We deeply understand the importance of efficient dust collection equipment for environmental protection and production efficiency in industrial production, and are committed to providing you with the highest quality products.

Below is a detailed introduction to the material types of industrial bag dust collector filter bags. What are the different characteristics and applications of different materials?

I、 Common Material Characteristics and Applications

1. Polyester fiber (PE) filter bag

characteristic:

It has good acid and alkali resistance and can be used in weakly acidic and weakly alkaline environments.

Relatively low price, high cost-effectiveness.

High tensile strength and good wear resistance.

The working temperature is generally below 130 ℃.

Application: Commonly used for collecting general industrial dust at room temperature or low temperature, such as dust filtration in industries such as food processing, pharmaceuticals, electronics, etc.

2. Polypropylene (PP) filter bag

characteristic:

Good acid and alkali resistance, especially to inorganic acids and bases.

Low density and light weight.

Has good resistance to hydrolysis.

The working temperature is generally around 90 ℃.

Application: Suitable for filtering dust with low temperature and relatively weak corrosiveness in industries such as chemical and sewage treatment.

3. Fiberglass filter bag

characteristic:

Excellent high temperature resistance and can be used for a long time at around 260 ℃.

High tensile strength and good dimensional stability.

Has good corrosion resistance to various chemical substances, especially strong acids and bases.

Application: Mainly used for high-temperature flue gas filtration, such as high-temperature furnace exhaust treatment in industries such as steel, cement, and power.           

4. PPS (polyphenylene sulfide) filter bag

characteristic:

It has extremely high chemical corrosion resistance and strong resistance to acids, alkalis, oxidants, etc.

Good high temperature resistance, with a long-term use temperature of up to 160 ℃ and an instantaneous use temperature of up to 190 ℃.

Good flame retardancy.

Application: Widely used in industries such as power, steel, and waste incineration to treat dust containing corrosive gases and high-temperature flue gas.

5. PTFE (polytetrafluoroethylene) filter bag

characteristic:

The chemical stability is extremely strong and can almost resist the erosion of all chemical substances.

Excellent high temperature resistance, can be used continuously for a long time below 260 ℃, and the instantaneous temperature can reach 280 ℃.

Smooth surface, non sticky, and easy to remove dust.

Application: Suitable for harsh working conditions with high corrosiveness and high temperature, such as high-precision filtration and strong corrosive gas filtration in industries such as chemical, pharmaceutical, and electronics.

II. Considerations for choosing filter bag materials

1. Working temperature

Choose the appropriate filter bag material based on the temperature of the flue gas or dust processed by the dust collector. If the temperature is too high, choose filter bags made of high-temperature resistant materials such as fiberglass, PPS, PTFE, etc; If the temperature is low, materials such as polyester fiber and polypropylene can be chosen.

2. Chemical corrosiveness

Analyze the chemical substances contained in the dust or flue gas to be processed and determine its corrosiveness. For highly corrosive working conditions, materials with strong corrosion resistance, such as PTFE, PPS, etc., should be selected.

3. Dust characteristics

Consider the particle size, shape, hardness, and other characteristics of dust. If the dust particles are fine or sticky, it is necessary to choose filter bag materials with smooth surfaces and high filtration accuracy to prevent dust from clogging the filter bag.

4. Service life and cost

The service life and price of filter bags made of different materials vary greatly. When choosing filter bag materials, it is necessary to comprehensively consider the factors of service life and cost, and choose materials with high cost-effectiveness.

In short, selecting the appropriate filter bag material requires comprehensive consideration based on specific working conditions and requirements to ensure the efficient operation and long-term stability of the dust collector.
