Powder coating is an efficient and environmentally friendly coating technology widely used in industrial production. In the process of powder coating, dip tank powder coating and ordinary powder coating are two common coating methods. In this paper, the characteristics and differences between these two powder types will be analyzed in detail to help readers better understand the dip-tank powder coating technology.

I. Characteristics of common powder coating

Ordinary powder coating is a widely used powder coating method in industrial production. Its characteristics are as follows:

1. Powder type: The powder used for ordinary powder coating is conventional powder, usually composed of resin, pigment, filler, etc. 2.

2. Spraying method: In the ordinary powder coating process, the powder is sprayed on the surface of the object by electrostatic adsorption to form a uniform coating. 3. Curing method: The ordinary powder coating is applied to the surface of the object by electrostatic adsorption.

3. Curing method: Ordinary powder coating usually needs to be cured at high temperature to ensure the adhesion and durability of the powder coating.

4. Scope of application: Ordinary powder coating is suitable for all kinds of metal products and some non-metallic products, such as furniture, automobile parts, electrical appliance shells and so on.

Characteristics of dip-tank powder coating

Dip tank powder coating is a relatively new coating technology, its characteristics are as follows:

1. powder type: dip tank powder coating powder for the impregnated powder, which is different from the ordinary powder in composition and morphology.

2. impregnation mode: in the dip tank powder coating process, the object is first immersed in the pre-prepared dip tank, so that the surface of the full adsorption of impregnated powder, and then curing treatment.

3. Curing method: The curing of dip tank powder coating usually uses a low-temperature curing process, which helps to reduce energy consumption and is suitable for some objects that are sensitive to high temperatures.

4. Application scope: Dip tank powder coating is mainly applied to special materials and shapes, such as pipes, fittings, shaped parts and so on. It has some advantages in coating effect and coating speed.

Difference between dip-tank powder coating and ordinary powder coating

1. Different types of powder: Ordinary powder coating uses conventional powder, while dip-tank powder coating uses impregnated powder. This makes the dip-tank powder coating more suitable for special materials and shapes. 2.

2. Different curing methods: Conventional powder coating usually requires high-temperature curing, while dip-tank powder coating adopts low-temperature curing, which helps to reduce energy consumption and is suitable for objects that are sensitive to high temperatures.

3. Different application scope: Ordinary powder coating is widely used for coating all kinds of metal and non-metal products, while dip-tank powder coating is mainly used for coating special materials and shapes, such as pipes, pipe fittings, shaped parts and so on.

4. Different coating methods: Ordinary powder coating adopts electrostatic spraying, while dip tank powder coating makes the surface of the object fully adsorb the powder through dipping tank, and then curing treatment.

Conclusion: 

Ordinary powder coating and dip tank powder coating are two common powder coating methods, they have some differences in powder type, curing method, application range and coating method. When choosing the coating method, enterprises should consider the advantages of each according to the characteristics of the product and coating requirements, in order to achieve the best coating effect and production efficiency.
