Treatment technology of Dacromet hexagon bolt Dacromet is a kind of inorganic conversion film containing zinc, aluminum and chromium, which is directly immersed in Dacromet treatment solution without electrodeposition, or adhered to the surface of workpiece by brush coating and electrostatic spraying, and then sintered. Dacromet hexagon bolt refers to the Dacromet plating on the [...]
Anti rust treatment method of Dacromet hexagon bolt: 1. Rust removal: The derusting process in Dacromet bolt treatment is different from the general pre-treatment method of coating, and acid pickling is used for derusting. This is because most of the parts treated by Dacromet are high-strength bolts, nuts and high-strength stamping parts, which will produce [...]
Application error of Dacromet hexagon bolt 1、 Substitute coarse for fine Some parts are connected with fine thread, but in the process of maintenance, the fine thread Dacromet hexagon bolt is lost or damaged, but there is no original matching, some people use coarse thread bolt instead, which is actually very undesirable. Replacing the fine [...]
Dacromet hexagon bolt has many advantages, which are listed as follows: Ultra strong corrosion resistance: the thickness of Dacromet hexagon bolt film is only 4-8 μ m, but its antirust effect is more than 7-10 times of that of traditional galvanizing, hot galvanizing or coating. The standard parts and pipe joints treated by Dacromet process [...]
