In the process of car paint spraying, the paint spray hose is an important transmission channel in the spraying system. It is responsible for transporting paint from the storage tank or color mixer to the spray gun. At the same time, it also needs to transport gas, such as compressed air, to drive the spray gun. In car paint spraying, it is very important to choose the right hose material. Because this directly affects the quality and effect of spraying. Now, let me introduce you three common paint spray hose.
PU air hose
This hose is made of high resilience polyurethane raw material and has excellent softness. It is usually used as an air hose, especially in the application of manual and automatic spray gun air intake pipes.
PE oil hose
PE oil hose has corrosion resistance. Compared with PU hose, it may be slightly harder. In car paint spraying, PE oil hose is often selected for the oil intake pipe of the spray gun, especially in pressure-feeding and automatic spray guns.
Thermoplastic hose
This hose is generally made of outer PU and inner Teflon, which combines the advantages of PU air hose and PE oil hose. It has both the softness of the pipe body and the corrosion resistance. Therefore, it may be used in some spraying occasions with special requirements.
