Surface treatment of metal wiper blades: the key role of coating technology

In the design and manufacturing process of metal wipers, the treatment of the blade surface is a crucial link. This is not only related to the performance of the wiper, but also directly affects its service life and the protection of the clean surface. Among them, the application of blade surface coating technology has played a key role in improving the performance of metal wipers.

First, let us understand why the blade surface needs coating. During long-term use, metal blades are prone to react with moisture, oxygen in the air, and other chemicals, resulting in corrosion and wear. This will not only shorten the service life of the blade, but may also cause scratches when in contact with the clean surface, damaging the surface quality. Therefore, by adding a coating, the corrosion resistance and wear resistance of the blade can be effectively improved.

The application of coating technology brings many benefits to metal wiper blades. On the one hand, the coating can isolate the blade from contact with harmful substances in the external environment and reduce the occurrence of corrosion. On the other hand, the coating itself has high hardness and wear resistance, which can resist the friction and wear generated during the wiping process, thereby extending the service life of the blade.

More importantly, coating technology can also prevent the blade from chemically reacting with the clean surface during the wiping process. In certain specific scenarios, such as cleaning acidic or alkaline solutions, uncoated metal blades may react with chemicals in the solution to produce harmful substances, thereby damaging the surface. Coating technology can effectively prevent this reaction from occurring and protect the integrity and quality of the clean surface.

Of course, the selection and application of coating technology is also a science. Different coating materials have different performance characteristics, such as hardness, wear resistance, corrosion resistance, etc. Therefore, when selecting coating materials, it is necessary to comprehensively consider factors such as the use scenario of the metal wiper, the characteristics of the target surface, and the user's usage habits. At the same time, the preparation process of the coating also needs to be finely controlled to ensure that the bonding force between the coating and the blade substrate is strong enough and not easy to fall off.

The coating technology on the surface of the metal wiper blade is the key to improving its performance and service life. By selecting suitable coating materials and preparation processes, the corrosion resistance and wear resistance of the blade can be effectively improved, and chemical reactions with the clean surface during the wiping process can be prevented, thereby protecting the integrity and quality of the surface. In the future, with the continuous development and innovation of coating technology, it is believed that the performance of metal wipers will be further improved.
