V. Food processing industry

1. In the food processing process, such as flour processing and candy manufacturing, a large amount of food dust will be generated. The coated polyester fiber filter cartridge dust collector can be used in the ventilation and dust removal system of the food processing workshop to ensure the cleanliness and hygiene of the food production environment and prevent dust from polluting food.

2. For some food processing that requires high cleanliness, such as pharmaceuticals and health products, the coated polyester fiber filter cartridge dust collector can provide efficient filtration performance and meet strict hygiene standards and quality requirements.

The following are some materials that can be used to make coated polyester fiber filter cartridges:

I. Polyester fiber substrate

1. Characteristics:

   - High strength: It has high tensile strength and toughness, can withstand certain pressure and mechanical impact, and ensure that the filter cartridge is not easily damaged during use.

   - Good chemical corrosion resistance: It has certain tolerance to most acids, alkalis, organic solvents, etc., and can be used in relatively harsh industrial environments.

   - Thermal stability: It maintains stable performance within a certain temperature range and is not easily deformed or melted.

   - Strong processability: It is easy to be processed into filter cartridges of various shapes and sizes to meet the needs of different equipment and processes.

2. Selection criteria:

   - Fiber fineness: Finer fibers can provide a larger filtration area and higher filtration efficiency.

   - Fiber length: Moderate fiber length can ensure the strength and stability of the filter material and is convenient for processing at the same time.

   - Porosity: Appropriate porosity can reduce filtration resistance and improve air circulation while ensuring filtration efficiency.

II. Coating material

1. PTFE (polytetrafluoroethylene) film:

   - Characteristics:

     - Extremely low surface energy: It is non-sticky, and dust is not easily adhered to the film surface. It is easy to clean the ash and can maintain the long-term stable filtration performance of the filter cartridge.    

       - Excellent chemical stability: It is resistant to strong acids, strong alkalis, organic solvents, etc., and is suitable for various complex industrial environments.

       - High filtration accuracy: It can effectively filter tiny particles, and the filtration efficiency for particles above 0.3 microns can reach more than 99.99%.

       - High temperature resistance: It can be used for a long time in the temperature range of -200℃ to 260℃.

   - Selection criteria:

       - Film thickness: Appropriate thickness can ensure the strength and filtration performance of the film without increasing excessive filtration resistance.

       - Coating process: A good coating process can ensure that the film is firmly combined with the polyester fiber substrate and is not easily peeled off.

2. PPS (polyphenylene sulfide) film:

   - Characteristics:

       - Corrosion resistance: It has good tolerance to acids, alkalis, oxidants, etc., and is especially suitable for industries such as chemical and electric power.

       - High temperature resistance: It can be used for a long time at a temperature of about 190℃, and the instantaneous temperature resistance can reach 240℃.

       - Flame retardancy: It has self-extinguishing property and is not easy to burn, which improves the safety of the filter cartridge in high temperature and flammable environments.

       - Good mechanical properties: High strength and good wear resistance can extend the service life of the filter cartridge.

   - Selection criteria:

       - Film quality: Select a PPS film with stable quality and reliable performance to ensure filtration effect and service life.

       - Compatibility with polyester fiber: There should be good adhesion between the film and the polyester fiber substrate to avoid delamination during use.

3. ePTFE (expanded polytetrafluoroethylene) film:

   - Characteristics:

       - Three-dimensional microporous structure: It has extremely high porosity and air permeability, low filtration resistance, and good air circulation.

       - Surface filtration mechanism: It mainly filters through the micropores on the film surface, and dust is intercepted on the film surface and is easy to clean.

       - Waterproof property: It has good waterproof performance and can prevent moisture from entering the filter cartridge and affecting the filtration effect.

       - Softness: It has a soft texture and is easy to process and install, and can adapt to filter cartridges of different shapes and sizes.

   - Selection criteria:

       - Micropore size: Select an appropriate micropore size according to different filtration needs to ensure filtration accuracy and efficiency.

       - Film strength: Although the ePTFE film is soft in texture, it still needs to have a certain strength to ensure that it is not easily damaged during use.
