Problems solved by technology

In the prior art, chemical raw materials such as dichloromethane, sodium hydroxide, and sodium carbonate are used to remove grease from such seamless steel pipes. This cleaning method needs to be heated to above 100°C, and toxic gas will be discharged at this heating temperature. It has adverse effects on the surrounding environment and the human body, and does not meet the requirements of environmental protection; in addition, the chemical raw materials in this cleaning method will corrode the surface of the seamless steel pipe, resulting in the disappearance of the surface brightness of the seamless steel pipe, and the seamless steel pipe is easy to rust
Therefore, in order to avoid using the above-mentioned unenvironmentally friendly cleaning methods, only manual cleaning methods can be used. The towels are soaked in toluene and gasoline, and the pipes are manually wiped one by one. This is not only time-consuming, laborious and expensive, but also the outer wall of the seamless steel pipe It can be cleaned, and the inner wall of the seamless steel pipe is limited in cleaning
When the customer places the cleaned seamless steel pipe on the lathe to process the product, due to the rotation of the lathe, the grease in the inner cavity of the steel pipe splashes outward, making it difficult to clean

Abstract

The invention relates to a metal deoiling and degreasing environment-friendly cleaning agent and a preparation method thereof. The environment-friendly cleaning agent for removing oil and degreasing metal comprises the following components: 2-4% of sodium hydroxide, 3-7% of edible baking soda, 2-4% of sodium molybdate, 1-3% of sodium carbonate, 1-3% of a penetrant, 2-4% of a disinfectant, 1-3% of hydrogen peroxide, 0.5-1.5% of absolute ethyl alcohol, 2-4% of a corrosion inhibitor and the balance of water. According to the cleaning agent, heating is not needed in the cleaning process, and normal cleaning operation can be carried out from minus 10 DEG C in winter to 40 DEG C in summer; workpieces can be quickly cleaned, and each ton of steel pipes can be averagely cleaned within 56 seconds.

Description

technical field [0001] The invention relates to the technical field of metal cleaning agents, in particular to a metal degreasing and degreasing environment-friendly cleaning agent suitable for cleaning seamless steel pipes and a preparation method thereof. Background technique [0002] In the production process of seamless steel pipes, oil is needed as a lubricant, resulting in the adhesion of grease that is difficult to clean on the inner and outer surfaces of the finished seamless steel pipes. In the prior art, chemical raw materials such as dichloromethane, sodium hydroxide, and sodium carbonate are used to remove grease from such seamless steel pipes. This cleaning method needs to be heated to above 100°C, and toxic gas will be discharged at this heating temperature. It has adverse effects on the surrounding environment and the human body, and does not meet the environmental protection requirements; in addition, the chemical raw materials in this cleaning method will co...
