Perfluoropolyether PFPE lubricant, leveraging core properties such as extreme environmental resistance (high/low temperature, chemical inertness), low volatility, high lubrication stability, and no harmful substance emissions, are primarily used for long-term lubrication and protection of critical moving parts in the photovoltaic (PV) industry. They are particularly suited for PV equipment operating outdoors for extended periods (25-year design lifespan), under harsh conditions (temperature fluctuations, sandstorms, UV radiation, humidity), and where maintenance costs are high. Below is a detailed description of specific application scenarios, technical requirements, and typical usage locations.
I. Core Application Scenario 1: PV Tracking Systems (Single-Axis/Dual-Axis Trackers)
1. Application Background
PV trackers are core equipment for improving power generation efficiency (15%-30%). Driven by motors, they rotate PV modules along the sun's trajectory (approximately 20-50 rotations per day, over 10,000 operations annually). Their moving parts are exposed outdoors year-round, facing:
Temperature fluctuations (-40℃~85℃; up to -50℃~95℃ in deserts/plateaus);
Sandstorms, rain, UV radiation, and salt spray (coastal areas);
Low loads and high-frequency start-stop cycles (prone to boundary lubrication).
2. Specific Lubrication Points & Technical Requirements
| Lubrication Point | Function & Technical Requirements | PFPE Lubricant Adaptability |
|---|---|---|
| Spindle Bearings (Slewing Rings/Self-Aligning Bearings) | Bear PV module weight (5-15 tons for single-axis trackers); require low friction, wear resistance, corrosion protection, and a lubricant service life ≥5 years (maintenance-free period). |
- Select PFPE-based greases (thickened with PTFE or PTFE-modified materials) with a dropping point ≥200℃ and low-temperature starting torque ≤5N·m (-40℃);- Chemical inertness ensures no reaction with bearing metals (steel/stainless steel) or seals (NBR/FKM); resists sand adhesion to prevent bearing jamming.
|
| Drive Gearboxes (Worm Gears/Planetary Gears) | Transmit motor power for speed reduction and torque increase; require extreme pressure resistance, anti-scuffing properties, low volatility, and no sludge formation from high-temperature degradation. |
- Choose PFPE gear oils (viscosity grade ISO VG 68/100) with extreme pressure performance (PB value ≥150kgf/cm²) and volatility ≤5% at 120℃ (ASTM D2595);- No carbon deposition, avoiding gear tooth wear or seizure; service life matches gearbox design lifespan (≥10 years).
|
| Connecting Rod/Hinge Joints (Ball Joints/Pins) | Connect tracker frames; require flexible rotation, corrosion protection, and resistance to sandwear. |
- Use PFPE spray lubricants or semi-fluid greases for strong penetration, forming a uniform lubricating film that resists sand adhesion;- UV aging resistance prevents cracking and leakage, adapting to high-frequency swing (angle range ±60°).
|
3. Typical Cases
Desert PV Power Plants: Tracker spindle bearings lubricated with PFPE grease operated continuously for 6 years without maintenance in 60℃ high temperatures and sandy environments, with wear ≤0.02mm;
Coastal PV Power Plants: PFPE lubricants' salt spray corrosion resistance prevented rust on gearbox metal parts and seal swelling, extending service life by over 3x compared to mineral oils.
II. Core Application Scenario 2: PV Module Manufacturing Equipment
1. Application Background
High-precision moving parts of key equipment (e.g., stringers, laminators, scribers) in PV module production require stable lubrication to avoid oil contamination of components (silicon wafers, solar cells, EVA films) while adapting to high-speed, high-precision equipment operation.
