Liquid filter bags are a type of filtration media used in various industrial applications to separate solid particles and contaminants from liquid substances. These filter bags are designed to capture and retain particles, impurities, and debris suspended in liquids, resulting in cleaner and clarified liquid output. Here's an introduction to liquid filter bags:

Construction: Liquid filter bags are typically made from a variety of materials, including felt, woven fabrics, or mesh. The choice of material depends on the specific application, the type of contaminants being filtered, and the required filtration efficiency.

    Product Description

    The Polypropylene (PP) filter bag is manufactured using polypropylene non-woven fabric. The fabrication of a Polypropylene filter involves fiber needling, which can be categorized into short fiber, filament, and mono-filament varieties. Different process requirements yield filter cloth with varying levels of precision. The unique internal honeycomb structure of this filter efficiently captures particulate matter and suspended impurities within liquid solutions. It stands out as the optimal choice for applications with high acid value requirements.

    Product Information

    The PP filter bag is meticulously produced through the needling process, creating a loose fiber structure that increases the capacity to hold impurities. This filter bag operates on a compound interception mechanism. Its internal honeycomb structure effectively separates solid and soft particles; larger impurities are captured on the surface of the filter fibers, while finer particles are trapped within the deeper layers of the filter material. This design ensures the filter bag remains intact even under increased pressure, maintaining high filtration efficiency.
    Furthermore, the external surface of the product undergoes a high-temperature surface heat treatment utilizing instant singeing technology, followed by calendaring treatment. This treatment effectively prevents the dislodging of fibers due to the high-speed impact of liquid during filtration. It ensures that no fibers are released, thus mitigating the problem of excessive filter hole blockage that can occur with traditional rolling treatment, ultimately prolonging the filter bags' lifespan. Importantly, this design maintains a low pressure differential, ensuring it does not impede the flow rate.

    Micron Ratings

    The micron rating of a liquid filter bag specifies the size of particles it can effectively capture. For instance, a 100-micron bag can capture particles with a size of 100 micrometers or larger. 

    The available relative filtration accuracies, expressed in micrometers (μm), are as follows: 0.1 μm

    0.2 μm, 0.5 μm1 μm3 μm5 μm10 μm25 μm50 μm80 μm100 μm200 μm300 μm600 μm. 

    These filtration accuracies cater to a wide range of filtration needs, allowing for precise customization based on the specific requirements of different applications.
