1、 Filtration efficiency

Efficient filtration: The liquid filter bag should be able to efficiently filter out harmful substances such as impurities, particles, and microorganisms in the water, ensuring that the filtered water quality meets the requirements for use. Efficient filtration efficiency is one of the important indicators for evaluating the performance of liquid filter bags.

Continuous stability: During long-term use, the liquid filter bag should be able to maintain stable filtration efficiency, avoiding a decrease in filtration effect due to blockage, wear, and other reasons.

2、 Filtering accuracy

Aperture control: The aperture size of the liquid filter bag should be selected according to actual needs to ensure that impurities of the target size can be intercepted. Generally speaking, the smaller the aperture, the higher the filtration accuracy, but it may also increase filtration resistance and cost.

Accuracy calibration: Due to differences in materials and production processes, the actual filtration accuracy of liquid filter bags may deviate from the nominal value to some extent. Therefore, when choosing a filter bag, it is important to understand its actual filtration efficiency and consider it in conjunction with specific application scenarios.

3、 Material compatibility

Corrosion resistance: Liquid filter bags should be able to withstand chemical substances that may exist in moisture, such as acids, alkalis, salts, etc., to avoid damage or performance degradation of the filter bag due to corrosion.

High temperature resistance: For liquid filter bags that need to be used in high temperature environments, materials with high temperature resistance should be selected to ensure their stability and service life.

4、 Water resistance

Water absorption: Some liquid filter bag materials may have a certain degree of water absorption, which may affect their filtration efficiency and stability. Therefore, when choosing filter bags, attention should be paid to their water absorption indicators and materials with lower water absorption should be selected.

Hydrolysis resistance: Some materials may undergo hydrolysis reactions after prolonged contact with water, leading to a decrease in performance. Therefore, it is necessary to choose liquid filter bag materials with good hydrolysis resistance.

5、 Usage environment

Pressure and Flow: The liquid filter bag should be able to withstand the pressure and flow requirements during use, avoiding damage or deformation of the filter bag due to excessive pressure or flow.

Temperature and humidity: The temperature and humidity in the usage environment may also affect the performance of liquid filter bags. For example, high temperature environments may accelerate the aging of filter bags, while high humidity environments may cause condensation or mold on filter bags.

6、 Maintenance and upkeep

Cleaning and replacement: Liquid filter bags will gradually accumulate impurities and dirt during use, affecting their filtration efficiency. Therefore, it is necessary to regularly clean the filter bag to restore its filtering performance. When the filter bag is damaged or the filtration efficiency significantly decreases, a new filter bag should be replaced in a timely manner.

Storage and Preservation: During the storage and preservation process, the filter bag should be protected from adverse factors such as direct sunlight, rain, and moisture to maintain its performance and extend its service life.

The requirements for liquid filter bags in filtering moisture are multifaceted, including filtration efficiency, filtration accuracy, material compatibility, water resistance, usage environment, and maintenance. When selecting and using liquid filter bags, these factors should be fully considered to ensure that they can meet practical needs and achieve good filtration effects.
