Treating agent for aluminum case of controller of electric bicycle and preparation method of treating agent

Abstract

The invention discloses a treating agent for an aluminum case of a controller of an electric bicycle and a preparation method of the treating agent, and belongs to the technical field of chemical descaling. The treating agent consists of citric acid, tartaric acid, octanol polyoxyethylene ether, coconut oil diethanoamine, sodium sulfate fatty alcohol-polyoxyethylene ether, lauryl sodium sulfate, lauryl sodium sulfate, triethanolamine, hydrochloric acid, hydrofluoric acid and deionized water. The components are mixed and uniformly stirred to obtain the treating agent. The treating agent is a cleaning agent which is good in descaling effect, strong in cleaning force, convenient to use, environment-friendly, high in biodegradation rate and green and environment-friendly. In addition, the treating agent is extremely low in corrosion rate to equipment.

Description

technical field [0001] The invention relates to the technical field of chemical descaling, in particular to an aluminum case treatment agent suitable for electric bicycle controllers and a preparation method thereof. Background technique [0002] The electric bicycle controller (hereinafter referred to as the controller) is composed of internal electronic components, circuits and shells, with undervoltage, current limiting or overcurrent protection functions, and is used to control the start, operation, speed, stop and Other electronic devices are the key components of electric bicycle motor speed control. The shell of the controller has two functions, one is to dissipate heat from the internal power tube and other electronic components and circuits, and the other is to avoid or alleviate the touch of the controller during riding. At this stage, the controller shell generally uses 6063 aluminum alloy as the main raw material (a low-alloyed AL-Mg-Si series high-plasticity al...

Problems solved by technology

[0004] At this stage, the controller manufacturers mostly treat the recycled old controller casings as waste products and treat them as recycled materials, and the residual value is less than 10% of the original value. In this way, the production cost of the enterprise increases, and it also causes a huge waste of aluminum metal resources; recently, there are A small number of controller manufacturers have tried to use industrial strong acid to treat the recycled controller casing, and have achieved some results. However, there are many disadvantages in the treatment of industrial strong acid. First, for the aluminum controller casing, improper treatment will easily cause the controller casing to corrode. Reduce the heat dissipation efficiency of the controller shell; second, it is easy to significantly change the inner cavity size of the controller shell, increasing the difficulty of assembly operations; third, the working environment is harsh, and a large amount of acid mist formed by strong acid during processing is strongly irritating to the body of the operator , is not conducive to the physical and mental health of personnel, and is easy to cause personal injury accidents; Fourth, pickling waste is a hazardous chemical waste, and improper discharge will have adverse effects on the environment, which does not conform to the development trend of environmental protection and clean production in today's society
