What is used to clean the copper surface? Copper is a very common metal element in life, and it is easy to oxidize when exposed to air, so you should pay great attention to it when cleaning, so as to achieve good results. Let's share with you what to clean the copper surface. Let's take a look.

What is used to clean the copper surface? 1 What is used to clean the copper surface?

The environment-friendly copper cleaning agent consists of effective components such as surfactant, cleaning aid, corrosion inhibitor and penetrant. It is a water-based environment-friendly cleaning agent specially used for cleaning dirt on copper surface. After cleaning, the original color of copper can be restored, and then the effect of no oil and no scale can be achieved.

Advantages of copper environmental cleaning agent

1, safe and corrosion-free. Copper environmental cleaning agent has no corrosion to copper and alloy, and is safe and reliable.

2. Specialty. Copper environmental cleaning agent is specially used for copper and copper alloy, which can effectively clean the dirt on the surface.

3. Good stability. The solution of copper environmental cleaning agent is stable, non-decomposed, non-volatile and reusable.

4. This product is environmentally friendly. The formula of copper environmental cleaning agent does not contain harmful components such as nitrite, chromate and heavy metals.

5, the cleaning speed is fast. Copper environmental cleaning agent can quickly clean the dirt such as oil and grease on the surface of copper parts, and the cleaning effect is good.

What is used to clean the copper surface? What are the important alloys of copper?

Red copper: refers to pure copper, the main varieties are oxygen-free copper, red copper, phosphorus deoxidized copper and silver copper.

Brass: refers to the alloy based on copper and zinc, which can be subdivided into simple brass and complex brass. The complex brass is named nickel brass and silicon brass with the third component.

Bronze: refers to copper-based alloys other than copper, nickel and copper-zinc alloys. The main varieties are tin bronze, aluminum bronze and special bronze (also known as high copper alloy).

White copper refers to copper-nickel alloy.

Causes of surface oxidation of red copper in production

1, surface pollution: The following factors are easy to cause copper surface pollution and oxidation discoloration:

(1) The surface of copper is wetted by (rainwater);

(2) Residual emulsion or cleaning solution splashes on the copper surface.

(3) Occasionally, other dirt pollutes the copper surface (such as adding more drops of crown block lubricating oil). )

(4) Contact with copper by hand, and package E is corrosive.

2. Wet weather: The weather in the south of China is wet, and there is oxidation blackening in the production process.

3. Improper control of process parameters: insufficient exhaust during annealing, unclean atmosphere in the furnace and high discharge temperature will lead to more unqualified products with discoloration and blackening.

4. Failure of annealing equipment: When copper is annealed, the lower the oxygen potential of the protective atmosphere in the furnace, the better. It is required that the oxygen content in the protective atmosphere in the furnace is only 10-6, preferably slightly reduced. However, the continuous roller hearth annealing furnace used in our factory is relatively backward. In actual production (especially bell jar furnace and shaft furnace), oxidation discoloration caused by leakage of furnace lining, pipeline and valve accounts for a certain proportion.

Importance of cleaning oil stain on copper surface

After heat treatment, the surface of red copper parts will produce oxide scale, which will have a negative impact on the subsequent processing of parts, and the surface quality and hardness of parts will decrease, which will also reduce the qualified rate of products.

Selecting the product characteristics of copper cleaning agent;

1, the dissolved oxide has good performance and is easy to wash, which effectively protects the surface of the cleaned material from erosion.

2, operating at normal temperature, and the cleaned copper piece forms a mirror effect,

3, does not contain heavy metals and harmful substances, is completely biodegradable, and belongs to environmental protection products.
