Famous Polymer Candle Filter for High Viscosity Substances Filtration Factory, Company

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.

Product Description

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 (FAQ)

What is the primary function of a melt filter element?

The melt filter element is installed in extrusion lines to filter out impurities from polymer melt before spinning, ensuring continuous operation, improved product quality, and protection for downstream machinery.

What materials are used to manufacture these polymer filters?

They are manufactured using high-grade SUS304 or SUS316L stainless steel, with media options including metal sintering mesh and stainless steel wire mesh for superior durability.

Why choose a folded/pleated candle filter design over cylindrical types?

The folded/pleated filter design offers a filtration surface area that is 3 to 5 times larger than traditional cylindrical filters, allowing for greater dirt holding capacity and longer operation cycles.

Can the melt filter element be cleaned and reused?

Yes, these elements are built for high temperature and corrosion resistance, enabling them to be thoroughly cleaned and reused multiple times to reduce operating costs.

What operating temperatures and pressures can this filter handle?

The main feature working temperature range is -60℃ to 500℃ (with typical continuous working temperatures up to ≤350℃ depending on media type), withstanding a maximum pressure differential of up to 10MPa (10 bar / 14psi allowed operational pressure difference).

Are custom sizes and connectors available for specific machinery?

Yes, custom high-quality polymer pleated candle filters can be tailored to meet specific industrial requirements, supporting standard connector types including 222, 226, 215, M36, M28, M24, M22, and M20.
