Characteristics and Precautions of Din Abrasion Tester

Din abrasion resistance tester for elastic materials, rubber, tires, conveyor belts, soles, soft synthetic leather. The The And other materials of the quality of the wear measurement, with high performance, good reproducibility and easy operation of the characteristics. The Din abrasion resistance tester main principle is in a certain load, in a certain level of gauze, the columnar sample on the surface of the gauze across the grinding of a certain trip, by measuring the quality of the sample wear, and then calculated by the density of the sample Volume wear, in order to make the test comparable, and finally the need to use standard rubber, the test results expressed as a calibrated gauze based on the relative volume of wear or foot is expressed as a relative amount of wear Wear base.

Din abrasion tester, also known as drum grinding machine, used to determine the rubber tires, rubber shoes, tape wear resistance, to identify the quality of rubber products. During the test, the rubber material under a certain load and roller gauze on the friction, the determination of the required stroke within the sample wear. Meet GB9867, ISO4649 and DIN53516 requirements. The machine has a small sample, save time, the friction path is not repeated, the advantages of small noise.
DIN abrasion testing machine main issues:test piece can be used DIN drilling machine or standard mold forming, can not be washed test pieces.test piece thickness of not less than 2mm.Test piece thickness greater than 2mm less than 6mm, with a suitable adhesive, stick to a hardness of not less than 80IRHD, Φ16mm material (such as resin), so that the thickness of more than 6mm but their total thickness can not exceed 14mm.If the test material is loose and empty, it is best to stick on a piece of test piece with a hardness of not less than 80IRHD, Φ16mm material (such as resin glue). This allows the test piece can be firmly fixed on the chuck , While the test pieces are not deformed on the chuck, but their total thickness can not exceed 14 mmThe above is the recommended standard, please refer to the relevant standards.standard state of the test piece: before the test stand in the temperature of 23 ℃ ± 2 ℃, the relative temperature of 65 ± 2% of the state in 48 hours or more3. Number of test pieces: the same material to be tested more than three.

Multi-Functional Scratch tester For automotive interior materials

          Multi-Functional Scratch tester is applicable to all types of wiping performance test of automotive interior materials; test equipment integrated three domestic standards (fingers scraping method, a hundred grid method, and plastic scraping finger scraping method).         Scratch tester is an electronic instrument capable of measuring critical load, adhesion, scratch resistance and bond strength for a wide range of surfaces. Scratch tester measures the scratch resistance of a sliding and moving surface in the relative motion to a stylus. The stylus is forced/pressed against the moving surface with precise controlled force which is normal to the surface and tangential force at the contact has to be measured.         Scratch tester can be utilized for all type of industrial coating from the plasma layers used in semiconductor and optical technology used in decorative coatings used for automotive and consum...

Reveal the standards for textile breathability testing and let you understand it in seconds!

 Reveal the standards for textile breathability testing and let you understand it in seconds! Breathability testing is a measure of how much gas can pass through a textile. However, there is no single "optimal" air permeability value, as it depends on the specific circumstances in which the textile is used. For example, if it is used to make sportswear, it is hoped that it has good breathability; if it is used to make insulating clothes or warm clothes, it is hoped that it can block the cold well. Therefore, when testing the air permeability of textiles, the purpose of using the textile must be clearly understood in order to obtain reasonable values. In order to accurately and quickly test the true breathability performance of a sample, specially designed and developed instruments must be used. Testing methods generally include: fabric thickness (Thickness), fabric density (Density), fabric water absorption rate (Water Absorption Rate), evaporation and mass transfer (Moistur...

Test Methods of Universal Pilling Assessment Viewer (PAV)

Universal Pilling Assessment Viewer enables fabric to be assessed while still mounted on a Martindale head. The Pilling Assessment Viewer (PAV) for the textile market has been developed with the help of a major textile company in accordance to BN EN ISO 12945 standards incorporating all 3 parts and adopting the following test methods: Part 1: ICI Pilling box method (BS 5811) Part 2: Modified Martindale method (SN 198 525) Part 3: Atlas random tumble method (ASTM D 3512-96) It uses D65 Artificial Daylight (with CWF optionally available), as specified by many retailers. Other test methods can also be viewed, including those specified by major retailers. Other results of test methods that can be viewed include: BS 5811:1986 Determination of resistance to pilling and change of appearance of fabrics. ICI modified pill box for snagging Fleece appearance and surface change after washing Other test methods as specified by several major retail outlet. To optimize c...
