This model features a stationary sled with a moving plane and also comes with the option of a computer software to record data.
Introduction: Understanding and managing the coefficient of friction (COF) is vital in optimizing packaging processes across various industries. The COF-01 Coefficient of Friction Tester provides comprehensive solutions for precisely measuring COF, ensuring efficient performance and quality control throughout packaging operations. Background: The COF signifies the degree of friction between surfaces, influencing the ease of sliding between materials. In packaging, maintaining an optimal COF is crucial for smooth processing and minimizing issues during packaging creation, transportation, and storage. Various factors such as additives, treatments, and materials composition affect COF. Application: The COF-01 Coefficient of Friction Tester is versatile, catering to a wide range of materials including plastics, rubber, paper, and more. It adheres to industry standards such as ASTM D1894, ISO 8295, TAPPI T816, and GB 10006, ensuring accurate and reliable results. Formula: COF is calculated by dividing the force required for sliding by the perpendicular force between surfaces. The tester measures both static (�¼s) and kinetic (�¼d) COF, crucial for assessing stacking, cartoning, machinery processing, and other packaging scenarios. Technical Features: 1.

Background Given the extensive applications of mop materials in diverse settings, including homes, offices, and industries, rigorous quality testing is essential. While their ease of washing and high absorbency are valuable traits, consistent performance over time is vital. Quality testing ensures mops retain their absorbency and durability, upholding their effectiveness in tasks such as cleaning kitchen surfaces, windows, and furniture. This process identifies and addresses potential issues, maintaining the reliability and functionality of mops across various uses. Application COF-S1 is a specialized coefficient of friction tester for mop and cleaning materials like microfiber mop pads, sponge mops with foam blocks (cellulosic, rubber, or plastic). Friction varies based on usage for liquids, dust, and dry surfaces. The mop's friction coefficient affects its cleaning efficiency and usability. Excessive friction raises labor intensity, while too little hampers cleaning, thus requiring a balanced coefficient for optimal performance. Formula COF is determined by dividing the force needed to move one surface across another by the force perpendicular to the surfaces. It has two kinds: Static and Kinetic. Static COF �µs is measure of force required to begin movement. Kinetic COF �µd is measure of force required to maintain movement. Test Method Fix the sample cloth to its aluminum or plastic frame, then the total assembled part is placed under a certain weight. The block, together with the sample and its frame, is pulled at a speed of 500mm/min, for 500mm distance. The static and kinetic coefficient of friction are recorded. Technical Features COF-S1 Mop Cloth Coefficient of Friction Tester is a PLC controlled and HMI screen operated equipment with industrial level stability. Equipped with user designated test range, and with variable test speed, itâ??s ideal for mop manufacturers to control quality and develop new product.

Film Shrinkage Test Equipment Film Shrinkage Tester GBK-D1 Film Shrinkage test, known as linear thermal shrink test or free shrink test, is used for analyzing the effect of temperature on heat shrinkable films made from polyethylene, ethylene copolymers and their mixtures. Basically, shrinking force, contracting force and shrinking ratio can be measured in such determination. GBPI Film Shrinkage tester conforms to the multiple national and international standards: ASTM D2732 - Standard Test Method for Unrestrained Linear Thermal Shrinkage of Plastic Film and Sheeting ISO 14616 - Plastics Heatshrinkable films of polyethylene, ethylene copolymers and their mixtures Determination of shrinkage stress and contraction stress DIN 53369 - Testing of plastic films determination of the shrinking stress Film Shrinkage Test Equipment GBK-D1 is used to determination of the degree of unrestrained linear thermal shrinkage and dimensional stability at different temperatures. Widely used in industries of plastic material, plastic products, petroleum, chemicals, research institute, inspection agency and so on. Principle This tester uses the principle of air heating to connect the tested sample to the tension sensor and displacement sensor. After reaching the maximum shrinkage force, it is placed in an external test environment with an ambient temperature of 23 to cool down. The reference temperature, shrinkage force and displacement are recorded, and the recorded data can be used to determine the optimal shrinkage conditions of the film.
