LED street lights of Shifu Zhenjiang Laonanxu Road officially lit
On the first day of January, at the beginning of the new year, the Zhenjiang market sent good news. The LED lighting project of the old Nanxu Road passed the acceptance inspection organized by the Zhenjiang Main Road Command and officially lit up. The main road office and technical department gave high praise to SFT-LED street lights, and determined that Laonanxu Road is the standard test road for Zhenjiang LED street lights. The bidding for the street lamp attracted many well-known domestic enterprises to register, and finally Shifu won the bid with high-quality products and reasonable solutions. The project was successfully completed and passed the acceptance test, which laid a solid foundation for the extensive use of SFT-LED products in the Zhenjiang market.
Yuhai piezo materials include : hard piezo material, soft piezo
material and lead free piezo material
Soft piezo
material exhibits: larger piezoelectric constants, higher permittivity, larger
dielectric constants, higher dielectric losses, larger electromechanical
coupling factors, low mechanical quality factors, a lower coercive field, poor
linearity, and is easier to depolarize. The ideal application of soft piezo materials is sensing needs. Yuhai soft
pizeo materials are PZT-5, PZT-5H, PSnN-5 and PLiS-51.
Hard piezo
material exhibits: smaller piezoelectric constants, lower permittivity, smaller
dielectric constants, lower dielectric losses, smaller electromechanical
coupling factors, high mechanical quality factors, a higher coercive field,
better linearity, and is harder to depolarize. The ideal application of hard piezo materials is high power transducer needs. Yuhai hard pizeo materials are PZT-4, PZT-8, PCrN-4 and PBaS-4.
Yuhai company developped lead free piezo material BaTiO3 and apply for the Chinese Patent in 2011, to meet the needs of environmental protection in today's society.
