A kind of automatization vacuum chemistry coating apparatus as above, is characterized in that described electric heating tube is coil pipe.
The invention has the beneficial effects as follows:
1. the present invention utilizes vacuum generator or vacuum pump to vacuumize tank interior, negative pressure makes plating solution boiling point lowering produce a large amount of bubble fully to stir plating solution, avoid traditional employing pressurized air and carry out the drawback that stirring can introduce impurity, prepared plating solution layer porosity significantly reduces.
2. the present invention makes the reduction of boiling point effectively control the temperature of plating solution, extend the work-ing life of plating solution, originally about the plating solution in 2-3 cycle can only being used can to use now 5 cycles, add and can supplement plating solution, more easily realize the thick liquid layer of plating.
3. tank body of the present invention have employed stainless material and makes, and not only intensity is high to be provided with at inwall the structure adding polytetrafluoroethylene floor, and does not easy to usely need Passivation Treatment, solves the difficult problem that traditional tank body uses loaded down with trivial details easy pollution plating solution.
4. the intellectuality of height, can automatically detect liquid level and supplement, be easy to accomplish scale production.
