Painting Thickness Meter | Used in Plastic Film Thickness Detection
In daily life, plastic films can be seen everywhere, with superior functions and wide application. Usually the actual performance of the plastic film is closely related to the film thickness. People in the industry will use a painting thickness meter to test its accurate data.
Plastic film is the most common kind of daily necessities, agricultural supplies and industrial supplies. Its basic performance often determines its practical use. As one of the most important physical parameters of plastic film, film thickness can be measured by a painting thickness meter in a short time. Painting thickness meters are widely used in the field of plastic film thickness detection. Painting thickness meter can be frequently seen in film manufacturers and quality inspection departments.
First of all, we will briefly introduce the nature and use of plastic film: plastic film is a transparent material made of polyethylene, resin and other raw materials, which can transmit light well and can be used as various covering layers. It can play a considerable role in food, medical, chemical and other industries.
In general, the thicker the plastic film, the stronger the toughness and the crack resistance. Thick plastic film is also prone to problems such as air permeability. We often classify plastic films according to their materials. Common ones include polyester films, nylon films and polyethylene films.
Plastic film manufacturers will find in actual operation that multilayer films often have uneven thickness problems. Plastic films that are too thin to break when they are pulled. Both the hardness and ductility are not strong enough. With the increase of plastic film layers, it is difficult to guarantee the transparency of some films. But the plastic film thickness is not absolute, but is determined according to its actual use. Under the guarantee of basic tensile strength, the thinner plastic film can save costs and improve the usability and aesthetics. Therefore, the thickness control of the plastic film is of practical production significance. It should be measured with a painting thickness meter.
For farmers planted in greenhouses, plastic films with appropriate thickness can effectively transmit light and improve the photosynthesis efficiency of plants. The plastic film with strong toughness and equivalent thickness also has good protection ability, which can block the external ultraviolet radiation, the sand and dust. Thin plastic film in a greenhouse is easy to tear and open, with poor oxidation resistance and barrier properties.
Theoretically, the basic unit of measurement for plastic films is micrometers or filaments. A filament is equivalent to ten microns. When we use a painting thickness meter to measure, we can significantly improve the precision and accuracy of film thickness control. It does not cost too much to measure and it has economical features.
In professional plastic film manufacturers, they usually prepare their own painting thickness meters. This painting thickness meter is specially used to detect the plastic film thickness. It has high sensitivity and wide range. Linshang LS221 painting thickness meter uses very advanced digital probe technology, which can maintain zero stability for a long period of time and does not drift. When in use, the operator does not need frequent zero adjustment and its precision can be greatly guaranteed.
