A method for repairing inorganic thermal insulation mortar system

Abstract

A method for repairing an inorganic thermal insulation mortar system, which relates to the field of thermal insulation of building walls, comprising step 1, setting a slot that runs through the inorganic thermal insulation mortar system, and the bottom of the slot is the base wall; step 2, removing the surface of the inorganic thermal insulation mortar system Respectively expand and extend to the top and bottom of the slot to form an expanded surface, extend the expanded surface to the plaster layer, and expose the mesh cloth, that is, the expanded mesh cloth; Step 3, install water-proof in the slot strip, and bond the inner side of the water-separating strip to the bottom of the groove; step 4, lap the outer side of the water-separating strip with the expanded grid cloth, and apply the plastering glue to form a protective layer; step 5, apply the inorganic The surface of the thermal insulation mortar system shall be repaired according to the original finishing requirements. The present invention relates to a method for repairing an inorganic thermal insulation mortar system. Grooving can effectively release the stress of the inorganic thermal insulation mortar system; it can effectively block the spread of water on the wall, quickly reduce the water seepage area, and protect the inorganic thermal insulation mortar system.

[0003] The current inorganic thermal insulation mortar system adopts the method of whole-surface construction. During construction, the volatilization of inorganic thermal insulation mortar mixing water causes dry shrinkage stress, and thermal expansion and contraction after completion will cause temperature stress. If these stresses cannot be effectively released , will form cracks at the stress concentration parts, and at the same time, various cracks will be caused by the irregular settlement of the wall; these cracks will cause water seepage danger: the finish layer of the inorganic thermal insulation mortar system is generally made of paint, real stone paint or colorful finish , these finishes cannot effectively relieve the release of stress, nor can they prevent external water from sending cracks into the inorganic thermal insulation mortar system; at the same time, the inorganic thermal insulation mortar system has a relatively high water absorption rate, which is easy to store water, and the internal porosity is large. It flows down the wall and spreads to the entire wall, so that the water seepage point cannot be found effectively during maintenance, so it can only be completely removed

It is difficult to maintain the inorganic thermal insulation mortar system, which is mainly reflected in the difficulty of finding the leakage point. The failure is mainly reflected in the water ingress inside the system, which leads to a great reduction in the overall insulation effect, and the internal water ingress causes the material to soften, and the bonding strength of the materials composed of the system is reduced, resulting in Shedding hazard
