In the process of industrial production, a lot of dust and harmful gases will be produced, and the inhalation of these substances into the human body will cause harm to the human body. Therefore, it is particularly important to have a material that can filter dust.
PTFE dust removal membrane is one of the materials that solves these problems.
PTFE dust removal membrane has a node-fine fiber structure, forming hundreds of millions of micropores per unit area, which can effectively intercept dust in the air. It is very suitable for air purification fields, such as vacuum cleaner applications. The membrane’s high breathability and The high interception efficiency enables the vacuum cleaner to not only effectively intercept dust particles, with the highest accuracy reaching level H14 (99.995%), but also allows the vacuum cleaner to maintain low energy consumption, and the material can be washed to restore performance and be reused.
Industrial dust removal applications include interception and collection of polluted dust in thermal power plants, steel plants, cement plants, waste incineration plants and other fields. Due to the non-viscosity and surface filtration characteristics of the PTFE membrane, the filter cake layer formed on the surface passes through backflush It is easy to peel off and remove, thereby restoring the breathability performance and greatly extending the service life of the filter bag or filter cartridge.
Due to its excellent corrosion resistance, excellent thermal stability and good mechanical properties, the use of PTFE filter materials in the field of industrial smoke and dust purification has increased rapidly. Research data shows that from 2016 to 2020, waste incineration, coal The compound annual growth rate of the demand for PTFE filter materials in electricity, steel and cement dust removal systems all exceeds 10%, and some industries even exceed 20% (such as waste incineration).
The main feature of PTFE dust removal membrane is surface filtration, which can improve filtration efficiency and improve the problems of increasing filtration pressure and high concentration of fine dust emissions that often occur in traditional filtration methods.
It has strong hydrophobicity, low surface energy, and good non-adhesion. It can easily remove dust accumulated on the surface of the material, so it can be rinsed with water to restore its performance, achieve repeated use, and extend its service life.
Compared with other high-efficiency filter materials.
