Akrilik Filtre Torbaları

Acrylic filter bags are a type of filter bag made from acrylic fibers, which is a synthetic fiber that is known for its durability, chemical resistance, and heat resistance. As a dust filtration media, acrylic felt has the following characteristics:

  • Particle Retention – Acrylic filter bags are highly efficient in retaining particles, thanks to their intricate pore structure. These bags can capture particulate matter of various sizes, ranging from coarse to fine particles.
  • Kimyasal Direnç – Acrylic fibers possess excellent resistance to a wide range of chemicals, making them suitable for filtration applications where aggressive chemicals are being filtered.
  • Sıcaklık Dayanımı – Acrylic filter bags exhibit good thermal stability, allowing them to withstand elevated operating temperatures. They can typically operate in the temperature range of 120°C to 150°C (250°F to 300°F), making them suitable for filtration processes that involve hot gases or liquids.
  • Hydrolysis & Moist Heat Resistance – Acrylic fibers have low water absorption properties, enabling the filter bags to maintain their filtration efficiency even in high-humidity environments with mild chemical attacks. Where polyester filter bag is not suitable because of potential hydrolysis, acrylic filter bag offers a combination of abrasion and moist heat resistance, particularly under acid conditions.

In addition to these filtration characteristics, acrylic filter bags also offer a number of other advantages, such as:

  • Cost-Effective – Acrylic fabric is relatively inexpensive compared to other high-performance filter media materials, making it a cost-effective solution for a wide range of industrial filtration applications.
  • Versatility – Acrylic filter bags can be customized to meet specific filtration requirements, including shape, size, and surface finishes. Additionally, they can be designed to fit different types of dust collectors, allowing for easy installation and replacement.
  • Long Service Life – Acrylic fibers are known for their durability and resistance to degradation, resulting in extended service life. This reduces the need for frequent replacement, saving maintenance costs in the long run.
  • Resistance to Abrasion – Acrylic filter bags demonstrate excellent resistance to mechanical stress and abrasion, preserving their filtration efficiency over time, even in demanding industrial environments.

Scrim-supported felt is used exclusively in the production of our acrylic filter bags in order to improve filtration efficiency and extend the filter bag life.

Arcylic Filter Bag Construction & Treatment

Acrylic filter media can be constructed and treated with various options so that they become best suited for various operating conditions, applications, and industries.

Filtre Malzemesi Yapısı

Needle Felting

Needle felting is a traditional non-woven fabrication process by punching a fiber batt into itself to hook and entangle fibers which then form a thin, relatively dense structure, either with or without a light woven support scrim. Needlefelt filter media have smooth surfaces and offer good depth filtration and particle capture. To further improve filtration efficiency and filter bag life, Aokai custom designs and manufactures Dual-Density Acrylic Filter Media. In a genuine dual-density filter media, two layers of media of different density are separated by a scrim in the middle that provides dimensional stability and a densified central core which improves filtration efficiency by minimizing dust migration through the felt. The scrim structure offers a clear advantage over unsupported felts (without scrim) which are produced in a single process with a homogeneous fiber blend and filtration characteristics only.

Filtre Ortamı Arıtımı

Adding an ePTFE membrane to an acrylic filter bag allows the membrane to act as the filter cake. Dust stays on the surface of the membrane and does not get entrained into the fibers of the filter bag, which lengthens the filter bag life. It also reduces wear and tear, lower maintenance costs, and energy costs due to easy dust cake release during the cleaning cycle.

The filter media is coated in a bath or spray of liquid PTFE resin. This is done to protect filter bags. The treatment improves the flex life, heat and chemical resistance, and dust release from the filter bags. This increases the service life and filtration efficiency. PTFE finish is commonly used in applications with corrosive chemical compounds, sticky dust, or high moisture contents.

This coating adds resistance to water and oils, and improves cake release.

Helps to ground the filter bag to eliminate sparks that might cause combustion explosions.

Singeing, filtre medyasının yüzeyinin bir aleve veya sıcak gaza maruz bırakılarak ince ve dağınık elyafların yakıldığı bir sonlandırma işlemidir ve bu sayede daha düzgün ve pürüzsüz bir yüzey alanı elde edilir, bu da kek salınımını, gelişmiş filtrasyon verimliliğini ve daha iyi hava geçirgenliğini artırır.

Yakma işlemi tipik olarak kumaşın açık bir alevin üzerinden veya ısıtılmış bir odadan geçirilmesini içerir. Isı, kumaşın ana yapısına zarar vermeden çıkıntı yapan lifleri yakar. Hız ve sıcaklık gibi proses parametreleri, istenen pürüzsüzlük ve finisaj seviyesine ulaşmak için dikkatlice kontrol edilir.

Glazing, also known as calendering, is the high-pressure pressing of the fabric by rollers to flatten or smooth the surface. Glazing pushes the surface fibers down onto the body of the filter media to increase and uniform surface life, improve stability, reduce shrinkage, and improve dust cake release.
