Application of Lab Film Applicator to Lubricating Material on Aramid Fiber Cloth [Video Demonstration]

NBCHAO experimental film coating machine has 18 kinds of martial arts and thousands of adaptations, which has come to a new application. This issue is to apply lubricant on aramid fiber, and use a combination of fixture fixing substrate + wire rod coater.

Aramid fiber is a high-performance synthetic fiber with excellent heat resistance, chemical corrosion resistance, high strength and high modulus. It is widely used in high temperature environments, protective clothing, body armor, cables and other fields. In specific application scenarios, aramid fiber cloth may be coated with lubricating materials to increase its performance and function.

For example, the following application purposes:

Reduce friction: Coating appropriate lubricating materials can reduce friction between aramid fibers, reduce material wear and heat generation, thereby extending service life.

Improve wear resistance: Lubricating materials can form films under high friction and high load conditions, improving the wear resistance and heat resistance of aramid fibers.

Increased chemical resistance: Some lubricating materials have chemical resistance that can provide protection against chemicals in the face of aramid fibers.

Improve surface properties: Lubricating materials can improve the surface properties of aramid fibers, such as making them easier to wet and reducing static electricity.

In this application, the aramid fiber is relatively thick, so it can be fixed with a fixture fixing material or tape. In addition, the viscosity of the lubricating material is not high, and a mayer-rod is used for scraping to ensure higher coating accuracy.

Let's take a look at the specific coating experiment process of NBCHAO technical engineer.

It can be seen from the video that although there are a small number of folds on the substrate, it does not affect the coating effect of the laboratory coating machine, and the uniformity of the coating film is still very good.