2. Specific Lubrication Points & Technical Requirements
| Lubrication Point | Function & Technical Requirements | PFPE Lubricant Adaptability |
|---|---|---|
| String welding machine (Ribbon Traction Mechanisms/Guide Wheels) | Pull tin-plated copper ribbons for precise positioning; require no oil mist, no residual contamination, and no grease migration to solar cell surfaces. |
- Select PFPE dry film lubricants (containing PTFE micropowder) with a film thickness of 0.5-1μm and friction coefficient ≤0.08;- No volatile organic compound (VOC) emissions, avoiding contamination of ribbons or cells that causes poor welding.
|
| Laminators (Hydraulic Systems/Heating Plate Guide Shafts) | Lamination requires high temperatures (130-150℃) and high pressure (0.6-1.0MPa); lubricants must resist high temperatures, be flame-retardant, and odorless. |
- Choose PFPE hydraulic oils (viscosity index ≥150) with viscosity stability ≤±10% at 150℃ and flame retardancy (flash point ≥300℃);- No reaction with EVA films or backsheet materials; odorless and compliant with PV module environmental standards (RoHS).
|
| Scribers (Diamond Dicing Wheel Axles) | High-speed cutting of silicon wafers (linear speed ≥30m/s); require integrated cooling and lubrication to reduce wheel wear and silicon wafer chipping. |
- Use PFPE cutting fluids (5%-10% concentration, water-compatible) for strong lubricity (20% reduction in cutting force) and excellent cooling (silicon wafer cutting temperature ≤40℃);- Residue-free and easy to clean, with no impact on subsequent silicon wafer texturing or coating processes.
|
3. Key Advantages
Full compatibility with PV module materials (silicon, glass, EVA, aluminum frames); no corrosion, adhesion, or component performance degradation;
Low volatility and no oil mist, meeting cleanroom requirements (Class 1000) and reducing equipment cleaning costs during maintenance.
III. Core Application Scenario 3: PV Inverters/Energy Storage Systems
1. Application Background
PV inverters are core for power conversion. Internal moving parts such as cooling fans, contactors, and circuit breakers require long-term stable operation, adapting to high-temperature environments (inverter operating temperature: 60-80℃) while avoiding electrical short circuits from lubricant leakage.
2. Specific Lubrication Points & Technical Requirements
| Lubrication Point | Function & Technical Requirements | PFPE Lubricant Adaptability |
|---|---|---|
| Cooling Fan Bearings (Ball Bearings/Oiled Bearings) | Continuous fan operation (2000-3000rpm); require low noise, long service life, and high-temperature resistance. |
- Select PFPE bearing oils (viscosity ISO VG 22) with a service life ≥20,000 hours at 100℃ and noise ≤35dB(A);- No leakage or volatility, preventing oil droplets from adhering to circuit boards and causing electrical failures.
|
| Contactors/Circuit Breakers (Contact Mechanisms) | Frequent switching (≥10,000 operations annually); require reduced contact wear and improved breaking reliability. |
- Use PFPE contact lubricants (containing nano-PTFE particles) to form a conductive lubricating film with contact resistance ≤10mΩ;- Arc and oxidation resistance prevents contact ablation, extending service life by 3-5x.

IV. Core Technical Advantages of PFPE Lubricants in the PV Industry
Extreme Environmental Resistance: Operating temperature range of -60℃~250℃, adapting to complex climates (deserts, plateaus, coastal areas) without solidification or carbonization;
Chemical Inertness: No reaction with metals, plastics, rubber, silicon wafers, or EVA, ensuring no corrosion, swelling, or contamination;
Long-Term Lubrication: 3-5x longer service life than mineral oils, with a maintenance-free period of 5-10 years, reducing PV plant operation and maintenance (O&M) costs by over 40%;
Environmental Compliance: Free of heavy metals and VOCs, compliant with RoHS and REACH standards, aligning with the PV industry's "green energy" positioning;
Low Volatility/Low Migration: No oil mist contamination of components or electrical equipment, reducing product defect rates.
V. Selection Considerations
Viscosity Matching: Choose appropriate viscosity based on load and speed (e.g., VG 100-150 for high-load gearboxes, VG 22-46 for high-speed bearings);
Thickener/Additives: For outdoor equipment, prioritize PTFE-thickened greases (sand and water resistance); for precision equipment, select additive-free types (to avoid contamination);
Compatibility Testing: Conduct compatibility tests with seals (FKM, silicone rubber) and materials (EVA, backsheets) to ensure no swelling or aging;
Certifications: Prefer products with PV industry certifications (e.g., TÜV, UL) to meet equipment design requirements.
