Industry knowledge of vacuum filter belts

The surface of the belt is a row of horizontal grooves, in which there are one or more rows of drainage holes. The drainage hole section can use a pure rubber structure; The skeleton layer of the belt is made of high-strength polyester canvas or polyester canvas; The upper and lower covering glue of the filter belt can adopt different formulas according to the working conditions, meeting different needs such as acid and alkali resistance, heat resistance, oil resistance, and cold resistance; The molding and vulcanization of the tape adopt a one-time integrated composite process, ensuring the flatness of the tape body and stable performance.

Product classification:

Suitable for working environments that come into contact with acids and bases, such as phosphate fertilizers, alumina, catalysts (4A fluorite), and other industries. The covering rubber is made of rubber plastic blend material and filled with acid and alkali resistant inert medium, which has superior acid and alkali resistance compared to chloroprene rubber; The skeleton material is made of high-strength polyester canvas, which is more acid and alkaline resistant than cotton canvas; The drainage hole is made of pure glue, which effectively blocks the corrosion of acid and alkali liquids on the skeleton layer, and greatly improves the service life of the filter belt.

Mainly used for filtering high-temperature materials, 800C The covering adhesive is made of EPDM material with superior heat and aging resistance properties; The skeleton layer is made of high-strength polyester canvas, and heat-resistant glass cloth can be laid between the covering adhesive and the skeleton layer; The drainage hole section adopts a pure rubber structure, effectively blocking the influence of high temperature and filtrate on the skeleton material; The service life of the filter belt has been significantly improved.

Suitable for filtering environments of various oily materials. The covering adhesive is made of nitrile rubber with high acrylonitrile content, and the skeleton layer is made of high-strength polyester canvas. It has the advantages of body deformation, low rate of change, high strength, and wide range of use.

Suitable for working environments with temperatures ranging from -400C to+700C. The skeleton layer is made of polyester canvas, and the covering rubber is a combination of rubber and butadiene rubber, which has the characteristics of high elasticity, impact resistance, and cold resistance.
