Detailed introduction of PTFE board

(1) The color of the board is the natural color of resin.

(2) The texture should be uniform, and the surface should be smooth, and no defects such as cracks, bubbles, delamination, mechanical damage, knife marks, etc. are allowed.

(3) A slight cloud-like elasticity is allowed.

(4) It is allowed to have 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 in an area of ​​10×10cm.

(5) The density is 2.1-2.3T/m3.

PTFE board features: excellent chemical stability, corrosion resistance, tightness, high lubrication, non-stick, non-toxic, electrical insulation and good anti-aging endurance.

Polyethylene tetrafluoroethylene plate (polyethylene tetrafluoroethylene plate) for construction of Sichuan Nanchong project (installation steps):

Application of low friction performance in terms of load. Because the friction part of some equipment is not suitable for lubrication, such as the occasions where lubricating grease will be dissolved by solvents and fail, or products in the industrial fields such as papermaking, pharmaceuticals, food, textiles, etc., it is necessary to avoid lubricating oil contamination , Which makes the filled PTFE material an ideal material for oil-free lubrication (direct load bearing) of mechanical equipment parts. This is because the friction coefficient of this material is lower among known solid materials. Its specific uses include bearings for chemical equipment, papermaking machinery, agricultural machinery, as piston rings, machine tool guides, guide rings; in civil engineering, it is widely used as bridges, tunnels, steel structure roof trusses, large chemical pipelines, and storage tanks. Support sliding block, and used as bridge support and bridge swivel, etc.

Polytetrafluoroethylene (PTFE) has excellent chemical stability, can withstand all strong acids, strong alkalis, and strong oxidants, and does not interact with various solvents. PTFE has a wide operating temperature range. It can be used for a long time at -180℃~250℃ under normal pressure. After 1000h of treatment at 250℃, its mechanical properties will change little. PTFE has a very low friction factor, is a good anti-friction, self-lubricating material, its static friction coefficient is less than the dynamic friction coefficient, so it has the advantages of low starting resistance and smooth running when used to make bearings. Because PTFE is non-polar, heat-resistant and does not absorb water, it is also an excellent electrical insulating material. It also has excellent aging resistance, non-stickiness and non-combustibility. The difference between Duoyao brand stair special PTFE board return material and new material: after the new material is processed into the product, the material around the glue port on the product can be added to the new material after being crushed. Second card: a material whose performance cannot meet the requirements in a certain aspect. Recycled materials: re-granulation after recycling. The nozzle mainly refers to the remaining part of the injection molded parts, which is broken, that is, the broken material, as if the leftover part of the food is eaten. Recycled materials refer to recycled and pelletized materials. It can be corner granulation or waste granulation, which refers to the materials that have been recycled and re-granulated by the machine. Recycling once is called recycled material, and recycling N times is also called recycled material.

How to fix the fluorine plate? What is fixed? Precautions for construction method! Stair PTFE board construction method M4 screws only serve to fix the polyethylene PTFE board, there is no difference between pre-embedded or post-installed, mainly depending on which method is more convenient for on-site construction. Usually, the M4 screw holes on the polyethylene PTFE board can be easily drilled with an ordinary electric drill.
