The role of vitrified microbeads in thermal insulation mortar
Key words
Vitrified microbeads, thermal insulation mortar, acrylic emulsion
Introduction
Vitrified microspheres are due to the surface vitrification to form a certain particle strength, the physical and chemical properties are very stable, the aging resistance and weather resistance are strong, and they have excellent thermal insulation, fire resistance, and sound absorption properties. ﹑ sound-absorbing and thermal insulation materials. In the building materials industry, the use of vitrified microbeads as lightweight aggregates can improve the fluidity and self-resistance strength of mortar, reduce the shrinkage rate of material properties, improve the overall performance of products, and reduce overall production costs.
Vitrified microbead thermal insulation mortar is a new type of inorganic thermal insulation mortar material used for external wall insulation. It has the remarkable characteristics of high strength, light weight, good heat preservation, good heat insulation, good electrical insulation performance, wear resistance, corrosion resistance and radiation protection.
Materials required for vitrified microbead insulation mortar

Scope of application
Vitrified microbead thermal insulation mortar is suitable for energy saving projects of 50% and 65% energy saving in heat in summer and cold in winter, hot in summer and warm in winter, and for newly-built, renovated and expanded public and civil buildings in external walls and roof insulation and energy-saving projects.
The finish is the exterior insulation of paint and tiles.
Internal insulation layers including stairwells, household partition walls, kitchen toilets, closed balconies, ceilings and other maintenance structures.
Insulation layer of steel structure building, insulation layer of special-shaped structure of building.
Insulation padding for the inner layer of the dry hanging finish.
Ground insulation, roofing, planting roof, wood structure roof insulation.
