Q1: What makes polypropylene filter cloth suitable for alkaline materials?
Polypropylene has excellent chemical resistance to alkaline substances, making it ideal for industries processing materials with high pH levels. It maintains structural integrity and filtration efficiency even when exposed to strong alkalis over extended periods.
Q2: What is the typical lifespan of polypropylene filter cloth?
The service life depends on operating conditions, but properly maintained polypropylene filter cloth typically lasts 6-18 months in standard industrial applications. Regular cleaning and proper handling can significantly extend its useful life.
Q3: How do I clean polypropylene filter cloth?
For optimal performance, clean using:
- Low-pressure water spray for initial cake removal
- Mild detergent solutions for stubborn residues
- Thorough rinsing with clean water
- Proper drying before storage or reuse
Avoid harsh chemicals that might damage the cloth structure.
Q4: Can polypropylene filter cloth be used for high-temperature applications?
Polypropylene filter cloth is not recommended for temperatures exceeding 90°C. For higher temperature applications, alternative materials like polyester or PTFE should be considered.
Q5: What is the minimum particle size that can be filtered?
Our polypropylene filter cloth can achieve filtration precision below 1 micron, making it suitable for fine particle separation in demanding applications.
Q6: Is polypropylene filter cloth food-grade compliant?
Yes, our food-grade polypropylene filter cloth meets relevant regulatory standards for food processing applications, ensuring safe contact with food products.
