Which step is necessary before polyurethane spraying construction? It is undoubtedly the debugging process, which is the preparation that users must do before construction. Let's take a look together below!
The debugging process is indispensable before polyurethane spray construction. The user adjusts the equipment to the temperature and pressure parameters required by various materials for preheating. First, pay attention to mixing material B before spraying. It is strictly forbidden to add any substance to material A and material B on site, and it is strictly forbidden to mix up the feeding system of material A and material B. Second, please note that before the formal spraying operation on each working day, a sample block of 150mmx300mm and different thickness should be sprayed on the construction site first, and the construction technical supervisor will evaluate the appearance quality and keep the sample for future reference. When the appearance quality of the coating meets the requirements, the process parameters can be determined and the spraying operation can be started.
The above briefly describes an indispensable preparatory work before applying polyurethane spraying. For more information on polyurethane, please continue to pay attention to Hightop Machinery.
