Thermal Oil Additive Package Heat Oil Additive Hybrid Lubricant
Intelligent Deposit Control & Thermal Stability Booster for Heat Transfer Systems
Effectively alleviate the tendency of heat transfer oil to coke after long-term use.
Thermal Oil Additive Package can be used to prepare L-QB280, L-QB300, L-QC320, LQD-350 heat transfer oil.
L-QB can be used in open or closed heat transfer systems with forced or non-forced circulation. L-QC can be used in open or closed heat transfer systems with forced circulation.
When the flash point (opening) is lower than the specified index, the heat transfer fluid must be used in a closed heat transfer system. When the initial boiling point is lower than the maximum operating temperature, the heat transfer oil must be used in a closed heat transfer system.
L-QD can be used in a forced circulation closed heat transfer system with a maximum operating temperature higher than 320℃ and less than 350℃
Product Introduction
This Hybrid Lubricant is a multi-functional hybrid additive package engineered for thermal oils operating at 300°C+ temperatures. Its synergistic blend of aromatic stabilizers, nano-dispersants, and organoboron anti-coke agents combats sludge formation, enhances thermal conductivity, and extends fluid life in systems vulnerable to oxidative degradation and fouling.
Performance Advantages
- Deposit Dissolution & Prevention
Liquefies existing coke deposits (up to 85% viscosity reduction in fouled oils) and suppresses new sludge formation by neutralizing dehydrogenation radicals.
- Thermal Stability Enhancement
Extends oxidation induction time (OIT) by 3x via PDSC testing (ASTM D6186), enabling 400°C peak operation without cracking.
- Fuel Economy Optimization
Reduces fuel consumption by 15%+ via improved thermal conductivity (0.145→0.165 W/m·K) and minimized fouling-induced heat transfer losses.
- Multi-Metal Protection
Chelates iron/copper ions from thermal degradation byproducts, reducing corrosion rates by 70% (ASTM D665 seawater test).
- System Safety Assurance
Elevates auto-ignition temperature to 450°C+ and reduces volatile content (ASTM D1160 distillation 90% point >340°C).
