View the necessity of electrostatic protection through the hazards of static electricity

Static electricity exists all the time in life. It mostly occurs in autumn and winter. At this time, the climate is dry and it is easy to produce static electricity. We usually Static electricity is indifferent, but everyone knows that it is these static electricity that can bring devastating disasters.

Relevant experts have done a test: rub a glass rod on a chemical fiber cloth 20 times, and immediately use an instrument Measurement results show that the high voltage can reach 15,000 volts. Pure polyester clothing can generate a high voltage of 50,000-100,000 in an instant. Static electricity has a certain degree of harm to the human body. When the static electricity voltage reaches 2000 volts, people will feel it in their fingers; when it exceeds 3000 volts, sparks will appear and there will be a pinprick-like pain in the fingers; when it exceeds 7000 volts, people will get electric shocks. feel.

A person walking on the carpet will generate a large amount of electricity due to friction with the carpet. When he reaches out to pull the metal door handle, a spark discharge will occur between his hand and the metal handle (which has an induced charge on it). Gives people a feeling of electric shock. If such spark discharge occurs in factories and laboratories, it may cause fires. When an airplane is flying, if the electricity generated by friction with the air is not dissipated during the landing process, when the ground crew approaches the fuselage, a strong spark discharge may occur between the person and the airplane, which may knock people down in severe cases. Tank trucks specially used to hold liquid fuels such as gasoline or diesel. During the filling and transportation process, the oil and the tank will rub and impact and carry a large amount of charge. If it is not removed in time and accumulates to a certain extent, electricity will be generated. A spark ignites the liquid fuel causing an explosion. There have also been incidents of static sparks causing ether to explode on hospital surgical operating tables.

Through the above scientific experiments and case analyses, I believe you now have some understanding of the dangers of static electricity. So how to reduce and avoid such disasters. Detailed analysis is provided below.

Reducing the hazards of static electricity can start from the following two aspects. First, start from the root cause of static electricity, such as using anti-static materials in the workplace for laying and protection. This avoids the generation of static electricity. Second, when the problem of static electricity cannot be solved from a distance, we should start with human body contact with spinning cotton. The most common one is to wear anti-static work clothes. What needs to be noted here is that qualified anti-static work clothes need to be woven with anti-static fabrics that meet the national testing standard GB12014-2009. The ability to use this kind of fabric for finishing requires understanding of the protective clothing capabilities. Reduce the harm caused by static electricity.

The anti-static fabrics produced by Science and Technology are woven from imported conductive yarns and are divided into pure cotton, CVC polyester-cotton, moisture-wicking and sweat-wicking blended chemical fiber fabrics. And adopt the grid staggered method. It meets the requirements of the national standard GB12014-2009 “Antistatic Workwear” and is widely used in petroleum, chemical, electronics and other industries.
