To ensure the efficient filtration and prolong the service life of industrial filter cloths during use, it is essential to pay close attention to the following key issues:
Material adaption:
Select temperature and corrosion resistant materials(such as polyester acid-resistant, polypropylene alkali-resistant, nylon abrasion-resistant) according to the working conditions.
Filtration accuracy:
Choose the pore size based on the size particle of particles to avoid clogging or leakage.
Temperature and chemical environment:
High temperature filter cloth (e.g. PTFE) should be selected for high temperature environments, and Teflon-coated filter cloth should be used for strong corrosive environments.
Correct Installation
Flat and wrinkle-free:
Ensure the filter cloth is evenly tensioned during installation to avoid folding that could lead to breakage or leakage.
Sealing check:
Special clamps or adhesive strips can be used to seal the edges, thus preventing bypass leakage.
Regular Maintenance and Cleaning
Cleaning method:
To avoid fibre damage from high-pressure water jets, we recommend the use of a low-pressure backwash or neutral detergent soak.
Regular inspection:
It is important to check the filter cloth regularly for wear and holes and to ensure that it is repaired or replaced as required.
Proper Storage
To ensure optimal quality and longevity, filter cloth should be stored in a cool and dry place to avoid UV-induced ageing. It is also important to store it flat to prevent folding and indentation, as this can lead to structural damage.
Usage log:
Record the time taken to replace filter cloth, any failure phenomena you observe and the treatment measures taken, and analyse the reasons for failure.
Performance optimization:
Adjust parameters (e.g. filtration cycle, backwash frequency) through data to reduce costs.
Food-grade/Pharmaceutical-grade:
Choose filter materials approved by FDA.
High-temperature working environment:
The use of glass fibre or metal fibre filter cloth ensures resistance to sustained high temperatures.
These measures have been shown to enhance filter cloth efficiency, reduce replacement frequency, and ensure production safety and environmental compliance.
