Problems solved by technology

[0004] The existing chemical polishing methods mainly use acidic chemical polishing liquid (containing phosphoric acid, sulfuric acid and nitric acid, commonly known as three-acid polishing liquid). The advantages of acidic chemical polishing liquid are: better polishing effect, bright and smooth surface of polished parts The disadvantage is: a large amount of NOx gas will be produced during the polishing process, which will seriously pollute the environment

Abstract

The invention discloses a pedal bicycle frame surface polishing treatment technology, and relates to the technical field of bicycle manufacturing. The pedal bicycle frame surface polishing treatment technology comprises the following steps including the first step of ethanol solution ultrasonic auxiliary dipping treatment, the second step of pretreatment liquid preparing, the third step of pretreatment liquid treatment, the fourth step of polishing liquid preparing and the fifth step of polishing treatment. The pedal bicycle frame surface polishing treatment technology is provided. Through preparing of pretreatment liquid, surface treatment is conducted on a pedal bicycle frame, the polishing efficiency of the pedal bicycle frame in polishing liquid can be effectively improved, the polishing effect is further improved to a certain degree, and surface brightness is enhanced.

Description

technical field [0001] The invention belongs to the technical field of bicycle manufacturing, in particular to a process for polishing the surface of a pedal bicycle frame. Background technique [0002] A bicycle, also known as a bicycle or bicycle, is usually a small land vehicle with two wheels. After a person rides on the car, it is powered by pedals, which is a green and environmentally friendly means of transportation. English bicycle. Among them, bi means two, and cycle means wheel, that is, a two-wheeled vehicle. There are many types of bicycles, including single bicycles, tandem bicycles and multi-person bicycles. [0003] Bicycle frame materials are mostly made of aluminum alloy materials, and the methods for polishing the aluminum alloy surface mainly include mechanical methods, electrochemical methods, and chemical methods. Mechanical polishing and electrochemical polishing have certain requirements on the shape and size of parts, so their use is limited. How...
