Unidirectional Nano Film manufacturers take you to understand the application prospects of nano film materials

Author:


Unidirectional Nano Film manufacturers tell you that nano films are divided into dense films and granular films. A dense film refers to a film with a dense film layer, but the grain size is nanoscale; a granular film is a film in which nanoparticles stick together with extremely small gaps in the middle. Nano-membrane technology will gradually penetrate into various fields of science and technology, and change people's production concepts to a large extent. Several areas that nanotechnology will impact:

1. Lighting system
The semiconductors used to manufacture light-emitting diodes in lighting will gradually be produced in the nanoscale range. The efficiency of light-emitting diodes produced on the nanoscale is now comparable to that of incandescent light sources, because of their small size, durability and low heat generation. It will soon be widely used in aviation, automotive lighting, and general lighting.
2. Medical and biological fields
The manufacturer of Unidirectional Nano Film tells you that nanotechnology will approximately double the number of chemical substances suitable for pharmaceutical use; nanoparticles with a size of 50-100nm can be used to treat tumor sites, because larger particles cannot pass through the small pores on tumors. Nanoparticles can easily enter tumors through pores; nanotechnology will allow cancers to be detected at an early stage when only a few cancer cells are present.
Using the special optical and electrical properties of nano-film materials, countless new materials can also be developed. Nano-materials in the 21st century will definitely play a huge role in the fields of microelectronics, information, energy, environmental protection, aerospace and other fields. , to promote social development.
3. Tunnel plus attenuator
Considering some problems existing in the straight-through mode between tunnels, at present, in actual engineering design, an attenuator is tended to be added at the leaky cable connection in the middle of the tunnel to control the position of the handover point. This kind of scheme is based on the network optimization of the tunnel direct mode, and uses attenuators to shorten the range of effective coverage overlap. The manufacturer of Unidirectional Nano Film tells you that the difficulty of this solution is the value of the attenuator. If the attenuation value is too large, the signal at the middle point of the tunnel will be poor. If the attenuation is too small, the effective coverage overlapping range cannot be effectively shortened. Since the attenuator value selection will greatly increase the network optimization work, in projects that do not have strict requirements on the handover point, the leaky cable connection method of adding attenuators between tunnels is often not used.
4. Crossing method: crossing between tunnels
The manufacturer of Unidirectional Nano Film tells you that the signal at the leaky cable disconnection point is poor when the leaky cable is disconnected in the middle of the tunnel, and the network optimization is more complicated when the leaky cable is penetrated. At present, some system designers have proposed a new solution—— — Inter-tunnel crossing, that is, two leaky cables cross each other in the middle of the tunnel to create an overlapping laying area of ​​about 170 meters. In this way, it can not only ensure the smooth switching of mobile stations at the end of the overlapping laying area of ​​leaky cables, but also reduce network optimization work.
However, due to the high price of the leaky cable - about 100 yuan per meter, the use of tunnel crossing will greatly increase the construction cost. At present, no project has adopted this scheme. The manufacturer of Unidirectional Nano Film tells you that this scheme is still in theory stage, without actual engineering test.
