Principle, Application and Selection of Undercoat Film Applicator

The primer wet film preparer is an instrument used to test the thickness of the wet film formed by the paint primer under specific conditions. It is widely used in quality control and product development in the paint industry. This article will introduce the working principle, application fields and selection points of the primer wet film preparer.

principle

The working principle of primer wet film preppers is based on the flow and curing properties of the paint under specific conditions. Its main components include paint supply device, coating knife and Thickness Gauge. First, load the paint primer to be tested into the paint supply container, and then use a coating knife to evenly apply the paint on the surface of the sample. After coating is completed, use a Thickness Gauge to measure the wet film thickness of the primer to evaluate the coating performance and quality.

application

In the coating production process, the primer wet film preparer is used to evaluate the fluidity and coating performance of the coating, guide the optimization of the production process and adjust the product formula, thereby improving the production efficiency and product quality of the coating. During the coating construction process, the primer wet film preparer can be used to detect whether the coating thickness meets the requirements, thereby ensuring the quality of coating construction and the performance of the coating. By monitoring the wet film thickness in real time, construction parameters can be adjusted in time to improve product quality. In the process of coating product research and development, the primer wet film preparer can be used to evaluate the coating performance and quality of different formula coatings and guide the development and improvement of new products to meet the needs of different customers.

Key points for selection

The coating methods of the primer wet film preparer include manual coating and automatic coating. Choose the appropriate coating method according to actual needs. Manual coating is suitable for the preparation of small batches of samples, while automatic coating is suitable for mass production needs. Different application scenarios have different accuracy requirements for wet film thickness measurement. Therefore, when selecting, you need to consider whether the measurement accuracy meets the actual needs to ensure the accuracy and reliability of the test results. The coating range of the primer wet film preparer is usually limited by the size of the coating knife and the capacity of the paint supply device. Therefore, when selecting the model, it is necessary to select an appropriate coating range based on the size of the sample to be tested and the coating requirements. For applications that require frequent coating and measuring operations, ease of operation is an important consideration. Therefore, choosing a primer wet film preparer that is simple to operate and easy to maintain can improve work efficiency and production efficiency.

To sum up, the primer wet film preparer, as an important paint testing equipment, plays an important role in the fields of paint production, quality control and product research and development. The correct selection of a suitable primer wet film preparer is of great significance to improving product quality and production efficiency.
