1) Plastic chemical packing materials mainly include polypropylene (PP), polyethylene (PE) and polyvinyl chloride (PVC). Polypropylene is generally used in China. Plastic fillers have good corrosion resistance and can withstand corrosion from general inorganic acids, alkalis and organic solvents. It has good temperature resistance and can be used below 100°C for a long time. Plastic packing are lightweight, cheap, have good toughness, impact resistance, not fragile, and can be made into thin-walled structures. It has large flux and low pressure, and is mostly used in absorption, desorption, extraction, dust removal and other devices. The disadvantage of plastic fillers is poor surface wetting properties, but their surface wetting properties can be improved through appropriate surface treatment. (2) Ceramic fillers Ceramic fillers have good corrosion resistance and heat resistance. Ceramic fillers are cheap and have good surface wetting properties. Their bigges...
