Polymer Candle Filter for High Viscosity Substances Filtration

polymer candle filter is a critical component used in the chemical fiber industry for polymer melt filtration work. Polymer melt is the molten form of synthetic polymers, which is used to produce various types of chemical fibers like polyester, nylon, and acrylic.

The main purpose of melt filter element is to remove impurities, such as solid particles and contaminants, from the polymer melt before it is further processed into fibers. These impurities can negatively affect the quality of the final chemical fibers and cause production issues like unevenness, defects, and reduced mechanical properties.

    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.
