Reasons for the Rusting of Steel Reinforcing Bar Coupler
The raw material of the steel reinforcing bar coupler is 45# carbon structural steel. It is determines that if the steel reinforcing bar scoupler comes into contact with water, it will rust within a few minutes. However, rusted steel reinforcing bar couplers will seriously affect the quality of the project. Therefore, preventing rust in steel reinforcing bar couplers is an important process in the production of steel reinforcing bar couplers. There are five main reasons for the rusting of steel reinforcing bar couplers: 1. Poor quality of cutting fluid During the process in the production of steel reinforcing bar couplers, cutting fluid is used. The fluid is a water-soluble oil with certain rust removal and rust prevention functions. If the quality of the cutting fluid is poor and the concentration is low, the steel reinforcing bar sleeves should not be stored for a long time, as they are prone to rust. 2. Poor quality of packaging bags The packaging bag for steel reinforc...
