Disposable chemical expansion tube blasting is a safe, environmentally friendly and economical blasting technology, which is widely used in various engineering fields.
The principle is to use liquid carbon dioxide to produce a high-pressure gas for blasting after being heated and expanded. Compared with traditional pyrotechnic blasting, this technology is safer, more environmentally friendly and more economical.
In the single-use chemical expansion tube blasting process, liquid carbon dioxide is injected into a special blast tube, and then the carbon dioxide is heated and expanded by heating, generating a high-pressure gas to push the piston inside the tube, and finally push the material at the other end of the piston out.
Due to the increase in volume after the gasification of carbon dioxide, the pressure of the gas produced is very high, which can reach thousands of pascals, making the blasting force very powerful.
Compared with traditional pyrotechnic blasting, disposable chemical expansion tube blasting has the following advantages:
1.Safety and environmental protection: Carbon dioxide is an inert gas, which will not react with other gases in the air during the release process, nor will it produce toxic and harmful substances, so it will not cause harm to the surrounding environment and personnel.
2.Disposable chemical expansion tube blasting does not require explosives approval and transportation like traditional pyrotechnic blasting, nor does it require professional operation, so the cost is low.
3.Simple operation: The blasting of disposable chemical expansion tube only needs to inject liquid carbon dioxide into a special blasting tube, and then the blasting can be completed by heating, which is simple and easy to operate.
However, there are also some limitations to the blasting of disposable chemical expansion tubes, such as the inability to be used in underwater operations and the high requirements for explosives. In addition, due to the extremely low temperature after carbon dioxide vaporization, this blasting method is not suitable for some substances that need to be kept at temperature.
In short, disposable chemical expansion tube blasting is a safe, environmentally friendly and economical blasting technology, which is suitable for a variety of scenarios, especially some situations where the use of traditional pyrotechnics needs to be avoided.
