Why the UHMWPE layer of impact bars are not wear resistant ?


Honestly, there are many reasons cause the "non wear resistant "  of the conveyor impact bar, such as the self quality problem, install problem, etc. 


The self quality problem of impact bar.

1.  Some suppliers provide low weight of UHMWPE molecular, which cause the poor wear resistant performance of the impact bar. 

2. Less elastic of the rubber components, to reduce cost, some suppliers may use reclaimed rubber, which has poor impact resistant performance. 

3. The prblem of adhesive strength. The unqualified vulcanization technology will cause the adhesive problem between UHMWPE layer and rubber. 


Unreasonable design of impact bar for conveyor.

1. The unreasonable design of impact bar will cause it fast wearing.

2. Improper selection model of impact bed  cause the impact bed and bar can't bear the impact force higher than design value, increase replacement frequency.
