What is the difference between monofilament filter cloth and double layer monofilament filter cloth

Double-layer monofilament filter cloth refers to a filter cloth woven from double-layer monofilament, such as polypropylene double-layer monofilament, polyester double-layer monofilament, etc. Belt filters are widely used.

The monofilament filter cloth is woven from a single wire, and has the characteristics of easy cake unloading, easy regeneration, and high filtration efficiency.

The monofilament filter cloth has high stability, and it is not easy to stretch, shrink and discount when running on the machine. With the addition of post-processing technology such as high temperature setting and calendering, the surface of the monofilament filter cloth is smoother and less prone to accumulation of filter residues. In addition to the characteristics of monofilament material, the double-layer monofilament filter cloth is woven from monofilament at the top and bottom, so it has support and good material filtering effect and is not easy to block.

Definition of mesh: line/square inch.

1. High mesh number and low opening area, reducing flow rate and increasing filtration fineness, suitable for low-viscosity and high-precision products.

2. Low mesh number and high opening area, increase flow rate and reduce filtration fineness, suitable for products with high viscosity and low precision.

3. The monofilament filter cloth has a relatively high porosity, is not easy to block the net, has high strength, is relatively durable, and is easy to clean.

4. Compared with monofilament, multi-filament filter cloth has lower porosity, higher elasticity, higher filtration accuracy, easy to block the net, difficult to clean, and higher loss, suitable for pressure filtration.

5. Various materials are suitable for different industries and various special needs, and there is no certain standard.

Common polypropylene and polyester double-layer monofilament materials are commonly used in metallurgy, chemical industry, environmental protection, non-ferrous metals and other fields, and are widely used in these fields.

Monofilament is warp/weft, all are one thread, monofilament filter cloth is not easy to block, good regeneration effect, long service life, convenient unloading, used in vacuum belt filter, drum machine, centrifuge and other filtering machinery The more, the better the effect. Multifilament is warp/weft, which is woven from multiple fibers into a single silk. According to the length of the fiber, it is divided into long fiber multifilament / short fiber multifilament. The multifilament filter cloth has a better retention effect on fine particles. After the particles enter the filter cloth, it is difficult to clean out due to the large number of fibers. Therefore, compared with the monofilament filter cloth, the regeneration effect of the multifilament filter cloth is not good, and it is easy to block and inconvenient to discharge. (It is better to unload the imported fabrics treated by Yaguang). However, in many chemical industries, due to the small particles of the material to be filtered, the monofilament filter cloth cannot be satisfied, so the multifilament cloth is still widely used.
