Product introduction:
Maximum operating temperature of SINOPEC 4631 water-glycol fire resistant hydraulic fluid:
The open tank should not exceed 55°C, and the closed tank should not exceed 65°C. Otherwise, the temperature will be too high and water will evaporate too much, which will increase the viscosity of the hydraulic fluid and affect its use;
When using SINOPEC 4631 water-glycol fire resistant hydraulic fluid, attention should be paid to its compatibility with metals and non-metals;SINOPEC 4631 water-glycol fire resistant hydraulic fluid is compatible with the following commonly used materials:
Epoxy resin, phenolic resin, bronze (containing P. <20%), brass, copper, plastic products, nitrile rubber, fluorine rubber, silicone rubber, polytetrafluoroethylene, nylon and treated with celluloid and phenolic resin Paper, etc.; SINOPEC 4631 water-glycol fire resistant hydraulic fluid is prohibited from being mixed with mineral oil, emulsion and ester hydraulic media. Before use, the hydraulic system should be cleaned and then filled with SINOPEC 4631 water-glycol fire resistant hydraulic fluid. fluid;
During the use of SINOPEC 4631 water-glycol fire resistant hydraulic fluid, the appearance, kinematic viscosity, pH value, foam, etc. of the oil should be checked regularly (usually 3 months), and any problems found should be dealt with promptly.
