Coefficient Of Friction Tester Friction Tester

Coefficient of Friction Tester measures the static and kinetic friction coefficient of plastic films, sheets, rubber, paper and paper board, medical device, thread, wires etc. The COF tester can also be customized for many types of materials as well. COF Test Standards ASTM D1894, ISO 8295, TAPPI T816, GB10006

The standard C0055-M1 unit can measure Static COF (peak) from a resting position and continue to move testing surfaces in a relative motion to give an accurate kinetic COF (dynamic) result. This model features a stationary sled with a moving plane and also comes with the option of a computer software to record data.

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. Standards ISO 14616, ASTM D2732, DIN 53369

The FPT-01 Friction and Peel Tester is a versatile and multifunctional device designed for various applications: Measurement of Coefficient of Friction: It accurately measures both static and kinetic coefficients of friction for a wide range of materials, including plastic films, sheets, rubber, paper, paperboard, PP woven bags, fabrics, composites, and more. This capability is valuable for understanding how materials interact with each other and with various surfaces. Delicate Peeling Force Test: The tester can perform delicate peeling force tests on materials such as release paper, adhesive tape, medical adhesives, composite films, and protective films. This feature is essential for assessing the ease of separation between different layers of materials, ensuring product quality and performance. The FPT-01 Friction and Peel Tester is a versatile instrument that serves as a valuable tool for quality control, product development, and research in industries dealing with a wide range of materials, from packaging to medical applications. System Description FPT-01 Friction and peel tester has a fixed loadcell position, with a protection cover. A movable plane is installed firmly to ball lead screw. The sled is to put on sample sticking to the plane, which is then connected to loadcell, with a filament. When performing peeling test, as the force is small, the right sample clamp is stuck to plane, using double side type. Then a separation action is performed to peel the sample and force is recorded during the process. Technical Features FPT-01 Friction and peel tester is a PLC-controlled unit with industrial-grade stability and operates through an intuitive HMI touch screen interface. The precision ball lead screw mechanism ensures consistent speed and displacement control. The system offers two distinct testing methods: one for measuring the coefficient of friction (COF) and another for assessing peeling forces. In COF tests, precise free speed settings are available, while peeling tests consider parameters that influence peeling results, such as initial and tail portions. Other features 1. Real-time data analysis and display, including results and graphical curves. 2. Compliance with various test standards. 3. Integration of a dot matrix micro printer. 4.
