Wet Strength Filter Papers suitable for filtering aqueous liquids
High-grade filter papers are indispensable for routine work in laboratory and industrial applications.
Great Wall can supply you with a broad range of filter papers for myriad filtration tasks and support you in solving all your filtration challenges.
Industrial Filter Papers Introduction
Great Wall industrial filter papers are versatile, strong, and cost-effective.7 types are available classified by strength, thickness, retentivity, creping, and holding capacity. Suitable grades for many industries are available in creped and smooth surfaces and consisting of 100% cellulose or with an incorporated resin to increase wet strength.
Wet Strength Filter Papers
Great Wall provides a range of wet-strengthening qualitative filter papers containing a small amount of chemically stable resin to improve high wet-strength.Recommended for the purification and regeneration of electroplating baths.This kind of paper with high wet strength and has a large range of interception accuracy.Also used as a protective paper in filter presses.
Applications
Great Wall filter paper includes grades suitable for general coarse filtration, fine filration, and retention of specified particle sizes during the clarification of various liquids. We also offer grades that are used as a septum to hold filter aids in a plate and frame filter presses or other filtration configurations, to remove low levels of particulate, and many other applications.
Such as: production of alcoholic, soft drink, and fruit juice beverages, food processing of syrups, cooking oils, and shortenings, metal finishing and other chemical processes, refinement and separation of petroleum oils and waxes.
Please refer to the application guide for additional information.
