P84 polyimide felt

Types of p84 polyimide felt

P84 polyimide felt is a high-performance synthetic felt made from polyimide fibers. It is mainly used in the industrial filtration sector to create bag filters for dust collectors and other filtration systems. Due to their high-temperature resistance, P84 polyimide felts can withstand burning heat. This makes them excellent candidates for use in high-temperature filtration applications. Additionally, they possess excellent chemical stability, making them resistant to a wide range of chemicals.

P84 polyimide felt is available in various types and specifications, including P84 felt with a breathable membrane, P84 polyimide micro-denier felt, and P84 polyimide/profiled ribbed felt.

• P84 felt with a breathable membrane: The P84 membrane filter bag serves as a barrier to protect the filter felt from dust and particulate matter. This creates a filter cake on the outside of the bag, which acts as an additional filtration layer, increasing the bag's filtration efficiency. Furthermore, the filtering principle and the protected filter cake prolong the life of the filter bag. It can also provide improved bag cleans.
• P84 polyimide micro-denier felt: The typical micro-denier felt is composed of greater than 1.5 deniers fibers. They offer a larger surface area for filtration, meaning that even smaller particles can be captured. Another characteristic of micro-denier fibers is their yarn that makes up the felt. The tighter weave provides higher filtration and lower airflow.
• P84 polyimide/profiled ribbed felt: The profiled ribbed P84 polyimide felt is produced with ribs on the surface, providing a larger filtration area. The P84 ribbed felt makes an improved filter that extends the bag's life. Apart from that, it has lower residual pulses and higher filtration rates.

Specification and maintenance of p84 polyimide felt

Specifications

• Thickness

  P84 polyimide felt comes in various thicknesses, ranging from 1mm to 2mm. The choice of thickness influences the baghouse filter's dust release.

• Width

  The width of P84 felt filters can vary, but industrial-grade filter widths are usually 2m or 2.4m.

• Length

  The length of P84 polyimide filter bags can also be customized based on specific requirements in industrial filter applications.

• P84 fiber diameter

  The fibers that make up P84 polyimide felt have a diameter of around 8-10 micrometers. This smaller size contributes to a larger surface area and better filtration performance.

Maintenance

• Regular inspection

  Check for signs of wear, damage, or distortion to the filter felt, such as holes, cracks, or clogs.

• Dust removal

  Implement periodic cleaning to take off the dust and particulate matter that accumulates on the P84 polyimide felt surface. This can help to prevent clogging and maintain good airflow.

• Avoid chemical damage

  Be careful to avoid exposure to harsh chemicals or solvents that can cause damage to the felt filters. If cleaning agents are needed, choose mild ones and ensure proper dilution.

• Maintain proper humidity

  Control the humidity levels since excessive moisture can lead to the growth of mold or bacteria on P84 felt, while too low levels can make it brittle.

• Prevent static buildup

  Take measures to prevent static electricity buildup in the felt, which can attract dust and particles, making it harder to filter.

Scenarios of P84 polyimide felts

The P84 polyimide felt is considered a multifunctional textile that can be used in many industries for various applications.

• Heat insulation

  P84 polyimide insulation felt is mainly used in high-temperature applications. This is because P84 itself can withstand high temperatures. The felt can be used to make thermal insulation blankets that offer protection against heat, high temperatures, and fire.

• Filtration

  P84 polyimide microfiber felt has fibers that make very small gaps. This features helps to create a very fine filtration. Thus, it is widely used in air filtration and industrial liquid. In dust control cartridges and bag filters, P84 filtration felts can capture fine particles. The extraction systems let clean air pass through by leaving behind the pollutants in the filters.

• Cushioning and damping

  P84 polyimide felts are also available in high-impact damping applications. The felt has excellent damping behavior. Thus, it can absorb and reduce impacting energy. This makes it protective to delicate equipment and machines.

• Conveyor belts

  P84 polyimide conveyor belts are usually used in the manufacturing and processing industry. This is mainly because it can withstand extreme temperatures, unlike other materials. It is also chemical-resistant; thus, it does not get damaged easily. P84 polyimide conveys the durable strength and resilience that is needed in heavy industries.

• Electrical insulation

  The P84 polyimide has excellent dielectric strength. This also contributes to excellent electrical insulation. They can also be utilized in electrical insulation systems for electrical machinery like motors and transformers. They insulate electrical components by preventing electric currents from passing through different elements.

How to choose p84 polyimide felt

When selecting polyimide felt for a specific application, it's crucial to consider several key factors related to performance needs and requirements.

• Temperature Resistance

  Choosing the correct temperature resistance is very important. Buyers need to look at the upper limit of temperature resistance of the heat-resistant p84 polyimide felt. Make sure that its upper limit of temperature resistance matches the working environment's highest temperature.

• Thickness

  Thickness affects not only the felt's flexibility but also its insulation and durability. Choose the appropriate thickness according to the specific requirements of the application, which must ensure optimal performance and reliability.

• Density

  Density affects strength, insulation, and resistance to wear. In high-pressure situations, high-density felt should be selected to ensure the lifespan of equipment and maintain optimal performance. On the contrary, buyers can choose low-density felt when dealing with low-pressure situations.

• Width and length

  Width and length are also essential factors. Buyers need to make sure that the size of the polyimide felt matches the required dimensions to ensure proper coverage and fit.

• Felt Type

  Based on specific usage scenarios and needs, buyers can select different types of polyimide felt, such as compressing, insulating, or filtering felt, to ensure optimal functional performance.

• Cost and Quality

  Polyimide felt is used in many fields. Buyers must consider the balance between cost and quality to ensure that they get products that meet performance requirements and budget constraints.

Q&A

Q: Does the P84 polyimide felt thermal insulation need to be maintained?

A: While polyimide felt is very durable, regular checks should be done to see if the insulation is still intact and functioning. Unlike other types, it does not need frequent cleaning.

Q: What is the temperature rating for P84 polyimide felt?

A: The temperature tolerance range for polyimide felt is between -267 and 260 degrees Celsius.

Q: Can P84 polyimide felt be recycled?

A: There is no information stating that it can or cannot be recycled. However, most manufacturers encourage suppliers to reuse the material rather than dispose of it.
