The best concentration of the bath is formulated. In general, it is formulated according to the following methods.
Tank liquid preparation: 2/3 volume of water in the tank, add the amount of YH30zv^ grease agent, dissolve the circulation pump, and then add water to the specified volume, test and adjust the parameters to the process range, can be put into use. In the process of treatment, the free alkalinity is reduced and the degreasing ability is reduced. At this time, some degreasing agents must be supplemented to the range of free alkalinity, and the bath liquid can be used for a long time.
