Description
Technical field
The present invention relates to dust suppressant technical field, and in particular to a kind of construction with efficient biodegradable dust suppressant and
Its preparation method.
Background technology
Construction place can often produce substantial amounts of airborne dust, can produce larger pollution to workmen and surrounding environment,
Aggravate haze.It is watering to suppress the most important method of airborne dust, and moisture is soaked dry dust, and is bonded to larger
Grain, avoids it from distally flying upward.But the adhesion between airborne dust and moisture is very weak, moisture evaporates soon, it is impossible to reaches
Good anti-dust effect.
Existing dust suppressant majority uses various chemical medicaments, but all there is anti-dust effect is poor, volatility is serious, no
Can be biodegradable, the problem of producing secondary pollution.
Therefore a kind of efficiently dust suppression is designed, biodegradable construction has very with efficient biodegradable dust suppressant
