Solving methods: ① not use bad beat slag refining agent containing sodium or magnesium salt, preferably using NaF component refining modificators, or N2 gas refining; ② not use release agents containing plant fiber and plant fiber-containing machine Shandong casting aluminum cutting fluid, is best replaced by oil-based rust-proof cutting fluid; ③ the product can not be long-term exposure to the sun, or likely to cause the accumulation of fly ash surface textile products; ④ light board placed on certain product packaging cartons Stretch 6 bread wrapped use, if the product wet casting aluminum, must be timely ventilated place to dry. You can use hot water for cleaning aluminum volume. hot water remaining on the surface of the substrate mainly degreasing detergent clean, and ensure that these residues can dissolve prevent degreasing agent on board cause secondary pollution. use way more for dipping and spraying brushing way. The best water quality hardness with not too high, otherwise the minerals in the water will be generated on the substrate surface ore spot. Second, the hot alkaline degreasing faster line speed due to the pre-coated line Jinan casting aluminum manufacturers, so the use of degreasing agents are typically higher concentrations typical degreasing agent containing sodium hydroxide (NaOH), carbonate Sodium (Na2Co3), water glass (Na2SiO3), phosphate and other components of a hot alkaline degreasing step is generally a two-step process to ensure that the aluminum coil substrate surface clean, and multi-purpose spray brushed aluminum casting factory in Jinan manner |. cis Aluminum | Aluminum Casting Aluminum Co., Ltd. provided by Jinan Heshun.
