2、 Characteristics
Extreme pressure anti-wear and high-efficiency lubrication performance
Extreme pressure additive system:
Composite sulfide+chlorinated paraffin: forms a chemical adsorption film with a thickness of 1-3 μ m, with a load-bearing capacity of 700kg (PB value, ASTM D2783 standard), which is 55% higher than traditional mineral oil (PB value 450kg). When drawing a copper wire with a diameter of 1.2mm to a diameter of 0.8mm (surface reduction rate of 33%), the mold life is extended to 800 tons (traditional oil is only 500 tons).
Wear resistance and durability: Under the Falex four ball test (load 392N, speed 1200rpm), the wear spot diameter is 0.42mm (ASTM D4172 standard), and the wear resistance life reaches 6000 cycles, which is 2.5 times that of ordinary oil, reducing the fluctuation of wire diameter caused by mold wear (± 0.003mm → ± 0.001mm).
Friction coefficient optimization:
Dynamic friction coefficient: In the steel copper friction pair, μ=0.08 (47% lower than mineral oil μ=0.15), the pulling force is reduced by 18%, and the energy consumption cost is saved by 12% (calculated based on a daily energy line of 10 tons, saving about 80000 kWh of electricity per year).
Boundary lubrication efficiency: A "liquid solid" mixed lubrication film is formed in the entrance area of the mold, effectively suppressing the adhesive wear between the copper wire and the mold. The wire breakage rate is reduced from 0.5% to 0.15%, and the qualification rate is increased to 99.5%.
Low residue and efficient cleaning performance
High temperature volatility control:
Volatile rate at 120 ℃/24h: ≤ 1.2% (TGA thermogravimetric analysis), reducing oil film residue by 80% compared to traditional oils (volatile rate ≥ 3%), avoiding the formation of "oil spots" defects in the insulation layer of enameled wire after baking (reducing the risk of insulation breakdown by 90%).
Residual components: carbide content ≤ 0.5% (weight ratio), solubility of cleaning agent ≥ 95% (isopropanol ultrasonic cleaning for 10 minutes), suitable for automated spray cleaning lines, reducing cleaning costs by 30%.
Filter compatibility:
Filter life: Supports continuous use of 5 μ m glass fiber filter for 1000 hours (three times longer than mineral oil filter life), with a filtration efficiency of ≥ 99.5%, ensuring oil cleanliness below NAS level 7, and reducing wire scratches caused by particle pollution (scratch depth ≤ 0.5 μ m).
Multi metal protection and chemical stability
Copper/Aluminum/Steel Compatible Protection:
Copper corrosion suppression: Neutral salt spray test (ASTM B117) for 720 hours without red rust, copper surface contact resistance change rate ≤ 3% (initial value 0.5m Ω), avoiding resistance fluctuations caused by corrosion (± 0.015m Ω → ± 0.005m Ω).
Aluminum wire compatibility: In the drawing of copper-clad aluminum wire (Cu/Al volume ratio 7:3), there is no risk of hydrogen embrittlement in the aluminum layer (hydrogen content ≤ 0.2ppm), and the tensile strength retention rate is ≥ 95% (traditional oil ≤ 85%), meeting the requirements of low loss for high-frequency signal transmission wire (conductor resistivity ≤ 0.027 Ω· mm ²/m at 20 ℃).
Chemical stability:
Acid value control: After aging at 100 ℃ for 1000 hours, the acid value increases by ≤ 0.15mgKOH/g (GB/T 264 standard) to avoid corrosion of the mold by acidic substances (mold hardness decrease ≤ 1HRC), and reduce the frequency of mold replacement (monthly average replacement frequency reduced from 3 times to 1 time).
Hydrolytic stability: stored in a 95% humidity environment for 7 days, with a viscosity change rate of ≤ 5% (40 ℃), and an oil emulsification tendency rating of level 1 (ASTM D2619 standard), ensuring continuous lubrication performance in humid environments.
Environmental Protection and Operational Safety
Biodegradation and low toxicity:
OECD 301F biodegradation rate: ≥ 85% (28 days), reducing the cost of waste oil treatment by 50% (difficult to degrade oil), in compliance with the EU ELV directive, suitable for export processing of automotive wiring harnesses.
Acute oral toxicity: LD50>5000mg/kg (rats), operators do not need to wear gas masks, workshop VOCs emission concentration ≤ 20mg/m ³ (below the national standard limit of 80%), improving the health risks of the working environment.
Flash point and explosion safety:
Flash point: ≥ 200 ℃ (COC method), fire risk level is "Flammable - Level 2" (NFPA 704 standard), with a 25% increase in safety compared to mineral oil (flash point ≤ 160 ℃), suitable for unmanned intelligent workshops.
Static dissipation: Surface resistivity ≤ 10 ¹⁰ Ω (ASTM D257 standard), avoiding static sparks generated by oil friction in pipelines (static voltage ≤ 50V), and eliminating the risk of explosion.
3、 Application scenario analysis
High voltage wire harness processing for new energy vehicles
800V platform copper bar drawing:
When pulled to a diameter of 1.5mm (with a surface reduction rate of 67%) in a copper bar with a diameter of 3.0mm, the JF-905 oil film can withstand an instantaneous pressure of 1000MPa, and the surface roughness Ra decreases from 1.2 μ m to 0.6 μ m. After twisting, the conductor resistivity decreases by 8% (compared to unlubricated conductors), meeting the low loss requirements of an 800V fast charging system.
After 1000 cycles of cold and hot shock from -40 ℃ to+150 ℃, the resistance change rate of copper wire used in conjunction with JF-905 is ≤ 0.8%, ensuring the stability of high-voltage transmission from the battery pack to the motor.
Lacquered flat wire fine drawing:
In the drawing of a flat wire with a diameter of 0.8 × 2.0mm, the oil film thickness can be controlled to 1.5 μ m, the wire breakage rate can be reduced from 0.3% to 0.08%, and the wire diameter tolerance is ± 0.005mm (measured ± 0.003mm), which is suitable for the design requirement of a stator slot full rate of ≥ 75% for flat wire motors.
Production of communication base station feeders and jumpers
5G high-frequency coaxial cable:

After rapid curing at 200 ℃/20 seconds, the oil film forms an insulation layer with a dielectric constant of ε ≤ 2.2 and an insertion loss of ≤ 0.12dB (6GHz), suitable for millimeter wave communication harnesses.
Fiber optic patch panel jumper:
Used for drawing Φ 0.25mm copper alloy wire, with a friction coefficient of μ=0.09 between the oil and copper iron nickel alloy, a jumper insertion and removal life of ≥ 1000 times (traditional oil only 700 times), and a contact resistance change rate of ≤ 5% (initial value 20m Ω).
Photovoltaic inverters and energy storage cables
High current photovoltaic DC line:
When pulled to a diameter of 1.2mm in a copper wire with a diameter of 2.0mm, the JF-905 oil film reduces the conductor resistance by 6% (compared to the dry pulling process), reduces the line loss of the 1500V system by 0.3%/km, and improves the power generation efficiency of the photovoltaic power station.
The oil has passed UL 44 certification, with a temperature resistance level of -40 ℃ to+125 ℃. After being stored in a desert environment (70 ℃/20% humidity) for 1 year, the copper wire contact resistance change rate is ≤ 2%, ensuring the long-term reliability of the energy storage system.
Copper busbar processing for combiner box:
When pulled to 4mm in T2 copper bar (thickness 6mm), JF-905 reduces mold wear by 40%, increases surface hardness by 10HV (Brinell hardness tester), bends 90 ° without cracks, and meets the IP68 protection level of the combiner box design.
