Rubber coated filter cloth and plate & frame filter cloth play an important role in the filtration industry. Although they have similar functions, they are different in material, structure, performance and application.
Material and Structure
Rubber coated filter cloth, as the name implies, is a composite material made by attaching a rubber layer to its surface through a specific process on the basis of filter cloth.
In contrast, plate & frame filter cloth is a flat filter material interwoven with multiple layers of fibers or yarns. Its material is relatively simple, and it mainly relies on the physical properties and chemical stability of fibers or yarns to achieve the filtering function.
Performance Characteristics
Filtration performance: The rubber layer attached to the surface of the rubber coated filter cloth can effectively prevent the penetration of particles and the leakage of filtrate, which is conducive to the formation and shedding of filter cakes. The multi-layer fiber structure of the plate & frame filter cloth can form a relatively tight filter layer, and has a strong interception ability for tiny particles.
Durability: The durability of the rubber coated filter cloth is mainly due to the protection of its rubber layer, which can effectively resist the damage of external factors such as wear, corrosion and stretching. The plate & frame filter cloth is relatively worse and is easily damaged by factors such as material impact, friction and corrosion.
Cleaning and maintenance: Due to the presence of the rubber layer, the rubber coated filter cloth is not easy to be damaged during the cleaning process and is easy to restore the original filtering performance. Due to the complexity of the fiber structure of the plate & frame filter cloth, special attention should be paid to avoid damage during the cleaning process.
Application Field
The rubber coated filter cloth is mainly suitable for occasions that require high filtering accuracy, high durability and easy cleaning and maintenance, such as solid-liquid separation processes in chemical, pharmaceutical, food and other industries. The plate & frame filter cloth is more suitable for occasions that do not require high filtering accuracy but have high requirements for filtering area and filtering speed, such as wastewater treatment and solid waste recycling processes in environmental protection, metallurgy, mining and other industries.
Conclusion
Both the rubber coated filter cloth and the plate & frame filter cloth can be customized. If you want to learn more, you can pay attention to the ChinaFilter official website or contact us for consultation.
