It is very easy for titanium screws to be exposed in the air. It is very important to do a good job of preventing moisture and moisture.
Some titanium alloy screws need to deal with difficulties in wire and hardness in the production process, so it is necessary to select the appropriate hardness of the screw material, which is conducive to processing and production. However, in the production process, it is inevitable to encounter an environment that is not conducive to the preservation of titanium screws. Therefore, it is particularly important to use the component insulating impregnating paint to treat the screw. At present, the common insulating impregnating paints are: polyurethane impregnating paint and epoxy resin impregnating paint. Because the impregnating paint without volatile acid is selected, the selected vibration machine should ensure that the machine is solvent-free before use.
Because the heat resistance of the material is required for the working temperature. Therefore, when some titanium alloy screws are used for high temperature operation, the high temperature performance of the screw material needs to be considered. The use of melamine alkyd paint on titanium alloy screws requires strict control of the following conditions: a curing temperature slightly higher than 130 degrees Celsius and a curing time longer than 180 minutes, this operating condition must be strictly controlled. After implementing a series of painting execution procedures, the anti-corrosion performance of titanium screws is a strong guarantee. Especially in hot and humid seasons, because of the concept of rust, the conventional drying time of the sample paint factory is not necessarily abundant.
The mechanical properties of titanium screw and screw materials are good, and the requirements for strength are strong. Because some screws require a relatively high strength, then choose the higher strength of the screw material itself. The requirements for the corrosion resistance of the material under the working conditions, when part of the screw of the standard network is in contact with the product with strong corrosion, this requires us to consider the corrosion resistance of the strong helical steel wire. Use multiple methods to maintain the metal surface and prevent the surface corrosion of titanium alloy screws. The most important thing is to keep the metal titanium away from the corrosive environment and avoid its removal to inhibit the corrosion of titanium screws. By reducing the contact between the corrosive medium and the metal titanium surface, the target metal is achieved. self-stable state.
