Choose cotton canvas, nylon canvas or polyester canvas with core, with body good elasticity, good groove performance, small elongation. The acid-alkali resistant material has good chemical corrosion resistance and good physical properties.

2: Use

Acid-alkali resistant conveyor belt (acid-alkali resistant conveyor belt) is suitable for the working environment in contact with acid and alkali, such as phosphate fertilizer manufacturing and seawater salt exposure. Acid-alkali resistant conveyor belt (acid-alkali resistant conveyor belt) adopts rubber-plastic mixed and filled with excellent inert material, which is better than neoprene rubber acid-alkali resistant conveyor belt. The skeleton material uses polyester canvas, than cotton canvas core with acid and alkali resistance performance is more reliable, generally made of ring

3: Performance indicators

project	Longitudinal tensile strength / MPa	Longitudinal pull elongation /%	Acid – base coefficient was 15 – 25℃ for 24h	Interbetween bonding / N/MM	Glglue with the cloth / N/MM	Wear consumption / MM3
data	≧15	≧400	≦0.8	≧4.5	≧6	≦120

4: Execute standards

HG/T 3782-2005

The overlay is divided into three categories: A1, A2 and A3 according to their acid-base resistance.

class	Soak the solution	potency	steeping condition	Performance change
				specific volumetric dilatation	change rate of strength
A1	hydrochloric acid	18%	50℃×96H	≦+10%	≦-10%
A2	sulphuric acid	50%
A3	caustic soda	48%
