Vulcanized filter cloth, also known as rubber-coated filter cloth or high-capacity filter press cloth, is produced by applying a vulcanization process to the base filter press cloth. A rubber layer (such as natural rubber) is vulcanized onto the surface of the filter cloth, forming a flexible sealing surface that effectively prevents slurry leakage and air leakage during filtration.
· Enhanced Sealing Performance: The vulcanization process significantly improves the sealing properties of the filter cloth. When used with a horizontal plate and frame filter press, it ensures a highly sealed filtration process, improving solid-liquid separation efficiency.
· Improved Blowback Efficiency: The vulcanized filter cloth enhances reverse airflow efficiency, reducing the moisture content of the filter cake to below 10%.
· Extended Service Life: The rubber layer mitigates wear and tear at contact points between the filter cloth and filter plate, extending the service life by over 60 days.
· Superior Durability: The filter cloth exhibits excellent tensile strength and crease resistance, ensuring structural stability under high-pressure conditions and minimizing compression loss.
· Mineral Dewatering: Used in solid-liquid separation for high-corrosive mineral slurries, such as copper and gold concentrates, and compatible with high-performance press filters for efficient dewatering.
· Chemical Filtration: Ideal for lithium ore processing and metallurgical slag treatment, offering excellent resistance to acid and alkali corrosion to support continuous equipment operation.
· Tailings Dry Drainage: Reduces filter cake moisture content to meet environmental discharge standards, minimizing waste disposal pressure.
Bolian strictly adheres to production processes and conducts meticulous inspections at every process, complying with ISO 9001 standards to ensure each batch of products and every filter cloth meets quality inspection requirements.
