COF-01 Coefficient of Friction Tester Background The coefficient of friction pertains to the friction present between two surfaces. A lower coefficient of friction signifies that less force is needed for sliding to commence, while a higher value indicates a greater force requirement. The coefficient of friction varies based on the specific materials involved. In the context of packaging film, the coefficient of friction refers to the extent of 'slipperiness' exhibited by the packaging material when in contact with different components of the packaging machine or other materials. The management of the coefficient of friction holds significance in enhancing performance and mitigating issues during the creation, transportation, and storage of packages. Numerous factors, such as antiblock additives, corona treatment, antistatic agents, inks, varnishes, and adhesives, can influence the coefficient of friction. Application The COF-01 Coefficient of Friction Tester is designed to measure both static and kinetic coefficients of friction for a wide range of materials. These materials include plastic films, sheets, rubber, paper, paperboard, woven and non-woven fabrics, metal-plastic composite belts used in communication cables and conveyor belts, wood, coatings, brake pads, windshield wipers, shoe materials, and tires. The tester can also be adapted or modified to accommodate various other material types and testing standards. Standards: ASTM D1894, ISO 8295, TAPPI T816, GB 10006 Technical Features The COF-01 Coefficient of Friction Tester has been aiding the flexible industry since its inception. 1.It employs PLC control and an HMI touch screen for interaction. The design, of industrial caliber, assures stability and extended service life. 2.The driving mechanism is powered by a stepper motor and a precision ball lead screw. 3.It exhibits real-time test curves, and automatically records maximum, minimum, and average test results. 4.Both static and kinetic coefficients of friction are gauged. 5.Compliance with multiple test standards is incorporated. 6.A dot matrix microprinter is integrated. 7.The test plane is constructed entirely from aluminum. 8.It offers RS232 output and professional software(Optional). 9.Local language display is supported(Customized).

Product overview: CRM-8501 is an organic polymer compound of cation quaternary ammonium salt type. The advanced technology and raw materials are from developed countries. The characteristics are as below: The effective concentration is 10 times or 15 times higher than common retention acid liquid. It has better fluidity, easy & fast dissolution, no caking or granularity phenomenon. It has very good adaptability and can adapt to kinds of papers of kinds of pulps. Product function mechanism during the paper-making process 1. To neutralize the paper surface charge. The pulp and filler are of negative charges and the charges can be neutralized and decreased by adding into CRM-8501so as to form micro-floc when the potential towards zero. 2. To be inlaying effect. The electrostatic of positive charge on CRM-8501 surface can attract pulps and fillers whose surface is of negative charges. 3. To be bridging effect. Higher molecular weight and longer enough molecular chain will result in bridging between fines and fillers so as to form micro-floc. 4. The micro-floc of fines and fillers will decrease the porous structure blockages of wet paper layers and increase the permeability properties of papers. Appearance: Milky white liquid Solids content: 38�±1% pH value: 3-6 Viscosity : â?¤ 500 mPa.s Performance characteristics 1. To increase the retention rate of paper fines and fillers dramatically so as to decrease the pulp consuming qty. 2.

5052 aluminum coils is Aluminum-magnesium alloy aluminum coils. Mg is the main alloying element in 5052 aluminum coils. It is the most widely used rust-proof aluminum. The alloy is high in nature, especially fatigue resistance, plasticity and corrosion resistance, with high strength. It can not be heat-treated, the plasticity of it is good in semi-cold hardening. Itâ??s low in plasticity during cold hardening, and good in corrosion resistance with good weldability, poor machinability and polishing. The main alloying element of 5052 aluminum sheet is magnesium, and aluminum-magnesium alloy also contains a small amount of Mn, Cr, Ni, Ti, etc. Most of the Mn in the alloy forms MnAl6 except for a small amount of solid solution. In the interior of the 5052 aluminum coils, the effect of Cr is similar to that of Mn, which improves the resistance to stress corrosion cracking, improves the strength of the base metal and weld, and reduces the tendency of weld cracking, but its content generally does not exceed 0.35%. Surface Advantages of 5052 Aluminum coils: 1 - surface of 5052 aluminum coils is not allowed to have cracks, corrosion spots and traces of nitrate. 2 - The surface is allowed to have peeling, air bubbles, surface roughness. and it is also allowed to have local mechanical damage with a depth not exceeding 8% of the nominal thickness of the part where the defect is located. But the maximum depth of the defect shall not exceed 0.5 mm, and the total area of the defect shall not exceed the total area of the coils 5%. 3 - Allow the supplier to illuminate the profile longitudinally to a smooth surface. 4 - Other requirements: There are demanders and suppliers to draw up their own. Application of 5052 Aluminum coils: 5052 aluminum coils is mainly used for high plasticity with good weldability. It is also commonly used in transportation vehicles, ship sheet metal parts, instruments, street lamp brackets and rivets, hardware products, electrical enclosures, etc. It can also be used to manufacture aircraft fuel tanks, oil pipes, aerospace aluminum alloy materials, and is a typical rustproof alloy material. The atates of 5052 aluminum coils includes F, O, H12, H14,, H16, H18, H19, H22, H24, H26, H28, H32, H34, H36, H38, H111, H112, H114.
