Hollow microsphere is a kind of spherical glassy mineral produced by special high temperature process. It is a kind of hollow inorganic material which is resistant to high temperature, light and heat insulation. It has light weight density and small thermal conductivity. At the same time, hollow microbead material has fireproof and thermal insulation. , sound absorption and other excellent performance. Compared with the traditional polyphenylene particles and ordinary perlite, the thermal insulation mortar made of inorganic material with vitrified hollow microspheres as the aggregate overcomes the fact that the expanded perlite has large water absorption and is easy to pulverize, and the volume shrinkage is high during the agitation of the slurry. , It is easy to cause low strength in the later stage of the product and hollow cracking. At the same time, it made up for the defects such as flammability, poor fire performance, poor workability, and large resilience in construction of polyphenylene particulate organic materials.
The single-component dry powder mortar formed by the vitrified hollow microspheres as the aggregate and the modified dry powder binder is homogeneous, has the advantages of heat preservation, anti-aging, waterproof, no hollowing, no cracking, high strength, good bonding performance, etc. Many features are obviously better than those of polyphenylene granules and ordinary perlite as lightweight aggregates. They are quick and fast, shorten the second plastering time, and greatly improve the comprehensive performance and construction efficiency of dry powder insulation mortar.
At the same time, the hollow microbead insulation mortar is particularly suitable for hot summer and cold winter and hot summer and warm winter areas, and the advantages of internal insulation are even more obvious. The main reasons for the use of hollow microbead insulation mortar in hot summer, cold winter and hot summer and warm winter areas are as follows:
1. In the air-conditioned season (air-conditioning period) in hot climate regions, the temperature difference between inside and outside is relatively small. The proportion of air-conditioning energy consumption caused by wall heat transfer is far lower than the proportion of internal heat energy generated by doors and windows (wet), and the impact of thermal bridges does not dominate the mainstream.
2. During the air-conditioning period, the minimum value of the outdoor air temperature is not always higher than the indoor thermal comfort temperature, and the frequency of the outdoor air temperature fluctuations frequently occurs with the thermal comfort temperature, which determines the hot summer and cold winter and hot summer and warm winter regions. The air-conditioning mode is still an intermittent mode in nature. For the areas that are generally hot and cold in winter and hot in summer and warm in winter, the type of wall insulation that is well-adapted for building is the internal insulation.
3. The internal thermal insulation wall can effectively prevent the destruction of the windy and rainy climate in the region (hot summer, cold winter and hot summer and warm winter regions) that cannot be resisted by the external thermal insulation wall, and does not affect the traditional building facade design, equipment and pipelines. Exterior and so on.
4, the internal insulation wall is relatively inexpensive.
5. Due to the high compressive strength, good construction performance, and easy construction of the second renovation, the vitrified hollow bead fireproofing and heat-insulating mortar is particularly suitable for external wall thermal insulation.
