Environment-friendly ash removal agent

Abstract

The invention belongs to the technical field of chemical polishing of aluminum alloy, and specifically discloses an environment-friendly ash removal agent. The environment-friendly ash removal agent is prepared from the following components in parts by weight: 1% to 2% of sulfuric acid, 20% to 25% of oxidizing agent, surfactant, polycarboxylic acid compounds and the balance of water. Compared withthe prior art, the environment-friendly ash removal agent has the advantages that a sulfuric acid and hydrogen peroxide system is adopted, ammonia nitrogen is not contained, the ash removal effect isquick, the ash removal operation takes more than one minute on the market, but the ash removal operation can be completed by the product within 25 seconds to 30 seconds, the ash removal effect is good, the speed is high, the ammonia nitrogen is not contained, so that environmental pollution is reduced, the effects of environmental friendliness, safety, high use efficiency and low cost are achieved, the surfactant prepared from sodium dodecyl benzene sulfonate is added and is used as a stabilizing agent of the oxidizing agent, the polycarboxylic acid compounds are combined so as to prevent thesurface of an aluminum product from being corroded, the product is used for removing ash only and cannot corrode, and the use safety is high.

Description

Technical field

[0001] The invention belongs to the technical field of aluminum alloy chemical polishing, and specifically relates to an environmentally friendly ash remover. Background technique

[0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. The rapid development of industrial economy has increased the demand for aluminum alloy welded structural parts. The increase in weldability of aluminum alloys also deepened the research on the weldability of aluminum alloys. Aluminum alloys usually use alloying elements such as copper, zinc, manganese, silicon, and magnesium. They were invented by the Germans in the early 20th century, which greatly helped the development of aircraft. The composition of aluminum alloy is listed as a national secret. Compared with ordinary carbon steel, it has lighter and corrosion resi...
