1, the pressure must be enough. The current buildings are generally more than 50 meters, without enough pressure, the efficiency will be low;
2. The spraying effect must be smooth. At present, the economic environment is sluggish, and any waste should not be made. The smooth spraying surface is generally about 5 mm, which saves a lot of raw materials for subsequent smoothness;
3. Polyurethane foam is easy to block the gun head, and the high-pressure spray gun with self-cleaning function can survive in today's competitive environment of pursuing high efficiency;
It is recommended that Jinan Chida polyurethane foaming machine equipment is quite good. You can go and have a look.
