How Jinhaeng RSI Works
How Jinhaeng RSI Removes Rust and Prevents Leaks
-
- A corrosion prevention method in which a more reactive metal is used to protect another metal. Zinc (Zn), being more electrochemically active than iron (Fe), oxidizes first and prevents iron from corroding.
- In Jinhaeng RSI, zinc (Zn) has a higher ionization tendency than iron (Fe), so zinc ionizes first and protects steel while preventing corrosion.
-
- The anti-corrosion electrons generated by Jinhaeng RSI react with rust (Fe₂O₃), converting it into magnetite (Fe₃O₄).
- Magnetite has a stable and dense structure that resists oxidation, helping prevent leakage, and extending pipe lifespan.
Removal Mechanism of Biofilm and Scale
- Biofilm and scale are formed when dissolved minerals and organic matter in water combine and accumulate on pipe surfaces.
- Zinc ions generated inside Jinhaeng RSI bond with negative ions, helping prevent biofilm and scale from adhering to the inner pipe surface.
- Existing hardened deposits gradually loosen, break down, and are removed through ionic reactions.
*Separated rust ions are converted into stable particles and do not affect water quality.
Principles of inhibiting and eliminating bacterial production
Zinc ions generated by Jinhaeng RSI react with water and oxygen to form hydrogen peroxide (H₂O₂).
Active oxygen released from hydrogen peroxide decomposes organic matter in water and helps deactivate bacteria.
Zn + 2H₂O + O₂ + Zn(OH)₂ + H₂O₂

How to Verify Jinhaeng RSI Performance
Performance Verification via Inspection Port
Inspection pipe samples are installed by cutting a section of the pipeline near the water meter to visually confirm product performance.
Once installed, the sample section allows periodic inspection without interrupting water supply.
Through this inspection method, users can directly observe rust (Fe₂O₃) converting into magnetite (Fe₃O₄) and the removal of scale.

Checking the Water Meter Strainer and Toilet Tank Deposits
Product performance can be verified by inspecting and confirming the removal of biofilm formed inside the water meter strainer and toilet tank.
