Silent expansion agent is a powdered high-efficiency and safe crushing material for the safe removal of concrete structures and mining of cut marble and granite. The HSCA is adjusted into a slurry and poured into a rock or concrete borehole with water. After 3 to 8 hours, the crushing or cutting operation can be carried out without vibration, no dry sound, no flying stone, and no harmful gas. This product has been widely used for many years. What should we pay attention to during the use?
1. Wear protective glasses when handling the silent expansion agent, and read the operating instructions carefully.
2, do not close to the eyelet 2 hours after grouting, not to see at a close distance
3. It is forbidden to pour into the hole when the silent expansion agent is heated (hot air), and should be poured out of the barrel immediately.
4. Once you find that the hole is hot, please leave immediately.
5. The staff should be marked after grouting to prevent nearby personnel from entering the place.
6, pay attention to the safety of the stone after the expansion and cracking
7. If it is sprayed, please rinse it with plenty of water in time, do not lick, and seek medical attention immediately.
Operation steps: drilling – mixing – pouring – cracking
