Product Features
The PP electrolytic tank can operate at temperatures up to 95°C.
It has excellent electrical insulation and extremely low water absorption, making it unaffected by humidity.
The material's individual dielectric constant and dissipation factor are very low and unaffected by frequency and temperature.
The PP sheet's dielectric strength is high, increasing with increasing operating temperature.
Typical Structures
- Single-layer thick-walled tank: Commonly made of 12–20 mm PP sheet, bent and welded in one piece, with a corner seam coefficient ≥0.7, and hydrostatic pressure resistance ≥10 kPa; externally reinforced with steel frames to prevent sidewall bulging when full of liquid.
- Composite-lined tank: An 8–10 mm PP sheet is applied to the inside of a reinforced concrete or steel shell, with a layer of fiberglass mesh and adhesive in between, combining rigidity and corrosion resistance. This type is often used in copper electrolytic refining or electrowinning, with a single tank volume reaching 3 m × 1.2 m × 1.2 m, producing 10 tons of cathode copper per day.
- Integrated functions: The tank ends integrate overflow boxes, circulation ports, exhaust ports, and thermometer sockets; the bottom is sloped ≥2° and equipped with a DN50 drain valve for easy cleaning and anode sludge recovery.
Application Areas
Electroplating Industry
As an anodizing tank, the number of new alkaline electrolyzer product releases in Q1 2025 decreased by 40% year-on-year, with technological iteration shifting towards energy efficiency improvements.
Hydrogen Energy Industry
PEM electrolyzer single stack power exceeded 3.5kW/L. Toyota's new titanium bipolar plate reduces volume by 23%, improving the integration of megawatt-level systems.
