Asphalt Plant Silt Filter Cloth , Woven Felt Fabric Heavy Duty 500GSM Waterproof

500GSM Aramid non woven filter cloth To asphalt metal cement steel

Aramid needle felt has good temperature resistance, flame retardancy and chemical properties, and can work continuously at 204 ° C: wear resistance, folding resistance, acid resistance, and can withstand repeated fluctuations of 250 ° C After baking at a temperature of 250 ° C for 24 hours, the heat shrinkage rate was only 0.9%. The limiting oxygen index (LOI) is 30. Only when the temperature reaches 400 °C, there will be signs of decomposition and carbonization. If it is impregnated with PTFE, it has a very high acidity and alkalinity, and most hydrocarbons will not The effect is that even if there is a small amount of fluoride, there will be no obvious corrosion. When the smoke in the gas contains large moisture or oil and hygroscopicity and deliquescence, and the dew point temperature is less than 70 °C, the aramid dust filter bag can be waterproofed and oil-repellent, and the PTFE film can be treated to prevent condensation or discharge. High concentration working environment.
