I. Good lubrication performance
The emulsion can form a lubricating film on the surface of the moving parts of the mining support. For example, during the expansion and contraction of the column and jack of the hydraulic support, the emulsion can effectively reduce the friction between the metal parts. This is like putting a layer of "lubricant clothing" on the mechanical parts, which reduces the friction coefficient, makes the movement of the stand smoother, reduces the wear and tear of the parts, and thus prolongs the service life of the equipment.
Second, excellent anti-rust performance
The underground environment of the mine is characterized by high humidity and the presence of various corrosive substances. The antirust agent in the emulsion can form a protective film on the metal surface, preventing the metal from contacting with water, oxygen and other corrosive media. For example, for the steel structure part of the stent, the emulsion can prevent the acidic water in the mine from rusting, just like giving the metal stent a shot of "anti-rust preventive needle" to ensure that the stent works stably for a long period of time in the harsh underground environment.
Third, good cooling effect
Mining stent in the working process, the hydraulic system will produce heat because of energy conversion. The emulsion can take away the heat in the process of circulation and play the role of cooling. For example, when the hydraulic stent is frequently lifted and lowered, the emulsion can absorb and take away the heat generated by the hydraulic system, maintain the normal working temperature of the system and prevent the equipment from failing due to overheating, just like installing a "radiator" to the hydraulic system of the stent.
Four, good stability and adaptability
The emulsion has good chemical stability and anti-foaming property. In the complex mining environment, even if it is polluted to a certain extent or the temperature changes, the emulsion is still able to keep its performance stable. For example, in different underground mining areas, the temperature and water quality may vary, but the emulsion can adapt to these changes, can still play its normal lubrication, rust prevention and other functions, will not easily appear delamination, deterioration and other phenomena.
Fifth, high safety
Emulsion is not easy to burn, compared with some combustible gases and dusts underground, it has high safety. In mines with flammable and explosive gases such as gas, the use of emulsion as the working medium of mine support can reduce the risk of fire and explosion, providing a guarantee for safe production in mines.
Sixth, better cost-effectiveness
The cost of emulsion is lower compared with some other special hydraulic media. And because of its good performance can extend the service life of mining support equipment, reduce the frequency of equipment maintenance and replacement, in the long run, can save a lot of equipment maintenance and renewal costs for mining enterprises.
