Quality Control Of Enameled Wires II --Annealing Process Quality Control Of Enameled Wires II --Annealing Process

Due to the lattice stretching of the conductor during the drawing process, the conductor becomes hardened. After a certain temperature is heated, the softness required to restore the process after molecular lattice rearrangement is the purpose of the annealing. At the same time annealing process can remove the lubricant, oil on surface of the conductor during drawing. Make the conductor easy to paint, to ensure the quality of enameled wire. The most important thing is to ensure that the enameled wire has proper softness and elongation in the process of winding, and at the same time helps to improve the electrical conductivity.

Quality Control Of Enameled Wires I --Despooling ProcessQuality Control Of Enameled Wires I --Despooling Process

In normal operation of the enamelling machine, the operator's energy and physical strength are mostly consumed in the despooling part, the operator to pay a lot of labor in the exchange of despooling spools, and it is easily to cause quality and operational problems when proceed. The effective method is high-capacity despooling.

A Type of Flux for Welding Copper-Aluminum Pipe and Its Praparation MethodA Type of Flux for Welding Copper-Aluminum Pipe and Its Praparation Method

This invention relates to the field of flux technology, in particular, to a flux used for air - condition refrigeration, for welding environmental-friendly welding ring of energy-efficient copper-aluminum composite pipe and its preparation method thereof. Flux can be broadly devided into resin flux, water-soluble flux and inorganic flux. The resin flux is a flux in which an active agent is added to rosin and insoluble resin such as synthetic resin; The water-soluble flux is a flux that add active agent to resins dissolved in water such as Polyethylene glycol, Tween emulsifier; Inorganic fluxes made of inorganic acid such as hydrochloric acid and inorganic salts such as zinc chloride. The water-soluble and inorganic flux must be cleaned residue after soldering , because the residue of both at room temperature is also corrosive. Therefore, the welding flux of copper-aluminum wire mainly use resin flux, but its active ingredient and composition is different from the resin-core flux used for electronic packaging and solder wire. Therefore, studying a new type of flux used in the environmental welding of welded copper-aluminum wire has become one of the major urgent topics to be solved.
