Problems solved by technology

[0003] However, there are still deficiencies in the above-mentioned technology. Before using the aluminum foil to do the electrolysis experiment, the lead content in the aluminum foil is not detected first. Whether the direct contact of the staff will cause harm to the human body, while the traditional detection of lead in the aluminum foil Whether the content of lead exceeds the standard is usually put the aluminum foil paper on the alcohol lamp to imitate the roasting process, then soak the burned aluminum foil paper in distilled water, and then drop in the reagent. If the liquid turns red, it means that the lead exceeds the standard; if it turns blue , it means that the lead does not exceed the standard. During the detection process, the hand-held alcohol lamp is prone to shaking up and down and left and right, which may lead to inaccurate detection

Abstract

The invention provides a trapezoidal shielding device produced by corrosion foil for lead-free electrolytic capacitors. The trapezoidal shielding device produced by the corrosion foil of the lead-free electrolytic capacitor comprises: a trapezoidal shielding device body; two L-shaped round rods, and the two L-shaped round rods are fixedly installed on the trapezoidal shielding device body; a horizontal plate , the horizontal plate is arranged below the two L-shaped round bars; two first grooves, the two first grooves are set on the top of the horizontal plate; two first horizontal bars, The two first crossbars are respectively rotatably installed in the two first grooves, and one end of the first crossbar extends out of the corresponding first grooves. The trapezoidal shielding device produced by the corroded foil for lead-free electrolytic capacitors provided by the invention has the advantages of being easy to use, capable of uniformly detecting whether the lead content in the aluminum foil exceeds the standard, avoiding injury to workers, and simple and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of electrolysis, in particular to a trapezoidal shielding device produced by corrosion foil for lead-free electrolytic capacitors. Background technique [0002] Lead is a soft and malleable weak metal, poisonous, and heavy metal. The original color of lead is blue-white, and the surface of lead is quickly covered by a layer of dark gray oxide in the air. It can be used in construction, lead-acid batteries, warheads, Cannonballs, welding materials, fishing gear, fishing gear, anti-radiation materials, trophies, and some alloys, such as lead-tin alloys for electronic soldering, the so-called "lead-free" does not mean that the existence of lead is absolutely prohibited, but requires Lead content must be reduced to less than 1000ppm, which means that electronic manufacturing must meet the requirements of lead-free assembly process. "Lead-free electronics" is also commonly used to refer to the content of six toxi...
