What are the differences between ceramic, metal , and plastic packing

Chemical packing products have been widely used in oil refining, metallurgy, gas, oxygen generator and other industries. At present, the most popular fillers on the market mainly include plastic fillers, ceramic fillers, and metal fillers. Each kind of filler has its own advantages, and there are differences in the use effect, so people must pay attention to understand the difference between them when purchasing, and choose the correct chemical packing.

1) Ceramic tower packing have good corrosion resistance and heat resistance. Ceramic fillers are cheap and have good surface wetting properties. Brittleness and brittleness are their disadvantages. It is widely used in gas absorption, gas scrubbing, liquid extraction and other processes

2) Metal packing, metal chemical fillings can be made of various materials, metal filler can be made into thin-walled structure, large flux, low gas resistance, and high impact resistance, can be used under high temperature, high pressure, high impact strength Use, the corrosion problem is mainly considered in the application. For non-corrosive or low-corrosive systems, carbon steel packing should be preferred, and its cost is low. And has good surface wetting properties. Stainless steel packing has strong corrosion resistance, but its cost is high.

3) The plastic packing has good corrosion resistance and can resist the corrosion of general inorganic acids, alkalis and organic solvents. It has good temperature resistance and can be used for a long time below 100°C. Plastic fillers are light, cheap, have good toughness, are impact-resistant, not brittle, 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 that the surface wetting performance is poor, but its surface wetting performance can be improved by appropriate surface treatment.
