As we all know, dry powder mixers used to produce putty powder, dry powder mortar, insulation mortar and other products basically use ordinary carbon steel. Except for mixing putty paste, stainless steel putty powder mixers are rarely used, even Ant Construction insists on using High-strength carbon steel Q235 material, rust prevention is also an important issue that we have to face. 

How should we perform anti-rust treatment for the new produced sand cement dry powder mixer machine?

  1. First of all, we need to understand the reason of rust on metal parts. The main reason of rusting parts is humidity and oxygen! It is impossible to change the air humidity. The air in the north is drier. The air in the south is more humid, which can easily cause rusting of metal parts. This is one reason why the north area produces more heavy machinery than the south. In addition to changing the air humidity, our commonly used principle of rust prevention is to isolate metal from oxygen. The specific methods for rust prevention of metal parts are as follows:

The sulfur method-Anti-rust treatment for sand cement dry powder mixer machine

  • put sulfide into neutral salt, carbonate, reducing salt and other inorganic substances,  decomposes and diffuses the free sulfur under the action of temperature below 600℃ to form a surface of iron and steel material. It can improve the wear resistance of components!

The quenching method-Anti-rust treatment for sand cement dry powder mixer machine

  • uses an oxygen-acetylene flame to quickly heat the surface layer of the steel  to the quenching temperature, and then quench it, and the surface of the steel will undergo martensite transformation and hardening! There is also a high cheek quenching method, which is place the steel in a high-frequency coil, through the skin effect and proximity effect of high-frequency current, and only the heated surface is quenched and hardened, which can be used to increase resistance!

Vacuum plating (Vacuum evaporation method)-Anti-rust treatment for sand cement dry powder mixer machine

  • Put the metal or compound in a high vacuum of lO'~10"mmHg to be heating This method is mostly used to improve the metallic luster of the product surface and improve the optical properties!


The above are some method for anti-rust treatment, it is not enough only make anti-rust for metal parts in the production process of putty powder mixer.  Ant Construction dry powder mixer machine has always been anti-rust during the production process. All welding gaps must be passivated and then leveled with putty. After the whole machine is polished, make a layer of primer and then anti-rust paint are sprayed. According to the special requirements of customers, some equipment will be used according to needs. Carry out spray treatment to ensure that the equipment will not rust and work stably in different environments.


Well done anti-rust not only can ensure the working quality of the mixer, improve work efficiency, and help extend the use time of the mixer!
