Beijing time March 17 news, researchers have recently developed a world's darkest material, can spray with a spray gun, this material called Vantablack S-VIS can absorb 99.8% of the light, the reflective ability than Kazakhstan The ultra-black paint used on the Bosch Telescope is also 17 times weaker. This new material can easily cover the surface of large, complex structures such as large cameras and aircraft. Vantablack S-VIS's previous generation material, Vantablack, was made from low-temperature carbon nanotubes and was successfully developed in 2014. "Vantablack's nanostructures can absorb almost all incident light, allowing precise optics to perform at their best," said Surrey NanoSystems, a British company that developed the material. According to the company, this material absorbs 99.956% of incident light. “The initial Vantablack paint has been a milestone and has played a crucial role in many companies that develop high-performance equipment,†said Ben Jensen, chief technology officer at Surrey NanoSystems. "And after further research and development, this new type of sprayable material has a greater scope of application." The improved version will be used in more areas. For example, in the field of aerospace, it can cover the surface of larger and more complex shapes and structures. "Unlike other light absorbers, this material has excellent performance at a variety of viewing angles and wavelengths, and this is critical for the appearance of optical instruments and many objects," the company said. After spraying this product, this black paint can make the 3D object look like a 2D plane, black hole, so that you can not see the details of its surface. Vantablack S-VIS used a carbon nanotube mixture in its development. There are many steps to perform before and after spraying to achieve an ultra-low reflectance. "Vantablack S-VIS is very effective. Its performance far exceeds any known ultra-black paint, and its reflectance is only 0.20%," said Janssen. “The scope of application of this material will include commercial products such as cameras, precision instruments that require improved performance, and the appearance of the product through the unique visual effects of such coatings. Compared to existing commercial light absorbing coatings, this New materials are a big step forward." The company stated that the spray should not be used where direct contact or rubbing can occur. Vantablack S-VIS is designed to protect objects that must be sealed or stored in specific glass and protective layers, and can only be used on fixed surfaces that can withstand high temperatures of 100 degrees Celsius. The customer can ask the company to spray Vantablack S-VIS for them, or they can apply for a license to use this coating in their own production equipment. The public can go to the Science Museum in London to see for yourself how dark this “world’s darkest paint†is. High Speed Door Motor And Control Box
Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.
About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.
About servo High Speed Door Servo Control System: Our rolling gate servo control system is suitable for high speed and high usage soft and hard rolling gate. The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: ＜16 ㎡; Daily operating time: ＞2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.
The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.
System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.
Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.
The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.
Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.
Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.
High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.
Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.
About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
