Acid and Alkali Resistant
Acid and Alkali Resistant conveyor belt
I. Features:
Use cotton canvas, nylon canvas or polyester canvas as carcass, with body flexibility is good, good performance into the groove, using small elongation. Selection of materials processed into acid coating, has good chemical resistance and good physical properties.
2. Purposes:
For chemical plants, chemical plants, paper mills and other factories and enterprises such as transport acidic or alkaline corrosive material.
