    Product Detail

    Description

    The melt filter element is installed in the extrusion line, where the polymer melt is forced through the filter to remove impurities. The filtered polymer melt then proceeds to the spinning process, where it is solidified into continuous filaments or staple fibers.

    Regular maintenance and replacement of the melt filter element are important to ensure the continuous and efficient operation of the chemical fiber production process. This helps to avoid production downtime, improve product quality, and ensure the longevity of the filtering equipment.

    Frequently Asked Questions
    ❓ What is a polymer candle filter element and where is it used?
    A polymer candle filter element is a filtration component installed in extrusion lines. It filters impurities from polymer melts before the spinning process, ensuring the production of high-quality continuous filaments or staple fibers in chemical fiber manufacturing.
    ❓ What materials are used to manufacture the melt filter element?
    The filter element is made from SUS304 or SUS316L stainless steel. The filter media consists of metal sintering mesh or stainless steel wire mesh, offering excellent corrosion resistance and durability under high-temperature and high-pressure conditions.
    ❓ What is the working temperature and pressure range of the candle filter?
    The polymer candle filter can operate within a wide temperature range of -60℃ to 500℃ (working temperature ≤350℃ for standard models). The maximum allowable pressure difference is 10MPa (10 bar / 14 psi), making it suitable for demanding industrial applications.
    ❓ Can the melt filter element be cleaned and reused?
    Yes. The polymer candle filter element features excellent structural strength and durability, allowing it to be cleaned and reused multiple times. This significantly reduces operating costs and minimizes production downtime during maintenance cycles.
    ❓ What filtration ratings are available for the candle filter element?
    The melt filter element is available in filtration ratings ranging from 1 to 200 microns. This wide range allows it to be customized for different polymer melt filtration requirements and levels of impurity removal precision.
    ❓ Can custom sizes and connector types be provided for specific filtration machines?
    Yes. We offer polymer pleated candle filters in various standard sizes (e.g., Φ35mm, Φ50mm in lengths from 425mm to 575mm) and support multiple connector types including 222, 226, 215, M36, M28, M24, M22, and M20. Custom specifications can be produced to meet your specific filtration machine requirements.
