Application method of aluminum silicate equipment thermal insulation coating

A, aluminum silicate insulation coating using the method:

1. According to the thermal insulation mortar: water = 1:0.8-1.2 weight ratio ingredients.

2. Pour the clear water into the bucket first, then add the thermal insulation mortar, stir it into a uniform paste with a power agitator, let stand for 3-5 minutes, then stir it slightly and use it.

3. Apply evenly on the work surface with a scraper or spatula.

4, after 3-7 days of maintenance can proceed to the next process.

5. Reference dosage: When the base surface is flat and the thickness of the insulation layer is 15 mm, the dosage is about 4.5-6.0 kg/m2.

Second, the construction process:

Interfacial treatment of the base layer: the base layer should be a mortar base layer that has been brushed with cement mortar, which is smooth, firm, free of empty drums, cracking and the like. The flatness of the wall should reach intermediate plastering ≤ 4mm.

Third, the acceptance criteria:

1. Batch scraping 10-30mm thick composite aluminum silicate thermal insulation mortar. After the construction of the thermal insulation layer is completed for 2-3 days, all the insulation layers are dry before scraping the polymer waterproof anti-cracking plaster.

2, facing tiles: the surface of the composite insulating layer silicate insulation mortar waterproof polymer layer Scraping cracking surface mortar, then plated zinc plated steel mesh, with nine per square studs fixed, then the batch Scrape the polymer waterproof and anti-cracking mortar, and finally use the strong tile stone binder and the color waterproof and mildew-proof grout to complete the paving and caulking work of the facing brick.

3. Coating finish: scrape a layer of polymer waterproof anti-cracking plaster on the surface of composite aluminum silicate thermal insulation layer, then flatten the alkali-resistant glass fiber mesh, and then apply a layer of polymer waterproof Cracked mortar, corners and door and window openings for reinforcement. The polymer waterproof anti-cracking mortar and the alkali-resistant glass fiber mesh fabric together form a protective layer of the heat preservation system, and then the flexible special putty is scraped, and finally the finish paint is applied.
