Non-phosphorus environment-friendly powdery degreasing agent and manufacturing method thereof

Abstract

The invention discloses a non-phosphorus environment-friendly powdery degreasing agent with good degreasing effect, easy cleaning and capability of meeting the requirements of back end of line process and a manufacturing method thereof, and the degreasing agent comprises the following raw materials: potassium hydroxide, sodium carbonate, sodium silicate pentahydrate, phosphate free builder, sodium citrate, sodium nitrite, activating agent QYL-10F, activating agent AEO-9, penetrating agent JFC and defoaming agent. The manufacturing method is carried out according to the following steps: starting a coulter stirring machine, and adjusting the rotational speed to be 30-40 turns / minute; sequentially adding the weighed sodium carbonate, sodium silicate pentahydrate, sodium citrate, phosphate free builder, sodium nitrite and potassium hydroxide into the stirring machine, wherein the uniform stirring needs to be carried out when adding every raw material, and the stirring needs to be carried out for at least 20 minutes; adding the weighted defoaming agent in the stirring machine, and stirring uniformly; further sequentially adding the weighted activating agent QYL-10F, activating agent AEO-9 and penetrating agent JFC into the stirring machine, wherein the uniform stirring needs to be carried out when adding every raw material, and the stirring needs to be carried out for at least 20 minutes.

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 powder 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 process, a...

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
