Asphalt mixing plant specific dust bag

Our company produces high temperature dust bag imported fiber as raw material, using the international advanced standard, formed by the introduction of advanced equipment manufacturing;

The filter has the following four features:

① excellent temperature resistance: at 204℃ continuous operation at temperatures (instantaneous temperature 250 ℃ and can withstand over 250 ℃ of momentary fluctuations in temperature.

② outstanding dimensional stability: only 250 ℃ temperature heat shrinkage rate of less than 1%, and has excellent high temperature stability.

③ excellent fire resistance: 400 ℃ will decompose and carbonation, limiting oxygen index (LOI) is 30, not spontaneous combustion or combustion.

④ excellent chemical resistance: low concentration of acids and bases, and it makes no difference to most hydrocarbons, even small amounts of fluoride are not obvious to corrosion is one of the ideals of asphalt concrete mixing plant fittings.
