Problems solved by technology

Because phosphate will directly promote the proliferation of microorganisms in water, excessive consumption of oxygen in water, the discharge and accumulation of phosphate will pollute the water quality of rivers, lakes and seas, affect the survival of aquatic organisms and animals, and destroy the ecological balance. Discharge of phosphorus waste is already limited by environmental regulations

Embodiment Construction

[0021] The embodiment of the present invention is an aqueous solution prepared by mixing Agent A and Agent B. The concentration of Agent A is 3-5%, and the concentration of Agent B is 1-3%, which maintains the solubility and transparency of the water-based degreasing agent.

[0022] The raw materials and mass percentages of the A agent are: 2-4% sodium carbonate, 2-4% sodium metasilicate pentahydrate, 2-4% sodium citrate, 3-7% sodium nitrite, 0.5-4% pull open powder 1%, triethanolamine 3~5%, defoamer 0.1~0.3% and tap water balance;

[0023] The raw materials and mass percentages of the B agent are: potassium hydroxide 0.5-1.8%, active agent QYL-20 4-6%, active agent AEO-9 1.5-3%, penetrant JFC 0.5-1%, Taigu oil 0.8~1.5%, defoamer 0.4~0.8% and tap water balance.

[0024] Specific manufacturing method:

[0025] Described A agent carries out as follows:

[0026] a. Add measured tap water into the reaction kettle, heat up to 40-50°C, and start the agitator;

[0027] b. Slowly ...

Description

technical field [0001] The invention relates to a metal workpiece surface degreasing agent and a manufacturing method thereof, in particular to a phosphorus-free and environment-friendly water-based degreasing agent which has good degreasing effect, is easy to clean and can meet the requirements of subsequent processes, and a manufacturing method thereof. Background technique [0002] During the manufacture and use of metal workpieces, due to mechanical processing, rust prevention, loading, storage and transportation, etc., the surface of metal workpieces is often in contact with various oils based on mineral oils or animal and vegetable oils and added with various organic additives or inorganic substances. (oil stain). Therefore, in the surface treatment process of metal workpieces, the first important process to be implemented is the need for these oils (degreasing, degreasing), otherwise it is difficult to ensure the quality of the conversion film in the subsequent proces...
