Choosing the Right Chemical Resistant Conveyor Belt: Essential Features and Their Importance

Choosing the Right Chemical Resistant Conveyor Belt: Essential Features and Their Importance

When selecting a chemical resistant conveyor belt, especially for environments exposed to acids and alkalis, it’s crucial to understand the key features that ensure long-lasting performance and safety. Whether it's for phosphate fertilizer manufacturing, sea water salting, or any other industrial applications, a properly designed conveyor belt can make a significant difference. In this blog, we’ll discuss the essential features of an acid and alkali resistant conveyor belt and why they matter for your operations.


1. Durability in Harsh Chemical Environments

One of the most important aspects of a chemical resistant conveyor belt is its ability to endure exposure to corrosive materials like acids and alkalis. Rentone Belt manufactures belts with top and bottom covers made of highly acid and alkali-resistant rubber, designed to withstand challenging environments without degrading. Whether it's hydrochloric acid or sulfuric acid, Rentone’s conveyor belts maintain their integrity, even when exposed to solutions up to 50% concentration at elevated temperatures.

2. Tensile Strength and Elongation Rate

A crucial factor in selecting a belt from a conveyor belt factory is its tensile strength and elongation rate. A high tensile strength, such as 14.0 MPa or greater, ensures that the belt can handle heavy loads without breaking. The acid and alkali resistant conveyor belts from Rentone exhibit excellent flexibility, making them suitable for various industrial applications. Additionally, the small elongation rate minimizes stretching, preserving the belt’s shape and ensuring better load handling and reduced maintenance.

3. Wear Resistance and Hardness

The wear resistance and hardness of a conveyor belt determine its ability to endure mechanical stress, abrasion, and damage over time. Rentone's belts meet high wear resistance standards with a volume wear rate below 250 mm3. The hardness level, between 55-70 AO, strikes the perfect balance between flexibility and strength, allowing the belt to be durable without becoming too rigid. These characteristics are essential for industries that demand long operational life and reduced downtime.

4. Acid and Alkali Resistance Test Standards

The resistance of a conveyor belt to acids and alkalis is typically measured under controlled conditions. Rentone Belt products adhere to the HG/T 3782-20 executive standard, ensuring superior quality. According to testing, the volume expansion rate and tensile strength of the belts change within acceptable limits (+10% and -10%, respectively) after prolonged exposure to hydrochloric acid, sulfuric acid, and sodium hydroxide at high concentrations. This ensures that the belt remains reliable even after continuous exposure to corrosive substances.
