摘要： PURPOSE:To carry out molding under low pressure and low temperature in the compression molding process, simplify a molding device and make the composition of the device inexpensive by mixing ultra-high-polymeric polyethylene powder and a small quantity of liquid organic compound. CONSTITUTION:2 - 50 pts. wt. of a liquid organic compound having the boiling point higher than the boiling point of polyethylene is mixed preliminarily with 100 pts. wt. of ultra-high-polymeric polyethylene powder having limiting viscosity of 5 - 50 dl/g in decalin at 135 deg.C at the temperature lower than the melting point of polyethylene powder, a then the mixture is fed between a couple of endless belts 5 and 6 facing each other vertically. Then, the same is moved while being pinched by the endless belts 5 and 6, and continuous compression molding is carried out at the temperature lower than the melting point of the mixture by a pressurizing means 7 installed on the inner sides of endless belts 5 and 6, and rolled and then stretched to manufacture a high strength and high elasticity modulus polyethylene material.

摘要： PURPOSE:To enhance the adherence with member to be lined by a method wherein film or the like having ultra-high-molecular-weight polyethylene layer is wound round a hollow or solid barlike body or the like in rolls under the condition that the edge faces of the rolls abut against one another and, after that, one roll is overlapped to the adjacent roll. CONSTITUTION:A sheet 1 having broad and/or narrow ultra-high-molecular- weight polyethylene is wound round a hollow pipelike body 2 at the edge face abutting part 3 so as to produce the number of rolls corresponding to the length of a pipe. Next, one roll is overlapped so as to join to the adjacent roll at joints 4 by inclining horizontally stepwise with the preferable angle of inclination alphaof 10-80 deg.. Next, heat resistant material such as glass cloth or the like is wound on the outer periphery of the rolls. Finally, the ultra-high-molecular- weight polyethylene layer is thermally and integrally fused to the pipe at a temperature higher than the melting point of ultra-high-molecular-weight polyeth ylene.

摘要： PURPOSE:To simplify operation by forming flat square-enclosure forms by metallic latticed forms with a bent section and installing the enclosure forms on the face of a slope in a single operation manner. CONSTITUTION:The title enclosure forms are composed of oblong latticed forms 5, which are assembled by a required number of metallic wallings 1, in which sectional shapes are formed in a U form or a V form and bent sections 2 are shaped at necessary positions and which are arranged in parallel at intervals, and metallic studs 3, in which these wallings 1 are bonded integrally, and have bent sections 6. The latticed forms 5 are bent to back while the open side edges of the wallings 1 are directed outward. The latticed forms 5 are constituted in square-shaped enclosure forms, in which both ends are closed by connection and the bent sections 6 and connecting ends 9 form corner sections.

摘要： PURPOSE:To lighten forms for sloped forms and impact the strength of rigidity and bendability by utilizing a metallic blank, in which a sectional shape is formed in a U shape or a V shape and which has required length, as a walling. CONSTITUTION:The required positions of a metallic blank, in which a sectional shape is formed in a U shape or a V shape and which has necessary length, are formed partially in a bendable form, thus manufacturing walling 1. A plurality of the walling 1 are arranged in parallel while bent sections 2 are positioned at the same position in the vertical direction at regular intervals. These wallings 1 are connected mutually by studs 3 at regular intervals, thus constituting oblong latticed forms with bent sections 6.

摘要： PURPOSE:To enhance the wear resistance and the like of hollow body by a method wherein film or the like having ultra-high-molecular-weight polyethylene layer is wound round a heat resistant core in several rolls under the condition that their edge surfaces abut against one another and, after that, one roll is overlapped to the adjacent roll. CONSTITUTION:Sheet 1 having broad and/or narrow ultra-high-molecular-weight polyethylene is wound round a heat resistant core 2 at the edge surface abutting part 3 so as to produce the number of rolls corresponding to the length of a pipe. Next, one roll is overlapped to the adjacent roll by forming the joining part 4 so as to fit one roll to the adjacent roll horizontally stepwise with the angle of inclination alpha. The angle of inclination is preferably 10-80 deg. or more preferably 25-70 deg.. Next, heat resistant material such as glass cloth or the like is wound on the outer periphery of the rolls and fixed at both of its ends. Finally, the ultra-high-molecular-weight polyethylene layer is thermally fused into an integral body at a temperature higher than the melting point of ultra- high-molecular-weight polyethylene.

摘要： PURPOSE:To improve the corrosion resistivity and the wear resistivity of rail by mounting the rail made of synthetic resin which has a small friction coefft. and is excellent in wear resistivity on the slid surface, which is brought into contact with flight plates, of the track rails to guide the flight plates disposed in a settling pool. CONSTITUTION:The flight plates 12 circulated through the upper and lower part of the settling pool 1 with an endless chain 7 scrapes the sediments settled in the settling pool 1 in one direction. The synthetic resin rail 16 consisting of the resin having a small friction coefft. and excellent in wear resistivity, such as extra-macromolecular PE, is detachably mounted at least on the slide- contact surface, which is brought into contact with the flight plates 12, of the track rails 9-11 to guide the flight plates 12. As a result, this method improves the corrosion and the wear resistivity of the rails laid in the settling pool, reduces the exchanging frequency of shoes 14, 15 as the sliding frictional resistance between the flight plates circulatingly moved and the track rails is small, and sharply lighten the energy of power, such as the driving power.

摘要： PURPOSE:To improve strength and rigidity by forming a laminate by laminating an adhesive layer containing an olefin resin modified by unsaturated carboxylic acid or its derivative by a stretched ultrahigh MW polyethylene layer. CONSTITUTION:Polyethylene with an ultrahigh MW whose intrinsic viscosity measured in decalin at 135 deg.C is within the range of 5 - 50 dl/g is stretched at temp. not reaching its m.p. to form a stretched polyethylene layer. An adhesive resin layer obtained by modifying an olefin polymer layer with unsaturated carboxylic acid or its derivative is laminated to the stretched polyethylene layer and both layer are compressed and integrated using a press molding machine adjusted to temp. equal to or high than the m.p. of the adhesive layer but not reaching the m.p. of the stretched polyethylene layer to form a laminate. The obtained laminate has high strength with no anisotropy.
