The filter material of the easy-cleaning needle felt is made of non-woven acupuncture and is made by heat setting and other processing methods. Easy to clean gray needle felt filter material permeability is good, after heat treatment, the surface is smooth, not easy to deformation, easy to remove dust. If the filter material of the easy-cleaning needle felt is subjected to corresponding water and oil-repellent treatment, it can be well applied to the high moisture content or the dust condition containing a small amount of oil, not only preventing the paste pocket, but also prolonging its use. life.
The easy-to-clean acupuncture felt dust filter bag is generally easy to remove dust on the surface of the needle felt filter material, and can be widely used in industrial dust collection, dust control and so on. The filter materials that can be easily cleaned can be polyester, polypropylene, acrylic, etc. Under the condition of normal temperature, most of us use polyester easy-purple needle felt filter bag.
The smoothness of the surface of the filter material has a great influence on the dynamic running resistance of the filter material. The initial resistance of the filter material depends on the air permeability of the filter material, and the resistance during operation is many times larger than the initial resistance. The running resistance depends on the smoothness of the surface of the filter material, the cleaning effect, etc. Generally, it is hoped that the filter material ensures that when the same filtration efficiency is reached, the greater the air permeability, the better the resistance as low as possible because it can save a lot of energy and use the air flow reversed. In the dust-removing dust remover, when using the same pressure and the air flow of the same air volume is used for cleaning, the cleaning effect when selecting the weaving material having a large air permeability for the filter bag is better than that of the fabric with a small air permeability.
Therefore, under the condition that the filter material can achieve high filtration accuracy, how to improve the air permeability of the filter material and improve the degree of surface smoothness, reduce the dust adhesion, and reduce the running resistance are the topics that the filter material production plant should study first. Okay environmental protection production of easy clean needle felt filter material, its permeability is higher than the ordinary calender finishing filter material, and the smoothness of the surface is also higher than the ordinary dust filter. Therefore, the surface of the needle-punching filter felt, which is easy to be cleaned, has a smooth surface, good air permeability and low resistance, and thus becomes a very good filter material in industrial dust removal.
