STRESS INTENSITY ANALYSES OF SUPPRESSANT FILM IN ACTION OF NATURAL FORCES

Theoretical analysis of suppressant film covered on the open-air powder piles in a South steel cooperation is carried out by adoption of Dust—seal^TM81620 suppressant liquid.The main attention focuses on the stress intensity of suppressant film in action of natural wind force and rainstorm.According the distribution of the displacement and stress intensity,the destroyed situation can be obtained,which can offer guide to further judge the effect of this suppressant.
