Pre-construction preparations required for the base material to be constructed :
1. Before spraying, fully cover the areas that do not need to be sprayed.
2. Generally, doors and windows are covered with plastic colored strips of cloth cut into pieces equal to the area of the door and window. For irregular parts that need protection such as shelves, , iron art, etc., polyethylene cling film should be used for wrapping and protection.
3. The area around the spraying operation should be enclosed and shielded to avoid polluting the environment.
4. Polyurethane particles will blow away in the wind and pollute the environment. It is strictly forbidden to operate with open flames such as electric welding. Sufficient fire extinguishers must be prepared during construction to prevent on-site fires.
5. Before construction, the walls and roofs should be inspected, and the floating dust on the surface should be cleaned. If there is any oil stain, clean it with an organic solvent, and then wipe it with a clean rag. Debris and other debris can be shoveled away with shovel and , and then blown clean with compressed air. The cleaned roof should be clean, free of debris, foreign matter, and oil stains.
Polyurethane spray foaming construction site
Preparation of construction workers before construction : ( polyurethane foam splash is easy to occur during spraying, construction workers must take labor protection.)
1. Construction workers strictly follow the safety regulations for high-altitude operations and must wear Safety helmets, safety belts, especially effective protective measures must be taken during hanging basket construction to prevent the hanging basket from falling.
2. New workers must receive strict technical training and safety education before taking up the job.
3. The installation operators of spraying electrical equipment must be certified to work, and the use of electricity must be strictly in accordance with the construction site management regulations.
