7. the automatic mixing system of two component paint, it is characterized in that adopting fluid non-return valve, first material and the second thing had installed the first material check valve and the second material check valve before entering blender, prevent material adverse current, cause the first material to enter wrong phenomenon that the second material-transporting system or the second material enter the first material-transporting system.
8. an automatic mixing system for two component paint, is characterized in that adopting explosion-proof solenoid valve island, and electromagnetism valve island is used for controlling the pneumatic control fluid switching valve used that native system uses, and explosion-proof solenoid valve island meets and uses in inflammable and explosive environment.
