Acrylic Filter Bags

Homopolymer acrylic filter bags are a specific type of filter bag made from homopolymer acrylic fibers. Due to their unique material properties, homopolymer acrylic filter bags offer significant advantages and unique performance in many industrial applications.

How Do Homopolymers Differ From Regular Polymers

The molecular weight distribution of traditional polymers is relatively wide, and the particles and structures also need to be controlled through a variety of technologies, making it difficult to achieve uniformity. Homopolymers, on the other hand, are polymer materials with high purity and consistency achieved by controlling factors such as the polymerization reaction temperature, ratio, monomer addition, type and amount of initiators, as well as highly precise control of parameters such as molecular weight and morphology.

Product Features

• Chemical Resistance

Homopolymer acrylic acid needle-punched filter bags have good corrosion resistance and are resistant to organic agents, oxidants, inorganic acids and organic acids and will not hydrolyze.

• Temperature Tolerance

Homopolymer acrylic filter bags can typically operate in temperatures up to 125°C (257°F), allowing for use in high-temperature applications.

• Durability

They have good abrasion resistance and mechanical strength, ensuring a longer lifespan compared to other types of filter materials.

• Low Energy Consumption

Homopolymer acrylic filter bags are soft in texture, require low cleaning pressure, have good vibration during cleaning, and are easy to remove dust, effectively reducing the consumption of compressed air, reducing maintenance, and saving operating costs.

Post-Treatment

For acrylic filter bags, we can treat it with different post-processing according to different working conditions. There are mainly the following post-processing treatments:

How Philite® Improve the Performance of Acrylic Filter Bags

• To increase system filtration capacity by 50-150% as needed without major changes to the dust collectors.
• System cleaning efficiency markedly increased with the effective increase of bag to bag distance.
• Bag life extended due to significant reduction of fatigue damage to the bags due to bag to cage impact.

Applicable Industries

Acrylic filter bags have good anti-chemical and anti-hydrolysis performances in filter bag family. It is widely used in the detergent, waste incinerators, asphalt, dance spray dryer, cement factories, coal mill and power plant for dust collection.

• Smoke filtration

Acrylic filter bags can filter out particulate matter in the smoke, purify the smoke and protect the environment. They are commonly used in smoke purification systems, combustion equipment and other fields.

• Liquid filtration

Acrylic filter bags can filter out impurities and solid particles in liquids, and are commonly used in water treatment, chemical and other industries. It can effectively remove suspended matter, impurities and microorganisms, making the liquid purer and cleaner.

• Dust filtration

Acrylic filter bags can also be used in industrial dust filtration, such as cement plants, metallurgical plants, etc. It can effectively capture dust and prevent it from entering the air and polluting the environment.

• Solid-liquid separation

Acrylic filter bags can be used to separate solid-liquid mixtures and separate solid particles from solutions. Common application scenarios include chemical, pharmaceutical and other industries.

We Pay Attention to Every Processing Detail:

• Accurately design the size of the filter cloth required for the filter bag. The filter cloth will be larger than the actual design size to leave enough operating space.
• Choose the right filter bag accessories and check their quality.
• We draw, cut and sew the filter bags on an automatic production line. When the filter bag needs to be processed manually, we open it on the operating platform and use a certain pulling force to keep it flat.
• We maintain strict processing quality standards in accordance with design drawings and operating procedures. Our workers dress in compliance with safe construction requirements and are prohibited from smoking.

Use and Maintenance

• In order to ensure its efficient operation and extend its service life, acrylic filter bags need to be maintained and cleaned regularly.
• Check the appearance of the filter bag regularly to see if there is any damage, wear or holes. If any damage is found in the filter bag, it should be replaced in time.
• The filter bag should be stored in a dry place to avoid mold growth, and avoid direct sunlight to prevent aging of the acrylic material.
