| abstract |
Consumable bitumen packaging compounds are used in combination with bituminous materials, eg, at least one packaging material, such as polymers, plastics, and extenders, and a pure powder or salt or oxide And is physically and / or chemically bonded to the polymeric material so that the density of the packaging material prevents the material from floating on the surface of the molten material after melting To be adjusted. The packaging components are preferably selected to be compatible with bitumen. After transportation and storage, the packaging material can be impregnated directly into the end-use bitumen product, greatly avoiding the formation of polymer skin that accumulates on the surface of the molten material. |
