What are the characteristics of thermal insulation mortar and its construction technology?

Nowadays, many building constructions use thermal insulation mortar. So what are the characteristics of thermal insulation mortar and what are the construction techniques? The editor will explain it to you in detail below.

1. Performance characteristics of thermal insulation mortar

1. The use of thermal insulation mortar can improve the thermal insulation construction of buildings. It becomes simple and shortens the construction period of insulation construction. When carrying out thermal insulation construction of buildings, inorganic thermal insulation mortar can be applied to the wall just like cement mortar. Therefore, using thermal insulation mortar will have obvious construction time advantages compared to using other thermal insulation materials for construction.

2. The thermal insulation mortar has a long thermal insulation life and excellent thermal insulation performance. Thermal insulation mortar can currently be applied to wall bases of various materials and is widely used in the exterior walls of buildings. It plays the role of exterior wall insulation and exterior wall interior insulation, and can effectively avoid the occurrence of cold and heat bridges in buildings. , its thermal insulation performance is quite reliable. In addition, thermal insulation mortar can have extremely high strength like cement mortar, and its service life can be consistent with the service life of the building. It is worth mentioning that the reliable insulation performance of thermal insulation mortar prevents the phenomenon of hot and cold bridges in buildings. Without hot and cold bridges, there will be no mildew spots in the interior of the building.

3. Insulation mortar has good flame retardant properties and is an environmentally friendly building material. It can be seen from the raw materials of thermal insulation mortar that thermal insulation mortar uses non-flammable inorganic materials as raw materials, so the flame retardant performance of thermal insulation mortar is still guaranteed. In addition, the raw materials of thermal insulation mortar are non-toxic and harmless inorganic materials. They do not contain various harmful substances and fully comply with environmental protection standards. It is a green, environmentally friendly and pollution-free thermal insulation material.

2. Insulation mortar construction technology

1. The surface of the base layer should be free of dust and oil pollution and influence Debris on adhesive properties.

2. In hot weather or when the base layer is dry, when the base layer absorbs a large amount of water, it should be moistened with water to make the base layer wet inside and dry outside, with no clear water on the surface.

3. Mix the special interface agent for the thermal insulation system evenly according to the water-cement ratio of 1:4, scrape it on the base layer, and pull it into a zigzag shape, with a thickness of about 3mm. , or spraying method can also be used.

4. Stir the thermal insulation mortar into a slurry according to the following formula: rubber powder: polystyrene particles: water = 1:0.08:1. It should be stirred evenly without any lumps.

5. Powder the thermal insulation mortar according to energy-saving requirements. It needs to be applied in batches for more than 2cm. The interval between two plasterings should be more than 24 hours. Spraying method can also be used. Can.

6. Apply anti-crack mortar to the thermal insulation mortar with a thickness of 2MM.

7. Hang alkali-resistant mesh cloth on the surface of the anti-crack mortar.

8. Finally, apply 2-3MM thickness of anti-crack mortar on the alkali-resistant mesh cloth again.

9. After the construction of the protective layer is completed, the subsequent surface layer construction can be carried out after curing for 2-3 days (depending on the temperature). </p
