    摘要: A method of measuring fracture strength of a superabsorbent polymer in order to predict a generation amount of fine powder is provided. Effects of many different treatments for increasing strength of the superabsorbent polymer may be evaluated by measuring a force at a time point when single particles having a uniform particle size of the superabsorbent polymer are fractured by pressurizing the particles at a constant rate within a predetermined range.

    摘要: The invention relates to a method for measuring the tenacity K
    c of a material, comprising the following steps: placing a sample of said material, having the shape of a parallelepiped rectangle through the middle of which a central hole extends, between two jaws of a clamping device, each of said jaws engaging with a distant end of the sample; moving the two jaws together so as to exert a force at each of said ends until the sample has completely broken; measuring the variations during the clamping on the basis of the time of the clamping force exerted at each end of the sample; determining the maximum value F
    0 of said clamping force; marking three separate areas on the surface of one of the breaking surfaces, i.e. a first area close to the hole having a first type of embossment, a second area having a second type of embossment, and a third area having a third type of embossment that is less pronounced than the second type; measuring the distance L
    0 between the edge of the hole and a transition line separating the second area from the third area; and calculating the parameter K
    c on the basis of the force F
    0 and distance L
    0 .

    摘要: A cloth evaluation apparatus can grasp the piercing property and the cutting property with a cloth in advance. The cloth evaluation apparatus (1) comprising: a measuring member (21,71,81) having, on its distal side, a measuring part (22) to pass through a cloth (c, d); a cloth/measuring part moving means (30, 40) for moving the cloth (c, d) or the measuring member (21, 71) so that the measuring part (22) passes through the cloth (c, d); a cloth supporting means (23, 23', 31') for supporting the cloth (c, d) at around a passing-through point, in the cloth (c, d), of the measuring part (22) from both sides of the cloth (c, d) when the measuring part (22) passes through the cloth (c, d); and a load detecting means (25) for detecting a load being applied to the measuring member (21, 71) while the measuring part (22) passes through the cloth (c, d). The measuring part (22) includes a piercing force measuring portion (22A, 72A) whose outer diameter gradually decreases toward its acute tip (22A') and, after the tip (22A') sticks the cloth (c, d), the piercing force measuring portion (22A, 72A) can pass through the cloth (c, d) while expanding a grain of the cloth (c, d). The measuring part (22) also includes a cutting force measuring portion (22B, 72B) adjacent proximally to the piercing force measuring portion (22A, 72A), the cutting force measuring portion (22B, 72B) having a shear face (22Bb) which can push a part of the cloth (c, d) in the passing direction to separate the part from the cloth (c, d) as the measuring part (22) passes through the cloth (c, d).

    摘要: There are provided a strength evaluation method of a die casting product capable of appropriately evaluating the strength of the die casting product, and a die casting product in which the strength is evaluated by the strength evaluation method. A breakage test is performed by a simple strength tester after casting, and then, a strength reduction ratio is estimated based on an area ratio of cold flakes in a broken surface obtained by broken surface observation.
    Alternatively, ultrasonic flaw detection is performed for an internal defect in a predetermined range of a high stress portion of the die casting product, calculated by stress analysis in advance, and the die casting product is evaluated to have a predetermined strength when a defect ratio obtained by dividing a total area of the internal defect in the predetermined range by a total defect detection area is less than or equal to a predetermined value.

    摘要: The invention relates to a method for determining the breakability and the breaking accuracy of a tablet (8). According to said method, a tablet which is provided with at least one breaking notch (12) on at least one side is broken along the breaking notch. A fixing pin (2) is placed along the breaking notch on the side of the tablet, which comprises the breaking notch, such that the face of the tablet, which is located opposite the breaking notch, is fixed relative to a breaking notch in such a way that the breaking notch and the fixing pin lie parallel to each other, whereupon force is applied to the tablet until the tablet breaks. The invention also relates to a device that is suitable for carrying out said method.
