Acid And Alkali Resistant Conveyor Belt Features: cotton canvas, nylon canvas or polyester canvas as the core, with good elasticity, good groove performance and low elongation. The coating adhesive made of acid-alkali resistant material has good chemical resistance and physical properties.
Application: Suitable for conveying corrosive materials containing acid in a chemical plant, chemical fertilizer plant, paper mill, etc.
Acid and alkali resistant conveyor belt (acid and alkali resistant conveyor belt) is suitable for a working environment in contact with acid and alkali, such as phosphate fertilizer manufacturing, seawater salt. An acid-alkali resistant conveyor belt (acid-alkali resistant conveyor belt) covering adhesive is made of rubber and plastic mixed and filled with material with excellent alkaline nature, which is better than neoprene in the acid-alkali resistant conveyor belt. The skeleton material adopts polyester canvas, which is more reliable than cotton canvas core belt in resisting acid and alkaline.
Baoxiang is a multifunctional conveyor belt manufacturers that integrates production line development, manufacturing, debugging and technical transformation. Its products include conveyor belting, nylon conveyor belt, etc.
