Grilled steak a stone wall paint 'short-lived' five main reasons

Stone coating is a kind of widely used in exterior architectural coatings products, accounting for the largest proportion of whole metope outer protective structure. Nowadays, environmental changes more and more intense, stone coating actually affected by more factors. The key point is stone coating accelerated aging, lead to actual quickly shorten service life. The following small editor and others will find five big stone wall paint 'short-lived' culprit: 1. External wall thermal stress mainly refers to the outer wall inside and outside temperature difference caused by the local forces, can cause systole of exterior expansion of structural changes, such as to be in a state of flux, increasing the coating latex material aging. Therefore, external wall thermal stress is listed as one of the main external causes shorten stone coating life. Compared with the multilayer buildings and factories, the outer surface of the high-rise building, generally larger, or more the number of exposure in the sun. In exterior wall decoration design, therefore, suggest that choose flexible anti-crack performance of stone paint putty, in order to improve the surface of the stone coating resistance to deformation ability. 2. Decoration of wind pressure in general, outside wall is wind generate thrust, and negative suction wind. These two forces can lead to high stone paint surface cracking and infiltration rainwater, mud, etc. In order to make the really stone paint has a certain resistance to wind pressure, stone paint construction no empty drum and layered problems, negative air pressure volume expansion might damage the outer wall of basement wall. 3. Environmental water vapor to avoid water damage of high-rise building, should choose not bibulous, hydrophobic good stone coating, in order to avoid water wall moisture content increased in the process of migration issues, improve water resistance and freeze resistance of stone coating. 4. High-rise buildings are more stringent than multi-storey building fire prevention requirements. Exterior wall stone coating should have good fire retardant function, to prevent the fire spreading, don't smoke or toxic gases. In addition, you should solve the problem of surface crack, flake coating, otherwise it's easy to create difficulties to residents of the rescue work. 5. Ground motion landmark seismic force will cause deformation of the high-rise building structure and exterior wall coating. Stone paint on the surface of the solid, under earthquake force is, the greater the damage is more serious. This requires stone coating on the premise of guarantee the adhesion, meet the requirements of flexibility, reduce the load of surface layer, the prevent large area crack, flake, or even fall off under the influence of surface vibration.
