Acid- and alkali-resistant fabric-cored conveyor belts are designed for use in environments where exposure to corrosive acid or alkaline media is a daily occurrence. They are ideal for continuous production processes conducted under such harsh conditions. These belts boast excellent resistance to chemical corrosion, superior groove-forming capabilities, high productivity, and relatively low costs—making them an indispensable choice for general applications. Widely used in industries like chemicals and heavy manufacturing, which often involve handling acidic or alkaline substances, these belts play a critical role in ensuring efficient and reliable operations.
Selection of Acid- and Alkali-Resistant Fabric-Cored Conveyor Belt Core Structures
The core body uses an integral skeletal material—polyamide or polyester fibers—as its framework, offering excellent toughness, high joint strength, and superior impact resistance.
Polyamide fibers are known as nylon and nylons in the United States, and as cotton fibers in China. Their basic properties are as follows:
(1) High strength and excellent impact resistance.
(2) High elasticity, excellent anti-fatigue performance, with a rebound rate of 98%-100%—its resistance to repeated deformation is second only to polyester.
(3) Poor heat resistance—when the temperature rises, the fiber's tensile strength decreases, and its thermal stability is inferior to that of polyester. After being heated at 150°C for 1 hour, the strength retention remains at 695.
(4) Excellent wear resistance, surpassing other fibers and outperforming polyester by up to four times;
(5) Poor light resistance—its amide bonds in the macromolecule are easily broken down by light, leading to a reduction in high polymerization degree.
