Overview

A manufacturer of 5mm thick polytetrafluoroethylene plates with guaranteed quality. The tensile strength of polytetrafluoroethylene plates is 21-28MPa, the bending strength is 11-14MPa, and the elongation rate is 250% -300%. The message friction coefficient of polytetrafluoroethylene plates against steel is 0.04. The friction coefficient of 5mm polytetrafluoroethylene plates is smaller than that of nylon, polyoxymethylene, and polyester plastics. Currently, various types of polytetrafluoroethylene plates and polytetrafluoroethylene products have played a crucial role in the national economy in chemical, mechanical, electronic, electrical, military, aerospace, environmental protection, and bridge industries.

Product Details

Manufacturer of 5mm thick PTFE sheet Polytetrafluoroethylene is a material with a low coefficient of friction among known solid materials (much smaller than ice). At the same time, the production process of polytetrafluoroethylene plates requires a pressure greater than 30MPa, and the tensile strength of the product itself is greater than 15MPa (equivalent to the strength of C15 concrete in buildings) and the tensile rate is greater than 150%. Choosing polytetrafluoroethylene plates in this position is based on two points: excellent sliding performance, reliable strength, and strong tensile rate.
The purpose of designing sliding support structures for stairs is to ensure that in the event of an earthquake, the sliding stairs can vibrate as an independent unit with small amplitude, rather than violently vibrating at the same frequency as the main building or the ground, thereby reducing the destructive power of earthquakes on the stairs and ensuring that the passage is not first damaged and unobstructed, allowing personnel to evacuate in a timely manner.
Appearance of PTFE board:
1. The color of the board is the natural color of the resin.
2. The texture should be uniform, the surface should be smooth, and there should be no defects such as cracks, bubbles, delamination, mechanical damage, knife marks, etc.
3. Allow for slight cloud like looseness.
4. Allow no more than one non-metallic impurity with a diameter of 0.1-0.5mm and no more than one non-metallic impurity with a diameter of 0.5-2mm on an area of 10 × 10cm2.

Construction method of stair sliding support: The main idea is to control the levelness of the pre embedded steel plate sliding surface and the unconstrained sliding space. The elevation of the four corners of the pre embedded steel plate is controlled by a level. At the same time, sponge strips are used to make a frame around the surface of the pre embedded steel plate on the stair platform plate, which is tightly sealed. Qinghai polytetrafluoroethylene plate is used to prevent the concrete slurry from contaminating the sliding surface during the pouring of the upper concrete. The concrete of the upper stair section plate is poured again to isolate the platform plate from the upper stair section plate and meet the seismic requirements of the structure.
