摘要:

为考察工业对聚四氟乙烯(PTFE)滤材的需求量,综述了PTFE耐腐蚀滤料在工业烟尘净化领域的应用特性、滤料的结构及组分特征以及其在工业除尘领域的发展趋势,重点分析了“十三五”期间其在垃圾焚烧、煤电、钢铁和水泥行业除尘领域的发展趋势。同时,根据PTFE滤料的组成结构,分析了PTFE膜裂纤维、基布、缝纫线和微孔膜在未来 5a 的需求规模。结果表明:至2020年末,垃圾焚烧、煤电、钢铁和水泥行业的烟尘过滤系统对PTFE滤料的累计需求量分别为880、180855.5、5 660和7  905 t,年复合增长率均超过10%;PTFE 滤料在“十三五”期间需求量的分析可为我国工业烟尘净化材料产业的发展提供参考依据。

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.
