The usage method of crust dust suppressant mainly includes three steps: solution preparation, uniform spraying, and natural drying. The core is to ensure the formation of a durable and effective solidification layer on the surface of the material through scientific proportioning and standardized operation to suppress dust.

1. ‌Prepare dust suppressant solution‌

Mix the crust dust suppressant with water in the recommended ratio and stir thoroughly until completely dissolved. The dilution ratio of different products may vary slightly, and the common range is1: 100 to 1:200‌：

• Most polymer based products are recommended to be1:100Proportional preparation (i.e. adding 1 kilogram of dust suppressant per 100 kilograms of water);

• Some biological enzymes or complex products can be diluted to100-200 timesPlease refer to the product manual for specific details.

  
  

• 

The mixing time should not be less than 15-40 minutes to ensure that the dust suppressant is evenly dispersed and avoid clumping that affects the effect. It can be operated using the sprinkler truck's built-in mixing system or specialized mixing equipment.

2. ‌Spray dust suppressant solution‌

Spray the prepared solution evenly onto the target surface, adjusting the spraying amount according to the application scenario and ground conditions:

• ‌Exposed earthworks, construction sites, and mining material pilesThe recommended spraying amount is1.5–3 L/ ㎡Ensure that the surface is fully wetted and permeable to the surface soil;

• ‌Coal transportation or storage yardSpray per square meter1.6–2 LCover the surface of coal to form a high viscosity crust layer;

• ‌Urban roads or temporary construction access roads: Can be appropriately reduced to0.3–0.5 L/ ㎡Emphasis is placed on moisturizing and dust suppressing functions.

‌hintFor some processes, it is recommended to pre wet the ground before spraying dust suppressants, which helps with the penetration of the medicine and uniform film formation.

3. ‌Natural drying and solidification‌

After spraying, there is no need for manual intervention, just let it air dry naturally. As water evaporates, the polymer undergoes cross-linking reactions, forming a tough and waterproof solidified shell layer on the surface. This shell has the characteristics of wind erosion resistance and rainwater erosion resistance, and the dust suppression effect is sustainable30-60 days or even longerSignificantly reduce the frequency of repetitive tasks.
