What kind of spark will there be between the Raschig ring and graphite? 

This is the key product we are going to introduce today, Graphite Raschig Ring. 

It is the perfect combination of Raschig ring and graphite. Raschig ring is the first artificial filler used in the industry. It is usually made of ceramic or metal plate, we named it ceramic Raschig ring and metal Raschig ring. Its height is equal to the diameter. 

The commonly used size of the graphite Raschig ring is 25mm ~ 75mm (also as small as 6mm and as large as 150mm). 

Ceramic wall thickness is 2.5mm ~ 9.5mm, metal ring is 0.8mm ~ 1.6mm. When strength is allowed, the wall of the ring should be as thin as possible. Although the mass transfer performance of the Raschig ring is not ideal, it is still used in some factories because of its simple structure, easy manufacture and low cost. Rhenium graphite is the name of a mineral that is usually produced in metamorphic rocks. Coal or carbonaceous rocks (or sediments) are formed by regional metamorphism or magma intrusion, and graphite is an allotrope of elemental carbon. Each carbon atom is connected in a hexagonal arrangement to three other carbon atoms. The device is a honeycomb structure with multiple van der Waals gravity. Since each carbon atom emits electrons, these electrons can move freely, so graphite is an electrical conductor. Graphite is one of the softest minerals. It is opaque and greasy, and it ranges from iron black to steel gray. The shape is crystalline, flaky, scaly, striped, flaky or scattered in metamorphic rocks. Chemically inactive and inert, resistant to corrosion.

Graphite Raschig ring is a commonly used packing in packed towers. It has the advantages of small specific gravity, high structural strength, strong corrosion resistance and high separation efficiency. It can replace non-metal Raschig rings such as ceramics and metals. Its advancing with the times and innovation has won the consensus of the market. Because the graphite lacquer ring is not particularly common, I will give you a detailed introduction to the knowledge of graphite lacquer ring. 

Graphite Rashig ring has the following characteristics: This product is made of graphite powder, phenolic resin and special additives. It has good toughness, high temperature resistance, corrosion resistance to non-strongly oxidizing acidic media such as hydrochloric acid and sulfuric acid, and some organic solvents. It's commonly used specifications are: 19/20mm, 25mm, 37/38mm, Raschig ring 50mm and so on.
