Technical Analysis: Moisture Requirements for Liquid Filter Bag Filtration
2026-07-03
When liquid filter bags work in wet aqueous environments, six core factors determine filtration stability and service life. Tianshan Filter sorts out clear selection & operation standards for industrial buyers.
Six Core Requirements
-
Filtration Efficiency Consistently trap particles and microbes; maintain stable performance without rapid clogging during long operation.
-
Filtration Accuracy Match micron rating to target impurities. Smaller pores deliver higher precision yet higher resistance. Verify real accuracy instead of only nominal data.
-
Material Compatibility Resist acid, alkali and salt corrosion. Choose high-temperature resistant media for hot liquid working lines.
-
Water Resistance (Critical) Pick low-water-absorption fiber to avoid swelling. Anti-hydrolysis material prevents fiber embrittlement after long soaking.
-
Operating Environment Adaptability Withstand system pressure and flow without deformation. High temperature & humidity accelerate fiber aging and mold growth.
-
Maintenance & Storage Clean regularly to restore throughput; replace damaged bags timely. Store sealed in cool, dry areas away from sunlight and rain.
Material Water Absorption Hydrolysis Resistance Chemical Range Max Temp PP Very low Excellent pH 1–13 95℃ Polyester Medium Good pH 3–11 140℃ Nylon High Fair pH 4–10 120℃ PTFE Near zero Best pH 0–14 260℃ We supply customized moisture-resistant liquid filter bags (0.5–300μm) with gradient depth felt and leak-free ultrasonic seams.
