Antioxidant and anticorrosion additive
Antioxidants and anticorrosion additives are vital components in lubricants and other industrial fluids to protect against oxidative degradation and corrosion, respectively. These additives help maintain fluid stability, extend equipment life, and ensure optimal performance in various applications.
Antioxidant and anticorrosion additives are crucial components found in lubricant additive packages for various applications, including engine oils, gear oils, and hydraulic oils.
Product introduction：
Zinc Butyl Octyl Primary Alkyl Dithiophosphate (ZDDP) is a widely used additive in lubricant formulations, particularly in engine oils, to provide essential anti-wear, antioxidant, and corrosion protection properties. ZDDP is a multifunctional additive that plays a crucial role in extending the service life of engines and protecting critical engine components under various operating conditions.
Product introduction：
Zinc Dioctyl Primary Alkyl Dithiophosphate (ZDDP) is a specialized type of ZDDP additive used in lubricant formulations to provide anti-wear, antioxidant, and corrosion protection properties. Similar to other ZDDP derivatives, Zinc Dioctyl Primary Alkyl Dithiophosphate contains zinc and phosphorus compounds that interact with metal surfaces to form a protective film, reducing friction and wear between moving parts in engines and machinery.
Product introduction：
Zinc Secondary Dialkyl Dithiophosphate (ZDDP) is another variant of ZDDP used as an additive in lubricant formulations to enhance anti-wear, antioxidant, and corrosion protection properties. This type of ZDDP contains secondary dialkyl groups and is widely employed in engine oils, industrial lubricants, and other functional fluids.
Product introduction：
Zinc primary-secondary alkyl dithiophosphate (ZDDP) is a specialized type of ZDDP additive used in lubricant formulations to provide anti-wear, antioxidant, and corrosion protection properties. This type of ZDDP contains both primary and secondary alkyl groups, offering enhanced performance benefits compared to conventional ZDDP additives.
About anti-wear additive Zddp
Key Characteristics of ZDDP:
- Anti-Wear Protection: ZDDP forms a protective film on metal surfaces, reducing friction and wear between moving parts, especially under boundary and mixed lubrication conditions.
- Oxidation and Thermal Stability: ZDDP helps to inhibit the oxidative degradation of the base oil, extending the service life of the lubricant and maintaining its viscosity and performance at elevated temperatures.
- Corrosion Protection: ZDDP provides excellent corrosion protection by forming a protective barrier on metal surfaces, preventing rust and corrosion, especially in engines where water and acidic combustion by-products may be present.
- Anti-Foaming: ZDDP can also act as an anti-foaming agent, reducing the formation of foam in the lubricant, which can lead to reduced lubrication efficiency and potential damage to engine components.
Applications of ZDDP:
- Engine Oils: ZDDP is primarily used in engine oils for passenger cars, motorcycles, and heavy-duty diesel engines to provide enhanced wear protection, oxidation resistance, and corrosion protection.
- Industrial Lubricants: ZDDP is also used in various industrial lubricants, including hydraulic fluids, gear oils, and metalworking fluids, where anti-wear and extreme pressure (EP) properties are required.
- Additive Compatibility: ZDDP is generally compatible with other additives used in lubricant formulations, such as detergents, dispersants, and viscosity modifiers, allowing for versatile formulation options.
Considerations:
- Phosphorus Content: ZDDP contains phosphorus, which can have adverse effects on certain exhaust aftertreatment systems, such as catalytic converters and diesel particulate filters (DPF). Therefore, the phosphorus content in engine oils is often regulated to comply with emission standards and protect these systems.
- Treat Rate: The treat rate of ZDDP in lubricant formulations should be optimized to achieve the desired performance benefits without exceeding the recommended limits for phosphorus content.
