Expanded vitrified microspheres are the core aggregate in expanded vitrified microsphere thermal insulation mortar, which play the role of thermal insulation. What is the appropriate amount of re-expanded vitrified microsphere thermal insulation mortar? How can we achieve the best thermal insulation effect?
The amount of expanded vitrified microspheres in the expanded vitrified microsphere thermal insulation mortar has a great relationship with the quality of the expanded vitrified microspheres themselves. The quality problem of the expanded vitrified microbeads itself is mainly reflected in the fact that many current expanded vitrified microbeads manufacturers cannot meet the process and various requirements, so the expanded vitrified microbeads are not completely closed and the strength of the expanded vitrified microbeads is too low. This affects the quality of its expanded vitrified microsphere thermal insulation mortar. Currently, the expanded vitrified microbeads on the Chengdu market generally have a bulk density of 110KG/M3 (9 bags per cubic meter, basically 11kg per bag). But the actual situation is basically about 120KG/M3 (8 bags per cubic meter). In order to meet the requirements for dry density, strength, thermal conductivity and other performance indicators of thermal insulation mortar, the dosage of expanded vitrified microspheres of different qualities must be determined.
