Problems solved by technology

Since the chromium salt cleaning agent is only corrosive and oxidizing, it cannot react with the impurities attached to the hanger, so sodium hydroxide pre-soaking is often required; this prolongs the cleaning process and reduces the cleaning efficiency

Abstract

The invention discloses an anode production line hanger detergent. The anode production line hanger detergent is prepared from a softening agent, hydrogen peroxide, a disintegration inhibitor, hydrofluoric acid and water. The detergent is fewer in high-toxicity and high-corrosion raw material, and is nontoxic, environmentally friendly and long in service life. Correspondingly, the invention also discloses a method for cleaning an anode production line hanger by using the detergent. The cleaning efficiency is high, the cleaning speed is high, and the operation is simple.

Description

technical field [0001] The invention relates to the field of cleaning agents, in particular to a cleaning agent for hangers of an anode production line, a preparation method and a cleaning method thereof. Background technique [0002] The hanger is used as a conductive carrier for the vertical anodizing production line, but as the production progresses, the acid-base and various impurities (such as sodium sulfate, aluminum hydroxide, aluminum sulfate, etc.) in the production line are easy to adhere to the hanger. Affect its electrical conductivity, so the hanger must be cleaned. The existing technical means often use acidic cleaning agents containing hexavalent chromium to clean the hangers. Although this cleaning agent can efficiently clean the hangers of the anodizing production line, with the development of society, the environmental protection requirements of enterprises are becoming more and more serious. The higher the concentration, because hexavalent chromium is an ...
