Abstract

The invention discloses an environment-friendly neutral oil and rust removal passivation cleaning agent which is suitable for the field of industrial cleaning. The cleaning agent comprises the following components in percentage by mass: 1%-15% of sodium glycollate; 1%-20% of disodium succinate; 20%-70% of a chelating agent; 5%-30% of organic weak acid; 0.1% to 10% of a surfactant; and 0.1%-10% of a fluorine-containing inorganic compound. The preparation method thereof comprises the following steps: grinding the powdery or granular components to be not less than 30 meshes according to the mass ratio of the components of the cleaning agent, and stirring for 2-3 hours by using a three-dimensional stirrer of which the rotating speed of a main shaft is not less than 20 revolutions per minute to obtain the cleaning agent disclosed by the invention. The cleaning agent has the advantages of no strong acid, no strong alkali, neutral aqueous solution and wastewater, environment friendliness, no toxicity, easiness in decomposition, convenience in transportation, small amount of generated wastewater, small harm to human bodies and metal bodies, no need of heating during use and good passivating effect.

Description

technical field [0001] The invention relates to the field of industrial cleaning, in particular to an environment-friendly neutral cleaning agent for removing oil, rust and passivation. Background technique [0002] All kinds of equipment, pipelines, storage tanks, parts, etc. used in industry are often coated with a layer of protective grease on their surface when they leave the factory. However, the protection of this layer of grease is limited. During transportation, installation, welding Various types of dirt, such as rust, welding slag, rolling scales, etc., will still be produced during the process, and the grease itself will also absorb all kinds of dust and fine particles in the environment. If it is put into use directly, it will inevitably cause various problems, such as polluting raw materials and finished products, affecting the effect of the catalyst, poor paint adhesion, poor heat transfer effect of the heat exchanger, and so on. Therefore, before industrial f...
