As one of the key links in the surface treatment of aluminum products, the correct methods and steps of using sealing additive agent are crucial to the performance and quality of the product. However, for many consumers and industry practitioners, there is still some confusion about how to use sealing additive agent correctly.

Today, we will explore the methods and steps of using sealing additive agent in depth, provide practical guidance and suggestions for consumers and the industry, and help everyone better apply sealing additive agent to improve the performance and quality of products.

1. The role and principle of sealing agent

Before understanding how to use sealing agent correctly, you first need to understand the role and principle of sealing additive agent. Sealing additive agent is usually used on the surface of aluminum products after anodizing treatment. Its main function is to fill the micropores and microcracks of the oxide layer, enhance the density and corrosion resistance of the oxide layer, and improve the corrosion resistance and surface quality of the product.

2. How to use sealing additive agent

The correct use of sealing additive agent is a key step to ensure product performance and quality, which generally includes the following aspects:

★  Pretreatment: Before using sealing additive agent, you first need to clean and treat the surface to ensure that the surface of the aluminum product is clean and dust-free so that the sealant can fully penetrate into the micropores of the oxide layer.

★ Prepare sealing liquid: According to the formula ratio and process requirements of the sealing additive agent, prepare the sealing additive agent with an appropriate amount of solvent or water to prepare the sealing liquid.

★ Impregnation treatment: Immerse the aluminum product in the sealing liquid to ensure that the surface of the product is completely covered by the sealing liquid, and then perform the immersion treatment under certain temperature and time conditions to allow the sealant to fully penetrate into the oxide layer.

★ Drying and curing: The aluminum product after the immersion treatment needs to be dried and cured so that the sealant forms a dense sealing film and improves the sealing and corrosion resistance of the oxide layer.

★ Post-treatment: After drying and curing, the aluminum product is subjected to necessary post-treatment, such as cooling, cleaning and packaging, to ensure the quality and appearance of the product.

3. Precautions for sealing agent

When using sealing additive agent, you also need to pay attention to the following aspects:

★ Select a suitable sealant: Select a suitable sealing additive agent according to the product requirements and the use environment. Different types of sealants have different performance and application ranges.

★ Strictly control process parameters: The use of sealing agent requires strict control of process parameters, including immersion time, temperature and concentration, to ensure the sealing effect and product quality.

★ Avoid cross contamination: When using sealing additive agents, cross contamination with other chemicals should be avoided to avoid affecting the sealing effect and product performance.

4. Practical application cases

In the fields of aerospace, automobiles, construction, etc., sealing agents are widely used in the surface treatment of aluminum products. For example, in the aerospace field, after the aircraft parts are treated with sealing additive agents, the corrosion resistance and service life of the products can be improved to ensure flight safety.

5. Future development trends

With the continuous advancement of science and technology and the continuous improvement of market demand, sealing additive agent technology will continue to innovate and develop. In the future, more sealing additive agents with better performance may appear, providing more options and better solutions for the surface treatment of aluminum products.

In summary, the correct use methods and steps of sealing additive agents are crucial to ensure product performance and quality. When consumers and industries apply sealing agents, they need to fully understand their working principles and usage methods, and strictly control process parameters to ensure the effect and quality of product surface treatment.
