Price per square meter of polytetrafluoroethylene board

In order to meet the design concept of free sliding of the sliding support at the support end of the stair section under earthquake action, if the decoration method of the rest platform is still constructed according to ordinary stairs, the PTFE board stair damping plate of Xingyu Company will inevitably cause local damage to the decoration materials under earthquake action. Therefore, when designing decoration drawings, it is necessary to consider the method of horizontal joints. When deepening the design and layout of decoration, it is possible to consider breaking the decoration materials at the horizontal joints and filling them with flexible materials. In the new design standards and drawings, the role of staircase design in the seismic design of the entire structure has been gradually enhanced, as stated in the "Code for Seismic Design of Buildings"

There are two types: molding and turning. The molding plate is made of polytetrafluoroethylene resin molded by molding at room temperature, and then sintered and cooled to produce. Turning plate is a blank made of polytetrafluoroethylene resin by compression molding, sintered, and then turned into a finished product. 1. Application: Polytetrafluoroethylene plate is suitable for use as a gasket, sealing component, and lubricating material in various corrosive media at temperatures of ℃. It is also used as an electrical insulation component for various frequencies. 2. Appearance: (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.

Polytetrafluoroethylene (F4, PTFE) has a series of excellent performance characteristics: high temperature resistance - * operating temperature of 200-260 degrees, low temperature resistance - still soft at -100 degrees; Corrosion resistance - able to withstand aqua regia and all organic solvents; Climate resistance - better aging life in plastics.

Material performance
*The use temperature ranges from -200 to 260 degrees Celsius. Some materials are resistant to chemical corrosion and are resistant to all chemicals. The friction coefficient is very low in plastics. Polytetrafluoroethylene is weather resistant and has good electrical properties. Its electrical insulation is not affected by temperature and is known as the "plastic king".

2. It is in a transparent or semi transparent state, and the higher the crystallinity, the worse the transparency. The raw materials are mostly powdered resins or concentrated dispersions, with a molecular weight of * and high crystallinity thermoplastic polymers.

3. Suitable for making corrosion-resistant parts, wear-resistant parts, sealing parts, insulation parts, and medical device parts (1 K) 4

Molding performance
1. Crystalline material with low moisture absorption.

2. Poor fluidity and easy decomposition, producing corrosive gases during decomposition. It is advisable to strictly control the molding temperature, heat the mold, and reduce the flow resistance of the pouring system for PTFE pipes.

3. Powdered resins are often formed using powder metallurgy and sintered methods. The sintering temperature should be 360-375 degrees, and should not exceed 410 degrees. Lotion resin is usually processed by cold extrusion and then sintering, which can form an anti-corrosion coating on the surface of articles. If transparency and good toughness are required for the product, rapid cooling should be adopted. Extrusion molding can also be used, which can extrude pipes, rods, and profiles.

4. The viscosity of PTFE melt is very high, and the viscosity of the container decreases with the increase of shear stress, indicating its non Newtonian fluid characteristics. Secondary processing can include hot pressing composite, welding, bonding, reinforcement, mechanical processing, etc., to produce the final product.

Quality standard for sliding bearings of polytetrafluoroethylene board stairs
(1) The variety and specifications of polytetrafluoroethylene plates must comply with the design requirements and construction specifications.
(2) The installation of polytetrafluoroethylene plates must be firm and free from bending or tilting.
(3) The surface of polytetrafluoroethylene board should be flat, clean, free of stains, and undamaged.
(4) The allowable deviation should comply with the regulatory requirements.
Price per square meter of polytetrafluoroethylene board Why is it necessary to use 5mm PTFE stair treads on building stairs?
The answer is determinable!!
1. We attach great importance to the safety of residents' homes
2. The frequent occurrence of natural disasters leads to the damage of stairs, making it impossible to escape and rescue.
3. Polyethylene tetrafluoroethylene board has low lubricity and plays a buffering role in earthquake resistance. The purpose of designing sliding supports to construct stairs is that in the event of an earthquake, the sliding stairs can vibrate as an independent unit with a 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 their stairs and ensuring that the passage is not first damaged and unobstructed, allowing personnel to evacuate in a timely manner. The thickness of the PTFE board for stairs is 5mm, with a length equal to the length of the stair board and a width equal to the width of the stair tread. Cutting the PTFE board on the stairs requires the use of a profile cutting machine. After the installation of the PTFE board on the staircase is completed, cover the easily contaminated areas with adhesive paper or cover them with plastic film for protection. Protect easily scratched areas with safety barriers.
