Currently, industrial pollution in our country is the largest source of PM2.5. Among them, cement manufacturing, coal-fired power stations, and iron and steel metallurgy are the three major killers of industrial pollution sources. Therefore, to control PM2.5, industrial dust removal cannot be ignored, and here is It is necessary to use three-layer five-layer high-efficiency filter paper.
Polyphenylene sulfide fiber has good properties of high temperature resistance and acid and alkali corrosion resistance, and is suitable for dust removal from coal-fired flue gas, but its ability to resist oxidation is poor: although polyimide can make up for its shortcomings, it The hydrolytic stability is not ideal. As the “King of Plastics”, polytetrafluoroethylene fiber has excellent chemical resistance, but is more expensive.
Currently, there are two lamination methods for three-layer and five-layer high-efficiency filter paper: glue lamination and thermal lamination. 1. Glue lamination is a relatively elementary lamination method, which has low composite strength, is easy to peel off, and has a short service life. Due to the penetration of glue, it has poor air permeability and is not suitable for dust cleaning, which weakens the superior performance of PTFE. 2. Thermal lamination is an advanced lamination method that completely maintains the superior performance of PTFE film, but has strict requirements for thermal lamination technology.
