Solution: How to improve the thickness uniformity of galvanized layer?
Dec 09,2024
1. optimization of galvanizing process
Control the composition of zinc plating solution
Strictly control the ratio of galvanizing bath to ensure that the zinc content and additive ratio meet the requirements.
Regularly check the content of zinc ions, sodium hydroxide and other key components in the plating solution, and adjust them as needed.
Adjust galvanizing temperature and time
Ensure that the galvanizing temperature and time are within the appropriate range to obtain a better galvanizing effect.
Avoid uneven coating thickness caused by too high or too low galvanizing temperature and too long or too short galvanizing time.
Stirring and circulation during galvanizing
Through stirring and circulation, the galvanizing solution is evenly distributed to reduce the local concentration difference.
Regularly check the working status of the mixing system and circulation system to ensure their normal operation.
2. strengthening steel surface pretreatment
Remove impurities from the steel surface
Use reliable quality cleaning agent, pickling liquid, etc., to remove the oxide skin, oil, rust and other impurities on the steel surface.
Operate in strict accordance with the use method to ensure the cleaning effect.
Control the roughness of the steel surface
Choose excellent steel with low impurities such as sulfur and phosphorus.
Control the roughness of the steel surface by grinding, polishing and other methods to ensure its consistency.
3. improve the quality of galvanizing equipment and facilities
Choose high quality galvanizing equipment
Choose galvanizing equipment with stable performance and reliable quality, such as galvanizing tank, heating system, stirring system, etc.
Regularly maintain and maintain the galvanizing equipment to ensure its normal operation.
Check and replace old parts
Regularly check the operation status of galvanizing equipment, find and replace old parts in time.
Ensure the accuracy and stability of the galvanizing equipment to reduce errors in the galvanizing process.
4. to avoid damage during machining
Pay attention to the protective coating
During the processing of galvanized square pipes, such as cutting, punching, bending, etc., pay attention to protect the coating to avoid damage to the coating.
Use suitable tools and methods for processing to reduce vibration and friction during processing.
Take measures to repair plating and repair
For galvanized square pipes with uneven coating, they can be treated by plating or repair.
Make sure that the thickness and uniformity of the plated layer meet the requirements.
5. other measures
Optimize workpiece design
In the design of the workpiece, the influence of its shape and size on the thickness uniformity of the galvanized layer is considered.
Try to avoid workpieces with complex shapes or oversized sizes to reduce the difficulty and error in the galvanizing process.
Strengthen quality control
Establish a sound quality monitoring system to monitor all aspects of the galvanizing process in real time.
Regular sampling inspection shall be carried out on the galvanized layer to ensure that the thickness uniformity meets the relevant standards and requirements.
In summary, to improve the uniformity of the thickness of the galvanized layer, it is necessary to optimize the galvanizing process, strengthen the surface pretreatment of steel, improve the quality of galvanizing equipment and facilities, avoid damage during processing, and strengthen quality control. Through the comprehensive application of these measures, the thickness uniformity of the galvanized layer can be significantly improved, thereby improving the overall performance and service life of the workpiece.
