Authentic LX-F Sponge hardness foam, polyurethane foam rubber products, rubber hardness tester

LX-F type sponge durometer hardness was measured for the convenience of the customer and special custom foam material, which is suitable for the determination of soft foam, polyurethane foam rubber product hardness, this durometer hardness in the assay with the use of other different aspects, when in use, the presser foot in contact with the sample directly using its own weight as a force measuring load. ??? Second, the main performance parameters ???? pressure needle stroke range: 0 to 2.5 mm; ???? dial: 0 to 100 degrees; presser ends force:? 550mN ~ 4300mN (56 ~ 438.5g ). ??? Third, use: ???? handheld instrument middle part, the hardness is greater than the presser foot gently on flat samples (or specimens), and when the hardness of the presser foot in contact with the sample smoothly 1 second reading, then the pointer scale is the test sample (specimen) hardness value. In order to improve the measurement accuracy, the sample should be placed on a flat glass or flat, measuring only allowed once each measurement point, more than 25mm apart in different parts of the measuring points less than 5:00 on the same specimen. The measurement results are averaged, that is, the hardness of the sample material. Fourth, note when the hardness of the presser foot is in a free state, the pointer is displayed as "0", press the needle end and close contact with the presser foot flat on the glass, the pointer should be displayed as "100." Such as checking the hardness pointer can not be displayed when "0" and "100", the need to adjust to the "0" and when to use "100." ? Five samples and regulation (1) sample thickness should be between 25mm to 30mm: When the thickness is less than 25mm, can be used two stacked, but the need to ensure smooth contact surface, the total thickness of the sample thickness should still comply with the provisions of . (2) the sample size should satisfy both the length and width greater than 100mm, the measurement point and the edge of the sample distance of not less than 40mm, not less than 25mm between the measurement points, each sample measuring point less than 5:00. (3) remove the skin on both sides of the specimen thickness should be uniform, smooth surface, uniform pore distribution, no mechanical damage and impurities. ? (4) sample conditioning and testing performed in ambient conditions GB / T2941-91 regulations. Hardness after use, into the instrument box, place a dry place to prevent moisture.
