teflon This F-C bond molecular formula makes it more reliable than other chemicals, and its friction coefficient can reach 0.04, which is also a commodity with very small friction coefficient among all chemicals. In the planning and design of stair building, the design staff thought of how to use the suitable raw materials of sliding bearings for stairs, and then chose PTFE board 。 Teflon board for stairs is the regulation of social and economic development. With the rapid development of social economy and technological progress in recent years, China has become more and more prosperous, and more consideration has been given to the potential safety hazards of ordinary people. Sometimes it is impossible to predict the adverse effects of earthquake disasters, and various prevention concepts are further strengthening. The formulation of PTFE for stairs is to ensure the effectiveness of stairs as a safety exit when an earthquake is coming. We all know that the elevator car is not allowed to take the multi-storey building when the earthquake is coming, which is also known to all. When the disaster is imminent, the stairs become the choice of most people to deal with emergencies. The PTFE board used for the stairs does not vibrate strongly with the main building or the earth at the same working frequency, thus reducing the destructive effect of the earthquake on the stairs, However, the stairs become a sliding support by using the small friction coefficient of the polytetrafluoroethylene board itself in the vibration, and then the stairs will collapse after a delay before the house suffers a small vibration or collapse, which gives an opportunity for escape and improvement.

Polytetrafluoroethylene board has been known to have high lubrication performance, high percentage elongation, high compressive strength and high toughness in raw materials. Taking advantage of this feature, the shock isolation layer is set as the connection at the theme activity of the stair connection point. When the local shock wave returns, the theme activity can be carried out between the stairs and the stair board, thus preventing the driving force of the pendulum from loading on the stairs, leading to the rupture of the stairs and casualties. At the same time, the stair cushion block can quickly bear most of the kinetic energy of the seismic wave to achieve conversion, consume the effect of seismic fluctuation kinetic energy on the stair structure, and reduce property losses to a large extent. In case of an earthquake, the rolling staircase can be regarded as a separate module, and some small amplitude vibration, rather than strong vibration with the main building or the earth, can reduce the destructive effect of the earthquake on it, ensure that the safety exit is unobstructed in case of an earthquake, and make the staff withdraw immediately.
