Filter cloth, made from synthetic fibers, may crack under extreme conditions. The main causes include severe physical wear, chemical corrosion, sudden temperature changes, design flaws, improper installation, and improper operation.
Physical Wear: Prolonged contact with materials, especially those with high flow rates, high pressures, or containing hard particles, leads to abrasion and friction on the filter cloth surface, causing significant wear and eventually cracking.
Chemical Corrosion: Certain filter cloth materials are corrosive, and long-term exposure can erode the fibers of the filter cloth, reducing its strength and leading to cracking.
Temperature Effects: Prolonged exposure to high temperatures or sudden temperature changes can cause thermal aging of the filter cloth material, reducing fiber strength, increasing brittleness, and making it prone to breaking.
Design Flaws and Improper Installation: Mismatching the filter cloth with the equipment or improper installation, such as uneven tension or poor edge treatment, can contribute to cracking. For instance, wrinkles during installation can lead to folds that are vulnerable to damage during filtration.
Improper Operation: Actions such as excessive force during cleaning, frequent equipment start-stop cycles causing shock loads, or improper tension settings can damage the filter cloth, eventually causing cracks. Inadequate tension settings on the equipment may also lead to cracking.
Therefore, to prevent filter cloth cracking, it is essential to select the right filter cloth, optimize equipment design, and ensure proper installation and maintenance. Additionally, aged or worn filter cloths should be replaced in a timely manner to avoid production issues and environmental contamination caused by cracking.
