Embodiment

[0030] Take 25% of sodium hydroxide, 3% of sodium hypochlorite, 5% of surfactant, 0.1% of chelating auxiliary agent, 3% of antibacterial agent and the rest of deionized water to prepare a degreasing cleaning agent by mass.

[0031] This degreasing cleaning agent is used for the degreasing treatment (moving speed is 270 m / min) of common carbon steel plate of certain cold rolling factory and the degreasing treatment (traveling speed is 180 m / min) of stainless steel plate of certain stainless steel factory, and its flow process is: Alkaline spray cleaning (lye concentration 1.0% ~ 2.5%, pressure 3 ~ 4 atm) - Spray scrub again (lye concentration 1.0% ~ 2.5%, pressure 3 ~ 4 atm) - ion exchange water washing (pressure 3 ~ 4 atm) - rinse with pure water (pressure 3 ~ 4 atm) - dry. The degreasing and washing temperature of the former is 55 ~ 65°C, and the temperature of the latter is 80 ~ 85°C, both of which have achieved satisfactory results;

[0032] In short, this product is used ...

Abstract

The invention discloses a low-temperature degreasing cleaning agent, comprising, by mass, 10-30% of chemically pure sodium hydroxide, 2-5% of chemically pure sodium hypochlorite, 5% of a chemically pure surfactant, 0.1% of a chemically pure chelating auxiliary agent, 1-3% of a chemically pure antibacterial agent, and the balance being chemically pure deionized water. The surfactant comprises at least one of an NP series surfactant, fatty acid methyl ester (FMEE), a heterogeneous tridecane alcohol ethoxylated compound and an RF series surfactant; the chelating auxiliary agent comprises ethylenediamine tetraacetic acid (EDTA); and the surfactant comprises an RF-25-1 surfactant; and the antibacterial agent is triclosan. With the above way, the low-temperature degreasing cleaning agent provided by the invention can be used at a low temperature lower than or equal to 60 DEG C, contains low bubble content or no bubble, can be used for cleaning rotating steel belts, can be used for cleaning rotating metal products with a contact time longer than 20 seconds at a low temperature environment, and has antibacterial property as well as environmental protection property.

Description

technical field [0001] The invention relates to the field of cleaning agents, in particular to a low-temperature degreasing cleaning agent. Background technique [0002] In the strip steel surface coating and coating processing production line, the cleaning and degreasing of the strip steel surface is an important link that affects product quality. Practice has proved that if the degreasing of the surface of the strip is not complete, the paint or coating will be difficult to fully spread and adhere to the substrate, and in severe cases, the coating will peel and fall off. Strip cleaning and degreasing is to use the active ingredients in the degreasing agent to reduce the adhesion of surface oil, and through saponification, dispersion, and emulsification, the oil is converted into soap or in an emulsified state, and detached from the steel strip substrate. At the same time, the chelating agent in the degreasing agent interacts with the metal ion components in the oil to for...
