Key Specifications / Features

Aramid filter bag can withstand operating temperature of 200℃ under dry working conditions.
It is a hydrolyzable fiber which will be quickly hydrolyzed and damaged when exposed to high temperature, organic chemical and moisture content working condition.
Aramid filter bag can be applied to the operating temperature of 190℃ with service life reach 2 years at a 10% water concentration and weakly acidic and neutral environment.
If the water concentration is increased to 20%, the working temperature should be reduced to 165 °C if it has to be used for two years. The service life will be only half a year when working in 190℃ condition.

Aramid filter bag can’t be used in power plants that use sulfur-containing coal because it is particularly afraid of SOX erosion and water vapor.

Density 1.3g/cm3, breaking strength 4.9g/d, limiting oxygen index 29, is a kind fiber with non-thermoplastic, no self-igniting or combustion-supporting ability, it will only carbonize or decompose into small molecules at high temperature at 371 °C, they can only be singed but can’t be calendered when processing finish treatment.

FEATURES & BENEFITS

Excellent High-Temperature Performance – continuously working at 180℃ with max (instant) working temperature 220℃.

Good High-Temperature Stability and High Dimensional Stability – only 1% expansion rate at 230℃.

Fire Retardant Performance – this kind of filter bag won’t spontaneously combust and does not support combustion.

Good Chemical Corrosion Resistance.

Fast Production, High Labor Productivity and Low Product Cost

APPLICATIONS
