Project Background：
A core subsidiary of a leading domestic steel group is renowned in the domestic bright steel sheet market for its exceptional shape and thickness accuracy control, as well as impeccable surface quality. Its products are widely used in various fields, including automotive, high-end home appliances, and kitchenware.
Challenge：
The company has been using a phosphorus-containing degreaser from a foreign brand in its bright sheet degreasing process. However, with the rapid development of new energy vehicles and the accelerating pace of domestic substitution, the company is now facing the following challenges:
- Improving the surface quality of the products
- Accelerating production efficiency while reducing energy consumption
- Meeting green and environmental protection requirements
Solution:
In response to these challenges, KERUN’s R&D team custom-developed the KR-RSD series of phosphorus-free degreasers, meeting the high standards required for bright sheet cleaning. This solution successfully reduced overall costs and degreasing temperatures, achieving the triple goals of energy saving, quality improvement, and environmental protection.
Benefit：
After thorough testing and validation, the KR-RSD series demonstrated excellent performance on the production line, helping the client advance towards enhanced quality, improved efficiency, reduced energy consumption, and green, sustainable development.
1. Great performance
Strong oil removal capabilities, fast degreasing speed, and excellent de-graying effects.
- Oil removal effectiveness is verified through a dyne test；
- After wiping with qualitative filter paper 30 times, the filter paper shows no significant color difference or black residue.
Operating temperature is low (50-55℃）， Excellent Defoaming Property.
2. Energy Save
After implementing the KR-RSD series, the alkaline wash stage temperature setting was reduced by 30%, and the corresponding steam valve opening of the heat exchanger was decreased by 50%. Overall calculations showed that the company’s annual comprehensive usage costs were reduced by more than 20%.
3. Safty&Eco-friendly
The degreaser is free of phosphates, silicates, borates, and heavy metal salts, all of which are harmful to the environment, thereby reducing environmental pollution.
