The Explosion Hazard Research of the Polyethylene Dust

[摘要] The aim of the article is to point out the dangers arising from the properties of plasticdust and what influence its properties have on the origin and course of the explosion.The present project analyzed the sample of polyethylene dust,by-product of granulateproduction and storage. The explosion tests were performed on containers of a similarshape to those found in a plants. By examining the properties of plastic dust and itsbehavior in the event of an explosion we have observed that the risk of explosion intechnological equipment can not be underestimated. Knowledge about explosiveness ofdust samples will be used in comprehensive safety solution of a particular technologicalnode.
