Junzheng editor analyzes the characteristics of the surface easy to dust and dust bag
The surface easy-cleaning dust-removing and dust-removing bag is surface scorched and calendered on the basis of general polyester needle felt. The easy-cleaning dust-removing and dust-removing bag makes the surface lubricating, and the air permeability is good. Labor intensity of dust collector bag.
The surface is easy to clean and easy to clean. The general polyester needle-punched filter felt uses the process of first burning and then calendering in the post-treatment process to make the surface of the filter material smooth, the dust is easy to peel off, and the air permeability is slightly higher than that of ordinary felt. class. The surface is easy to clean, the surface of the dust bag is lubricated, the air permeability is good, and the labor intensity of the dust bag is reduced during use. The surface easy-cleaning dust-removing and dust-removing cloth bag is made of 1-2.5D polyester fine denier yarn, and the high-strength and low-stretch yarn is used to weave the reinforced base fabric, which is reinforced by needling and post-treatment. This product has the characteristics of high porosity, good air permeability, moderate acid resistance and alkalinity, and a very good abrasion resistance, so it is one of the most widely used felt filter materials. kind. The weight is from 350g / ㎡-800g / ㎡ and the thickness is from 1mm-4mm. Post-treatment methods include calendering, scorching, heat setting, dipping and drying, coating, etc. It has the characteristics of stable scale, easy dust removal and long service life.
The longitudinal stitches of the dust bag must be strong, straight and no less than three; the annular stitches at the mouth of the filter bag must be strong and no less than two; There should be no less than two on each side. The loop stitching at the bottom of the filter bag allows a single thread, but it is necessary to sew more than two turns. The tolerance of the length of the bag is ± 10mm, and the needles around the bag must be uniform. The stitch size should not be less than 250px for 15 stitches, and not less than 250px for 12 stitches in the transverse direction; the sewn bag must not have holes and damage defects; the bag with a diameter greater than 200mm and a length greater than 5000mm should be subjected to a tensile test, and its elongation should be Meet the requirements.
The degree of surface lubrication of the filter material has a great influence on the dynamic running resistance of the filter material. The initial resistance of the filter material is determined by the air permeability of the filter material, and the resistance in operation is many times greater than the initial resistance. The running resistance depends on the degree of lubrication of the surface of the filter material and the dust removal effect. It is generally hoped that when the filtering data ensures the same filtering efficiency, the larger the air permeability, the better, that is, the lower the resistance, the better, because this can save a lot of energy. In the dust collector that uses airflow to blow back the dust, when the airflow with the same pressure and the same air volume is used for dust removal, the cleaning effect of the knitted fabric with a large air permeability is better than that with a small air permeability. . Therefore, under the condition of ensuring that the filter material has a high filtering accuracy, how to improve the air permeability of the filter material and the degree of surface lubrication, reduce the adhesion of dust, and reduce the running resistance are the topics that the filter material manufacturer should first study. The surface resinized lubricating needled filter felt developed and developed by our factory has an air permeability more than 50% higher than that of the common calendered filter media, and the surface lubrication degree is smoother than that of the calendered filter.
The dust-removing cloth bag produced by our company has high dust-removing efficiency, and can capture fine dust with a particle size larger than 0.3 micron. The dust-removing efficiency of the dust-removing cloth bag can reach more than 99%. Using sensitivity, the air volume can be from hundreds of cubic meters per hour to hundreds of thousands of cubic meters per hour. It can be used as a small unit directly installed indoors, near the machine tool, or as a large dust removal room, that is, a "bag house". The dust-removing bag structure is relatively simple, the operation is more stable, the initial investment is less, and the maintenance is appropriate and convenient. The choice of filter materials is also very careful. Junzheng Environmental Protection is very careful. Only by selecting the right filter material can the bag's operating time be added, which greatly reduces the cost of replacing the bag. During the operation of the bag, the bag will be stretched and shrunk. We must choose the filter material with the elasticity and moderate softness of the dust bag to the size and speed of the action of the bag. During the operation of the dust collector, the dust-containing gas enters the cabinet through the air inlet, and the speed of the dust outlet also determines the abrasion resistance of the dust bag.
Junzheng environmental protection equipment mainly produces high-temperature dust-removing cloth bags. Its products are well explained for its dust-removing purpose and are mainly sold to the country and other regions. Relying on the service concept of perfection, sound mechanism, and continuous strengthening, in order to facilitate the broad demand collective, our company spares no effort to provide perfect after-sales service, which is why it has received unanimous praise and praise from customers.
Junzheng environmental protection equipment products are of the same type, excellent quality, moderate price, timely delivery, sensitive strategy and good service. In order to facilitate the broad demand collectively, when customers pay online, cash, and bank transfer, we will send the high-temperature dust bag to the customer within the negotiation time on both sides. If you do n’t understand, you can call to know at any time . Together, our company also provides after-sales service for one year after the dust bag products are sold.
