Rust inhibitor AF40

Product features:

1. Water-based environmental protection products, free of sodium nitrite and other harmful substances, friendly to human body and environment;

2. Good spreading performance, can quickly form an effective anti-rust layer on the surface of the product, and the anti-rust film is dry and oil-free;

3. Applicable to cast iron, carbon steel, Ru iron boron magnet, die steel and other easy to rust iron materials;

4. For long-term rust prevention of products, it is the most ideal water-based product to replace rust prevention oil;

5. Anti-rust time more than 8 months.

How to use:

Oil removal "oil removal" rinsing "rinsing" rust prevention "drying

Note: If flash rust appears (rust begins to appear in the water bleaching link), 1-2% of AF40 water-based rust prevention agent can be added to the bleaching tank.

Scope of application:

Long-acting water-based anti-rust agent AF40 is used in steel parts, metal processing parts, castings, forgings, cylinder liner, crankshaft, bearing, pump machinery manufacturing and maintenance of ferrous metal, auto and motorcycle parts and many other industries in the medium and long term anti-rust, semi-finished rust and finished rust.

First, product principle

The long-acting water-based anti-rust agent AF40 has high spreading performance, and relies on the surfactant molecules with anti-rust function to rapidly combine with metal molecules to form protection, so as to avoid the oxidation reaction of metal in direct contact with air, so as to achieve the purpose of anti-rust. There is no need to clean the product before entering the next process after treatment, which has no impact on the product size and surface finish, and does not affect the subsequent welding, paste and other properties.

Second, product characteristics

The rust prevention period is different due to the difference in environmental temperature, humidity and corrosive ingredients, usually up to more than 8 months, and the rust-prone materials of cast iron and carbon steel are more than 6 months.

3. Scope of application

1. It is used for oil-free short-term rust prevention (inter-process rust prevention) of rust-prone metal workpieces such as cast iron and steel parts. It is suitable for black metal materials in the repair process of various machinery and equipment of industrial production enterprises, and medium and long-term rust prevention treatment of parts.   2. Used for plating, phosphating workpiece passivation anti-rust treatment, can greatly improve the corrosion resistance of electroplating, phosphating film.

5. Preparation and use conditions of anti-rust working fluid

ratio

Long-acting water-based anti-rust agent AF40: water mixing ratio of about 1:5, rust prevention between processes 1:20-50 (depending on rust prevention requirements)

Long-term rust prevention period: 8-12 months

Temperature: normal temperature - 60℃    (Generally used at room temperature, in order to make the workpiece dry quickly after rust prevention, the anti-rust liquid can be heated to 40-60℃)

Soaking time: 2-3 minutes

Six, precautions

1. Under normal circumstances, the workpiece immersed in the working liquid for 2 to 3 minutes can achieve satisfactory anti-rust effect, if the use of spray (brush) coating method to deal with large and complex workpiece, should ensure that the liquid fully wet all corners of the workpiece, uneven treatment will seriously affect the anti-rust effect.

2. Before rust prevention treatment, it is necessary to ensure that the surface of the workpiece is free of oil pollutants and rust, no granular attachments, and the higher the surface finish, the better the rust prevention effect. Do not bring acidic water into the anti-rust liquid, otherwise the anti-rust liquid will fail, and the anti-rust effect is poor. The workpiece after rust removal with acid should be rinsed at least two times with flowing water to ensure that the surface of the workpiece is neutral.  

3. Under normal circumstances, the concentration of anti-rust working liquid will not be reduced, but the amount should be reduced, and the stock liquid and water should be added proportionally. When the rust inhibitor is brought into the tap water or cleaning agent residue, the pollution cannot effectively prevent rust. , you need to re-slot. It is recommended that the slot opening time be the same as that of the cleaning agent.

4. After the anti-rust liquid treatment of the workpiece, it is best to use a compressed air spray gun to blow off the surface and each dead corner of the residual water, and then dry, if the conditions are best to dry, the dried workpiece should be placed in a dry packing box, or wood as the basis of the ground.  

5. Before preparing the working liquid, shake the bucket several times before pouring out the original liquid.

Vii. Packaging and storage

25KG/50KG/ barrel, sealed storage in cool and ventilated warehouse, shelf life of two years.
