P84 high temperature needle felt P84 high temperature needle felt is obtained by needle punching of polyimide fiber, and its characteristics are notable due to its own fiber fineness.P84 high temperature resistant dust-removing cloth bag fiber is also known as polyimide, and its basic chemical composition is mainly composed of aromatic units. P84 filter media […]
The harm of high differential pressure of bag filter The high differential pressure of the bag has a great influence on the service life of the filter bag of the bag filter. Due to the increase of the differential pressure, the filtering effect of the bag filter is significantly reduced, and the dust content in […]
How to prevent the dust filter bag from falling off The flat bag deforms larger than the round bag when the dust filter bag is cleaned by pulse blowing, so when the bag retracts after blowing, it will collide with the dust removal frame more strongly, resulting in more dust leakage, and it will be […]
Comparison of bag filter and electrostatic precipitator Advantages of bag filter: High dust removal efficiency, up to 99.9%； Less ancillary equipment, less investment, and technical requirements not as high as electric precipitators； Capable of catching dust with high specific resistance, which is difficult to recover by electric dust removal； The bag filter has stable and […]
Liquid filter bag Introduction: The filtrate surface of the liquid filter bag is treated with special singeing, which not only effectively prevents the fibers from detaching from the contaminated filtrate, but also avoids the traditional roller pressing treatment that causes excessive clogging of the filter holes and shortens the life of the filter bag. All […]
The relationship between the dust holding capacity of the dust filter bag and the filtration efficiency The dust holding capacity of the dust filter bag is also called dust load, which refers to the amount of dust accumulated on the filter material per unit area when a given resistance value is reached. The dust holding […]
Water and oil repellent filter material Water and oil repellent mechanism: Water and oil repellency means that the filter material is not wetted by water or oil to a certain extent. In theory, whether liquid B can wet solid A is determined by the surface tension of the liquid and the critical surface tension of the solid. If […]
Woven filter material The filter material of the bag filter is mostly made of manufactured materials. Due to some characteristics and filtering conditions of woven fabrics, it has been applied in many ways. The woven filter material is made of twisted warp and weft yarns or monofilaments interwoven by a loom. Since the warp and […]
Characteristics of Aramid Good mechanical properties. Meta-aramid is a flexible polymer with higher breaking strength than ordinary polyester, cotton, nylon, etc. with higher elongation, soft hand feeling, good spinnability, and can be produced into different deniers and lengths. The short fibers and filaments are made into fabrics and non-woven fabrics with different yarn counts in […]
Wet spinning Introduction： Wet spinning is referred to as wet spinning. A chemical fiber spinning method in which polymer is dissolved in a solvent, and a thin stream is ejected through a spinneret, and then enters a coagulation bath to form fibers. The fiber-forming polymer suitable for wet spinning has a decomposition temperature lower than […]
