Product description

Lvyuan sintered pe filters use a sinter material with a molecular weight of 3 million or more. After being sieved, the pressure inside the mold with internal and external mirrors is placed in the sintering furnace at a certain temperature.

A certain sintering holding time, made from baked out, baked, and film, ultra-high-molecular-weight polyethylene has better acid and alkali resistance than ordinary polyethylene.

Below 80 °C, its acid and alkali resistance is comparable to PTFE, and its rigidity and flexibility are better than those of ordinary polyethylene. Hole forming mechanism: Similar to powder metallurgy porous materials, microspores are formed by bridging between particles.

The micro-diameter structure is a labyrinth structure with multiple holes superimposed to form the final filter aperture.

Sintered Pe Filter Proper usage or Effective application

Lvyuan sintered polyethylene PE pipe or plate can be used for vacuum filtration, pressure filtration, or gravity filtration. In order to use this product well, the following points must be mastered:

01

Correct selection of filtration parameters (optimum filtration pressure difference, filtration speed, filtration area, etc.) means that a small test to determine the design parameters must be carried out in advance.

02

According to the requirements for filtration in production and the characteristics of porous PE media, the mechanical structure of the filter should be correctly designed.

03

According to the characteristics of different materials, different regeneration operation procedures should be formulated.

04

The PE Sintered Filter should be equipped with a certain volume of air bags (one air bag can be used for several filters) for back-blow slag removal and back-blow regeneration. The back-blow pipeline should be thicker and the back-blow valve Ball valves or cocks should be used, the blowback speed should be fast, and the blowing time should not be long, generally no more than 1 second, otherwise the compressed air will be wasted.

05

There must be certain operating procedures during use, especially at least 5–10 minutes of low-pressure (0.3-05) kg/s filtration at the start-up stage. It is forbidden to reach the normal operating pressure as soon as it is started; otherwise, the capillary pores will be blocked too quickly, which will significantly reduce productivity.

Porous Plastic Filter

How do I clean and maintain sintered porous filter discs?

Cleaning methods depend on the material used. For metal discs, methods may include backwashing, ultrasonic cleaning, or chemical cleaning. Polyethylene discs are often cleaned with mild detergents. Regular maintenance ensures a prolonged operational life.

How to Calculate Filter Porosity?

Filter porosity is classified into three major types: Primary Porosity, Secondary Porosity, and Effective Porosity. The calculation involves determining the ratio of the volume of gaps in the filter to the total volume, expressed as a percentage.

Porosity = (Volume of Empty Gaps/Total Volume of Filter) x 100

Other methods include:

• Direct Methods: Calculate the entire volume of the porous filter and the volume of a skeletal filter (without pores) to find the porosity.

• Computed Methods: Use modern computer technology to obtain a 3D image of a porous filter and employ defect analysis techniques.

• Water Evaporation Technique: Calculate porosity by determining the difference in weight between the saturated filter in water and the dried filter.

What is Porosity in Filtration?

Porosity, in the context of filtration, measures the pores on the filter surface, determining its efficiency and capabilities. Higher porosity indicates more open structures (pores), allowing maximum flow with minimal pressure drops.

However, it's crucial to note that a higher porosity rate doesn't necessarily guarantee greater efficiency. When selecting the right material for your porous metal filter, consider aspects such as pore size, pressure drop, temperature resistance, and strength.

• Size of Pores: Micron rating is crucial. A material rated at 5 microns will likely stop particles of 5 microns or larger.

• Pressure Drop: Choose a material with a minimum pressure drop for uniform flow.

• Temperature Resistance: Analyze the material's capability to perform efficiently under specific temperatures.

• Strength: Opt for a filter with the strength to withstand changing environmental conditions.

How do I choose the right sintered porous filter disc for my application?

Consider factors such as the nature of the substances being filtered, operating conditions (temperature, pressure), chemical compatibility, and desired filtration precision. Consulting with filtration experts can help guide the selection process.

In what industries are sintered porous filter discs commonly used?

They are widely used in industries such as petrochemicals, pharmaceuticals, water treatment, food and beverage, automotive, and more, owing to their versatility and effective filtration capabilities.

What is a sintered plastic porous filter?

A sintered plastic porous filter is a filtration device made from polymeric materials that are compressed and heated to form a porous structure with controlled pore sizes and distribution.
