Plating is a very common phenomenon in various fields, products and equipment. The essence of plating is nothing more than to protect the product well, prevent damage, and prevent rust. However, in the field of fire pumps, even if the fire pump is coated, rust may occur. Why are there rust spots on the surface of the fire pump coating ? What causes rust spots on the coating of fire pumps ? Let ’s talk to everyone.
Reason 1: Insufficient plating time, it can be said that the process is not precise enough;
Cause two: The ventilation of the fire pump's environment is not good, especially in a humid, dark environment or a pump room with a large temperature difference, which can easily cause rust spots on the coating surface of the fire pump.
Cause three: The collision of the fire pump during transportation causes the coating surface to be damaged. During use, it is naturally easier to oxidize and rust spots appear;
Reason 4: The coating materials are not good enough. In order to control costs, some companies will have different choices of materials used in fire pumps. There are many coating materials, mainly divided into single metals and alloys, such as zinc, cadmium, gold or brass, bronze, steel, stainless steel, etc. Generally good fire pumps, the coating is mostly stainless steel, because the corrosion resistance of stainless steel is relatively Said stronger.
Reason 5: The daily dirt on the fire pump does not pay attention to cleaning, which is also one of the reasons that cause rust spots on the coating surface.
For fire pumps, even if the surface is coated, rust will appear. The rust spots on the surface of the coating appear early, and the fire pump will rust faster. The surface of the fire pump's coating is rusty. In addition to material problems, it is also affected by solar radiation, ambient temperature, oxygen concentration, humidity, or possible pollutants (such as acid rain, ozone) under the environment.
