Principle, Application and Type Selection of Drying Agent Film Applicator

The desiccant wet film preparer is a kind of equipment used to test the thickness of the wet film formed by the desiccant under specific conditions, which is widely used in product development and quality control in electronics, medicine, food and other industries. This article will introduce the working principle, application fields and selection points of desiccant wet film preparators, to help readers better understand and choose the equipment suitable for their needs.

Principle

The working principle of the desiccant wet film preparer is based on the hygroscopic properties of the desiccant under specific humidity and temperature conditions. Its main components include a specimen chamber, a control system and a measuring system. First, the desiccant sample to be tested is placed in the sample chamber, and then the humidity and temperature of the sample chamber are controlled by the control system to simulate different environmental conditions. Over time, the desiccant sample absorbs moisture from the air, forming a wet film. Finally, the thickness of the wet film is measured by a measuring system to evaluate the moisture absorption of the desiccant and the formation of the wet film.

Apply

In the production process of electronic products, desiccant wet film preparers are often used to test the wet film thickness on the surface of electronic components and circuit boards to evaluate the moisture resistance and stability of the product.In the pharmaceutical manufacturing process, desiccant wet film preparers can be used to test the wet film thickness of pharmaceutical packaging materials to ensure the quality and safety of pharmaceutical products.In food processing and packaging, desiccant wet film preparers can be used to test the wet film thickness of food packaging materials to extend the shelf life of food and prevent food spoilage.
