Application of closed cell foam glass in construction engineering foam glass, a new type of high-performance thermal insulation material, has been applied in construction engineering

foam glass has been widely used abroad in chemical thermal insulation, ship, refrigeration industry, cold storage, subway and constant temperature and humidity projects, as well as the thermal insulation and heat insulation of roofs and exterior walls of general industrial and civil buildings. In the past, our country only used it for chemical cryogenic equipment, ships and cold storage to carry out compression tests. There is a sealing ring between the piston and the oil cylinder for thermal insulation. In recent years, it has been used in construction projects

foam glass is a kind of foam with light volume weight and independent closed cell, which is produced by firing quartz sand ore powder or broken glass powder. Because it is a closed cell foam glass of inorganic materials, it has small thermal conductivity and stable thermal insulation function; No water absorption, low water vapor permeability; Excellent high and low temperature resistance and durability; High strength, light weight and small deformation; No combustion and corrosion; It can be cut and shaped to facilitate construction; It can be made into color materials and has the function of beautifying the environment. Polymer cement mortar can be used to firmly bond with the base course. Compared with the thermal insulation materials currently used in construction projects, foam glass has unique characteristics. When used on roofs, it can form a permanent thermal insulation layer. Moreover, due to its excellent weather resistance, it is especially suitable for the thermal insulation layer of inverted roofs. After the polymer cement mortar is used for bonding and pointing, a complete waterproof layer can be formed to play a waterproof role. When used for external walls, polymer cement mortar can be directly used for pasting, which is convenient for construction. For example, colored foam glass can not only play the role of thermal insulation, but also can be used as decorative materials, which is a good way to kill several birds with one stone

building energy conservation is an extremely important national policy and a systematic project that benefits the country and the people and benefits future generations. Strengthening the thermal insulation of buildings plays a direct and practical role in improving people's working and living environmental conditions and saving energy. In China's building thermal insulation projects, high water absorption and poor durability of thermal insulation materials have always been two major problems, which greatly reduce the thermal insulation performance of materials, affect the effect of thermal insulation and increase the energy consumption of air conditioning systems. Moreover, after absorbing water, the insulation layer becomes a water storage layer, which will make the waterproof layer bulge and damage, resulting in leakage, and still leak 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. At present, there is no thermal insulation material that can replace the original red brick as the wall material, and only external thermal insulation materials can be used for thermal insulation. Therefore, materials with light weight, good thermal insulation performance, aging resistance, non water absorption and easy bonding are required. Foam glass is a very ideal thermal insulation material. Foam glass is a kind of excellent thermal insulation material no matter it is used in roof or exterior wall
