What is the difference between grandstand tensile film baking paint and spray paint

Mondo Cars Updated on 2024-01-31

With the increase of people's pursuit of architectural aesthetics and personalized demand, as a new type of architectural form, the tensile membrane structure of grandstand has been widely used in stadiums, convention and exhibition centers, commercial centers and other places. In the surface treatment of grandstand tension film, baking paint and spray painting are two common processes, they have their own characteristics, and we will compare these two processes from many aspects.

First, the principle of the process.

Baking paint is a coating process in which paint is cured on the surface of a substrate after being baked at a high temperature. In the baking process, the substrate is fed into the baking booth and baked at a high temperature for a certain period of time to dry the paint and adhere to the surface of the substrate. Because the paint is treated at high temperatures, the intermolecular adhesion is stronger, so it has high adhesion and durability.

Painting is made by spraying paint evenly on the surface of the substrate through a spray gun, and drying it naturally or at low temperature. When painting, the paint is atomized into tiny particles by a spray gun and adheres to the surface of the substrate to form a coating. The painting process has the advantages of fast application speed and uniform coating, but the adhesion is relatively poor.

Second, the appearance effect.

There are also differences between baking paint and spray paint in terms of appearance effect. The coating of baking paint is thicker, the surface is smooth and flat, the gloss is high, the color is full and bright, and it has a good visual effect. The coating of spray paint is thinner, the surface is relatively rough, the gloss is lower, and the color is relatively dull. Therefore, for occasions that require high gloss and bright colors, baking paint is more suitable.

Third, the use of performance.

In terms of anti-corrosion, anti-rust, weather resistance, etc., there are also differences in the performance of baking paint and spray paint. Because the baking paint is baked at high temperatures, the intermolecular adhesion is stronger, so it has better weather resistance and corrosion resistance, and is better able to resist various factors in the natural environment. However, the weather resistance and anti-corrosion performance of spray paint are relatively poor, and it needs to be used in a relatively dry and pollution-free environment.

4. Scope of application.

Baking and spray paint are suitable for different substrates and occasions. Due to its strong adhesion and good durability, it is suitable for hard substrates such as steel, aluminum plate, glass fiber reinforced plastic, etc., and is often used in building exterior walls, grandstand seats, billboards and other fields. Spray painting is suitable for various soft materials and metal surface treatment, such as wood, plastic, steel plate, etc., and is often used in interior decoration, furniture manufacturing and other fields.

Fifth, the cost of construction.

In terms of construction costs, there is also a difference between baking paint and spray painting. The paint baking process requires the use of large paint baking equipment, and requires a lot of energy and time to bake at high temperatures, so the cost is relatively high. The painting process is simple and easy, the construction speed is fast, and the cost is relatively low. However, it should be noted that baking paint has an advantage in terms of service life due to its better durability and adhesion, and may be more economical in the long run.

To sum up, there are differences between baking paint and spray paint in terms of process principle, appearance effect, use performance, scope of application and construction cost. In practice, it is necessary to select the appropriate coating process according to the specific needs and occasions. For occasions that require high gloss, vivid colors, durability and high adhesion, such as grandstand seats, baking paint is more advantageous;For some occasions that require fast application, uniform coating and low cost, such as interior decoration, furniture manufacturing and other fields, spray painting is more suitable.
