Description

Technical Field

[0001] This invention belongs to the technical field of stainless steel surface cleaning materials, specifically relating to a method for preparing an environmentally friendly, multifunctional stainless steel cleaning agent. Background Technology

[0002] Stainless steel, as defined in GB / T20878-2007, is steel whose main characteristics are rust resistance and corrosion resistance, with a chromium content of at least 10.5% and a carbon content of no more than 1.2%. Stainless steel generally has certain corrosion resistance and has a wide range of applications and diverse usage environments. It is often used to make everyday household equipment. Especially in the steel industry, materials for machine tools, workpieces, and other processing industries have changed from plastic products to stainless steel products. It is precisely because of the wide range of applications of stainless steel that its application environments are diverse. Under long-term use, a large amount of difficult-to-clean dirt accumulates on the surface of stainless steel. Manual cleaning is time-consuming and laborious, and the cleaning effect is not ideal, which seriously affects the service life of stainless steel materials.

[0003] Stainless steel cleaners can effectively remove most oil stains from the surface of stainless steel materials, and the cleaning process is more time-saving and labor-saving. However, a problem exists that commonly used stainless steel cleaners contain strong acids, strong alkalis, or corrosive chemicals such as chloride ions, which often cause secondary corrosion to the stainless steel materials. Therefore, there is an urgent need to find a cleaner that can effectively remove large amounts of dirt from the surface of stainless steel materials without causing secondary corrosion.
