Provided is a kneading rotor, a batch kneader and a method of kneading materials capable of obtaining kneaded materials with higher quality in comparison to conventional kneaded materials when the materials to be kneaded are kneaded in a high temperature state. The kneading rotor comprises a rotor portion which is disposed in a kneading chamber of a chamber of a batch kneader, and applies shear force, by using a plurality of kneading blades, to materials to be kneaded which pass through a tip clearance. A first long blade of the plurality of kneading blades has an apex for forming, with the inner surface of the chamber forming the kneading chamber, three-staged tip clearances of different sizes configured from a combination of a large tip clearance, a mid tip clearance that is smaller than the large tip clearance, and a small tip clearance that is smaller than the mid tip clearance so as to be arranged in the longitudinal direction of the first long blade. Each of a second long blade, a first short blade and a second short blade of the plurality of kneading blades has an apex for forming, with the inner surface of the chamber forming the kneading chamber, a tip clearance of a size that is larger than or equal to the small tip clearance and smaller than or equal to the large tip clearance.

Kneading rotor, batch kneader and method of kneading materials

A kneading rotor, in which the length Lof a long blade in the direction of rotation of a rotor section is greater than one half of the total length Lof a rotor section main body in the direction of rotation, and the long blades are arranged in such a manner that, in a case where a pair of the rotor sections are arranged mutually in parallel inside the chamber of the closed kneading machine and are rotated in mutually opposite directions, an end section on the rearward side in the direction of rotation of the rotor section, of the long blade of one of the rotor sections, and an end section on the forward side in the direction of rotation of the rotor section, of the long blade of the other one of the rotor sections, alternately repeat mutually an approaching action and a separating action, and in the state of approach, the end section on the forward side and the end section on the rearward side oppose each other in the direction of rotation of the rotor sections on a line which links the respective central axes of the pair of rotor sections, in one cross-section perpendicular to the axial direction of the rotor section.

The present invention relates to a photocurable resin composition which contains a photocurable component and forms on a substrate a photocurable resin layer having a viscosity of 1000-500,000 Pa&#xb7;s at 23&#xb0; C. and 65% RH. This resin composition is formed into a photocurable resin layer, which is laminated onto a metal sheet to give a metal sheet with a photocurable resin layer laminated thereon. This metal sheet can be worked and converted into a metal part with a high-hardness protective coating laminated thereon upon irradiation with light or electron beams after working.

PHOTOSETTING RESIN COMPOSITION, METAL LAMINATES HAVING LAYERS MADE FROM THE COMPOSITION, METAL MEMBERS MADE FROM THE LAMINATES AND HAVING HIGH-HARDNESS PROTECTING LAYERS AND PROCESS FOR PRODUCTION THEREOF

A welding wire of the type consists of a plated or uncovered solid wire and a flux-cored wire for carbon steel or stainless steel, wherein one or more of hydrocarbon compounds selected from the group consisting of saturated or unsaturated hydrocarbon compounds, which have from 5 to 12 carbon atoms and a linear or branched structure, and hydrocarbon compounds having a cyclic structure are deposited on a wire surface. A lubricating oil and/or lubricating particles are chemically combined with a wire surface through the one or more hydrocarbon compounds. The total amount of the hydrocarbon compounds, and a lubricating oil and/or lubricating particles deposited on the wire surface is in the range of 0.1 to 5 g per 10 kg of the wire.

Wire for welding

A high-performance composite reinforcing material for optical fiber cables, exhibiting excellent protective effect when incorporated into a reinforcing component of optical fiber cables, and having a degree of flexibility applicable to curved wiring of a small radius of curvature.
