Melt Polymer Candle Filter for High Viscosity Substances Filtration

A melt polymer candle filter is a critical component used in the chemical fiber industry for filtering polymer melt. 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 a 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.
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.

Melt Polymer Candle Filter

Melt filter element is an all-metal filter element welded by argon arc welding. The filter layer adopts a multi-pleat structure folding process, with uniform pore size distribution and increased filtering area. The metal pleated filter is made entirely of stainless steel, with no leakage or medium shedding. In high pressure environments, the stainless steel pleated filter adopts a skeleton design. The inner and outer skeleton greatly enhances the pressure resistance of the metal pleated filter element. The main filter layer of Pleated Filter mainly uses two materials：stainless steel wire mesh and stainless steel Sintered fiber . Stainless steel wire mesh is woven from stainless steel wire. Its pleated filter has the characteristics of smooth pores, easy cleaning, high temperature resistance, corrosion resistance, no wire mesh falling off, and long filtration cycle. Stainless steel sintered fiber is a porous deep filter material made of stainless steel fibers sintered at high temperature. Its pleated filter has the characteristics of high porosity, good air permeability, strong dirt holding capacity, and strong regeneration ability.

Melt filter element is a filtration device widely used in the chemical fiber industry for polymer melt and other high-viscosity substances. Its function is to remove solid impurities such as carbonized particles and metal oxides in the melt, improve the purity of the melt, provide qualified raw materials for downstream processes, and ensure the normal operation of the melt filter.
