Brass sheet polishing refers to the selection of a reflection of the effect, so that the surface of brass sheet is not smooth level shrink, make it more and more bright, leveling the surface of the solution.
The key to polishing brass is to adopt two methods: mechanical chemical method and physical method. Chemical changes take sanding and polishing: is an energy saving solution made on brass surfaces. Generally, acid is used to polish and polish, and the brightness level is adjusted according to the provisions.
The solution process of brass chemical polishing:(1) polishing production and processing can not be carried out in the wet, which will be more serious harm to the quality of polishing. Please use stock polish solution and ensure that the operation is performed at room temperature and under natural ventilation.
(2) Put the brass sheet into the polishing and throwing light source liquid, take it down after about 3 minutes, and put it into the water to clean up, and remove the liquid medicine on the surface of the copper material.
(3) the brass sheet is polished and cleaned clean before moving on to the next processing technology, painting and passivation treatment, in order to ensure that it is not easy to fade again, the brass sheet should be blown dry and passivation treatment in the outdoors.
(4) In the polishing production and processing of brass sheet, when it is found that the smoothness of brass sheet is not significantly insufficient, some efficient preservatives should be added to the polishing light source liquid. The added liquid volume is about 1.5% of the polishing fluid. If the color of the polishing liquid is dark green, and the experimental reagent liquid is still not up to the specified requirements, we should replace the center of gravity of the polishing liquid to take polishing process.
Physical reactions take the form of grinding and polishing: continuous friction according to mechanical equipment.
