LX-D Shore durometer Shore hardness of rubber is vulcanized rubber and plastic products to measure the hardness instrument, which has A-, D-, C-type three forms. A and D, respectively, for low hardness and high hardness rubber hardness testing. C is suitable for a compression ratio of 50%, the stress is 0.049MPa above, with the use of rubber, plastics containing a foaming agent made of a microporous material hardness shoe testing. The hardness of the Executive GB/T531, GB2411, HG/T2489, JB6148 relevant provisions. When D durometer test pressure in the zero reference plane, because the rigid head under heavy load is easily pressed into the plane, and can not be read accurately and must be placed in a standard reference gauge block surface, operation hand-held hardness tester, pressure gauge blocks for the quasi-center hole, depressed hardness tester, hardness tester when sufficient pressure gauge block and plane dedicated entirely timely pressure, hardness should show 10 ± 1HD (2.25 ± 0.003mm thickness gauge block is equal to hardness indentation depth when pressed into 10HD), if not accurately show the same hardness can not be used. The measurement frame is my factory design and production of a new generation of products Optical Brinell hardness, its hardness test principle is more scientific, so Shore D hardness durometer rubber parts means high hardness measurement in the determination of the shelf, The test stability and accuracy will be further improved and increased cross-wall lift fine adjustment mechanism, making the operation more convenient. Weight: 0.5 (kg) test force :0-44 .5 (N) Model: LX-D Product Type: Shore hardness Brand: tin crystal custom processing: Measuring range :0-100HD 435 hardness tester design: 0-20N between the pressure range. Equipment placed on the test surface. So that it rests on two guide wheels, marking wheel locked in a position to press the preset spring pressure on the surface of the spring strength range can be divided into three parts, each containing a replaceable spring. Range 1:0-3 N Sensitivity: 0.1 N Scale 2:0-10 N Sensitivity: 0.5 N Scale 3:0-20 N Sensitivity: 1.0 N Germany 435 hardness tester operation method: Scratch tool is circular, with lock tight means, made of a special plastic or metal. Mounted on the screw, get pressure from a coil spring, spring provides an adjustable plastic first round choice test based on Rockwell hardness test requirements, such as plastic wheels for scratch resistance test, a copper wheel or other special wheel for metal scratches. After tightening the screws, mark the wheel does not rotate, and then set the appropriate pressure springs provide a needed. The instrument is then pressed down on the test surface, the guide wheel contact with the surface. The instrument is moved a distance (a few centimeters), the rolling surface of the wheel, to produce a rapid movement of the scratch, the test result is a spring force in Newtons. This force must be generated a visible trace, but not cracks or scratches. If the purpose of the so-called metal marker effects, the results will be expressed as the surface of a black or gray print timing spring force. Note: The use of tags in the wheel will wear Shore hardness of rubber, during a test 100, their position must be changed. To move forward along the periphery of 2mm, previously used tags round the point should be added to a scratch mark.
