Brass And Copper Gas-liquid Filter Screen

July 29, 2023

Gas-liquid filter screen, abbreviated as gas-liquid screen, also known as foam capture screen or woven screen, is a special form of woven wire mesh. It is the main component used in the production of wire mesh demisters, oil gas separators, dust removal, environmental protection, engine noise reduction, mechanical shock absorption, and other engineering projects, and is also widely used in the automotive and electronic industries. The purpose of copper gas-liquid filter mesh and red copper gas-liquid filter mesh is to be made into a corrosion-resistant wire mesh defoamer and a corrosion-resistant filter pad. High conductivity copper wire gas-liquid filter screen is made into a shielding device for electronic and electrical products to prevent electromagnetic interference. Brass gas-liquid filter screens and copper gas-liquid filter screens can also be made into rust and dirt removal materials in the shipbuilding and machinery manufacturing industries


Copper has good physical and chemical properties such as conductivity, thermal conductivity, corrosion resistance, and ductility. Conductivity and thermal conductivity are second only to silver, and pure copper can be pulled into very fine copper wires to make very thin copper foil. The fresh section of pure copper is rose red, but after the Copper(II) oxide film is formed on the surface, the appearance is purple red, so it is often called red copper. The material of the copper wire gas-liquid filter screen is composed of copper, which is a simple copper substance.


It is named after the purple copper due to its purple red color. Red copper is industrial pure copper, with a melting point of 1083 ℃, no isomeric transformation, and a relative density of 8.9, which is five times that of magnesium. It is about 15% heavier than ordinary steel. It has a rose red color and a purple color after forming a film on the surface, so it is generally called purple copper. It is copper containing a certain amount of oxygen, hence it is also known as copper containing oxygen.


Red copper is a relatively pure type of copper, which can generally be approximated as pure copper. It has good conductivity and plasticity, but its strength and hardness are relatively poor. Red copper has excellent thermal conductivity, ductility, and corrosion resistance. The trace impurities in red copper have a serious impact on the conductivity and thermal conductivity of copper. Titanium, phosphorus, iron, silicon, etc. significantly reduce conductivity, while cadmium, zinc, etc. have little effect. The solid solubility of oxygen, sulfur, selenium, tellurium, etc. in copper is very low, and they can form brittle compounds with copper, which has little effect on conductivity but can reduce processing plasticity. Red copper has good corrosion resistance in the atmosphere, seawater, certain non oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solutions, and various organic acids (acetic acid, citric acid), and is used in the chemical industry. In addition, red copper has good weldability and can be processed into various semi-finished and finished products through cold and thermoplastic processing. In the 1970s, the production of red copper exceeded the total production of other types of copper alloys. Therefore, the gas-liquid filter screen made of red copper, called the red copper gas-liquid filter screen, is widely used in the chemical industry
