Application Of Polyurethane Spraying Machine In Roof Insulation Project

The roof is one of the important components of the building. In addition to the structure, the important function is waterproof and heat preservation. Traditional roof waterproofing has morbid conditions, such as water leakage, cold, mildew, etc. The roof structure is easily damaged and leaks, causing water leakage, and it is difficult to find leaks, and maintenance is difficult and expensive.

1. Reasons for using polyurethane spraying machine for roof insulation

1. The panels used for traditional roof insulation will damage the panels and fall off the corners during transportation and handling. Insulating plates must be assembled to create gaps and easily generate hot and cold bridges. After use, it will shrink and deform, make the gap between the plates larger and form a hot and cold bridge, and common problems will occur, such as local leakage, slow frost, hair growth and mold.

2. Traditional roof insulation and waterproof multi-layer structure, the structure is self-weight, the process interval is long, and the entire roof takes too long. The traditional roof is insulated and waterproof, with single function, complicated process, waterproof but not heat insulation, and heat insulation and not waterproof.

2. Equipment comparison of polyurethane spraying machine

Different from polystyrene board and extruded board, polyurethane spray is a kind of thermosetting material with both waterproof and heat insulation functions. It is sprayed on site, continuously formed, and has no rigid foam joints. It also has the functions of fire prevention, heat preservation and waterproofing. In the past, ordinary materials used the traditional model of "insulation is not waterproof, and waterproof is not insulated". The roof is insulated and waterproof, and the house is covered by a cotton jacket and raincoat. This can prevent common insulation materials and panel joints from playing a single role, otherwise it will cause local water seepage, frost and mildew on the roof and external walls.

Third, the advantages of polyurethane spraying machine construction

1. Insulation and waterproof are integrated, the insulating layer is not waterproof, and the waterproof layer is not insulating. Once the waterproof layer penetrates, the insulating layer will disappear.

2. Construction directly on the floor can lock the source of water leakage, completely solve the long-standing water leakage and multi-seepage phenomenon of the roof, and is convenient for maintenance.

3. The construction of the polyurethane spraying machine is simple and quick, and the multi-layer integration reduces the construction period.

4. The complex and special-shaped sloped roof is easy to construct, and the waterproof and heat preservation mechanized construction is sprayed with water and seamlessly bonded to gradually form a heat preservation and waterproof layer.
