Rust is a compound. When iron is in a moist state for a long time, it will react with oxygen - rusted iron will rust if left for a long time. Iron is prone to rusting, not only due to its active chemical properties, but also closely related to external conditions. Moisture is one of the substances that makes iron prone to rusting. Iron will rust if left for a long time. Iron is prone to rusting, not only due to its active chemical properties, but also closely related to external conditions. Moisture is one of the substances that makes iron prone to rusting. However, water alone will not cause iron to rust. Only when oxygen in the air dissolves in water and reacts with iron in a water environment, will a substance called iron oxide be formed, which is called rust.

So which parts of the belt filter need regular rust prevention?

Under normal circumstances, the working environment of belt filters is relatively humid, which can easily cause rusting problems, leading to a decrease in the performance of belt filters, and in severe cases, even causing some components to malfunction. The chain on the active pull plate is the most commonly rusted component of the belt filter, so we need to regularly apply an appropriate amount of lubricating oil. In addition, the screw rod of the hydraulic press in the belt filter is also a part that is prone to rusting. I believe everyone knows that during the operation of the belt filter, the screw rod inside the hydraulic press will continuously move, which will cause some iron atoms to lose electrons and be in an unstable state. Although this phenomenon does not produce adverse reactions during operation, when the belt filter stops, the unstable iron atoms will react with water molecules and oxygen atoms in the air, accelerating the rusting time of the metal. So after the equipment is stopped, it is necessary to add more lubricating oil to the area to prevent contact with the air.

If rust has already rusted and needs to be removed, various tools can be used to shovel it off, or it can be dissolved in an acidic solution. After removing rust, it is necessary to treat the surface of the iron, apply a layer of lead paste, and then apply paint; Or plated with other metals that are not easily rusted. A better way is to add some other metals to iron to make a stainless alloy. The stainless steel we are familiar with is an alloy made by adding a little nickel and chromium to steel.
