Eco-friendly & Multi-functional Alkaline Degreasing Additive

LW-31 Eco-friendly & Multi-functional Alkaline Degreasing Additive is a colorless to light yellow transparent liquid that serves multiple important roles in the field of aluminum treatment. As an Anodizing Agent, it plays a crucial part in the Aluminium Anodizing Process. This degreaser is specifically designed for the pretreatment process of aluminum and its alloy powder coating.

Functioning as an effective aluminum cleaner, LW-31 can efficiently remove the natural oxide film, oil stain, and floating sand from the surface of sand-blasted aluminum profiles. This results in obtaining a clean, uniform, delicate, and soft metal surface, which is essential for subsequent processes. Although not primarily an aluminum brightener, the removal of these contaminants can enhance the overall appearance of the aluminum surface, giving it a cleaner and more appealing look.

When comparing the LW-31 alkaline degreasing process with the traditional alkaline etching process and acidic degreasing, the advantages of LW-31 become evident. Traditional acidic degreasing, which often contains fluorine, is not environmentally friendly and harmful to the body. It generates a large amount of acidic fluorine-containing wastewater, with about 1.5-2 tons of wastewater produced per ton of aluminum. Additionally, the production of a significant amount of acid mist during processing not only worsens the working environment for production personnel but also damages workshop equipment and affects the oxidation and electrophoresis processes.

In contrast, LW-31 is a fluorine-free and environmentally friendly option. It does not produce acidic wastewater; instead, the waste water from this process can be used to neutralize the waste acid water from other processes, saving on wastewater treatment costs. Moreover, it does not generate acid or alkali mist, resulting in less corrosion to the equipment.

After the anodizing process is completed, when it comes to Cleaning Anodized Aluminum, the pre-treatment with LW-31 can have a positive impact. A clean surface achieved through the degreasing action of LW-31 makes the anodized layer adhere better and reduces the likelihood of contaminants adhering during the anodizing process. This simplifies the task of Cleaning Anodized Aluminum. Although not a traditional aluminum etchant, the degreasing action of LW-31 can be seen as a form of surface preparation that is somewhat related to the function of an etchant in getting the aluminum surface ready for further treatment in the Aluminium Anodizing Process. Overall, LW-31 Eco-friendly & Multi-functional Alkaline Degreasing Additive is a valuable product that offers environmental and practical benefits in the treatment of aluminum and its alloys.
