Advantages of glass fiber filter cartridge

Time : 2023-06-27 Hits : 1

The glass fiber filter element is usually referred to as the glass fiber filter element, which belongs to a deep filter element and is made by winding. It is widely used in filtration of oil, water, air, etc. The common sizes are 10 ", 20", 30 ", 40", etc. In addition, if it is made of polypropylene skeleton, the working pressure can reach 0.6Mpa; If the stainless steel framework is used, the working pressure can reach 0.8Mpa. In terms of temperature resistance, the main feature of this filter element is that if it is a degreased cotton fiber filter material, the working temperature can reach 120 ℃, while the other filter materials can reach 90 ℃. So, what are the disadvantages of glass fiber filter element?

At present, the commonly used glass fibers produced on the domestic market are divided into alkali free and medium alkali. Alkali free E-glass fibers are highly stable to water, wet air and weak alkali solutions at room temperature, but are not resistant to acid and alkali attack of higher solutions. The medium alkali fiber has good water resistance and acid resistance. Therefore, it is necessary to select glass fibers with different components as filter materials according to the properties introduced. In addition, although the glass fiber filter element has smooth surface and small filtering resistance, it is conducive to dust stripping. However, the filter element is brittle, non folding, non abrasion resistant, and deformed after being pulled. However, the glass fiber fabric without surface chemical modification can not meet the requirements of high temperature filter materials, so its properties largely depend on the surface treatment process, formula and fabric structure.

In addition, we also need to know that the fiberglass filter element has been widely used in hydraulic oil filtration, high-temperature gas filtration, and corrosive solution filtration, and has achieved good filtration results. This product has the advantages of high precision, corrosion resistance, stable filtering performance, etc., but it is easy to deform, so it is not suitable for the same working conditions under high-pressure environment. Its filtration performance is relatively stable under normal pressure.
