The dust bag is usually selected according to the dust containing gas, the nature of the dust and the dust collection method of the dust collector. The following principles should be followed when selecting dust bag:

(1) The structure is reasonable and the capture rate is high;

(2) It is not easy to remove dust;

(3) Good air permeability, low resistance and high filtration precision;

(4) It has enough strength and good dimensional stability;

(5) It has good temperature resistance, chemical corrosion resistance, oxidation resistance, hydrolysis resistance and wide adaptability;

(6) The raw material source is wide, the performance is stable and reliable;

(7) Low price and long service life.

So what's the difference in the material of dust bag? Let's take a look at Fushun Bihai industrial cloth Co., Ltd. The material of dust bag is actually cloth or felt woven from synthetic fiber, fiber or glass fiber. At present, many customers want to sew cloth bags or felt into cylindrical, flat or shaped filter bags. Then, according to the nature of the flue gas, the suitable filter materials are selected.

How many kinds of commonly used dust bags are classified? Generally, they are divided into three types according to the temperature of working environment: normal temperature cloth bag, medium temperature cloth bag and high temperature cloth bag.

Normal temperature bag: including polyester needle dust collection bag, anti-static dust collection bag, waterproof and oil-proof dust collection bag, three prevention dust collection bag, supporting dust collection bag, used for general working environment such as wooden barrel, building materials, cement, etc. Medium temperature filter material: suitable for working conditions from 130 ℃ to 150 ℃, instantaneous temperature up to 180 ℃. The specific products include medium temperature polyester needle felt dust collection bag, medium temperature acrylic dust collection bag and medium temperature easy cleaning dust collection bag. Warm tips: the fabric and design of dust bag should be filtered, not easy to fall off, durable. Choosing a good dust collection bag will directly affect the dust removal effect of the dust collector. Our customers should consider several factors: gas temperature, humidity and chemical properties, particle size, dust concentration, filter wind speed, dust cleaning method, etc.
