#Carbon Dioxide Blasting Technology# Since its introduction to China in the 1950s, it has been highly valued and developed. Initially, it was specifically designed for coal mining in high-gas mines. Due to its safety, practicality, and convenience, it was quickly applied in industries such as cement crushing and mining. With the continuous development and improvement of the technology, it has been widely promoted and applied in fields such as mining, tunnel engineering, municipal engineering, and underwater blasting in many countries, especially in Europe and America. The introduction of this technology in China has been relatively lagging and conservative. To change this situation and accelerate the development of the national mining industry, we will continuously learn and develop new carbon dioxide blasting technologies to make them more mature. With the development of scientific practice, carbon dioxide blasting will undoubtedly usher in a groundbreaking revolution!

The Basic Principle of Carbon Dioxide Blasting Stone Tools:

Carbon dioxide blasting technology converts carbon dioxide gas into a liquid state under high pressure, which is then compressed into cylindrical containers (blasting pipes) using high-pressure pumps. Safety films, blasting plates, heat-conduction rods, and sealing rings are installed, and the alloy is tightened. The cap is ready for blast. The blasting pipes, detonators, and power cables are brought to the blast site, the blasting pipe is inserted into the drilled hole and secured, and the detonator is connected to the power source. When a microcurrent passes through the high-heat-conduction rod, the high temperature punctures the safety film, instantly vaporizing the liquid carbon dioxide and rapidly expanding to produce a high-pressure shockwave. This automatically opens the pressure relief valve, and the blasted object or sediment is subjected to a 300MPA shockwave and rapidly expelled outward. The entire process, from start to finish, takes only 0.4 milliseconds and produces a visible large-scale rock blasting effect!

Utilizing carbon dioxide blasting technology, the gas during underground blasting is diluted, with no vibration or dust. Carbon dioxide is an inert gas that is neither flammable nor explosive. The crushing process involves volume expansion, which is a physical work process rather than a chemical reaction.
