Description
Acid and alkali resistant conveyor belt parameters
According to the national chemical industry standard production
Suitable for contact with acid and alkali environment, such as
phosphate fertilizer manufacturing, seawater baysalt, covered with
rubber blending glue and fill inert material excellent acid-proof
alkaline, better performance than the neoprene acid and alkali
resistant conveyor belt. Skeleton materials adopt EP canvas, with
acid and alkaline can be more reliable than the cotton canvas core.
Generally make it ring.
Acid and alkali resistant conveyor belt performance seen in the
table below:
Project of tensile strength/Mpa or greater tensile elongation % or
greater abrasion quantity/mm3 hardness/(o) + *0 or less
- 5
Aging performance before *4.0 *0, **0, **0
After aging performance of *2.0 *****5
Note: when the cladding thickness 0.8 MMMM - 1.6 mm, the maximum
thickness of the specimen thickness can be produced, at this point,
tensile strength and tensile elongation allowed within *5% lower
than the values in the table.
Acid and alkali resistant conveyor belt cover layer, acid-proof
alkaline can see the table below:
Soak solution concentration soaking conditions category before
aging performance
Performance before and after soaking temperature X time rate of
change
The volume expansion ratio of the intensity of rate of change
A1 hydrochloric acid *8% below *0 ℃ x *6 h + *0% - *0%
A2 *0% sulfuric acid (*6 h + *0 ℃ below *0% - *0%
A3 *8% sodium hydroxide (*6 h + *0 ℃ below *0% - *0%
