Everyone may have some knowledge of the application of asphalt heating tanks. Today, we will introduce some unstable factors that occur when asphalt heating tanks are working. Let's take a look at them together.
There are three main manifestations of the instability of emulsified asphalt produced by asphalt heating tanks: inclined plate sedimentation tank, coalescer and foundation settlement. The asphalt storage tank uses L-band heat (high-temperature heat transfer oil) as the heat transfer medium, raw coal, natural gas or oil furnace as the heat source, and the hot oil pump is forced to circulate the system to heat the asphalt to the adopted temperature.

Asphalt heating tanks are also known as colorful binders. They are imitating modified asphalt ingredients and are made of petroleum resins and SBS modified materials and other chemical raw materials. This type of asphalt itself is not colorful or colorless, but dark red. In recent years, it has been commonly called colored asphalt pavement due to market habit. The asphalt heating tank breaks the electrostatic induction (a positive charge in a static state) repulsion of the double electric layer and gathers together, which is called the inclined plate sedimentation tank. At this time, as long as mechanical stirring is carried out, the asphalt heating tank particles can be separated again. It is a reversible process.
The emulsified asphalt particles gathered together after the asphalt heating tank inclined plate sedimentation tank are fused into a large-sized asphalt heating tank called agglomerator. The emulsified asphalt particles that form the agglomerator cannot be separated by simple mechanical stirring. This process is irreversible.
With the continuous increase of asphalt heating tanks, the particle size of asphalt heating tanks has gradually increased, and the large-sized asphalt heating tanks have settled under the action of force. In order to better store asphalt heating tanks stably, it is necessary to avoid the three types of instability of the inclined plate sedimentation tank, agglomerator and settlement of emulsified asphalt.
