In the past, high temperature alkaline blackening process was used for steel blackening treatment for a long time, which has brought a lot of side effects such as high pollution and high energy consumption. Although many kinds of room temperature blackening products have been launched in the domestic and foreign markets, there are some problems. Beijing Zhubao Company has developed a new generation of metal blackening liquid solid black by using imported raw materials in accordance with the defects of existing technology and the development needs of production technology for blackening film, environmental protection, etc ®。 Solid Black ® It is metal blackening liquid at normal temperature, with unique formula, containing a variety of penetration, catalysis, corrosion inhibition, etc auxiliary It can complete the degreasing, rust removal and blackening process in one step without any shortage, representing the research and development direction and advancement of the market, and breaking the traditional blackening process.
Product features:
*Water based environmental protection product, non combustible.
*Solid Black ® It does not contain strong acid and chloride ion, and does not corrode metal.
*The blackening time is short, the color is uniform, stable and firm, and the corrosion resistance is strong.
*Solid Black ® Blackening liquid has good stability, simple operation, advanced and reliable technology.
*Energy saving, pure, low cost, suitable for various Metallic materials Blackening process.
*The blackening process can be carried out at normal and low temperatures without water washing, which can greatly increase the yield and reduce the cost.
*No discharge of three wastes, and no toxic substances such as selenium salt, bismuth salt, tungsten salt; No acid mist and harmful gas, no odor, no damage to appearance, friendly, safe and environmentally friendly operation and emission.
Scope of application:
Solid Black ® It is specially used for metal materials surface treatment The agent is applicable to the surface treatment process of alloy, carbon steel, cast iron, copper and other metals, and is widely used in machinery, power, chemical industry, automobile, * * * Instruments and Apparatuses Standard parts, professional parts Spring Equal blackening process; It can also be used for blackening process in special fields such as metal process products.
