PTFE was called "Plastic King", the father of fluororesin Roy Prycote 1936 DuPont in the United States began to study the replacement of freon, they collected some of the tetrafluoroethylene stored in the cylinder, ready for the second Day for the next experiment, but when the next day to open the cylinder after the valve, but no gas spill, they thought it was leak, but the cylinder weighing, found that the cylinder did not lose weight. They saw the cylinder and found a lot of white powder, which was PTFE.
The study found that Teflon has excellent properties and can be used for anti-fissure gaskets such as atomic bombs and shells, so the US military has kept the technology secret during World War II. Until the end of World War II before deciphering, and in 1946 to achieve industrial production of PTFE. PTFE is an important category of plastics. Since the synthesis of PTFE, the development and application of fluorine plastic has been greatly developed. Has been widely used in aviation, aerospace, electronics, electrical, chemical, chemical, construction, textile, pharmaceutical and other industrial sectors, and increasingly deep into the people's daily life.
In particular, PTFE materials in the anti-corrosion aspects of industrial applications, greatly promoted the development of chemical industry. PTFE heat exchanger has excellent heat transfer performance, good corrosion resistance, good stain resistance, small size, light weight, developed by the Zhengzhou University of Technology, PTFE fully play its anti-corrosion, chemical reagents, Wear resistance, toughness and high strength.
With the scientific and technological progress, the traditional anti-corrosion non-metallic materials, anti-corrosion equipment developed increasingly perfect, new corrosion-resistant non-metallic materials products continue to emerge. In the use of new technologies, new materials to develop anti-corrosion new products in the tide, Teflon anti-corrosion products thriving, rapid development.
PTFE sheet has a high degree of chemical stability, he can almost all of the commonly used strong corrosion, hydrogen oxidation of chemical substances, but also has the characteristics of high temperature, so it is an ideal anti-corrosion materials.
