In the realm of filtration technology, the PP microporous folded filter element stands out as a high - performance product, catering to a wide range of industries with its advanced design and excellent filtration capabilities.

I. Product Introduction

The PP microporous folded filter element is crafted with precision using high - quality polypropylene materials. It is composed of a microporous polypropylene fiber membrane, which is the core of its filtration function, along with non - woven fabric or wire mesh as the inner and outer support layers. These components are ingeniously folded to form a compact yet highly efficient structure.

The filter element's housing, central rod, and end caps are processed through advanced hot - melt welding technology. This manufacturing method ensures that no adhesives are used during production, effectively eliminating the risk of leakage and secondary pollution. This not only guarantees the integrity of the filtration process but also makes the filter element an ideal choice for applications where high - purity filtration is crucial.

Available in various standard sizes, the filter element can be customized in terms of length (such as 5", 10", 20", 30", 40") and diameter (outer diameter: 69mm, 83mm, 131mm; inner diameter: 28mm - 40mm), allowing for seamless integration into different filtration systems.

II. Working Principle

When the fluid to be filtered enters the PP microporous folded filter element, it first encounters the outer support layer. This layer serves as a preliminary barrier, catching larger particles and preventing them from clogging the more delicate microporous membrane. As the fluid continues to flow through the folded structure, it passes across the surface of the microporous polypropylene fiber membrane.

The microporous membrane, with its precisely controlled pore size, plays a pivotal role in the filtration process. Larger particles are mechanically sieved and blocked by the membrane pores. Smaller particles, which may be in the sub - micron range, are removed through a combination of interception and diffusion mechanisms. Due to the Brownian motion of these fine particles, they randomly collide with the membrane surface and are adsorbed, effectively removing them from the fluid stream.

The unique folded design significantly increases the surface area of the filter media. This means that more fluid can be processed simultaneously, enhancing the filtration efficiency while maintaining a relatively low pressure drop across the filter element. As a result, a clean, filtered fluid is obtained at the outlet, free from impurities and contaminants.

V. Application Fields

1. Pharmaceutical Industry

• Liquid Filtration: Used for the pre - filtration of various pharmaceutical liquids, such as antibiotic solutions, injectable medications, and pharmaceutical raw material solutions. The high - precision filtration of the PP microporous folded filter element helps to remove impurities, microorganisms, and particulate matter, ensuring the quality and safety of pharmaceutical products.

• Sterile Filtration: In the production of sterile pharmaceutical products, the filter element plays a crucial role in achieving sterile filtration. It can effectively remove bacteria and other microorganisms, meeting the strict sterility requirements of the pharmaceutical industry.

2. Food and Beverage Industry

• Beverage Filtration: Applied to filter beverages like beer, wine, fruit juice, and soft drinks. By removing particles, yeast cells, and other impurities, it enhances the clarity, taste, and shelf - life of the products. For example, in beer production, the filter element helps to clarify the beer and remove any suspended solids, resulting in a more visually appealing and better - tasting product.

• Water Filtration for Production: Filters the water used in food and beverage production processes. This ensures that the water is free from contaminants, preventing any negative impact on product quality and safety. In the production of bottled water, the filter element can effectively remove impurities and microorganisms, providing clean and safe drinking water.

3. Petroleum Industry

• Oilfield Water Injection Filtration: In oilfield operations, the filter element is used to filter the water injected into oil wells. By removing impurities such as sand, silt, and bacteria, it helps to prevent the clogging of injection wells and the corrosion of pipelines, improving the efficiency of oilfield water injection and extending the service life of equipment.

• Crude Oil Filtration: Can be used for the filtration of crude oil to remove solid particles and impurities, which is beneficial for subsequent oil refining processes. Removing these impurities can reduce the wear and tear of refining equipment and improve the quality of refined oil products.

VI. FAQ

1. How do I select the appropriate filtration precision for my application?

The choice of filtration precision depends on the nature of the particles you need to remove and the specific requirements of your process. For applications where extremely fine - particle removal is critical, such as in the pharmaceutical and electronics industries, a lower filtration precision (e.g., 0.1 - 1μm) is recommended. For general - purpose filtration in industries like food and beverage or petroleum, a higher filtration precision (e.g., 5 - 50μm) may be sufficient. It is advisable to consult our technical team, who can analyze your application details and recommend the most suitable filtration precision.

2. What is the expected service life of the PP microporous folded filter element?

The service life of the filter element varies depending on factors such as the quality of the fluid being filtered, the flow rate, and the operating conditions. In relatively clean fluid applications with normal flow rates, a filter element may last 3 - 12 months. However, in more contaminated environments or high - flow applications, the service life may be shorter. Regular monitoring of the pressure drop across the filter element can help determine when it needs to be replaced.

3. Can the PP microporous folded filter element be used in high - temperature applications?

The maximum operating temperature of the standard PP microporous folded filter element is ≤80℃ at 0.1Mpa. For applications with higher temperatures, special - grade filter elements or additional cooling measures may be required. It is important to specify your operating temperature requirements when ordering to ensure that the filter element can withstand the intended operating conditions.

VII. Conclusion

The PP microporous folded filter element is a reliable, high - performance filtration solution that offers excellent chemical compatibility, high - efficiency filtration, and a long service life.
