According to a report from the Russian "Newswires" News Network on February 7, Canadian researchers published an article in the prestigious scientific journal "Nature," revealing that a microcrack system could potentially enhance the strength of glass by up to 200 times. This groundbreaking discovery has sparked interest in the field of material science.
To validate this theory, scientists conducted an experiment where they used a laser system to create tiny holes, just a few microns in diameter, in regular glass and then filled them with polyurethane. They found that while cracks in traditional glass often lead to breakage, introducing controlled microcracks could actually improve the material's strength significantly. This method allows the glass to absorb stress more effectively, preventing it from shattering easily.
The study also highlighted that these carefully placed microcracks cause the fracture edges to come together without further breaking the glass. Researchers compared this approach to the natural structures found in animal teeth and shells, which are known for their durability. Although the microcracks are visible now, the team believes they can be made smaller in future developments, making the technology even more practical.
In addition, in February 2013, physicists at Yale University proposed a theory about non-shatterable soft glass, explaining that the mechanical properties of materials are influenced by how quickly they cool down. This adds another layer to our understanding of how to manipulate the strength and flexibility of glass-like materials.
This ongoing research not only pushes the boundaries of material engineering but also opens up new possibilities for creating stronger, more resilient materials for everyday use. (Internship Compilation: Yan Huijun | Reviewer: Lie Man)
Features:
1. The internal structure is all modularized, which saves workers' wiring time and facilitates assembly, maintenance and replacement
2. The design of the internal interface board is convenient for on-site installation, and the shaft cable and the accompanying cable are connected directly, saving time and effort and avoiding wiring errors
3. Built-in overvoltage protection module, cut off the input power in time when the field neutral line is disconnected, and will not damage other modules of the system due to overvoltage
4. Built-in DC24V switching power supply, directly supply power for peripheral boards such as call ladder board, control panel board, etc. The rated output current can reach 5A
5. Because the transformer no longer provides power for the brake, the capacity is greatly reduced, the volume and weight are greatly reduced, and the light weight of the control cabinet is realized. The volume of the cabinet is reduced by 66% compared with the non-modular control cabinet.
6. Lightweight design of the whole cabinet, no wire troughs, the most simplified number of air breakers, contactors and card rails
