The technical scheme of thermal insulation construction of vitrified beads thermal insulation mortar is sought.

(1) Vitrified microsphere thermal insulation mortar is a one-component dry-mixed high-performance inorganic wall insulation material composed of vitrified microsphere (VMB), cement and additives, which can be widely used in wall insulation engineering of new and old buildings and effectively improve indoor thermal environment. Thermal insulation system consists of thermal insulation layer and anti-crack protection layer. Vitrified microbeads (irregular spherical particles with closed surface and porous inside made of volcanic lava mineral materials through heating, expansion and vitrification cooling) are used as lightweight aggregate, instead of traditional ordinary expanded perlite and polystyrene particles as lightweight aggregate of thermal insulation dry-mixed mortar, and dry powder modifier is premixed to form one-component inorganic dry-mixed thermal insulation mortar, which can be used by adding water and stirring on site, and can be directly applied to the enclosure structure. Theory and engineering practice have proved that the thermal insulation project of glazed hollow bead thermal insulation mortar is a good measure to realize building thermal insulation and energy saving. 3. Inorganic vitrified microsphere thermal insulation mortar is suitable for internal and external thermal insulation of external walls of industrial and civil buildings, independent thermal insulation of basements, garages, stairs, corridors, fire exits and thermal bridges, leveling fire-proof layers or protective layers of EPS and XPS. To meet the requirements of 50% and 65% of building energy saving. The building height generally does not exceed100m; There are two types of external wall insulation systems: thermal insulation slurry is directly combined with foundation wall and compounded with other thermal insulation materials. Foundations can be reinforced concrete walls and masonry walls; Exterior wall decorative layer can be painted or bricked.
