Static blasting agent

Introduction: Static blasting agents play an important role as a necessary item in the traditional construction method of static blasting.

Static blasting agent is a kind of gray powder material with high expansion performance made of a variety of inorganic materials, also known as: silent breaker, static breaker, expansion cement, rock expansion agent, vermiculite agent and so on. With a suitable amount of water, it can be transferred into a fluid slurry and directly poured into the borehole. After the hydration reaction, the crystal is deformed, and a huge expansion pressure (radial compressive stress and circumferential tensile stress) is generated over time and applied to the hole. wall. The expansion pressure is proportional to the reaction time, ie, the longer the time, the greater the expansion pressure; the time required for the cracking of the object is inversely proportional to the ambient temperature, ie, the higher the temperature, the shorter the required time.

At present, static blasting agents are mainly used for the cutting and crushing of rocks and the removal and crushing of (rebar) concrete buildings.

Static blasting agents have the following advantages:

1. Safety: The static blasting agent has no vibration, no noise, no flying stones, no dust, no harmful gas during the expansion of cracked objects.

2. Controllable: It can design different drilling according to different needs of customers to achieve the desired cutting or crushing effect.

3, high efficiency: especially the mining of mining materials, less damage, the finished product rate can be increased 2-3 times.

4. Economics: The cost of using breakers is much lower than other crushing and cutting Tools.

5, the use of simple: just mix this product with a fixed amount of water and stir into a uniform slurry, then pour into the drilled hole.

6, safe and convenient transportation.

The use of static blasting agent precautions:

1. From the time of grouting to the cracking of an object, in order to avoid damage to the “spray hole” of the breaker, no one can directly look into the hole or place any other body part directly above the hole.

2, in the operation, need to wear protective glasses (to prevent eye damage when the breaker breaks), rubber gloves (to prevent skin from corrosion), masks (to prevent excessive inhalation of broken agents).

3. If the eyes are accidentally sprayed by the breaker, do not blink your eyes with hands. Rinse immediately with plenty of water and seek medical attention. When the skin comes into contact with the cracking agent, rinse it with water.

Static blasting agent storage note:

The product should be protected from moisture and sun exposure during transportation and storage. Avoid contact with children. Please use immediately after opening. If it is not used up at one time, the bag should be tightly closed immediately and it must be opened again when it is needed.
