Study on the corrosion resistance of Aramid conveyor belt

In the material transportation system of modern industry, the conveyor belt faces a variety of working environments, among which the corrosive environment has a significant impact on the service life and performance of the conveyor belt. Aramid conveyor belts show unique advantages in corrosion resistance and are worthy of in-depth study.

Aramid materials have a stable chemical structure. The chemical bond energy between its molecular chains is strong, which makes it difficult to react chemically with common corrosive substances. For example, in the chemical industry, many materials are acidic or alkaline, and conveyor belts are often exposed to corrosive chemicals such as hydrochloric acid, sulfuric acid, and sodium hydroxide. Ordinary conveyor belt materials may be corroded in a short time, resulting in reduced strength and surface damage, while Aramid conveyor belts can better resist the erosion of these chemicals.

From a microscopic point of view, the surface of aramid fiber is relatively smooth, which reduces the chance of corrosive substances adhering to and penetrating its surface. When corrosive liquids or gases come into contact with the Aramid conveyor belt, it is difficult to penetrate into the material to destroy its structure. At the same time, the low water absorption of aramid itself also contributes to its corrosion resistance. Lower water absorption means that less water can enter the material, thereby avoiding the situation where corrosion is accelerated due to corrosive ions carried by water.

In actual application scenarios, such as port transportation facilities in marine environments, the air contains salt, which is highly corrosive to conveyor belts. Aramid conveyor belts can maintain stable performance for a long time in such an environment. However, this does not mean that they can resist all corrosion factors. In some extremely corrosive environments, such as high-concentration special highly corrosive solutions or long-term exposure to a complex environment where multiple corrosive substances are mixed, the corrosion resistance of Aramid conveyor belts may also face challenges. Therefore, during use, reasonable maintenance and monitoring are still required according to the specific working environment to ensure that they always maintain good corrosion resistance.
