Moisture-proof Method Of Hexagon Socket Head Bolt

　1. Use component insulation impregnating varnishes, such as epoxy resin or polyurethane impregnating varnish. No volatile acid was found in the selected coating. Solvent-free paint is used for vibrating machinery.

　　2. When using melamine alkyd paint, properly adjusts the fixed-line temperature and fixed-line time, the fixed-line temperature is slightly higher than 130 degrees, and the fixed-line time is greater than 180 minutes. It is necessary to strictly implement the process. Especially in the hot and humid season, from the perspective of rust, the regular drying time of the paint factory is not necessarily. They all have a specific internal shape.

　　3. The surface corrosion treatment of hexagon socket head bolt refers to the metal appearance of the maintenance layer applied by various methods. Its function is to isolate the metal from the corrosive environment to inhibit the corrosion process or reduce the contact between the corrosive medium and the metal surface, to achieve the purpose of preventing or slowing down corrosion.
