What are the classifications of filters?

2020-12-09
Filter mesh is abbreviated as filter mesh, which is processed by metal wire meshes of different meshes. Its function is to filter molten material flow and increase material flow resistance, thereby filtering out mechanical impurities and improving the effect of mixing or plasticizing. It has acid resistance, alkali resistance, temperature resistance, abrasion resistance, etc.; it is mainly used in mining, petroleum, chemical, food, medicine, machinery manufacturing and other industries. The filter is divided into textile fiber filter and metal filter. The machine installed with the filter is called a filter, which is used to filter natural water and food. 1. Used for screening and filtering under acid and alkali environmental conditions, as a mud mesh in the petroleum industry, as a screen filter in the chemical and chemical fiber industry, and as a pickling mesh in the electroplating industry...

2. Used in mining, petroleum, chemical, food, medicine, machinery manufacturing and other industries.

3. Used in air conditioners, purifiers, range hoods, air filters, dehumidifiers, and dust collectors, etc., suitable for various filtration, dust removal and separation requirements

The metal filter screen generally uses stainless steel wire, nickel wire, and brass wire as materials. Metal wire woven dense weave nets are arranged densely in the mid-weft. There are five methods: plain weave, twill weave, plain Dutch weave, twill Dutch weave, and reverse Dutch weave. Nickel tape has ferromagnetic metallic elements, which can be highly polished and resistant to corrosion. Mainly used in alloys (such as nickel steel and nickel silver) and as a catalyst (such as Raney nickel, especially as a hydrogenation catalyst). It is the preferred raw material for manufacturing filters.
