Description
Technical field
The invention belongs to dust suppressant technical fields, and in particular to a kind of dust suppressant.
Background technique
As the dust on the roads of one of the source of atmospheric pollution, existing governing measure is mainly street cleaning and watering is most often
Dust-suppression method is sprayed by road pavement, increases pavement humidity to inhibit dust on the roads, or nothing is added in sprinkling truck
Machine salt dust suppressant extends anti-dust effect with this to increase the road surface wet time.Its main function is by wet
Increase the water capacity of dried dust, density increases and is bonded to biggish particle.That sprinkles water is easy to operate, but winter is easy knot
Ice, summer evaporation is fast, and effective dust suppression time is insufficient half an hour, and water consumption is big.Micronic dust content after moisture evaporation can increase severely
600%.
Road surface watering and lowering dust can inhibit fugitive dust in the case where road surface is wet, however after moisture evaporation, and dust again can be
Wheel roll and air-flow under the action of enter in atmosphere, i.e., anti-dust effect is unsustainable after road surface is dry.It is long-term to keep road surface
It is wet to greatly increase cost of labor and water consumption, while increasing sprinkling frequency and can also improve the dosage of fossil fuel.Inorganic salts
Class dust suppressant (CaCl2、MgCl2Deng) cheap, it is widely used as Road dust suppressant, but can excessively lead using such dust suppressant
Cause the negative consequences such as the salinization of soil, road of mating formation corrosion.
Chemical dust suppressant it is various in style, the primary raw material for compounding has inorganic low molecular compound, organic low molecular
Compound and high-molecular compound.The cost of the inorganic matters such as calcium chloride, magnesium chloride, aluminium chloride, sodium sulphate, waterglass is low, uses
Conveniently, antifreezing effect is good, but anti-dust effect is not good enough, corrodes metal, contaminated soil, intolerant to rain-out.Ethylene glycol, a contracting diethyl
The organic matters such as glycol, glycerine can infiltrate, be adsorbed in dust particles surface, have and absorb moisture, keep moisture and reduce solidifying
The effect of solid point, but have the shortcomings that durability is poor, it can not solve the problems, such as natural evaporation and rain-out.Cinder is oily, wooden slag is oily,
Shale residual oil, light oil, heavy oil, coal tar, reconciliation residual oil, soft resin and fluxed bitumen still fall within low molecule organic matter, to powder
Dirt particle surface has preferable infiltration, absorption and a degree of film forming coating function, but there are apparent corrosion resistance and suppressions
The disadvantages of dirt low efficiency.Therefore a kind of dust suppressant that dust suppression is high-efficient need to be developed.
