Ultrasonic soldering iron equipment
Ultrasonic soldering allows the joining of different materials and can be used for difficult materials to solder by conventional methods. Since no flux is required, users can save time and costs in cleaning flux residue while reducing corrosion and increasing the soldered joint’s durability.
Ultrasonic atomization spraying equipment
Ultrasonic spraying uses only ultrasonic vibration energy to atomize. Ultrasonic atomizing spray equipment is considered “green” technology due to its low energy consumption and high efficiency, making it ideal for critical fluid applications.
Ultrasonic emulsification equipment
Ultrasonic emulsification is a process in which two or more incompatible liquids are mixed under the action of ultrasonic energy, with one liquid being uniformly dispersed in the other to form an emulsion-like liquid.
What are resonance and resonant frequency
The object resonates under the action of external force, and the frequency of this resonance is called the resonant frequency.
How to calculate frequency
Frequency is the number of times that periodic changes are completed per unit time, and is a quantity describing the frequency of periodic motion.
The difference between Young’s modulus and modulus of elasticity
Young’s modulus of elasticity is a physical quantity that characterizes the tensile or compressive resistance of a material within the elastic limit.
What is the modulus of elasticity
The axial stress ratio to the axial strain of the material in the elastic deformation stage is called the Modulus of elasticity.
Ultrasonic fabric cutting
The cutting process of fabrics is generally divided into cold cutting and thermal cutting, both of which have certain limitations. Compared to cold cutting, the edges of the cut edge are fused after the thermoplastic material has been cut using ultrasonic fabric cutting; Compared with the thermal cutting process, the use of ultrasonic cutting can make the edge of the fabric being cut very soft and avoid excessive edge thickening due to melt shrinkage. Since the ultrasonic waves are heated from the inside of the fabric, there is no fabric yellowing. Since the ultrasonic waves are heated from the inside of the material, there is no fabric yellowing.
What is Curie temperature and its influence on piezoelectric ceramics
Piezoelectric ceramics are sintered at the Curie temperature, f the temperature exceeds the Curie temperature,the piezoelectric ceramics will be depolarized
