TPU wear-resistant anti-static hose production process and working principle of electrostatic discharge
Nowadays, most of the static discharge hoses commonly used in the industry are made of polyurethane. Generally, there are copper wires or static conductive agents in the middle of the pipe wall, both of which can eliminate the static electricity generated by the materials in the pipe wall. TPU plastic rib anti-static hose is generally made of TPU and high-strength plastic ribs. It has light weight, softness, good elasticity, corrosion resistance, hydrolysis resistance, high transparency, non-toxic and odorless, small bending radius, good negative pressure resistance, and can maintain its original shape under vacuum. It can also maintain good flexibility at extremely low temperatures, with ultra-high strength and long service life. The tube wall is equipped with high-quality copper wires to eliminate static electricity.
There is a layer of copper wire in the middle of the pipe wall. Because copper wire is a good conductor, it can conduct static electricity quickly and effectively, thus playing a role of anti-static. When transporting some wear-resistant materials, due to the friction between the material molecules, the positive and negative charges will be separated. This is the electrostatic ion often referred to. Since the tube wall is insulated, the generated electrostatic ions are It cannot be removed from the pipe wall in time. The accumulation of a large number of electrostatic ions for a long time will generate positive and negative charges at both ends of the hose, which will cause the transportation of materials to be blocked.
To eliminate the positive and negative charges generated, the electrostatic ions at both ends of the hose need to be exported, guided to the ground or connected by wires to neutralize the positive and negative charges. At this time, the copper wire on the inner wall of the hose can quickly neutralize the ions at both ends through the connecting stainless steel at both ends. Ensure the normal transportation and circulation in the pipe wall. The anti-static and wear-resistant conveying hose with copper wire is a common static conveying hose commonly used in the industry.
