Problems solved by technology

The disadvantage of this hot-dip galvanizing process is: when dipping and helping the plating solvent (activation treatment), the exhaust gas is seriously discharged, which affects the normal life of nearby residents and does not meet environmental protection requirements.

Abstract

The invention discloses a matching solvent for a hot galvanizing process of a road component. The matching solvent comprises components in percentage by mass as follows: 30%-40% of ammonium chloride and 60-70% of zinc chloride. With the adoption of the matching solvent, less exhaust gas is discharged, normal life of neighboring residents is not affected, and environmental protection requirements are met.

Description

technical field [0001] The invention relates to a hot-dip galvanizing process, in particular to a proportioning solvent used in the hot-dip galvanizing process of road components. Background technique [0002] Hot-dip galvanizing, also known as hot-dip galvanizing, is a method in which steel components are immersed in molten zinc to obtain a metal coating. With the rapid development of high-voltage power transmission, transportation, and communication, the protection requirements for steel parts are getting higher and higher, and the demand for hot-dip galvanizing is also increasing. [0003] The traditional hot-dip galvanizing process is: workpiece→degreasing→water washing→pickling→water washing→dip in plating solvent→drying preheating→hot-dip galvanizing→finishing→cooling→rinsing→drying→inspection. Among them, degreasing can use chemical degreasing or water-based metal degreasing cleaning agent to degrease, until the workpiece is completely soaked in water. For pickling...
