Solution-Type Concentrate for Hydraulic Supports in Coal Mines
HFAS10-4 type solution concentrate is intended for preparing high-water-content hydraulic fluid used in coal mine hydraulic props and related mining hydraulic systems. It provides rust protection, corrosion control, water dispersibility, foam control, and compatibility with suitable sealing materials. Bulk purchasing, OEM, and export cooperation are available.
HFAS10-4 is a solution-type concentrate used to prepare water-containing hydraulic fluid for mine hydraulic props, outdoor hydraulic props, and other underground mining hydraulic equipment. Before application, the concentrate is mixed with suitable water according to the specified concentration and water quality requirements.
The formulated working fluid is designed to provide rust protection for ferrous metal parts, corrosion control for compatible non-ferrous metals, lubrication, foam control, fluid stability, and compatibility with suitable sealing materials. Proper water quality, mixture concentration, and system maintenance are important for reliable operation.
