TANMNG
Conditions: 85–98% relative humidity, 40–80°C steam, continuous water impact.
Challenges: Rust, coating peeling, and reduced vacuum efficiency due to water penetration.
Tianmeng’s Solution: HVOF tungsten carbide ceramic coatings (porosity <1%) form a dense barrier against moisture and steam, ensuring long-term stable vacuum adsorption.
Conditions: High-concentration pulp, recycled paper with impurities, and high-speed fiber friction.
Challenges: Severe wear, blocked suction holes, and uneven dewatering.
Tianmeng’s Solution: High-hardness composite coatings (microhardness ≥1200HV) offer 3–5x higher wear resistance than traditional chrome plating, resisting fiber abrasion and keeping suction holes unobstructed.
Conditions: Residual acids/alkalis, sizing agents, and filler deposits (calcium carbonate, clay).
Challenges: Chemical erosion, scaling, and frequent cleaning shutdowns.
Tianmeng’s Solution: Anti-fouling & anti-corrosion customized coatings (e.g., PTFE composite, nickel-based alloy) repel pulp residues and chemicals, reducing maintenance frequency by 60%+.
Conditions: Paper machine speed ≥1000 m/min, wide web (2–10 m), and 24/7 continuous operation.
Challenges: Vibration, fatigue, and inconsistent vacuum pressure.
Tianmeng’s Solution: Precision-machined roll bodies + reinforced coatings ensure structural stability and uniform vacuum distribution, supporting high-speed production without paper breaks.
As a professional thermal spray coating manufacturer with only years of experience, Tianmeng uses HVOF, plasma, and arc spray processes to apply high-performance coatings tailored to harsh environments:
Tungsten Carbide Ceramic Coating: For high-wear pulp zones; hardness ≥1200HV, wear resistance 3–5x chrome.
Anti-Fouling PTFE Composite Coating: For chemical/fouling environments; surface tension ≤18 mN/m, prevents fiber adhesion.
Nickel-Based Alloy Coating: For strong corrosion; resists acids/alkalis, extends service life to 3–5 years.
High-Density Sealing Coating: For high-humidity zones; porosity <1%, blocks moisture penetration.
Tianmeng’s vacuum pick-up rolls are engineered for long-term stability:
Consistent Vacuum Performance: Uniform suction hole layout + smooth coating surface ensure stable negative pressure (0.02–0.08 MPa), eliminating paper breaks, wrinkles, and deviations.
Low Maintenance & Long Lifespan: Coatings resist wear, corrosion, and fouling; suction holes stay unblocked, reducing downtime by 70% vs. ordinary rolls.
Structural Reliability: High-strength steel roll bodies + precision welding withstand high-speed vibration and heavy loads, avoiding deformation.
We provide one-stop non-standard customization to match any paper machine’s parameters:
Diameter: φ100 mm – φ800 mm
Face Length: 500 mm – 10,000 mm
Wall Thickness: 10 mm – 50 mm
Suction Hole Layout: Custom density (3–5 holes/cm²) and diameter (0.1–0.5 mm)
