How long is the shelf life of asphalt emulsifier?
Under normal circumstances, the shelf life of asphalt emulsifiers is longer than the shelf life of food, which is similar to the shelf life of cosmetics we usually use. It is no problem to use it for 2-3 years under the condition of proper storage.
In the production process of asphalt emulsifier, there will be some volatile auxiliary materials. Although they have been diluted or neutralized during the reaction process, these substances will still undergo some changes under the influence of ambient temperature after long-term storage. There is a certain shelf life.
How to use bitumen emulsifier that has expired? It is necessary to observe its appearance to see if it has changed too much. Use a tool to probe the bottom of the barrel to observe whether it is delaminated or water-separated. If there is no major change, adjust the amount of addition slightly. Just use it. If the appearance changes, please use with caution!
Therefore, we recommend that you calculate the proportion of asphalt emulsifier according to the production amount, purchase it quantitatively, and use it within the shelf life.
