Flue gas desulphurisation filter cloth is a crucial component of the flue gas desulphurisation system, and its quality and performance are directly linked to the efficiency of desulphurisation processes and their environmental protection outcomes. This article aims to provide an overview of the production process for flue gas desulphurisation filter cloth, encompassing raw material selection, manufacturing process, and quality control. A comprehensive analysis of the production details will be presented.
Raw material selection
The primary raw materials used in the manufacture of flue gas desulphurisation filter cloth include polyester and other high-strength, wear-resistant synthetic fibers. These materials are chosen based on their superior physical and chemical properties to satisfy the diverse requirements inherent in the desulphurisation process.
Manufacturing Process
The manufacturing process of FGD filter fabrics involves a number of key steps, each of which has a direct impact on the quality and performance of the final product.
Twisting: According to the requirements of the warp and weft yarns of the filter cloth, some yarns need to have a certain degree of twist in order to improve the strength of the yarns.
Warping: A certain number of warp yarns are arranged evenly and neatly on the warp beam under a certain tension according to the specified length and width.
Drawing-in: The warp yarns are sequentially threaded through the heddles, forming odd and even groups that pass through two separate heddles.
Weaving: in the loom, the warp and weft yarns in accordance with the predetermined rules interwoven into fabric. During the weaving process, the warp yarns should maintain a uniform and appropriate tension to ensure that the weft yarns can be smoothly interwoven to form a certain organisation, amplitude and density of the filter fabric.
Heat Setting and Calendering: Heat setting and calendering enhance the thermal stability of the filter cloth, alter its air permeability, and improve its filtration capability.
Cutting: According to the width required by the order, cut the filter cloth and seal the edge to prevent the edge from peeling off in the process of using and improve the working efficiency.
Clipper Seam: According to the requirements of the production order, the filter cloth is subjected with clipper seam install to achieve the connecting.
Gluing: The main purpose of glue treatment is to protect the clipper seam, preventing damage during use.
Bolian Filter Cloth strictly adheres to the manufacturing process, with each step meticulously controlled. Every piece of filter cloth complies with ISO9001 standards, ensuring consistent quality and performance.
