Application Method
This application was carried out based on Belzona Know-How System Leaflets FPA-10 and FPA-1. Surface was prepared through mechanical scarification. After cleaning, the surface was conditioned with Belzona 4911. After that, Belzona 4111 and Belzona 4151 were applied by injection technique. These products have excellent adhesion, vibration and compression resistance and are superior to convencional concrete in order to minimize the effects of wear (gaps) at the base of anchor bolts.
Belzona Facts
Following data was found through vibration analysis: Before application – average vibration of 10.57 mm/s². After application – average vibration of 3.38 mm/s². Based on that, it was concluded that Belzona’s technology reduced the vibration effects on the equipment by 1/3.
