What are the common misconceptions in the production line of vitrified microspheres used in hot-melt road coatings?

Customers may use cement mortar production equipment to mix vitrified microsphere insulation mortar during use, resulting in a damage rate of over 40% for vitrified microspheres. This type of mortar does not meet national standards and greatly reduces the insulation effect. Of course, only processing cement powder and then mixing it with vitrified microsphere insulation mortar at the construction site is feasible, which is commonly referred to as a two-component vitrified microsphere insulation mortar production line. This method has its drawbacks. The damage rate of vitrified microbeads during transportation is very high. 2. The operation procedures of workers during the use of mortar mixers can also lead to the breakage of vitrified microspheres. 3. A simple mortar mixer with high unevenness can also lead to poor quality of insulation mortar. Based on the above reasons, the country is now promoting single component glass bead insulation mortar equipment.

Some customers may use drum mixers to mix small materials such as mortar and plastic powder with vitrified microbeads simultaneously, which will inevitably greatly reduce the mixing cost. Drum mixers are only suitable for simple mixing, and it is impossible to disperse mortar fibers and wood cellulose in a short period of time. Short fibers and wood fibers will clump together, which will affect the quality of vitrified microsphere mortar.

In summary, the so-called fully vitrified microsphere insulation mortar production line must have a mortar production line and a drum mixer that complement each other and are indispensable.
