摘要:
A seam-sealed filter in which the seam is sealed with a seam tape comprised of an expanded fluoropolynier, such as ePTFE and copolymers thereof, having a crosswise matrix modulus of greater than 1,950 psi and an enthalpy ratio of less than 0.6 is disclosed. Such seam-sealed filters are capable of undergoing greater than 50,000 pulse- jet or reverse air cleaning cycles without substantial cracking or peeling of the sealed seam. Accordingly, the seam-sealed filters in the form of bags are particularly suitable for use in reducing particulate emissions in cement baghouses and the like.

公开了一种接缝密封的过滤器,其中接缝被包括膨胀的氟聚合物(例如ePTFE及其共聚物)的接缝带密封,其具有大于1,950psi的交叉矩阵模量和小于0.6的焓比。 这种接缝密封的过滤器能够经受大于50,000次脉冲喷射或反向空气清洁循环,而不会明显地破裂或剥离密封接缝。 因此,袋形式的接缝密封过滤器特别适用于减少水泥袋屋等中的微粒排放。
