CHEMICAL RESISTANT CONVEYOR BELT
It is suitable for chemical plants, chemical fertilizer plants, paper mills and other factories and mining enterprises to transport corrosive materials such as acid and alkali.
1. Cotton canvas, nylon canvas or polyester canvas are selected as the core. The belt has good elasticity, good grooving performance and small elongation.
2. The coating is made of acid and alkali resistant materials, which has good chemical corrosion resistance and good physical properties.
Accelerated aging test of rubber physical properties in hot air (test condition: 50 ℃ × 6 hours).
|Level||Solution||Concentration||Coverage Status||Change Rate Before And After Coverage|
|Volume Expansion Rate||Strength Change Rate|
|A1||(HCI)||18%||50°C X 96h||≥10%||≤10%|
|A2||(H2S04)||50%||50°C X 96h||≥10%||≤10%|
|A3||(NaOH)||48%||50°C X 96h||>10%||<10%|
|Item||Breaking strength||Elongation at break||Abrasion||Hardness|
|Properties before aging||≥14.0||≥400||≤250||60 + 10/-5|
|Properties after aging||≥12.0||≥350||-||65 + 10/-5|
When the covering adhesive thickness is 0.8mm-1.6mm, the thickness of the sample can be the maximum cutting length, and the tensile strength and elongation at break are allowed to be 15% lower than those in the table.
