Problems solved by technology

In the middle of the two-step cleaning method, in order to prevent the first process from polluting the chemical reagents in the second process, processes such as alcohol washing, water washing or drying are added, so there are disadvantages such as complicated processes, large floor space, and high processing costs.
[0006] At present, the oxide layer cleaning process of mixing three acids of hydrochloric acid, nitric acid and sulfuric acid is often used. The combined action of the three strong acids makes the alloy foil corrode faster. Because of the thinner foil and the different corrosion rates of different metal elements, it is easy to Erosion occurs in some areas of the foil, and the strong acid solution is volatile, and the acid mist will easily cause corrosive damage to workers and production equipment. Therefore, there are obvious environmental protection and safety hazards in the direct use of strong acid treatment.

Abstract

The invention discloses a cleaning agent for cleaning the surface of a foil, comprising: hydrochloric acid, a surfactant, ethanol and water; its components are configured according to the following parts, wherein the hydrochloric acid is: 120ml-20ml; the surfactant For: 50g‑150g; for ferric chloride: 20g‑25g; for ethanol: 150ml‑250ml; for water: 400ml‑500ml. The invention also discloses a preparation method and a cleaning method of a cleaning agent for cleaning the foil surface. Through the above embodiments, the oxide layer on the surface of the foil can be corroded and cleaned in a directional manner, the oil on the surface of the foil can be quickly removed, and an organic active area can be formed at a specific position on the surface of the foil, which can improve the bonding between the foil and the organic base adhesive Effect.

Description

technical field [0001] The invention relates to a cleaning agent for cleaning the surface of a foil material, a preparation method and a cleaning method thereof. Background technique [0002] Weighing strain gauge is a device that can measure the force of elastic body by measuring tiny resistance changes. Its production and processing mainly include important processes such as foil surface treatment, foil lamination, etching circuit, welding electrode and organic packaging. [0003] Foil surface treatment, as the first important process in the production of strain gauges, is a key process that affects the final performance of strain gauges. [0004] Foil materials are generally alloys such as nickel-chromium-copper. During heat treatment and rolling forming, the surface is easily oxidized and rolling oil remains, and the surface layer is dense, and the oxide layer is difficult to remove. These residual pollutants will not only affect the strain gauge Sensitivity coefficient...
