Detailed Product Description: | (1) precision machining parts pretreatment process issues that need attention: finely machined parts, although the natural oxide film surface was beginning to generate, easier to clear, but the greasy heavy, especially in the hole and around (because the machining process lubrication needs to add), this type of workpiece must be cleaned by an organic solvent, if not only the direct use of caustic heavy greasy addition to the net hard and fine machining surface can not afford a long period of alkali corrosion, the result will affect the workpiece surface with roughness and tolerances, may eventually become waste. (2) casting parts pretreatment process issues that need attention. Casting parts, not all surfaces are machined, machined surfaces without leaving too thick oxide layer formed during casting, and some there are the sand, and you should be machined or sand blasting method to remove The original site of the oxide film, or by caustic after processing, the only way to both the oxide layer in addition to the original unprocessed parts of the net and avoid changing the machining tolerances of the parts. subject to prior organic solvent cleaning according to process requirements, the workpiece into the heat treatment or welding processes: http://www.jndcly.com/ aluminum manufacturer (3) issue through heat treatment or welding process workpiece pretreatment processes that need attention , in addition to the net surface oil, but in general this is not possible, so the surface to form a layer of oil coking sintered material, this layer of char in an organic solvent is in addition to the net hard, if soaked in lye will cause local corrosion, pitting, or cause uneven, seriously affecting the quality of products. With concentrated nitric acid immersion approach to this layer of soft foam char, char to be a little soft after washing thoroughly in lye that in addition to the net. http://www.jndcly.com/ aluminum manufacturers aluminum coil manufacturer |
