During the construction of EPS molded polystyrene insulation board, in order to ensure the construction quality and safety, the following key points need to be noted:
1. Preparation before construction
Material preparation: Select EPS molded polystyrene insulation board with a certificate of conformity, and check whether its appearance quality and size meet the requirements. At the same time, prepare an appropriate amount of special adhesives, anchors, fiberglass mesh and other auxiliary materials to ensure that the material quality is qualified and meets the design requirements.
Base treatment: Thoroughly remove the floating dust, oil stains, release agents and other materials that affect the bonding strength on the surface of the base wall, and ensure that the base is flat, dry, and free of impurities such as oil stains. For the insulation renovation project of old houses, the original exterior finishing layer should be removed and the base wall should be repaired and leveled. Base treatment is the basis for the construction of EPS molded polystyrene insulation board, and has a direct impact on the subsequent construction quality.
2. Construction operation
Apply adhesive: Let the prepared bonding mortar stand for 5 minutes and stir evenly, then use a scraper to evenly apply high-quality adhesive on the base. Pay attention to controlling the amount of adhesive to ensure that it is evenly applied without omission.
Pasting EPS molded polystyrene insulation board: Place the pre-cut EPS molded polystyrene insulation board in the predetermined position, keep it horizontal, and tap it with a mallet to make it fully contact with the adhesive. During the pasting process, pay attention to the degree of tightness between the boards to ensure that there are no gaps. At the same time, when using the point bonding method or the full bonding method, ensure that the area of bonding mortar is not less than 40% of the area of the insulation board to ensure a firm bond.
Install anchors: The anchors are installed 8 hours after the insulation board is pasted, and it is advisable to complete it within the next 24 hours. Use an impact drill to drill holes at the position required by the design. The hole diameter is generally 10mm, the depth of drilling into the base wall is about 60mm, and the depth of drilling into the base wall of the anchor is about 50mm. When installing anchors, ensure that they are firm and reliable to improve the stability of the insulation board.
Dealing with gaps: A certain gap should be maintained between the insulation boards to eliminate slurry bubbles and improve the insulation effect. For the gaps formed, they should be filled with insulation strips and smoothed in time to ensure that the board surface is flat.
3. Construction safety and environmental protection
Fire prevention measures: EPS molded polystyrene insulation board is a flammable material. Fire extinguishing equipment should be set up at the construction site and fire prevention regulations should be strictly observed. At the same time, EPS molded polystyrene insulation board should be kept away from fire sources and avoid direct sunlight during storage.
Waterproof measures: Although EPS molded polystyrene insulation board has certain waterproof properties, waterproof measures should still be taken during construction. Before pasting EPS molded polystyrene insulation board, the wall should be waterproofed to prevent moisture penetration from affecting the performance of EPS molded polystyrene insulation board.
Environmental protection: During the construction process, the emission of pollutants such as noise and dust should be minimized, and products with good environmental performance should be given priority. At the same time, the garbage on site should be cleaned up in time after construction to keep the environment clean.
In summary, during the construction of EPS molded polystyrene insulation board, attention should be paid to aspects such as material preparation, base treatment, construction operation, construction safety and environmental protection. By strictly abiding by the construction specifications and precautions, the construction quality and use effect of EPS molded polystyrene insulation board can be ensured.
