Improved fresh keeping method during Mongolian oak leaf processing course

During the pickling and desalting course of Mongolian oak leaf, certain amount of improver comprising sodium hydrogen hyposulfite and tripolyformaldehyde is added and acid condition is maintains, that is, acidifying agent citric acid with or without sodium hexametaphosphate is added to control the pH value of pickling solution to 3.5-4.0, that of desalting water to 3.5-4.5 and that of soaking liquid to 2.0-3.0. After desalting, green returning agent copper salt is added to restore green.

Spray cup for electrode plating of silicon solar cell

The invention discloses a spray cup for electrode plating of a silicon solar cell, which solves the problem of the low ratio of the area occupied by polysilicon of a single solar cell and the area occupied by a printed wire in the prior art.
