Products manufactured in rolled steel molding or storage during transport, the surface will rust. Because of the corrosion layer loose structure is not strong adhesion to the substrate, and can be composed of iron oxide and aluminum primary batteries, further promote aluminum corrosion, the coating will soon be destroyed Stone aluminum prices, it must be before painting In addition to the net. Product is commonly used pickling rust aluminum Stone, it does not make the four-way spot aluminum workpiece deformation aluminum factory, every corner can be cleaned of rust, rust fast supply aluminum four manufacturers, the cost is relatively low temperature, the time most of the acid is carried out at room temperature, when using heating pickling, general control between 40 ℃ ~ 70 ℃, although the temperature effect on the ability to improve the pickling larger, but the temperature is too high exacerbate the workpiece, equipment corrosion, impact on the work environment is very unfavorable; and completely remove rust under the premise of the pickling time should be as short as possible to reduce the impact of aluminum corrosion and hydrogen embrittlement. Therefore, the processing time processing aluminum price should be strictly controlled four-bath temperature and the workpiece, Al Stone, rolls supplied by Alcoa Aluminum Co., Ltd. Jinan rolls. Jinan Heshun Aluminum Co. (www.jnhsly.com) strong, credible, in Jinan, Shandong aluminum products industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead rolls in aluminum and you hand into the brilliant, for a better future!
