A, the generation of static electricity

　　Static electricity is an objective natural phenomenon, generated in many ways, such as contact, friction, impulse flow, etc.. The basic process can be summarized as follows: contact → charge → transfer → coupling layer formation → charge separation. Human body due to its own actions and other objects in contact with the separation, friction or induction and other factors, can bring thousands of volts or even tens of thousands of volts of static electricity. Static electricity is the result of the loss of balance between positive and negative charges in the local range. It is a kind of electrical energy, retained in the object performance, with high potential, low power, small current and the characteristics of the short duration of action.

　　B, the main hazards of static electricity.

1, explosion and fire are the hazards of static electricity. Although the electrostatic energy is not large, but because of its high voltage and prone to discharge, electrostatic sparks. In the workplace with combustible liquids (such as oil transportation, etc.), may be caused by electrostatic sparking fire. In places where there are explosive mixtures of gases, vapors or explosive mixtures of dust fibers (such as oxygen, acetylene, coal dust, aluminum powder, flour, etc.), may be caused by electrostatic sparks.

　　2. Electric shock due to static electricity may occur when the human body is close to a charged object, or may occur when the body with an electrostatic charge is close to a grounded body. The degree of electric shock and the stored electrostatic energy, the greater the energy, the more serious electric shock.

　　3, in some production processes, such as the failure to eliminate static electricity, will hinder production or reduce product quality, for example, static electricity so that the powder adsorbed in the equipment, will affect the filtering and transport of powder.

　　4, electrostatic discharge can easily destroy the sensitivity of electronic components. For some transistors, a few hundred volts of electrostatic discharge can completely make it obsolete. For electrostatic discharge sensitive components are integrated circuits. Static electricity may also cause electronic components misoperation, so that some electronic computer class equipment work out of order.

　　C, the main measures of static control

The main measures of static control are: electrostatic leakage and dissipation, electrostatic neutralization, electrostatic shielding and grounding, humidification, etc.

　　D, Huili anti-static floor structure composition

　　Huili anti-static flooring has upper and lower steel plate stretching, spot welding forming, exterior spraying anti-corrosion; inner cavity filled with foam cement to enhance the mechanical load-bearing properties; floor surface paste with wear-resistant, fire-resistant, pollution-resistant, anti-static trimethylamine (HPL) panel, surrounded by inlaid PVC conductive edge strip.

　　E. Anti-static principle of Huili flooring

　　In the room, the staff wearing wool and fiber clothing or wearing rubber, insulating shoes walking back and forth, it is very easy to generate static electricity accumulation. The use of anti-static flooring, you can make the electrostatic leakage off.

　　Huili anti-static flooring is mainly used to make the principle of static electricity leakage and dissipation. National anti-static industry standard SJ/T10796-2001 anti-static activity flooring standard definition of anti-static: conductive type: system resistance ≤ 1 × 106Ω; static dissipative: system resistance in 1 × 106 ~ 1 × 1010Ω. Huili HPL veneer surface resistance 1 × 105 ~ 1 × 109Ω, surrounded by inlaid PVC conductive side strips, its resistance ≤ 1 × 105Ω. HPL and PVC side bar with conductive glue bonding, the formation of through body, flooring installation, PVC side bar resting on the metal beam, beam and bracket with screws, so that the floor and bracket are formed conductive, its system resistance in 1 × 106 ~ 1 × 1010Ω, the floor surface generated by the electrostatic through HPL → PVC side bar → metal beam, bracket → bracket → grounding wire and other channels dissipation leakage Off, the surface of the floor can not gather static electricity, thus playing the anti-static performance.
