In use, first wiping suction piece platform with wet cloth, aluminium foil pole piece is attached on suction piece platform by label, scrapes aluminium foil with spatula
Moisture under piece simultaneously strikes off aluminium foil, forms moisture film around aluminium foil under the tension of water, and aluminium foil bottom is vacuum state, therefore aluminium foil
Suction piece platform finally can be put into chassis along lower layer's sliding slot, the card on turn chassis is fixed with strong adsorption on suction piece platform by piece
Suction piece platform.
Patch slot by the film patch for meeting requirement of experiment thickness, width along scraper ontology is pasted on scraper, will be scraped
Knife is placed on aluminium foil pole piece and is close to fixed cross beam.The bolt on fixed cross beam is adjusted, centrum is pressed into the cone on scraper ontology
Shape card slot, fixed doctor.Coat on aluminium foil pole piece, gently pushes fixed cross beam that coating can be completed.
The invention has the following advantages over the prior art:
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.
