To understand the components of the string wound filter element, we must first know its main composition, know the composition principle, in order to analyze the characteristics of its components in detail. Wire-wound filter element is a kind of deep filter element which is made by adding textile fiber yarn and winding on porous skeleton. Then, its component characteristics are mainly the characteristics of winding yarn materials and skeleton materials, which are the main components.
The yarn material of the yarn depth filter element usually includes three materials, which are absorbent cotton fiber, polypropylene fiber and acrylic fiber. The advantage of these materials is that they have very good filtration characteristics and performance, and the chemical stability is very high, which can meet the filtration requirements under various working conditions, ensure the filtration effect and improve the filtration efficiency.
The common material of the yarn filter element core skeleton is mainly divided into two kinds, respectively, polypropylene skeleton and stainless steel skeleton, polypropylene skeleton is mainly concentrated in the application scenario of liquid filtration at normal temperature, while the wire-wound filter cartridge core of the stainless steel skeleton will be stronger and more durable in the structure, suitable for high temperature and high pressure or highly corrosive liquid filtration application scenario.
