We all know that titanium screws are easy to rust when exposed to the air, so titanium screws need to be moisture-proof and moisture-proof. Let's talk about it in detail below:


1. The choice of component insulation dipping varnish, such as epoxy resin or polyurethane dipping varnish. Choose paint that does not contain volatile acids. The vibration machinery uses solvent-free paint.


2, The use of melamine alkyd paint, it should adjust the curing temperature and curing time, the curing temperature is slightly higher than 130 ℃ (such as 135 ℃) and the curing time is more than 180 minutes is appropriate, the process needs to be strictly implemented, especially in the hot and In the wet season, because of the concept of rust, the conventional drying (curing) time of the sample paint factory is not necessarily abundant, and the car has a specific internal shape.


3. Surface corrosion treatment of stainless steel screws refers to the use of various methods to maintain the metal surface of the layer. Its role is to isolate the metal from the corrosive environment to inhibit the corrosion process, or to reduce the contact between corrosive media and the metal surface to prevent or The purpose of slowing down corrosion.

At the same time pay special attention to the screw material selection technology:


1. The mechanical properties of the screw material, especially the strength requirements. Some screws need a relatively high strength, and then choose the higher the strength of the screw material itself.


2. The requirements of material corrosion resistance for working conditions. Part of the screws of the standard network are used for the above-mentioned products with strong corrosion, which requires us to choose the corrosion resistance of the strong spiral steel wire.


3. The working temperature (high temperature strength, oxidation resistance) requirements of the material's heat resistance. Some screws are used for high temperature operation, which requires us to choose the high temperature performance of the screw material.


4. Performance requirements in the production process of material processing. Some screws are better processed in the production process, some are difficult, and all aspects of hardness are relatively difficult. This requires us to choose the appropriate hardness of the screw material, which is conducive to processing and production.


5. Other aspects, such as weight, price, and purchase factors should be considered. The weight of the screw itself, price, purchase and other factors affect the choice of screw material, and proper consideration of screw material in these areas may be a better choice.
