filter bag is a common filter material, widely used in industrial, medical, chemical and other fields. According to different materials, shapes, sizes and filtration accuracy, filter bags can be divided into a variety of different types. This article will introduce several common filter bag types and their characteristics.
1. Suspension filter bag
Suspension filter bags, also known as liquid filter bags, are a common filter material. Suspension filter bags are usually made of needled non-woven fabrics, mesh fabrics and other materials, and the filtration accuracy is usually between 0.5-200 microns. Suspension filter bag is suitable for the filtration of particles and microorganisms in liquid media, such as chemical media, food, medicine, beverages, etc.
Two, melt-blown filter bag
Melt-blown filter bag is a new type of filter bag, its production principle is through high temperature melting polypropylene and other materials into fibers, and then through electrostatic adsorption and compression molding. Melt-blown filter bag has excellent filtration accuracy, high temperature resistance, acid and alkali corrosion resistance and other characteristics, suitable for high temperature, high pressure, acid and alkali and other harsh environment filtration. At the same time, melt-blown filter bags can also be made into a variety of shapes and sizes, suitable for a variety of different filtration equipment.
Third, solid particle filter bag
The solid particle filter bag is mainly used for the filtration of solid particles and fine powders. Solid particle filter bags are usually made of nylon, polypropylene and other materials, and different filtration accuracy and size can be selected according to actual needs. Solid particle filter bags are widely used in building materials, chemical industry, powder metallurgy and other fields.
Four,
Air Filter bag
Air filter bags are usually made of needled non-woven fabric, filter paper, activated carbon and other materials. Air filter bag can effectively filter out dust, bacteria, viruses and other harmful substances in the air to ensure indoor air quality. Air filter bags are widely used in computer rooms and hospitals.
