On February 10, 2015, the famous American technology magazine "Popular Science" announced the annual 100 best scientific and technological achievements, involving aerospace, engineering and construction, medical and health, software, hardware, entertainment, home, consumer electronics, sports. 12 categories of leisure, green, car, safety and so on. This selection has been in place for 27 years, and the selection of the top 100 scientific and technological achievements has turned to technological innovations that will lead the future and change the future. Among them, Kyocera Sapphire Shield's indestructible mobile sapphire screen was rated as one of the top ten latest technologies. A broken mobile phone screen is a naked ridicule for our lifestyle-dependent lifestyle. A recent survey found that one in every four iPhones had a bad screen. In 2014, Kyocera released the first ultra-sturdy mobile phone screen that never broke. The Sapphire Shield screen is made from laboratory-synthesized sapphire, one of the hardest substances on the planet. The safe fall height of a sapphire screen is twice that of a normal screen. In addition, it is almost impossible to be scratched.
As an important technical crystal, sapphire is widely used in military, aviation, electronic consumer products, etc., sapphire applications have broad prospects, especially in the field of electronic consumption and LED substrate applications, whether this award can accelerate the development of sapphire What? Can it bring 100% or 200% growth in the industry?
Sapphire development status
With the advancement of sapphire growth technology and the continuous reduction of production costs, in addition to the application of LED epitaxial substrates in the past, sapphire has been widely concerned by various industries in recent years, and all countries in the world are optimistic about sapphire substrate business opportunities. Sapphire substrates are mainly used in the production of LED wafer materials, with high hardness, high dielectric constant, high thermal conductivity and other superior features, in addition to applications in smart phones and wearable devices, including Apple, Samsung, LG and other high-end In addition to the camera lens cover and main screen keys of smart phones, sapphire substrates are expected to be used in optical, aerospace and military applications.
From the application of current sapphire materials, LED application demand is expected to consume 2 to 3 million pieces per month on average, and with the popularization of high-end mobile phones and tablet lenses, home button applications, and next year's Apple watch market, sapphire The application of the material is becoming wider and wider. At present, the main reason for the low-lying sentiment of sapphire materials in the market is still the bankruptcy of GTAT. Investors believe that the reason for the sapphire's failure in this stage is the problem of technology and cost control, but in the long run, as long as there are new fields of application. The possibility that the process, technology, cost and other issues of new material production will be gradually digested over time. At present, it may be early to predict whether sapphire will actually be applied to the next-generation Iphone panel, but it is still worthy of attention from the perspective of the new material industry chain.
Sapphire future demand trends
With the promotion of sapphire in the Apple product chain and other smart phones, the demand for sapphire will increase in the future. In 2016, the sapphire application market will add nearly $2 billion in space, which will be more than three times the market for LED substrate materials. The future demand of Sapphire is mainly reflected in the following aspects:
Application areas of sapphire: 1, LED chip substrate material; 2, consumer electronics: camera, fingerprint identification cover, cover glass; 3, military; among them LED and consumer electronics applications occupy the vast majority of the industry's needs.
LED chip substrate materials in the future global application demand in the 60-80 million pieces (2 inch film), demand remains stable, consumer electronics is currently mainly used in mobile phone cameras and fingerprint recognition, if the demand for sapphire cover glass can be opened, the industry is still expected There is twice the room for growth.
According to industry research institutes, smartphones will grow at an average rate of 11.5% in the future. In 2018, shipments will reach 1.8 billion units, and the penetration rate of cover plates will reach over 20%, with demand exceeding 400 million pieces. If calculated at the price of 10 US dollars / piece, the industry size will reach 4 billion US dollars.
As the advantages and disadvantages of the mobile phone cover glass, sapphire has a high hardness (close to diamond), ultraviolet, infrared sapphire has advantages (for military), dielectric constant, crystal, more than amorphous. However, sapphire also has a low transmittance and a high density.
The industry believes that although the current proportion of non-LED applications in sapphire applications is less than 30%, but in the future with more consumer electronics using sapphire materials, its proportion will increase rapidly, it is expected that by 2016, the proportion of non-LED applications can be The proportion of LED applications is courtesy. At present, there are 148 sapphire manufacturers worldwide, 74 in China, and 39 have actual manufacturing capabilities. Although the bankruptcy of GTAT has affected the development of the industry, Apple has opened up the sapphire development space. The use of Apple's product chain and other smart phones is expected to increase demand for sapphire in the future. At present, many companies are preparing for sapphire materials in secret. For example, Luxiao Technology, Dongjing Electronics, Orient, and Lida Optoelectronics have already adopted various methods to make layouts for the sapphire market. It is reported that Apple will be in the next generation of mobile phones. With sapphire materials, the future development of the sapphire industry is huge and explosive.
Aluminum Spiral High Speed Door
The Spiral door offers high-speed operation for high-traffic situations and rigid aluminum slat construction that eliminates the need for a second security door. Crisp lines give the Spiral door a stylish look that's great for many types of commercial, automotive retail, government, institutional and industrial applications. The Spiral is ideal for automotive dealerships, government, parking and security. Benefits No metal-to-metal contact reduces wear on the door panel and offers fast, quiet operation.
Aluminum spiral High Speed doors are usually used wherever goods traffic occurs and where the doors have to fulfill special requirements. In the food and beverage industry, or Medical industry for example, special climatic conditions have to prevail; short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.
