摘要： In a method of integrating an active pharmaceutical ingredient (API) with a thermoplastic polymer, the thermoplastic polymer and API are into a first feed port of a multi-screw extruder or the thermoplastic polymer is fed into the first feed port of a multi-screw extruder, the thermoplastic polymer is conveyed along the heated multi-screw extruder while heating the thermoplastic polymer to a melt temperature of 160° C.-280° C. prior to the thermoplastic polymer being conveyed past a second feed port and the API is fed into the second feeding port in the heated screw extruder to mix with the melted thermoplastic polymer to generate a compounded mixture containing 85-100% of the starting API content. The compounded mixture is extruded from an outlet of the heated screw extruder and cooled via a cooling device such that the compounded mixture contains 85-100% of the starting API content.

摘要： A barrel block for a twin-screw extruder constitutes a barrel including a cylinder and has joints at both ends. A first joint includes a first inner joint face on a peripheral edge of a first hole of an insertion hole for screws, and includes a first flank face and a first outer joint face on an outer periphery of the first inner joint face. The first outer joint face is located in the outer periphery of a plurality of first bolt holes. The first outer joint face is more recessed toward a second block end face than the first inner joint face.

摘要： A method of forming a fiber-reinforced molding compound. The method includes establishing a melt stream of a source material and dosing a composite material into the melt stream. The composite material includes carbon reinforcing fibers pre-impregnated by a polymeric material. The composite material has at least 30% of the fibers protected by the polymeric material. The method further includes forming a molding compound from the source and composite materials, dispensing the molding compound from the extruder, and using the molding compound to produce a part.

摘要： A process for continuously preparing a polyolefin composition made from or containing a polyolefin and carbon black in an extruder device. The process includes the steps of supplying polyolefin in form of a polyolefin powder and carbon black to a mixing device; alternatively, (a) measuring the flow rate of the polyolefin powder supplied to the mixing device or (b) measuring the flow rate of the polyolefin pellets prepared in the extruder device; adjusting the flow rate of the carbon black to the mixing device in response to the measured flow rate of the polyolefin powder or adjusting the flow rate of the polyolefin powder to the mixing device in response to the measured flow rate of the polyolefin pellets; melting and homogenizing the mixture within the extruder device; and pelletizing the polyolefin composition into the polyolefin pellets.

摘要： A double-screw extruder for thermoplastic materials, with a first and a second extruder screw, whereby the extruder screws have an inlet and an outlet and a core, helically extending screw flights being arranged through the core from the inlet to the outlet, so that the screw peaks and valleys are circumferential, and the peaks of the first screw penetrate into the valleys of the second screw, and vice versa. The screw flights may have a geometry which is step-shaped in cross section, whereby the steps may be provided such that the stepped course of the peaks is congruent with the stepped course of the valleys.

摘要： The present invention consists in a method and a composition for obtaining films of a thermoplastic polymer, preferably polyethylene, that are non-breathable and heavily charged with treated mineral particles in order to leave hollow spaces in the structure thereof, resulting in a significant reduction in density.Owing to the fact that said films exhibit improved stability to the stresses they undergo during processing in diaper-production machines, and because, furthermore, they offer an important saving in terms of costs owing to the high mineral-filler content thereof and the low density thereof, they are especially suited to use as an outer covering for disposable diapers and sanitary towels.
