Compound dust suppression agent for coal mine and preparation method of compound dust suppression agent
A dust suppressant and coal mine technology, applied in mining equipment, dust prevention, earth square drilling, etc., can solve the problems of unable to meet the dust concentration standard, low removal rate of respirable dust, etc., and achieve the effect of simple construction and wide range of raw materials
Examples
Embodiment 1
[0017] Weigh 0.08g of polyacrylamide and dissolve it in 200ml of distilled water, place it in a water bath at a temperature of 50°C, heat and stir until the solution becomes colorless and transparent, then slowly add 0.8g of JFC dropwise under stirring, and continue to stir. Composite dust suppressant for coal mine can be obtained.
Embodiment 2
[0019] Weigh 0.04g polyacrylamide and dissolve it in 200ml distilled water, place it in a water bath at 50°C, heat and stir until the solution becomes colorless and transparent, add 0.4g SDBS, then slowly add 0.4g dropwise under stirring JFC and 0.12g PAC, continue to stir to prepare the composite dust suppressant for coal mine.
Embodiment 3
[0021] Weigh 0.06g of polyacrylamide and dissolve it in 200ml of distilled water, place it in a water bath at a temperature of 50°C, heat and stir until the solution becomes colorless and transparent, then slowly add 0.2g of JFC and 0.12g of PAC successively under stirring , and continue to stir to obtain a composite dust suppressant for coal mines.
