Cold storage spraying is to make the cold storage more and more thermal insulation, to achieve thermal insulation effect, is also a spraying technology. Today, I will mainly explain the detailed operation method of polyurethane spraying in cold storage spraying.
1. The base wall must be liquidated and clean, and the wall surface should be free of oil, dust, dirt, paint, soil and other pollutants or other materials that hinder spraying. Remove the protrusions on the wall to make it clean and flat.
2. Spray moisture-proof primer on the exterior surface of the wall. The primer should be applied evenly and thickly when spraying. There must be no omissions on the exterior of the wall. The primer should be used within 2 hours when using the primer. The remaining primer cannot be used again.
3. Spray coating along the top corner of the wall to achieve better insulation effect in the cold storage. At the same time, the strength of the polyurethane foam will be higher without cracking or falling.
4. Foam molding is directly radiated to the surface of the object, the material is abundant on average, and the pollution is small.
The above is the construction process of polyurethane spraying in cold storage spraying. For more exciting content, please pay attention to us.
