The vast expanse of space, starry, attracting people's attention since ancient times, bringing endless imagination; space and deep incomparable, vertical and horizontal radiation, open against the backdrop of hidden murderous, difficult to ascend through the ages. As more and more people put their eyes on space, how to make fiber-based technology that changes human society on the ground into space has also become a hot spot for many scientists.
Ordinary optical fiber due to doping problems in space applications have greater difficulties. Because of its novel characteristics, photonic crystal fiber has become the development direction of optical fiber technology in space applications. In order to realize the application technology of photonic crystal fiber in space, FiberHome and its flagship Ruiguang ICT Company carried out the technological innovation of the polarization-maintaining photonic crystal fiber and focused on the project of "135 micron fine-graded polarization-maintaining photonic crystal fiber".
After many years of hard work, the project team put forward a new type of polarization-maintaining photonic crystal fiber structure, and developed many technologies such as narrow temperature field high temperature furnace, precise lattice arrangement, fine micropore control and deuteration and anti-radiation, etc. Innovative development of 135 micron polarization-maintaining photonic crystal fiber solves the difficult problem of low loss and anti-radiation compatibility. The loss of 1550nm reaches about 1dB / km, which is the world's lowest recorded attenuation of photonic crystal fiber. At the same time, innovative design 135 micron size, can fully meet the high-precision fiber optic gyro and miniaturization development needs. On this basis, the application unit developed a high-precision photonic crystal fiber optic gyro and successfully implemented the first space application on the day boat No.1 in April 2017, opening the door to the application of photonic crystal fiber in space.
Innovation is the source driving force for the sustainable development of enterprises. Fiberhome made pains to innovate in the technological innovation of optical fiber and cable, dared to think that the predecessors did not dare to think and made predecessors afraid to do so and succeeded in realizing a series of innovations in optical fiber research. Adhering to more than 40 years Fiberhome technology research and development of FiberHome, Richter Communications will adhere to innovation-driven and hold high the banner of our country's high-end fiber optic cable innovation banner, in-depth research and development of PM fiber, Ytterbium fiber, energy fiber and rare earth-doped photonic crystal fiber And other series of practical technology for photon technology to better serve the community contributed to the beacon of power fiber!
Hydrogenated Nitrile Rubber O-Rings (HNBR)
Highly Saturated Nitrile Green O-rings in 70 durometer. Hydrogenation of nitrile rubber removes most of the residual unsaturation in the polymer to make it far less vulnerable to attack by heat, ozone, and oxygen. In fact, due to superior oil and temperature resistance, Highly Saturated Nitrile can sometimes be substituted for more costly fluorocarbon rubber. It is frequently used in automotive air conditioning systems employing R-134a refrigerants. It exhibits good resistance to petroleum based oils, compression set and a variety of Freons.
The Hydrogenated Nitrile Butadiene Rubber (HNBR) O-ring has quickly grown in importance over the last years, due to its excellent cost-performance balance and use in highly demanding applications such as automotive, industrial applications which require high performance.
HNBR O-ring meets higher temperatures than standard NBR
The HNBR O-ring has recently been developed to meet higher temperatures than standard NBR while retaining resistance to petroleum based oils.
HNBR O-ring has excellent resistance to oils and chemicals
Obtained by hydrogenating the nitrile copolymer, the HNBR O-ring fills the gap left between NBR, EPDM and FKM elastomers where high temperature conditions require high tensile strength while maintaining excellent resistance to oils and chemicals.
