New highlights of screws and countermeasures to aging and corrosion problems
Introduction: Screws, as fasteners, play an important role in various fields. With the continuous advancement of technology, some new highlights and innovations have appeared in screws. However, after long-term use, screws may suffer from aging and corrosion problems, affecting their performance and service life. This article will explore the new highlights of screws and introduce effective measures to solve the problems of screw aging and corrosion.
1. New highlights of screws:
Special thread design: The new generation of screws adopts a triangular circular thread design. The cross section of the thread has a front spiral tapered guide, which allows it to be better inserted into the prefabricated threaded hole and plastically deforms with the lamp body to form a stable connection. . This design also has anti-loosening and explosion-proof functions, bringing new technological breakthroughs to various application scenarios.
Surface treatment: In order to enhance the corrosion resistance of screws, the material can be surface treated before screw processing. For example, the galvanizing process can form a protective layer on the surface of the screw to prevent the penetration of corrosive media such as acids, alkalis, and salts, and improve the corrosion resistance of the screw.
2. Measures to deal with screw aging and corrosion:
Phosphate treatment: Phosphate treatment is a chemical treatment method that improves the corrosion resistance of screws by reacting with the metal surface to form a phosphate protective film. This treatment method can form a dense phosphate film, and form an underlying protective layer and coating cold adsorption lubricant on the metal surface, effectively reducing the occurrence of corrosion.
Regular maintenance and cleaning: For screws that are exposed to harsh environments for a long time, regular maintenance and cleaning are necessary. Timely remove dirt and rust on the surface of the screws to keep the screws in good condition and extend their service life.
Use corrosion-resistant materials: In some special environments, you can choose screws made of corrosion-resistant materials, such as stainless steel screws. These materials have excellent corrosion resistance and are capable of long-term use in harsh conditions.
Conclusion: New highlights of screws include special thread design and surface treatment technology. These features improve the performance and corrosion resistance of screws. To deal with the aging and corrosion of screws, measures such as phosphate treatment, regular maintenance, and the use of corrosion-resistant materials can be taken. In actual applications, select appropriate screws according to specific needs and follow correct maintenance and cleaning methods to ensure their stable performance and extended service life.
