Chen Force chain of surface treatment methods are polished, black, galvanized, seepage nickel. Polishing known as tumbling into the roller chain is to use the chain itself in the role of friction, so as to achieve the purpose of rust, chain color polished as steel qualities. Blackening known black cook, the chemicals into the pool filled with water black lifting chain, heating, when the temperature reaches a certain extent, into a chain of polished and heating was continued after a certain time, will be in the chain formed on the surface layer of black oxide layer. This oxide layer stable chemical performance, storm drain in the air if not a chemical reaction, thus effectively protecting the chain body. At present most of the black market chain demand chain. White zinc plated and galvanized into color zinc plating, galvanizing process is mainly galvanized, galvanized chain looks beautiful, but in a wet environment, the surface prone to chemical reaction chain hoist lifting chain, a white alkaline substances . Infiltration of nickel on the surface of the chain is a chain of molecules penetrate into the nickel chain, chain beautiful surface infiltration of nickel, a bit like the color of stainless steel, and stable performance lifting chain sample under outdoor environment less prone to chemical reaction, and because infiltration of nickel all aspects of the environment without any pollution, it is a surface treatment currently China has strongly advocated, currently the industry is only chen do this surface treatment. Welcome to the needs of users inquiries. Chain packing. First, not be placed in an environment with corrosive acid gases, liquids, solids, and more can not be placed in close proximity to a variety of chemicals place. Second, can not be placed in a cool, wet environment, to avoid causing lifting chain damp and rust corrosion. Third, not placed in a oil, viscous liquids, and polluting the environment, prevent pollution lifting chain, causing corrosion. Fourth, before storage, the need to ensure a clean surface lifting chain and drying 100 lifting chain, and placed in a dry, airy, clean environment. In order to better preserve lifting chain, we need to always pay attention to changes its storage environment, the timely lifting chain storage environment improvement. _ Lifting chain hoists lifting chain Price (Online) _ lifting chain sling from Hebei chen Manufacturing Limited.
