Problems solved by technology

If the preparation method of the lead alloy mounting sample is directly applied to the preparation of the plate corrosion layer mounting sample composed of lead alloy and active material, since the plate is soft, direct wire cutting sampling of the plate will easily cause the active material to fall off And the structural damage of the corrosion layer of the plate, and even cause the harm of lead to personnel and the environment

Abstract

The invention discloses a sample mounting method for a lead-acid battery pole plate corrosion layer, belonging to the technical field of metallographic sample preparation. It is characterized in that: the preparation of polar plates, the preparation of sample mounting molds, the preparation of epoxy resin mounting materials, the first sample mounting, wire cutting sampling, and the second sample mounting. The invention fills up the gap in the production method of the corrosion layer of the lead-acid storage battery, and is simple to operate, does not destroy the tissue structure of the corrosion layer of the pole plate, is safe and reliable, and is especially suitable for positive and negative raw plates of the lead-acid storage battery. Metallographic mounting of the corrosion layer of the negative plate.

Description

technical field [0001] The invention relates to the technical field of metallographic sample preparation, in particular to a sample mounting method for a lead-acid storage battery electrode plate corrosion layer. Background technique [0002] The corrosion layer structure of the lead-acid battery plate is related to the performance of the battery, especially the PCL-1 (early capacity loss) failure phenomenon of the lead-acid battery. It is of practical significance to observe the structure of the corrosion layer of the plate under microscopic observation, and to study the influence of its structure change on the performance of the battery. Since the pole plate is a two-phase material composed of lead alloy and active material, its texture is quite soft, and it will deform under low pressure, and even the active material will be peeled off from the grid. At the same time, lead is toxic. In the process of preparing samples, the pollution of lead to personnel and the environme...
