4631 Water-Glycol Fire-Resistant Hydraulic Fluid 68#

Overview:

Sinopec 4631 Water-Glycol Fire-Resistant Hydraulic Fluid 68# is formulated with water and glycol as the base fluid, and is refined with various additives such as anti-wear agents, antioxidants, rust inhibitors, and anti-foaming agents. According to international standards, it is classified as an ISO L-HFC water-glycol non-flammable hydraulic fluid.

Performance Characteristics:

◎ Excellent flame resistance, ensuring safe use at high temperatures or when exposed to open flames

◎ Extremely low freezing point, ensuring easy starting at low temperatures

◎ Excellent high and low temperature stability (stable true solution), no deterioration, and a storage life of up to two years

◎ Excellent gas- and liquid-phase rust and copper corrosion resistance, meeting gas- and liquid-phase rust prevention requirements

◎ Excellent lubrication properties, ensuring lubrication and service life of the hydraulic pump

◎ Long service life: at least 10,000 hours under normal operating and use conditions.

Technical Specifications:

This product meets the following specifications:

◎ Q/SH PRD122

Applications:

◎ Widely used in hydraulic systems operating in environments exposed to open flames and high temperatures, it serves as an important flame-resistant hydraulic fluid.

◎ Primarily suitable for hydraulic systems requiring fire protection in the steel, coal mining, light industry, chemical industry, mechanical processing, and plastics processing industries.

◎ Operating temperature range: -30°C to 60°C, operating pressure up to 20 MPa.

Parameters:

Precautions:

◎ Avoid mixing with mineral-based hydraulic fluids.

◎ Regularly test the water content in the oil to prevent degradation of its flame-resistant properties.

◎ Generally, open tank temperatures should not exceed 55°C, and closed tank temperatures should not exceed 65°C. Excessive evaporation of water at high temperatures can increase the viscosity of the hydraulic fluid, affecting performance.
