OEM Polymer Melt Filter Elements SUS 304 Factory, Company

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.

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.

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 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.

Core Advantages of POLYMER Melt Filters

1
It can effectively filter out gel particles, carbonized impurities, catalyst residues, dust and other tiny particles in the melt.
2
Enhance the mechanical properties and appearance of the product.
3
It has a high dirt-holding capacity and can hold a large amount of pollutants before being completely clogged, thereby significantly extending the replacement cycle.
4
It has reduced the downtime caused by replacing filters or cleaning equipment, and improved the utilization rate and overall efficiency of the production line.
5
It provides stable and consistent filtration resistance, which helps maintain the stability of melt pressure, flow rate and temperature, making the entire production process more controllable and smoother.
6
High temperature and high pressure resistance. It is usually made of stainless steel (such as 304, 316L), Hastelloy and other metals.

Application Areas

1. Petrochemical

Refining, chemical production and separation and recovery of intermediate products.

2. Metallurgy

Used for filtration of hydraulic systems of rolling mills and continuous casting machines.

3. Textile

Purification and uniform filtration of polyester melt during the drawing process.

How to Clean Industrial Filter Cores?

Industrial fine filters are widely used in industries such as pharmaceutical, chemical, ink and paint, food and beverage, automobile manufacturing, cement industry, petroleum, oil refineries, petrochemical, etc. It is important to clean these filter cartridges to ensure that they filter consistently over a long period of time.

Industrial filter cores provided by Song Phung have high dirt holding capacity, are easy to install, clean and maintain. The fine filter element is sturdy, has a solid quality core and has well-formed layers, so cleaning and installing them is very easy.

Some filtration systems allow backwashing and have a CIP system design. But most have to be taken out of their shells, sterilized and washed. When not in use, these cleaned filter cartridges are dried and sealed or vacuumed to prevent contamination or wear.

Frequently Asked Questions (FAQ)

Q: What is the primary function of a polymer melt filter element?
The polymer melt filter element is installed in extrusion lines to remove gel particles, carbonized impurities, catalyst residues, and dust from high-temperature polymer melt, ensuring superior final product quality and protection for downstream components.
Q: What filter media materials are used in pleated candle filters?
They mainly utilize stainless steel wire mesh (SUS304 or 316L) for easy cleaning and long operational cycles, or high-porosity stainless steel sintered fiber for deep filtration and enhanced dirt-holding capacity.
Q: What operating conditions can these melt filter elements withstand?
Our industrial candle filter elements can withstand high working temperatures up to ≤350°C and handle an allowed pressure difference up to 10 bar (140 psi).
Q: Are custom dimensions and connector types available?
Yes, custom candle filters can be tailored to your requirements with filter lengths from 16 to 60 inches (406.4–1524mm) and various standard connector types including 222, 226, 215, M36, M28, M24, M22, and M20.
Q: How can industrial candle filter elements be cleaned and regenerated?
Filter elements can be cleaned using integrated CIP backwashing systems or removed from housings for chemical solvent cleaning, ultrasonic bath treatment, or thermal calcination, allowing multiple regeneration cycles.
