Among all organic fluoropolymers, polytetrafluoroethylene (PTFE) has the best anti-corrosion performance and is the most widely used, so it is called 'the king of plastics'. aspect. There are many anti-corrosion methods for metals. Polytetrafluoroethylene (PTFE) resin was invented by Dr. It has simple construction, convenient maintenance, low cost and wide adaptability. It can resist almost all chemicals except for molten alkali metal lithium, sodium, potassium, chlorine trifluoride, oxygen trifluoride at high temperature, and high flow rate liquid fluorine. Among them, organic coating anti-corrosion is one of the most common and important methods.
Plankett in 1938, and officially put into industrial production by Du Pont in 1950. However, due to some inherent defects of PTFE, especially its large cold flow performance and poor processing performance, its application is subject to certain restrictions. The phenomenon of metal corrosion is common and brings huge losses to the national economy. With the development of social economy, the improvement of people's living standards and the enhancement of awareness of environmental protection, higher requirements are put forward for coatings and coating methods.
Therefore, in-depth study of the properties of PTFE, improvement of its processing performance, and development of new PTFE composite materials have become the main research and development direction PTFE fiberglass adhesive tape of PTFE.At present, metals and their alloys are still very important structural materials, and their applications are in various fields of the national economy.
Organic fluoropolymers have excellent chemical resistance, heat resistance, weather resistance, non-stick performance and lubricating properties, etc. It can work at ~180\u0026mdash;260°C for a long time, and has excellent electrical insulation, anti-sticking properties, and low friction coefficient. Media (including concentrated nitric acid and aqua regia) erosion. PTFE has very good corrosion resistance and heat resistance., which have attracted more and more attention and are widely used in heavy anti-corrosion, high-end decoration, anti-sticking and lubrication treatments, etc
