(3) The heat conductivity coefficient is small, and is almost the same as that of the base layer and the first-impression concrete building block
The plastering gypsum belongs to a porous structure, and the pore structure is uniformly distributed, so that the heat conductivity coefficient is small (less than 0.22) and is close to (about 0.23) that of an aerated concrete block, and the two materials are favorable for avoiding hollowing and cracking caused by too large deformation difference caused by thermal expansion and cold contraction; meanwhile, the heat-insulating material has a good auxiliary heat-insulating effect. The coefficient of thermal conductivity determines the coefficient of linear expansion, the coefficient of thermal conductivity of cement (0.93) is not much different from that of the aerated concrete upper building block, and temperature stress difference can be generated when the temperature changes, so that the aerated concrete wall can crack and fall off in a large area after one or two years.
(4) High adhesion strength, and suitability for various base surfaces
The adhesive property is good, so the adhesive is suitable for base layers made of various materials, and the surface of the smooth base layer is not required to be brushed or napped.
Cement mortar must be given away thick liquid earlier on smooth basal plane in batches, and the basic unit of napping is handled, great increase material and cost of labor, cement interfacial agent is glued moreover mostly, glues to be the organic matter, easy ageing.
(5) Has good water retention property and is not easy to pulverize
The porous structure of the plastering gypsum has the characteristic of good water retention, and the plastering layer is like a wall with breathing function and can automatically adjust the self dry humidity of the inner wall surface, thereby maintaining a healthy indoor environment
Cement mortar water retention is poor, and moisture runs off soon, and meets humid weather and can form the comdenstion water, can make indoor air moist to aggravate human moisture, seriously influence health.
