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.
