Trivalent chromium (immersion) - aluminum floor

The trivalent chromium (immersion) process used in aluminum flooring is a method of surface treatment for aluminum flooring. The following is an introduction to the principles, advantages, process and precautions:

principle

The trivalent chromium immersion treatment uses a solution containing trivalent chromium ions to react chemically with the surface of the aluminum floor to form a chromate conversion film on the surface of the aluminum floor. This conversion film can improve the corrosion resistance, wear resistance and adhesion of the aluminum floor, and also play a certain decorative role.

advantage

Good corrosion resistance: The trivalent chromium conversion film can effectively isolate the aluminum floor from moisture, oxygen and other corrosive substances in the external environment, thereby slowing down the corrosion rate of the aluminum floor and extending its service life.

Better environmental performance: Compared with the traditional hexavalent chromium treatment process, the trivalent chromium compound used in the trivalent chromium immersion process is less toxic and less harmful to the environment and human health. While meeting environmental protection requirements, it also reduces the cost and pressure of enterprises in environmental protection treatment.

Better decorative effect: After being soaked in trivalent chromium, a uniform and delicate conversion film can be formed on the surface of the aluminum floor. The color can be adjusted as needed. It is usually silvery white or light yellow. It has a good decorative effect and can meet the requirements of different users for the appearance of aluminum floors.
