It is a mixture of fine oil particles dispersed in water as a continuous phase, and is an emulsified water-based fire-resistant liquid with a water content of more than 80%. Its Base Oil is used as a carrier for various additives, and emulsifiers, rust inhibitors, mildew inhibitors, anti-foaming agents and cosolvents are added. Therefore, HFAE emulsion has high specific heat, good flame resistance, excellent cooling performance, cheap and harmless to human body. The anti-rust and anti-corrosion ability of metal materials can be improved as required. Good adaptability to general non-metallic materials. Because it is an aqueous liquid, with high vapor pressure and poor lubricity, the operating temperature cannot exceed 50°C, and the system pressure cannot exceed 7.0MPa. It is suitable for hydrostatic hydraulic system of coal mine hydraulic support and other hydraulic systems or mechanical parts that do not require recycling waste liquid and do not require good lubricity, but require good flame retardant liquid.
It is also a fire-resistant hydraulic fluid with water as a fire-resistant component. It is composed of 30-55% water and 25-45% ethylene glycol, glycerol or its polymers, as well as water-soluble thickeners, anti-wear agent, rust inhibitor, Anti-foaming Agent, etc. The liquid has excellent flame resistance, high viscosity index, good stability and fluidity, and is a transparent true solution. The operating temperature cannot exceed 65°C, and it is generally used in systems with a pressure not higher than 10MPa. It can use the same sealing materials and hoses as mineral oil, but it is different from zinc, cadmium, magnesium, silver and untreated aluminum. Compatible, also can not use leather and cork, can soften ordinary paint, can only be used on epoxy-based paint or vinyl paint. Ethylene glycol has certain toxicity and should be prevented from entering the mouth, but it does not cause harm to the body. Low and medium pressure hydraulic systems for industries such as metallurgy and coal mining.
The above is the What are the types of fire-resistant hydraulic oil and what are the differences in performance? we have listed for you. You can submit the following form to obtain more industry information we provide for you.
