Continuing from Stage 4 of our research, we proceeded to design, fabricate, and test the test tubes intended for injection in a three-stage vacuum suction cycle until reaching 0.1 micro atmospheres of pressure. Subsequently, the tubes were subjected to gas injection and sealed at nano atmospheric pressure. The three stages are as follows: Vacuum suction to reduce pressure to 0.1 micro atmospheres. Gas injection into the test tubes. Sealing the tubes at nano atmospheric pressure. #ResearchDevelopment #ExperimentalDesign #VacuumTechnology #GasInjection #PressureControl #AdvancedFabrication #ScientificInnovation

High quality specialty gas--Tetrafluoromethane (CF4) is a large amount of plasma etching gas in the microelectronics industry, which is widely used in the etching of silicon, silicon dioxide, silicon nitride and phosphorus silicon glass materials. It is also widely used in surface cleaning of electronic devices, production of solar cells, laser technology, low temperature refrigeration, gas insulation, leakage detection agent, control of space rocket attitude, stain remover, lubricant and brake fluid in printed circuit production. Due to its strong chemical stability, CF4 can also be used in metal smelting and plastics industries. Nowadays, the characteristics and development trend of electronic gases used in ultra-large scale integrated circuits are ultra-pure, ultra-clean and multi-variety and multi-scale. In order to promote the development of domestic microelectronics industry, countries are paying more and more attention to the development of special electronic gas production technology. CF4 has long occupied the etching gas market with its relatively low price, so it has broad development potential.#plasnaetching #surfacecleaning #refrigeration

UPVC valves are widely used in the semiconductor industry due to their excellent corrosion resistance and chemical stability. Semiconductor fluid systems must be able to operate stably in an extremely clean, corrosion-resistant and highly precise environment to ensure the efficiency and product quality of semiconductor manufacturing. YNTO's plastic valves are made of high-quality anti-corrosion UPVC material,mounted to pneumatic or electric actuators that can accurately control the system. This can ensure smooth opening and closing of the fluid system,accurate adjustment of the flow and changes of the flow direction. #UPVCvalve #electricvalve #pneumaticvavle #semiconductor #fluidsystem #flowcontrol #plasticvalve #pipework #anticorrosionvalve

#Optical_Pyrometer #Heattreatment 👇 An optical pyrometer is a device used to measure high temperatures by analyzing the thermal radiation emitted by an object. Unlike contact thermometers, which require physical contact with the object, an optical pyrometer measures temperature from a distance. The basic principle involves detecting the intensity of radiation from the object and comparing it to a known reference source. The device typically has an optical system that filters the radiation to a specific wavelength and a photodetector that converts the radiation into an electrical signal. The temperature is then inferred from the intensity of the detected radiation. Optical pyrometers are particularly useful for measuring temperatures in environments where physical contact is impractical or impossible, such as in furnaces, molten metal processing, or other high-temperature industrial processes.

🔬 Exciting Research Alert! 🔬 I am super excited to share some fascinating insights about surface structural changes in silicone rubber due to electrical tracking. 🌟 Silicone composite insulators play a crucial role in electrical power transmission and distribution. However, they are susceptible to degradation caused by electrical and environmental stresses. Understanding the degradation mechanism is key to preventing potential failures in the electrical grid. 🛡️ Through in-depth analysis using ATR-FTIR spectroscopy and 2D-COS techniques, we have uncovered remarkable findings. 📊🔍 We observed significant changes in silicone rubber samples from insulators during tracking wheel testing. These changes include a decrease in absorbance of different infrared (IR) bands, which represent various functional groups. This decrease in absorbance indicates the progression of degradation. Additionally, we noticed a simultaneous increase in surface roughness, which correlates with electrical tracking. ⚡ These findings have profound implications for the industry, as they enhance our understanding of the degradation process and enable us to develop strategies to mitigate potential risks. 💡 By implementing preventive measures based on this research, we can ensure the longevity and reliability of electrical power transmission and distribution systems. I am grateful to have collaborated with a team of brilliant researchers on this project, and I would like to extend my appreciation to our valued partners and supporters. Together, we are making significant strides in advancing the field of electrical engineering. 🤝 If you're interested in learning more about this research or discussing potential collaborations in the field, please feel free to reach out.

There are times when electrochemists need to experiment with working electrodes that are intrinsically grounded (e.g., for water pipes, rebar in concrete, etc.). There are also situations where the electrochemist needs to ground the counter electrode or ground the cell body of their electrochemical setup. This blog post highlights these different grounding configurations and discusses their relevant applications.
