Water cutting only needs water and natural garnet, and no other substances are produced during the cutting process. It is a clean and environmentally friendly cutting process.
Nowadays, the whole world is advocating environmental protection, such as the most common environmental slogan "Let the earth rest for an hour", going out to take the bus, saving energy and reducing emissions, etc. A series of people have gradually realized the importance of environmental protection. In fact, industrial pollution accounts for a large proportion of pollution in today's society. The traditional cutting field also faces environmental protection problems. For example, the toxic gas of laser cutting requires a cutting tool that can maximize environmental protection and efficiency - water jet, Water jet cutter.
In recent years, the country's requirements for environmental protection have become higher and higher, and some regions have stricter requirements. Traditional cutting equipment has been unable to meet the requirements for environmental protection.
Although traditional water jet cutting machines have less impact on the environment, noise and abrasives in abrasive jets are two factors that affect the EIA.
For noise prevention and control, on the one hand, we have taken active noise reduction measures and related design upgrades in recent years, and on the other hand, we have adopted curtain partitions.
The modularization and standardization of the water jet adopts the acoustic detector to detect the noise intensity of the noise source and the phase of the acoustic wave, and then uses the acoustic transmitter to transmit the acoustic wave with the same intensity but opposite phase. After the two beams of acoustic waves are offset, the noise intensity can be reduced.
Abrasive jet cutting is indeed a good cutting process. In order to reduce its impact on the environment, one is to actively develop new forms of jet cutting, such as ice jet. It uses liquid carbon monoxide or liquid nitrogen to cool a jet of pure water, which produces fine ice particles as abrasive.
The second is to recycle the abrasive and waste water used by water cutting to achieve the purpose of environmental protection, and the waste water can reach the standard of direct discharge after being filtered. The treated abrasive can also be reused. Garnet abrasives are broken after use, and their particle size is reduced. After recycling, they need to be screened to screen out abrasives of different particle sizes, which can be reused.
Recently, there are also experiments using iron filings as cutting abrasives. Due to the high toughness of iron filings, they are not easily broken during collision with the workpiece, and the particle size does not change before and after use. It is easy to recycle and use, and it is economical. However, compared to traditional garnet abrasives, the price will be relatively high. Since the ice melts into water after cutting, it has no impact on the environment, so it is a very promising jet flow method. In a word, with the rapid development of technology, jet processing technology will definitely present a series of new development directions, which will replace the existing processing technology.
