In 2014, the Nobel Prize in Physics was awarded to Japanese scientists Akasaka Akira, Amano, and Japanese-born scientist Nakamura Shuji, who was naturalized to the United States, in recognition of their outstanding contributions to the invention of the blue light-emitting diode. In the past, the light-emitting diode (LED) had red and green light, but it was not until the breakthrough of the blue-ray technology in the 1990s that it could be synthesized into a white light close to daylight, and then the lighting revolution brought about by the current LED was triggered. In the award-winning statement, the Nobel Prize Committee specifically mentioned the invention of LED lights, which will make a bright dream for the 1.5 billion people who have not connected to the power network. Because the power required to light the LEDs is very small, relying on It is enough to generate electricity from simple solar power. There are still 35 people in the world who are not stably integrated into the power grid. There are 7 billion people in the world, 1.5 billion are not connected to the power network, and there are more than 1 billion power networks unstable. Some can only supply electricity for several hours a day. This group of people we call energy poor people (EnergyPoverty), most of them in Africa, Southeast Asia and India. Without electricity, they must rely on daytime work, housework, water intake, and reading. Once in the evening, the family must rely on candles or kerosene to cook dinner, or to do family work. Use kerosene lamps and candles to read? Not only is it too extravagant, but the eyes will quickly fatigue. The indoors will be filled with exhaust gas after fuel combustion, which will inevitably have adverse effects on family health in the long run. There is no reading of electric lights, let alone watching TV to absorb domestic and foreign information, and using computers to access the Internet is even more delusional. In the new era of globalization and informationization, the most vulnerable group of these developing countries, their education has been left behind. The reason why the energy poor do not have a power network is that they are mostly remote or illegally inhabited so that they cannot obtain the basic facilities such as basic electricity. He may live in a partial settlement in Tanzania, or he may live in many slums in the Mumbai metropolitan area of ​​India. However, LEDs can reverse this situation. Portable LED Rechargeable Lights for the Masses India's largest women's group All India Women's Association (AllIndiaWomensConference) is based in the community, setting up a community solar charging station to charge portable LED lights during the day, and people renting lights when they get home from work. Provide night lighting at home for several days. Since the cost of solar panel construction is still a threshold, there is an opportunity to build a shared charging station through joint cooperatives or community fund-raising methods. Letting people rent lanterns is equivalent to selling electricity cheaply to those in need. More people can get it. Community women are trained to become equipment maintenance technicians and plan to earn compensation. Not only the All India Women's Federation, but also the Barefoot College, and many independent cooperatives are pushing similar things. The reason why solar lamps are widely promoted in India is that the well-known environmental think tank Teri in India has long promoted the plan to illuminate millions of people and successfully attracted foreign governments such as the British government. Of course, the price of solar panels has fallen sharply, and the emergence of LED lamps is the main reason for everyone to enjoy the bright future.
Rotary Tablet Press
Classification of tablet press: Models can be divided into single punch tablet press, rotary tablet press, sub-high speed rotary tablet press, automatic high speed tablet press and rotary core tablet press.
The sheet shape pressed by the tablet press is initially flat circular, and later developed into shallow circular arc and deep circular arc on both sides, which is for the need of coating. With the development of special-shaped tablet press, oval, triangle, oblong, square, diamond, circular ring tablets followed. In addition, with the continuous development of preparations, due to the requirements of compound preparations and timed release preparations, special tablets such as double layer, triple layer and core coating are made, which need to be completed on special tablet press.
Rotary tablet press is a machine which is made of several pairs of die distributed on the turntable to make a circular lifting movement according to a certain track and press the granular material into tablet through the press wheel. And the stamping rod with the rotary table rotating speed ≥60m/min line press is called high-speed rotary tablet press, this high-speed rotary tablet press has a forced feeding mechanism, the machine is controlled by PLC, has the automatic adjustment of pressure, control the weight of the piece, eliminate the waste piece, print data, display fault shutdown and other functions, in addition to the control of the weight difference within a certain range, Quality problems such as missing Angle and loose lobe can be automatically identified and eliminated.
With the development of market demand, the scope of application of tablet press is more and more wide, no longer simply limited to the suppression of Chinese and Western medicine tablets, more widely suppressed health food, veterinary medicine tablets, chemical tablets: such as mothballs, washing blocks, smurf blocks, art powder, pesticide tablets, food tablets: chicken essence block, isatis root block, divine Qu tea block, compressed biscuits.
