Question:

What is the construction method of external wall thermal insulation mesh

nan

Answer:

7, As the reqiured length and width, the meshes are cut from the entire roll of fiberglass mesh, leaving the necessary length for lapping or partial stack. 8, It is cut in the centre of a clean flat, cutting must be precise. The cutted mesh must be rolled up, and not allowed to fold or tread. 9, The reinforcing layer is made in the external corner of buildings, which should be laid the inner side, each side is150mm. 10, When coating the polymer mortar in the first time, the surface of EPS board should be dry, removing the harmful substances or impurities on the board. 11, a layer of polymer mortar is scraped on the surface of polyphenyl board, the scraping area should be slightly larger than the length or width of mesh, the thickness should about 2mm. Except the requirement for edging, the polymer mortar is not allowed to coat at the side of polystyrene board. 12, After scraped off polymer mortar, the mesh should be disposed on it. The curved surface of mesh faces toward the wall, coating from the center to the surrounding so that the mesh embedded in a polymer mortar, mesh should not be wrinkled. After the appearance is dry, and then wipe on a layer of polymer
1, It needs specially-assigned person to compound the polymer mortar in order to ensure the quality of stirring. 2, open the bung by contrarotate, and then remix the adhesive with a stirrer or other tools to prevent the parting phenomenon of binder, you should stir moderately, so as not to render quality problems. 3, polymer mortar mix ratio: KL Binder: 425# sulphate aluminium cement: Sand (with a 18 mesh screen): 1: 1.88: 3.25 (weight ratio). 4, After cement and sand are measured by the bucket, pour into iron gray groove, and then mix evenly. And pour into binder in mix proportion, stirring evenly into gruel to prevent dissociation. It can appropriately add water due to the workability. 5, water is the concrete water. 6, polymer mortar should be used with the distribution, the deployed polymer mortar preferably is better to run out within one hour. Polymer mortar should be placed in a cool place to avoid sun exposure.
before pasting the mesh, the screed-coat should be scraped on the thermal insulation base, and then paste the mesh with the trowel gently pushed, and then a layer of cracking resistant mortar is scraped thinly at the outer layer of mesh, so that mesh in the outer layer of cracking resistant mortar plays a role in the cracking resistant. Besides, it can not first paste mesh and the withwash cracking resistant mortar.
I. Construction conditions: 1, the base wall is qualified by check and acception. Door and window frames, various family sevice line on the walls, downspouts bracket and built-in fitting are installed in the design. 2, the flatness of shear walls is checke by 2m guiding rule, when the maximum deviation is greater than 4, it should be leveled up by 20 thickness of 1: 3 cement mortar; when the maximum deviation is less than 4, it should be repaired and leveled up by 1: 3 cement mortar at the uneven place. 3, masonry walls should be leveled up by 20 thickness with 1: 3 cement mortar. 4, and the base wall and screed-coat should be dry. 5, the construction site ambient temperature and the wall surface temperature within 24 hours after the construction are not less than 5 ℃, the wind is not more than five class.
