Two Acids Chemical Polishing Additive (Yellow Smoke-free)

LW-38 Two Acids Chemical Polishing Additive (Yellow Smoke-free) is a dark brown to black clear liquid that holds a significant position in the field of aluminum profile treatment. As an Anodizing Agent, it is primarily suitable for the chemical polishing treatment of aluminum profiles with various surface finishes such as sanding surface, brushing surface, glossy, and mechanical polishing effect.

 

In the Aluminium Anodizing Process, LW-38 plays a crucial preparatory role. By enabling the aluminum profiles to achieve a high gloss and mirror effect similar to that of the three acids chemical polishing process, it helps create an ideal surface condition for subsequent anodizing treatment. This additive, with its unique properties, acts as an effective aluminum brightener, enhancing the surface brightness of the aluminum profiles.

 

The features of LW-38 are quite remarkable. It is a green and environmentally friendly option, as it does not contain nitric acid, nitrate, and nitrite. Its composition ensures that during the chemical polishing of aluminum profiles, it is smokeless, odorless, and does not release toxic gases. This not only benefits the environment but also allows for a comfortable working environment without the need for exhaust purification equipment during processing. Additionally, the LW-38 Chemical Polishing process requires a lower processing temperature and consumes less energy compared to the three acids chemical polishing, making it a more efficient choice.

 

After the anodizing process is completed, when it comes to Cleaning Anodized Aluminum, the prior use of LW-38 can have a positive impact. A smooth and bright surface achieved through the polishing process with LW-38 makes the anodized layer adhere better and is less likely to accumulate dirt and debris. This simplifies the cleaning task and helps in maintaining the appearance of the anodized aluminum. The solution maintenance of LW-38 is relatively straightforward. When the bath solution level drops, one needs to replenish the phosphoric acid, sulphuric acid, and LW-38 according to the appropriate bath make-up ratio (without the need to add aluminum chips during replenishment). It is not necessary to frequently analyze the bath solution, but it is advisable to analyze the content of phosphoric acid, sulphuric acid, water, and aluminum ions every few days or when problems arise and adjust them to the specified parameter range. Overall, LW-38 Two Acids Chemical Polishing Additive, as an Anodizing Agent and aluminum brightener, contributes significantly to the success of the Aluminium Anodizing Process and the subsequent cleaning of anodized aluminum.
