DEVELOPMENT OF FIRE RESISTANT WATER BASED HYDRAULIC FLUIDS

Pagination or Media Count:
Hydraulic fluids consisting of polyglycols, water and corrosion additives have been formulated whose properties meet or approach those proposed in the contract targets. The fire resistance characteristics of the finished lubricant were studied with inhibitors based on boron, phosphorus, or chlorine containing materials. Nitrogen and highly conjugated ring structures were incorporated into the major fluid components. Simulated hydraulic system tests have been used to establish the actual performance of the proposed hydraulic fluid base formulas.
