OEM Candle Filter Cartridge and Filter Elements for Polymer Manufacturer, Companies

Candle Filter Elements are groups of metal pleated filter elements fixed with candle holders to work as an candle-like filtration unit. Porous metal filters for high-temperature, high pressure polymer processing applications. Designed to remove the impurities ( such as titanium dioxide, gels and other solid residues ) of the polymer melt in chemical fiber, textile and plastics industries. Suitable for monomer, pre-polymer or polymer filter systems.These filter elements are typically tubular and made of stainless steel mesh or stainless steel sintered mesh with a cap on the bottom and a threaded connector on the top (or vice versa) that connects to the core end. The outer surface of some tubes is made of perforated metal sheet, expanded metal, sintered metal or porous ceramic to support the filter media.

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 candle filter element is placed inside the filter housing (housing). It is a compact device that can typically hold 1-20 candles, depending on the size of the filter. The filter element is arranged vertically in the pressure vessel to filter liquids with low solid content. The candle filter allows high productivity, easy bottom sediment discharge.

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.
