Hazard of static electricity

With the arrival of winter, dry air makes static electricity especially common. Although static electricity may seem insignificant, in some special environments, it can cause serious safety problems and even affect people's health.

01 Static electricity generation and hazards

It is very important to understand the causes and prevention measures of static electricity in winter.

Static electricity is a natural physical phenomenon, it is not static electricity, but the macro temporarily stay in a place of electricity. Matter is made up of molecules, which are made up of atoms, which are made up of negatively charged electrons and positively charged protons.

Under normal circumstances, the number of protons in the atom is the same as the number of electrons, positive and negative balance, so the external appearance of no charge phenomenon. However, when an atom is subjected to an external force, electrons may become deorbiting, leaving the original atom and invading other atoms, causing the atom to be charged. This unbalanced distribution of electrons is the cause of static electricity.

Static electricity in daily life is very common, such as when people stand on the carpet or sofa, the human body voltage can be as high as more than 10,000 volts, and the static electricity on the surface of rubber and plastic film can reach more than 100,000 volts.

Winter air humidity is low, making the static electricity on the surface of the object difficult to dissipate through air conduction, so that it is easy to accumulate a lot of static electricity. When static electricity accumulates to a certain extent, it will produce a discharge phenomenon, that is, the electric shock we feel.

Static electricity not only brings discomfort to people, but also may cause damage to electronic equipment. For example, static electricity may cause damage or failure of electronic equipment, affecting its normal operation. In industrial production, static electricity may cause fire or explosion, which poses a threat to safe production; In addition, static electricity will also absorb dust, affecting the cleanliness and quality of the product.

02 Working principle of the ESD masterbatch

In order to effectively prevent the adverse effects of static electricity, anti-static masterbatch came into being. Antistatic masterbatch is an additive specially designed to reduce the surface resistance of a material and prevent the accumulation of static electricity. It consists of carrier, antistatic agent and other additives, through high-speed mixing, extrusion molding, and then cut into granules.

One of the main components of the antistatic masterbatch is a conductive agent, such as carbon black, metal powder or conductive fiber, which can significantly improve the electrical conductivity and antistatic properties of plastic products when mixed with resin carriers.

The preparation method of antistatic masterbatch is usually to mix the conductive agent with the resin carrier, melt mixing, extrusion and granulation at high temperature. The resulting masterbatch can be added directly to the plastic for processing. The use of anti-static masterbatch can not only avoid electric shock, spark and other problems caused by static electricity, but also effectively prevent dust adsorption on the surface of the plastic, and improve the appearance quality and performance of the product.

Antistatic masterbatches work by reducing static buildup by releasing charge or increasing electrical conductivity. When the anti-static masterbatch is added to the plastic product, the conductive agent will form a conductive network inside the plastic, so that the electrostatic charge can be quickly conducted and released, thereby avoiding the accumulation of static electricity. In addition, the anti-static masterbatch also has good dispersion and stability, which can be evenly distributed in plastic products and maintain the anti-static effect for a long time.

03 Importance of ESD masterbatch

The importance of anti-static masterbatch in modern industrial production can not be ignored. First of all, it can effectively prevent the damage of static electricity to electronic equipment and ensure the normal operation and reliability of electronic products.

Secondly, in flammable and explosive environments, anti-static masterbatches can reduce the risk of fire or explosion caused by static electricity and improve the level of safety in production. In addition, the anti-static masterbatch can also reduce the dust adsorption on the plastic surface and improve the cleanliness and appearance quality of the product. It can effectively reduce the surface resistance of the material and prevent static accumulation.

The application field of antistatic masterbatch is very wide. In the textile industry, anti-static masterbatches can be used to produce anti-static fibers and fabrics, reducing the impact of static electricity on clothing and household items. In automotive manufacturing, aerospace and other fields, anti-static masterbatches also play an important role in improving the antistatic performance of components and ensuring the stable operation of equipment. Its main characteristics include: good compatibility anti-static masterbatch has good compatibility with resin, easy to add in the production process. The high-efficiency antistatic effect can make the surface resistance of plastic products reach 107-1011Ω, which meets the requirements of anti-static packaging materials. The antistatic effect is durable and will not fail rapidly due to time and environmental changes. Safety does not contain any toxic substances, meets FDA standards, and is harmless to humans and the environment.

Ruizer antistatic masterbatch is more easily dispersed than the previous direct addition of liquid, powder or paste antistatic agent to achieve the ideal antistatic effect.

The antistatic masterbatch is resistant to high temperature, has good performance, and will not decompose during spinning or injection molding. The addition amount is low, the effect is fast, and the effect is lasting. According to the processing characteristics of different resins, different high-efficiency antistatic agents are selected to meet the requirements of various processing industries.
