High Temperature Filter Material Aramid Becomes a Bestseller

As an indispensable accessory in the cloth bag filter, the dust collecting filter bag is the core component of the cloth bag filter unit. It is a kind of dust removal product that the production enterprise studies with great concentration. Its price is also highly concerned by users. Among normal temperature, medium temperature and high temperature filter bags, this year high temperature Metas (Aramid) filter bag has become the biggest selling point.

Metas (Aramid) dust collecting filter bag has high temperature resistance and long working life. It is the first choice of filter material for bag dust collector in high temperature filtration occasions. High temperature resistant Metas (Aramid) filter bag has the characteristics of high temperature resistance, high strength, resistance to acid and alkali corrosion, abrasion resistance, folding resistance, etc. Through different surface chemical treatment and post-cleaning process, it also has easy cleaning, water and oil resistance, anti-static and other functions, and can even suitable for 200 °C-300 °C temperature.

The main selling points of high temperature resistant Metas (Aramid) filter bags are:

1. Excellent temperature resistance: it can be operated continuously at a temperature of 204C℃(instant temp. 250℃), and it can accept repeated fluctuations in temperature at 250℃;

2. Dimensional stability: only has a thermal shrinkage of less than 1% at a temperature of 250℃, which has excellent high-temperature stability;

3. Chemical resistance: low concentration of acid and alkali and most hydrocarbons will not affect it, even a small amount of fluoride will not significantly corrode it;

4. Fire resistance: differentiation and carbonization only begin at 400℃, and the limit oxygen index (LOI) is 30, which does not spontaneously ignite or assist combustion.

Compared with the high temperature resistant filter material of synthetic fiber, the Aramid filter bag overcomes the shortcomings of chemical fiber filter material such as large elongation and deformation, low temperature resistance and poor corrosion resistance. Its size is stable, the strength is very good, and the price is lower than other high temperature resistant chemical fibers. Therefore, Aramid filter bags are widely used in non-ferrous metal smelting, chemical industry, carbon black, building materials, power generating and other industries.
