Chengdu-Branch of the aluminum passivation agent

First, the product features of this product is a new generation of green chromate-free pretreatment liquid Spray products can be formed on the aluminum surface layer of bright blue to pale yellow chemical conversion coating, the conversion film has a very excellent corrosion resistance, and after conversion coating and spray coating during the curing process of mutual penetration, provide excellent adhesion. It and China currently has chromate anti-rust agents, many manufacturers are using a completely different product. The product meets the requirements of the European Union, Japan, the United States and other developed countries, but also in line with environmental standards and import and export requirements of the world. Compared to conventional chromium agent has the following advantages: 1. Does not contain toxic hexavalent chromium compounds ions, hexavalent chromium ions to avoid harm to human health and the environment, non-toxic, non-polluting, non-flammable, non-explosive; 2. The wide operating range, the bath is easy to control, good stability. Second, the composition formulated with the groove ratio of 1: 5 to 1: 10, i.e., 1 part by passivation agent is diluted with 5 to 10 parts of deionized water. You must not use tap water, but can not use well water. Third, the technical parameters 1. Temperature 30 ~ 45 ℃ 2.PH value of 2.8 to 3.5 3. Time 1 ~ 3min four bath process control management 1. Determine the additional volume SYS-901 tests depending on the concentration of the bath; 2. to strictly control the production process bath PH value of 1.8 ~ 2.2, PH value is high, dilute nitric acid can be used to adjust; low PH value, can be adjusted diluted bath; 3. passivation slot does not produce, required closures cover Well, to prevent other impurities into and contamination. Fifth, the reference consumption consumption: 8-10 g / m2. VI, packaging and storage 25kg plastic drum sealed packaging, storage and transportation heat and sun.
