PP Melt Blown Filter Cartridge - Micron - Level Fine Filtration & Economical and Durable Choice Product Introduction Structural Composition Melt - Blown Filter Media: Made of 100% polypropylene (PP) raw materials, through processes such as high - temp

Product Introduction

1. Structural Composition

• Melt - Blown Filter Media: Made of 100% polypropylene (PP) raw materials, through processes such as high - temperature melting, spinning, drawing, and receiving molding, a filter media with a unique three - dimensional tortuous channel is formed. The pore size gradually decreases from the outside to the inside, achieving deep - layer filtration.

• Central Rod and End Caps: The central rod is generally made of PP, providing structural support. The end caps are made of PP or other corrosion - resistant materials, closely connected to the central rod and filter media to ensure the overall sealing of the filter cartridge.

• Sealing Rings: Made of materials such as silicone rubber and ethylene - propylene - diene monomer rubber, installed at both ends of the filter cartridge to ensure a good seal when the filter cartridge is connected to the filtration equipment and prevent liquid bypass.

2. Working Principle：The liquid to be filtered enters from the outside of the filter cartridge. Under pressure, it passes through the multi - layer pore structure of the melt - blown filter media. Due to the gradually decreasing pore size from the outside to the inside of the filter media, large - particle impurities are first intercepted by the outer layer, and smaller particles are captured by the middle and inner layers during the inward penetration process. This effectively removes impurities such as suspended solids, colloids, and microorganisms in the liquid, and finally outputs clean liquid.

3. Core Advantages：Compared with filter cartridges of other materials, PP melt - blown filter cartridges are made of pure PP raw materials without additives, with good chemical stability and no pollution to the filtered liquid. The unique deep - layer filtration structure gives it a large dirt - holding capacity and a long service life. It has a lower cost and high cost - performance, making it suitable for scenarios sensitive to filtration costs.

Working Process

1. Installation Preparation

• Check the appearance of the filter cartridge to ensure that there is no damage or deformation, and the end caps and sealing rings are intact.

• Select a suitable specification of PP melt - blown filter cartridge according to the requirements of the filtration equipment and prepare the installation tools.

2. Filter Cartridge Installation

• Close the inlet and outlet valves of the filtration equipment and empty the residual liquid in the equipment.

• Gently insert the filter cartridge into the filter cartridge installation seat of the filtration equipment, ensure that the sealing ring is correctly installed and in the right position. Tighten the end cap or use other fixing methods to fix the filter cartridge, ensuring a firm connection and good sealing.

3. Filtration Operation

• Slowly open the inlet valve of the filtration equipment to allow the liquid to be filtered to flow into the equipment slowly. After exhausting the air in the equipment, close the exhaust valve.

• Observe the pressure gauge value to ensure that the operating pressure is within the rated range of the filter cartridge (generally ≤0.4MPa). Open the outlet valve to start normal filtration. The filtered clean liquid flows into subsequent processing or use processes.

4. Filter Cartridge Replacement

• When the pressure difference between the inlet and outlet of the filtration equipment exceeds the set value (such as 0.15 - 0.2MPa), or reaches the preset service duration (such as 1 - 3 months, depending on actual working conditions), it indicates that the filter cartridge needs to be replaced.

• Close the inlet and outlet valves, open the drain valve to empty the liquid in the equipment, disassemble the end cap of the filter cartridge, and remove the old filter cartridge.

• Install a new PP melt - blown filter cartridge, repeat the installation steps, restart the filtration equipment, and resume the filtration work.

FAQ

1. How to choose the appropriate precision of PP melt - blown filter cartridges according to actual needs?：The selection of filter cartridge precision needs to comprehensively consider the initial impurity conditions of the filtered liquid and the requirements of subsequent processes for liquid cleanliness. For example, for domestic drinking water filtration, a precision of 1 - 5 microns is generally sufficient to remove most visible impurities and some microorganisms. In the preparation of high - purity water in the electronics industry, filter cartridges with a precision of 0.1 - 1 micron are required to meet the extremely high purity requirements for water quality. If there are many impurities in the liquid, a filter cartridge with a lower precision can be used for pre - filtration first, and then a filter cartridge with a high precision for secondary filtration.

2. What should I do if the flow rate drops significantly during the use of PP melt - blown filter cartridges?：A significant drop in flow rate may be due to severe blockage of the filter cartridge. At this time, check the pressure difference between the inlet and outlet of the filtration equipment. If it exceeds the set value, the filter cartridge needs to be replaced in a timely manner. It may also be that the impurity particles in the filtered liquid are relatively large, causing the filter cartridge to block quickly. A pre - filtration device can be added at the front end. In addition, check whether the equipment pipeline is blocked, whether the valves are fully opened, and whether the sealing ring is aged, resulting in liquid bypass, and deal with the specific problems accordingly.
