In the shape of a spiral or coating sagging.
Rotating speed n is typically calculated as follows with spray gun speed of travel V：N=120*V/L, wherein L are spraying swath, value model
Enclose for 180mm~220mm, typically take intermediate value.And rotating speed n with spraying linear velocity T-phase close, linear velocity T typically 300mm/s~
Between 400mm/s.T=n* π D/60, wherein D are diameter of work.It can be calculated according to above-mentioned formula：Workpiece rotational frequency n=6.25r/
Min, spray gun speed of travel V=5mm/s.
4th, spraying compressed air pressure is an important factor for influenceing film thickness.When air pressure reaches the critical shape of sagging
During state, the surface effect of coating is optimal.Therefore, compressed air pressure can be controlled according to practical condition, makes the coating of ejection
It is always ensured that the optimum efficiency general control for reaching spraying is preferable in 0.3MPa~0.4MPa like the state for flowing non-streaming.
