AI Technical Summary

Benefits of technology

This technology offers strength against permeable substances like water or gases that could damage equipment used for cooling systems such as air conditioners (ACs). It also provides excellent heat transfer properties at both very cold temperatures (30C) and extremely hot conditions with minimal sound levels during operation. Additionally it's effective when replacing metallic parts due its ability to absorb shock waves without losing their effectiveness over time.

Problems solved by technology

This patented describes how plasma chemical reactors have found applications in industries like electronics manufacturing where there exist several types of industrial processes involving production of precision products called electronic components. These include semiconductor devices, advanced ceramic systems, power supply equipment, medical instruments, and defense tools. However, despite its advantages over existing technologies, current methods cannot meet all three important needs simultaneously due to limitations associated with each component's properties.
