Problems solved by technology

[0002] At present, with the continuous improvement of the level of coal mining technology, comprehensive mechanized equipment is being used in large quantities in mine mining, especially the use of the hydraulic system is the largest, because the hydraulic system used is mixed in proportion by emulsified oil and water. The final emulsion, when used in the case of high water hardness, will cause oil and soap precipitation in the hydraulic system, and these precipitated oil and soap will adhere to the hydraulic prop and filter net, seriously affecting the equipment. normal use
However, even a good solvent such as acetone cannot clean these separated oils and soaps. In order to reduce the amount of separated oils and soaps, demineralized water and emulsified oils have to be used to prepare emulsions. However, in places where water resources are scarce In the absence of water softening equipment in the region or in the absence of water softening equipment, this is undoubtedly a trouble in the production work, and there is no relevant report on the cleaning fluid that can thoroughly clean oil and soap substances.

Abstract

The invention provides a kind of clean soap class matter function cleaning liquid, its component is: Five water sodium metasilicate, EDTA four sodium salt, sodium benzoate, triethanolamine, Twain -80, deionized water; Its preparation method: (1) solution preparation: Five water sodium metasilicate, the EDTA four sodium salt and the sodium benzoate, dissolve in the deionized water, namely made has been ready to be used the fluid; (2) mixes the process: -80 dissolves Twain to is ready to be used in the fluid which makes, makes the reserve fluid, again joins the triethanolamine in the reserve fluid, then continues to stir for a hour, has made the end product. The invention states the clean soap class matter uses the cleaning liquid, its PH value is 8-10, after carries on the clean test, dissolves the oil, dissolves the soap time not to be bigger than 30 minutes, realized fast has mounted is attached to the hydraulic system the emulsion aspiration oil, the soap dissolves, the elimination goal, therefore solubility good, because used the raw material to include the highly effective antiseptic, therefore, corrosiveness low, the security was high, specially was suitable for to the mine pit hydraulic system clean.
