A dry granulation process using a twin-screw extruder for granulating a powder mixture which includes at least one active ingredient and at least one carrier. The process includes steps of kneading the powder mixture in the screw barrel of the twin-screw extruder at a barrel temperature below a melting point of the at least one active ingredient and a melting point or a glass transition temperature of the at least one carrier to provide a kneaded powder mixture, and extruding the kneaded powder mixture to form granules. Granules and tablets produced using the dry granulation process in the twin-screw extruder are also provided.

A method of manufacturing a fiber-reinforced resin material, includes preparing a kneaded material by melting a thermoplastic resin and kneading the molten thermoplastic resin with reinforcing fibers; preparing a reinforcing fiber-impregnated material including a supercritical fluid by accommodating the kneaded material in a sealed space and supplying the supercritical fluid into the sealed space such that the molten thermoplastic resin is impregnated into the reinforcing fibers included in the kneaded material; and manufacturing the fiber-reinforced resin material by extracting the reinforcing fiber-impregnated material from the sealed space and leaving the reinforcing fiber-impregnated material to stand in a reduced-pressure atmosphere such that the supercritical fluid foams.

A thermoplastic starch (TPS)/polylactic acid (PLA)/poly(butylene adipate-co -terephthalate) (PBAT) blend modified biodegradable resin is prepared by using a chain extender, and is prepared from the following raw materials: 20-30 parts by weight of TPS; 20-30 parts by weight of PLA; 40-60 parts by weight of PBAT; and 0.5-0.9 parts by weight of a chain extender KL-E. The preparation method is a two-step method: blending the TPS with the PBAT in a twin screw for granulating; mixing TPS/PBAT mixed granules with PLA granules, and dissolving the chain extender KL-E into an ethyl acetate solution. The chain extender KL-E can be uniformly distributed in PLA and TPS/PBAT mixed granules by using a spraying method, and the remaining short-chain molecules and terminal carboxyl molecules in the mixed granules can be changed into long-chain molecules.

A fiber-reinforced polyimide resin molded article and a production process therefor. After a prepolymer of an addition reaction type polyimide resin and functional fibers are dispersed and kneaded together, the kneaded product is kept at a temperature not lower than the heat curing start temperature of the reaction type polyimide resin for a fixed amount of time or mixed with a thickener to increase its viscosity, and shaped at a temperature not lower than the heat curing start temperature of the reaction type polyimide resin to obtain a molded article having excellent sliding performance with a limit PV value of not less than 3,000 kPa.Math.m/s and excellent shape stability during molding and containing the functional fibers dispersed in the polyimide resin.

Disclosed is a filter housing which is a molded body of a fluororesin composition in which carbon nanotubes are dispersed in a fluororesin, wherein the fluororesin composition comprises 0.01 to 2.0% by mass of the carbon nanotubes.

The present disclosure discloses a meshing-type rubber internal mixer and a working method thereof. The meshing rubber internal mixer includes a frame mechanism, a mixing mechanism, and an unloading mechanism. The mixing mechanism is on the upper side of the unloading mechanism. The mixing mechanism and the unloading mechanism are in the frame mechanism. An internal mixing chamber is of a closed structure through first automatic telescopic plates and second automatic telescopic plates. The gap between a first meshing-type rotor and a second meshing-type rotor is small, a material is compressed to enter the space between the first meshing-type rotor and the second meshing-type rotor to be extruded with an internal mixing chamber wall. The material is flaky in the internal mixing chamber, so that the material produces great strain deformation, thereby achieving excellent dispersing and mixing effects.
