The reason why polypropylene high strength yarn can stand out among many fiber materials and show excellent corrosion resistance, from the depth of material science and chemical principles to analyze, mainly due to the following closely related and crucial key factors. These factors are intertwined and synergistic, not only to build a stable protective barrier at the microscopic molecular structure level, but also to give polypropylene high-strength filament excellent ability to resist various types of corrosive media erosion in the macro performance, making it one of the ideal materials for many applications with strict requirements for corrosion resistance.

The reason why polypropylene high strength yarn shows excellent corrosion resistance is mainly attributed to the following key factors:

1. Chemical structure characteristics

Polypropylene high strength filament is made of polypropylene. The molecular chain of polypropylene is mainly composed of carbon-hydrogen (C-H) bond, which has high stability. In many corrosive environments, such as acid-base solutions, carbon-hydrogen (C-H) bonds do not readily react chemically with acids or bases. For example, in common dilute sulfuric acid, hydrochloric acid, sodium hydroxide and other solutions, the chemical structure of polypropylene high-strength filament can remain intact, unlike some metal materials that will be corroded by acids or alkalis, resulting in metal ions and gradually damaged.

2, non-polar molecular properties

Polypropylene is a non-polar molecule. This makes the polypropylene high-strength filament have a good tolerance to polar solvents. Many corrosive substances, such as some organic or inorganic acids, bases, salt solutions containing polar groups, are difficult to interact with the non-polar molecules of polypropylene high-strength filaments. For example, in some salt solutions containing chloride ions, metal materials are prone to electrochemical corrosion, but polypropylene high-strength filament, due to its non-polar molecular structure, will not form electrochemical corrosion batteries like metals, thus avoiding the risk of corrosion.

3, no active groups

The molecular structure of polypropylene high strength yarn has no active groups such as hydroxyl (-OH), carboxyl (-COOH), amino (-NH), which are easy to react with corrosive substances. These active groups are relatively active in many organic and inorganic chemical reactions and are easy to be oxidized, hydrolyzed or other chemical reactions. The polypropylene high-strength filament does not have these active groups, which reduces the chance of reacting with external corrosive substances, so that it can maintain good performance in a corrosive environment.
