How to use:
Oil removal "oil removal" rinsing "rinsing" rust prevention "drying
Note: In case of flash rust (rust begins to appear in the water bleaching link), 1-2% of water-based anti-rust agent AF41 can be added to the bleaching tank.
Scope of application:
Environmental protection waterborne anti-rust agent AF41 is used in steel parts, metal workpiece, castings, forgings, cylinder liner, crankshaft, bearing, pump machinery manufacturing and maintenance of ferrous metal, auto and motorcycle parts and many other industries between the process of rust prevention, semi-finished products and finished products.
First, product principle
The water-based anti-rust agent AF41 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 30 days, and cast iron carbon steel is easy to rust for 15 days.
3. Scope of application
1. Water-based anti-rust agent AF41 is used for oil-free short-term anti-rust (inter-process anti-rust) 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 short and medium-term anti-rust treatment of parts.
2. Water-based anti-rust agent AF41 is used for plating and phosphating workpiece passivation anti-rust treatment, which can greatly improve the corrosion resistance of electroplating and phosphating film.
Preparation and use conditions of anti-rust working fluid
Ratio (dilution weight ratio of raw liquid to water) : 2-5% concentration
That is: 1 part of this product: 20-50 parts of water (depending on rust prevention requirements)
Rust prevention period: 15-60 days
Temperature: normal temperature -50℃ (generally normal temperature can be used, in order to make the workpiece dry quickly after rust, rust liquid can be heated to 40-50℃)
Soaking time: 2-3 minutes
5. 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 can not effectively prevent rust, it needs to be re-slotted. 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.
6. Packaging and storage
25KG/50KG drum, sealed storage in a cool and ventilated warehouse, shelf life of two years.
