Titanium alloy screw, titanium screw moisture-proof and moisture-proof method
Titanium alloy screws exposed in the air will be easy to rust, so titanium alloy screws need to do moisture-proof and moisture-proof work:
1, the choice of component insulation dipping paint, such as epoxy resin or polyurethane dipping paint. Choose coatings that do not contain volatile acids. Use solvent-free paint for vibrating machinery.
2, titanium alloy screws on the use of melamine alkyd paint, should adjust the curing temperature and curing time and curing temperature slightly higher than 130 degrees Celsius and curing time is more than 180 minutes is appropriate, need to strictly implement process, especially in hot and humid season, because the rusty rust point of view, the concept of conventional drying time sample paint factory, not rich, the car has a specific internal shape.
3, titanium alloy screw surface corrosion treatment refers to the use of various methods to play the maintenance of the metal surface, the role is the metal and corrosion environment isolation, to inhibit the corrosion process, reduce the contact between corrosive media and the metal surface, to prevent or slow down the purpose of corrosion.
Special attention should be paid to the selection of screw material technology:
1, screw material mechanical properties, strength requirements. Some screws need a relatively high strength, then choose the higher strength of the screw material itself.
2, working conditions of the material corrosion resistance performance requirements, a part of the standard network screws used in the above products with strong corrosion, which requires us to choose a strong spiral steel wire corrosion resistance.
3, the heat resistance of the material working temperature requirements. Some titanium alloy screws for high temperature operation, need to choose the screw material high temperature performance.
4. Performance requirements in the production process of material processing. Some titanium alloy screws in the production process need to deal with line, hardness and other difficulties, need to choose the appropriate screw material hardness, is conducive to processing and production.
5, the weight of the screw itself, price, procurement and other factors affecting the choice of screw material, due consideration of these areas of material is a better choice.
