Many users of emulsified asphalt do not understand why emulsified asphalt needs to be demulsified, nor do they know what it is useful for. Therefore, the editor of Sinosun Company, an emulsified asphalt equipment manufacturer, would like to take this opportunity to explain to you in detail the relevant knowledge of emulsified asphalt demulsification.
Usually, asphalt needs to be heated to a higher temperature before it can melt, so it needs to be constructed at high temperature. However, later people emulsified the asphalt used at high temperature through mechanical stirring and chemical stabilization methods, and diffused the asphalt into the tax type to liquefy it into a road construction material with very low viscosity and good fluidity at room temperature, that is, emulsified asphalt.

Since emulsified asphalt is used at room temperature, the water contained in it needs to evaporate before it can condense with the material into a whole. The basis for simply judging whether its water exists is to see whether its emulsified state still exists, that is, to see whether its emulsified state is damaged, that is, demulsification. As long as the emulsification is broken, it means that there is no water in the asphalt.
The length of demulsification time needs to be determined according to the actual use situation. However, if the demulsification time is too fast, it may be caused by excessive emulsifier activity or high water temperature. You need to adjust the amount of emulsifier used for emulsified asphalt in time and pay attention to the water temperature. If the emulsification time is too long and the emulsification does not occur after several hours, you need to consider whether the emulsifier activity and asphalt content are too low.
The above is the relevant knowledge about emulsified asphalt demulsification explained by Sinosun Company, an emulsified asphalt equipment manufacturer, and I hope it can be helpful to you.
