NT high purity rosin, rosin special electronic welding, soldering rosin

Brand: NTCarton packaging

       Rosin is a pine tree within the high temperature melt into the oil out of the water-like, into a solid block after dry (no fixed melting point), its dark red brown color, mainly used in electronic circuits welding flux, mainly used in instruments in to rub the strings of musical instruments to play astringent effect.         As the metal surface in contact with air will produce a layer of oxide film, the higher the temperature, oxidation of the more powerful. This layer of oxide film on the metal to prevent the liquid solder wetting effect, as if stained glass of water can not wet the oil will make the same. Flux is used to remove the oxide film of a special material called flux.

Main functions:1. In addition to the oxide film. Essence of flux reduction reaction occurs in the material, thereby removing the oxide film, the reaction products into a suspension of the slag, floating on the solder surface.2. to prevent oxidation. Its melting, floating in the solder surface, forming isolation layer, thus preventing the oxidation of the weld surface.3. reduce the surface tension. Increase the mobility of solder, solder wetting help weldment.
