Chemi Tech Composite Enamel Enhances Durability of Farming Components

No-till planter openers face combined abrasion (SiO₂ ≥7 Mohs) and fertilizer corrosion in black soil. Chemi Tech's KMB-3430 enamel delivers full-cycle protection through metal-ceramic reinforcement.

Technical Innovations

Wear-Resistant Matrix: WC hard phase (2-5μm) forms a honeycomb structure, limiting abrasive embedment depth to 0.3mm；

Corrosion Barrier: Dense α-Al₂O₃ layer (porosity ≤0.8%) blocks Cl⁻ penetration, achieving 1500-hour salt spray resistance.

Field Results

Northeast Black Soil Test:

Planter openers coated with KMB-3430:

▶ Wear ≤0.5mm after 1800 acres (vs. failure at 600 acres previously)；

▶ 15% lower fuel consumption due to reduced draft force；

Economic Impact:

▶ Annual maintenance cost/planter: ¥38,000 → ¥11,000；

▶ Corn emergence rate ↑9.7% from consistent furrow depth.

Adaptive spraying ensures ±15μm thickness uniformity on complex geometries.
