Plastic Film Friction Coefficient Tester - Technical Literature

Plastic Film Friction Coefficient Tester - Technical Literature Friction coefficient refers to the ratio of the friction force between two surfaces and the vertical force acting on one of them
.

It is related to the roughness of the surface, not to the size of the contact area
.

Sliding friction is generated by
the relative sliding of two objects in contact with each other.

According to the nature of the movement, it can be divided into dynamic friction coefficient and static friction coefficient
.

If the two surfaces are stationary to each other, the contact between the two surfaces will form a strong binding force - static friction force, unless the binding force is destroyed to make one surface move against the other surface, and the ratio of the destructive binding force - the force before the movement to the vertical force on one surface is called the static friction coefficient μs
.

The dynamic friction factor (or dynamic friction coefficient) is the ratio
between friction and positive pressure when objects in contact with each other make relative motion.

When the object is in horizontal motion, positive pressure = gravity
.

The dynamic friction factor of different materials is different, and the rougher the object, the greater the
dynamic friction factor.

The coefficient of friction is an important indicator
for examining plastic packaging films.

Because the friction in the packaging process is often both a power and a resistance, its size should be controlled within the appropriate range
.

The friction coefficient of the inner and outer surfaces of the film is generally required to be between 0.
2-0.
4, and the external/external friction coefficient > the internal/internal friction coefficient
.

The tribological properties
of a film or sheet specimen can also be measured when it slides on itself or on another substance.

The friction coefficient tester produced by Jinan Sanquan Zhongshi Experimental Instrument can be used to detect the dynamic friction coefficient and static friction coefficient, and is suitable for measuring the static friction coefficient and dynamic friction coefficient when sliding plastic film and flakes, rubber, paper, cardboard, woven bags, fabric styles, metal material composite belts for communication cables and optical cables, conveyor belts, wood, coatings, wipers, shoe materials, tires and other materials
.

By measuring the smoothness of the material, the production quality process index of the material can be controlled and adjusted to meet the requirements of
product use.

It can also be used to measure
the smoothness of cosmetics and other cosmetics.
