Abstract:

In order to study the market industrial demand for polytetrafluoroethylene (PTFE) filter material, the main aspects (application in the field of filtration of industrial dust, structure and component of filters, and development in the purifying industry dust field) of polytetrafluoroethylene anti-corrosion filtration materials are reviewed. More importantly, the development of PTFE filters applied in the four main industrial fields (namely, waste incineration, coal-fired power plants, steel and cement) in the time period between 2016 and 2020 is analyzed. Additionally, on the basis of the structural characteristics of anti-corrosion filters, demands of PTFE split-film fiber, bearing cloth, sewing and micro-pore membrane are also predicted reasonably. The analysis indicates that the cumulative demands of PTFE filter materials of the purification system in the four main industrial fields will be 880, 18 855.5, 5 660 and 7 905 tons, respectively, implying that the increase ratio is over 10%. Analysis of demands of PTFE filter materials in next five years could provide the industry-purification system with a significant reference.
