A filter mesh or filter screen is a screen used to filter solid particles, impurities or pollutants, usually made of metal or synthetic materials (such as stainless steel, nylon, polypropylene, etc.). The main function of a filter mesh is to filter out larger particles or pollutants in liquids, gases or solids by physical filtration, thereby improving the purity of the fluid or ensuring the normal operation of process equipment.
Filter meshes have different pore sizes and materials, which can meet different filtering precision and application requirements, and are widely used in water treatment, oil and gas separation, chemical industry, food processing, pharmaceutical manufacturing and other industries.
Main Features
Diverse materials:
Stainless steel filter mesh: Due to its high temperature resistance, corrosion resistance and oxidation resistance, it is widely used in chemical, petroleum, food and other fields.
Synthetic materials such as nylon, polyester, polypropylene: Suitable for lighter occasions with low corrosion resistance requirements, commonly used in water treatment, air filtration, etc.
Metal materials such as copper and aluminum alloys: Commonly used in specific chemical and industrial applications, with strong mechanical strength and good thermal conductivity.
Fine aperture design: The aperture of the filter mesh can be divided into various specifications according to needs, ranging from a few microns to a few millimeters, which can effectively select the appropriate filtration accuracy according to the size of the particles in the fluid.
High strength and durability: The filter mesh has high strength and durability, and can withstand certain pressure, mechanical vibration, stretching and corrosion, so it can work stably for a long time.
Anti-clogging: The design of the filter mesh usually has good anti-clogging, especially the metal mesh, whose gap structure can prevent most particles from clogging and adapt to long-term filtration.
Washability: Many filter meshes (especially metal meshes) can be washed and reused, which is particularly suitable for high-precision filtration and industrial occasions that need to be repeatedly used.
Application
Liquid and gas filtration: Filter meshes are widely used for preliminary or fine filtration of liquids and gases. For example, in industrial water treatment processes, they can be used to remove suspended matter, impurities and particles in water; in air purification systems, they are used to capture dust, pollen, etc.
Oil and gas industry:
In the separation process of oil and gas, filter mesh is often used to remove solid impurities in oil-water separation and gas-liquid separation, protecting pipeline systems and equipment from damage.
Food and beverage industry:
In the process of food processing, filter mesh is used to separate impurities in raw materials to ensure the quality of products. For example, in the refining process of edible oil, it is used to remove impurities, pigments and other particles in oil.
Chemical industry:
In the reactor and solution filtration processes in chemical production, filter mesh is used to separate solid particles to ensure the smooth progress of the reaction.
Pharmaceutical industry:
In the pharmaceutical process, filter mesh is used to separate and purify drug ingredients to ensure the purity and quality of drugs.
Cooling system and heat exchange equipment:
In industrial cooling towers and heat exchange equipment, filter mesh is often used to separate impurities and microorganisms in water to ensure the efficient operation of equipment.
Agriculture and horticulture:
Used for water irrigation filtration, removing sand, dirt or impurities in water sources, and ensuring the smooth flow of irrigation systems.
