Update time：2017-09-08 00:44:10clicks：2029次Type size：T|T
The application of inorganic materials in external wall insulation engineering has always been controversial. Inorganic thermal insulation material formed by adding a certain proportion of phase change material with inorganic material as the main carrier is put through the field coating construction, and the last coating is pressed into the alkali resistant mesh cloth. Enterprises that provide phase change insulation materials generally introduce that 40-50mm can achieve the design requirements of building energy saving 65%,
This is doubtful. According to the phase transformation mechanism, when the temperature exceeds a certain level, the solid will transform into the liquid phase, and the material will absorb heat. When the temperature is reduced to a certain temperature, the material starts to release heat from the liquid phase to the solid phase, and maintains a relatively stable temperature in a certain space through heat absorption and heat release.
Inorganic vitrified microbeads are the in-depth processing products of perlite, an early thermal insulation material in the construction market. Vitrified microbeads are closed cell light materials with high closed cell ratio, low water absorption and thermal conductivity of about 0.07W /m.k. Because of its high thermal conductivity, it is mostly used in the southern market, and it is not suitable for large-scale application in cold and severe cold areas. When the vitrified microbead insulation mortar is in construction, it has strong adaptability to the base of the wall and can be directly smeared and smooth without being affected by the foundation modeling. The system can realize the whole seamless construction, avoid the joint problems of other insulation plate construction, the stress distribution and release after construction are uniform, the construction disadvantage is that the on-site mixing quality is not easy to control, and the construction environment is greatly affected.

Introduction to the use of inorganic insulation mortar in Shanghai:
Inorganic thermal insulation mortar has a long history of use in the construction of thermal insulation projects, and when the earliest construction energy-saving implementation of 30% standard, it has been used in many internal thermal insulation projects. Later, with the progress of energy-saving planning standards and the high water absorption rate of inorganic thermal insulation mortar, the thermal insulation effect is not simple to control and other shortcomings gradually decreased. Inorganic thermal insulation mortar currently reflects the best
The vitrified microbeads are the vitrified microbeads thermal insulation slurry composed of cement, redispersible powder, anti-cracking fiber and other materials. Compared with the perlite insulation aggregate with open pores, the vitrified microbeads have higher closed porosity, water absorption and lower thermal conductivity. The thermal conductivity of vitrified microbead insulation mortar can be controlled within 0.07w/m.k, but compared with organic and efficient inorganic insulation materials, there is still a large distance.
Therefore, the inorganic thermal insulation mortar system represented by vitrified microbeads can achieve the planning requirements of 65% energy saving in the northern region, and its thickness will exceed 100mm, which is obviously not suitable for large-scale use in the northern region. According to the energy-saving planning requirements of hot summer and cold winter areas and hot areas, it is suitable to use in the southern region. Usually 30-50mm can be satisfied with the current period of class A fire prevention and insulation of the two layers of demand. However, it is also necessary to control the water absorption of inorganic thermal insulation mortar. The inorganic insulation mortar without hydrophobic treatment simply presents the dry shrinkage cracks caused by repeated dry and wet replacement. The high water absorption rate in the winter low temperature season also simply presents freeze-thaw damage, so that the insulation project presents empty drum, cracking, water seepage and other engineering drawbacks.以上翻译结果来自有道神经网络翻译（YNMT）· 通用场景
