Περιγραφή προϊόντων
Prepackaged Magnesium Sacrificial Anode Backfill for Dry Rocky Sandy Soil
This prepackaged magnesium sacrificial anode features a carefully formulated backfill mixture designed to overcome the challenges of high resistivity dry rocky and sandy soil environments. The backfill material creates a localized low-resistivity zone around the anode, ensuring consistent current output even when the surrounding soil lacks sufficient moisture and electrolyte conductivity.
Backfill Technology for Challenging Soil Conditions
- Optimized Backfill Formula: 75% Gypsum + 20% Bentonite + 5% Sodium Sulphate creates a moisture-retaining and ionically conductive environment that sustains anode activity in dry soil
- Rapid Wetting Properties: The backfill mixture absorbs and retains moisture, creating a protective conductive envelope that prevents anode passivation in sandy and rocky terrains
- Environmental Safety: Backfill contains harmful elements below international safety standards: Cadmium ≤1ppm, Arsenic ≤1ppm, Mercury ≤1ppm, Lead ≤10ppm
- Self-Conditioning: As the anode discharges, the backfill maintains a stable chemical environment that prevents the formation of resistive films on the anode surface

Performance in Different Soil Conditions
| Soil Type | Typical Resistivity | Backfill Benefit | Protection Level |
|---|---|---|---|
| Dry Sandy Soil | 5,000-10,000 ohm·cm | Moisture retention + ionic conductivity | Excellent |
| Rocky Terrain | 3,000-15,000 ohm·cm | Contact surface enhancement | Excellent |
| Gravel / Stony Soil | 2,000-8,000 ohm·cm | Uniform current distribution | Very Good |
| Moist Clay Soil | 500-2,000 ohm·cm | Enhanced current output | Good (bare anode sufficient) |
| Wet Organic Soil | 200-1,000 ohm·cm | Extended service life | Good |
Key Advantages Over Bare Anodes in Difficult Soil
- Eliminates Dry Contact Issues: The backfill fills voids between the anode and rocky/sandy soil, maximizing effective contact area
- Reduces Ground Resistance: Backfill lowers the anode-to-earth resistance by up to 40% compared to bare anodes in sandy soil
- Uniform Current Distribution: Ensures even consumption of the anode material, maximizing service life and cost-effectiveness
- Simplified Installation: Ready-to-install with pre-attached cable, eliminating the need for on-site backfill mixing
Applications
- Underground pipelines in desert and semi-arid regions
- Storage tank farms in sandy soil environments
- Well casings and sub-surface structures in rocky terrain
- Pipeline networks in mountainous and gravel-rich areas
- Electrical grounding grids requiring corrosion protection in dry soil
- Gas distribution networks in high resistivity soil conditions
