How to slow down the aging of polytetrafluoroethylene sheet

2023-02-09

Polytetrafluoroethylene plate has no toxicity, smooth surface, neat, corrosion resistance, excellent electrical insulation performance, low temperature performance and other advantages. Widely used in chemical, electric power and other industries. Ptfe sheet can also be used as engineering plastics in machinery, chemical and other facilities. In these places, the use of polytetrafluoroethylene plate low temperature toughness, corrosion resistance and lubrication.


Teflon sheet


In the mining industry, PTFE sheet is used as the sliding surface of chute and silo, using its excellent wear and chemical resistance. The new generation of self-unloading ore carriers, railway wagons and lorries may use teflon sheets because of their smooth surface, non-adhesion and anti-wear properties. These characteristics make it can also be used in agriculture and earth-moving machinery, with PTFE sheet material to protect steel.


Food processing solutions with polytetrafluoroethylene plate for contact surface and roller, with self-lubricating, water resistance and chemical cleaning resistance. In order to increase the service life and smooth operation, synchronous screw feeder and tooth belt made of polytetrafluoroethylene plate are often used in the filling production line. Teflon sheets are used in bearings, desiccated plates, rails and filtration systems in the paper and wastewater treatment industries. Ptfe plate used as electrolysis cell baffle, showing good corrosion resistance of the material.


Teflon sheet is a recently developed material currently under development. Such fibres are already used in racing sailing boats, where the material is required to be mould-resistant and the parts to be made of a stable size and light weight. Such fibers are also used as reinforcing materials for composite structures.


A lot of things have aging problems, teflon board also has aging problems. Ptfe sheet in the atmosphere, sunlight and oxygen under the action of aging, discoloration, cracking, brittle or powder, loss of its mechanical properties. In the forming processing conditions, also due to chemical action, so that the viscosity of the solution is reduced, discoloration, pattern, so in the forming processing and application process or material selection should pay attention to.


Polytetrafluoroethylene sheet material is a new technology product that Chinese enterprise develops independently on the premise of referring to overseas advanced technology. State Economic Commission included in the national technology innovation project. The plate has light weight, impact resistance, anti-wear, corrosion resistance, small friction resistance, energy absorption, aging resistance, flame retardant, static resistance and other excellent characteristics, the application of PTFE plate lined power plant, coal mine coal bunker; Ore and other material silos of chemical plants, smelters and aluminium plants; Food, feed, pharmaceutical industry of food, port silo, etc., can prevent sticky material, accelerate the opening rate, avoid blocking accidents, save the input and cost of air cannon. Lining the bulk bunker prevents powder from sticking to the bunker and mitigates damage to the wall by handling machinery.
