Sintered stainless steel fiber felt

Sintered stainless steel fiber felt is a filtration medium made from extremely fine stainless steel fibers, which are micron-sized in diameter. The manufacturing process involves non-woven fabrication, lamination, and high-temperature sintering. This results in a finished felt with a gradient of different pore size layers, allowing for precise control of filtration accuracy and enhanced pollution absorption. The three-dimensional network structure, porous nature, high porosity, large surface area, and uniform pore size distribution of the sintered fiber felt enable continuous filtration performance.

The sintered stainless steel fiber felt overcomes the drawbacks of metal mesh clogging and the fragility of powder filter products. It compensates for the limitations of fragile structures and low flow rates, which are common in filter paper and filter cloth materials. Moreover, it exhibits excellent heat resistance, compression resistance, corrosion resistance, and high filtration precision, making it an ideal choice for demanding applications.

Application

Stainless steel fiber felt is widely used in the filtration industry for both surface filtration and depth filtration applications.

1. Surface Filtration: Stainless steel fiber felt is used for screening and capturing particles in surface filtration. It can be employed to remove suspended solids and solid particles from liquids, as well as tiny particles and contaminants from gases. In surface filtration, the fine fiber structure of stainless steel fiber felt effectively prevents particles from passing through, ensuring high filtration efficiency. This makes it widely applicable in industries such as liquid processing, water treatment, food and beverage processing, and more.

For example, in the water treatment industry, stainless steel fiber felt is used as the filter medium in cartridge filters or filter bags. It effectively removes sediment, rust, and other impurities from the water, providing clean and purified water for various applications.

2. Depth Filtration: Stainless steel fiber felt is also suitable for depth filtration, where it captures smaller particles and microorganisms. In-depth filtration, the fiber structure of stainless steel fiber felt forms a dense network that filters tiny particles through mechanisms like electrostatic adsorption, entrapment, and capture. This makes it useful in industries such as medical, pharmaceutical, electronics, and microelectronics for high-purity gas and liquid filtration, ensuring product quality and a clean production environment.

For instance, in the pharmaceutical industry, stainless steel fiber felt can be used in sterile filtration processes to remove bacteria and particulate contaminants from pharmaceutical liquids. It provides an effective barrier that ensures the purity and safety of the final pharmaceutical products.
