Aluminum products Handling Precautions: closed water should be deionized water or distilled water, CNC lathes processing plants, no running water, Shenzhen CNC lathe machining, because ordinary tap water prone to scale adsorption in the hole, so that the transparency of the film is reduced. Ordinary tap water cl-, S042-, Cu2 + etc. have an adverse effect on the closing film hole. ① water quality. Ionic impurities in the water or impurities can seriously reduce the corrosion resistance after blocking oxide film, its appearance also have a certain degree of harm, CNC milling, so be sure to strictly control the quality of water and ensure its resistivity ≥5 × 105Ω? cm. The maximum allowable content of closed water impurity ions or impurities are as follows: harmful ions SO42- Cl- SiO32- PO43- F- NO3- allow content / 10-6 <250 <100 <10 <15 <5 <50 aluminum products remelting scrap value of aluminum has generally pedestrian attention because aluminum requires only 5% of its energy, and investment in equipment is minimal. According to the information reported now, 30% of the world's aluminum is aluminum waste recycling processing and production, and meet the quality requirements. If you use the right techniques, the number of recovered aluminum scrap depends on the market, processing, such as transportation of aluminum scrap recovery was 90%, the construction industry was 85%, aluminum beverage cans recovery was 80%, only the packaging industry lower scrap recovery.
