The following analysis of the cause of the failure of the epoxy floor roll:
1. The concrete marking is too low and fails to meet the national technical standards, which will lead to ground sanding, dusting, looseness, and lack of strength;
2. When the concrete is poured at the site, failure to comply with the standard construction work will lead to sanding, dusting, looseness, and lack of strength on the ground. After the construction of the concrete floor is completed, failure to timely maintain or maintain the soil will cause sanding on the ground. Dust, looseness, no strength, etc.;
3. Before the concrete floor is used, it is not treated as a plain ground. With the use of a long time, especially in the use of forklifts or trailers with high frequency, the ground will be very fast due to the effects of carbonization, water erosion and weathering. Sanding, dusting, looseness, etc.
