What are the advantages of polyurethane foaming machine? Feedback from customers we understand，BLingxinPolyurethane foaming machineFoaming has the following characteristics:

1. Simple and fast construction. Each day can spray more than 200 square meters, conducive to the schedule.

2. Good bonding performance. Can and wood, metal, brick, glass and other materials bond very strong, not afraid of the wind.

3 for new roof or old roof maintenance is very suitable especially old roof repair, do not have to eradicate the original waterproof layer and insulation layer, just clear the surface of ash, sand, can be sprayed.

4. Good insulation performance. Thermal conductivity of about 0. 025, better than polystyrene board, is a good building insulation material.

5. It is waterproof. Foam hole is closed, closed rate of 95%, rain will not penetrate through the hole.

6. As a result of field spraying, the whole waterproof layer is formed, and there is no seam, which is inferior to any polymer coil, reducing the maintenance workload.

7. Simple structure of closing head. Spray foaming polyurethane, no special treatment, greatly simplified. If the use of coil, parapet in the place, need to leave a groove, the head in the groove; If you can not leave a groove, with flat iron seal nail head, but also apply caulking paste.

8. Good aging resistance. According to abroad already with project summary and research test know, be able to bear ageing fixed number of year can amount to 30 years long.

9. Good economic benefits. If the insulation layer and waterproof layer separated, not only high cost, but also a long time, and the foam polyurethane survive.
