The barium tungsten electrode used in electropulse sterilization equipment is a high-performance electrode material. Its core advantages lie in the combination of tungsten's high melting point, corrosion resistance, and barium's low work function characteristics.
I. Application Principles of Barium Tungsten Electrodes in Electropulse Sterilization Equipment
Barium tungsten electrodes are primarily used to generate high-intensity pulsed electric fields in electropulse sterilization equipment. Instantaneous high-voltage pulses directly disrupt the cell membrane structure of microorganisms, causing leakage of cellular contents and subsequent death. This non-thermal sterilization technology is particularly suitable for heat-sensitive liquid foods (e.g., fruit juices, milk), avoiding the nutrient degradation caused by traditional thermal sterilization.
II. Performance Advantages of Barium Tungsten Electrodes
1. High Current Density and Uniform Discharge:
The work function of barium tungsten electrodes is as low as 1.6 eV, with a current density exceeding 10 A/cm2. This ensures stable generation of high-intensity pulsed electric fields and uniform discharge, guaranteeing consistent sterilization efficacy.
2. Erosion Resistance and Mechanical Strength:
The high hardness of the tungsten matrix and barium doping enable excellent erosion resistance during high-frequency pulsed discharges, significantly extending equipment service life.
3. Corrosion Resistance and High-Temperature Stability:
Barium tungsten electrodes exhibit corrosion resistance in electrolytic environments and can withstand high-temperature, high-humidity conditions, making them suitable for complex industrial scenarios.
III. Application Fields of Barium Tungsten Electrodes in Electropulse Sterilization Equipment
1. Food Industry: Non-thermal sterilization of liquid foods, such as juices and dairy products.
2. Medical and Pharmaceutical: Pulsed electric field-assisted sterilization for sterile production equipment.
3. Water Treatment: Microbial inactivation in water bodies via electropulse technology to improve water quality.
