Abstract

The invention discloses a 316 stainless steel cleaning agent, belongs to the field of stainless steel surface cleaning, and particularly relates to the field of stainless steel cleaning agents. The invention aims at solving the problem that an existing stainless steel cleaning agent is not suitable for 316 stainless steel cleaning. The 316 stainless steel cleaning agent is prepared from the chemical components in parts by weight: 16 parts of nitric acid, 10 parts of citric acid, 7 parts of a sodium carbonate and sodium silicate compound, 1.5 parts of alpha-sodium olefin sulfonate, 5 parts of a leveling agent TX-10, 2 parts of sodium alkyl sulfate, 1 part of nekal, 2 parts of corrosion inhibitor and 60 parts of water. The 316 stainless steel cleaning agent does not contain hydrofluoric acid and is suitable for cleaning 316 stainless steel, a nonionic surfactant and an anionic surfactant are compounded, stubborn substances on the surface of the 316 stainless steel can be loosened, nitric acid and citric acid are added to enable the loosened dirt to be rapidly stripped from the surface of the 316 stainless steel, the cleaning effect is good, and the sodium carbonate and sodium silicate compound improves the decontamination capacity; in addition, the citric acid can prolong the service life of the 316 stainless steel cleaning agent and can also play a role in covering the smell.

Description

technical field [0001] 316 stainless steel cleaning agent, the invention belongs to the technical field of stainless steel surface cleaning, in particular to the technical field of stainless steel cleaning agent. Background technique [0002] Stainless steel mainly refers to alloy steel containing more than 12% chromium or more than 16% chromium and more than 8% nickel. They are also general terms for acid-resistant steel and heat-resistant steel, so they can resist corrosion and high-temperature oxidation of certain chemical media. Stainless steel is not absolutely stainless, but it has stronger corrosion resistance to certain media. [0003] 18-8Mo stainless steel (ie 316) was produced in large quantities after the Second World War. It belongs to austenitic stainless steel. Its metallographic structure is single-phase V-phase at high temperature and normal temperature. It is non-magnetic and has good welding and mechanical properties. Susceptibility to corrosion and stre...
