Hazards of rust remover

We know that some metals often rust outdoors or in the open air. This will affect the appearance of the metal, cause corrosion, affect the service life of the metal, and often easily lead to the scrapping of some metal materials. Therefore, rust removers are often used in this situation. Generally speaking, rust removers are not particularly harmful to people, as long as some protective measures are taken.

Rust remover hazards

Maybe. Some protective measures can be used, such as masks and other labor protection supplies. What kind of rust remover are you using? What product do you want to remove rust? The specific details should be based on the actual ingredients of the rust remover and the manufacturer. Generally speaking, they are acidic preparations and will not cause harm to the body. After all, this thing is like detergent. If it is poisonous, who would dare to use it among the people?

Metal rust remover advantages:

1. It has a wide range of applications and can restore the original color of metals.

2. Rust, pollutants and oxides can be removed in a short time.

3. No damage to the substrate.

4. Safe and environmentally friendly, avoiding environmental pollution.

5. When used at room temperature, the rust removal effect is more obvious compared with other rust removal products on the market.

6. It can be applied by dipping, brushing, spraying and other methods, and the operation is simple.

7. It will not affect substrates such as plastics, rubber products, and paints.

8. Non-flammable, non-explosive, and no peculiar smell.

9. Does not contain heavy metal components; has stable functions, quick rust removal and obvious effects.

Rust removal mechanism

After the steel is soaked in the rust inhibitor, the rust remover penetrates into the surface of the steel along the cracks of the rust layer and the impurity layer, dissolving and peeling off the rust layer and the impurity layer. The various raw materials in the rust remover are adsorbed on the steel surface, rust layer and impurity layer, forming a diffuse double electrical layer at the solid/liquid interface. Since the rust layer and the steel surface have the same charge, they repel each other, causing the rust layer, impurities and oxide scale to fall off the steel surface.

The hydrochloric acid in the rust remover can clean the surface of steel, improve the pickling effect, and increase the pickling speed. When the rust remover is circulated, an activator composed of citric acid and hydrochloric acid can be added to further increase the rust removal speed and eliminate odor. Citric acid can neutralize iron ions. Hydrochloric acid increases the energy of the acid.
