Problems solved by technology

[0003] Since aluminum is an active metal, aluminum products are easily oxidized or moldy under certain temperature and humidity conditions. The existing cleaning agents, in order to have a good cleaning effect, generally use alkaline cleaning agents and acid cleaning agents. After cleaning the aluminum material with an acidic cleaning agent, the aluminum material is easy to change color, and white spots are easy to appear on the surface of the aluminum material. After cleaning the aluminum material with an acidic cleaning agent, white spots will appear, and mildew spots will appear in a humid climate.
Moreover, aluminum scraps will be produced during the stretching process, and the existence of aluminum scraps limits the use of aluminum

Description

technical field [0001] The invention relates to the field of chemical cleaning agents, more specifically, the invention relates to a cleaning agent for 3003 aluminum materials. Background technique [0002] 3003 aluminum alloy is an Al-Mn alloy, the main components are aluminum, silicon, copper, zinc, manganese, iron, and it is the most widely used antirust aluminum. The strength of this alloy is slightly higher than that of industrial pure aluminum, and it cannot be heat treated. Strengthening, so the cold working method is used to improve its mechanical properties: high plasticity in the annealed state, good plasticity in semi-cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability, and poor machinability . 3003 aluminum alloy is mainly used for low-load parts that require high plasticity and good weldability, and work in liquid or gaseous media, such as fuel tanks, gasoline or lubricating oil conduits, various liquid contai...
