Introduction of pure nickel wire and nickel mesh
Pure nickel wire is mainly used to manufacture electron tube cathode, anode grid side rod, tube needle, etc. It has good mechanical properties and corrosion resistance to alkalis, such as sodium hydroxide. It also has better electrical, thermal and magnetic controllability characteristics. Applications include food and synthetic fibre processing, heat exchangers and the chemical and power industries. Typical manufacturing resistance thermometers, internal parts of the tube, such as grid side rods, struts and external parts of the tube, such as lead wires.
At room temperature, a dense oxide film is formed on the surface of the nickel wire in humid air, which can prevent the substrate metal from continuing to oxidize. The corrosion of nickel wire by hydrochloric acid, sulfuric acid and alkaline solution is very slow. Nickel wire dissolves slowly in dilute nitric acid. Strong nitric acid can passivate the surface of nickel wire and have corrosion resistance. Nickel wire is widely used in chemical chlor-alkali and other industries that require acid and alkali resistance. Existing production process of pure nickel wire: At present, the domestic production of pure nickel wire mainly adopts vacuum induction melting → ingot peeling → forging → grinding → rolling → drawing.
Widely used in the manufacture of ion-exchange membrane electrolyzer electrodes, with good corrosion resistance;
Metallurgical machinery is used for sieving and filtration under acid and alkali environment conditions; sieve filter in chemical and chemical fiber industry; pickling mesh in electroplating industry; battery collector mesh, etc.
Specifications wire diameter: 0.02mm-6mm
There are two types of nickel wire in China: N4 and N6.
The purity of n4 nickel wire is 99.8% and above,
The purity of nickel wire of n6 is more than 99.6%.
Nickel mesh: It is mainly used for sieving and separation of gas, liquid filtration and other media under acid and alkali environment conditions. The use of nickel mesh: nickel wire is woven into various specifications of mesh, cloth, with good acid resistance, alkali resistance, and other properties. It can be used as electrolytic hydrogen production, sintering and shielding of electronic components, and has very good effects. Mainly used in petroleum, chemical, chemical fiber, rubber wheel manufacturing, metallurgy, medicine, food and other industries.
Weaving of nickel mesh: plain weave twill weave. The specification of nickel mesh is 1-400 mesh.
Commonly used materials for nickel mesh: N4 N6 nickel content above 99.5
Characteristics of nickel mesh: Nickel has good mechanical strength and ductility. Intolerant of water, strong anti-corrosion ability to acids and alkalis,
Melting point: 1455 degrees, density: 8.902g/cm3 Nickel mesh has good plasticity and corrosion resistance.
