When pasting, according to the characteristics of the foam glass insulation system material, it is advisable to use a toothed trowel to apply the disposed foam glass bonding mortar to the base wall and the foam glass, and then firmly adhere the foam glass to the base wall. On the surface, at the anchor reinforcement position, the docking is performed with foam glass. When using anti-cracking mortar leveling construction, the flatness deviation should not exceed ±4mm, it should not be too thick, mainly for leveling, the thickness of plaster should be slightly higher than the thickness of the standard rib, and then scraped with a ruler. The trowel is partially repaired and flattened; after the surface layer is found to be wiped for 30 minutes, the wall surface is smeared with a trowel, and the construction of the crack-resistant layer and the facing layer can be carried out after the acceptance of the line ruler reaches the acceptance standard. Foam glass should also be attached to the door and window openings to block the heat bridge and improve the insulation effect of the building.
For the building with the facing layer as the tile, the foam glass system technology emphasizes the use of nails or anchor bolts to connect with the base layer, and the four-angle steel wire mesh is bundled with the tail wire anchored wire. When the four-angle wire mesh bundle is uneven, it must be pressed with steel nails. Thin iron sheet, the steel mesh is fixed on the foam glass to ensure the smooth construction of the subsequent process of the wire mesh bundling. Through the reinforcement measures such as nailing, expansion bolts, galvanized steel wire and four-corner mesh, the effect of the brick load on the surface layer can be transmitted to the stable base wall, which acts as an isolation protection for the insulation layer and also enhances the protection. The insulation layer and the cement cracking mortar have good gripping force, and the tensile layer is subjected to the tensile force from the horizontal direction and the vertical direction, thereby greatly improving the strength of the surface layer of the tile, and further ensuring the earthquake resistance and wind resistance of the heat preservation system. Pressure capacity.
Foam glass exterior insulation technology has been well applied in many major projects in Beijing and Tianjin, and has accumulated rich experience. Make full use of its own technical advantages and application experience to guide the design and construction of such current technical systems in China. Insulated foam glass for installation is suitable for thermal equipment, pipes, containers and refrigerators. The products are made into plates, blocks, slabs or arches.
This material can be used in the temperature range of -260~+500 °C. The use of foam glass for thermal insulation varies in different temperature ranges.
(1)The construction method when the temperature is higher than 100 °C is generally fixed by wire or metal strip, or fixed by bolts or angle irons, or bonded with high temperature adhesive. If a paste such as water glass is used, it is necessary to perform point bonding, and the joint may be made of tar epoxy filler or clay mud.
When used as an external material, foam glass products with good airtightness and flame retardancy and climate adaptability should be selected. The construction methods are as follows.：
① Wrapped in oil felt or glass cloth, covered with iron；
② Coated with mastic, wrapped in glass cloth, and then coated with mastic；
③ Applying concrete；
④ Covered with asbestos；
(2) When the temperature is lower than -30 °C, the construction method is between -30 °C and -70 °C. In addition to the dense assembly with the foam sealing material, a metal strip must be tied every 230 mm to fix it; At 70 ° C, generally no binder is used, but a multi-layer assembly of layers or more is used, and from the second layer, the filler is filled with a filler. Then tie the band and apply the exposed layer to the low temperature mastic。
