The most important factor affecting the price of aluminum coils is whether it is easy to remove oil and dust when processing aluminum products. Today, we'll take a closer look at how to remove oil and ash from aluminum products.
At present, there are various oil and ash methods in the aluminum product processing market: alkali method, acid-base method; we all know that caustic soda is used to undergo alkali etching, polishing and dust removal in 15--20 nitric acid solution, but some processing plants Since there is no good method to grasp, it is often due to the deposition of aluminum oxide and the concentration and trouble of nitric acid. In addition, caustic soda and nitrate are both dangerous goods. During use, the smell of nitrate is comparable to that of caustic soda. Large ones are often unbearable for workers to use, etc. Some processed plants use solvents to remove oil, which are volatile and have poor oil removal effect. Especially the current extrusion and stretching oil has a complex composition and cannot be removed by some solvent degreasing agents.
1. Soaking, oil removal and dust removal:
1. Add a small amount of tap water before use, and then immerse the aluminum product in the pool; (Adjust the ash remover)
2. Add aluminum products to remove oil and heat automatically in 5-10 seconds.
3. After removing the oil for 2 to 3 minutes, put it into tap water and wash it;
4. Dust removal with ash remover (no more than 30 seconds);
5. Water cleaning ---- drying (drying) or oxidation.
In this process, when the heating temperature of the oil is high, the oil degreaser can be appropriately diluted.
two. Spray to remove oil and dust:
1. Add appropriate amounts of water to dilute the degreasing agent and degreasing agent respectively.
2. Adjust the angle of the nozzle.
3. Ensure the spraying time (not less than 30 seconds);
4. Ensure there is circulating water for flushing;
Products that do not dissipate enough heat when stretched and extruded require extended oil and dust removal times.
There is basically no precipitation after use of the product, and it can be completely consumed with less emissions and less pollution. After the oil is removed, the surface of the product is not damaged and there is no corrosion on the surface. After the dust is removed, the surface of the product is white and has a protective effect. No corrosion (no oxidation) within 30 days.
