Hubei Economic and Trade Delegation visits Taiwan with a $1.5 billion purchase order

The provincial economic and trade delegation will visit Taiwan on April 19. The Hubei delegation will be led by Luo Qingquan, secretary of the provincial party committee, and will lead about 3,000 people to visit Taiwan.

This time, the Hubei delegation is expected to purchase about 1.5 billion US dollars in Taiwan, but the possibility of overweight purchase is extremely high.

Taiwan’s foreign trade association officials said that the procurement project of the Hubei delegation in addition to agricultural products, people’s livelihood supplies, and pharmaceutical machinery, in response to Hubei’s industrial goal of building China’s Optics Valley, will also include LCD panels. Electronic components such as LEDs.

Piezoelectric Ceramic Ring 



Applications: ultrasonic vibration tranducer for inkjet printer 



Vibration mechanism of inkjet printer: 

Generally, it is composed of piezoelectric ceramics and driving rods. By high-frequency electric excitation, piezo ceramics produce high-frequency ultrasonic vibration (above 60 kHz or higher), which is transmitted to the driving rod and generates high-frequency micro-displacement (back and forth expansion) at its front end.

Piezo ceramics components features :

1. High vibration amplitude and can withstand higher power.
2. The product has high reliability, strong maintainability, and is not easy to break down or off-line.
3. The frequency can be adjusted in a wide range, generally within the range of 10KHz.
