Titanium alloy screws are prone to rust in bare air, so titanium screws need to do some work to prevent moisture and moisture. Let's do a specific analysis for everyone.
1. Selection of component insulation impregnating varnish, such as epoxy resin or polyurethane impregnating varnish. The coating is selected to be free of volatile acids. The vibration machine uses a solventless paint.
2, the use of melamine alkyd paint, should adjust the fixed-line temperature and fixed-time time, the fixed-line temperature is slightly higher than one hundred and thirty degrees and the fixed-time time is greater than one hundred and eighty minutes is appropriate, the implementation of strict procedures, especially In the hot and humid season, from the rusting point of view, the paint factory's regular drying time is not necessarily, there is a specific internal shape.
3. Titanium alloy screw surface corrosion treatment refers to the use of various methods to maintain the metal surface of the maintenance layer. The 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 prevent or slow down the corrosion. purpose.
At the same time, special attention should be paid to the selection of screw materials:
1. Mechanical properties of screw materials, especially strength requirements. Titanium alloy screws require a relatively high strength, and the strength of the selected screw material itself is higher.
2. Requirements for corrosion resistance of materials under working conditions. A part of the screw is used for the above-mentioned highly corrosive products, and it is necessary to select the corrosion resistance of the strong spiral steel wire.
3. The requirements for the operating temperature of the heat resistance of the material. Some screws require high temperature performance of the screw material for high temperature operation.
4. Performance requirements in the production process of material processing. Some of the better handling of the screw production process requires the hardness of the appropriate screw material to facilitate processing.
5, other aspects, such as weight, price, procurement should consider factors. Titanium alloy screws themselves vary in weight, price, purchase and other factors affecting the choice of screw material.
