Problems solved by technology

[0003] At present, most of the polishing fluids of grinding machines are mixed with brighteners, brighteners and water. After polishing, polishing dead angles are prone to appear, and the grinding is not thorough. Some products are easy to adhere to dirt in the corners, and it is difficult to clean, even with the help of a washing machine. , which brings inconvenience to the production, which puts forward requirements on the polishing effect of the polishing liquid

Abstract

The invention provides an environment-friendly grinding and polishing solution. The polishing solution comprises the following components including, in percentage by weight, 2%-20% of organic acid, 0.5%-10% of a corrosion inhibitor, 0.5%-12% of a surfactant, 0.1%-15% of a brightening agent and the balance water. The polishing solution has no toxic influence of traditional nitric acid and has no environmental pollution caused by a phosphoric acid system. The adopted polishing solution is an organic acid environment-friendly system, is harmless to human bodies and the environment, can overcome polishing dead angles, and has the effects of a cleaning agent and a polishing agent, so that a polished product is clean and free of oil stains, and the surface has a mirror bright effect.

Description

technical field [0001] The invention relates to the field of metal polishing liquid, in particular to an environment-friendly grinding and polishing liquid. Background technique [0002] Alloys, such as zinc alloys, magnesium alloys, aluminum alloys, copper alloys, and stainless steels, are widely used in precision machinery manufacturing, such as electronics, automobiles, chemicals, and medical equipment. Moreover, the requirements for these precision parts and components are getting higher and higher, not only must they be durable, but also have a clean, mirror-like, and bright appearance. [0003] At present, most of the grinding machine polishing fluids are mixed with brighteners, brighteners and water. After polishing, polishing dead angles are prone to appear, and the grinding is not thorough. Some products are easy to adhere to dirt in the corners, and it is difficult to clean, even with the help of a washing machine. , which brings inconvenience to production, which...
