1、 Preparation stage

Choose the appropriate filter material:

The core filter material of nylon folding filter cartridge is nylon (NY6) microporous filter membrane. Nylon membrane, as one of the longest surviving synthetic fibers, has excellent chemical stability and physical properties, making it an ideal material for making filter cartridges.

Nylon membrane has a natural positive charge under neutral pH conditions, which makes it highly efficient in retaining particles and bacteria, making it a cost-effective sterilization grade filter with absolute accuracy and 100% retention rate on the market.

Preprocessing:

Perform necessary pre-treatment operations such as cleaning, drying, and disinfection on nylon filter materials to ensure the initial cleanliness and sterility of the filter element.

2、 Filter forming and packaging

Filter forming:

Fold the pre treated nylon filter material according to the designed shape and size to form the initial form of the filter element. This step is the key to the production of the filter element, which determines the filtering area and shape of the filter element.

The folding structure of the filter element greatly increases the filtration area, thereby improving the filtration efficiency and pollutant holding capacity.

Encapsulation and fixation:

Insert the folded filter element into the housing and seal and fix it using hot melt welding technology. This adhesive free and foreign object free packaging method ensures the sealing and integrity of the filter element.

During the process of combining filter elements, all parts are welded using adhesive free hot melt welding technology to form a complete integrated filter element without chemical pollutants.

3、 Filtering process

Filtering principle:

The filtration principle of nylon folding filter cartridge is mainly achieved through the pore size and surface area of the filter material. The pore size of the filter material determines the particle size it can filter out, while the surface area of the filter material determines the amount of water it can filter.

When water flows through the folding filter element, impurities, particles, microorganisms and other substances in the water will be trapped inside the filter element by the filter material, while clean water will flow out through the pores of the filter element.

Efficient filtration:

Due to the large filtration area, low initial pressure difference, and fast flow rate of the nylon folding filter element, it has efficient filtration performance. It can effectively remove harmful substances such as small particles, bacteria, viruses, etc. from water, ensuring the safety of the effluent water quality.

4、 Subsequent processing and testing

Integrity testing:

Conduct strict integrity testing on the made nylon folding filter cartridge to ensure its quality and performance meet the requirements. Integrity testing can detect indicators such as the sealing, filtration accuracy, and dust holding capacity of the filter element.

Packaging and Storage:

Pack the qualified filter cartridges for transportation and storage. During the packaging process, it is important to avoid contaminating and damaging the filter element.

The filtration process of nylon folding filter includes multiple steps such as preparation stage, filter forming and packaging, filtration process, and subsequent processing and testing. These steps together ensure the efficient filtration performance and long-term stability of the filter cartridge.
