixture thereof. The blended mixture is then extruded through an extrusion die to form an elongated product of a required final shape and the elongated product is then subjected to the action of moisture and heat until the polymer in the elongated product is cross-linked.

摘要： The invention relates to a method and apparatus for using recycled plastic material, and to a plastic product produced by an extruder. In the invention, crosslinked polyethylene is ground to powder form and mixed with e.g. polyethylene so that the proportion of the crosslinked polyethylene in the mixture is less than 30%. The mixture is supplied through an extruder (2) for making an extruded plastic product. In this way, crosslinked polyethylene can be recycled in a cost-effective and simple manner, while producing a plastic product that contains recycled crosslinked polyethylene.

摘要： A screw apparatus comprises a melting extruder for melting a resin; a screw unit for kneading molten resin and reinforcing fibers to obtain a reinforcing fiber-containing molten resin and supplying it; and a mixer in which at least a part of the reinforcing fibers attach to the molten resin which is extruded from the melting extruder and flows down owing to gravity in an open space, and then the reinforcing fibers and the molten resin are fed into the screw unit.
