High Temperature resistant fire sleeve widely serves in petrochemical industry
In the industrial production, an anti static duct hose is necessary. It can both deliver the raw material and transport the scrap. However, there are 2 kinds of such hose which look the same. Thus you may feel confused about them. Then how to identify them? Let me introduce you next.
One kind of PU static conductive hose uses static conductive agent mixed with PU raw materials. The walls of the produced hoses have static conductive properties. This wear resistant conveying hose has is similar to stainless steel hoses. The pipe wall can conduct static electricity. Then it neutralizes the static ions generated by friction during the material transfer process in the hose. This prevents material clogging and static accidents caused by static.
Structure: The pipe wall has steel wire spiral, and the inner wall of the pipe is smooth.
Material: pipe wall PU, spiral wire
Another type of anti-static hose has a ring of steel wire wrapped around the middle of the hose wall. Because steel wire is a good conductor, it can quickly conduct static. Thus it plays an anti-static role. When it transports abrasive materials, separation of positive and negative charges will occur due to mutual friction between material molecules. Since the pipe wall is insulated, the electrostatic ions generated can not be removed from the pipe wall in time. The large amount of static ions will produce positive and negative charges at both ends of the hose. As a result, it causes block to the.
To eliminate the generated positive and negative charges, the electrostatic ions at both ends of the hose need to be directed away. Guide it or connect it through wires to neutralize the positive and negative charges. At this time, the steel wire on the inner wall of the hose can quickly neutralize the ions at both ends through the connecting stainless steel at both ends.
