SOLUTION: This is a kneading rotor 4 comprised of a first long blade 13 and a second long blade 14 which are formed longer than a half of a rotor length W and a first short blade 15 and a second short blade 16 which are formed shorter than a half of the rotor length W. The first short blade 15 is a linear blade arranged behind the first long blade 13 in a rotation direction of the rotor. The second short blade 16 is a linear blade arranged behind the second long blade 14 in a rotation direction of the rotor. The first long blade 13 has a kneading blade top part formed so that three stage of different tip clearances which are combined by a large tip clearance, a medium tip clearance and a small tip clearance are serially generated along the blade in a longitudinal direction. The blades except the first long blade 13 has the blade top part formed so that the tip clearances are less than the large tip clearance and more than the small tip clearance.

摘要： PURPOSE:To make the uniform mixing of highly viscous materials such as plastics, rubbers or the like possible by a structure wherein ridge lines or wall portions of cavities on a stator side and on a rotor side are made parallel to the shifting directions of a rotor and of a stator. CONSTITUTION:Groups 27 and 28 of cavities are produced by disposing trains 25 and 26 of cavities, which are formed by disposing cavities 23 and 24 in an array running in the circumferential direction (X X), in an array running in the direction (Y Y) of the axis center line on the inner peripheral surface of a stator 21 and on the outer peripheral surface of a rotor 22 excluding both the end parts of the rotor 22. Each cavity 23 or 24 is a parallelogram in the developed state with one pair of opposite wall portions 29 and 30, which run normal to the direction (Y Y) of the axis center line and have a space interval in the direction of the axis center line, and the outer pair of opposite wall portions 31 and 32, which respectively connect with the wall portions 29 and 30 and run obliquely in the same direction as each other to the direction (Y Y) and have a space interval in the circumferential direction (X X). Due to the constitution as described above, material pressed in the stator 21 is shifted from each cavity 23 or 24 to the cavity 24 or 23 overlapped to each other by means of the pressing-in force of extrusion members so as to be forcibly advanced in the extrusion direction Z. In addition, no force acting in the counter extrusion direction develops and no material is left in the cavities.

摘要： PURPOSE:To provide a fire retardand for molding sand for Mg alloy casting which comprises containing PE powder of a prescribed grain size range as an effective component, and which is extremely high in burning preventing effect and can prevent blowhole defects. CONSTITUTION:PE powder of 100-270 meshes is compounded as a fire retardant in the 2-10% range with molding sand for Mg alloy casting. When, for example, a phenolic self-hardening mold is manufactured by using this molding said, its burning preventing effect is extremely high as compared to the usual fire retardant. Since said fire retardant is powdery and granular and has no possibility of reacting with sodium silicate, it is compounded at a sufficient amount with a CO2 type mold, whereby high burning-preventing effect is obtained. Further, when said fire retardant is adapted to a self-hardening mold, PE is first decomposed by the heat of molten metal and forms a protecting film on the surface of molten Mg; therefore, blowhole defects are prevented.

摘要： PURPOSE:To recover a high-purity monomer with a slight discoloration economically in high yield, by continuous thermal decomposition of a waste polymethyl methacrylate resin in the presence of a specific additive, using an external heating rotary kiln. CONSTITUTION:A waste polymethyl methacrylate resin is fed from the feed unit 1 through the hopper 3 together with an additive, which is fed from the feed unit 2, to the external heating rotary kiln 5 which is slanted at a specific angle. The additive is an inorganic material or metal powder, e.g. alumina, Al powder, sand, etc., and the weight ratio of the additive to the corresponding resin is >=4:1. The materials are thermally decomposed by the kiln 5 rotating at a constant speed. The monomer formed is fed through the tube 17, condensed in the cooling tower 11, and stored in the tank 12. A non-condensable gas is circulated through the tube 16 and the kiln 5. The additive is recovered from the bottom of the hood 8 to remove carbides, and then returned to the feed unit 2 via the tube 15.
