In the production of filters, the role of the filter is very important. It supports the filter element and protects the filter paper and non-woven fabric inside. And there are many types of filters, do you know how many filters there are?
Next, I will share with you 5 commonly used metal filters.
1. Expanded metal mesh
The steel mesh used for the filter is flattened, its thickness is between 0.4-0.8mm, and the material is generally galvanized sheet, which is often used in the filter.
2. Perforated mesh
The round hole punching filter is punched into holes by hand or machine. It is used as a filter cartridge outside the filter for support and protection. Coiled sheets are generally used, and galvanized sheets and stainless steel sheets are more commonly used.
3. Woven mesh
Woven mesh is a wire mesh made of stainless steel wire, galvanized wire, copper wire, steel wire and other metal wires woven by warp and weft on a loom. Mainly used for gas, liquid filtration and other media separation.
4. Welded mesh
Fine welded mesh is welded by high-quality low-carbon steel wire and stainless steel wire, and some mesh surfaces will be powder-coated.
The process of welded wire mesh is divided into welding first and then plating, first plating and then welding; it is also divided into hot-dip galvanized welded wire mesh, electro-galvanized welded wire mesh, dip-coated welded wire mesh, stainless steel welded wire mesh, etc. Also used in the production of filters.
5.Knitted wire mesh
Knitted mesh air-liquid filter, also known as bubble-breaking mesh, filter mesh, knitted mesh, is actually a silk mesh improved by the traditional sweater weaving method. Two types of knitted wire mesh: plain and corrugated.
The specific application of the filter:
1. The filter screen can be used to make the filter pad of the wire mesh demister.
2. Filter screens for gas-liquid separation, gas-water separation, oil-water separation and other devices, exhaust gas purification.
3. Various filters on engines such as automobiles and tractors.
Each filter product produced by Dongjie Factory has its different specifications and characteristics. If you want to know more about filters or have other ideas, welcome to communicate with us.
