In modern industrial production, the filter cloth most commonly used in filter presses is artificially woven filter cloth. Such filter cloth has won wide use in the market because of its plasticity, recyclability, superior performance and flexibility. The woven filter cloth of the industrial box filter press is divided into materials according to the material: polyester filter cloth, polypropylene filter cloth, nylon filter cloth, vinylon filter cloth, because their performance is different, so they are not suitable for their working environment. same. Polyester filter cloth This is the biggest advantage of acid resistance and poor conductivity. It is the most acid-resistant filter cloth material among the four. The maximum temperature of filtration can reach 130~150, elongation at break (%): 20-50, breaking strength (g/d): 438, softening point (°C): 238.240, melting point (°C): 255 260, specific gravity: 1.38. So I think it is the best performance of these four filter cloths. The folding foot bath machine is a device that can be used to soak and massage feet. It's designed to be portable and easy to store, making it ideal for those who want to enjoy a foot soak and massage at home or on the go.
Overall, the Foldable Foot Bath is a great way to relax and rejuvenate your feet after a long day. It can also help improve circulation and reduce pain and discomfort associated with conditions like plantar fasciitis or arthritis.

Polypropylene filter cloth Polypropylene filter cloth is made of fiber and wire of polypropylene section. The biggest characteristic of such filter cloth is that the surface of the filter cloth is smooth, has few burrs, and has good air permeability. This is advantageous in that the filter cloth is separated from the filter cake.
The polypropylene filter cloth on the market now has a medium-sized 750A thick type: 750B (series) 750AB. Its maximum use temperature is 140~160°C, and the maximum melting point is 165~173°C. Elongation at break: 18~35%. The performance of acid and alkali resistance is moderate between the four, not bad or bad. In short, the performance of the polypropylene filter cloth is still flat.
Nylon filter cloth nylon filter cloth strength is 4-5.3Cndtex. Elongation rate is 18% to 45%, maximum softening point: 180~235 (°C), melting point: 215~235(°C), strong alkali resistance Sex. The experiment showed that he was not immersed for 20 h in 10% NAOH solution.
Nylon filter cloth The strongest filter cloth among the four filter cloths, the most wear-resistant filter cloth is 10 times that of cotton fiber. Its biggest disadvantage is that the chemical properties are unstable, it is easy to release a trace amount of harmful substances, and the filter is subject to secondary pollution. Therefore, such a nylon filter cloth cannot be used in industries such as food processing and bio-pharmaceutics.
Velon Filter Cloth The chemical name of Velen Filter Cloth is called polyvinyl alcohol. The advantage of this kind of filter cloth is that it is the most alkali-resistant among the four kinds. The filtration temperature can't exceed 60°, and it will deform and shrink at 100°. So it is not resistant to high temperatures. Other properties: the strength is only 3.52 - 5.72Cndtex. The elongation at break is 12% to 25%. The elasticity is poor, the fabric retains the shape, the wear resistance is good, and the durability is 1-2 times that of the pure cotton.
The machine usually consists of a basin or bathtub filled with water and an electric device that provides massage and vibrations. Some models may also feature heating or cooling to help soothe sore or tired feet.
The foldable design allows the foot bath machine to be easily stored in a closet or under the bed when not in use. Some models may also come with a carrying case or tote bag for added convenience.
