Problems solved by technology

That is to say, these experimental devices that are temporarily used together (or the way they are temporarily used together) not only pose a safety hazard, but also often cause the experiment to fail to proceed smoothly due to a small error

Abstract

The invention discloses a device for an electroplating experiment. The device comprises a beaker for containing electroplating liquid, an electric heating panel for heating and preserving heat for the beaker, electrode plates inserted in the electroplating liquid, and a DC voltage stabilized and current stabilized power source connected with the electrode plates through a guide line, wherein the electric heating panel is covered with a convex shield; the inner sides of the shoulder parts of the shield are placed on four edges of the electric heating panel; two to four beaker holes are formed in the top surface of the shield; the beaker penetrates through the beaker holes to be placed on the electric heating panel; four or eight hollow columns are symmetrically arranged on the outer side faces of the shoulder parts of the shield; the upper end of each hollow column is plugged with a heat insulating plug; four heat insulating plugs form a support group to fixedly support a pair of mesh enclosures; the guide line for connecting the electrode plates and the DC voltage stabilized and current stabilized power source is a grid mesh penetrating through the mesh enclosures. The device can ensure that the electroplating experiment is carried out in a safe and smooth manner, prolongs the service life of the electric heating panel, and increases the recycling times of the beaker.

Description

technical field [0001] The invention relates to a device used in electroplating experiments in school laboratories. Background technique [0002] Electroplating is an important process to protect and beautify the surface of metal products. Therefore, not only corresponding theoretical courses are set up in chemistry teaching, but also one of the important contents of experimental courses. The electroplating experiment is divided into four steps. The first step is alkali cleaning—use 50-60°C alkali washing solution to pre-treat the surface of the iron product to be electroplated for rust removal and impurity removal; then clean it with water, and polish its surface to a bright finish. The second step is alkali immersion - put the iron products that have been polished and cleaned again with water into the alkali washing solution at 20-40°C for 5-10 minutes (while stirring continuously). The third step is acid leaching—the iron products that have been cleaned with clean water...
