The application viscosity of the coating is the fundamental factor to ensure the control of the coating film, which is very important for the stability of the coating process and the quality of the coating film. When we talk about paint application viscosity, we are referring to controlling the precise amount of paint during the coating process to ensure that the quality and performance of the final coating is up to standard.

If the construction viscosity is too low, it means that the amount of paint is too small when the coating machine applies the paint to the substrate, such as strip steel. This leads to problems: the amount of paint adhered to the strip surface is not enough, and the film thickness cannot meet the specified standards. This can result in a weak coating that does not provide the required protection or performance, which can be disastrous for some special-purpose coatings. On the other hand, if the construction viscosity is too high, it means that the amount of paint is too much. This can lead to problems: too much paint sticks to the surface of the strip, resulting in a thick film. Coating film too thick can bring a number of problems, including increased paint cost, reduced flexibility of the film, increased drying time, and defects in the film surface. These problems will not only affect the quality of the product, but also may affect the appearance of the product, especially in the field of painting, color difference performance is crucial.

Method for stable control of paint application viscosity
In order to ensure stable control of paint application viscosity, the coating process requires a high degree of accuracy and monitoring. The following are some common methods and techniques used to maintain the stability of construction viscosity:

Automatic coating system

Modern coating equipment is often equipped with automated systems that can monitor and control the coating process to ensure that the viscosity is within an acceptable range.

Coating head design

The design and selection of coating head is very important to control the construction viscosity. Different head designs are suitable for different types of coating tasks and can help ensure an even distribution of paint.

Accurate paint supply system

Coating machinery’s paint supply system requires precise control of the flow of paint to meet the required viscosity requirements.

On-line monitoring and feedback control

Use sensors and monitoring equipment to monitor the construction viscosity in real time and perform feedback control based on the monitoring results to ensure stability.

Regular calibration and maintenance

Coating equipment is calibrated and maintained regularly to ensure its performance and accuracy.
