A new high-performance thermal insulation material, foam glass, has begun to be applied in construction engineering. Black pearl-foam glass, which is known as energy-saving engineering, has been widely used in the insulation and sealing of roofing and exterior walls of chemical thermal insulation, shipbuilding, refrigeration, cold storage, subway and constant temperature and humidity engineering, and general industrial and civil buildings. Insulation engineering. In the past, China has only used thermal insulation projects for chemical deep-cooling equipment, ships, and cold storage. In recent years, it has begun to be used in construction projects. Foam glass is a light-weight, independent closed-cell foam produced by firing foamed quartz sand or pulverized glass powder. Because it is a closed-cell foam glass of inorganic material, it has small thermal conductivity and stable adiabatic function; no water absorption, low water vapor permeability; excellent high temperature resistance and durability; high strength, light weight, small deformation; no burning , non-corrosive; can be cut and formed, easy to construct; can be made into colored materials, with beautifying environmental functions; can be firmly bonded with the base layer with polymer cement mortar. Compared with the insulation materials currently used in construction projects, foam glass has unique characteristics for roofing, can form a permanent thermal insulation layer, and, because of its excellent weather resistance, is especially suitable for inverted roofing. Insulation layer. After the polymer cement mortar is bonded and jointed, a complete waterproof layer can be formed to protect the water. When used for exterior walls, it can be directly bonded with polymer cement mortar, which is convenient for construction. For example, the use of colored foam glass not only serves as thermal insulation but also as a decorative material, it is a good method. Building energy conservation is an extremely important policy of the country. It is a systematic project that benefits the country and the people and benefits future generations. Strengthening the thermal insulation of buildings is a direct and practical way to improve people's working and living environment conditions and save energy. In China's building thermal insulation engineering, high water absorption and poor durability of thermal insulation materials have always been two major problems. It greatly reduces the insulation performance of the material, affects the effect of thermal insulation, and increases the energy consumption of the air conditioning system. Moreover, after the water is absorbed, the heat insulating layer becomes an aquifer, which causes the waterproof layer to be damaged by the drum, causing leakage, and leaking water for a long time after the rain. In the external wall structure, due to the need of thermal insulation, the wall needs to be thickened to meet the functional requirements. Since there is no thermal insulation material that can replace the original red brick as the wall material, only the external insulation material can be used for insulation. Insulation, so it needs lightweight, good insulation, anti-aging, non-absorbent, easy to bond materials, foam glass is the most ideal insulation material. Foam glass, whether used for roofing or exterior walls, is an excellent thermal insulation material. When foam glass is used for the thermal insulation layer of the roof, since it does not absorb water, does not absorb moisture, and is stuck with cement mortar, water cannot enter, so it does not cause drum damage of the waterproof layer, and does not need to be exhausted. Holes do not have the problem of degraded performance after long-term use. It has a certain strength and is not easily compressed. It is used in new roofing types such as inverted roofs, sloped roofs, and planted roofs. It is unmatched by any other insulation materials. Foam glass is used for wall insulation, instead of red bricks, thinning the thickness of the wall, saving energy is second to none, and indirectly expanding the building area and reducing the building's own weight. It is pasted with ordinary cement mortar or polymer cement mortar during construction, and the adhesion is strong. For the outer wall paint surface layer, just apply a layer of cement mortar to level the foam glass layer. If colored foam glass is used, the foam glass can be cut into a certain size and directly pasted with polymer cement mortar.
