Activated carbon adsorption box materials include: 1. Stainless steel: corrosion-resistant, high-temperature resistance, suitable for the treatment of corrosive gases containing waste gas and high-temperature waste gas. 2. Carbon Steel: after anti-corrosion treatment can be used for general waste gas treatment, but in the treatment of corrosive waste gas when the need for appropriate anti-corrosion measures. 3. Polypropylene: corrosion-resistant, suitable for processing some corrosive waste gas, but may not be suitable for high temperature. Four. Polyvinyl chloride: corrosion resistant, suitable for some corrosive exhaust gases, but may not be suitable for high temperatures. 5. Polytetrafluoroethylene: corrosion resistant, high temperature resistant, suitable for handling some special corrosive waste gas and high temperature waste gas.
