1, aluminium foil surface is smooth, is conducive to coating, is not in the case where coating scatters；
2, tempered glass is quick detachable, suction piece platform easy cleaning；
3, scraper uses change paster mode, and common four kinds of specifications are tested in thickness setting, and width can be according to requirement of experiment
It voluntarily cuts, cost substantially reduces；
4, the coating surface applied out is standard rectangle, guarantees that the quality of each pole coating, density are identical, controls coating
Quality, density parameter are unified；
5, the coating both sides of the edge applied out are taken without coating convenient for experimenter, will not be due to artificially touching edge coating
Cause coating quality error；
6, guarantee that coating locus is identical, improve the repeatability of coating.
7, single unit system structure is simple, figure small volume and less weight, low in cost, is suitable for laboratory batch and uses.
