When we mention the use of diamond, we should think of making abrasive tools. In fact, it has a wide range of applications, friends, come and have a look~In addition to being an abrasive, 17 applications of diamond part 1
1. Application of diamond film in new technology of water treatment
In June 2008, the Spanish city of Zaragoza (Zaragoza) held a world expo with the theme of "Water and Sustainable Development". Germany showcased its sustainable water treatment innovations and ideas. They use diamond thin-film electrodes to purify drinking water. Visitors can start a crank generator (a Condias technology), a spark ignites the diamond electrodes, and the oxidation process begins, which initiates the purification process. Use electrodes to remove harmful organic substances in water without using any chemicals at all. This method effectively avoids undesired substances such as pesticide or drug residues in drinking water. Experts see this as a promising and innovative approach.
2. Diamond is expected to become the strongest laundry detergent ever
This is a research result initiated by the British Engineering and Natural Sciences Research Council and the Procter & Gamble Group, and the University of Warwick and Aston University. Dr. Andrew Marsh of the University of Warwick said: "Consumers need to wash their clothes about 80 times in 60 to 90 degrees Celsius water every year, just to remove the grease from the clothes. Our research can allow people to wash their clothes in cold water. It can easily solve the oil problem. Even in the water temperature as low as 15 degrees Celsius, these nano-sized diamonds will easily wash away the oil. Its physical and chemical principles can lay a solid foundation for future research."
In addition to being used as a decorative embellishment, diamonds may soon have another skill-laundry, becoming a veritable friend of the housewife. British scientists recently discovered that adding some diamond particles to washing powder (the diameter of a diamond nanoparticle is about 1/100,000 of the diameter of your hair), the decontamination effect will be increased several times, and the improved washing powder is effective against stubborn Works great on stains, especially oil stains. Researchers believe the discovery could help solve the problem of pesky oil stains in the laundry -- at least less expensive than buying a new garment.
3. Diamond enters the global water jet cutting field
When the application of waterjet cutting has grown significantly, users have put forward higher requirements in terms of improving equipment productivity and shortening the time for replacing parts, which promotes the development of diamond waterjet cutting knives. The industrial application of high pressure water cutting technology is very extensive. It can be used to cut chocolate, steel, paper, plastic, wood, granite and other materials. The growth of its application stems from its fast, flexible, accurate, green, cost-effective and other advantages.
Compared with sapphire, the service life of diamond tips can be extended by 15 to 20 times. Experiments have confirmed that after 1000 hours of processing using pure water under a pressure of 3500 Pa, the cutting quality of the water jet and the amount of water used are basically unchanged. Similarly, after 100,000 cycles of water cutting experiments with abrasives, both the quality of water cutting and the amount of water used have no change.
4. Diamond UV sensors are used in fire detection systems
Unlike traditional sensors that detect heat and smoke in the early stages of fire development, this new type of ultraviolet detection fire sensor uses a brand new technology that Quickly spot fires before they reach the dangerous stages of heat and smoke.
This new detection system consists of a sensor and an alarm device. The ultraviolet light sensor of this system uses a synthetic diamond film window material specially developed by NIMS. In addition, this new detection system not only has a faster response time than conventional sensors, but also has advantages in terms of power consumption and size.
The diamond ultraviolet sensor only needs a 9V dry battery to operate, and the diamond ultraviolet photosensitive device has a long service life and low energy consumption. Through comparison, it can be seen that the traditional fire detection system uses a vacuum tube photoelectric cell, and its normal operation requires a voltage of more than 300V, so the device consumes a lot of energy. In addition, the traditional sensor is large in size and easy to be damaged. On the contrary, the new diamond UV sensing device is compact (8×5mm) and has good impact resistance.
5. New generation of diamond tools to create the "King of Precision Machinery"
The new grating marking machine has superior performance, with a maximum marking area of 400mm×500mm and a maximum marking density of 6000 lines/mm, all of which are world-class. The precision mechanical system will also include the use of a multi-layer table structure that fully complies with the "Abbe principle", a load-bearing and guiding integrated quartz tool holder guide rail, a continuous switching technology for diamond tools in the middle, and a unique combination of continuous operation and intermittent marking. Many innovations such as working methods.
Speaking of the grating marking machine known as the "King of Precision Machinery", many people think it is very strange and far away from their lives. In fact, it is necessary for the grating to play a role in everything from space detection to blood sugar testing. The marking machine is the working machine for making gratings.
As the core component of the grating spectrometer, only with the new grating technology can new spectroscopic instruments be born and promote the rapid development of the entire spectroscopic instrument industry. The development of a large-scale high-precision diffraction grating marking machine will greatly improve the level of grating manufacturing in my country, promote the rapid development of the spectral instrument industry and spectral testing technology, and enhance the independent innovation capability of my country's precision machinery manufacturing industry.
6. Application of diamond in minimally invasive surgery
The Interventional Therapy Center of the Second Xiangya Hospital of Central South University successfully cured two patients with “porcelain” coronary heart disease with coronary atherectomy for the first time. The two patients showed their thumbs up to the doctor and said in gratitude: “You are really amazing, you really have diamonds, Don't be afraid of porcelain work."
Coronary atherectomy is a type of minimally invasive surgery. This operation is to send a catheter with a diamond grinding head to the calcified part of the coronary artery of the patient's heart. The grinding head grinds away the calcified part at a speed of more than 100,000 revolutions per second. The calcified debris is smaller than red blood cells. The debris will be gradually removed with the flow of blood throughout the body, opening up a channel for the blood flow of the patient's heart muscle.
