Coal MineDustfall Agent Introduction

Mine dust agentmain effective components in new type of multi-functional polymer, advanced andreliable dustfall and the mechanism of dust thrown back on the one hand canrock dust in coal mine production, wow dust, coal mine to realize efficient moisturizing,the other party due to the crosslinking degree of polymer molecules form a meshstructure, charge density, and ion affinity strong, can quickly capture andadsorption of dust particles and to promote the better and, this product'sprinciple and other dust dust products, other dust products are dust in the airflow after began to governance, and the sources of our dustfall agent is in thedust began to fall, the source of the powder point began to dust, dust in thebud, the mechanism of dust is advanced. Especially suitable for fullymechanized coal face, comprehensive tunneling working face, the face ofspray.Dust effect and working face coal dust can reduce more than 90%, concretejet points may be dust concentration decreased more than 40%, on the fluidity,strength and setting time of concrete has no obvious influence.

Coal MineDustfall Agent Parameters

1）Mixed with concrete toadd product in accordance with the proportion of 1:0 after water, stir well,will be added to the solution of this product directly used as concrete mixingwater.

2）Spray will this productaccording to 00 when the proportion of added in water, stir well, will be addedto the solution of this product to join the spraying equipment, coal spray dustwhile working or high dust or spray on high area.Suitable for fully mechanizedcoal face, comprehensive tunneling working face, the face of spray.
