Coal mine machinery and equipment is a large-scale mechanical equipment excavated in coal mine; transport; transport; including mining machine; conveyor; well roadway excavation equipment; underground auxiliary transportation, vehicle equipment; mine winch; ventilation and dust removal equipment; coal washing Equipment; cranes; special vehicles, etc.
The mechanical equipment produced in the coal mine has the following characteristics:
1. The working environment is bad; the equipment is surrounded by dust, water vapor and harmful gases.
2. Working conditions are harsh; most mechanical equipment is operated under conditions of high speed, heavy load, oscillation, shock, collision and medium corrosion.
3. Long running time; most of the machinery and equipment do not stay up all night;
4. Poor smooth conditions; because of the harsh environment; harsh working conditions; plus short stop time; this makes mechanical parts not outstanding smooth and protective.
Thus, the economic losses that are formed each year are staggering; as long as the correct bearings are selected; the protection is carried out regularly; the protection is timely; the quality of the protection is improved; the production equipment is guaranteed to operate in an outstanding state; the mechanical wear of the coal mine is reduced; Life expectancy; complete high-yield, efficient and safe production of coal; effective operation of mining operators to ensure higher yield; to achieve the expected service life of the equipment.

Dyrect Dyes are Direct Dyes applicable to cotton, Paper, Leather, rayon and linen, with good light fastness. Direct or substantive dyeing is normally carried out in a neutral or slightly alkaline dyebath, at or near boiling point, with the addition of either sodium chloride (NaCl) or sodium sulfate (Na2SO4) or sodium carbonate (Na2CO3).
