Technical specifications of polytetrafluoroethylene board for staircase construction

Technical specifications of polytetrafluoroethylene board for staircase constructionTransporting highly corrosive gases and liquids at high temperatures is something that cannot be replaced by other pipelines. The difference between [Huawang] PTFE plate return material and new material is that after the new material is processed into a product, the material around the rubber mouth on the product can be crushed and added to the new material for use together. Side card: A material whose performance does not meet the requirements in a certain aspect. Recycled material: After recycling, the granulation water outlet mainly refers to the remaining part of the injection molded parts, which is crushed, like the leftover part from eating. Return material refers to the recycling of granulated materials. It can be corner granulation or waste granulation, referring to materials that have been recycled and re pelletized by machines. Recycling once is called recycling, and recycling N times is also called recycling. Fu Pai refers to plastic that does not meet inspection standards at the time of leaving the factory, and may not meet certain indicators compared to genuine plastic. However, it can still be used.【 Huawang 】 Polyethylene tetrafluoroethylene plate is used for low friction performance in terms of load. Due to the friction part of the equipment, it is not suitable to lubricate it with oil. For example, in situations where lubricating grease will be dissolved by solvents and fail, or in industrial fields such as papermaking, pharmaceuticals, food, textiles, etc., it is necessary to avoid lubricating oil contamination. This makes PTFE filling material the * * * material for oil-free lubrication of mechanical equipment parts (directly bearing loads). This is because the friction coefficient of the material is known to be lower among solid materials. Its specific uses include bearings for chemical equipment, papermaking machinery, and agricultural machinery, as piston rings, machine tool guides, and guide rings; Widely used in civil and architectural engineering as support blocks for bridges, tunnels, steel structure roofs, large chemical pipelines, storage tanks, as well as bridge bearings and bridge rotors. Introduction to polytetrafluoroethylene (PTFE) molded sheet: PTFE has excellent chemical stability and can withstand all strong acids, alkalis, and oxidants. It does not react with various solvents. PTFE has a wide temperature range and can be used at -180 ℃~250 ℃ under normal pressure. After being treated at a high temperature of 250 ℃ for 1000 hours, its mechanical properties change very little. PTFE has a very low friction coefficient and is a good anti friction, self-lubricating material. Its static friction coefficient is lower than the dynamic friction coefficient, so it has the advantages of low starting resistance and smooth operation when used to make bearings. Due to its polarity, heat resistance, and non water absorption, PTFE is also an excellent electrical insulation material. It also has excellent aging resistance, non stickiness, and non flammability.Example description: At 03:47 on August 8, 2017, the report of Jiuzhaigou Valley Scenic and Historic Interest Area County Emergency Office was received. Up to now, the M7.0 earthquake in Zhangzha Town, Jiuzhaigou Valley Scenic and Historic Interest Area County has caused 9 deaths (including 6 tourists, 2 locals, and 1 unidentified), 135 injuries (including 32 serious injuries and 103 minor injuries) (reproduced above). Huawang Company and all its employees pray for Sichuan. Hebei Huawang Sealing Materials Co., Ltd. suggests that in large buildings with high population density (such as shopping malls, schools, nursing homes, etc.), it is recommended to use 5mm polytetrafluoroethylene sliding supports for the stairs produced by Huawang Company, which is beneficial to ensure that the escape route is not first damaged in the event of an earthquake and to facilitate personnel evacuation. Product details: PTFE stair board is mainly used in engineering stairs as a hard PTFE stair support, which is widely used in current stair applications. Because the stairwell does not participate in the overall seismic calculation of the structure, sliding supports need to be designed according to traffic restrictions. Polytetrafluoroethylene board is currently known to have the smallest friction coefficient among solids (even smaller than ice). At the same time, the pressure required for the production of polytetrafluoroethylene board is greater than 30MPa, and the tensile strength of the product itself is greater than 15MPa (equivalent to the strength of C15 concrete in construction). The tensile ratio is greater than 150%. Choosing it in this area is based on two points: excellent sliding performance5.

1. The PTFE sliding plate used for stairs has the vertical stiffness and elastic deformation of ordinary plates, and can withstand vertical loads and adapt to rotation. By utilizing the low friction coefficient (μ f ≤ 0.08) between the PTFE plate and the stainless steel plate, the horizontal displacement of the upper structure of the building can be unrestricted

Made from PTFE molded blanks, it has excellent dielectric properties, anti-aging, chemical corrosion resistance, and a wide range of application strength and scale. The film is an non oriented film, which is limited to oriented and semi oriented films.
Application Scope of Polytetrafluoroethylene Plate
In terms of chemical engineering, it can be used as an anti-corrosion material and can be used to produce various anti-corrosion components, such as pipes, valves, pumps, and pipe fittings. In terms of chemical equipment, it can produce fabrics and coatings for reactors, distillation towers, and anti-corrosion equipment.
In terms of mechanical applications, polytetrafluoroethylene plates can be used as self-lubricating bearings, piston rings, oil seals, and sealing rings. Self lubrication can reduce mechanical wear and heat generation, and lower power consumption. Polyethylene PTFE board stair treads for electronic appliances: primarily used for making various wires and cables, battery electrodes, battery separators, printed circuit boards, etc.

The principle of the seismic resistant structure staircase made of polytetrafluoroethylene board is the active connection of nodes. When seismic waves come, the staircase and floor can move, thus avoiding the impact of building swing force on the staircase causing it to break and affecting personnel evacuation. Polytetrafluoroethylene is a solid material with the lowest known friction coefficient. Using the characteristic of low friction resistance to make bridge sliders and seismic staircase node pads is beneficial for their movement, avoiding thermal expansion and contraction and seismic wave impact damage to the structure.
