In mine construction, everyone knows that Extension Drilling Tools will have many headaches that we all have when drilling. Not only is it easy to break, but the surface of Extension Drilling Tools is also easy to rust. Once Extension Drilling Tools is rusty Its appearance indicates that its useful life is greatly reduced. Therefore, when using Extension Drilling Tools, workers in mines or coal mines should not only pay attention to the correct method of use, but also take care of maintenance and anti-rust measures after construction.

　　Some Extension Drilling Tools manufacturers use some helpers such as rust removers to help remove the rust. Although this method is relatively quick, it requires a certain amount of money. The mine personnel can choose the method that suits them according to their needs. The selection of appropriate derusting chemicals and the use of geological drill pipes is mainly based on the type of geological drill pipe, chemical composition, surface condition, dimensional accuracy and surface quality of the parts.

Reaming Bits are generally made of steel or metal, which are easy to rust. Our Reaming Bit manufacturer’s technicians have learned that it is good to dissolve rust through the principle of chemical reaction. Pickling method that dissolves the rust products on the surface.
　　The principle is the dissolution of metals by acid, and the mechanical action of hydrogen generated in chemical reactions to fall off the rust layer. Commonly used acids include hydrochloric acid, sulfuric acid, phosphoric acid and so on. Due to the different metals in mining machinery and equipment, the chemicals used to dissolve rust products are also different. Different Reaming Bits have different materials, and the difficulty of removing rust will be difficult and easy. If one method cannot completely remove the rust, we can use other methods to make our Reaming Bit return. To the original look completely new.
